    Hybrid Solar Panels – Solar Energy for beginners

    Today we come back with a new entry of “Solar Energy for Beginners” where we will talk about hybrid solar panels for some, and mixed panels for others. If this is your first time hearing any of these terms, don’t worry; there are still people who have been in the solar energy sector and within the renewable energy sector for a long time and who, till this day, do not know it.

    Do you want to know more about the innovative hybrid solar panels? Do not miss then everything we have to tell you below.

    What is a Hybrid Solar Panel?

    A hybrid solar panel is the combination of thermal and photovoltaic technologies in a single module; In front of the photovoltaic and thermal panels that, conventionally, are installed separately, emerges the hybrid solar panel, capable of simultaneously generating electricity and heat. This is due to the ability of the hybrid solar panel to be able to take advantage of the entire spectrum of existing light, unlike photovoltaic and thermal panels, which capture ultraviolet and infrared light respectively. Photovoltaic solar energy and thermal solar energy are used at the same time.

    Although it is an existing product since the 70s, it has not been until now when this technology has begun to be installed in more and more places. Its versatility, its high degree of innovation and the multiple advantages that hybrid solar panels have compared to conventional technology have made this type of solar panels increasingly in demand in all types of sectors and for all kinds of locations.

    Electricity, sanitary hot water and even heating if the system allows it (ideally underfloor heating and low-temperature emitters) in a single panel. Sounds interesting, don’t you think?

    What types of hybrid solar panels are there?

    Throughout these years, the market for hybrid solar panels has been evolving and bringing new models available depending on the technology they have been incorporating. In this way, at EndeF we began to use our own terminology to designate these models, classifying them by “generations”; This terminology, today, is the most widespread in the sector.

    The jump from one “generation” to another is marked according to the insulation degree that the panel itself has and the covers it incorporates. We can differentiate between:

    – 0 Generation Hybrid Solar Panels (PVT-0)

    It is the primary and most basic model on the market for hybrid solar panels; the first hybrid solar panel created. This panel is simply composed of photovoltaic cells, a heat absorber and a junction box for electrical wiring. It does not have insulation on either side, so the temperature it can reach is much lower.

    Given these characteristics, the location where these panels are usually installed are swimming pools since water is required at a lower temperature than, for example, in a home.

    – First Generation Hybrid Solar Panels (PVT-1)

    In this panel, a rear cover is added to the junction of the photovoltaic laminate and the thermal collector whose function is to conserve heat, thus preventing it from being lost through the rear of the panel.

    The cover only at the rear makes that, among other things, the photovoltaic laminate is not so hot, thus enhancing the electrical part of the panel. These panels work at a lower temperature than hybrid models with a front cover, being ideal for hot places and, especially, the locations where what is intended to be enhanced is the photovoltaic part.

    It is currently the most widely sold hybrid solar panel in the world.

    – Second Generation Hybrid Solar Panels (PVT-2)

    The main feature of these panels is the incorporation of a transparent front cover. With this, it is possible to alleviate what for some is the main drawback of hybrid solar panels from previous generations: heat loss through the front face.

    Thus, by isolating the panel itself on both sides, an even greater decrease in heat losses is achieved and, therefore, a considerable increase in the thermal performance of the panel. By reducing both heat losses, this panel is postulated as ideal for places with a cold climate and, above all, where what is intended is to enhance thermal production.

    Given this, the same question always arises: How to decide between one model or another?

    • If you want to install in a hot place and/or you intend to enhance the electrical part: 1st generation hybrid solar panel.
    • If you want to install in a cold place and/or intend to enhance the thermal part: 2nd generation hybrid solar panel.

    Hybrid Solar Panel ECOMESH

    At EndeF we are aware of the need to innovate that the solar energy sector requires of us and that is why we work on this line 24/7. With RD as the hallmark and our hybrid solar panel ECOMESH as the flagship, at EndeF we know that the constant improvement and adaptation of these panels is very important for their subsequent (and now, real) implementation.

    Do you want to know more about the most efficient solar panel on the market? ¡Meet ECOMESH!

    CTA Technology

    The inclusion of CTA technology (Transparent Insulating Cover), patented by EndeF, makes ECOMESH a more efficient hybrid solar panel than those already on the market. This technology encourages panel performance to increase in two ways. Regarding the photovoltaic part, the fact that the water circulates inside the panel makes the photovoltaic cells cool so that, when working at a lower temperature, the electricity generated is greater. Regarding thermal production, the CTA technology and the inert gas that it incorporates improve the efficiency of the panel.

    Characteristics of the Hybrid Solar Panels ECOMESH

    The ECOMESH hybrid solar panel has substantial advantages that make it a really interesting product, especially for those locations where space on the roof is limited. It is because the collection surface necessary to generate the same energy as separate photovoltaic and thermal panels is reduced by 40%.

    In addition, due to the greater efficiency that CTA technology provides, thermal production is three times higher than what first-generation hybrid plates can generate at high temperatures.

    Regarding the photovoltaic part, in the same way, in warm places the production of electricity can be up to 15% more than that achieved by conventional photovoltaic solar panels.

    Developed and manufactured in Zaragoza (Spain), the ECOMESH hybrid solar panel, by combining the two technologies in a single module, guarantees the best results per unit area.

    Where is it possible to install a hybrid solar panel?

    Although it is true that the installation of hybrid solar panels is ideal in those places where the surface area on the roof is small, any place is a good location for this product. In addition, these facilities receive special interest the greater the demand for domestic hot water (DHW).

    Considering these two circumstances, the most recommended places to install this new technology are:

    • Hotels
    • Senior residences
    • Residential buildings
    • Sports centers
    • Hospitals and clinics
    • Car washes
    • Industry

    In addition to all of them, and despite the fact that energy consumption is not so high, single-family homes are also presented as a possible scenario for hybrid solar panels.

    If you want more details about the possible applications, do not miss all the information about it through the following link in ECOMESH

    Some places where ECOMESH hybrid solar panels are already operating

    EndeF has carried out different projects in which the presence of the functioning ECOMESH hybrid solar panels is already a reality. Whether we’ve installed them directly or through an approved installer, many places are already enjoying the clean power generation and energy savings (and therefore economical) that this provides.

    Here we leave you some images from some of the installations of the second generation hybrid solar panel ECOMESH:

    In order, from left to right, the facilities shown here correspond to:

    • Parque de Bomberos 1 (Zaragoza), the first hybrid solar installation carried out in Spain in a public building.
    • Single-family Home.
    • Great luxury hotel in the Balearic Islands.
    • EndeF roof.

    As you can see, the owners of these and many other installations are already enjoying hybrid solar energy thanks to the ECOMESH solar panels.

    The future of the Hybrid Solar Panels

    Although, as we already said at the beginning of this entry, the hybrid solar panel is a product that has been existing for many years, the advances that it is having are going at a dizzying pace with the aim of further implementing them in all types of buildings. That is why, beyond the own RD investment that companies like EndeF carry out year after year, a joint effort is required by all the actors involved in the development of this technology.

    That is why, increasingly, different activities and events are organized where hybrid solar panel manufacturers from around the world meet to talk about sensations, experiences and advances that help the sector take off. Among these activities, Task 60 stands out, framed within the “Solar Heating Cooling Program”, where we have the enormous privilege of participating together with the rest of our colleagues in Europe.

    If after reading this entry, you still need more information, EndeF remains at your entire disposal; Our technical department will be happy to assist you and answer any questions you may have.

    ¡See you soon with a new entry of: “Solar Energy For beginners”!

    Hybrid Solar PanelsPower, Heating and Cooling!

    Hybrid solar panels can mean different things to different people. New technologies with layering of photovoltaic elements can make panels more efficient than conventional designs. I intend to look at these more under some of the solar research pages as most of the technologies are still at that level.

    Another view is that a hybrid panel combines photovoltaic electricity creation with hot water production usually for water heating. In doing so efficiencies of the panels rise dramatically to 75%. a great result in any way of looking at extracting the sun’s energy for our use.

    There are a number of companies exploring these very useful technologies. One is standing head and shoulders above the crowd at the moment.

    Images on this page courtesy of Chromasun

    In the laboratory single layer photovoltaic technology has produced 28.3% efficiency with single-junction Gallium Arsenide solar cells. Multi-junction ones, with concentrated light applied, have achieved 43.5% efficiency.

    In commercial applications being used at present, though, actual efficiencies range from 10 to 18%. Not a great result especially when considering the area panels will have to cover to produce effective power. As well as the consumption of the substrates in panels at that size.

    Efficiency of conversion falls with increasing temperature of the panels. Above 42oC there is a cumulative 1.1% loss in efficiency for every 1 degree rise in the panel’s temperature.

    A number of companies have attempted to overcome this. By having cooling coils under the panels, heat can be conducted away, often utilizing water. This heated water can then be used for further household and commercial purposes.


    One such company, a Turkish origin one, now operating in Europe, Solimpeks has produced flat panels with a drum at the top end to contain the heated water. Reaching 150oF the water can be used directly. Panel efficiencies are said to reach 28%.

    Sundrum Solar

    A similar style panel being produced in the US by Sundrum Solar is said to create efficiencies of 60-70%.


    Another US company, Cogenra, claimed their system increased energy utilisation by five times over usual photovoltaic panels. Their company was bought out by SunPower. so far there is no sign they are marketing a hybrid product.


    SunScience Corp in Reno, Nevada began a pilot project with hybrid solar panels producing power and hot water aimed at the agricultural market. The panels allow growing of crops outside of usual seasonal periods. The first winter-grown crops were ripening in January 2012.

    Joint Research

    Another strategy pursued was joint research between Columbia University and a structural and mechanical engineering firm, Weidlinger Associates, seed funded with 150,000 from the Department of Energy.

    With the aim developing a roofing tile that could be used to generate solar power they had a type of hybrid solar panel composed of multiple layers. With a top layer plastic coating, a photovoltaic panel situated beneath it, and a further layer of fine tubes below to heat water, at the same time cooling the PV panel above. Further layers to support the structure underlay these.

    Expected energy efficiencies were only of the order of 12%. Once the design had been proven further more extensive funding was expected. There does not seem to be further information on this project, suggesting the initial pilot was not too successful.

    Sun Shot Program

    Through the US Department of Energy, the Nobel Prize-winning current US Energy Secretary, Steven Chu has established the Sun Shot program. Its aim, with a couple of hundred million dollars a year funding, is to produce efficiencies in solar production to make it a viable alternative energy.

    In Arizona, with its high sun exposure, solar power can now be produced at 10c a kilowatt hour, and in Europe at about twice that. Steven Chu would like to aim for 6c a kWh to achieve parity with other sources of electrical power.

    Mirroring the effort behind the Moon shot, Sun Shot has a goal to achieve this level of efficiency by 2020! Hybrid solar panels would go a large way to achieving this. The FOCUS with Sun Shot though seems more on improving photovoltaic efficiencies.

    Duke University

    A variation on hybrid solar panels is research work being undertaken at Duke University. There Nico Hotz has been developing panels of copper tubes internally coated with aluminium and aluminium oxide. Water and methanol circulates in the tubes. Heating this mixture to 200oC and adding a catalyst, yields hydrogen which can then be stored in fuel cells for later energy use.


    Another research project, this time at MIT, aims to FOCUS solar energy by parabolic mirror onto tubes to heat water. This should then either drive turbines or by a thermocouple process, with the varying temperatures within the tubes, produce electricity. It was at the computer modelling stage by the end of 2011.

    Zenith Solar

    As a similar concept in using parabolic mirrors is an Israeli project by ZenithSolar Ltd set up as a solar farm around April 2009.

    The energy generation part of these sun-tracking hybrid solar panels is a central 10cm unit at the mirror focal point with a photovoltaic panel and heat conversion unit. Calculated to achieve 76% efficiency each panel should produce 15kW combined electrical and thermal generation at 8.6c a kWh.

    The panels were expected to cost around 29,500 each by the time they are available for residential and commercial applications.

    Greenearth Solar Energy

    An Australian company, Greenearth Solar Energy Pty Ltd, has signed a distribution agreement with ZenithSolar Ltd to introduce the panels into the Australian market.

    Chromasun Enters Hybrid Solar Panels

    Into all this innovation walks an Australian, Peter L Lievre, who had been developing systems in his own country in association with the Australian National University and University of New South Wales.

    Looking for an environment to further his research as well as being closer to development finance he settled in Silicon Valley.

    His company, Chromasun, has been installing commercial high-efficiency unique solar thermal units for some time.

    With special Fresnel mirror directed sunlight reflection onto tubes at the top of the panels, the collecting fluids heat up to 400oF, 204oC. Whether water or another suitable fluid, this can be used to heat water for commercial and other uses or also to drive cooling units developed for the panels. Huge airconditioning benefits can be achieved.

    In 2007 Chromasun installed hybrid solar panels for testing and data collection at Santa Clara University in San Jose, California. Successful results with added photovoltaic electricity generation meant the units achieved an efficiency of 75%.

    Known as the MCT Hybrid. for Micro-Concentrator. these new hybrid solar panels are now available for commercial and residential applications. Only a few panels are required to provide complete power for a home. This includes electricity, hot water and cooling requirements.

    The future for hybrid solar panels looks bright with much more efficient use of the abundant energy the sun sheds on the earth each day.

    Hybrid Solar System: Working, Price, Types, Pros, and Cons

    Hybrid solar systems produce usable electricity with the help of hybrid solar inverters and batteries. The power stored in the batteries can be used later on.

    These Hybrid solar systems work in the same manner as traditional grid-tied solar systems. But since they can also store energy, most hybrid systems can function as a backup power source too.

    They can provide continuous energy even when there is a power outage.

    Intriguing, isn’t it? Dive in to learn more about the components, prices, and types of hybrid solar systems.

    What Is A Hybrid Solar System?

    Solar power systems come in three varieties; on-grid, off-grid, and hybrid. A hybrid solar system has the good features of both on-grid and off-grid solar systems, minus their flaws.

    The hybrid solar system is connected to the grid via net metering and also has a battery backup to store the power. The energy that solar panels collect goes through a hybrid solar inverter to generate electricity.

    The most important benefit of a hybrid solar system is the power backup facility. It means you can continue using electricity without disruptions even during power outages. A battery backup helps store the extra power generated by the solar system during peak hours.

    • – A hybrid solar inverter is used more than a standard battery inverter in a battery-ready system.
    • – The modern hybrid solar inverter comes with a charger and a built-in connection.
    • – Owing to its benefits, a hybrid solar inverter is naturally more expensive than a standard battery inverter.

    Components In Hybrid Solar System

    The hybrid solar system has four elements:

    hybrid, solar, panels, energy, beginners

    Solar panels are used to convert solar energy into DC electricity. The solar panel is an essential component of the solar system.

    It is the second important component in a solar system. The hybrid inverter regulates the voltage and converts DC to AC voltage which can be later used to power household appliances.

    The direct current delivery box has a fuse, SPD, and MCB for security. The DCDB connects multiple solar panel wires into a string with positive and negative outputs.

    The charging controller enhances the battery life by controlling the quantity of power going inside the battery.

    Types Of Hybrid solar inverters

    The most cost-effective hybrid solar system employs a basic inverter which includes a hybrid solar inverter and a charger. It also comprises Smart controls for the most efficient use of the provided electricity.

    hybrid, solar, panels, energy, beginners

    There are four main types of hybrid solar inverters;

    • – Basic hybrid solar inverter
    • – Multimode hybrid solar inverter
    • – All-in-one Battery Energy Storage System (BESS)
    • – Advanced AC coupled system

    Basic hybrid solar inverter

    This is the most common type of hybrid solar inverter that allows storing solar energy in a battery. However, it cannot be reliable during power cuts because it is not connected to a grid system.

    Multimode hybrid solar inverter

    This is an advanced hybrid solar inverter with a built-in backup or a separate unit. You can charge the batteries and use them during a power cut.

    All-in-one Battery Energy Storage System (BESS)

    The BESS is the new hybrid solar inverter with batteries and the inverter. This system can be adapted to any existing solar system without any difficulty.

    Advanced AC coupled system

    AC coupled systems are widely used solar batteries. They have a hybrid solar inverter for charging the battery. These rechargeable batteries are simple to use; however, they are less efficient than their DC-coupled system. AC coupled systems are used to power AC loads, and the efficiency can be expanded by using multiple hybrid solar inverters.

    Advantages Of Hybrid Solar Inverters

    • – A hybrid solar power system comes with batteries. This provides an uninterrupted power supply even during a power outage.
    • – Solar power connected to a battery system ensures the maximum use of solar energy; thus, saving a lot on your electricity bills.
    • – Compared to conventional energy sources, a hybrid solar inverter does not require routine maintenance because it does not use gasoline.

    How Does A Hybrid Solar System Work?

    A hybrid solar system is reliable because it supplies constant electricity. Below are steps that explain how this system works:

    • – The panels absorb the sun rays during the day, converting them into electricity and storing the excess energy in the batteries. If any extra energy remains after using the required power, the excess amount is sent back to the grid via net metering.
    • – The batteries are rechargeable. If the power is cut for too long, the batteries can be recharged from the grid.

    Hybrid Solar System Cost

    A hybrid solar system is more expensive than conventional on-grid and off-grid systems. However, investing in a hybrid solar system reduces your electricity bills and supplies interrupted power supply.

    The price of a 1kW hybrid solar system in India is expected to be around ₹ 1,00,000. It can also go up to ₹15,00,000 for 20kW.

    However, the vary depending on the quality, manufacturers, availability, etc. So, no one price line can be drawn. will also vary from seller to seller, model to model, and installers to installers.

    Solar Diesel Hybrid System

    The solar-diesel hybrid system is a combination of photovoltaics and diesel gensets. The diesel gensets are utilised in bridging the gap between the load of the system and the electricity provided by the photovoltaic system.

    Advantages of a solar-diesel hybrid system:

    • – It helps store the energy generated during the day and can be used whenever needed.
    • – The system provides a non-stop power supply even when the grid fails, or the PV cells produce less energy.
    • – The maintenance and operations cost of a solar-diesel hybrid system is low.

    Solar PV Wind Hybrid System

    The solar PV wind hybrid system uses wind as the main source to generate electricity. However, this system is not as effective as the other solar systems. It has to be combined with other energy sources to ensure continuous power generation.

    Solar Thermal Hybrid Systems

    These solar systems are not only used for generating power but also for heating purposes. The lifespan of the Solar Thermal Hybrid System is approximately 20 to 25 years old. The efficiency of this system is better than most other conventional systems.


    The popularity of Solar energy is likely to grow in the next ten years. Solar energy is a renewable form of energy, making it highly beneficial. That being said, it is essential to know the benefits of each solar system to invest in the right one.

    The hybrid system saves money, and the most excellent feature is the battery backup feature, which ensures you don’t run out of power.


    Q1. What is the shelf-life of a hybrid solar system?

    Hybrid solar power systems typically last for around 10-15 years. However, they can last up to 20 years if proper care is taken.

    Q2. What is the lifetime of a solar inverter battery?

    hybrid, solar, panels, energy, beginners

    A solar inverter battery can last up to 4 to 5 years. These batteries require regular maintenance.

    Q3. Is investing in a hybrid solar system worth it?

    Hybrid solar systems are ideal solutions to reduce your electricity bills. They also supply uninterrupted power supply.

    What Is Hybrid Solar System? | Hybrid Solar System Connection | Components of Solar Hybrid Power Systems

    After installing solar panels, energy generated from them needs to be converted into electricity for your home. This is a few ways to do this; you can stay connected to the grids, go completely off-grid, or have hybrid systems. Hybrid systems are when your solar panels are connected to the grid’s power lines and have a backup battery system to store the excess electricity.

    The sun’s energy absorbed by solar panels goes through an inverter to create usable electricity. From there, the electricity goes to either your home, your battery, or the grid. The advantage of a hybrid solar system is that you will always have electricity in any case.

    With a backup battery, the extra energy that your solar panel makeup but your home doesn’t use will be stored in this battery. Then, when the sun isn’t shining, this battery will power you through the night during system blackouts or inclement weather.

    With a hybrid solar system, if you use all of your battery power, you have the ability to draw powers from the electrical grid. A hybrid solar system works by sending solar power to your inverters, which then send energy to power your home. Excess energy that isn’t used to power your home goes to your home’s battery for storage. This battery can power your home when your solar panels are not producing energy.

    After all those steps, if there is still energy left, that energy is sent to the grid. The hybrid solar system is a crossover between grid and off-grid solar systems. This gives the advantage of being connected to the utility grid at the same time and giving your home enough backup to power significant loads in the event of blackouts.

    The basic idea behinds hybrids solars are that when the sun is shining, you generate electricity from your solar panels and store this power in a battery. Once your battery is fully charged, you will use the excess electricity from solar to power your home appliances, and if any more electricity is left, it will be exported to the utility grid.

    The power stored in your battery will be used when your utility grid is turned off as source of power backup. Hybrids solar systems give you all the benefits of a grid-tied system while providing power backups in the event of powers outages.

    In the event of a powers outage, the on-grid solar system shuts down. Solar panels and batteries alone don’t help generate electricity, and you also need other components that will help generate electricity.

    Hybrid Solar System Connection:

    Hybrid Solar System Working When There Is Power Outage:

    If there is a powers outage in the early morning or afternoon when the sun is shining and your solar system is generating electricity, your solar system will not shut down as it does in an on solar grid system, but it will turn itself off. Will disconnect from the grid will continue. ,

    The amount of electricity your home will need during a power outage will be drawn from the battery. Let me tell you one thing if your solar system is of 3 kW and you are running more than 3 kW of appliances on it at a time when the grid goes down, then your inverter will shut down.

    Components of Solar Hybrid Power Systems:

    #1. PV System (Primary Power Source)

    A PV system consists of several PV modules and panels that form a complete photovoltaic power generating unit. Their panels absorb the sun’s rays convert the received energy into electricity. In other words, they convert solar radiation energy into direct current.

    #2. Energy Management System (EMS)

    It is a system that is responsible for monitoring the power demand as well as the rate of power generation at primary power sources to ascertain a consistent power output by simultaneously charging the supplementary power source as and when required.

    Can you batteries or use them when appropriate. One of the advantages of using the EMS is that they can be configured based on various user preferences based on monitored system parameters.

    #3. Solar Inverter

    The direct current produced by the PV systems is not so useful. Solar inverters are used to convert the DC output of a photovoltaic panel into a good 240v alternating current (AC) output.

    #4. Battery

    Batteries store the excess generated energy for later use when there is not enough PV production or in cases where both the PV and the supplementary power source cannot produce enough energy to meet the power demand from the systems.

    Solar Diesel Hybrid System:

    As previously mentioned, solar-diesel hybrid systems couple photovoltaics and diesel generators, also known as diesel gensets. Diesel gensets are intended for these systems for fluctuating solar power generation, and there will be battery storage as well as an energy management system to increase the overall efficiency of the system, which will allow for the ups and downs of solar power and diesel Genset operation.

    Than monitors. Distance from its power output limit, so as to decide when to charge the battery or use it for continuous power generation. Instead of connecting the solar system to the power grid, the use of diesel gensets in a solar hybrid power system will most likely occur when the grid strength is poor, and there are frequent power outages.

    For all hybrid power systems, there is one main energy supplier. For this case, the main power system can be either a diesel power generator or a solar PV. In the first scenario, the goals are to reduce fuel expenditure by adding additional energy from the photovoltaic systems.

    In scenario second, which is the actual purpose of these posts, diesel gensets are intended to compensate for energy output fluctuations of solar PVs with batteries and an energy management system to optimize both fuel efficiency and power generation stability.

    There are several benefits to consider for a solar-diesel hybrid power system. The excessive power output will be stored in batteries for later use or may even be sent to the power grid.

    However, with proper selection use of equipment, all energy can be used without being wasted or put back into the grid. The use of diesel gensets with batteries for these power systems ensures continuous and uninterrupted power generation, even if the PV generation is not sufficient or the grid fails.

    In addition, these systems are certainly more environmentally friendly than systems that rely solely on fossil fuels for electricity generation due to their emphasis on the solar part of power generation and producing fewer pollutants such as carbon monoxide the way systems rely only on fossil fuels.

    Solar PV-Wind Hybrid Systems:

    The other important types of the solar hybrid power system are the solar PV-wind hybrid power system, in which the supplementary power source is wind. This is a really good combination as both solar and wind are among the renewable energy sources.

    Another cool thing about interconnecting wind and solar power systems is that typically the peak of solar power occurs when the wind is not so strong, and the wind peak operating time is when the wind is not so strong. Energy is negligible or at least weak.

    This means that these systems are inherently less volatile in terms of power output. Wind power systems and solar power systems individually are not as effective as their combination because there are times throughout the year when wind or solar power is not available as much as is needed.

    Therefore, solar-wind hybrid power systems may be a better choice for continuous power generation. They can also be integrated with another supplementary power source such as diesel to guarantee consistent power output. Well, any hybrid power system requires the use of batteries, and these hybrid power systems are no exception.

    Solar Thermal Hybrid Systems:

    Solar hybrid power systems of the solar thermal type are slightly different from the previously mentioned solar power systems. These power systems are not only used for electricity generation, and as the name suggests, they are used for electricity generation as well as heating.

    It is clear that a portion of the power generation will be devoted to heating for any power system, but these systems will separate the heating portion from the power generation portion and are, therefore, more efficient than other power systems. The logic behind their design is quite fascinating. Well, you can expect your photovoltaic cells to reach 20% electrical efficiency, which means they can only convert the Sun’s radiation into electrical energy.

    However, about 65% to 70% of that radiative energy of the Sun will be converted to heat, raising the temperatures of the PV module. These hybrid systems are designed to absorb heat using components called PVT collectors to make better use of the solar spectrum.

    Since these systems are designed to direct the heat absorbed from system surface areas towards heating purposes, where necessary, the surface temperature of the modules will be reduced, meaning their lifetime will be extended. Well, it certainly increases the overall efficiency of the system but will reduce the efficiency of the solar collector due to the low surface temperature.
