    Solar Panels

    A solar panel is a device which is an arrangement of multiple solar cells, which are connected in parallel or series alignment to observe sunlight and then generate direct current (DC). It is also known as Photovoltaic (PV) module, सोलर प्लेट or सौर ऊर्जा. There are seven main components of a solar panel which are combined to make a single PV module. Photovoltaic has two words in it, in Latin language ‘photo’ means ‘light’ and ‘voltaic’ means ‘electricity’, which defines electricity generated from light.

    What is Solar Energy?

    Solar energy is the light, and heat radiated from the Sun. On earth, to have the existence of human life, along with, oxygen and water. heat light become essential and the source of these is the sun. The nuclear fusion reaction happening on the sun has been the reason for the heat light it has been generating for millions of years.

    Sunlight takes about 8 minutes and 20 seconds to reach the earth’s surface, the distance is about 149.22 million Kms. The photons emitted from the surface of the sun travel this long distance to reach earth. So, the actual location of the sun that you can see is about 8 mins and 20 seconds earlier.

    How is Solar Energy Produced?

    The solar PV modules help a generation of solar energy; however, it can’t be used in its raw form as the panels tend to produce the DC – direct current- a flat linear output and a tendency of lots of transmission losses. Also, all household equipment use AC- alternating current, a sinusoidal wave.

    In this scenario, the conversion of DC to AC is very important, for which an inverter is needed. Further, based on the need of requirement, we can then add as many components as possible including rooftop solar to generate electricity.

    How do solar panels work?

    Many consumers want to know how solar panels work. So, we have taken in- depth knowledge about this topic. According to ResearchGate research website, Amount of energy in the form of heat and radiations called solar energy. Shown in Fig.1. It is radiant light and heat from sun that is natural source of energy using a range of ever changing and developing of technology such as solar thermal energy, solar architecture, solar heating, molten salt power plant and artificial photosynthesis. The large magnitude of solar power available makes highly appealing source of electricity. 30% (approx.) solar radiation is back to space while the rest is absorbed by ocean, clouds, and land masses.

    PV cells Convert Sunlight to Direct Current (DC) electricity. Solar Inverter or Charge Controller work as control the power from solar panel which reverse back to solar panel get cause of panel damage. Battery System act as storage of electric power is used when sunlight not available (i.e., night). From this system connected to inverter for convert Direct Current (DC) into Alternating Current (AC). Figure 2

    The cells converted solar radiation directly into electricity. It consists various kinds of semiconductor materials. It has two types: positive charge and negative charge shown on fig.1.This cell technology are used to design solar cells with low cost as well as high conversion efficiency. When the cell absorbed photons from sunlight, electrons are knocked free from silicon atoms and are drawn off by a grid of metal conductors, pressure a flow of electric direct current. Solar cell PV made up of many chemicals.

    The solar panels generate DC power during the day whenever adequate solar radiation is available. This DC power is maximized by a MPPT Charge Controller unit. Part of it is directly fed to an AC load though a charge controller (DC to DC converter) and an inverter, while the remaining power is fed through the charge controller to the battery bank and stored. It is withdrawn from the battery bank when required (usually when adequate solar radiation is not available in the day light hours) and fed to the DC-DC converter. The DC-DC converter is in turn connected to an inverter and the resulting AC power is connected to the load. Read more here: https://www.loomsolar.com/blogs/collections/how-do-solar-panels-work

    How many types of solar panels are available in India?

    There are generally three types of solar panels, ‘ Polycrystalline solar panels, Monocrystalline solar panels, and Bifacial solar panels’ that are available in the Indian solar market.

    CleanTechnica Tested: The EcoFlow DELTA 2 Max Solar Generator

    EcoFlow seems to be on ‘a can’t stop, won’t stop’ mission to transform not only the world of portable solar generators, but is also starting to develop a host of appliances that take advantage of these portable power sources.

    Following on the heels of a successful lineup of portable power stations and solar panels, EcoFlow has introduced the DELTA 2 Max portable power station. This two kilowatt-hour unit packs a punch with its ability to push out nearly 2,800 watts of continuous AC power output.

    We pushed this thing harder than we had pushed any portable power station we’ve tested, and it simply refused to die. With 2,800 watts of AC power output capability, it can easily power just about any appliance in the house, including power tools, 110 volt welders, and EV car chargers, in addition to the usual assortment of refrigerators, cameras, drones, and the like.

    Charging The EcoFlow DELTA 2 Max

    The EcoFlow DELTA 2 Max is well equipped to pull power in and push it back out again. When plugged into an AC wall outlet, it can absolutely gobble the power down. It features a choice between slow charging at around 400 watts, or fast charging at up to 1,800 watts. Recharging in fast mode translates to about an hour and a half for a full charge, with the charging speed tapering off as the battery pack fills up.

    When pulling down 1,800 watts of power at a time, the cables to the wall start warming up, and it’s especially important to be sure you’re using the cable supplied by EcoFlow, as the cables made by mere mortals won’t likely hold up to this amount of power draw for very long.

    EcoFlow has also continued to build out its array of solar panel options, and sent along its 220 watt bifacial folding flexible solar panel for us to test. This is the first portable folding bifacial panel we’ve seen, and sandwiches the bifacial solar cells between two layers of clear durable plastic.

    Bifacial solar panels still produce the majority of their electricity from sun hitting the top of the panel. This means the panel itself is directional, and as such, it is important to ensure that the side labeled as “sun facing” should be oriented appropriately. This is the side with the wires coming out of it, which is a bit confusing, but the cables have plenty of length to make it work with minimal fuss.

    The back side of the panels harness light reflecting up from the back of the unit. This is helped along by the stand for the panels, which doubles as the padded case for the unit. The inside of the stand is a bright white surface, which helps reflect some of the light passing through the panels and from nearby areas back up to the rear of the solar panel. In our testing we did see production over 200 watts, although it was difficult to achieve on the grassy surface we tested it on. It performed slightly better on lighter colored cement, which is in line with EcoFlow’s estimates in the image above.

    Discharging

    We spent an entire day using this as the power source for our heat gun as we vinyl-wrapped a car, running the heat gun, music, and our devices off of it. The realization that these portable power stations can not only be used when the power goes out, but also as portable power sources in the home for situations where an extension cord would normally be needed was eye-opening. It almost felt like it was bopping along with the music as we worked. Granted, our heat gun only pulled between 500 and 900 watts, depending on the temperature and throughput volume, but that was just the start.

    We ran it through the normal gamut of kitchen appliance tests, ranging from our 800 watt kettle up to the full complement of 1,500 watts worth of blenders, mixers, and kettles, and again it hardly noticed. The EcoFlow DELTA 2 Max boasts 6 AC outlets on the rear of the unit, as well as two 12 volt, 3 amp barrel connectors, and a standard 12 volt automotive outlet. On the front of the unit, four USB-A outlets and two USB-C outlets make it easy to charge all your devices without the need for an extra AC adapter.

    We ran a small automotive refrigerator unit from the 12 volt barrel outlet, and pulling between 5 and 55 watts depending on whether the compressor was running or not, the EcoFlow DELTA 2 Max kept up without missing a beat. This is a minor task in terms of output, but mirrors real world scenarios customers will likely use it for.

    It’s easy to imagine this unit being put to task as a backup power station for a home. Granted, with just two kilowatt-hours of storage capacity, you’ll need to tightly manage how much power you’re pulling. With 2,400 watts of continuous output and a staggering 4,800 watts of peak power output, this unit would have no issue supporting a compact tiny house or RV setup by itself. Adding in a solar panel or two further extends that capability.

    Overall

    The EcoFlow DELTA 2 Max is an extremely capable portable power station, though it is a bit on the heavy side at 50 pounds. That calls into question the portable nature of the unit, though. With something of this size, it’s likely you’re not going to be moving it around a whole lot. That holds true for most large battery systems, as their weight and the relatively fragile nature of the battery cells themselves makes it a good idea to leave them stationery as much as possible.

    The EcoFlow DELTA 2 Max is 1,899, which is a slightly higher price than most of the competition in the portable power station space. EcoFlow currently has the DELTA 2 Max on sale and is currently including two 110 watt solar panels free with purchase. That definitely helps the value proposition, but it’s still a premium unit and is priced as such.

    Placa solar bifacial ¿Cuáles son sus características y ventajas?

    La energía solar que recibimos en la tierra es abundante, incluso no podemos llevar a aprovecharla, sin embargo la nueva tecnología y avances ha ayudado para la creación de un panel solar que permita tener un doble aprovechamiento y es la placa solar bifacial.

    Las placas bifocales son un tipo de tecnología emergente el cual ha ganado popularidad debido a la forma innovativa con la que aumenta el desempeño de un sistema de paneles fotovoltaicos. Esto es esencial para poder bajar los costos de electricidad generados en plantas fotovoltaicas.

    A pesar de que este tipo de sistemas empezaron a ser desarrollados en los años 60, solo se empezaron a comercializar recientemente gracias al desarrollo de tecnología más barata.

    ¿Quieres conocer más sobre la placa solar bifacial? En este blog veremos qué son, cómo se diferencia de las convencionales, sus ventajas, cuando es recomendable usarla, y mucho más.

    ¿Qué es una placa solar bifacial?

    Los sistemas fotovoltaicos bifocales, también llamados placas solar bifacial, son una alternativa innovadora que puede reducir los costos de generación.

    Una placa solar bifacial produce energía eléctrica en ambos lados del panel. Mientras que los módulos fotovoltaicos tradicionales son mono faciales, es decir, que solo producen energía de un lado del módulo, los módulos bifocales pueden generar energía al estimular ambos lados del módulo.

    ¿Cómo se diferencia de las convencionales?

    Las placas bifocales funcionan de la misma manera que las convencionales, aprovechando el efecto fotovoltaico para generar una corriente eléctrica al exponer un semiconductor a la luz.

    En comparación con las placas solares convencionales, una placa solar bifacial puede absorber luz en la parte trasera de la placa.

    Cabe señalar que la luz solar puede reflejarse en todo tipo de superficies no reflejantes. La luz rebota de estas superficies y llega a la parte posterior del panel, convirtiéndose en energía eléctrica. A este fenómeno se le conoce como albedo.

    Ventajas de las placas solares bifocales

    Una placa solar facial funciona de la misma manera que una convencional, es decir, por el efecto fotovoltaico, a pesar de esto cuenta con sus ventajas y algunas desventajas, a continuación te las explicamos.

    Mayor Eficiencia

    Como mencionamos anteriormente, las placas solares bifocales producen más energía eléctrica comparado con las placas solares tradicionales. Esto se debe a la absorción de luz que ocurre en la parte posterior del panel fotovoltaico.

    Incluso, las celdas solares bifocales pueden aumentar la ganancia de carga generada entre un 13% y 35% de energía adicional comparado con los modelos tradicionales bajo cielos despejados.

    Mejor Resistencia

    Generalmente, las placas bifocales no están fijadas a un marco, sino que están cubiertas en ambos lados por vidrio templado.

    Este vidrio templado es sumamente resistente al clima, la luz ultravioleta y las altas condiciones de temperatura y clima. Por lo tanto, los paneles bifocales tienen vidas útiles más largas comparado a los paneles tradicionales.

    Menor degradación inducida por potencial

    La degradación inducida por potencial es un fenómeno que ocurre cuando se genera una gran diferencia de potencial entre el semiconductor y otras partes del módulo, como el vidrio y el marco del panel. Esta diferencia de potencial genera una fuga de corriente, es decir, permite la migración de iones positivos y negativos entre ambos extremos.

    Este flujo de iones contamina el semiconductor, reduciendo el efecto fotovoltaico que ocurre en el módulo y conduciendo a pérdidas de energía de hasta el 20%. Ya que las placas solares bifocales no requieren de un marco de metal, se vuelve muy improbable que el semiconductor se pueda degradar.

    Este fenómeno es menos común en la placa solar bifacial que en las convencionales.

    ¿Cuándo es recomendable usarla?

    Una placa solar bifacial funciona mejor cuando están instalados en espacios amplios con mucha radiación solar, de manera que la parte posterior del panel pueda capturar energía solar y generar energía eléctrica. Por lo tanto, sólo se recomienda instalarlos en parques fotovoltaicos grandes con mucha incidencia solar.

    Cabe señalar que existen algunas opciones en las cuales se pueden usar los paneles solares bifocales en zonas urbanas. Particularmente, se pueden instalar en estructuras de pie que den sombra parcial pero que sean lo suficientemente altas como pabellones, cocheras, toldos y pérgolas.

    La realidad es que estas zonas son muy limitadas, por lo que lo más recomendable es espacios amplios que no tengan impedimento para la luz solar.

    Conclusiones

    Las placas solares bifocales son una alternativa innovadora para reducir el costo de la energía en proyectos fotovoltaicos y puede ser más eficiente que la tecnología solar convencional.

    Sin embargo, este tipo de tecnología no son prácticas en zonas urbanas a menos que sean instaladas en construcciones altas que permitan el albedo.

    Trina lanza un módulo de 600 W

    El gigante chino se ha adelantado a sus rivales, que recientemente anunciaron su intención de trabajar en la próxima generación de megapaneles y se compromete a poner a la venta su producto Vertex de 600 W a finales de marzo.

    El nuevo módulo de 600 Wp de Trina.

    Cinco meses después de lanzar su primer módulo solar de más de 500 W, Trina Solar ha revelado una serie Vertex de nueva generación que, según dice, puede generar hasta 600 W.

    En una conferencia de prensa celebrada por la empresa en su sede de Changzhou el jueves, el jefe de estrategia y gestión de productos Zhang Yingbin dio detalles de una serie de paneles que incluye dos productos para clientes internacionales: un modelo bifacial de células de 6×10 que, según ha afirmado, puede generar hasta 600 W, y un dispositivo de 5×11 de 550 W, también bifacial.

    “Los módulos Vertex de próxima generación optimizados con una serie de avanzadas innovaciones, incluyendo una oblea de silicio de 210 milímetros, empaque de alta densidad y tecnología de barras colectoras múltiples, ofrecen una eficiencia de conversión fotoeléctrica de más del 21 %. Gracias al bajo voltaje y a la alta potencia de salida de la cadena de módulos, la nueva serie Vertex abre un enorme potencial para reducir aún más los costos de equilibrio del sistema”, dijo Zhang.

    El Vertex tiene un voltaje de circuito abierto más bajo de 41,7 V y una corriente elevada de 18,4 A, según Trina. La potencia disponible para los proyectos solares podría aumentar hasta un 41% para los desarrolladores que utilizan el Vertex, según el fabricante, que fija un ahorro asociado el producto de 0,1 RMB/W (0,014 dólares), gracias a la necesidad de menos cables, cimientos, bastidores y otras infraestructuras. Eso impulsaría un coste nivelado de reducción de energía del 2-3%, dijo Trina.

    Zhang dijo que la compañía con sede en Changzhou comenzará a producir el Vertex de 550 W este año, y la versión de 600 W se espera para el primer trimestre del próximo año. Trina dijo que tendrá 10 GW de capacidad de producción anual de Vertex este año, aumentando a 21 GW el próximo año y 31 GW el año siguiente.

    Fijar la fecha de disponibilidad en el mercado para el modelo Vertex más potente en el primer trimestre del próximo año desmarcaría a Trina de sus rivales, con quienes formó la Alianza Ecológica de Innovación Fotovoltaica Abierta de más de 600 W este mes con el objetivo de producir el siguiente nivel de módulos ultra potentes.

    El Vertex también reforzaría las afirmaciones de la oblea de silicio de 210 mm aprobada por Trina, al igual que algunos de sus rivales insisten en que 182 mm deberían ser el estándar de la industria.
