    Free Energy Solar Powered Radio

    About: Hello friends i show how to make stuff with no skills easy to replicate step by step from powerbanks,generator,invertors and so on thanks About NoskillsrequiredN »

    Free energy solar power radio diy is an easy project to convert an old battery operated the radio in a solar powered radio that you can call free energy because it uses no batteries and it operates when is sun and with the help of solar panel converting the solar power in dc electric power.This video was filmed in eastern Europe Romania and i will like to thank youtuber victor’s channel and i did put her video in this solar energy radio i hope she will be alright with it thanks. Going back to our free energy project you will need 6v 1w solar panel and a 9v or less radio and you are set in any location you can hear local am/FM radio battery free. Solar panels absorb the sunlight as source of energy to generate electricity or heat.

    A photovoltaic (PV) module is a packaged, connected assembly of typically 6×10 photovoltaic solar cells. Photovoltaic modules constitute the photovoltaic array of a photovoltaic system that generates and supplies solar electricity in commercial and residential applications.

    Step 1: How to Convert Your Radio to Solar

    Hello friends i will present today how to convert any radio dc powered (battery operated) in a free energy solar powered radio that can be used all over this planet the only condition is to be sunny and maybe in the future we will modify this with a power bank to store the power and run the radio and when is cloudy BAMMM run of the battery power bank or 18650.

    For this project almost any radio dc powered will work an USB one is best but in the video from the end of this tutorial i used a 9v dc radio powered with 7.2v at 0.10A and you can go as low as 5v you have to adjust your panel according to your panel we did manage to find this 6v 1w panel but the ratings are overrated but is gonna do the job.The first picture is the plus and the minus. of the radio, this is the only tricky part to find the terminals of the radio because any radio has the pins /- indifferent position but tested with a 9v battery the easy way normally (but not a rule) is the diagonal terminals.

    Step 3: The Solar Panel

    Solar panels absorb the sunlight as source of energy to generate electricity or heat.A photovoltaic (PV) module is a packaged, connected assembly of typically 6×10 photovoltaic solar cells. Photovoltaic modules constitute the photovoltaic array of a photovoltaic system that generates and supplies solar electricity in commercial and residential applications. Each module is rated by its DC output power under standard test conditions (STC), and typically ranges from 100 to 365 Watts (W). The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 W module will have twice the area of a 16% efficient 230 W module.

    A solar cell, or photovoltaic cell (previously termed solar battery), is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon.It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Solar cells are the building blocks of photovoltaic modules, otherwise known as solar panels.

    Solar cells are described as being photovoltaic, irrespective of whether the source is sunlight or an artificial light.

    With the help of a multimeter you will find the terminals of the solar panel and connected according to polarity solar to radio and.sola and if you want to be more mobile connect some crocodile clips to make the connection.

    Thanks for your time and check the video for more details and proof all the best

    How do solar panels work?

    What makes these alternative energy sources function?

    Solar panels crown rooftops and roadside signs, and help keep spacecraft powered. But how do solar panels work?

    Simply put, a solar panel works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity, according to the University of Minnesota Duluth. Solar panels actually comprise many, smaller units called photovoltaic cells — this means they convert sunlight into electricity. Many cells linked together make up a solar panel.

    Each photovoltaic cell is basically a sandwich made up of two slices of semi-conducting material. According to the Proceedings National Graduate Conference 2012, photovoltaic cells are usually made of silicon — the same stuff used in microelectronics.

    To work, photovoltaic cells need to establish an electric field. Much like a magnetic field, which occurs due to opposite poles, an electric field occurs when opposite charges are separated. To get this field, manufacturers dope silicon with other materials, giving each slice of the sandwich a positive or negative electrical charge.

    Specifically, they seed phosphorous into the top layer of silicon, according to the American Chemical Society, which adds extra electrons, with a negative charge, to that layer. Meanwhile, the bottom layer gets a dose of boron, which results in fewer electrons, or a positive charge. This all adds up to an electric field at the junction between the silicon layers. Then, when a photon of sunlight knocks an electron free, the electric field will push that electron out of the silicon junction.

    A couple of other components of the cell turn these electrons into usable power. Metal conductive plates on the sides of the cell collect the electrons and transfer them to wires, according to the Office of Energy Efficiency and Renewable Energy (EERE). At that point, the electrons can flow like any other source of electricity.

    Researchers have produced ultrathin, flexible solar cells that are only 1.3 microns thick — about 1/100th the width of a human hair — and are 20 times lighter than a sheet of office paper. In fact, the cells are so light that they can sit on top of a soap bubble, and yet they produce energy with about as much efficiency as glass-based solar cells, scientists reported in a study published in 2016 in the journal Organic Electronics. Lighter, more flexible solar cells such as these could be integrated into architecture, aerospace technology, or even wearable electronics.

    There are other types of solar power technology — including solar thermal and concentrated solar power (CSP) — that operate in a different fashion than photovoltaic solar panels, but all harness the power of sunlight to either create electricity or to heat water or air.

    The electric field

    To generate electricity, we first need to establish an electric field. It’s like a magnetic field: just as the opposite poles of two magnets attract each other, so do the positive and negative charges in an electric field. This opposites attract electric field is created in the cell when its two different silicon layers are first brought together in the factory. The extra electrons in the phosphorus-doped top layer naturally move into the boron-doped bottom layer—a process that occurs in a fraction of a second and only very close to the junction (the point at which the two layers meet). Once the bottom layer has gained extra electrons, it becomes negatively charged at the junction; at the same time, the top layer has gained a positive charge there. Now the cell is ready for the sun.

    As sunlight hits the cell, its photons begin knocking loose electrons in both silicon layers. These newly freed electrons dart around each layer but are useless for generating electricity unless and until they reach the electric field at the junction. (This relative inefficiency compared to that of fossil fuels is part of the reason why solar cells still only account for less than 0.1 percent of the energy used in the U.S.) The electric field pushes electrons that do reach the junction towards the top silicon layer. This force essentially slingshots the electrons out of the cell to the metal conductor strips, generating electricity.

    Powering the house

    Electrons flow as electricity via the metal conductor strips into a wire and thence to an inverter inside the house. This device converts the direct current coming from the PV cell into the alternating current our appliances can use. As noted earlier, electrons also flow out of the house and back to the solar panel, creating the closed loop necessary to maintain the flow of electricity. The cell keeps generating electricity, even on cloudy days, until the sun goes down at night. To see solar power in action, check out This Solar House.

    Advantages of Solar Energy

    The more we can capture the benefits of solar energy, the less we will rely on fossil fuels. Adding a solar energy system to your home allows you to tap into these solar energy advantages:

    Solar energy is a renewable energy source and reduces carbon emissions

    Solar energy is a renewable energy source, meaning you don’t ever use it up. Solar energy is clean. It creates no carbon emissions or other heat-trapping “greenhouse” gases. It avoids the environmental damage associated with mining or drilling for fossil fuels. Furthermore, solar energy also uses little to no water, unlike power plants that generate electricity using steam turbines.

    ​​Solar energy can reduce your home’s electricity bill

    A solar energy system for your home can reduce your reliance on the grid and help you save on your electricity bill. Some owners of residential solar energy systems may even have excess power that they can sell to the utility. Instead of paying a utility for electricity, homeowners get paid by the utility. You may not have to buy an entire solar energy system to cut your home’s electricity bill. Simply choose solar lights, lights that are powered by the sun instead of your home’s electrical system, to help save money.

    Solar power can get you money back through Solar Renewable Energy Credits (SRECs)

    Some states offer solar renewable energy certificates (SREC). Each one represents a megawatt-hour of electricity generated through solar energy. Electricity suppliers buy these certificates to satisfy their state’s Renewable Portfolio Standard, a requirement that a certain amount of their renewable energy come from solar. You can sell SRECs for your system’s output, which is another way to earn money from your investment.

    Homes with solar panels installed may improve home value

    Home buyers will likely pay more for a house with solar panels installed. Considering solar energy pros and cons, the savings on electricity bills and the money earned selling power back to the utility, all count in the plus column. Residential solar energy systems are highly valued and can increase a home’s resale value. The property value of a home with solar panels can be worth up to 15,000 more than its neighbors.

    Solar systems are fairly easy to install and require very little maintenance. Both are handled by your solar provider, if you opt for a solar lease or power purchase agreement (PPA). Consider this as you ask yourself is solar energy worth it.

    Solar panels have low maintenance costs

    Solar panels are easy to maintain, as they have no moving parts that wear out over time. Just keep them clean and in good physical condition to keep them working properly. Between their low maintenance costs and average lifespan of 25 years, it can be easy to get your money’s worth when investing in solar panels.

    Solar energy can generate electricity in any climate

    Solar energy systems can generate electricity in any climate. One of the disadvantages of solar energy is that it’s subject to temporary weather disruption. Cloudy days reduce the amount of electricity you produce. Cold, however, doesn’t affect productivity. Snowfall can actually help your solar system, as the snow cleans the panels as it melts and sun reflected off the snow increases the amount of light hitting your panels. The result is more electricity production.

    Disadvantages of Solar Energy

    The disadvantages of solar energy are becoming fewer as the industry advances and grows, creating economies of scale. Technological advances are helping solar go mainstream. Here are how the disadvantages of solar energy and the pros and cons stack up.

    The high initial costs of installing panels

    The most commonly cited solar energy disadvantage, cost, is declining as the industry expands. The initial cost to buy and install the equipment is not cheap. Still, if cost is an issue, leasing options may reduce the amount of your initial outlay. If you do choose to buy, you will need to live in your home for a number of years before the system pays for itself. It’s a long-term investment better suited to property owners than renters.

    Solar energy storage is expensive

    Of the disadvantages of solar energy, the temporary decline in energy production during bad weather has been a major issue. Days with low solar energy, however, are having less of an effect due to advances in battery technology. Old technology for storing solar energy, like lead acid batteries are being replaced by alternatives. Lithium ion batteries offer greater power at a lower cost. Nickel-based batteries have an extremely long life. New technologies, like flow batteries, promise scale and durable power storage.

    Solar doesn’t work for every roof type

    Not every room will work well with solar panels. Orientation matters. If your roof doesn’t face the sun, you won’t be able to capture enough solar energy. Roofs that angle into the sun tend to work better than flat roofs.

    free, energy, solar, cell, generating

    Roofing materials like asphalt shingles, metal and tiles make installing solar panels easier. If your room is made with other materials, installation may be more expensive. Part of what makes energy-efficient roofs is their ability to support solar panels.

    Solar panels are dependent on sunlight

    It’s obvious that solar panels need sunlight to generate electricity. They won’t produce electricity at night when you need it for light and they can be inefficient during storms and gloomy days. Your solar energy system needs batteries if you plan to fully depend on solar energy to power your home.

    free, energy, solar, cell, generating

    Batteries are one of the more expensive components of your system. Unlike solar panels, they do wear out and need careful maintenance to lengthen their lives. Comparing wind power vs. solar power, wind will keep generating electricity at night and during storms, as long as there is enough wind. Many people use both in residential systems.

    Constellation Energy and Solar Energy

    When weighing the pros and cons of solar energy for your home, there are additional options worth considering. Community solar projects are a great way to get the advantages of solar energy without buying and maintaining a system yourself.

    If your home and roof won’t support solar panels or if you don’t have enough money to invest in one, community solar might be your answer. With this option, you agree to participating in a program that allows you receive credits for every kWh generated by the solar facility. You get a credit on your electricity bill proportional to your percentage of ownership in the project’s energy.
