Solar panel working process

In addition to being the ultimate source of all life on earth, the sun is an infinitely renewable, completely pollution-free source of electricity. Instead of burning fossil fuels dug up from the ground in a big power plant – a very 19th century, industrial age approach, when you think about it – solar panels convert sunlight directly into electricity, with no harmful emissions.

The basic unit of a solar panel is a solar cell, which usually consists of one or two layers of silicon-based semiconductor wafers. When struck by the photons in sunlight, the solar cell generates an electrical charge due to the "photovoltaic effect" – which is a pretty good name, since it produces voltage from photons. The flow of these electrons moves in a steady electrical current from one side of the cell to the other.

Dozens of these PV cells are packaged together into solar modules, which in turn are packaged into solar panels that are mounted on a rooftop and arranged to maximize their hours of exposure to direct sunlight. Because the electricity generated by all those solar cells is direct current (DC), it is then sent to an inverter that transforms the power into the same alternating current (AC) used by the appliances in your home and the local utility electricity distribution grid. Increasingly, these inverters are getting "smart," providing data monitoring for solar installation performance and other grid integration services.

 

 

Q: Can solar panels be used in areas with high levels of rainfall?
Yes, solar panels can be used in areas with high levels of rainfall. Rainfall does not necessarily affect the functioning of solar panels as they primarily rely on sunlight to generate electricity. However, it is important to ensure that the solar panels are properly installed and maintained to prevent any water damage or reduced efficiency caused by excessive rain.
Q: Can solar panels be used on commercial buildings?
Yes, solar panels can definitely be used on commercial buildings. In fact, many businesses and organizations are increasingly adopting solar energy as a way to reduce their carbon footprint, save on energy costs, and demonstrate their commitment to sustainability. Solar panels can be installed on rooftops, carports, or open land surrounding commercial buildings, providing a clean and renewable source of electricity.
Q: Can solar panels be used in areas with extreme temperatures?
Yes, solar panels can be used in areas with extreme temperatures. Solar panels are designed to withstand a wide range of temperatures, including both extreme heat and cold. However, it's important to note that extreme temperatures can affect the efficiency and performance of solar panels. High temperatures can cause a slight reduction in energy output, while extremely low temperatures can decrease the efficiency temporarily. Nonetheless, solar panels are still a viable and effective renewable energy solution in areas with extreme temperatures.
Q: Do solar panels require a battery?
No, solar panels do not require a battery to function. However, batteries can be used to store excess energy generated by solar panels for use during cloudy periods or at night when there is no sunlight.
Q: How do solar panels impact the roofing material's lifespan?
Solar panels can actually extend the lifespan of roofing materials. They act as a protective layer, shielding the roof from various weather elements like UV rays, hail, and rain, which can cause damage over time. Additionally, solar panels can help regulate the temperature of the roof, preventing excessive heat buildup that can accelerate the degradation of roofing materials.
Q: 3.8 volts is required to fully charge a battery. But at 3.8 volts, the battery can be overcharged without the use of a controller correct? What if I don't care if the battery is fully charged? In the case of our family boat, I just installed a new radio, so I'm a little worried about power consumption. So now for the real question; If I hook a 2 volt panel to the batteries, do I need to worry about overcharging them? Or will the batteries stop the charging process once they reach 2 volt?I built the panel myself, it's 8 volts at 3.5 amps open circuit. I have tabs at every 3 volt increment on the panel so that I can use less voltage than 8 if I want to power something directly, (ex:2 volt radio)So I'm using the 2 volt tab at 3.5 amps(approx) for a total of approx 48 watts
Batteries will not stop charging on their own. The will stop charging when the battery voltage equals the supply voltage. Solar panel open circuit voltage is typically around 20V. Batteries will just boil dry before reaching 20V. One rule of thumb, above 0W you need a controller for sure.
Q: Can solar panels be used in areas with high wind speeds?
Yes, solar panels can be used in areas with high wind speeds. However, it is important to consider the structural integrity of the mounting system to ensure that the panels can withstand strong winds. Additionally, proper installation and maintenance are crucial to ensure the longevity and efficiency of the solar panels in such conditions.
Q: Can solar panels be installed on the ground instead of a roof?
Yes, solar panels can be installed on the ground instead of a roof. Ground-mounted solar panels are a popular alternative when roofs are not suitable or available for installation. Ground-mounted systems offer flexibility in terms of placement, orientation, and size, making them an excellent option for maximizing solar energy production.
Q: Can solar panels be easily removed and relocated?
Yes, solar panels can be easily removed and relocated. They are typically designed to be modular and can be disassembled and reinstalled in a new location with relative ease. However, it is important to consult a professional to ensure proper disconnection, transportation, and reinstallation to maintain their efficiency and safety.
Q: DIY, buying solar panels, room is barely 200 sq. ft. have a 5000 btu air conditioner, how many watts do I need, thinking of buying 75 watt solar panels, have space on the roof.
It may cost you about $650, you can also learn building it yourself so you can save much money...
