Q:when we say a solar panel has 20% efficiency, do we mean that it converts 20% of sunlight reaching it into electricity or that it converts 20% of visible light(which is only 7% of sunlight) into electricity?

Sunlight power panels had been the go-to choice for many years. They are among the many oldest, most efficient and most liable methods to produce electrical energy from the solar. Every module is made out of a single silicon crystal, and is more efficient, although more pricey, than the more moderen and less expensive polycrystalline and thin-film PV panel technologies. You can normally appreciate them through their color which is more often than not black or iridescent blue. The silicon crystals have lengthy existence and they may be able to withstand wear and tear with out degrading its workability. Additionally solar is a main source renewable vigour as far as the sunlight method is worried. Sunlight has little influence within the residing creature. So sun panel should be in practice

Q:I am looking to buy a solar panel.What does it mean when in the title it says 200 watts, or 50 watts?

Q:Can solar panels be used to power an emergency response center?

Yes, solar panels can be used to power an emergency response center. Solar panels can generate electricity from sunlight, which can then be stored in batteries or directly used to power the center's equipment and infrastructure. This renewable energy source can provide a reliable and sustainable power supply, making an emergency response center less dependent on traditional energy sources during critical situations.

Q:about solar panel

The answer depends upon the type of solar energy captured . Photovoltaic Solar Panels convert the energy into electricity. This electricity is ran throughout the building via wires. Thermal Solar Panels typically capture the energy in the form of heat. The hot water is circulated through the building in water pipes.

Q:I thinking of buying a few solar panels, can anyone who had bought solar panels or sells them give me a price for them. I dot wanna over spend on them...

Solar okorder or another site to compare prices.

Q:How do solar panels affect the roof warranty?

Solar panels generally do not void a roof warranty, but they may have some impact on it. The installation process of solar panels involves drilling holes in the roof, which can potentially cause leaks if not done properly. Therefore, it is important to hire a reputable installer who is experienced in working with solar panels and understands the intricacies of a roof. Some roofing manufacturers may require specific mounting systems to be used, and failure to comply with these requirements may void the warranty. It is advisable to consult with both the solar installer and the roofing manufacturer to understand any potential impact on the roof warranty before installing solar panels.

Q:Do they really save energy? Cut or almost eliminate your electricity bill, if so, how much?Do they have a reserve unit to save electricity that I don't use, to use when the sun is not out?Can it produce enough electricity to cool a house and keep lights and appliances runningLastly, how much are the panels are running for.

It Can produce enough energy to run fans and yes keep the house cool. And if you also want to make one try it out. Good luck and save energy

Q:I'm trying to charge rechargeable AA batteries with a solar panel. What guage wire should I use to connect the panel to the batteries? Should I use a diode to keep the batteries from overpowering the circuit? If so, what size? My panel is 4.8V 50mA.

You not only need a diode, but a circuit that opens the circuit if the voltage falls below a certain level. The diode is not the problem, but the batteries powering the solar panel when the voltage falls to low.

Q:Can solar panels be installed on a gas station or fueling facility?

Yes, solar panels can be installed on a gas station or fueling facility. In fact, many gas stations and fueling facilities have started installing solar panels as a means to reduce their carbon footprint and decrease their reliance on traditional energy sources. Solar panels can provide renewable energy to power the facility's operations, including lighting, pumps, and other electrical systems. Additionally, solar installations can help gas stations and fueling facilities save on electricity costs in the long run.

Q:Does the new horizons has a solar panel for it power resources instead using nuclear generator?

It uses the nuclear decay of plutonium in a 'Radioisotope Thermoelectric Generator, or RTG. The heat of plutonium decay is captured and converted to electricity. Pioneers 0 and , Curiosity on Mars, and other deep-space probes use this, as the sun's light is too dim to use solar panels.
