- Q: Can solar panels be installed in areas with frequent power outages?
- Yes, solar panels can be installed in areas with frequent power outages. In fact, solar panels can be a great solution for such areas as they generate electricity from sunlight, reducing dependency on the grid. With the addition of energy storage systems, solar panels can provide uninterrupted power supply during outages, making them a reliable and sustainable option.
- Q: Can solar panels be installed on parking lots or garages?
- Yes, solar panels can definitely be installed on parking lots or garages. In fact, these areas are often ideal for solar panel installations due to their large, open spaces and exposure to sunlight. Installing solar panels on parking lots or garages not only helps generate clean energy, but also provides shade and protection for vehicles, making it a practical and sustainable solution.
- Q: What is the impact of dust and dirt on solar panels' efficiency?
- Dust and dirt on solar panels can significantly reduce their efficiency. When these particles accumulate on the surface of the panels, they block sunlight from reaching the photovoltaic cells, resulting in decreased energy production. Regular cleaning and maintenance of solar panels are crucial to ensure optimal performance and maximize their power output.
- Q: Can solar panels be recycled?
- Yes, solar panels can be recycled. The process involves separating the different components, such as glass, metals, and silicon, which can then be reused in the production of new panels or other products. Recycling solar panels helps reduce waste and promotes the sustainable use of renewable energy technology.
- Q: Can u guys help on how solar panels work and how it generates electricity?(or u can give me a good website that has solar panel info on it)~Thanks in advance!~
- Solar okorder under products that are sorted by watts per area. Also go to wikipedia to get more detailed information on solar cells.
- Q: Can solar panels be used for large-scale power generation?
- Yes, solar panels can definitely be used for large-scale power generation. With advancements in technology and decreasing costs, solar power has become a viable option for utility-scale projects. Large solar farms comprising thousands of panels are being built around the world to generate electricity on a massive scale. These solar installations have the potential to provide clean and sustainable energy for cities, industries, and even entire regions.
- Q: Im curious because I read about a boy who invented a 3d solar panel, using a pyramid he designed a solar panel that collects light more efficiently. Now I have a question. Why cant I design a solar panel that takes adventage of convex and concave mirror's and use a surface that collects light and then focus's the suns energy into a beam and take the beam into a chamber where the solar panels are sitting and surround them with mirrors as well, so any light not obsorbed by one particular spot is reflected to another area for reabsorbtion. I know solar panels dont absorb light but perhaps that will allow more light to create the effects it needs.
- I don't know anything about the 3D thing. You cannot get more energy out, than goes in. Energy will only hit the mirrors. With some loss of efficiency they would reflect a focused beam into the chamber, where with some more losses would reflect it to the solar panels. It would be more efficient just to expose all the panels to sunlight.
- Q: Hi, I bought 50 6X6 inch solar cells, I also bought a 40 amp diode, I still need to buy a battery, and inverter and a voltage controller, could you tell answer me the following questions:) I would like t build a small panel at first, (may be 0 X 0 inch), with that I would like (or at least to try) to power my laptop for the hole day, so I wont receive a very high amperage, yet, all the inverters I saw at e-bay are rated over 400 amp, if I buy a 400 amp inverter, can I use it with such a small amperage?2) what about buying a small car inverter, will it work?3) suggestion about the battery and the voltage controller will be kindly appreciated.Thanks
- I have an inverter that I use in my vehicle. It is rated for 400 amps this is it's maximum capacity. I can use it for less. It converts 2V DC to 20V AC. So Thais is all I need and may be your cheapest option. If your panels are producing a lot of amperage you may need a regulator to stop charging when your battery is fully charged.
- Q: What is the working principle of solar panels?
- the material is easy to industrial production and material performance and stability.
- Q: What is the most affordable, yet highest watt solar panels available?
- Those two requests are somewhat at odds with each other. Trina and Suntech make panels that are generally good value. You can search the web and find your best price. If this is for something that does not need to last long, you could get amorphous panels and save some money. But they will degrade quickly in a few months, then slowly over a few years.
