- Q:i see these things all over the internet on how to make 'home made solar panels' but all of them require you to buy the solar cells and nothing tells you how to make your own. So how can you make your own solar cells?
- I don't have an idea but would surely refer you to a website where you would surely find information on solar cells and many more alternative energy questions.
- Q:I've heard that solar panels have back-up batteries for when it is cloudy or rainy that day.. is this true?
- depending whether the solar array is back to grid or stand alone. Back to grid refers to the array being connect through the inverter to the main electricity supply grid. So when you are producing electricity from the solar array it feeds back into the main grid. Now if you are using more electricity than your array is producing then none will feed into the grid. The stand alone systems require batteries, which are charged from the electricity produced by the solar array. Solar arrays produce electricity on cloudy and rainy days but at a greatly reduced rate ; therefore little to no usable electricity is produced. Stand alone systems require batteries to store the electricity for use at night time and other times when the array is not producing . The back to grid systems require little to no maintenance as the electricity produced is fed back into the electricity network and stored there. Your meter is replaced with a dual meter . It reads your usage and your production. If in Australia you will get paid for the electricity you feed back into the grid. hope this helps.
- Q:Can solar panels be installed on outdoor event venues?
- Yes, solar panels can be installed on outdoor event venues. In fact, outdoor event venues are often ideal locations for solar panel installations as they provide ample sunlight exposure. Installing solar panels can help event venues generate clean and sustainable energy, reducing their reliance on traditional power sources and lowering their carbon footprint.
- Q:Can solar panels be used in areas with high levels of air pollution?
- Yes, solar panels can still be used in areas with high levels of air pollution. While air pollution can reduce the efficiency of solar panels, they can still generate electricity even in polluted environments. However, regular cleaning and maintenance may be required to ensure optimal performance in such areas.
- Q:I want to install solar panels in my roof and most installers don't recommend any particular brand. Do you have experience with any particular brand that has worked for you or anybody you know? Does the brand of the panel make a difference?
- Mitsubishi panels have served us well for 3 years so far, no problems. Kyocera had a well-known problem many years ago, but they lived up to the warranty and replaced defective panels. Their current products are considred good. I like the value delivered by Suntech panels. Might be a best buy - shop around. I have not heard about any of the major brands having trouble, lately. If you're intending to connect to the grid, be cautious about used or blemished panels. While they might work fine, they usually are ineligible for rebates.
- Q:How much per sq inch do they cost? Will i have to worry about them blowing off during hurricane season? If the sun isnt out for a week will my power go out? Will I have to check them every week and check which ones arent working and replace them? Is there anyway for them to be damaged by acid rain or any type of erosion like hail? When do I have to replace them? How do I dispose of old ones (like recycling)? What is smarter and more economical having few big panels or many small ones? I know I have alot of questions but I want a good detailed answer.
- They don't sell them by the square inch. It costs about $0 per watt of generating capacity. Unless you are connected to the grid you will need a battery bank to storage power for rainy days. As for the effects of weather ... you can probably make a cover out of plywood... but if your house blows away the solar panel goes with it. Before you buy one make sure your insurance covers it.
- Q:Can solar panels be installed on warehouses?
- Yes, solar panels can be installed on warehouses. In fact, warehouses are ideal locations for solar panel installations due to their large roof spaces and minimal shade obstruction, allowing for maximum exposure to sunlight and optimal energy generation.
- Q:Polycrystalline solar panels are good or single crystal solar energy is good
- . Since monocrystalline silicon is typically coated with tempered glass and waterproof resin, it is rugged and durable for up to 15 years and up to 25 years.
- Q:Can solar panels be installed on a farm or agricultural facility?
- Yes, solar panels can definitely be installed on a farm or agricultural facility. In fact, many farmers and agricultural businesses are increasingly turning to solar energy to reduce their reliance on traditional power sources and lower their operating costs. Solar panels can be installed on rooftops, barns, or open fields, providing a sustainable and clean source of electricity that can power farm operations, irrigation systems, or even be sold back to the grid. Additionally, solar installations on farms can also qualify for various incentives and grants, making it an economically viable and environmentally friendly choice for farmers.
- Q:I'm doing a project for school and I'm a little confused about energy and solar panels. I'm looking to propose installation of solar panels to power the computer lab at my school. From what I've read a computer and monitor use roughly 350 watts per hour. I was looking at solar panels and it says they produce various wattage. For example, I was looking at one rated at 200 watts. Does that mean 200 watts in a day? Or per hour? Please help.
- The rating of a solar panel is a maximum continuous rating. A 200 Watt panel will give a maximum of 200 watts under ideal conditions. A computer and monitor use about 400 Watts. not per hour - watts is Volts * Amps and a measure of Power. In hour a computer and monitor uses 400 Watt hours (Wh). Wh is a measure of Energy. To power a lab of 0 computers you will need 0* 400 = 4000 Watts. To run this from solar panels through the day only you would need a 4000 Watt panel. Except - its cloudy, the sun is in the wrong place - many factors reduce the output. To be reasonably safe you would need about a 2000 Watt panel. Then you would need batteries to store power through dull periods AND a voltage converter to change from low voltage DC from the solar panels to the mains voltage for your computers.
