Q:I read on CNN's website last year some company was creating a very cheap type of solar panel, that needs minimal maintenance and and has minimal glare from the sun. And the creator of the project said he one day wanted to cover every rooftop in the US with these solar panels. Seems like a good idea to me but I havent heared anything of it for a long time and I don't know what they are called... any help?
The cheapest will be solar paint where you lay down some wires and paint the panel on. Solar roof tiles are also coming along but each tile has to be wired in. Currently the target is $ a watt. The efficiencies of these panels are very low but if the cost is low enough then the efficiencies won't matter. Keep in mind that even fossil fuel is solar power, just solar power captured by photosynthesis millions of years ago, and photosynthesis has a maximum theoretical efficiency of 6.6% with most plants achieving less than % efficiency so even an inefficient solar paint already outstrips our current energy sources in terms of efficiencies. The real problem is the business model. With solar energy you can sell the panels upfront but then what do you do for an income whereas with fossil fuels, you sell every kwh and bill each month.
Q:
Yes, solar panels can be used to power electric fences. By harnessing the sun's energy, solar panels can generate electricity that can be stored in batteries and used to power electric fence systems. This renewable energy source offers a sustainable and cost-effective solution for powering electric fences in remote areas or locations without access to traditional power sources.
Q:
Solar panels can potentially obstruct the satellite dish's line of sight to the satellite, leading to signal interference and reduced reception quality.
Q:Could you throw some long scientific words in with your answer so I can impress my teacher, I'm looking to expand my scientific vocab. Thanks
Solar panels are a generic term for any type of solar collecting panel. There are two major types: Photovoltaic uses substances that turn the incoming radiation directly into electricity. Usually you have to have direct sunlight (no clouds) for this to work well. Solar thermal is also used in a lot of areas. Here the radiation is used to heat a circulating fluid (often water directly), and then that is either used directly, or it's used for heat exchange with a heat pump or a boiler system. Solar thermal can collect significant heat even on a cloudy day. So a solar panel could be made of photovoltaic panels, but it doesn't have to be.
Q:i am very much interested in making a solar panel, my problem is where i can acquire the main components in order to build it, i am staying here in abu dhabi UAE i'm always searching on the internet for shops that can provide me a DIY kit but i did not find one, i need somebody who knows where i can get these things, please let me know.

Q:I been considering to get a solar panel system but I don't know if I'm going cut my electric bill every month , It's a lot of money to spend and I'm not really sure

Q:
Yes, solar panels can be used in areas with high humidity or saltwater exposure. However, it is important to use solar panels specifically designed to withstand these environmental conditions. These panels are typically made with corrosion-resistant materials and protective coatings to ensure their longevity and performance in such areas. Regular maintenance and cleaning may also be required to prevent any build-up or damage caused by saltwater or high humidity.
Q:quot;Does it take more energy to produce a solar panel than what the same solar panel can generate in its useful lifetime?quot;
I haven't any theory what you're doing or what you think of you're attaining. A 235 watt panel isn't lots potential. you may easily save it with a undeniable previous lead acid battery.
Q:I need to build a battery array to use with my solar panels I just bought. I want to be able to store enough energy to be draw from it at night, possibly around the clock. Is there a down side to using the deep cycle battery I bought from autozone and 6 or 7 more just like it, or do I need to get some other battery?
There are batteries particularly made for solar, such as the Trojan T05-RE . I think the RE stands for renewable energy. A deep cycle battery should work all right, although not quite as well. What you want to do is try out your setup first, with just one battery, and the panels provided. If this is one of those 45 watt kits, you may be surprised at how little energy you actually get from the panels. Increasing the number of batteries won't help, either - that's like getting a larger water tank, when you only have a trickle to fill it. If your goal is really to save money, the most cost-effective solar is the grid-tied type, with no batteries at all. That's what we have, and I've never regretted it.
Q:
The cost to replace a solar panel can vary depending on factors such as the type, size, and quality of the panel, as well as any additional installation costs. On average, the cost can range from a few hundred to several thousand dollars per panel. It is recommended to consult with a professional solar installer or company for an accurate estimate based on your specific needs.
