I know that there is a life expectancy for solar panels, and I suppose, the technology involved. Any information?
This Site Might Help You. RE: how long do roof solar panels last? I know that there is a life expectancy for solar panels, and I suppose, the technology involved. Any information?
So lets say that Everyday I use ,280 kWh. How many 250 watt solar panels would I buy so that I don't need to buy electricity anymore. Sorry if this sounds stupid, I am doing research on why american homes should become more cost efficient.
Everyday I use ,280 kWh 280 kW-hour / 24 hours = 470 kW WOW, that is a very high power level, most homes use an average of .2 kW. My guess is that you mean you use 280 kW-hour in a year, which comes to an average power of .3 kW, typical. Assuming you get, worse case, 6 hours of sun per day, for the first case, 470 kW, each solar panel generates the equivalent of 250 x6/24 = 60 watts, so you would need 470k/60 = 8000 panels For the second case, .3 kw or 300 watts, divided by 60 that is about 20 panels. Depending on where you live, you could need as much as twice that number. Plus you need charge controller, lots of expensive batteries, and an inverter. The big problem is periods of no sun. If you demand continuous power, and you have a period of, say, 24 hours with no sun because of storms, etc, then the number of batteries increases to the hundreds.
Does a solar panel work under a full moon a tiny bit, or not at all? Likewise, if you used mirrors or lenses the concentrate sunlight, is there a maximum to how much a solar panel can handle?
solar panels should be used where the sunlight is abundant,you can use mirrors or lenses the concentrate sunlight,solar panels will absorb more light.
Yes, there may be restrictions on installing solar panels in certain areas. These restrictions can vary depending on local regulations, homeowner association rules, and building codes. Some areas may have permit requirements, aesthetic guidelines, or zoning restrictions that limit the placement, size, or visibility of solar panels. It is important to research and comply with these regulations before installing solar panels in any specific location.
I live in Sacramento, CA, and I need some solar panels for a project fo school. They don't have to be very big......just something that I can use as an example.Thanks!
I did the same thing recently, if you'd really like some free ones then you need to look for those little solar powered lamps that people put in their yards, theyre about 0 inches tall and people sometimes line the paths through their yard with them. Maybe you can find a neighbor who doesn't want theirs anymore, or you could check local dumps for them. They each have a solar panel in the top, and they can be linked together to make more power. Alternatively, you can look on OKorder for a pack of broken solar cells, which still work fine but don't put out quite as much power as they did when they were new. However, they are very cheap. Hope this helps.
Yes, solar panels can be installed on a library or educational institution. In fact, many libraries and educational institutions have already embraced solar energy and installed solar panels on their rooftops or surrounding areas. This helps them reduce their carbon footprint, save on electricity bills, and serve as a sustainable example for the community.
Yes, solar panels are a good investment for several reasons. Firstly, they can significantly reduce or eliminate your electricity bills, resulting in long-term cost savings. Additionally, solar panels are environmentally friendly as they harness clean and renewable energy, reducing your carbon footprint. Furthermore, government incentives and tax credits are often available, making solar panel installation more affordable. Lastly, solar panels can increase the value of your property, providing a return on investment if you decide to sell in the future.
I would love to put in solar panels on my roof, but how hard would it be, and how expensive? Would I be able to do the work myself, or would I have to hire a pro?Also I live in Oregon, so much of the time it is overcast, so would it really be worth it?
Not worth it unless you can get a fat subsidy. But Congress is working on a bill to provide a significant subsidy, and Oregon may have one as well. A solar plant costs about $0 per watt of installed capacity, and can produce a maximum of two kWh per watt per year -- which is worth about two bits. Without a subsidy, you are better off leaving your money in a savings account.
