Are photovoltaic cells the same as solar panels?
- Yes, they are the same thing.s
Anyone here have residential solar panels?
- I have some panels on my house and no they are not cheap. If you look around you can buy them for around $4.70 per watt for a 00 plus watt panel, this will make them $470 or more. But you will get a first quality panel. And no I do not know of any fed. government programs for home owners. These kind of programs usually only go to large companies. And it does not look like our government is going to help seeing how the let the large oil companies keep there tax programs but refused to help solar. This just happened today when the senate voted on the energy plane. Good luck go solars
Shouldn't 0bama increase our tax benefits for solar panels so we can buy more Chinese products?
- America should be making the panels and imposing large tariffs on any country trying to import theirs here.s
QUestion about portable Solar Panels.. Mine is 2v?
- portable storage tank would be lead acid batteries. Use only marine sealed type for safety, about $300 each. You will need a charge controller to control the charging of the batteries. If you don't get enough sunlight, then the only alternative (aside from using the roof) is to get more panels. .s
Sizing solar PV panels?
- 75 amps @ 240 volts equals 8 kW not 9.4 kW, so first you have to make up your mind how much you want. Then you have to decide what size of solar panel you want. If it helps, the 6 units on our roof, each approximately m square, are rated for 4 kW in bright sunshine.s
What specification of solar panel do I need?
- Ive been employing the comparable photograph voltaic panels for 5 years, have flow some instances so as that they final lots longer than the roofs weve had over us. i'm coaching my young ones a thank you to construct wind turbines, because of the fact we shop having potential failiures whilst the wind blows. and recently its have been given very windy. I can charge banks of battery's and shop my place of work working from dc-ac converters.s
What capacity solar panel do I need to charge batteries with a total capacity of 25,000 mAhours in 8 hours?
- Each battery pack has the equivalent of only 2450mAh capacity at 4 volts, so for 4 battery packs like that, a total capacity of 9800mAh. Assuming that the solar batteries have no charge left after being on all night, and that day charging time equals night discharging time, the theoretical wattage would be 9800mA times 6 volts = 59 watts. Of course, battery charging is not 00% efficient, so you need more wattage than that. Plus, solar panels are rated at peak output at midday, while at other times of day their output is less than rated. And, the charging in parallel isn't a good idea, because real batteries have different internal resistances, some batteries would become overcharged, while other packs wouldn't get the charge they need.s
Solar panels?? I need help!?
- I live near a community in Mexico where hey have no power. It is in the desert and is perfect for solar because they only have 3-4 in. rain a year. It is on the beach so many wealthy have homes there that are on solar systems. I have helped my friends set up and work on many of them. Solar systems WILL NOT normally support air conditioning unless you install a gas powered ammonia or lithium Bromide system. In these systems the refrigeration cycle heat is supplied by the gas instead of a compressor, so the only electrical power is a small circulation pump which will not drain batteries fast. These are a problem in some areas because not many people know how to maintain and repair this type of system. Some of my friends claim they can run a very small one room AC on their solar systems just to at least have a place to sleep that is cool. Others say it is questionable. Please understand these systems are not cheap. Most of them paid $20,000 - $35,000 and even more if you use the ammonia cycle AC. The systems usually have 0-2 panels, a 0-5 KW gas generator, and large bank of large batteries like ones you use in a golf cart or bigger. I also must apologize to all the environmentalists for the inconvenient truth.s
