Do they really save energy? Cut or almost eliminate your electricity bill, if so, how much?Do they have a reserve unit to save electricity that I don't use, to use when the sun is not out?Can it produce enough electricity to cool a house and keep lights and appliances runningLastly, how much are the panels are running for.
You need an expert to tell you what the best solar panels are, in any case there is a gigantic outlay initially, each solar panel when I bought mine was around $ 600. I only had the two for my caravan, along with two heavy duty deep cycle batteries, they are able to discharge very low without damage to them, I have a small inverter which gives me 000 watts pure sine wave 240 volt. With my small set up I can use a micro wave oven and bread making machine as well as running power tools radio and television. Lighting can be efficient on ordinary 2 volt dc.They are far better than wind power I have tried that as a back up but I found it a waste of time and money most of the time. If you are connected to the mains power any power you don't use can be sold to the power supplier. With the really serious set up you can do anything with your power that you can do with the power suppliers. I set this of mine up to get away from the petrol generaters, I have had my panels for about 5 years and they are putting out the same wattage that they were when I bought them. I have not gone in for it seriously but I was told by someone that their mother had set up a system for $4,OOO and she received a grant of the same amount from the government and she sold her surplus power to the local power supplier. Incidentally I live in Western Australia.
Instead of paying for electricity, for the past three years I've actually ended up with a cheque from the power company believe it or not! :) I got some extremely cheap solar panels from this guide I read, I'll try and find a link for you.. that's one less thing to worry about during the recession I suppose! Haha The guide I used was here: tiny /solar789 my mum was the one who said I should take a look at it, since she's been using the techniques for donkey's years.
It Can produce enough energy to run fans and yes keep the house cool. And if you also want to make one try it out. Good luck and save energy
In California, if a house is now connected to the grid, typically, they stay connected to the grid even after installing solar electric panels. In this way, no batteries are required to run at night or over cloudy periods. And the house gets credit for energy generated in excess of usage. This scheme also means that you can size your array to only generate a portion of your electrical usage, which is also the usual decision. Since you mention cooling, an air conditioner is a big power drain. We have no A/C, so a modest 3 kW array is enough to supply all our electrical needs. If we had central air conditioning, that number might be doubled or tripled. Your best bet is to contact a local solar installer to do an analysis and quote on your house. How much it costs, and whether you actually will save money in the long run, depends on where you live, and how much electricity you use. Our system cost $2,000 after all rebates and credits.
