I want to buy Solar power system for my home, What are the recommendation? If somebody has used it?

I've looked into it. The systems are very expensive, in that it would take many years to realize your utility savings. Unless the government gives incentives, and tax cuts to the manufacturing industry & consumer, these systems will remain expensive, and out of reach to the common homeowner

Really? But I saw some companies persuade us to install solar energy heater in the basement(generate electricity parallel with gas supply). They say, we just need two years to get the money back. (totally cost 4000, and government pays 2500, and we pay 1500. Is it true?

Both are effective operationally. However, I strongly suggest a break even analysis. I believe that you will discover it is a very uneconomical.

It can be cost effective, depending on where you live.

An abundance of clear, sunny days, or strong, steady winds helps your case, as do high local electricity prices.

When solar pays back, it's generally over a period of 10, maybe 20 years. And maybe never.

We have solar electric on our house. It supplies essentially 100% of our electric power. It's only break-even over the long term, not a savings over the electric company. I'm quite happy with the system. I can send you a link to more information, if you're really that interested. My email is in my profile.

The best way for you to price out a solar system is to ask a solar installer in your area to give you a free quote. You can always say no. If it looks good, then get other quotes to compare before you buy.

You might want to consider checking out one of the best alternitive energy sites on the internet. It explains the whole process.

solar power, wind power

Well it all depends on where you live, if you're out in the country, wind power may make more sense for you, if you're in the city solar is the way to go. With a solar electric system there are no moving parts so it lasts a long time, it pays for itself depending on where you live i have heard of getting money back in three years. If you finance it very often the payments are less than your electric bill. The only maintenance is hosing it down once in a while. I also recommend looking into geothermal, especially if you have a decent sized backyard, its actually the cheapest option, and if you have plenty of space out back its even cheaper. Depending on where you live the payback differs, in the US, we happily now all receive a 30% tax credit, that helps cut the price. there are also other programs pretty much in every state by now. Out here in California, its state mandated for the utility companies to offer a rebate.
