Well if you had "3 years study" which I sincerely doubt you would now how utterly ridiculous, impractical, expensive and eco-unfriendly Solar is.
First find what you use in power in one day ( in kwh ). You can check your utillity usage through the Company that you buy electricity from.
Go to one of many online calculators and calculate out the SIZE of the array you'll need, and the COST to install.
I did this a couple of years ago and with Subsidies, ( yes, the Government has to Subsidize it it SUCKS so bad ) it was 24,000 dollars to lower my Bill by HALF.
Typical ROI on Solar is 20 - 30 years, typical warranty on the very expensive components is 15. Look up Solar Halo, because I think your'e wearing one.
Wind ? what a joke. Inneficient, expensive, high maintenance, bird eating including bald eagles scar on our landscape.
To become more "efficient" we wen't back in time apparently.
Your 3 "years of study" I hope disn't cost you anything because if I were you I would want my money back.
WOW! Fight for your limitations and they shall be yours!
Not sure where to start... but your complaint about the warrantee is hilarious. Name anything in your house that has a warrantee longer than a year. Most products have a 90 day warrantee... does that stop you from buying it? Do you throw it out after the warrantee is up? Does it stop working after 90 days? You don't mind if this is dismissed, do you? Also, the usable life of most modern cells is in excess of 30 years.
Next, your concern for the birds is also hilarious. Traditional energy sources of far more massive impacts on the environment and ecosystems than windgen ever will. But I appreciate you trying to get in touch with your liberal side..LOL As for high maintenance... preventative once every two years and rarely needing parts replacement is NOT high maintenance, it's very, very low.
Onward.. Anyone that wants to save on their power bill by installing renewable sources and doesn't undertake what I call an Apollo 13 program is pissing away their money. This means, you have to change your conspicuous consumption habits. If you have "X" amount of gen capacity, you should do everything you can to lower your consumption to meet that. That means no electric water heaters, changing your lighting, using laptops instead of desktop PCs, using ammonia based refrigeration and ac, solar heating and so on. There are many ways to reduce your consumption without changing your lifestyle. Though ditching the TV would go a long way.
Installation cost... Anyone that pays to install solar is either hopelessly inept or lazy. Anyone that can use a cordless drill, a socket wrench and a screwdriver can install solar. Cost eliminated. Final electrical connection will have to be done by an electrician, most people know one.
Since you're keen on online calculators, you should have consulted local, state, federal and utility incentives and rebates. Most folks can reduce their cost by 20-30%.
Lastly, advancements in efficiency are happening on a nearly quarterly basis. In fact, I'm willing to bet that it's improved since you last looked at systems.
Everything I've listed, and much much more (this is only a brief sketch out) has been put in into practice in many locations.
