Cost vary on the size and difficulty of the project. The price of the panels are dropping and technology is getting better. A rough rule of thumb estimate would be $3 per watt for all the hardware and then double that to cover labor and overhead (insurance, permits, gas for the truck etc)
Solar thermal has a faster payback than PV.
The panels themselves go up fairly quickly. Installing roof mount attachments can take some time. This is also one of the points of liability. If done improperly the roof may leak and cause more damage than the profits on that job could pay for.
There are a number of kits and pre-bundled packages available. You might try installing one of those on a friendly first. Make it a weekend project for yourself or on a friend or relatives house.
The cost of a solar power system depends on various factors including the number of panels, the size of the inverted, the number of storey on your home & your location.
Cba to read all that, but all I know is for 3 sola pannles it cost abot 5000 xxx
some 40,000-60,000 Rupees
So my buddy and I have an idea to start a small Solar Installation business. Small as in I am only willing to do one weekend a month and two weeks a year(I know it sounds like the reserves).
These are my specific question:
1) What is the average cost in the U.S. to have Solar Panels installed?
2) What is the average cost in the state of Hawaii to install Solar Panels?
3)Is this a worth while venture? (There's a good chance i'm going to ignore this one anyways LOL!)
4)How long does it take to install a photovoltaic solar panel?
5)How long does it take to install a hot water solar panel?
6)Besides the obvious, what permits are needed to get our start?
7)What education or Cert. is needed?
8)Average time to start up?
If there is any other information you believe pertinent to this subject that I didn't ask directly, please share. Thank you for your help in advance!
