Topic tags/keywords: solar energy power question

I’m considering having a PV type solar system installed for my shop electricity and possibly my home power. Does anyone out there have any experience with this type of stuff?

My company has installed these systems and I have worked on a few.
The cost is really high and the gain is marginal unless you qualify for some type of subsidy.

Most professional systems aren’t really what most people think.
They feed power into the grid and you get paid for it.
You still have to connect to the grid and pay for what you use.
If you install a large enough system, sometimes you make more than you use.

Here in Tennessee, the TVA (our government controlled power company) had a program called “Green Power Switch” where they would pay for a large portion of your installation if you jumped through all the correct hoops, filled out reams of red tape, and had the correct “friends” in government (wink, wink). I know people getting a check for $2000 a month for power generated by a PV project that cost $200,000 to build. But they only had to pay $20,000 for the system out of pocket.

Isn’t govmint great. Guess who really foots the bill for this stuff.

At any rate, a typical panel is about 40” x 60” and weighs about 40 lbs.
This panel will have an output of about 30 volts and 250 watts.
These panels cost about $250 to $300 each
So, a 25 KW system will cost about $25,000 just for the panels.

The inverter has to be approved by the local power company.
The wiring of the system has to be done by certified installers.
The inverters can add another $10,000 and combiners and wiring another $10,000.

Usually, the cost of the system can be paid for in about 20 years from the power it produces.
The systems have a life expectancy of about 25 years.
