We're on Long Island. This area has good and bad years when it comes to sun light, however, the stats are well documented.

We definitely use more power (about 3.2 MW/year) than a solar panel project will generate (about 1.4 MW).

Thank you for your thoughts.

A life of 20 years is probably about right - but verify based on the technology you intend to use.

You should include the cost of disposing of the cells when their useful life has expired.

On the other hand, all of the Solar bankruptcies may make obtaining solar panels at a steep discount possible. So you may be able to snag a lot of capacity for a song.
