The solar system was leased so there was no initial cash outlay, and the tax benefit is taken by a for-profit company. The lease is structured so that, during the seven-year term our total annual cost of electricity will be a little less than our PG&E bill might have been if we did not have the solar system. At the expiration of the lease there will be a residual value estimated at approximately $67,000 that we must pay to the leasing company in order to fully own the solar system.
