Aimee bought me a Cuisinart Food Processor for my birthday. Since she was so thoughtful I bought her an early birthday present. A solar electric generating system. The one thing we have an abundance of in Arizona is sunshine. We already have a solar pool heating system to harvest some of that energy. That system pumps the pool water onto the roof of the house to be warmed in black mats of small plastic lines. The heater means we can open the pool a month or two early.

We have lots more space on the roof, so I thought Aimee would like to go “green” and add some solar cells. A crew of three came to the house and over the course of four days installed 34 solar panels on the roof, enough to generate a years worth of electricity for us. The production has been remarkably steady in this first week of operation. We made exactly 41 kilowatt-hours each day. That is more than twice what we need right now, but the local utility is storing it for us and will give it back this summer when we turn on the A/C and need more than we can make.

I like the idea of reducing our impact on the environment but I have to admit I like the economics even better. Because my fellow taxpayers are so generous they subsidize over 75% of the cost of the system. All things considered solar is going to cut our electricity costs in half. Plus we will never see a price increase from the electric company.

Hmmm. I am thinking Aimee might like one of those new electric cars for her next birthday.
