Previous chapter: Contractor #2
|Contractor drilling post holes for ground mounted solar|
We were able to push our annual consumption from 8,800 kWh to 12,500 kWh in the space of three months. It’s amazing how you can squander energy when you put your mind to it!
While this was going on, we again looked at the companies from whom we’d received plausible quotes, but weren’t convinced. I happened to spot one of those corrugated plastic advertisements you see stuck into the ground on traffic islands.
Armed with an electric bill that justified the larger system we wanted, we called the number. Long story short, they were credible, provided good references, and we visited a nearby installation that was virtually identical to what ours would be. It was rock solid and looked good. Their price was lower than anything we’d seen before, no doubt because the cost of solar panels has been coming down steadily for quite a while.
It was a matter of weeks before the permits came back and the equipment started to arrive. Construction, from start to finish, was probably about three weeks. While this was going on, our meter was swapped out for a two-way digital unit to measure imports and exports of electricity.
The end result was solid, a highly professional job. One minor issue was the cutting of our drywell outlet pipe when they dug the trench for the cable. I had delineated it to avoid such an eventuality, but that’s just it, they happen eventually.
We went live the afternoon of June 23, 2011, generating the princely total of 4 kWh.
