We decided to install a photovoltaic system at the end of last year, but it didn't get installed until last week. I don't know how many of the rest of you have gone through this process. In northern California we get electric power from PG&E. There's a tiered rate system. The lowest rates are $0.11/Kwh. Once you use more electricity than the base level, you pay a higher rate. 101-130% of the base rate is $.12/Kwh, 131-200% of the base rate is $0.22/Kwh and 201-300% of the base rate is $.32/Kwh. I don't know about you, but it seems like all the gadgets and electronic toys we have really expand our use of electricity. Our system consists of 10 Sanyo 205 solar panels, designed to produce 1.81 KW. It's small relatively speaking, but it was the only pure play we had to collect the sun's rays without shading effects. The roof we placed the panels on faces south. Our site wasn't condusive to ground placement so we ended up with this configuration from Ready Solar, a start up based in Portola Valley, California. Ready Solar supplied the panels, inverter and frame(patent pending). The installation was done by RA Tech Solar from Gilroy, California. Mark Thompson from RA Tech Solar is a really experienced guy and we were lucky to have him on the job. Shake and tile roofs aren't easy to do and he had to make frame modifications on the fly, something he did with ease. We liked this design because the panel supports don't show. This was especially important because the roof the panels are located on are in the front of our home. Now that everything is installed and the permit signed off, we have to wait for PGE to install a new meter to record the output. Once they do this, we'll sell the electricity produced back to PG&E. We expect the system to reduce our electricity costs by at least one-third, eliminating higher usage costs. It's going to be a fun experiment and perhaps we'll make a small dent in the global warming crisis.
