The First Visit:
Larry visited few days later and explained the program to me and asked me what I was looking for in PV system? Answer: As big a Photo Voltaic (PV) system that could fit! He also brought his electrician with him and we looked over the house.
As I think is common with most solar contractors, they sub out work to roofing companies and electricians to do the work related to their trades. The roofers set the mounting stanchions and rails that support the PV panels and the eletricians install the panels and complete all the wiring. The solar contractor coordinates ALL the paper work, applications and various sub-contractors.
The electrician verified our house electrical could support the installation and Larry looked at our roof to be sure that it would be a good candidate. Based on house position, roof slope, obstructions and other details, he would calculate our home’s “Solar Resource Fraction” to verify that we qualified for the incentives and credits. It turned out our Solar Resource Fraction was 90% and we needed to meet at least 75% to qualify for the Energy Trust of Oregon (ETO) Solar Incentive.
