Solar PV Tech Checklist
Solar Panels are more useful than Granite Counter Tops
When it comes to home improvements the usefulness of an item is often understated. For example, when was the last time someone commented on how beautiful the roof of your house is, or how efficiently the plumbing works? You are more likely to receive kudos for your paint choice or granite counter-top. When considerinng the investment in PV - which is a great technology in my view - consider this checklist.

Complete system manual (spec. sheets not enough)
Power backup options

Dedicated support phone # and email
Pre-defined service package

Monitoring – system monitor as an option should customers wish to have remote monitor located in home
Panels
