Hi,
just want to say hello to everyone and really appreciate having a site to kick around solar projects and such. Would like to hear comments about using the PVWatts website for system sizing and Google Sunroof for panel placement.
My neighbor wants to add a Grid-Tie solar system to his house roof and using the PVwatts website and the Google Sunroof estimates a system between 8.6kw and 9.3 kw would work for his 12,200 kwh annual load. Bids from multiple companies spec the system size should be between 11.2kw and 15.1 kw however and panel placement is different for each company.
Thanks for your thoughts.
