What did a 4KW Canadian Solar panel system cost you, inclusive of warranty? How large a battery system? Also, did it have a cutoff that disables the solar panel system if you lose utility power?
16 panels installed, Permitted, micro-inverter tech, with hard mounting rails (through tile), not the easy hangars most people install with cost me out the door 16K$. Then I got a 30% tax rebate from the feds. Everything has 25 year warranty on it from manufacturers.
This is a grid tie system. No batteries. In the city we're not concerned with 100% off grid solutions. PG&E our provider has contracted with me as a power provider. So excess power is banked and credited over a period of 12 months.
Also, the system is easily extensible. I'll be adding another 3KW for another tax write off this year. No additional inspections required as the micro-inverters don't need a central monolithic inverter which need to be increased as the number of panels increases.
Thanks! So, I guess the two really interesting follow-on questions are - how many kWh/year do you expect to generate, and how much is PG&E paying you per kWh?
