My goal as a senior energy consultant is to design a solar PV system for your home that offsets 100% of your annual electric usage and 100% of your monthly PG&E electric bill.  With a traditional PV system, if the solar panels produce more solar energy than is needed, the surplus electricity is sent to the electric grid for net metering credits. Private rooftop systems are designed so that all of the electricity produced by the PV system is used in the customer's home and the homeowner is not compensated for exporting energy to the grid. 


The contract price for the private rooftop system that I designed for Villa Bonita's 12 condominium owners is $139,916. After applying the 26% ITC of $36,378, the net cost of the solar PV project was $103,538. Total savings over the 25 year warranty is $359,091. Villa Bonita condomimium owners who have an average monthly PG&E electric bill between $75 and $100 will pay less than $55 per month. Condominium owners who have a PG&E electric bill that averages between $100 and $125 per month will each pay less than $80 per month.
