just about all the companies i talk to have it around 7.5 kw system getting me into baseline lowest area and for the lease (the huge fed incentive is no longer active)its about $170 to $200 a month depending on the company. nothing down. 20 year lease. buy out around 20k due to we just moved in and its new construction.
so instead of paying sdge $420 a month I will now pay $167 for the solar and maybe sdge $30 or so for overages on high use days. Just about all the companies have the same product too. Even with the lease buyout they maintain for all 20 years.
payment would have been $43 a month for all of this if the fed program was still active.
