Although rooftop solar power has become very popular, a whole home battery alone makes enormous economic sense under the right conditions, and usually is the better investment.
CLEP can pay $1000/year for a $10,000 battery — good, because 10 years is the warranty period.
BSI also believes whole-home batteries belong in every home, because they empower customers to withstand extended power outages, provide electricity reliability, and promote and utilize renewable energy and sustainability.
The best solar investment is Community Solar — placed on the utility side of the meter but jointly owned by many consumers — which involves no batteries at all.
Many homeowners with enough batteries and on-site solar to be self-sufficient are choosing to leave the grid altogether, i.e., grid defection; but CLEP arrests and reverses grid defection because CLEP richly rewards such customers for use of their equipment, if grid connected.
