Chris is exaggerating the benefits, without battery storage it's not a big saving only when the sun is out.
Most of us use more energy after the sun goes down.
You need a battery storage system for residential efficiency this would add about $7,000-$12,000 to the cost of a system.
Then you can cut the cord to the utility.
So is the panels cost say $25K add another $10K or $35K for complete system.
Chris says such battery systems are too expensive. (his words)
Without batteries it's like car without tires
Chis uses Hanwha Q Cells solar panels (A korean company with a plant in Ga) they come with a 12 year product and 25 year linear performance warranty.
The linear performance warranty guarantees the performance of a panel will stay above a specified degradation rate (the decline in output that all solar panels experience)
