Today, we're at the solar system construction site.

A 20-kilowatt solar system will power a customer's 10-kilowatt boiler, as well as air conditioning, lighting, and other equipment. We're using

18pcs 550-watt generator panels, a 20-kilowatt inverter,

a 20kilowatt battery, an MPPT controller, and a combiner box. We'll install the equipment in our equipment room

and the solar panels on our skylight-tile roof.
