hate to leave this review. This is the second time I’ve had to leave a negative review for smart wave. We bought solar panels from a company that sadly is no longer in business called gosolar. The SMA sunnyboy inverter they installed just randomly doesn’t work. I contacted SMA who gave me the run ar…
I signed up contract with Apex Solar Solutions, and I changed my mind after 2 weeks. I called the loan company named Mosaic to cancel my loan. They canceled my loan immediately and I ask them if there are any cancelation fees, they said no cancelation fees. I received an cancelation email few weeks…

This calculator sizes a solar system from your electricity use. Your monthly bill, divided by the average Colorado electricity price, gives your yearly use; Colorado's sunshine (1,595 kWh per kW of panels a year) then gives the system size that covers it, adjusted for roof direction and shade. The installed price is that size multiplied by the price per watt homeowners in Colorado pay installers. Payback compares that price with what the panels save at Colorado power prices, assuming prices rise 3% a year.
An estimate, not a quote. Roof size and pitch, shading, equipment, permits and the installer all change the final price; installers confirm it after a site visit.
