We had Goldwater Solar Services install solar panels on our new house in Markham 6 years ago. Now that we need service, we cannot get a reply from this company. Very poor customer service. Be careful whom you choose for your solar panel needs.
Had solar panels done. They worked efficiently and quickly. But afterward, as part of the process we expected a request sent for them to be connected to the grid so we could get the credits from Toronto Hydro. We were assured they would. That was in April. It is mid-July now. Had to call Toronto Hyd…

This calculator sizes a solar system from your electricity use. Your monthly bill, divided by the average Ontario electricity price, gives your yearly use; Toronto's sunshine (1,163 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 Ontario pay installers. Payback compares that price with what the panels save at Ontario 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.
