In Toronto there is only daylight for 9 hours in winter

Yes surely some days are cloudy

So some days you get 5% capacity factor, and need some other energy source as well

So it harms the economics of the venture

Look at the profitability of companies building utility scale solar farms, they cost 100 million and the company hopes to get a 10% return and pay a 3% dividend.

They still have to contend with moving parts for tracking the angle of the sun, fans on inverters, contactors, clearing snow, mowing grass, site drainage, tornadoes etc, so sometimes it is not as easy as it sounds

All for a 7%? Why shouldn’t they just buy the s&p 500 and call it a day
