So only the 4 winter months here should be abridged or have excess solar power (4 times as much) as normal. This is with a insulated house etc.
December through March is when I buy electricity. I now have documented how KWhs or BTUs I need to eliminate the massive heating load. Last August the Governor made a new deal for better pricing of the electricity I deliver to the grid. This year I will see a much higher income for my excess summer production. I will re-invest this into more production.
The real problem with solar is only a few months of the year. Isolating the problem of energy production and storage to only those months demonstrates how close we are to a new energy future. My next step will be solar thermal install. I want a more passive method for heating as a backup.
My location 42.73226° N, 73.19623° W. I can provide five years of production data if people are curious.
Solar is just awful for our climate, since we produce most when we use the least, which you can see in the quite extreme negative prices for electricity we've already seen this year... And it's not even summer yet.
In 2021 the array delivered KWh in roughly these groups 8 days over 300 KWh. 96 day over 200 KWh. 84 days over 100 KWh. 110 days over 30 KWh. 20 days over 10 kWh. 15 days at 0 and the rest between 1 an 9 KWh.
If I had the install to do over I would have prioritized a steep incline. The location I choose was easy to install but the panels angle is less the 15 degrees which collects snow.
