Now that we are racing to the summer equinox, the added hours of sunlight have been a big boost to our solar energy production.
Our 22-panel system was turned on in mid-November and struggled to generate much electricity at all. I certainly expected less output in winter, but it was almost none on some days. The panels were often covered in snow and ice, and as it is a roof-mounted system, there isn’t any safe way to clear them.
Last month things really took off and the electricity bill that arrived today was only $34, and there is even a 160 kWh credit that will carry forward to next month! Up until this bill, our net metering credit was for the full amount generated because it never came close to what we used; on our January bill, the credit was $3.74!
The process to hook up to the Maritime Electric grid was a bit mysterious, and there wasn’t much explanation from them or my system installers on how the billing would work. All I knew was that we received a second meter to measure the outflow of solar energy from our panels into the grid, that amount would be deducted from the original meter that we have always had, and we would pay the difference.
I now see our net metering credit will only be for up to what we actually used from the grid and not the entire amount that went through our second meter. We will, therefore, never have a $0 bill, which makes sense as we would have to pay the service charge to stay connected to Maritime Electric. The credits will build up over the summer and be used up in winter.
Our average monthly electricity usage since we moved into our house in 2002 was 605 kWh. It went up to an average of 850 kWh the first three months of this year with the addition of our EV (and I was driving to Summerside a lot), so to have it drop down again is really encouraging! I haven’t been driving much since March 13, so have only used 148 kWh to charge my Bolt EV compared to 459 kWh the previous month, which would explain some of the reduction.
The other drop in our bill is because the electricity from the panels goes through the house panel first and what is left over goes through our second meter and into the grid. Our solar system produced 897 kWh of electricity over this last billing period, and the second meter received 617 kWh, so we used 280 kWh of direct electricity that didn’t make it to the second meter, and that we didn’t pay HST on! I try to charge my car during sunny days to be able to drive on sunshine, and yes, I do sing a modified version of the Katrina and The Waves song when I’m doing it!
So if you get a solar system in the winter, do not despair. Someday the sun will shine and you will see the benefits. As with everything these days, just hold on and things will be brighter.
