A year in the life of a solar array on Gabriola Island

On August 23, 2016, a new solar array was commissioned on Gabriola Island. This array is composed of 28 LG310 Watt modules and Enphase M-250 micro-inverters. It was installed on this stunning garage.



Sweet Spot Solar estimated annual production for this 8.68 kW DC array at 9765 kWh/year under ideal conditions on an annualized basis.

For the year, the array generated 9290 kWh. For this year, the longer than normal winter combined with several weeks of smoke from forest fires reduced output by 4.87% from our original estimate.


Note the deep drop in production between the months of November and February. This is typical of a solar array at this latitude. During the Spring, Summer, and early Fall a solar array makes lots of extra power that gets banked as a credit with net metering through your smart meter to offset your winter bills. All without batteries!

From an environmental performance perspective, our monitoring software yielded the following calculations.
