Get credit for being sustainable

During the month of July, one of our medium-sized solar arrays generated a credit with BC Hydro of 448 kWh! It only used extra energy from the grid on 2 days. Email info@sweetspotsolar.com to learn more about doing this yourself.

Another illustration of how net metering works

Here's another example from one of our solar arrays of how net metering works. On June 28, 2017, this array composed of 23 modules on a 2200 square foot house produced a credit of 15 kWh. In other words, it sent 15 kWh of electricity into the grid and the smart meter recorded that surplus generation.


There are some features of this graph worth noting. First, between Midnight and 7AM the house pulled electricity (consumed) from the grid. By 8AM the house's solar array began producing more electricity than the house used and it continued to do so until 6PM. Second, the magnitude of the bars going down (credit) peaked at solar Noon, and the distribution of energy production follows a normal curve shape on a sunny and clear day - assuming that electricity consumption in the house is constant.

This array has already generated a surplus of 136 kWh for the month of June that will roll into July. A surplus in July will roll to August, and so on. With net metering, and a large enough solar array relative to consumption, you can create a substantial credit to reduce your winter billing. This is why solar works well and also why batteries are not required.
