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.

Plug And Play Will Make Your Day

Sweet Spot Solar primarily works with Enphase micro-inverters. These high-quality micro-inverters have a conversion efficiency of more than 96%, are plug-and-play for ease of installation and future expandability, and come with an industry-leading 25 year warranty.

They look like this and each solar module has one micro-inverter connected to it. All without batteries and nothing in your house except an extra breaker in your breaker box!

When combined with Canadian Solar 280 Watt monocrystalline modules, or equivalent, you will have a solar array that performs flawlessly with little maintenance.

We are installing a new array on Gabriola Island right now, so feel free to connect with us if you're in the area to see how all of this works first-hand.
