Solar panels in Coquitlam, British Columbia

Coquitlam produces about 980 kWh per kW of panel per year. That is 17th of the 19 British Columbia cities we serve – well behind Penticton’s 1,270 and below Vancouver’s 1,010. The cause is geography rather than anything fixable: Coquitlam sits against the mountain slopes at the head of the Fraser Valley, which lifts and wrings out incoming Pacific weather, so it collects noticeably more cloud and rain than the cities further out on the delta.

So why does solar still work here? Because what matters is not how much you generate but what the generation displaces. BC Hydro charges a two-step residential rate – 11.87 cents per kWh for the first 675 kWh a month, 14.08 cents for everything above it. Solar offsets your most expensive kilowatt-hours first. A large Westwood Plateau or Burke Mountain house running electric heat sits deep in Step 2 for much of the year, so each generated kWh is worth the higher rate rather than the average one. That is why a 7 kW Coquitlam system still returns around $1,790 a year on an 11 to 14 year payback, despite the production ranking.

This is the choice that matters most for a Coquitlam quote in 2026, and it is not obvious.

BC Hydro closed 1:1 net metering (Rate Schedule 1289) to new customers on 1 July 2026 and moved new applicants to a fixed export rate of about 10 cents per kWh (RS 2289), approved by the BC Utilities Commission on 24 March 2026. The trap is the interaction with the rebate: taking BC Hydro’s solar rebate moves you onto the new export rate. Installing without the rebate may keep you on 1:1 credits, which BC Hydro holds for 10 years from the original service start date.

Which is better depends on how much you export, and Coquitlam’s profile pushes the answer in a particular direction. Lower production and larger, heat-heavy homes mean a Coquitlam system self-consumes a high share of what it makes and exports relatively little – and the value of 1:1 credits scales with what you export. For many Coquitlam homes the up-front rebate is worth more than a decade of credits on a small surplus. That is the opposite of the advice a high-production, low-consumption home should get. We model both against your actual bill rather than assuming.

Coquitlam’s two big residential areas present almost opposite solar problems.

Westwood Plateau was built out through the 1990s and finished around 2006, and it was developed into standing forest. Mature conifers on and around the lots are the single most common reason a Coquitlam roof underperforms its estimate – and unlike a rainy climate, shading is not evenly distributed. It moves across the roof through the day and shifts seasonally as the sun angle drops. A string inverter loses disproportionately here, because shade across one panel drags down everything on that string. We survey for it before quoting and specify module-level electronics where the canopy warrants it.

Burke Mountain is the opposite case. It is Coquitlam’s current development frontier, so the housing is new: simple roof planes, modern trusses, current electrical service, and no mature tree canopy yet. These are among the easiest and cheapest roofs to work with anywhere in the Lower Mainland, and worth doing before the surrounding planting matures.

A typical Coquitlam installation is around 7 kW. At roughly 980 kWh per kW, that produces about 6,900 kWh a year – enough to cover most of a mid-sized household’s consumption without generating a large surplus for export.

The annual saving works out at about $1,790, and the payback lands between 11 and 14 years. Both figures assume the generation displaces Step 2 electricity at 14.08 cents rather than the Step 1 rate, which is the realistic case for a larger Coquitlam home on electric heat. BC Hydro has raised rates 3.75% in each of the last two years, so the annual saving grows over the life of the system while the cost is fixed at the day you install. Panels carry a 25-year warranty, so the years after payback are the return.
