Go Solar With Abbotsford's #1 Solar Installation Company

Solar installation costs range from $2.40 to $3.50 per watt for the most common panel type: monocrystalline. For a typical 5 kW residential system, that puts the total between $12,000 and $17,500, while a larger 10 kW system runs $24,000 to $35,000. In Abbotsford, BC, installed costs average $2.60 to $3.27 per watt, while Alberta tends to come in slightly lower at $2.40 to $3.02 per watt. The final number depends on roof complexity, panel type, permitting fees, and whether you add battery storage. Getting a quote from a local installer is the most reliable way to confirm what your specific system will cost. 

Solar installations fall into four main categories, each built for a different scale of energy demand. 

• Residential systems (5–15 kW) power individual homes. 
• Commercial systems serve businesses and warehouses at 25 kW and up. 
• Community solar lets multiple users (including renters) share output from one array. 
• Utility-scale systems are large grid-connected arrays that can power thousands of homes at once

After 25 years, your solar panels don’t stop working. Panels just produce slightly less power. Most monocrystalline panels come with a 25-year performance warranty guaranteeing at least 80% of their original output by year 25, meaning a system that generated 10 kW at install will still reliably produce around 8 kW. Physical degradation is normally slow and linear, around 0.5% per year on quality panels. At that point, your options are to continue running the existing system, replace underperforming panels individually, or upgrade to newer, higher-efficiency panels, which will likely be significantly more affordable by then. Inverters, which tend to have a shorter lifespan of 10 to 15 years, will likely have been replaced once already before the panels reach that milestone.

Yes, solar panels still generate electricity on cloudy days, as they rely on daylight rather than direct sunlight. Panels absorb diffuse light passing through cloud cover, so output continues even in overcast conditions. You’ll see reduced production compared to a clear day, usually 10 to 25% of normal output, depending on cloud density. Any shortfall is automatically covered by grid power, or by a battery system if you have one installed

The right system size depends on your average monthly energy consumption, shown in kilowatt-hours (kWh) on your BC Hydro or FortisBC bill. As a general benchmark, the average Canadian home uses around 900 kWh per month, and a 1 kW solar system produces roughly 100 kWh per month in BC. So a 9 kW system would cover close to full offset under ideal conditions. Most homeowners start with a 5-10 kW system and scale up based on budget, roof space, and future needs such as EV charging or battery storage. The team at Abbotsford Solar Installations can review your usage data and design a system sized for your home. 

The installation of solar panels is a structured, single-day process for most residential systems. It starts with a roof assessment to confirm structural integrity and identify the best-angled section for sun exposure. Panels are then mounted on a racking system secured directly to your roof joists, wired together, and connected to an inverter that converts DC power to usable AC electricity. From there, your system ties into your home’s electrical panel and, once inspected, connects to the grid for net metering. No major excavation or structural changes are required. Before we leave, we test the full system, confirm output, and walk you through monitoring your production.

Solar batteries aren’t required, but they add significant value depending on your energy goals and local utility setup. Without a battery, surplus electricity your panels produce is sent back to the grid. Batteries are useful if your utility offers net metering credits (which BC Hydro and FortisBC both support). With a battery like the Tesla Powerwall or a comparable lithium-ion unit, that surplus is stored on-site for use after dark or during outages. For homeowners in areas with frequent grid interruptions or high evening electricity rates, a battery can meaningfully reduce reliance on utility power and improve long-term ROI. 

If snow falls on solar panels, it has less impact. Light snowfall clears on its own, and panels are installed at a tilt, commonly between 30 and 45 degrees, which allows accumulation to slide off as temperatures fluctuate. Even under a thin layer of snow, diffused light still reaches the cells, and some generation continues. During heavy accumulation, clearing the panels with a soft roof rake restores full output quickly. In most of BC, including Abbotsford, the higher solar irradiance in winter months, especially on clear, cold days with snow-reflected light, offsets the occasional production dip from snowfall.
