Everything You Need to Know Before Making the Switch to Solar in BC
🌞 Why More BC Homeowners Are Going Solar in 2025
British Columbia is rapidly transitioning toward renewable energy, and solar power is at the forefront of this movement. With electricity rates increasing, generous government incentives, and a growing awareness of climate change, more homeowners and businesses are investing in solar energy than ever before.
But if you're thinking about making the switch, you likely have some important questions:
This comprehensive guide will answer all your questions and walk you through everything you need to know before installing solar panels in BC.
☁️ Can Solar Panels Work in BC’s Cloudy Climate?
One of the most common concerns about solar energy in British Columbia is whether it works in cloudy and rainy conditions. While it’s true that BC experiences a lot of overcast days, this does not mean that solar power isn’t viable. In fact, solar panels remain highly efficient even in low-light conditions.
How Solar Panels Generate Power on Cloudy Days
Solar panels don’t just rely on direct sunlight; they also capture diffused sunlight, which is scattered by clouds and still provides energy. Even on a completely overcast day, solar panels can generate between 10% to 25% of their usual output.
Here are a few key reasons why solar power is viable in BC:
✔ Germany is a global leader in solar energy, despite receiving less annual sunlight than Vancouver. Over 50% of Germany’s electricity comes from solar!
✔ British Columbia experiences long summer days, which help offset lower production in the winter months.
✔ New high-efficiency solar panels (like monocrystalline panels) are designed to maximize energy generation even in low-light conditions.
Solar Energy Output in Different BC Cities
The amount of electricity solar panels can generate varies by location. The measurement used is solar irradiation, which calculates the kilowatt-hours (kWh) of solar energy produced per kilowatt (kW) of installed capacity per year.
| City | Annual Solar Energy Output (per 1 kW system) |
|---|---|
| Kamloops | 1,200 kWh |
| Kelowna | 1,150 kWh |
| Victoria | 1,050 kWh |
| Vancouver | 1,000 kWh |
| Prince George | 950 kWh |
💡 Example: A 10 kW solar system in Vancouver will generate ~10,000 kWh per year, which can offset most household electricity consumption.
🔢 How Many Solar Panels Do You Need?
Step 1: Check Your Home’s Energy Consumption
The first step in determining your solar panel needs is to check your BC Hydro bill to find your monthly electricity usage, measured in kilowatt-hours (kWh).
Formula to Estimate Solar Panel Needs
🔹 Annual Energy Use (kWh) = Average Daily Usage × 365
🔹 Number of Solar Panels = Annual Energy Use ÷ Panel Output (400W) ÷ Efficiency Factor
Example Calculation
A BC home that uses 10,950 kWh per year would need approximately:
🔹 10,950 kWh ÷ 400W ÷ 1.0 (efficiency factor) = ~27 solar panels
💡 Homes with shading or east/west-facing roofs may require extra panels to compensate for lower energy generation.
Step 2: Assess Your Available Roof Space
Each solar panel takes up about 5.5ft x 3.3ft (1.7m x 1m) of space. Here’s a rough estimate of how much space different system sizes require:
| System Size (kW) | Number of Panels | Required Roof Space (sq. ft.) |
|---|---|---|
| 4 kW | 10-12 panels | 170 – 200 sq. ft. |
| 6 kW | 15-17 panels | 250 – 300 sq. ft. |
| 10 kW | 25-27 panels | 400 – 500 sq. ft. |
| 15 kW | 37-40 panels | 600 – 750 sq. ft. |
💡 Limited roof space? Consider using high-efficiency 450W+ solar panels to reduce the total number required.
