Solar shingles in Vancouver work by replacing traditional roofing materials with thin-film photovoltaic (PV) cells embedded directly into an asphalt-like material. This technology allows the roof to capture sunlight and convert it into electricity through a process where photons excite electrons in silicon layers, creating a direct current. Inverters then transform this into usable alternating current for the home.
For residential structures in the Lower Mainland, these shingles are installed on sloped roofs (typically with a 4/12 pitch) by interlocking and nailing or adhering them directly onto the underlayment. This method mimics standard shingle installation, ensuring the weight is distributed evenly to withstand coastal winds up to 90 km/h. To optimize performance in Vancouver’s specific environment, solar shingles often use micro-inverters to maintain energy output even when partially shaded by trees.
In terms of efficiency, these systems typically achieve 15-20% efficiency and can provide 15-40% annual energy savings. They are designed to be durable against the region’s frequent rain and wind, with a projected lifespan of 25-30 years.
