Our customers have had solar panels installed for multiple reasons. Many customers are focused on reducing or eliminating their hydro bills. Imagine freeing up hundreds of dollars each month! Other customers have solar panels installed to reduce their carbon footprint, as they have a great sense of commitment to the environment and future generations. Some customers install solar panels for the investment into assets that add value to their home. Studies have show that solar panels can increase the market value of homes by 4.1%*, and in a housing market like Vancouver, that’s a significant increase. Many customers also install solar panels to stabilize their electricity costs. With solar panels, you protect yourself against the increasing costs of electricity. We know that electricity costs will continue to rise each year. With our demand for electricity in BC due to adopting electric vehicles, heat pumps and other devices that increase our overall consumption of electricity, we will place pressure on hydro infrastructure that may struggle to keep pace with our consumption.
