FAQs

The size of your home, your roof’s physical space, and the power you consume every day or every month will determine the number of panels you will need. Different people have different power needs. Also, the size of a family is different from home to home.

The simplest way to know how many panels you need based on power consumption is by multiplying your home’s hourly power requirement by your area’s peak sunlight hours. Then divide the results you get by the wattage of the solar panels to know how many panels will be enough for your home. To get a range, use low wattage panels and high wattage panels.

Yes, it is possible to oversize your solar system to up to 33%, which is the maximum limit. This is according to the CEC Solar PV Guidelines. If you exceed this limit, you will not get any rebates from the government. You should also ensure you use the best quality inverters, and the system should be installed by CEC accredited professionals only.

Yes, battery storage is critical because it helps you store excess power produced by your panels. The power comes in handy when the grid is down due to limited sunlight, especially during winter. With enough solar energy in your batteries, you can go off-grid and enjoy lighted nights when the climate is not favorable.

The ideal life of solar panels is approximately 25-30 years. After this period, their efficiency goes down, and they may not be reliable. During the first 10-12 years, the efficiency of the panels may decrease by 10%. After 20 years, their efficiency will decrease by 20%. Once the panels’ productivity decreases below 80%, you will need to install new panels for reliable solar power.
