If you have any questions or concerns about our services, here are some common inquiries we receive.

What is the lifespan of a solar panel?

Solar panels typically have a long lifespan, lasting between 15 to 20 years. However, their efficiency may reduce over time due to wear and tear, but they can still produce energy beyond their estimated lifespan, albeit at a reduced capacity.

How much maintenance do solar panels require?

Solar panels require minimal maintenance. It's recommended to clean them a few times a year to remove any accumulated dust or debris which could affect their efficiency. For PV panel systems, we offer post-installation support and maintenance to ensure they're always in top shape.

Can solar panels work on cloudy or rainy days?

Yes, solar panels can still generate electricity on cloudy or rainy days, although not as efficiently as on sunny days. The panels work by absorbing light, not heat, so they can still produce energy even under overcast conditions.

What happens if my solar panels produce more energy than I use?

If your solar panels generate more energy than your house consumes, the excess power will be fed back into the grid. Depending on your energy provider and local regulations, you may be able to earn credits or get paid for this excess energy.
