Do I need to install a new roof before solar panels are installed?

Solar panels are very durable and should last you around 20 to 25 years. Therefore, you definitely should consider the age of your roof before installing a set. If your roof is more than 20 years old and in bad shape you will want to consider replacing old tiles before installing them.

How often should I clean my solar panels?

If you live in an area that receives an adequate amount of rainfall, then this should be enough to do a thorough cleaning job. However, if you live in a dusty area (dirt roads, highly urbanised areas), then you should clean the panels at least once a month. You can use a high-pressure hose to do the job.

Can you put solar panels on a flat roof?

Yes. Most commercial solar panel systems are installed on flat roofs.  The solar panels are usually mounted on “tilt-racks”, which put the panels at the optimum angle and face them in the right direction.
