Maintenance

1.Is the energy produced affected if the panels get dirty?

Usually any dust or dirt washes off the panels when it rains, if the panels are installed on a roof of at least 15 degrees. In extreme cases dust may cause a power reduction of about 10%.

2.How long do solar panels last?

Solar panels have a manufacturers warranty of 25 years and a working lifetime of 40 years and beyond.

 3.Do panels need cleaning?

Not as long as they are mounted at a steep enough angle (>20°) so that the self-cleaning glass works.
