Technical FAQs 4

Can solar panels be installed on a sloped roof?

As well, solar panel installations on sloped roofs can act to trap snow that otherwise may have been considered to slide off the roof structure. Finally, roofing systems installed in new buildings are typically designed to outlast or at least match the average life of the new solar PV system which is about 25 years.

Do rooftop solar panels affect a building?

The larger the surface area required to support the PV system, the greater the potential impact on the building structure. The use of rooftop solar panels increases the superimposed dead load (SDL) of the roofing system and can have varying impact on a building depending on what material is being used for the structural system.

Why do solar panels fail on a roof?

Depending solely on the roof membrane to secure the PV system can lead to premature failure of the roof. Sufficient Clearance for Maintenance: Ensure that solar panels provide sufficient clearance around all roof areas, including mechanical units and drains, to allow for necessary maintenance and future repairs.

Should I install solar panels on an older roof?

Consider Installing a New Roof: Installing a new roof that lasts as long or longer than the expected service life of the solar array is usually the most prudent decision. Installing solar panels on an older roof is not recommended, as it will likely need to be replaced before the PV system.
