Frequent Questions
Most common questions about Solarise solar PV systems
Renewable energy generation provides an excellent return on capital investment. On average, you can see a return on your investment in as little as 4 years of a Solarise installation.
Solar panels are generally self-cleaning, especially if positioned at an angle of over 15 degrees. We advise that Solarise systems be visually inspected once a year and cleaned if necessary.
Solarise panels have a range of frames, mounts and fixings, which means that whilst the south-facing roof is preferred, north-facing roofs can still benefit. The Solarise system can be installed on any roof orientation and still achieve electricity generation targets.
This will depend on several factors, such as the building’s geographical location, orientation and pitch. Your Technical Manager will carry out detailed surveys and reports to calculate the expected energy savings and financial benefits of your Solarise installation.
The bespoke frame and mounting options ensure the Solarise system can be installed on any Garland UK waterproofing system. This includes bituminous membranes, metal profiles, cold-applied liquid coatings, or green roof systems.
Solarwatt panels are guaranteed for up to 30 years and are expected to generate at least 97 % of the measured minimum output in the first year. They will not decrease by more than 0.35 % per year in the 29 following years.
