Solar PV

Solar Photovoltaic Panels (PV) are available in numerous varieties, sizes, and power outputs. Most commonly used are mono-crystalline lenses, which typically have a black frame. Panels with a black back are also available and gaining popularity as they can provide a more aesthetically appealing finish, particularly on residential properties.

Above Roof Mounting

Traditionally, panels were installed on top of the roof covering (tiles, slates, or metal) using a mounting system designed specifically for each form of roof. This is typically the most economical technique for retrofitting a solar system.

Building Integrated

BIPV (Building Integrated Photovoltaic or BIPV) is a technique that allows solar panels to be integrated into the roof’s structure. Using this method, they serve as the watertight covering in lieu of tiles or slates. The installation of tiles and slates around them creates the illusion that the solar panels are embedded in the roof. This provides a high-quality finish that is frequently flush with the roof covering.

Flat Roof Mounting

If you have a large flat roof area, you can also install solar panels on specially designed mounting systems that enable the panels to be installed at an angle facing south. These mounting systems may be attached directly to the roof structure or ballasted. Not every level roof is suitable for this system.

Store your excess solar power

If you intend to install solar PV panels, you should also consider installing a battery storage system to retain any excess electricity that your solar PV system generates during the day for use at night and in the evening.
