Photovoltaic (PV) systems generate electricity from the Sun. PV is ideal for supplying 10% of a building’s energy needs as it is both visually unobtrusive and low-maintenance. PV systems typically comprise of an array of PV modules ("solar panels") which are mainly roof mounted and connected to a bank of inverters that convert the DC electricity generated to AC power suitable for use within the building. Excess electricity which is not used can be exported back to the grid. The PV modules can be mounted in several different ways, and SEI will design a mounting system to optimise output subject to your requirements.

SEI has a great deal of experience with PV systems, as shown by our project listing. We have good relationships with a range of manufacturers, which allows us to design the most cost- and energy-efficient system possible. Our experience also ensures that our installed systems are of the highest quality and compliant to the latest standards.
