Typical Solar PV System Components
The solar PV panels convert light into direct current (DC) electricity and come in various shapes, sizes and power outputs.
The three main types of solar panels are monocrystalline solar panels made from single crystal silicon cells. Polycrystalline solar panels are made from fragments of silicon crystal that are fused together. Thin-film solar panels are manufactured from layers of semi-conducting materials such as silicon, cadmium telluride and copper indium gallium selenide.
All panels available on the market today will differ in efficiency, so it is important to work with a solar PV partner who can specify the best system for your building and energy requirements.
Connected to the PV panels via DC cables, inverters convert DC into alternating current (AC) electricity for use in buildings. Inverters maximise the PV output whilst minimising power losses. Depending on the number of solar PV panels installed or the required kWh generated, the size of the inverter will differ.
Frames and Fixings
Solar PV panels are typically mounted horizontally or vertically on a building’s roof or facade to achieve the optimum energy generation for your building. Various frames and fixings are available to choose from to secure the PV panels to a roof, wall or surface. Most standard solar PV panels are supplied with an aluminium frame, which can be securely attached to prefabricated rails that are mechanically fastened to the existing roof structure.
