SOLAR ELECTRICITY

Grid connected systems

A solar energy system for generating electricity is a major investment. With the proposed feed in tariff law (middle/ end 2009) in South Africa for photovoltaic systems, the solar systems can be particularly profitable.

The photovoltaic installations enable surfaces of public or commercial buildings to be used to generate electricity. Photovoltaic modules can be stylishly integrated in the building façade or in a skylight construction in place of conventional glazing.

Semi-transparent solar cells in some modules are particularly striking as they allow the sunlight to shine into the building and thereby generate electricity. Façades and skylights therefore have an additional active energysaving function.

Stand-alone systems

A photovoltaic stand-alone system can be specially configured according to the customers' energy requirements. The number of photovoltaic modules depends on how long they last and how much electricity the consumer requires.

The direct current generated by the photovoltaic modules can be consumed directly or stored in rechargeable batteries for later use. Storing electricity also means that there is a basic supply for lighting or to keep the fridge running during the night or during bad weather.

The photovoltaic systems allow solar power to be used for various AC and DC electrical devices as well as generator-supported hybrid systems and backup systems for emergency power supply.
