Soltech has developed a range of standard Off-Grid Modules & Systems for stand-alone and Off-Grid applications. The components are best chosen to ensure reaching the highest qualitative performance of the system. All products are subject to a continuous optimization process and very stringent quality checks. Additionally to our standard portfolio, our team of experienced engineers can develop all PV systems based upon your specific requirements.
Photovoltaic involves the direct generation of electricity from light by using a semi-conductor material which can be adapted to release electrons.
The most important parts of a PV system are the cells which form the basic building blocks, the modules, which bring together large numbers of cells into a unit, and, in some situations, the inverters used to convert the electricity generated into a form suitable for everyday use.
All PV cells have at least two layers of semi-conductors, one positively charged and one negatively charged. When light shines on the semi-conductor, the electric field across the junction between these two layers causes electricity to flow, generating DC current. The greater the intensity of the light, the greater the flow of electricity
A photovoltaic system does not need bright sunlight in order to operate. It also generates electricity on cloudy days, with its energy output proportionate to the density of the clouds.
