Solar Photovoltaic (PV) technology allows to convert sunlight directly into electricity. Here is how it works.
“Photovoltaic” comes from the process of converting light (photons) to electricity (voltage). PV technology was discovered in 1954 when scientists found that silicon (an element contained in sand) created an electric charge when exposed to sunlight. Today, Solar PV is a proven technology which provides electricity to millions of homes and businesses worldwide.
Our solar PV systems are made in Germany and include the following components:
PV modules. Modules (or panels) are installed on the roof and mounted on aluminum rails to create one or several arrays. A typical house in Seychelles requires 12 to 20 panels to cover its electricity requirements, depending on the number of appliances such as cooker, refrigerator, TV, lighting and air conditioning. A typical PV modules measures 1.7m x 1.0m and weighs 18kg. PV modules produce Direct Current (DC) which is fed into an inverter.
Tip. It is important to consider the state of your roof before you invest in a PV system. Most residential roofs are supported by wooden beams, which are designed to support some additional weight, usually equivalent to a small PV system. Larger systems need to be assessed on a case by case basis. Another important consideration is the lifespan of the underlying roof, since PV modules are designed to last 30 years. If your roof is old, it is advisable to have it replaced before installing a PV system.
