Photovoltaic Modules

A solar PV system consists of photovoltaic panels comprised of a group of photovoltaic cells made from semiconductor materials. When a photovoltaic panel is exposed to light or heat, energy is transmitted through the photons to the semiconductor, releasing electrons of its atoms. The flow produced by these electrons creates a Direct Current ("DC").

When the modules/systems are connected to the network, the Direct Current generated may: (i) be directly used; (ii) be stored in a battery; or (iii) be transformed into Alternating Current ("AC") through an inverter. Unlike DC, AC can be used to supply ordinary household devices. Normally production costs and prices are expressed in watts produced when sun light is maximum, ie watt peak (Wp).

The most frequently used semiconductor is crystalline silicon, which is available in two basic forms: Mono-crystalline and poly-crystalline silicon. The difference between these forms basically lies in the size of the crystals inside each of the structures, which in turn leads to different electrical characteristics when exposed to the light.

The photovoltaic solar energy systems can be connected to a transmission and distribution network ("on-grid") of electricity adding the electricity produced by the photovoltaic installation into this system. They are generally installed on commercial and residential roofs, or ground mounted in areas with high solar irradiation levels, as part of larger solar energy installations. They can also be used without being connected to the network ("off-grid") to supply electricity to isolated areas where a grid connection is not possible.

The Company produces four series of photovoltaic modules (S5M Series, S5M+ Series, S6M2G Series and S6P2G Series) and various types of panels in each of the series. Solaria modules power range goes from 185 Wp up to 250 Wp and they use both poly-crystalline and mono-crystalline solar cells. These products are manufactured according to Standard specifications for use in installations connected to the grid and for their use in solar energy systems in residential, commercial and industrial applications not connected to the grid
