Solar Photo-voltaic Panel / Module

Solar Photovoltaic (PV) Technology

The variety of solar power technologies available are compared on a scale of efficiency, price, durability, and flexibility, depending upon the need of the project. PV solar technology generates power because substances like silicon generate an electrical current when they absorb sunlight, in a process known as the photovoltaic effect. Like semiconductors, solar PV technology needs purified silicon to get the best efficiency, and the price behind PV solar manufacturing is often driven by the crystalline silicon purification process. We offer a range of Solar PV Modules with power ratings of various manufactures of Mono- and Poly-crystalline Silicon varieties.

Monocrystalline Silicon Solar PV: Most Efficient

Generally, monocrystalline silicon solar PV is the best technology to deliver efficiency, as measured by wattage output related to the panel’s size. But this efficiency can come with costs.

Monocrystalline solar is made by growing a single crystal. Because these crystals are usually an oval shape, monocrystalline panels are cut into the distinctive patterns that give them their recognizable appearance: the sliced silicon cells expose the missing corners in the grid-like structure. The crystal framework in a monocrystalline is even, producing a steady blue color and no grain marks, giving it the best purity and highest efficiency levels.

Polycrystalline Silicon Solar PV:

Polycrystalline solar is made by pouring molten silicon into a cast. However, because of this construction method, the crystal structure will form imperfectly, creating boundaries where the crystal formation breaks. This gives the polycrystalline silicon its distinctive, grainy appearance, as the gemstone type pattern highlights the boundaries of the crystal.

Because of these impurities in the crystal, polycrystalline silicon is less efficient when compared with monocrystalline. However, this manufacturing process uses less energy and materials, giving it a significant cost advantage over monocrystalline silicon.
