Traditionally, solar modules are made by solar cells with 78*156 mm size. The solar cells are interconnected with ribbons and create strings within the module. Typically, standard PV cell is of 2 W with 8 Amp. current and 0.5 V voltage. It produces about 4 W power. Introduction of Half Read more…

The solar heat gain constant and shading coefficient are interchangeably used as the property of building façade. However, both properties are different. Let us explain the difference between the solar heat gain coefficient (SHGC) and the Shading Coefficient: Solar Heat Gain Coefficient (SHGC) SHGC of a glass indicates that how Read more…

Solar PV market is predominantly using Mono crystalline and Poly crystalline solar panels. As the name suggest, Mono crystalline cells are made from a single continuous crystal structure. Mono crystalline panels can be identified visually as the cells appear as a single flat colour, generally dark black. The solar cell Read more…

Tier 1 manufacturers are the companies in the quarterly Bloomberg New Energy Finance (BNEF) and is a flat term used by sales companies and manufacturers. “Tier 1 module manufacturers are those which have provided own-brand, own-manufacture products to six different projects, which have been financed non-recourse by six several (non-development) Read more…

While you decide to install a solar power plant at your rooftop, it is important to select right size of solar PV system. Here are 5 key considerations which you should consider while deciding the solar PV system size for your home or in your commercial building as per your Read more…

The Mono PERC solar technology is recognised into activity by many solar manufacturers. PERC stands for Passivated Emitter and Rear Cell. This technology differs in term of solar architecture. However, the electrons are collected in top layer of solar cells. In PERC technology, an extra layer at the rear side Read more…

Solar inverter is the heart of a solar system as it converts DC electricity into AC electricity. Typically apart from PV module, the largest hardware related expenses are done in solar inverters and accordingly it becomes important to select a right inverter for your rooftop solar application. There are number Read more…

A solar still distills water, using the heat of the Sun to evaporate, cool then collects the water. There are many types of solar still, including large scale concentrated solar stills, and condensation traps (better known as moisture traps amongst survivalists). In a solar still, impure water is contained outside the collector, where it is evaporated by sunlight shining through clear Read more…
