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…
In recent years we have seen that many commercial buildings are coming up as a whole glass buildings. In Indian context buildings with full glass is not desirable as the larger amount of glazing leads to a huge amount of heat gain of overall building. Hence, it becomes important to 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…

Low-e stands for low-emissivity and refers to a special coating that reduces the heat transfer of a window assembly. Low-e coated products that reduce solar heat gain can be produced by adding a metallic coating either while the glass is in a molten state or by applying to the glass Read more…
The sun emits visible solar radiation in the form of light and infrared radiation that cannot be seen, but causes heat. Spectrally selective glass transmits a high proportion of the visible solar radiation, but screens out radiant heat from the sun – significantly reducing the need to cool a building’s Read more…
The SHGC and U-factor ratings are the most important items to verify during inspections. Building professionals should verify that the ratings of the installed windows, doors, and skylights meet or exceed the ratings specified on the plans. It is also important to verify that the same window area has been 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…
