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…
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…

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…
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…
Question 1: How much does a 100kW commercial solar PV system cost? Answer: A 100kW rooftop system mainly comprised of different components made up of solar PV panels, solar inverter, ACDB, DCDB and many more. These can cost anywhere between INR 40,00,000 to INR 50,00,000 and will depend on the brands you select for Read more…
U-value Thermal transmittance, also known as U-value, is the rate of transfer of heat energy through a structure, divided by the difference in temperature across that structure. The units of measurement are W/m²K. The better-insulated a structure or material is, the lower the U-value will be. Thermal transmittance takes heat Read more…
