There are a series of important questions that come to mind when talking about sizing a PV system. 1.What is your monthly electrical usage? Your utility bills will show you how many kilowatt-hours of electricity you use on a monthly basis. You can calculate the watt-hours of each appliance you Read more…
SunPower has released a new roof-integrated solar system, called OneRoof. KB Home is the first homebuilder to offer the product in a new-build home community in the San Francisco Bay Area. KB Home is using the solar product in California to meet the state’s mandate that all new homes be equipped Read more…
Small amounts of electricity generated by residential PV systems can be easily fed into the local utility grid. Transformer capacity, appropriate grounding and system protection are obligatory, as otherwise the grid itself would be affected. The situation changes if the solar PV-generated electricity is beyond the limit of what an Read more…

CFA (subsidy) of 30% of the benchmark cost for residential, institutional and social sector will be provided through SECI under this scheme. A total of 122 developer/Installers have been selected forRTS installations across the country. Read more…
Following the Paris Club Agreement, India took up an ambitious plan of adding 175 GW of renewable power. Of this, solar energy (100 GW) comprises a major part of 175 GW target followed by wind (60 GW), biomass (10 GW) and small hydroelectric (5 GW). The target of 100 GW Read more…
MNRE is also promoting off-grid renewable energy systems and solutions especially in the rural and remote areas of the country. The off-grid systems are significant from the perspective of hot water requirements of the residential, commercial and industrial sector, cooking energy needs in the rural areas, lighting needs in remote Read more…
In grid-connected rooftop or small SPV system, the DC power generated from SPV panel is converted to AC power using a power conditioning unit and is fed to the grid either of 33 kV/11 kV three-phase lines or of 440V/220V three/single phase line depending on the local technical and legal Read more…
Solar Rooftop System provides following technical benefits: Utilization of available vacant roof space; Low gestation period; Lower transmission and distribution losses; Improvement in the tail-end grid voltages and reduction of system congestion; Loss mitigation by utilization of distribution network as a source of storage through net metering; Long term energy Read more…
