Given the basic requirements, while planning any type of Solar PV System, the off-grid system differs in design in regard to certain additional components.  Dry and ventilated storage place for batteries, if possible protect against low temp (optimal around 20°C) Thermal systems Additional roof statics approx 50kg for 1 installed collector (40kg collector, Read more…
In the case of PV On-Grid systems, the system sizing depends on profitability, the energy price or feed-in tariff, available mounting area and approved or connectable PV power. Factors affecting design The most important requirement is the roof orientation Optimal inclination angle between 30 – 45° Transmission possibility of a Read more…
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…
There are are a few basic factors to consider when designing any kind of system. Energy requirements2. Peak Sun Hours3. Site Location Evaluation4. Battery bank5. No. of Solar Panels Off-grid systems are designed to work alone and are sized so that they work during the worst conditions of the year, Read more…
The off-Grid system relies heavily on better-abled storage systems. Battery: Stores energy by chemical reactions. Most stand-alone PV systems use lead-acid batteries. Flooded lead-acid battery: A battery that has a liquid electrolyte (fluid) and uses chemical reactions between lead and acid to store energy. Sealed valve regulated flooded lead-acid battery: Read more…
PV module: Turns light into electricity. A group of solar cells in a sealed unit. Grid-tied inverter: An inverter that reads the voltage of the grid and produces as much power and current as it can, regardless of loads. For example, a 5kW inverter can only put out 5kW. Grid-tied 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…
SECI has undertaken competitive bidding at a national level for 500 MWp grid-connected rooftop projects. 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…
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…
