FAQ

A: Photovoltaics is conversion of light energy to electrical energy. This uses semiconductors such as silicon in different forms such as mono-crystals, poly crystals, amorphous crystals etc.

The solar radiations incident on the solar panels produce DC electricity. This DC electricity is converted to AC by an inverter. This power is supplied to the load in different form of grid-tied, stand-alone and hybrid, as per requirement.

A: A solar PV system as per requirement, may comprise of Solar PV module, power conversion unit (PCU) includes inverters, VFDs and solar MPPT chargers, battery, AC and DC junction boxes, protection switch gears, wires, energy meters, remote monitoring and data logging systems.
A: 100 sq. feet or 10 sq. meters of shadow free area is required for 1kW of rooftop solar system.
A: In case of industrial shed, solar panels are mounted on high-quality aluminum structures, which can be fixed to the roof sheets. The solar panels can be installed without penetrating the roofor in some cases, penetrating the roof with due precautions being taken to prevent leakage. Installation on RCC roofs does not require any penetration.
A: The grid connected rooftop system can work on net metering basis wherein the beneficiary pays to the utility on net meter reading basis only. Alternatively, two meters can also be installed to measure the export and import of power separately. The mechanism based on gross metering at mutually agreed tariff can also be adopted.
A: Going solar has never been so economical as it is now! The cost of solar PV system depends on a couple of aspects such as type of system, shadow free area available, PV system size, monthly electricity cost, category of tariff, government policies, government incentives etc. You can click here to get a Free quotation.

The payback period is in the range of 3 to 5 years.

A: The time for installation depends on the capacity of the system. A rooftop system can take up to 1 month.
A: Solar PV modules are manufactured in a way to work beyond their 25-year warranty. They have a rugged built with no moving parts and can sustain in worst of the conditions.
A: 80% accelerated depreciation in tax for commercial and industrial establishments.

30% subsidy for residential establishments and non-profit organizations.

A: Solar PV panels are capable of harnessing direct as well as indirect reflected solar radiations. This enables harnessing solar energy even during grey sky. The grey sky affects the generation but to a limited extent depending on the density of clouds. The cloudy sky increases the efficiency of solar PV system as it helps keeping the atmospheric temperature below limits. In fact, rains can be a blessing in disguise for the solar panels as it would rinse the dirt off of the solar panels, enhancing the efficiency even more.
A: We give our clients a set of options from tier 1 and tier 2 manufacturers of solar PV modules and solar inverters and also suggest the best suited option. All the PV modules and inverters are MNRE approved.
A: All different OEMs manufacture solar PV modules and solar inverters to match the same standard certification, which makes them compatible enough to work together to harness maximum solar energy.
A: Yes, there are various types of data monitoring and data logging systems available. The data can be accessed on website & mobile app.
A: Yes, the DG set can be replaced by a hybrid or an off grid solar PV system. With a solar PV system, you can do away with the DG set, its maintenance and the ever increasing cost of Diesel.
A: Inverters and other power conversion units can be installed outdoors. All inverters and solar PCUs are IP 65 complied, completely protected from dust and water jets. But they should be protected, under a shed from continuous ingress of water such as rain.
A: Not necessarily, for grid-tie systems. For off-grid or hybrid systems in case of absence, there has to be parallel wire connectivity to the loads in order to be supported with backup.
A: It is possible to make a backup inverter compatible to work with the solar PV modules to charge the batteries by adding an extra PCU module, solar MPPT chargers.
A: Solar water pumps can be installed for irrigation purposes. Existing water pumps can also be made to work on solar and made energy independent. Solar DC water pump is another good option.
A: Solar water pump systems come with tier 1 company PV modules, a VFD and a water pump as per requirement. If the pump is required to work anytime through 24 hours, then the VFD is replaced by an inverter along with required size of battery.
A: Solar Street lamps can be used for a variety of purposes, lighting the street, lighting outdoor area of a premise, lighting up gardens, lighting up common areas in a colony etc. Now-a-days LED lamps are extensively used in solar lamps due to their high luminance per Watt ratio. They are available in a range of 15 W to 100 W, and selected based on the distance between two lamps. They are highly preferred on account of their stand-alone feature.
A: The Govt. of India has instructed to all Public Sector Banks to encourage home loan/ home improvement loan seekers to install rooftop solar PV plants and include cost of system in their home loan proposals. So far, nine PSBs namely Bank of India, Syndicate Bank, State Bank of India, Dena Bank, Central Bank of India, Punjab National Bank, Allahabad Bank, Indian Bank and Indian Overseas Bank have given instructions to extend loan for Grid Interactive Rooftop Solar PV Plants as home loan/ home improvement loan.
A: Not necessarily. The cost of solar PV modules has fallen drastically in last few decades. Moreover, cost of other components such as copper wires, aluminum structures, PCUs, switch gears and labor is ever increasing hence, the cost of solar PV system are unlikely to fall any further. Thus, you are in fact losing the opportunity to maximize your savings day by day.
