FAQ's

PV, short for Photovoltaic, derives its name from the process of converting light ('photo') directly into electricity ('voltaic'). Simply put, a Solar PV system is a power station that generates electricity from sunlight.

A PV system consists of different components, including:

  • Solar Modules (group of solar cells)
  • Charge Controllers (to control the amount of charge going into the inverter)
  • Inverters (to convert the direct current (DC) of a PV system into alternating current (AC) for use in electrical appliances)
  • Batteries (to store any excess energy and use it when the PV system is not generating power) (for off-grid and hybrid systems only)
  • Racking (mounting hardware for the modules) etc.

Such rooftop systems can be installed at the roofs of residential and commercial complex, housing societies, community centers, government organizations, private institutions etc.

Solar PV is a highly proven and reliable technology and have been in use since 1950s. A PV system that is designed, installed, and maintained well will operate for 25 years or even more than 25 years. The Inverters, which are an integral part of a Solar PV system, may need a replacement once in the 25 years lifetime of the system. Moreover, since there are no moving parts (unless you are using tracking devices to move modules tilt with the movement of the Sun), there is practically negligible wear and tear.

Going solar will help you in the following ways:

  • Save Money: Solar power is often cheaper than your grid electricity. There is also no peak time "demand" charge associated with solar electricity. If you own the rooftop system, you will have access to free electricity after a certain time period – i.e. once the initial cost of the system is amortised. [refer (c)].
  • Lock In Your Energy Costs: As fossil fuel stocks deplete, the costs of grid based electricity (generated using fossil fuels) will continue to rise. Going solar allows you to locked-in your energy costs for the lifetime of the system, typically a period of 25 years or more.
  • It Makes Perfect Business Sense: Depending on your electricity consumption and the incentives and/or rebates available in your area, your rooftop solar system could pay back for itself in as little as 4-5 years. Since the systems last for as long as 25-40 years, you will have access to free electricity for many years.
  • Improves Your Business' Public Perception: Solar systems are an emissions free source of electricity generation. Therefore going solar also has huge environmental benefits. This will improve the perception of your business in the eyes of your customers, your employees, the community and even the government. It's great CSR.

Absolutely! Solar is for everyone. Whether you are a residential solar, commercial or industrial consumer, a smart city developer or a public utility service provider, you can use solar in a variety of ways and save big on your electricity bills year after year, for a lifetime.

By using Solar PV power, you also stabilize your existing electricity supply as well as reduce your dependence on more expensive sources of power like Diesel Generators and Inverters. You can save up to 50% on your electricity bill. It reduces carbon footprint, thus is extremely environment friendly.

Under net metering, electricity generated by the Solar rooftop system is first utilized by the consumer to meet their internal/captive requirements. Excess electricity, if any, is exported to the grid. Subsequently, when the consumer imports power from the grid, the exports are adjusted against the imports, lowering the electricity bill.

A net meter (bi-directional meter) records the energy imported from the grid to meet the load and surplus energy exported to the grid after consumption. Both energy import and export are recorded in the net meter. The difference between export and import readings is the actual energy consumed/delivered.

Subsidies are available from multiple channels for setting up Rooftop PV projects.

Subsidy/Support from Central Government through MNRE:
Capital Subsidy at the rate upto 30% of the benchmark cost for general category states (upto 70% of the benchmark cost for special category states i.e., North MNRE PV Rooftop Cell, pvrooftop@gmail.com, Supported by EU, DCI/ASIE/2014/343-602 LOT 1 3/4 Eastern States including Sikkim, Uttarakhand, Himachal Pradesh, Jammu & Kashmir and Lakshadweep, Andaman & Nicobar Islands) is being given in residential, institutional (hospitals, educational institutes, etc.), social sector etc.

Commercial and Industrial sectors will not be eligible for the above mentioned subsidies.

Government Institutions including Public Sector Undertaking (PSU) shall not be eligible for subsidy; instead they will be given achievement-linked incentives/awards.

Subsidy/Support from State Government through State Nodal Agencies (SNAs):
Subsidy support is also available in various states. The percentage of subsidy varies according to the state policies.

Estimating the approximate capacity of the solar PV system you require and can install for your facility should be undertaken keeping in mind your requirements, your constraints, and the amount of sunlight available.

This would depend on various factors such as the shadow-free area available, the orientation of the roof etc.

Simply put, for 1 kw of solar power, you require 100 sq feet area.

For example if your total requirement is of 5 kw power, your total area requirement will be 500 sq feet.

1 kw of solar system produces roughly 5 units of energy with the sun shining for a good 8 hours a day.

Therefore, in case you have a 10kw system, you will generate about 50 units of electricity with which you can power all your electrical needs including refrigerator, ACs, TV and more.

The annual maintenance and recurring costs are almost negligible, since there are no moving parts and the input fuel (sunlight) is free. For optimum performance, the system only requires cleaning of modules and basic preventive and corrective maintenance
