First, sunlight hits a solar panel on the roof. The panels convert the energy to DC current, which flows to an inverter. The inverter converts the electricity from DC to AC, which you can then use to power your home.

A PV system is made up of different components. These include-

  1. PV modules (groups of PV cells), which are commonly called PV panels
  2. an inverter for a utility-grid-connected system;
  3. wiring;
  4. electrical & lightning protection devices and
  5. mounting hardware or a framework.

A PV system that is designed, installed, and maintained well will operate for more than 25 years. The basic PV module (interconnected, enclosed panel of PV cells) has no moving parts and can last more than 30 years. The best way to ensure and extend the life and effectiveness of your PV system is by having it installed and maintained properly.

PV can be used to power your entire home's electrical systems, including lights, cooling systems, and appliances. PV systems today can be blended easily with your existing electrical setup. You need roof /ground space where direct sunlight is available throughout the day. Use FUNSOLAR Calculator to know your solar system size and space required to install it.

You don’t need any batteries if you don’t have any power cut. As your solar system is directly connected to the grid (Grid-Connected System), your home appliances directly draw power from the solar system when sunlight is available and draw power from the Grid whenever solar isn’t available i.e. at night and during monsoon.

If your appliances use less power than the power generated by your Solar system, you can export the same energy to the Grid and get credits for those units. These credited units will be set-off against other units which are consumed directly from the grid. This whole process is termed as “Net Metering” and is available with majority utility providers across the country.

Net metering allows customers who generate their own electricity from solar power to feed electricity they do not use back into the grid.
It is a billing mechanism that credits solar energy system owners for the electricity they add to the grid. For example, if a residential customer has a PV system on the home's rooftop, it may generate more electricity than the home uses during daylight hours. If the home is net-metered, the smart electricity meter, also called as Import-Export meter provides a credit against what electricity is consumed at night or other periods where the home's electricity use exceeds the system's output. Customers are only billed for their "net" energy use.

PV systems can be easily setup for any Commercial / Industrial unit where there’s roof/ground space available. Solar PV Systems work efficiently irrespective of the load type and rating.
Ex. Suppose your Solar System size is 40KW and the machines (load) in your facility are collectively consuming 60KW, then 40KW will be drawn from solar system and balance 20kW from the grid.

The size of solar system you need depends on several factors such as how much electricity you use, the size of your roof, and how much you're willing to invest. Our Basic and Advanced Calculator helps you understand all these parameters along with various financing options and to calculate this for you, we just need your average monthly bill amount.

All you need to keep your system generating power is to clean the solar panels every week.
We also provide AMC where there are timely check-ups which ensure electrical and mechanical stability of the system. AMC can be purchased along with the system.

Every Solar System installed by us can be remotely monitored online in realtime. There must be a working internet connection at the installation site. Also it saves past data so you can compare results and optimise cleaning and maintenance of the system.

Payback period depends on your electricity tariff and your mode of purchase.
Ex. For a residential/commercial consumer in Mumbai who purchases a Solar System at his own money, payback can be in less than 4 years.

Outright purchase is the simplest form of owning a solar system. You pay once for the system and get free electricity for next 25 years. Your fixed charges in the bill will still be payable to your Discom.
Individuals/Companies having eligible Cibil Score / Credit Rating can opt for our easy EMI option.
Established Commercial/Industrial Units requiring solar system size greater than 200kW can go for PPA model where they only pay for the Solar Units Generated at a discounted price from their existing tariff. This model is Subject to the Company’s Credit Rating.

Bidding System is the most competitive form of getting a solar system installed from Country’s leading developers.
We at Funsolar, create a customised tender for your requirement and publish it on our unique tendering portal.
This tender once approved, is visible to Selected Developers.
After approval and security deposit from Tenderer and the Developers, we go for “Reverse Bidding” which is a realtime bidding system.
Selected Developers across the country bid for your system and the Lowest Bidder wins the Bid.
Funsolar helps you throughout the process from Creating the tender till generation of Solar Power.
