Frequently Asked Questions

What are the financial benefits of solar energy ?

When you install a solar energy system on your property, you save money on your electricity bills and protect yourself against rising electricity rates in the future. How much you can save depends on the utility rates and solar policies in your area, but going solar is a smart investment regardless of where you live in India.

What are the environmental benefits of solar energy ?

Solar power, like other renewable energy resources, has many environmental and health benefits. Going solar reduces greenhouse gas emissions, which contribute to climate change, and also results in fewer air pollutants like sulfur dioxide and particulate matter, which can cause health problems.

What is Net Metering ?

Net Metering is billing mechanism for grid connected Home Rooftop Solar Installation where :-
  • 1. The electricity generated by the solar panels is fed into the utility grid.
  • 2. Household draws electricity from the utility grid.

The household pays only for the difference between the energy units it consumes from the grid and the energy units fed into the grid. This is measured by a bi-directional meter called Net Meter. In the case of household generating net excess power during a month or a particular billing period, it earns credit for the excess electricity fed to the grid. This credit is carried forward to the next billing period when the credit is deducted from the total power bill of the consumer. This reduces power bill of the household as it only has to pay for the net electricity it consumes from the utility grid.

How do solar photovoltaic (PV) panels work ?

Solar panels absorb the sun's energy throughout the day and convert it into direct current (DC) electricity. Most homes and businesses run on alternating current (AC) electricity, so the DC electricity is then passed through an inverter to convert it to usable AC electricity. At that point, you either use the electricity in your house or send it back to the electric grid.

Do my solar panels produce power when the sun isn’t shining ?

The amount of power your solar energy system can generate is dependent on sunlight. As a result, your solar panels will produce slightly less energy when the weather is cloudy, and no energy at night. However, because of high electricity costs and financial incentives, solar is a smart decision even if you live in a cloudy city.

What happens if there is snow on solar panels ?

Solar panels convert sunshine into power, so if your panels are covered in snow they can’t produce electricity. Snow generally isn’t heavy enough to cause structural issues with your panels, and since most panels are tilted at an angle the snow will slide off. If snow does accumulate, your panels are easy to clean.

Can I go off grid with solar panels ?

When you install solar panels on your property, you will still be connected to the grid. This allows you to draw from the grid when your system is not producing all of the power that you need, and send power back to the grid when you produce more than you use. It is possible to go off the grid with a solar energy system that includes battery storage, but it will cost significantly more and is unnecessary for the majority of homeowners.

Will I still receive an electric bill if I have solar panels ?

Unless your solar energy system includes battery storage and you are fully off the grid, you will still receive a bill from your utility. However, you can dramatically reduce your bill, or even cut the amount you owe to Rs.0, with a solar panel system that matches your energy use.

How much will solar panel maintenance cost ?

Solar panel systems are made of durable tempered glass and require little to no maintenance for the 25 to 35 years that they will generate power. In most cases, you don’t even need to clean your solar panels regularly. If something does happen, most equipment manufacturers include warranties, although warranty terms depend on the company.

Is my roof suitable for solar panels ?

Southerly-facing roofs with little to no shade and enough space to fit a solar panel system are ideal for installing solar. However, in many cases there are workarounds if your home doesn’t have the ideal solar roof.

Why one should go solar?

There are many financial and environmental benefits of going Solar:

What are the different types of solar PV rooftop system available in the market?

Over the years, people have come up with many innovative uses of Solar technologies. In India, primarily 3 types of system are available:
  • 1. Grid Tied System

    This system works only with the electricity grid without batteries. Although, this system has no power back-up but is much cheaper and has no recurring cost. Government backed subsidies reduce the cost further. This system is ideal for cities where there is little to no power cut.
  • 2. Off Grid System

    This system works without the electricity grid and has power backup options. This is ideal for cities where there is no connection to the grid.
  • 3. Hybrid System

    As the name suggests, it is a combination of Off Grid and Grid Tied system. It works as a Grid Tied system when electricity is available and works as Off Grid in case of power cut. It has batteries to store energy. It is the most expensive of the 3 systems. It is ideal in cities where there are frequent power cuts.

How does a different weather condition impact the output of solar PV system?

Output from Solar PV system is dependent on intensity of light and duration of the day. In rainy and winter seasons, output is slightly lower but still the system works smoothly as sunlight is available most of the time.

What is the periodic maintains required for the system?

Systems are provided with 5 years maintenance. Panels and Inverters have long term warranties in place.
We provide regular checks to ensure that solar panel production is optimal. Cleaning of solar panels to remove dust will ensure a hassle free usage.

Will Solar operate during power cut?

Hybrid and Off Grid systems are designed to work during power cuts. They have batteries to store electricity and provide backup during power cuts. Grid Tied systems don’t provide back up as it needs reference voltage from grid and they have no batteries to store electricity.

Can I try to make fixes or repair to my solar panel system?
