Our Solar Solutions

One of the crucial steps in adopting solar energy is identifying the right type of solar power system

Solar ON-GRID system

ON-GRID solar system means your system is tied to your local utility's GRID. This is what most residential home will use because you are covered if your solar system under or over-produces in regard to your varying energy needs

Solar OFF-GRID system

OFF-GRID solar system is a system that generates electricity, stores that power in solar batteries and runs independently from the power grid. These system encourage off-the-grid living, a lifestyle centered around energy independence and self-sustainability

Solar Hybrid system

Hybrid solar system is a system that generate clean energy to power your home. A hybrid solar system intelligently switches between using solar power, battery storage and grid power. It allows you to avoid using grid power at peak prices leading to bill savings

Frequently Asked Questions

What is a solar rooftop system?

A solar rooftop system is a combination of many components that convert sunlight into usable electricity.

The components of a rooftop solar include the following -

Solar panels with PV cells
Solar inverter
Solar panel mounting structures
AC and DC cables

AC combiner box
DC combiner box
Earthing cables
MC4 connectors

How does a solar rooftop system work?

A solar rooftop system works on the concept of conversion of sunlight into electricity. The phenomenon is known as the photovoltaic effect.

When sunlight falls on the PV cells in a solar panel, the sunlight is converted into electricity. The generated power is DC current. An AC combiner box is used to convert that DC power into usable AC power.

The generated AC electricity is fed into a bidirectional meter that supplies power to the house. It also exports excess power to the DISCOM (grid) and imports power from the grid if electricity generated by the rooftop solar system is not enough to cover the daily requirement.

Why should I go solar?

If you want to save money from the sun, Solar is the best investment for you.

Solar allows you to save on your monthly electric bills plus it also allows you to save the planet by going green.

Solar energy is a true form of renewable clean energy which leads to zero pollution (air, noise, land) and emits no greenhouse gases mitigating climate change.

Is solar power safe?

Yes, The electricity produced by a solar power system is no different than the electricity you get from your electricity distribution company.

The only difference is the source. Moreover, it is among the safest source of electricity consumption because it is neither hazardous nor does it release any toxic or harmful gases during production.

What do I need to install a rooftop solar system?

All you need to qualify for a solar system is - empty space on your roof and access to your rooftop.

Just fill the project enquiry form on our website and our team will contact you to discuss your requirement.

Once the project is finalized, we will take care of your entire plant design, installation and maintenance.

What are the different types of solar systems?

There are 3 types of Solar systems depending on whether the plant is linked to the power grid or battery systems for storage.

On-grid solar systems use common solar inverters and are connected to the public electricity grid. Any excess solar power that you generate is exported to the electricity grid and one usually get paid a feed-in-tariff or credits for the energy you export. The policy for getting credits for energy exported to the credit is termed as “Net-Metering Policy” and is available currently in most states of India.
Off-grid solar systems are not connected to the electricity grid and therefore requires battery storage. An off-grid solar system must be designed appropriately so that it will generate enough power throughout the year and have enough battery capacity to meet the home’s requirements, even in the depths of winter when there is less sunlight.
Hybrid solar systems combines solar and battery storage in one and are now available in many different forms and configurations. This means being able to store solar energy that is generated during the day and using it at night. When the stored energy is depleted, the grid is there as backup, allowing consumers to have the best of both worlds.

Do solar panels generate electricity even during monsoon and winter?

Yes, Solar panels do produce electricity in cloudy or rainy weather albeit with reduced efficiency.

This fall in production is considered in the unit generation estimates provided for every project.

Does a rooftop solar PV generate power during a power failure?

No, rooftop solar PV does not function or generate electricity during a blackout due to safety reasons.

Since blackouts occur when the electricity grid is damaged.

If a solar inverter was still feeding electricity into a damaged grid it would risk the safety of the people repairing the fault in the network.

Nigaran provides the option of using a Li-ion storage battery with Solar power plants for areas which suffer from frequent power failures.

This battery unit can store the excess electricity produced during the day and acts as a backup for any electricity requirement during night or in the event of a power failure.

How much electricity does a solar plant produce?

The production level of a solar plant depends on multiple factors like radiation levels, amount of sunlight received, plant design and quality of components.

On an average, 1 kW solar plant produces 5 units of electricity per day.

What kind of appliances can I use on solar power?

Solar Power plants are used to power all types of heavy machinery in industrial plants as well as household electrical and electronic appliances.

Since the electricity produced from the plant is fed in sync with your grid/diesel generator, there are no voltage fluctuations irrespective of the number of appliances you use.

How do I decide what size of plant I need?

The size of your Solar plant depends on the following factors

Your electricity consumption pattern
Available shadow free area
Solar irradiation in your area

Once you enlist your interest in a solar project, Nigaran conducts a scientific mapping of the appropriate project size for you.

What is Net Metering?

Net Metering is a system that gives solar energy owners credits for the power that they add to the grid.

When solar panels produce excess power, that power is sent to the grid. And this power can be ‘taken back’ when the solar plants are not functioning – example, during the night.

When a unit of solar energy that has been ‘net metered’, the bi-directional electricity meter will run backwards.

Customers are billed only for the ‘net’ energy use.
