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.

Under the DBT scheme, the subsidy application process has become much easier. Here's a step-by-step breakdown:

• Visit the National Portal for Rooftop Solar website.
• Download the Sandes app from the website and install it.
• Register as a customer on the Sandes app.
• Once registered, a discom official will visit your home to assess technical feasibility.
• After receiving the No Objection Certificate (NOC) from the official, choose Isha solar as your solar installation company.
• Discuss the project details with us and sign an agreement.
• Upon receiving payment, we will commence the installation process.
• We will then provide a work completion report and apply for a net meter installation on your behalf.
• You will receive a commissioning certificate upon completion.
• Submit your bank account information and upload a copy of a cancelled cheque through the National Portal for Rooftop Solar.
• Once the fund handling agency receives your details, the subsidy will be credited to your bank account within 30 days.

By following these steps, you can smoothly complete the process and enjoy the benefits of solar energy.

If you are planning to install solar for home or housing societies, the solar panel for home price list we’ve curated will greatly help you. Here's the reference about the range of solar panels for home cost without a subsidy in India:

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.

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.

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.

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.

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.

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. Isha Solar Energy 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.

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 4 units of electricity per day.

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.

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, Isha Solar conducts a scientific mapping of the appropriate project size for you.

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.

The Solar Plant life is 25 years. The main components are solar panels and inverters. Solar panels have a warranty of 25 years and inverter warranty ranges from 5-12 years.

A Solar Rooftop module comprises minimal moving parts and hence has very low maintenance cost. IshaSolar Energy provides first 5-year maintenance free of cost to clients ensuring a hassle free experience for all our customers.

Isha solar ensures that no damage to the existing structures takes place during the installation or running of the solar plant. We use a multitude of techniques like non-penetrating structures and waterproofing solutions to ensure your roof’s integrity.

It is a good practice to clean the solar panels 1-2 times a month. It is safer to clean the panels early in the morning or at night when no incident sun rays are present and the power plant is not producing any electricity. You can simply use a clean wet cloth, soft nylon brush or sponge to wipe the surface but ensure the panels are clear of any moisture. Don’t use metal brushes or detergents as these may streak the glass of the panel.

Solar power plants can be installed on almost any type of roofs irrespective of their shape or material type. In cases where the construction material is brittle (Asbestos) or the roof integrity is compromised, Isha Solar Energy provides roof replacement solutions as part of the solar rooftop project.
