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
• Solar inverter
• Solar panel galvanized from mounting structures with square foundation
• (AC and DC cables) & Earthing Cable
• AC combiner box (ACDB)
• DC combiner box (DCDB)
• MC4 connectors
• Earthing with chemical bag & Lightning arrestor
• Battery if applicable

• 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. Solar Inverter 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.

If you want to save money from the sun, Solar is the best investment for you. Solar allows you to reduce 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 shadow free south facing 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 finalised, we will take care of your entire plant design, installation and maintenance with subsidy disbursed to Bank Loan.

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. Sun gives two things Heat & Light. Solar convert light into electricity.

No, rooftop solar PV does not function or generate electricity during a blackout due to safety reasons under the UPERC. If a solar inverter was still feeding electricity into grid under shut down as maintenance break it would risk the safety of the people repairing the fault in the network. 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 4-5 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 south facing area
Solar irradiation in your area
Once you enlist your interest in a solar project, Exajoule 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.

Solar panels allow you to lock in your electricity rates for more than 25 years. They will assure you a 25 to 30-year manufacturing warranty with almost no maintenance with a solar plant installed. The value of your property increases while also helping the environment. Even some districts give 10-15% rebate on house tax & water tax.

You may require 70-80 square feet area as little as 200 square feet (for small homes) to as much as 1000 square feet (for larger homes). However, this is not absolute and may vary depending on certain factors such as shadow-free area, the slope of the roof, electricity usage, and so on.

Yes, your solar plant can meet your entire energy needs, but you will need a battery backup to store energy when the sun is not shining. Solar panels only produce electricity during sunny hours, and the excess energy can be stored in a battery storage system allowing you to go completely off-grid.

The average monthly power consumption for a household in India is 250kWh. A 1kW solar system can produce approximately 4-5 units per day, for a total of 1500 units per year. Other factors that influence electricity generation are seasonal change, shadow-free areas, and so on. Our solar experts assist each client in determining the exact amount of electricity that their solar plant can yield.

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 8-10 years.

Has very low maintenance cost. Exajoule provides first 5-year maintenance free of cost to clients ensuring a hassle free experience for all our customers.

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, Exajouleprovides roof replacement solutions as part of the solar rooftop project.

The cost of a solar plant depends on its size, configuration and degree of supporting structures required. We provide you multiple options to choose from, designed specifically to meet your requirements.

At present, the Uttar Pradesh state government provides an additional solar subsidy of ₹15,000 per kw (max ₹30,000) when you install a rooftop solar system, bringing the total maximum subsidy amount to ₹1,08,000.

In a Capex model, the entire investment comes from the power consumer. The consumer hires a solar EPC company who provides turnkey installation of the entire solar power system and hands over assets to consumers. EPC also does annual operation and maintenance (O&M) of plant. In the OPEX model, an investor or project developer (sometimes called Renewable Energy Service Company –RESCO) invests the CAPEX and the consumer pays for the energy consumed. Both consumer and developer sign a long-term power purchase agreement (PPA) for an agreed tenure & tariff.

Exajouleprovides lucrative EMI options while also facilitating collateral free loan facilities provided by various banking institutions for solar projects.

For Residential product all the Govt. PSU bank provide (80-90)% Loan only on basic KYC papers on small interest rate of (6-8)%.
