Expert Solar Installation and Maintenance Services with Comprehensive Warranty and Insurance Coverage

We have a team of skilled technicians and qualified engineers who provide consultation and installation services under their supervision. Our solar systems come with a 10-year warranty, along with the relevant manufacturer warranties as per the manufacturer guidelines. We also offer an insurance policy for the entire solar system, including the first-year subscription for free. Additionally, we provide free preventive maintenance services for the first year.

On-grid Solar System

On-grid solar system (grid tie or connected solar system) is the most budget-friendly solution of all the above there. Our specialist will design the solar system according to your electricity consumption to zero your electricity bill. Not only that but also if the system is generating more power than is being consumed, extra power will be fed into the main electricity grid. And you will pay by CEB/LECO for the units that are provided to the grid or units will be carried forward for further use within 10 years.

You can supply to the grid in three ways.

  • NET ACCOUNTING – Under this, the excess electricity sent to the Grid will be paid as per the given table. If consumed more electricity than the production, consumers will pay for it according to the normal electricity tariff.
  • NET METERING – the excess electricity sent to the Grid will be paid as per the given CEB/LECO rates. If consumed more electricity than the production, the consumer will pay for it according to the normal electricity tariff.
  • NET PLUS – Generated electricity will be purchased by the CEB/LECO. Consumed electricity costs should be paid to CEB/LECO under normal electricity tariff. CEB/LECO will pay for the exported excess electricity according to the CEB/LECO rates from the date of signing the contract.

Off-grid Solar System

Off-grid solar systems are an independent and sustainable electricity-generating solution. They consist of solar panels, a charge controller, batteries, and an inverter. These systems provide reliable and sustainable electricity, even in remote areas or where access to the grid is limited. They use an integrated battery module to ensure 24×7 availability of power, but users must be prepared to manually switch between the solar system and the grid when needed for high-power tasks using a manual changeover switch.

  • Off-grid solar systems are designed to operate independently of the main power grid.
  • They consist of solar panels, a charge controller, batteries, and an inverter.
  • Solar panels convert sunlight into electricity during the day.
  • The charge controller regulates the flow of electricity between the solar panels and the batteries.
  • Batteries store the electricity for use at night or during periods of low sunlight.
  • The inverter converts the DC electricity stored in the batteries into AC electricity.
  • Off-grid solar systems provide reliable and sustainable electricity in remote areas or where access to the grid is limited.
  • Integrated battery module ensures 24×7 availability of power.
  • Manual changeover switch is used to switch between the solar system and the grid when needed for high-power tasks.

Hybrid Solar System

Hybrid solar systems combine the features of both on-grid and off-grid solar systems. They are connected to the public utility grid and also have battery storage for backup power. These systems provide the benefits of both on-grid and off-grid solar systems. The battery storage system can be used to store excess solar energy generated during the day or to provide power during power outages, ensuring uninterrupted power supply even during emergencies. The battery storage system also allows hybrid solar systems to operate independently of the grid during periods of high electricity demand or when grid power is unavailable. This makes them an excellent choice for locations with unreliable power supply or frequent power outages. Overall, hybrid solar systems provide a flexible and reliable solution for generating electricity from the sun. With the added benefit of battery storage, they ensure 24×7 availability of electricity, making them an increasingly popular choice for homes and businesses alike.
