About 15kW Solar System

A 15kW solar system is a complete solar setup with solar panels, solar inverter, solar batteries, and other solar components. These solar panels are installed on the roof or ground near your premises to generate electricity by absorbing sunlight. A 15kW solar system produces 60 units/day and 1800 units/month on average that is more than sufficient for running heavy loads.

Price List of 15kW Solar System

The price of a 15kW solar system is determined by its type or category. There are three types of 15kW solar system and the price of any solar system including the 15kW solar system is measured in terms of solar price per watt

In short, the price of a 15kW solar system started from Rs.50 per watt and it goes upto Rs.80 per watt, depending on the type of solar system.

Solar SystemSelling PricePrice/Watt
On-Grid Solar  SystemRs.7,50,000Rs.50
Off-Grid Solar  SystemRs.10,05,000Rs.67
Hybrid Solar  SystemRs.12,00,000Rs.80

(Inclusive of all taxes) Prices, promotions and availability may vary by Brand, Store and Location, check our Online Solar Shop or Amazon Store for latest price and stock availability. Prices are exclusive of Govt. Subsidy, as the subsidy on solar systems depends on your eligibility and types of solar system.

Types of 15kW Solar System

A 15kW solar system is available in three different types. All these solar systems are different from each other in terms of their component type, functionality, and how closely they are linked to the traditional utility grid.

Each type of 15kW solar system has its unique strengths that determine how well they will fit your needs. So let’s take a look at these various types of 15kW solar systems.

On-Grid Solar System – Saving + Grid Export

Off-Grid Solar System – Saving + Backup

Hybrid Solar System – On-grid + Off-grid

On-Grid 15kW Solar System

An on-grid 15kW solar system will work with government electricity. Solar panels and on-grid solar inverters are the major components of this system. Solar panels generate DC (direct current) electricity during the day by observing the sunlight, and the solar inverter converts the DC to AC for use in homes. 

This solar system will run your connected load from solar power on first priority and by utility grid on second priority. An on-grid solar system can’t provide you power backups since it doesn’t have solar batteries. But this solar system does support net-metering. By using this net-metering feature, you can export extra or unconsumed electricity generated by solar panels to the government grid.

Off-Grid 15kW Solar System

In an off-grid 15kW solar system there are two ways to run your electrical load, first is solar power and second is batteries. Solar batteries are such a component that you do not get in an on-grid solar system but are definitely available in an off grid system.

Solar panels generate DC electricity by absorbing sunlight. This DC electricity then passes through an off-grid solar inverter that converts it into AC electricity. If your solar panels generate more electricity than you consume, you can store the excess energy in the solar battery. You can use this stored electricity later in the nights or during a blackout.

Hybrid 15kW Solar System

A hybrid solar system combines both the functionalities of on-grid and off-grid solar systems. In a hybrid 15kW solar system, there is net-metering as well as solar batteries. When your solar panels produce more electricity than you consume during the day, you can store the excess in a solar battery. When the batteries are fully charged, the excess power will be automatically exported to the grid.

This system has three power options to run your connected load i.e. solar power, utility grid, and battery backup. First of all, your load will be powered by the solar system, followed by solar batteries, and then finally by the utility grid. A 15kW solar system can be customized as per your requirements.

Subsidy On Solar System

A lot of people know the benefits of installing a solar system and also want to install it. But they are unable to do so due to the high initial investment. Therefore, the central government has started the MNRE subsidy on solar throughout India, so that more and more people can get the solar system installed at low prices.

The subsidy rates are mentioned below:

 

Please note: 

  • If you install a solar system with a capacity greater than 10kW, you will not be eligible for a solar subsidy.
  • These subsidy rates may vary according to your state solar policy and your location.
