Saving and Earning with Solar Power

The new solar tariff for rooftop Solar power systems in Sri Lanka is Rs. 37 per kWh for systems with capacities up to 500 kW and Rs. 34.50 per kWh for systems with capacities greater than 500 kW. This tariff applies to new customers coming under the “Net Accounting”, “Net Plus” and “Net Plus Plus” schemes. Once the Power Purchase Agreement (PPA) is signed, the relevant tariff will remain unchanged for the next 20 years.

  1. On-Grid Options

On-grid solar power systems are connected to the national grid; they generate electricity that is fed back into the grid. When you generate more electricity than you use, you can sell it back to the grid. Conversely, when you use more electricity than you generate, you buy it from the grid.

“Earn from Solar” is a program that enables you to earn money by generating electricity from your solar panels. The program compensates you for the electricity you produce, and you can also sell any excess electricity back to the grid.

1.1 Net Metering 

Net metering is a billing system that enables you to sell the electricity generated by your solar panels back to the grid. The electricity sold back is credited to your account, and you are only charged for the electricity you use from the grid.

1.2 Net Accounting 

This billing system, similar to net metering, provides a discount on your electricity bill instead of receiving credits for the electricity you sell back to the grid.

1.3 Net Plus

This billing system enables you to sell all the electricity you generate from your solar panels back to the grid, and you incur no charges for the electricity you use from the grid.

If you’re solely looking to save money through solar, then you can opt for:

  1. Off-Grid Options
