Net metering is a core reason solar has gained traction in Sri Lanka – but for many, the concept can be confusing. In this article, we’ll break down what net metering is, how it works in Sri Lanka, and how it benefits homeowners and businesses alike.
What is Net Metering?
Net metering allows solar system owners to connect to the national grid (CEB or LECO) and export excess solar energy. The exported energy is deducted from the energy imported from the grid, resulting in a “net” bill.
How Net Metering Works (with a Simple Example):
Let’s say your solar system generates 500 kWh in a month:
- You consume 400 kWh and export 100 kWh.
- Your electricity bill is calculated only for the “net” 300 kWh consumed from the grid.
- Excess credits (if any) can be carried forward up to 10 years.
The 3 Schemes Explained: Net Metering, Net Accounting & Net Plus
Net Metering:
- Export unused power
- Credits reduce future bills
- No payment for surplus energy — just credit roll-over
Net Accounting:
- You buy and sell electricity separately
- If you export more than you import, you receive a payment at a predetermined rate
Net Plus:
- All energy produced is sold to the grid
- Energy for consumption is purchased separately
- Suitable for businesses producing energy primarily for sale
Who Can Apply for Net Metering in Sri Lanka?
Eligibility is subject to CEB/LECO approval and technical feasibility.
Residential Homeowners
Commercial & Industrial Entities
Government Institutions
Benefits of Net Metering in Sri Lanka
- Reduced energy bills
- Lower payback period on solar investment
- Encourages energy independence
- Supportive of national energy policy
- Allows for grid interaction during night or cloudy days
Common Misconceptions about Net Metering:
“I won’t have power at night.”
False. You will always have access to the grid and can import power when needed.
“The process is too complex.”
CEB and LECO have streamlined processes. Plus, Hayleys Solar manages all documentation for you.
“What if I export more than I consume?”
No worries. Under net metering, excess credits carry forward. Under net accounting, you receive payment.
Frequently Asked Questions
Unless your system has battery backup or a hybrid configuration, solar inverters shut down for safety reasons.
Yes, subject to approval and system reconfiguration.
Net metering empowers Sri Lankans to reduce their energy costs while supporting the national grid. Whether you’re looking to save money or embrace a greener lifestyle, understanding your options is key.
