The Smart Investment

Why On-Grid Solar is Sri Lanka's Best Investment in 2024

With electricity tariffs rising every year and net metering credits rolling over monthly, there has never been a better time to go solar.

Financial Returns

Your Best Performing Investment This Decade

On-grid solar is the only home improvement that pays you back. With net metering, every unit of excess electricity your panels export earns you a credit on your utility bill — meaning you literally sell electricity back to the grid.

Typical household saves Rs. 20,000–60,000 per month

Net metering credits carry forward month-to-month

System cost deductible as a business expense

Protected from rising electricity tariffs for 25+ years

Complete Advantage

Every Reason to Make the Switch

Eliminate Electricity Bills

A correctly sized system can offset 80–100% of your consumption, effectively erasing your monthly electricity expense.

Zero Carbon Footprint

Every kilowatt-hour of solar energy prevents approximately 0.75 kg of CO2 from entering the atmosphere versus fossil fuel generation.

Increase Property Value

Properties with solar systems command a 4–8% premium in market value compared to equivalent non-solar properties in Sri Lanka.

Energy Independence

Reduce dependence on an ageing national grid increasingly stressed by demand. Hybrid upgrades provide full backup capability.

Inflation Protection

Electricity tariffs have risen significantly over 2022–2024. Lock in free energy for 25 years and hedge against future price increases.

National Energy Security

Sri Lanka imports expensive diesel and coal to generate power. Every solar system you install reduces the national energy import bill.

CEB Approved Program

How It Works

Net Metering: Getting Paid for Your Excess Solar

Sri Lanka's CEB and LECO both operate net metering programs that allow on-grid solar customers to export surplus electricity to the national grid and receive bill credits in return.

Common Questions

Frequently Asked Questions

How long do solar panels last in Sri Lanka?

Tier-1 solar panels are warranted for 25 years and typically last 30–35 years. JinkoSolar and Trina panels we install come with a 25-year linear power output warranty guaranteeing at least 80% of initial power at year 25.

Will my panels work during cloudy or rainy days?

Yes. Solar panels generate electricity from ambient diffused light, not just direct sunlight. On overcast days in Sri Lanka, you'll typically generate 25–40% of your peak capacity — still meaningful production. Sri Lanka's annual peak sun hours remain excellent even factoring in cloud cover.

What size system do I need?

System size depends on your roof area, budget, and monthly energy consumption. As a rough guide, a 5kW system costs approximately Rs. 1.2–1.6 million and offsets around Rs. 25,000–40,000 of monthly electricity. Our engineers will design an optimally sized system for your specific situation — free of charge.

What happens during a power outage?

Standard on-grid systems shut down automatically during outages — this is a grid safety requirement to prevent back-feeding while engineers work on lines. For backup power, we offer hybrid system upgrades with lithium battery storage. These keep your home powered even when the grid is down.

Do I need to clean or maintain the panels?

Minimal maintenance is required. We recommend hosing down panels every 3–6 months to remove dust and bird droppings. We also offer annual technical inspection plans that include panel cleaning, torque checks, inverter firmware updates, and full system performance reporting.

What warranty comes with my SolarGrid system?

You receive multiple layered warranties: 25-year panel power warranty from the manufacturer, 10-year inverter product warranty from Huawei or SMA, a 10-year mounting system warranty, and a 5-year workmanship warranty from SolarGrid Lanka on the installation itself.
