☀️ ⚡New Rooftop Solar Tariffs in Sri Lanka 🇱🇰 Announced

⭕ Rates have been reduced from the previous top rate of LKR 27.06/kWh.
📊 New Rates (per kWh)
▫️ 0–5 kW: LKR 20.90
▫️ 5–20 kW: LKR 19.61
▫️ 20–100 kW: LKR 17.46
▫️ 100–500 kW: LKR 15.49
▫️ 500 kW–1 MW: LKR 15.07
▫️ 1 MW+: LKR 14.46
⭕ Applies to new rooftop Solar PV systems for clearance requests submitted after June 16, 2025.
⭕ Tariff is locked in for 20 years once the agreement is signed.
⭕ From a solar-industry perspective, the newly reduced rates will be seen as detrimental to the industry, potentially discouraging investment and slowing the growth of renewable energy projects.
⭕ The reality is that the current solar tariff structure is based only on capital and investment costs, while actual average daytime generation costs are not factored in. This results in tariffs that remain well above the real cost of generating daytime power, undermining efforts to reduce overall electricity costs. If affordability is the government’s goal, solar tariffs should be set below the estimated 20-year average daytime generation cost.
⭕ Unlike in the past, Sri Lanka’s grid today has less need for intermittent sources like rooftop solar. Without integrated storage, solar creates imbalances and burdens the grid. The government should shift focus and promote battery-backed solar systems, which support grid stability and reduce reliance on fossil fuels during peak hours.
