Introduction
In February 2026, the conversation around solar energy in Sri Lanka has shifted from “going green” to “financial survival.” With the recent CEB and LECO tariff adjustments, electricity has become one of the most significant monthly overheads for households and businesses alike. At Solartherm, we believe that understanding the numbers is the first step toward energy independence.
The Reality of the 2026 CEB Bill
Following the latest hikes, the “Fixed Charge” and the per-unit rate for consumers exceeding 180 units have reached historic highs. For a typical household consuming 300 units, a monthly bill now often exceeds Rs. 15,000. For those in the higher brackets (over 600 units), bills are surpassing Rs. 30,000.
