Installed 5.5 kW off-grid solar system at my SLBC batchmate Engineer, Mr Hewage’s Boralesgamuwa residence with 460w/ 06 panels & Amaron Solar Tubular 100A/ 12V, 04 batteries. During the day time total load will run direct from solar system, and during the night time Battery backup will run the load for 03 hours, then reduce monthly electricity bill by 70%.
