Households in our customer base report ECG bill drops of 80-95% after installing a properly sized system. The mechanics behind that number are simpler than they sound.
Once your major loads — fridge, fans, TV, lights — run on solar and battery instead of the grid, your ECG bill shrinks to whatever's left on the circuit, often just a few minor appliances not yet moved over.
An undersized system only covers part of your load, capping your savings well below that 80-95% range. This is exactly why our free survey focuses on your real usage before recommending a package.
