The fastest way to know what solar system your Jamaican home needs is the free BTECH calculator at btechj.com/solarestimate — a few questions about your bill and appliances, and it recommends a realistically sized system in about five minutes.
What it asks
Your monthly bill range, household appliances — AC units and sizes, water heating, pumps, freezers, heavy tools — and usage patterns. These are the exact inputs a human engineer would collect first.
What it returns
A load classification and a matched system recommendation: inverter class (6kW–12kW hybrid), panel count (605W modules), and battery guidance — mapped to real packages that start at J$522,000 installed. Because it draws on the same product set our installers fit, the recommendation is buildable from stock, not theoretical.
Why guessing fails
Undersized systems disappoint at night; oversized ones waste six figures. The calculator’s job is to land you inside the right tier before a single dollar moves — refined afterwards by a human (free) if you want the belt-and-braces pass.
