After installation, charging your home and batteries from solar costs J$0 per kilowatt-hour — the entire cost of solar lives in the upfront system price, which starts at J$522,000 installed in Jamaica. Compare that with buying every kilowatt-hour from JPS at historically US$0.30–0.40 all-in, forever.
The cost structure flip
Grid power is a rental: low entry, endless payments that track world fuel prices. Solar is ownership: one purchase, then decades of production from panels warrantied 25+ years. Most right-sized BTECH systems recover their cost in roughly 3–5 years; everything after is nearly free energy.
What “charging with solar” costs by setup
Daytime-only (no battery): from J$522,000 installed — your appliances run on sunshine while it shines.
Day and night (with lithium storage): from about J$1.14M — panels charge a 10–16kWh battery (J$360,000–J$450,000 as components) that carries the evening.
Charging devices, tools and even EVs: marginal cost zero once capacity exists — the system does not care what it charges.
Sizing the “charger” correctly
Count what you actually run — fridge, fans, pump, AC — and size inverter (6kW–12kW) and battery around it. The free BTECH calculator converts your appliance list into a system recommendation in minutes.
FAQ
How much does one full battery charge cost from solar?
Nothing — the panels have no fuel bill. From JPS, filling a 15kWh battery would cost roughly J$900–J$1,200 at typical all-in rates.
Can solar charge my system on cloudy days?
Yes, at reduced output — sizing includes weather margin for exactly this.
