Solar returns in Jamaica have a property most investments lack: they compound automatically with every JPS rate increase — your system’s “dividend” is repriced upward each time grid power gets more expensive, while your cost stays fixed at installation day.
How the compounding works
A system saving J$300,000 a year at today’s rates (historically US$0.30–0.40/kWh all-in) saves proportionally more after every tariff adjustment — same panels, same sunshine, larger avoided bill. Over a 25-year panel warranty, even modest rate drift adds seven figures to lifetime savings.
The cost of waiting, quantified
A household with a J$30,000 bill that waits one year pays JPS roughly J$360,000 for power its roof could have produced — most of the way to a starter system (J$522,000 installed). Two years of waiting outspends the system. Delay is the most expensive financing plan available.
Front-loading your return
Right-size from day one (free at btechj.com/solarestimate), design for self-consumption, and stage storage if budget demands — a grid-assisted start at J$522,000 begins the compounding immediately, with batteries joining later.
FAQ
Do returns really rise without doing anything?
Yes — avoided-cost savings track the rate you avoid. Rate rises are your raise.
What is the payback at today’s rates?
Roughly 3–5 years on right-sized BTECH systems.
Best month to start?
The one before the next rate increase — practically, this one: 876-777-5488.
