Solar’s disadvantages in Jamaica are real, finite and priceable — which makes them manageable in a way that JPS’s open-ended rate exposure never is. Here is the complete honest list.
Disadvantage 1: capital upfront
J$522,000+ installed is real money. Fix: payment plans and bank energy loans, tenure matched to the 3–5 year payback so savings carry installments.
Disadvantage 2: storage economics
Blackout immunity costs J$360,000–J$450,000 per lithium unit. Fix: stage it — start grid-assisted, add the battery when budget allows; hybrid inverters are built for exactly this.
Disadvantage 3: weather dependence
Clouds and short winter days trim output. Fix: sizing margin (our quotes model realistic irradiance, not brochure sunshine) plus grid/generator backstop for storm weeks.
Disadvantage 4: roof requirements
Panels need sound, sun-facing roof area. Fix: high-output 605W modules shrink the footprint; ground mounts and structures solve difficult roofs — assessed free.
Disadvantage 5: a cowboy-installer market
The boom attracted pop-ups. Fix: verify premises, stock, own installers and public work — all checkable at BTECH in an afternoon (109 Main Street, Ocho Rios; gallery).
The disadvantage solar does NOT have
Ongoing cost. No fuel, trivial maintenance — after payback the disadvantages are memories while the production continues for warranted decades.
FAQ
What is the dealbreaker case against solar?
Genuinely tiny bills or no roof rights — otherwise it is timing, not viability.
Biggest avoidable mistake?
Buying on lowest quote — the missing 15% (protection, mounting) returns as failures.
