How Big Should a Whole House Solar Power System Jamaica Homeowners Choose?
Once you know your loads, you can translate that into kW and kWh.
Typical system sizes for Jamaican homes
|
House Type |
Typical Solar Size (PV) |
What It Can Cover |
|
Small home (1–2 people) |
3–5 kW |
Lights, fridge, fans, TV, some small appliances |
|
Medium home (3–5 people) |
6–8 kW |
Above + 1 AC, washing machine, some hot water support |
|
Large home / villa |
10–15 kW |
Multiple ACs, laundry, some hot water, maybe pool pump |
If your goal is “solar power for entire house Jamaica” (not just part of it), most homes eventually land in the 10 kW+ range with battery storage.
Designing a Whole House Off Grid Solar System Jamaica Can Rely On
To go from “I have some panels” to a whole house off grid solar system Jamaica can trust, you need three things working together:
-
Enough PV to cover daytime consumption and recharge batteries
-
Enough battery (kWh) to carry you through night and cloudy days
-
A hybrid/off-grid inverter + optional generator to handle peaks & bad weather
Jamaica has around 5.5 hours of effective sun per day, which is excellent for off-grid.

Key design notes for a whole house solar power system Jamaica off-grid plan:
-
Use LiFePO₄ battery where possible for longer life and deeper usable capacity.
-
Use gas stoves and solar water heaters / heat-pump water heaters to shrink the needed PV + battery size.
-
For villas, upgrade pool pumps to inverter/variable speed and run them mainly during midday solar peak.
-
Divide loads into critical (fridge, lights, Wi-Fi, security, 1 bedroom AC) and non-critical (dryer, pool pump, extra ACs) and control them via an energy management system (EMS).
Example: Whole House Solar Power System Jamaica Daily Schedule (Medium Home)
Imagine an 8 kW PV + 50 kWh battery + 10 kW inverter whole house solar power system Jamaica setup:
-
06:00–09:00 – Battery runs lights, fridge, Wi-Fi, 1 bedroom AC on low.
-
10:30–15:00 – Solar peak: washing machine, pool pump, and water heating assistance run while charging battery to 100%.
-
18:00–23:00 – Family time: living room AC, TV, kitchen work (mostly gas cooking), lights. Battery discharges steadily.
-
Cloudy day – If battery State of Charge drops below 25–30%, generator auto-starts for 1–2 hours, topping battery back to ~50–60%.
This is the type of complete home solar package Jamaica households look for.
