Hanover solar guide

A compact parish with a fairly tight solar range.

Hanover does not show the dramatic internal variation seen in Jamaica’s mountain parishes, but coastal exposure and the difference between Lucea, Green Island and inland hills still matter on a real roof.

Try a system size

What would that mean on a roof?

These figures estimate electricity from the panels, not money saved. A kWh is one unit of electricity on your bill; kW describes the panel system’s rated size. Your savings depend on when you use that electricity, whether you store it in a battery and whether you send any to JPS Jamaica.

The parish is not one number

The northwest is strongest. Most inland cells stay close to average.

The map is strongest along parts of the northwestern coast and becomes more moderate toward the interior and eastern side. The middle half of mapped locations sits within a relatively narrow band.

That makes a roof survey especially important: shade and roof direction can easily outweigh the geographic variation within Hanover.

Month by month

How does solar output change through the year?

March is strongest in the long-term model. June produces about 83% of that output, so the annual figure should not be treated as twelve identical months.

Before asking for quotes

Questions worth asking in Hanover.

Is the property exposed to salt spray?Homes around Lucea, Green Island and the coast need compatible metals, suitable enclosures and manufacturer warranty terms that acknowledge salt exposure.
Can trees shade a small roof area?Mature vegetation can make a few affected modules control the output of a larger string. Ask how the electrical layout handles partial shade.
How is the roof structure verified?The installer should locate sound framing or confirm the concrete structure before choosing fastener spacing and waterproofing details.
Who returns for service?Check response arrangements, monitoring access and replacement-part availability rather than relying only on an islandwide-sales claim.

Use the Jamaica panel and roof guide to test the mounting and equipment answers in a quotation.

Generation is not the bill

A 5 kW system making 658 kWh a month will not automatically erase the same-sized bill.

Timing decides value

Solar used in the home avoids the retail cost of a JPS Jamaica unit. Surplus sent through net billing receives a much lower export credit.

A battery moves energy

A battery can carry daytime generation into evening use and provide outage cover, but it does not make the panels generate more.

Your roof changes the result

Shade, direction, heat, dirt, cable losses and equipment choices move a real installation away from the parish benchmark. Use the panel guide to test those roof assumptions.

How we calculated this

Where do these estimates come from?

We use long-term sunshine data to estimate panel output across the parish. These are planning averages, not a forecast for your roof. Shade, roof direction and equipment can change the result.

See the data, calculation and source assumptions

We selected the 564 Global Solar Atlas PVOUT grid cells whose centres fall inside the Hanover parish boundary, then calculated the annual mean, central 50% range and monthly means.

The source models a free-standing crystalline-silicon system at optimum fixed tilt. It is useful for parish comparison and early planning, not a guarantee for a particular roof.
