The short answer: Port-au-Prince sits at 18.59° N, 72.31° W — subtropical latitude. This page's 1400–1800 kWh per kWp per year band is a rough latitude-only estimate with unknown source grade, not a local measurement or forecast. For location-specific weather input, the calculator uses five years of hourly NASA POWER data. See the estimate's provenance.

What the calculator does for Port-au-Prince

Type "Port-au-Prince" (or use your exact GPS coordinates) into the estimator and it will:

Worked example: a 10 kWh/day household

This static example uses the unsourced latitude-only yield band above and a fixed 1.5× dark-week margin. Treat the panel range as an illustration, not a forecast or sizing recommendation. The battery column is re-sized by the simulator against your location's darkest week, so its result can differ from this static band:

Every money figure here is in US dollars; the calculator converts to your own currency. Payback depends on your local tariff: at ~$0.33/kWh a 60% cut on this load saves roughly $723/year, which repays landed-DIY component costs (about $1,676) in about 2.3 years. Where power is cheap, payback stretches — the tool shows your personal number from your own rate.

Why simulate instead of estimate?

Latitude bands cannot capture local clouds, roof shade, or orientation. The five-year hourly weather simulation models seasonal conditions and the darkest week, but it is still an estimate rather than a roof survey.

Frequently asked

How much solar do I need in Port-au-Prince?

It depends on your daily kWh use and roof conditions. The static latitude band on this page has unknown source grade and is not a local production forecast. The free calculator estimates production from five years of hourly NASA POWER weather at your coordinates.

Does solar work in Haiti?

Latitude alone cannot predict output at a specific roof. Local weather, shade, orientation, and installation matter; the calculator uses hourly weather data to estimate location-specific sizing.

Is the Port-au-Prince solar calculator free?

Completely. No signup, no email, nothing for sale. You type your city or coordinates, enter your bill or daily usage, and get off-grid tiers, bill-cut scenarios, payback, and a hardware parts list — all computed in your browser.
