Best solar panel angle in Mariel
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
21°collects the most energy over a year: 1629 kWh per kWp.
28°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Mariel produces the most over a year at 21°. The design month for an off-grid system is December: at 28° it makes 4.04 kWh per kWp a day, 5% more than at 21°, and costs 1% of the yearly total. Why steep panels win winter.

Sizing example. To run a 1 kWh-per-day load through June on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 620 Wp of panels at 70°, versus 310 Wp at 21°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.

73rdof 123 places in Cuba for sunshine, shared: 5.32 peak sun hours a day on flat ground.
−1%solar energy a year compared with the average place in Cuba: 1,629 against 1,639 kWh per kWp.
−1 mindaylight on the longest day, compared with Havana: 13 h 33 min against 13 h 34 min.
21°best year-round tilt here; across Cuba it runs from 19° in Puerto Padre to 22° in Consolación del Sur.
Of the 123 places in Cuba, Niquero gets the most sun (5.68 peak sun hours a day) and Remedios and one other place the least (5.17); Mariel ranks joint 73rd. In its darkest month, June, 1 kWp of off-grid panels at 70° makes 1.89 kWh a day here, against 1.85 kWh on average in Cuba. The shortest day lasts 10 h 43 min, +1 min compared with Havana.
