A fixed array in Paysandú produces the most over a year at 28°. The design month for an off-grid system is June: at 58° it makes 3.43 kWh per kWp a day, 14% more than at 28°, and costs 11% of the yearly total. Why steep panels win winter.

Sizing example. To run a 1 kWh-per-day load through December on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 440 Wp of panels at 70°, versus 390 Wp at 28°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.

How Paysandú compares in Uruguay
Against the other 30 places in Uruguay with climate data, for a fixed array at its best angle.
3rdof 31 places in Uruguay for sunshine, shared: 4.83 peak sun hours a day on flat ground.
±0%solar energy a year compared with the average place in Uruguay: 1,592 against 1,584 kWh per kWp.
−14 mindaylight on the longest day, compared with Montevideo: 14 h 17 min against 14 h 30 min.
28°best year-round tilt here; across Uruguay it runs from 26° in Artigas to 29° in Montevideo.
Of the 31 places in Uruguay, Artigas gets the most sun (4.86 peak sun hours a day) and Rocha the least (4.64); Paysandú ranks joint 3rd. In its darkest month, December, 1 kWp of off-grid panels at 70° makes 2.66 kWh a day here, against 2.85 kWh on average in Uruguay. The shortest day lasts 10 h 02 min, +13 min compared with Montevideo.
