A fixed array in Ayacucho produces the most over a year at 17°. The design month for an off-grid system is February: at 6° it makes 4.14 kWh per kWp a day, 3% more than at 17°, and costs 1% 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 750 Wp of panels at 70°, versus 290 Wp at 17°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.

How Ayacucho compares in Peru
Against the other 135 places in Peru with climate data, for a fixed array at its best angle.
53rdof 136 places in Peru for sunshine, shared: 5.33 peak sun hours a day on flat ground.
+6%solar energy a year compared with the average place in Peru: 1,694 against 1,605 kWh per kWp.
+4 mindaylight on the longest day, compared with Lima: 12 h 54 min against 12 h 50 min.
17°best year-round tilt here; across Peru it runs from 3° in Tumbes to 19° in Arequipa.
Of the 136 places in Peru, Ciudad Satelite and one other place get the most sun (6.60 peak sun hours a day) and La Peca the least (4.16); Ayacucho ranks joint 53rd. In its darkest month, December, 1 kWp of off-grid panels at 70° makes 1.57 kWh a day here, against 1.33 kWh on average in Peru. The shortest day lasts 11 h 21 min, −4 min compared with Lima.
