A fixed array in Junín produces the most over a year at 15°. The design month for an off-grid system is February: at 0° it makes 3.58 kWh per kWp a day, 4% more than at 15°, and costs 3% of the yearly total. Why steep panels win winter.
Off-grid solar in Junín at 70°
Daily energy of 1 kWp by month. Bars: panels at 70°. Line: panels at 15° (year-round best).

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 820 Wp of panels at 70°, versus 340 Wp at 15°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.

How Junín compares in Peru
Against the other 135 places in Peru with climate data, for a fixed array at its best angle.
102ndof 136 places in Peru for sunshine: 4.90 peak sun hours a day on flat ground.
−4%solar energy a year compared with the average place in Peru: 1,538 against 1,605 kWh per kWp.
−3 mindaylight on the longest day, compared with Lima: 12 h 47 min against 12 h 50 min.
15°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); Junín ranks 102nd. In its darkest month, December, 1 kWp of off-grid panels at 70° makes 1.44 kWh a day here, against 1.33 kWh on average in Peru. The shortest day lasts 11 h 28 min, +3 min compared with Lima.
