Best solar panel angle in Piura
Fixed array facing north (azimuth 0°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
5°collects the most energy over a year: 1634 kWh per kWp.
11°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Piura produces the most over a year at 5°. The design month for an off-grid system is June: at 11° it makes 4.10 kWh per kWp a day, 4% more than at 5°, and costs 0% of the yearly total. Why steep panels win winter.
Off-grid solar in Piura at 70°
Daily energy of 1 kWp by month. Bars: panels at 70°. Line: panels at 5° (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 1,190 Wp of panels at 70°, versus 300 Wp at 5°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.

How Piura compares in Peru
Against the other 135 places in Peru with climate data, for a fixed array at its best angle.
31stof 136 places in Peru for sunshine, shared: 5.56 peak sun hours a day on flat ground.
+2%solar energy a year compared with the average place in Peru: 1,634 against 1,605 kWh per kWp.
−25 mindaylight on the longest day, compared with Lima: 12 h 26 min against 12 h 50 min.
5°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); Piura ranks joint 31st. In its darkest month, December, 1 kWp of off-grid panels at 70° makes 1.00 kWh a day here, against 1.33 kWh on average in Peru. The shortest day lasts 11 h 49 min, +24 min compared with Lima.
