Best solar panel angle in Seydi
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
33°collects the most energy over a year: 1709 kWh per kWp.
63°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Seydi produces the most over a year at 33°. The design month for an off-grid system is December: at 63° it makes 3.15 kWh per kWp a day, 14% more than at 33°, 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 380 Wp of panels at 70°, versus 430 Wp at 33°. The steep array is 12% smaller for the same winter. Size your own system.

How Seydi compares in Turkmenistan
Against the other 35 places in Turkmenistan with climate data, for a fixed array at its best angle.
11thof 36 places in Turkmenistan for sunshine, shared: 5.01 peak sun hours a day on flat ground.
+2%solar energy a year compared with the average place in Turkmenistan: 1,709 against 1,670 kWh per kWp.
+10 mindaylight on the longest day, compared with Ashgabat: 14 h 58 min against 14 h 48 min.
33°best year-round tilt here; across Turkmenistan it runs from 30° in Sarahs to 36° in Daşoguz.
Of the 36 places in Turkmenistan, Sarahs gets the most sun (5.20 peak sun hours a day) and Türkmenbaşy the least (4.48); Seydi ranks joint 11th. In its darkest month, December, 1 kWp of off-grid panels at 70° makes 3.13 kWh a day here, against 3.16 kWh on average in Turkmenistan. The shortest day lasts 9 h 23 min, −9 min compared with Ashgabat.
