Best solar panel angle in Golwayn
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
8°collects the most energy over a year: 1863 kWh per kWp.
0°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Golwayn produces the most over a year at 8°. The design month for an off-grid system is July: at 0° it makes 4.54 kWh per kWp a day, 5% more than at 8°, and costs 1% of the yearly total. Why steep panels win winter.
Off-grid solar in Golwayn at 70°
Daily energy of 1 kWp by month. Bars: panels at 70°. Line: panels at 8° (year-round best).

Sizing example. To run a 1 kWh-per-day load through June on LiFePO4 batteries (charge controller, battery and inverter losses included) you need about 1,080 Wp of panels at 70°, versus 270 Wp at 8°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.
