Each column is one day of 2026. Bright: sun above the horizon; soft: civil twilight; line: solar noon. Steps are daylight saving time changes.
Best solar panel angle in Kobayashi
Fixed array facing south (azimuth 180°). Energy per kWp from NASA POWER monthly climate, including clouds, temperature and snow reflection.
29°collects the most energy over a year: 1299 kWh per kWp.
34°gives the most in the darkest month — the one an off-grid system is sized for.

A fixed array in Kobayashi produces the most over a year at 29°. The design month for an off-grid system is December: at 34° it makes 2.98 kWh per kWp a day, 4% more than at 29°, and costs 0% of the yearly total. Why steep panels win winter.

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 630 Wp of panels at 70°, versus 410 Wp at 29°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.

How Kobayashi compares in Japan
Against the other 1,215 places in Japan with climate data, for a fixed array at its best angle.
111thof 1,216 places in Japan for sunshine, shared: 3.96 peak sun hours a day on flat ground.
+1%solar energy a year compared with the average place in Japan: 1,299 against 1,284 kWh per kWp.
−20 mindaylight on the longest day, compared with Tokyo: 14 h 15 min against 14 h 35 min.
29°best year-round tilt here; across Japan it runs from 17° in Miyakojima to 41° in Kushiro.
Of the 1,216 places in Japan, Miyakojima gets the most sun (4.34 peak sun hours a day) and Wakkanai and one other place the least (3.17); Kobayashi ranks joint 111th. In its darkest month, June, 1 kWp of off-grid panels at 70° makes 1.87 kWh a day here, against 2.14 kWh on average in Japan. The shortest day lasts 10 h 03 min, +19 min compared with Tokyo.
