A fixed array in Takeo produces the most over a year at 28°. The design month for an off-grid system is December: at 55° it makes 2.58 kWh per kWp a day, 10% more than at 28°, and costs 9% 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 570 Wp of panels at 70°, versus 510 Wp at 28°. Here the lower tilt is the better winter choice — the sun stays high enough. Size your own system.

How Takeo compares in Japan

Against the other 1,215 places in Japan with climate data, for a fixed array at its best angle.

450thof 1,216 places in Japan for sunshine, shared: 3.85 peak sun hours a day on flat ground.

−2%solar energy a year compared with the average place in Japan: 1,254 against 1,284 kWh per kWp.

−14 mindaylight on the longest day, compared with Tokyo: 14 h 21 min against 14 h 35 min.

28°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); Takeo ranks joint 450th. In its darkest month, June, 1 kWp of off-grid panels at 70° makes 2.08 kWh a day here, against 2.14 kWh on average in Japan. The shortest day lasts 9 h 57 min, +13 min compared with Tokyo.
