Technical FAQs 3

How much does electricity cost in Tokyo in 2025?

Electricity is the long-term expense that can really add up. In Tokyo in 2025, the average tariff is between ¥30 and ¥40 per kilowatt-hour before subsidies. The government continues to provide seasonal rebates for energy-efficient appliances, so choosing a unit with a high APF (Annual Performance Factor) rating can significantly lower bills.

What is a solar inverter used for?

This Inverter is very suitable for solar power systems, wind power generation systems, wind and solar hybrid generation systems. The inverter can supply AC power to all kinds of electric equipment, air conditioners, electric motors, refrigerators, fluorescent lights, televisions, electric fans and other industrial power supply.

How many kW is a Japanese air conditioner?

In Japan, air conditioner capacity is measured by tatami size instead of BTU. For example, a 6-tatami unit is about 2.2 kW, which is suitable for small bedrooms, while a 14-tatami living room unit exceeds 4 kW. Prices rise steeply once you go beyond 3.6 kW, partly because at that point a 200V outlet becomes mandatory.
