Are solar panels and inverters safe in Japan?

In Japan, solar panel and inverter manufacturers must adhere to specific certifications to ensure their products meet safety and performance standards. The Japan Electrical Safety & Environment Technology Laboratories (JET) provides certification for photovoltaic power generation systems, including solar panels and inverters.

Why do Japan import solar inverters?

Solar inverters, essential for converting DC electricity (produced by solar panels) into usable AC electricity, are imported into Japan at a 0% duty rate. This lower tariff helps keep the cost of adopting solar energy systems affordable for businesses and consumers in Japan.

Are Lonseal waterproof sheets suitable for Roof greening?

Lonseal waterproof sheets have high root resistance and are suitable for roof greening. We established the "solar panel installation construction method" for installing solar panels simultaneously with waterproof construction.

What certifications are available for solar panels & inverters?

The Japan Electrical Safety & Environment Technology Laboratories (JET) provides certification for photovoltaic power generation systems, including solar panels and inverters. Another important certification is the JIS Q 8901, a standard for the reliability and durability of solar modules in different environmental conditions.

Are waterproof sheets suitable for Roof greening?

The absolute requirements for roof greening is the usage of a waterproof sheet that is durable enough to prevent intrusion and penetration of plant roots. Lonseal waterproof sheets have high root resistance and are suitable for roof greening.
