Japanese policymakers are now looking at rooftop solar panels as land is scarce in the country and agrivoltaics, building-integrated PV (BIPV), and floating solar are still in their infancy, reports <b>Mark Hutchins</b>.
That leaves rooftop PV among the most attractive options for further development of renewables in Japan and the government is responding with a series of new subsidies at central and regional level to further incentivize household solar.
Also speaking at World Smart Energy Week, Kazumi Arai, system coordination manager for Tokyo Metropolitan Government (TMG) noted that while an estimated 70% of greenhouse gas emissions in Tokyo come from buildings, just 4.24% of the city’s rooftops currently have solar installed.
Rooftop solar panel s have been gaining traction in Japan due to their environmental benefits and cost-effectiveness. The government has been actively promoting their installation on residential and commercial buildings through various incentives and subsidies.
Our home solar PV systems and energy storage products are engineered for reliability, safety, and efficient deployment in Polish conditions. All systems include comprehensive monitoring and control with remote management capabilities.
