The key highlights of the brief “Zero carbon, zero cost: Rooftop solar savings for Japanese households” by Zero Carbon Analytics are:

● The 1.5°C Paris Agreement target is at risk. Deploying renewables is key to keeping temperatures down and mitigating the risks of extreme weather events. 

● If countries do not act quickly, not only will climate impacts worsen, but governments, businesses and households will also miss out on savings from transitioning to cleaner fuels. 

● Wind and solar are two proven technologies that are the most effective at cutting power sector emissions while increasing electricity supply. Modular solar technologies offer a number of benets at the household level. 

● Policy interventions such as tax credits and feed-in-tariffs, have been shown to increase adoption of rooftop solar across the UK, EU and US.

● Zero Carbon Analytics calculated that Japanese households with solar panels in FY 2020 would have saved on average nearly 135% compared to those without, receiving a net benet of JPY 37,422. 

● Households saved over JPY 143,000 in total from reductions in electricity bills and payments from the sale of excess solar power.
