300 Million
Solar Homes
The future of affordable energy
By the end of 2026, the world will have installed approximately
150 million rooftop solar systems. As people, governments and
the industry working together, we can double that number by
2030 bringing affordable, reliable and resilient energy to more
than one billion people. We are working with countries, cities,
communities and industry to deploy 300 million rooftop
solar and battery systems by 2030.
The Journey
It took 70 years for the world to install its first 150 million solar rooftops – the next 150 million can happen much faster.
Installation of household and rooftop solar systems are already growing rapidly around the world. The challenge now is to remove the barriers that still make it too slow, too expensive or too difficult for millions of families and small businesses to access this source of energy.
300 Million Solar Homes is an alliance with a vision – we believe in a world where every person no matter where they live has the right and opportunity to choose, connect and store solar energy from their roof, balcony or in their community. This mission is urgent, particularly in those places where electricity demand is rising quickly and the need for affordable, reliable power cannot be ignored.
WHY IT MATTERS
Household solar can make everyday life a little easier
Solar on homes, shops, schools, clinics and community buildings puts power close to the people who use it. The benefits are practical and immediate.
02 More Reliable Power
Solar - paired with a battery system where possible - can keep homes, businesses and essential services running when the electrical grid is under pressure.
03 Local Jobs & Opportunity
More rooftops mean more work for local installers, electricians, distributors, technicians and small businesses.
04 Cleaner, Fairer Growth
Household solar panels and batteries can meet rising electricity needs with clean power while giving more people a direct stake in the energy transition.

Five ways to turn ambition into solar homes
Reaching the 300 Million Solar Homes goal won’t happen through a single policy, program or investment. It takes action across government, cities, finance and energy systems. These five focus areas work together to make solar and batteries simpler, more affordable and more accessible for households and communities around the world.
