The Declaration

In 2025, global solar PV capacity approached 3 terawatts, with more than 600 GW of new capacity installed worldwide during the year. Solar supplied around 12 per cent of global electricity consumption for the first time, and PV once again accounted for more than 75 per cent of new renewable generation capacity added globally in 2025.

This is an energy revolution. But it is not yet shared equally.

Too many households still face high power bills, unreliable supply and dependence on volatile fuel markets. Too many communities see the clean energy transition happening around them, but not for them. Too many countries have the sunshine, the rooftops and the demand — but not yet the finance, grids, rules or workforce to turn that opportunity into power.

That must change.

Rooftop solar is one of the fastest ways to put the benefits of the clean energy transition directly into people's lives. It can cut household energy costs, strengthen energy security, reduce emissions, ease pressure on grids, create skilled local jobs and build public confidence in climate action.

The world has already proved solar can scale. Now we must prove it can serve people.

We, the Participants in the Global Rooftop Solar Declaration, will work together to enable at least 300 million households worldwide to be powered by rooftop solar by 2030.

This is a promise to make the clean energy transition visible at the kitchen table, on the family budget and in communities.

It is a commitment to move faster than business as usual.

It is a commitment to make rooftop solar a mainstream national energy priority — not a niche program, not an aspirational product, and not an afterthought in electricity planning.

The economics have changed. Renewables are now the most cost-competitive source of new electricity generation in most markets. In 2025, more than 90 per cent of newly commissioned utility-scale renewable capacity produced power more cheaply than the lowest-cost new fossil fuel alternative, while solar PV reached a global weighted average cost of around USD 0.044/kWh. The cost of electric appliances and vehicles has declined dramatically, making it easier for households to switch to technologies that can draw directly from their rooftop power, reducing both emissions and bills.

The deployment curve has changed. The International Energy Agency projects that renewable power capacity will increase by around 4,600 GW between 2025 and 2030, with solar PV accounting for almost 80 per cent of that growth. Distributed solar — including residential, commercial, industrial and off-grid systems — is expected to account for around 42 per cent of total solar PV expansion this decade.

The politics have changed too. Families want cheaper bills. Countries want energy security. Communities want jobs. Governments want visible results. Rooftop solar answers all four.

Global momentum is building around the electrification of transport, industry, and buildings. Access to low-cost rooftop solar can accelerate economy-wide electrification by providing a gateway to making electric technologies more affordable and attractive than fossil-fuel alternatives, while helping to manage demand on distribution networks.

To deliver 300 million solar homes by 2030, we will act in six areas:

We will cut unnecessary red tape and make it faster, simpler and cheaper for households to install rooftop solar.

This includes clear permitting rules, faster approvals, transparent grid connection processes, fair metering arrangements and consumer information people can trust.

We will treat rooftop solar as core energy infrastructure.

That means including distributed solar in national energy planning, grid planning, climate strategies and energy affordability policies.

We will work with public and private finance institutions to reduce upfront costs and expand access to affordable finance for rooftop solar and household electrification.

This may include low-interest loans, credit guarantees, pay-as-you-save models, concessional finance, aggregation platforms, leasing models, rebates, subsidies and targeted support for households that cannot otherwise afford installation.

We will invest in distribution networks, storage, smart inverters, demand flexibility and digital systems so electricity grids can manage high levels of rooftop solar safely and reliably.

Rooftop solar must be backed by modern grid rules, not held back by outdated ones.

We will design programs that reach low-income households, renters, apartment residents, public housing tenants, those with no electricity access, remote communities and households without suitable rooftops.

Where rooftop ownership is not possible, countries should provide practical alternatives such as community solar, shared solar, solar on public buildings and local energy schemes.

We will expand training, certification and safety standards to create skilled local jobs in installation, maintenance, electrical work, storage, energy management and related services.

Distributed solar is labour-intensive, local and visible. Done well, it can build a clean energy workforce in every region.

We will cooperate to move faster by sharing what works.

Participants will support practical collaboration on:

1. 1.rooftop solar policy design
2. 2.finance models for households
3. 3.grid integration and storage
4. 4.consumer protection and safety
5. 5.training and workforce standards
6. 6.data and deployment tracking
7. 7.access models for low-income and underserved communities
8. 8.city, state and regional delivery partnerships

The Declaration is open to endorsement from all levels of government – recognising the leadership local councils, cities, state/provincial governments and national governments are playing. This Declaration does not impose a single model. Signatories will act according to their unique circumstances, energy systems and capabilities.

But it does set a shared direction: rooftops must become a major platform for global clean energy deployment.

By 2030, rooftop solar can help power hundreds of millions of homes.

It can help families lower their bills – especially when combined with electrification

It can help countries cut dependence on imported fossil fuels.

It can help cities manage rising electricity demand.

It can help developing and emerging economies expand clean energy access without waiting for every kilometre of new transmission to be built.

And it can show citizens that climate action is not only about targets and summits — it is about practical benefits in daily life.

So today, in Antalya, we call on governments, cities, regions, financial institutions, utilities, industry, workers and civil society to join us.

The Global Rooftop Solar Declaration is a voluntary, non-binding international declaration that brings together governments to accelerate rooftop and household solar deployment worldwide. It aims to help deliver 300 million solar-powered homes by 2030 and make solar homes a central part of the global clean energy transition.

The global energy crisis makes the case for solar even clearer. Solar is the most affordable power in human history. Solar homes are the way we give every person the opportunity to participate in the solar revolution. Yet policy, finance, regulatory and market barriers continue to slow deployment in many countries. The Declaration is designed to help governments work together to overcome those barriers.

Solar homes are small-scale solar solutions that provide electricity directly to homes and the communities around them. This includes systems installed on houses and apartment buildings, like rooftop, balcony and plug-in solar, as well as systems serving small businesses and community buildings such as schools and libraries. Solar homes can operate with or without storage, although adding storage can significantly increase reliability, resilience and energy independence.

Unlike many energy investments, solar homes deliver visible benefits directly to households and communities. They can often be deployed quickly, creates local jobs, reduces pressure on electricity networks and gives people a direct stake in the clean energy transition. Better yet, they are a resilient power system that keeps the lights on even when extreme weather or natural disasters damage energy grids.

Solar homes work for all kinds of communities. A household in rural Kenya, an apartment block in Jakarta, a community in rural Australia. That universality is what makes solar homes a uniquely powerful tool in the global energy transition.

Rooftop solar is expected to make up 34% of the added renewables capacity up to 2030. It is therefore a key way to achieve COP28's 3xRenewables target (global target to triple renewable energy by 2030). The Declaration is designed as a practical implementation initiative that can support international efforts to accelerate renewable energy deployment and deliver tangible outcomes beyond formal negotiations.

The Declaration supports the ambition of powering at least 300 million solar homes by 2030. This is double the estimated current number of solar homes.

Current deployment trends are not expected to reach the scale needed to fully realise the economic, social and climate benefits of solar homes. The 300 million target is designed to accelerate ambition, close the deployment gap and make solar homes a recognised pillar of the global clean energy transition

No. The Declaration is entirely voluntary and non-binding. It does not create legal obligations, emissions targets or enforcement mechanisms. Participants decide for themselves how they will contribute based on their own circumstances and priorities.

The Declaration is aimed at national governments, but is also designed to recognise the important role of local, state and provincial governments, who may want to see their national government have a more ambitious and structured approach to making it easier and cheaper for people to connect a solar and battery system to their home.

Participants commit to supporting solar homes and to sharing experience, policies and practical solutions with other governments. They are encouraged to advance action in areas such as finance, grid integration, workforce development, consumer protection and access for underserved communities.

The Declaration focuses on six priorities:

1. 1.Making rooftop solar easier
2. 2.Putting households at the centre of energy policy
3. 3.Unlocking finance for families
4. 4.Modernising grids for distributed power
5. 5.Making the transition fair and accessible
6. 6.Building a skilled workforce

These six actions address the most common barriers to scaling solar homes worldwide.

Governments at any level can endorse the Declaration, champion solar homes domestically, share lessons with other participants, develop enabling policies and support practical implementation efforts suited to their national circumstances.

Signing is voluntary, and the declaration is non-binding. Governments may endorse at any time, and there are no mandatory reporting obligations or financial contributions required.

Steps for interested governments are:

1. 1.Endorse the declaration
2. 2.Nominate a focal point and ask them to email the 300 Million Solar Homes Director
3. 3.Organise a briefing for officials on the Declaration
4. 4.Participate in knowledge-sharing activities.
5. 5.Consider national actions aligned with the declaration.

The 300 Million Solar Homes team and the Global Solar Council can provide a briefing for government officials or representatives interested in learning more.

Industry groups, financial institutions, development organisations, utilities, civil society organisations and research institutions can support implementation through finance, policy advice, technical assistance, workforce training, public engagement and project delivery.

No. Solar homes are a solution any country can deploy today, regardless of income level or existing infrastructure. In fact, developing and emerging economies stand to benefit most. Many have some of the world's highest solar potential, face the steepest costs from imported fossil fuels, and can expand clean energy access without waiting for large-scale transmission networks to be built. For these countries, solar homes mean lower bills, reliable power and local jobs.

The Declaration recognises that not everyone can build solar homes. It encourages governments to support alternatives such as community solar, shared solar, solar on public buildings and other local energy solutions that broaden access. The solar revolution is bringing new technologies online every year, like Plug-in Solar, that allow more people to participate.

No. Solar homes are intended to complement, not replace, other parts of the energy transition. The Declaration recognises the need for continued investment in grids, utility-scale renewable energy, electrification and broader decarbonisation efforts. To reach 3xRenewables, we need 11 TWs of installed renewable energy capacity, of which 300 Million Solar Homes will contribute 2 TWs. That said, creating a policy environment that supports solar homes is one of the fastest ways we can reach the 3xRenewables target.
