UK Home Solar Hits New Heights in 2025 and Gets New Warm Homes Plan But Watch Out…
UK solar has been doing great since the prior government killed feed in tariffs and the market bombed 10 years ago. In the last 5 years UK installs have grown 9X off that low base from 25,000 installs in 2020 to 228,000 in 2025 (OpenSolar estimates). This 5 year success is without subsidy , with a market businesses can invest in, knowing the economics of solar with batteries allows customers to save money and businesses to make a profit selling those systems.

The UK needs to think bottoms up this Christmas, not more top down.

How to solve 80% of climate: just digitise the grid and let solar fly! I love the global village that is COP, especially in the polarised, war-mongering world we’re now in. Honestly, it is quite beautiful mingling with all the cultures and peoples of humanity, together physically in one venue – I met scores of amazing, caring people – it’s an environmentalist’s mecca and a beacon of hope for multilateralism. I felt really proud to be a sponsor of the Global Solar Council’s 10

Solar Down Under: Australian Solar Visit
From an inspiring visit to India with 70% solar growth and an ambitious 10m rooftop program, to a week in Australia - another solar star country! We’re seeing huge growth in battery adoption to add to the 35% solar penetration. Aussie pros have installed 2GWh of distributed battery installs in just the first 4 months of the new battery initiative! The market feels a little scarily hot right now so watch out everyone (I’d prefer a market-driven policy to de-risk this) but the
