The Iran war \u2013 and the energy crisis it has triggered \u2013 has fired a rocket under the Labour Government\u2019s need to wean Britain off fossil fuels.\u00a0<\/p>\n
Solar is currently a relatively small part of the UK\u2019s energy mix, accounting for just 6.5% of our electricity supply in 2025. But that\u2019s still significant, and crucially it\u2019s rising. According to the national energy operator (Neso), at the end of January 2026 there was 21.8 GW of solar capacity in the UK across 1,951,000 installations. For context, that\u2019s a lot more than our nuclear capacity which is 6.5GW in the UK, though it provides a more stable, constant supply of power. The solar uptick marks an increase of 13% in the space of a year.<\/p>\n
The capacity added over the last 12 months includes Cleve Hill solar farm in July, at 373 MW \u2013 this is the largest operational solar farm in the UK.<\/p>\n
Between 2016 and 2021, the number of new monthly solar installations averaged about 3,000 per month. Over the past 12 months that has soared to 23,000 installations per month. Roughly 15,500 households every month in the UK are fitting solar panels.\u00a0\u00a0<\/p>\n
And over the course of 2025, 268,000 installations came online, the most new installations in any year. The 2.7 GW of new capacity added in 2025 was the highest annual figure for a decade.<\/p>\n
However, some clouds are on their way.\u00a0<\/p>\n

Nearly 98% of Europe\u2019s solar imports came from China as of mid-2025, and European manufacturers remain 30\u201340% more expensive than Chinese competitors. So what China does on tax rates and tariffs matters.\u00a0<\/p>\n
China\u2019s Ministry of Finance has confirmed that the 9% VAT export rebate on solar panels will be removed completely from 1st April 2026. That is in effect, a one-tenth subsidy for Chinese panels, the source of nearly all our cheap panels in the UK.\u00a0<\/p>\n
For battery products, the rebate will be reduced from 9% to 6% from the same date, then removed entirely from 1st January 2027. Again, China is a major supply of UK batteries.<\/p>\n
Alongside this policy change, some raw material costs for solar are also rising. The price of silver<\/a> \u2013 an excellent electricity conductor \u2013 hit an all-time high in mid-January, double the level it was in September 2025, and nearly 200% higher than the year before. In late December 2025, four leading Chinese silicon wafer manufacturers (the silicon product that is the basis of panels) jointly raised quoted prices<\/a> by an average of 12%.\u00a0<\/p>\n More pertinently for the UK, the Treasury is gearing up for its own tax hike. The current 0% VAT relief on solar installations is set to last until 31 March 2027, after which the VAT rate will return to 5%. You can pretty much guarantee installers will add it to their quotes. On a solar and battery system for a three-bedroom home costing around \u00a311,300, the shift from 0% to 5% VAT would add roughly \u00a3565, according to one provider.\u00a0\u00a0<\/p>\n Heating Up<\/p>\n Frank Gordon, Director of Policy at the Renewable Energy Association, told Byline Times they would be \u201cgreatly concerned\u201d about any increase in the cost of solar installations, as higher upfront prices risk slowing uptake.\u00a0<\/p>\n \u201cThis comes at a time where the combination of supply-side cost pressures and the planned end of VAT relief in 2027 could create a significant barrier for households considering solar.\u201d<\/p>\n Renewable firms and the industry body are opposing the withdrawal of the 0% VAT rate in March 2027 \u201cstrongly supporting\u201d its extension, to make sure people aren\u2019t priced out. It\u2019s a call backed by major installer Geo Green Power. But some perspective is needed.\u00a0<\/p>\n As the firm\u2019s managing director James Cunningham tells me: \u201cThe price of a solar installation has fallen dramatically in the last three years largely due to the sudden growth in the market during the energy crisis and an increase in manufacturing capability to meet demand \u2013 the industry literally tripled in the space of around three years \u2013 and that increase in output with new players entering the market has reduced prices and kept them low.\u201d\u00a0<\/p>\n There are cost pressures coming down the track, but we now have a competitive installation market in the UK that should keep it in check.\u00a0<\/p>\n But there is a potentially much more seismic \u2013 and positive \u2013 change coming which could turbo-charge solar installations in the UK.\u00a0<\/p>\n The Government has just quietly (or at least, with little media coverage) announced that so-called \u2018plug in solar\u2019 will soon be legalised.\u00a0<\/p>\n This is exactly what it sounds like \u2013 people will be able to put solar panels on their balconies and gardens, and plug them directly into their mains supply. The property then draws on that energy first to power the house or flat, reducing energy bills.\u00a0<\/p>\n If that sounds far-fetched, then realise that it is already a big deal in countries like Germany.\u00a0<\/p>\n EXCLUSIVE<\/p>\n Fossil fuel funded think tanks, petrostate-linked policy institutes and oil market insiders are all being presented as impartial observers by the media, reports Nafeez Ahmed<\/p>\n Nafeez Ahmed<\/p>\n Solar Flare<\/p>\n Plug-in solar was first legalised \u2013 or rather, regulated (as it was already happening) in Germany in 2019, allowing balcony solar systems to use standard electrical plugs and feed into the grid.<\/p>\n The rules were then significantly liberalised in 2024, followed by a landmark renters\u2019 rights change. In October 2024, a new law gave renters and flat owners across Germany a legal right to install balcony solar systems. Landlords are now obliged to approve requests and can only refuse in exceptional, documented circumstances.\u00a0The tenants then save up to a quarter on their electricity bills, depending on their usage and number of panels. \u201cThe system pays for itself very fast, within about three to four years,\u201d Sebastian M\u00fcller of the NGO BalkonSolar tells Byline Times.<\/p>\n The results have been astonishing. There are now over a million registered \u2018plug in solar\u2019 installations in Germany, but potentially several million more not formally registered with the grid, M\u00fcller says. He and his group led the successful push for renters to be able to install them easily.\u00a0<\/p>\n The UK Government has commissioned a safety study into how it would work in the UK, due to report in the next couple of months. Some key questions therefore remain unanswered. If the Government requires a qualified electrician to sign off every installation, then that would dramatically reduce uptake. And with a large proportion of Brits renting, the question of whether landlords can block installations \u2013 and on what grounds \u2013 will need clarity.\u00a0\u00a0<\/p>\n But the potential is there. Low cost solar panels that families can buy at supermarkets and put on their balconies or outdoor space will be made available in the UK for the first time, potentially within the next year.\u00a0The likes of Aldi and Lidl selling cheap, easy-to-install devices could transform the market. <\/p>\n Self-appointed press regulator IPSO initially refused to investigate the paper, until polling suggested that nearly two-thirds of readers had been misled<\/p>\n Josiah Mortimer<\/p>\n Brighter Days?<\/p>\n In his energy crisis speech on Monday, the Prime Minister mentioned an \u2018Energy Independence Bill\u2019 on its way. This was mentioned in the last King\u2019s Speech in 2024 but seemed to have fallen off the agenda. It\u2019s now heading right to the top, and not before time. <\/p>\n The Department for Energy Security and Net Zero said that any decisions on the VAT hike would be made at the next fiscal event. But liberalising laws on plug-in solar, alongside other measures to boost uptake by households and businesses, will likely have a greater effect.\u00a0<\/p>\n Britain is not famous for its sun. But neither is Germany, and London is south of Berlin. Manchester is slightly south of Hamburg. As Sebastian Muller tells me: \u201cYou might actually have comparable levels of sun to Bavaria, in places like Brighton and [across] the south coast.\u201d\u00a0<\/p>\n There is a big opportunity here to save millions of pounds for households, reduce dependence on fossil fuels, and create a more decentralised, localised energy system. The best time to do it was, of course, before Donald Trump\u2019s Iran war.The next best time is now.<\/p>\n A Government spokesperson told Byline Times: \u201cWe have the right economic plan. Our \u00a315 billion Warm Homes Plan will roll out upgrades including solar panels to up to five million homes, saving families hundreds on energy bills, and qualifying installations of energy-saving materials will continue to benefit from a reduced [though still higher than current 0%] rate of 5% VAT after March 2027.\u201d<\/p>\n Got a story?
