Plug-in solar panels could save a typical UK household £1,100 over their 15-year lifetime, according to Carbon Brief analysis.

In response to the ongoing energy crisis, the UK government announced on 15 March a package of clean-energy measures to “boost” energy security.

Among these was the introduction of “plug-in” solar panels to the UK, which would be available “within months” at retailers, according to the government.

A cost-benefit analysis by Carbon Brief finds that plug-in solar could provide 400 kilowatt hours (kWh) of electricity each year, enough to meet 15% of demand for a typical household.

This could save £110 on electricity bills each year, meaning the typical upfront cost of around £500 for an 800-watt (W) system could be paid back within five years, according to the analysis.

Assuming the plug-in system has a 15-year lifespan, total net savings could reach £1,100.

Plug-in panels

Compared to rooftop solar, smaller plug-in solar systems consisting of one to two panels can be easily installed on balconies, in gardens and other outdoor spaces. They can be plugged directly into home sockets without the need for additional wiring, reducing electricity taken from the grid and thereby cutting bills.

Plug-in solar has already taken off in Germany, with official registrations already exceeding 1m installations (the actual number could be up to 4m). Other growing markets include France, Spain, the Netherlands and the US.

Panels could be available in the UK “within months” at retailers, such as Lidl and Sainsbury’s, according to the government. (Many of the products from EcoFlow, one of the main providers of plug-in solar in the UK, are already sold out online.)

The government said it will work with relevant bodies to update electrical regulations to allow the use of plug-in solar. The Institution of Engineering and Technology (IET) has advised homes to get their wiring checked before installing.

Costs and benefits

To assess the potential impact of plug-in solar, Carbon Brief conducted a cost-benefit analysis for an 800-watt (W) installation in a typical two-to-three bedroom home in London. The assumptions are approximate and will vary for different locations and set-ups.

Optimally placed panels – south-facing and tilted at around 40 degrees – would generate around 820 kilowatt hours (kWh) each year in London – at a “load factor” of 12% – according to the EU’s PVGIS database.

Actual output is likely to be lower, due to sub-optimal placement – such as vertically on balconies – as well as orientation and shading.

A report by trade body Solar Power Europe noted these factors could cut 30-60% from optimal output. This analysis assumes a 45% reduction from optimal output.

If a household is able to use 90% of the output – typical for such installations – then the panels would provide 400kWh of electricity each year, enough to meet 15% of typical demand.

This will vary on the household usage patterns, but running appliances such as washing machines during peak daylight hours could improve capture rates.

This could save £110 on electricity bills each year, meaning the upfront cost of around £500 could be paid back within 5 years, according to Carbon Brief’s analysis.

Assuming the panels last 15 years, total net savings over their lifetime could reach £1,100.

These savings assume a fixed unit cost of 27p/kWh, based on predictions for July 2026.

If electricity prices surged to 34p/kWh for a prolonged period – as they did during the 2022 gas price crisis – then annual savings could increase to around £140, further reducing the payback time.

If module costs fall over time as more suppliers enter the market, this could reduce the upfront cost and payback time.

If 3m households take up plug-in solar – comparable to Germany’s current deployment – this would generate 1.2 terawatt hours (TWh), less than 1% of UK demand.

While this would not significantly cut UK emissions overall, it could still save the households more than £330m in total and avoid around two tankers’ worth of imported liquified natural gas (LNG) each year, according to Carbon Brief’s analysis.

Unlocking participation

Aside from its economic benefits, plug-in solar could unlock participation in the clean-energy transition for a wider percentage of the population.

For example, renters make up around one-third of UK households and lack control over the installation of rooftop solar and heat pumps. Plug-in solar would enable them to engage in and benefit from clean energy in their homes.

Analysis: How ‘plug-in solar’ can save UK homes £1,100 on energy bills

Alicia Johnson, the first Black woman ever elected to statewide office in Georgia, discusses rate hikes, transparency and her priorities for the Georgia Public Service Commission.

By Ryan Krugman

The Georgia Public Service Commission has approved six rate increases in three years and signed off on a sweeping expansion of fossil fuel infrastructure, decisions that have reshaped Georgia’s energy landscape and contributed to rising electric bills for many households. Alicia Johnson, who holds a PhD in business administration, hopes to chart a different course.

Georgia’s New Public Service Commissioner Says She Will Put Affordability and Transparency First

Faced with long queues and eye-watering prices, filling up has been a painful experience for South Asia’s many self-employed drivers since the Iran war unleashed turmoil in global energy markets.

But in Nepal, above-average rates of electric vehicle (EV) adoption among minivan drivers like 52-year-old Gyanu Pattel have helped to soften the blow.

A year ago, Pattel swapped his Tata Sumo diesel SUV for a 10-seater electric van, which he uses to shuttle passengers 140 km (87 miles) back and forth from Birgunj near the Indian border to the capital, Kathmandu, each day.

Daily charging costs him $9, much less than the $45 he used to spend on diesel. While he also spends $600 a month paying off the loan for the van, he told Climate Home News that his income is sufficient and that in five years’ time, he will have paid it off.

“If I didn’t get enough passengers, I would incur losses,” he said, “Now I save on fuel and maintenance costs.”

Himalayan hydropower

While still a small market in global terms, Nepal is a leader on rates of EV adoption.

Nearly three-quarters of new cars sold in the country are now electric, 2025 customs data shows, one of the highest rates in the world. In neighbouring India, EV sales currently account for about 5% of the total market.

Sales of electric motorbikes, three-wheelers and minivans have also risen sharply since about 2020.

While Nepal has no oil or gas production of its own and is dependent on imports to meet its fuel needs, it has plentiful supplies of electricity generated by hydropower, making EVs a no-brainer for policymakers.

Bruised by previous oil supply crises, Nepal’s government has introduced policies to encourage EV adoption. When Russia’s 2022 invasion of Ukraine drove up fuel prices, the Nepali government cut the import tax for EVs to 43% compared with 257% for a petrol or diesel car.

At the same time, charging stations have sprung up across the country as a result of investments by the private sector and development aid.

No more panic

Nepal’s EV boom has brought multiple benefits beyond cutting air pollution and helping the country progress towards its goal for net-zero emissions by 2045, advocates say.

Reducing the country’s fuel needs is a way to shield its foreign currency reserves from spikes in global oil prices.

Electric minivans like Pattel’s have also helped improve public transport. For drivers like him, lower running costs mean they are more willing to leave with empty seats, meaning passengers have shorter waits and more comfortable journeys.

Above all, it cushions the impact of oil shocks like the current crisis triggered by Iran’s effective closure of the Strait of Hormuz, through which a fifth of the world’s oil and liquefied natural gas supplies flowed previously.

“Unlike in the past, rising petroleum prices do not create panic because there are alternative options,” said Sauden Badal, business developer at EV import company Shasheela Motors, which has an EV charging network across the country of 30 million people.

He said Nepal’s target to reach net zero by 2045 had convinced people that “the future is electric vehicles”.

Stung by past shocks

It was a major fuel crisis in 2015/2016 that helped kindle Nepal’s EV revolution.

A row between Nepal and India led protesters to block trucks carrying fuel from India into Nepal, causing months of acute shortages that prompted many Nepalis to shift to pedal-powered and electric two-wheeled vehicles.

Recalling that crisis, Bijay Lama, the driver of a 17-seater electric microbus, told Climate Home News he remembered waiting hours for diesel. This time around, he said, people are far less concerned about the fuel price hikes.

“Now, EVs have reduced such problems,” he said as he loaded a passenger’s luggage onto the roof.

In the early days of the country’s EV roll-out, finding a charging point was a concern, said Anil Chaudhari, who drives a 14-seater electric microbus. Today there are charging centres every 20 minutes on main roads and in urban areas.

“Charging facilities are available in almost every sector. I have travelled from east to west of the country driving an EV and I did not face any problems,” he said.

Nepal had just over 1,500 charging stations by the end of 2025, up from just 50 five years earlier, according to data from the Energy Ministry.

Long road ahead

Despite the progress so far, much more remains to be done, said Maheshwar Dhakal, head of the Environment Ministry’s climate change management division.

While smaller buses are going electric, bigger ones travelling long distances still mainly run on petrol and diesel, Dhakal said.

“Policies need to be reviewed and discussions will continue,” he said.

Jeevan Banjade, vice chair of West Nepal Bus Operator Limited, a major bus operator and association, urged the government to reduce customs duties on electric buses, EV batteries and spare parts.

He added that once works were completed on major roads, the private sector would invest in large electric buses.

Public investment is also needed to improve the nation’s electricity infrastructure. While Nepal produces plenty of electricity from hydropower in its mountains, transporting it to urban hubs like Kathmandu where it is needed is a challenge.

“We need to invest heavily in infrastructure such as transformers, transmission lines and distribution systems,” Ram Prasad Dhital, chair of the Electricity Regulatory Commission, told Climate Home News.

“If we can do this, our dependency on fossil fuels will decrease.”
