Will £400 supermarket solar panels save you money? The expert guide

Plug-in solar panels will become legal in the UK from 27 August, opening the way for retailers to begin selling the small-scale solar units to the public. Touted as a cheaper and more convenient way to generate electricity for households than fixed rooftop solar power systems, retailers like Lidl, B&Q, Currys and Amazon are among the companies that have been working with the Government on plans to bring plug-in solar to the British market.

However, shoppers may not find plug-in solar panels on shelves as soon as the regulations change. Retailers are in the process of sourcing products that meet the Government’s new safety requirements, and most of the companies involved have yet to announce a product range, price or firm launch date.

Ben Gallizzi, energy expert at Uswitch.com, explains what we know about plug-in solar panels so far, including how much you can expect to pay, how they work and how much you may be able to save on your electricity bill.

Why you should ‘use less electricity’ during the solar eclipse

The UK’s biggest household energy supplier has asked customers to use less electricity during Wednesday’s solar eclipse.

Octopus Energy warned that solar power will “plummet” during the big event.

Solar eclipse on the way

More than 90 per cent of the sun will be obscured by the moon between 6.17pm and 8.06pm on Wednesday.

Protect your eyes

It’s the most the sun has been blocked above UK skies since 1999’s total eclipse.

Use less electricity

“Switch off, head outside and be in nature”, said Octopus Energy, explaining it would take the strain off the grid.

Free hour of power

  • Octopus customers who use less electricity than normal for at least 30 minutes during the eclipse will get a free hour of power on Sunday.
  • The eclipse falls at a “very busy time” for consumption as people make dinner, boil the kettle and watch TV.
  • The UK has to “fire up extra fossil-fuel-run power stations” at busy times, which is expensive, said Octopus.

Summer boost for solar

While the moon blocks the sun, solar generation will plummety.

Octopus said solar power generation will fall just as home energy demand spikes during the eclipse. But the renewable source has enjoyed a great summer. Last month, the UK saw the sunniest July on record.

It helped solar power to a new monthly record, providing 14.4 per cent of all electricity over the month – and a peak of 44 per cent of generation for a period on 12 July.

Putin has a sinister new plan. We should all be worried

The last month has seen the fiercest exchange of missile attacks between Russia and Ukraine in more than four years of war. 

But the fighting is in dynamic impasse, with a huge amount of killing and damage on either side with little to show for it. Russia now looks to be trying to shake that up.

What has changed?

In the past week, Vladimir Putin has urged new field commanders to get the job done to seize the whole of Donetsk by the end of the year. 

Lithuania warned a few days ago intelligence services thought Russia could try to provoke allies in the region in the next few weeks. This points to a dangerous new phase of the war.

The sinister new plan

Russia is using three lines of attack to break the will of Ukraine: to bring misery, a lack of power and utilities with the onset of winter and to grind down the forces on the front line.

The new military appointments and exhortations suggest Putin intends to intensify ground attacks in Ukraine.

What does this mean for Ukraine?

  • The numbers look bleak for Ukraine going into the winter.
  • The trashing of its cities, including the targeting of filling stations, aims at depriving Ukrainians of heat and comfort, and even adequate food.
  • Ukraine is fighting back hard, but the next phase of the war could stretch it to breaking point.

Why you shouldn’t use your 1999 solar eclipse glasses

With a rare partial solar eclipse later today, many are casting their minds back to the last major eclipse over the UK before the turn of the century.

But experts have warned people not to re-use glasses bought for the astronomical event 27 years ago.

What you need to know

Many parts of the country will experience more than 90 per cent coverage of the Sun.

Depending on your location, it will occur between 6.15pm and 8pm. People in the south-west of England are likely to get the most coverage. For the best view, it is a good idea to head to high ground.

When will this happen again?

There has been a last-minute rush for eclipse glasses, as many high street shops and online retailers have sold out.

The next total solar eclipse over the UK will not happen until 2090.

How solo working is driving rising hours spent alone

Working from home and other solitary working habits are a bigger driver of loneliness than screen time, research suggests.

Rear view of woman having a video call meeting with business team on desktop computer while working remotely from home

What you need to know

  • The Resolution Foundation made the findings by analysing UK Time Use Survey.
  • It found the average number of people doing paid work alone has nearly tripled in under a decade.
  • Working from home accounted for roughly two-thirds of the rise in work done alone.
  • The research found that “paid work is the biggest driver of rising time alone among working-age people”.
  • Parth Pandya, researcher at the Resolution Foundation, said: “If policy makers are serious about improving young people’s wellbeing, then work needs to be part of the debate as much as screen time.”

The story in numbers

15%

Among 18 to 69-year-olds, the average proportion of people who were doing paid work alone in the standard working day increased from five per cent in 2014 up to 15 per cent in 2023.

90 minutes

The biggest change was among men aged 18-29, who spent an additional 90 minutes working alone each day.

This means they spend more than two-fifths of the hours they are awake alone.

What does this mean?

The research said: “It is more solo working, rather than screen time, that has driven the rise in reported time alone.

“Despite likely under-reporting of screen time, time alone for young people is still up. So, something else must be driving it – and the diary data points to a sharp rise in solo working.”

Do some foods leave
you feeling hungry rather than satiated? Experts say there are…

Foods that leave you hungrier

A bowl of cereal and glass of orange juice

More refined cereals are digested quickly, and fruit juice, whilst one of your five-a-day, contains less fibre than whole fruit. This might mean you find yourself hungry again within 1-2 hours of eating this breakfast.

Woman eating colored breakfast cereal in front of laptop, workplace breakfast, quick healthy breakfast in office in the morning.

Swap the orange juice for a whole orange, the cereal for oats and milk or serve it with Greek yoghurt or a boiled egg. This would increase the fibre and protein content; two nutrients strongly linked with fullness.

Foods that leave you hungrier

Shop-bought packs can contain a lot of white rice, which is digested quickly, and the protein content is often modest.

Foods that leave you hungrier

Vegetable soup

On its own, it is often very low in protein and calories, so hunger can return quickly.

Unless it’s loaded with veggies, it’s probably pretty low in fibre.

Snack bars

They are ideal for a quick pick-me-up, but if reducing hunger is what you’re after, it’d be better to swap it out.

Low-fat yoghurt

A full-fat plain Greek yoghurt with berries and seeds tends to be much more filling due to the protein, fat and fibre.

BANGKOK, THAILAND - OCTOBER 17: A "KT Herbalist", a Kratom cocktail made from Kratom, coffee and siamese herbs is seen at Teens of Thailand, a bar in Bangkok's Chinatown on October 17, 2021 in Bangkok, Thailand. In April 2021, the start of Thailand's third and most deadly wave of the COVID-19 pandemic, the Thai government banned the sale of alcohol in restaurants and bars, crippling the already suffering food and beverage industry. With a lack of government aid and support, some bars have shuttered their doors in hopes of reopening post-lockdown, while others shuttered their doors for good. But six months into Thailand's most recent lockdown, Niks Anuman-Rajadhon, owner of Teens of Thailand, a gin bar located in a renovated shophouse in Bangkok's Chinatown, decided that instead of waiting for the government to allow the sale of alcohol again, they would take advantage of Thailand's recent legalization of Kratom. Kratom is a locally grown herbal drug with mild opioid and stimulant effects and was reclassified from a type-5 narcotic to a legal-to-grow herb in August 2021. While Thailand prepares for a tentative reopening on November 1st, the alcohol ban and curfew are set to continue, leaving business owners questioning if the country can revive its suffering tourism industry.

On an empty stomach, it can actually increase your appetite.

What to eat instead

Instead of thinking about avoiding foods, think about what you can add to them.

  • Add beans, lentils or shredded chicken to your vegetable soup and pasta.
  • Thicken your smoothies with Greek yoghurt, chia seeds and oats.
  • Apple slices with peanut butter, yogurt with berries and hummus with oat biscuits are better snack options than a pre-made snack bar.
  • Have alcohol alongside a balanced meal containing protein and fibre.

How to age well
without pain

Will Harlow, a physiotherapist
for the over-50s and author of Independence for Life, shares
the key signs you’re ageing
badly – and what to do about it.

How to know

Ageing well is maintaining the ability to do what you want you want for as long as you want without needing help. Everyone is talking about longevity but what’s the point in living longer if the last decade is painful and you’re [totally] reliant on people?”

The signs to look out for

  • The most obvious early warning sign of bad ageing is pain says Harlow. 
  • Another is losing confidence in doing daily tasks, which can quickly lead to a lack of independence.
  • One call Harlow often receives is people calling after having a fall and struggling to get up.

How to age without pain

Not just stopping

When people retire, they often put their feet up and stop. Your body really is use it or lose it.

Throughout our entire lives, Harlow says we need between seven and nine hours of sleep.

Social isolation

The lack of connection can increase the risk of premature death by
as much as 29 per cent.

Strength training

It really is the proxy for
overall independence.

The more muscle mass you have, the less chance of heart disease, diabetes, falls and even anxiety, depression and dementia.

The brain can be linked to muscle mass too, Harlow says. It’s not just about being able to lift things. It gives you more energy, better sleep and you’ll look and feel better.

How to age without pain

Daily habits

Do short bursts of exercise, between 30 and 60 seconds, in otherwise dead time during the day.

Harlow advises 1.6 grams per kilogram of body weight to stop muscle loss alongside resistance training.

Don’t wait

Harlow finds that many patients put off making a change to their lifestyle until their lives are consumed by pain.

For most people, it’s about reducing the number of times per week you’re exercising, not reducing intensity. 

The three ageing tests to do

  • Lie completely flat on the floor and get back up to a standing position using any technique. This should take less than 10 seconds.

  • See how many times you can sit on the chair and stand back up again in 30 seconds. Men should be aiming for more than 14 times and women 12. 

  • The single-leg stand, which involves standing on one leg and balancing for 10 seconds. Everyone should be able to do that and for those under 65, Harlow asks them to do it with their eyes closed.

What exactly are plug-in solar panels, and how do they work?

Plug-in solar panels are small, portable solar kits that generate electricity and feed it into the home through a standard three-pin plug, rather than being wired in by an electrician. They are also referred to as balcony solar panels because they can be used on terraces, porches or in gardens.

Plug-in solar panels capture sunlight, convert it into usable electricity through a small attached microinverter, and feed that power backwards through a standard wall socket into your home’s electrical circuits to run your appliances and lower your grid energy use.

Gallizzi says: “The plug-in panels will be limited to 800 watts per household circuit, usually generated by a kit of two panels, each typically measuring roughly 170cm by 110cm, although larger single units may become available.”

To give you an idea of what that means for your household appliances, a standard microwave oven uses about 800W while it is on, a kettle 2,000W, a smart TV between 50W and 200W, and a modern LED bulb about 6W to 10W. The new plug-in solar panels might generate 500 to 800 kWh a year – enough to power a fridge and a few small devices during the day.

How much do plug-in solar panel systems typically cost and what’s included?

A plug-in solar kit is expected to cost around £400 and will typically include one or two solar panels, a matching microinverter to convert the DC power to AC, specialised cabling, an AC power cord with a standard 3-pin UK plug and mounting hardware tailored for a balcony, wall or flat roof.

According to Gallizzi, a standard rooftop solar system (eight panels, 3.29kW) could cost around £4,650, or £7,875 including battery storage, but prices vary depending on how many panels your roof needs.

How much will I save on my energy bills – and can I sell unused power?

Government figures suggest a typical plug-in solar kit could save a household £70 to £110 a year, which would mean it could take up to four years to break even after buying plug-in panels. As Gallizzi says: “That’s modest compared with rooftop solar, with Uswitch customers seeing average savings of around £877 a year with a system that includes a battery.”

To get the real benefits of the plug-in solar panels, you need to be at home and using your appliances, because, as Gallizzi explains, “the solar energy instantly powers whatever is running on your circuit, reducing the electricity you buy from the grid. But unlike conventional, professionally installed rooftop solar panels, for which any unused power can be sold back to the grid, it will be a case of ‘use it or lose it’ with the new plug-in panels. Any generated energy that is not used will flow back to the grid without you being compensated.”

Do I need permission from my electricity supplier?

Gallizzi says households don’t need permission from their supplier, but they do need to notify their Distribution Network Operator (DNO), the company that manages the electricity network in their area (found on your electricity bill). “It’s a straightforward step and isn’t likely to be refused,” says Gallizzi.

Anyone in a rented flat or leasehold property should check their tenancy agreement or lease, as balcony installations can still fall foul of rules on external alterations even once the wider law changes.

Are there any building regulations people need to be aware of?

Most plug-in solar kits don’t require planning permission, as they’re generally treated as temporary or removable. The main exception is listed buildings or conservation areas, where it’s worth checking with the local council first.

But as Gallizzi says: “Panels can’t be fixed to timber balconies, timber cladding, or other similar wall materials that might be a fire safety risk.”

Who would benefit most from plug-in solar panels?

Uswitch research shows plug-in solar is likely to appeal most to households who are locked out of rooftop solar, and can’t make structural adjustments to their homes, like renters. According to their research, one in five people (18 per cent) said needing their landlord’s permission was stopping them getting rooftop solar at home.

“They’re also well-suited to homes with a roof that isn’t right for solar, whether it’s the wrong orientation, has heavy shading or a structure that can’t take the weight of a rooftop system,” says Gallizzi.

Those with older homes should make sure that the electrical circuit they’re plugged into is in good, safe condition. Anyone with an older or unusual electrical installation should get it checked before connecting a kit.

Does the direction the panels face make a big difference?

“Orientation still matters, but it’s less critical than with rooftop solar,” says Gallizzi. “A south-facing balcony will generate more electricity over the year than a north-facing one, but because plug-in kits are small and portable, households can move them around for the best light more easily.”

What should consumers look for when choosing a system?

You may be able to find plug-in solar kits from Europe ahead of the UK roll-out, but that doesn’t mean they will be suitable for use in the UK. Gallizzi says to keep the following in mind when shopping for plug-in solar units:

  • Make sure the whole kit is certified, looking out for UKCA or CE marking on the complete product, not just the inverter.
  • Check that the product has anti-islanding protection, which cuts power to the plug automatically if it’s disconnected.
  • Ensure it has a UK-appropriate plug and cable length that is built for the specification and not adapted from a European kit.
  • Look out for manufacturer support and a solid warranty – around 10 years on the inverter, 25 years on the panels – backed by UK or EU-based customer support.
