Is Plug-In Solar Worth It?

From the NoTricksZone

By Paul Homewood

I’ve been looking at plug-in solar panels, which Ed Miliband is planning on legalising – more specifically allowing them to be installed without a qualified electrician.

There are a few YouTube videos, like this one by Jonathan Tracey, who have them installed already.

Here are a few of my observations from his video.

The first concerns the size of the panels. Don’t run away with the idea that they are portable, camping style things. Tracey’s below are the standard 450W size, to all intents and purposes the same as rooftop panels.

He has two to catch the morning sun and another two to catch the afternoon sun:

As a tech geek. I expect he is content to have four of these monstrosities despoiling his garden. I suspect most people won’t feel the same or find anywhere else suitable to stick them. There is also the cost of installing them to consider, if like me you are useless with a screwdriver!

There is also the issue that one of those fences is presumably his neighbour’s. I know what my reaction would be if my neighbour asked to screw one into my fence!

Secondly is this matter of sunshine coverage during the day. Rooftop panels do at least see the sun unobstructed when it is out. A panel on a fence or anywhere in the garden is likely to be in the shade for much of the day. Worse still if next door’s conifers block the sun! Forget about the Government claims of savings, which are based on full sunlight. You would be lucky to get half of the saving in reality.

All three of the videos I have watched stress that you really need batteries to make any sizeable savings, which of course will add to the cost of installation.

Something else that was raised is that it will probably take months to amend all of the regulations before these things become legal. Don’t rush out and buy one from Aldi tomorrow!

In terms of savings from the panels, Tracey reckons he saved about £60 between August and December last year, having installed it in late July. Savings virtually disappear from October onwards, but allowing for April till July, annual savings would likely have been around £150.

The cost of four solar panels is around £1000. However, he only saves this much because he has batteries to store excess solar power. Without these, any surplus power, particularly around the middle of the day, would have to be thrown away. Remember that many homes are unoccupied at those times, so there is very little power consumption.

In short, is it worth spending £1000 to save maybe £100, given all of the hassle involved and the fact that few people have that sort of money lying around?

I think you’re right , it’s not worth it . I looked at traditional solar system for my house which has a large south facing roof getting sun most of the day . Installation would have been in excess of £10k and would save money daily , but I would have needed to run it at least 10 years to recoup cost of installation . After 10 years would the panels still work ? Would installer still be around to fix ? Would the panels survive the winter storms ? Would the panels be obsolete and you couldn’t get service parts for them ?

After 10 years would the panels still work ? PROBABLY,
BUT WITH DIMINISHED OUTPUT. Ours have dropped 12% in 14 yrs

Would installer still be around to fix ? DOUBTFUL.
Ours went bust after 3 yrs.

Would the panels survive the winter storms ? PROBABLY,
IF THEY HAVE BEEN INSTALLED PROPERLY & not hit by BIG hail or flying debris.

Would the panels be obsolete YES

and you couldn’t get service parts for them ? NO.

Inverters typically fail after 15-20 yrs

But they create ‘Green Jobs’ … in China !

That sounds more like industrial or large scale inverters. My experience with the smaller plug in types is 1-2 years of solid use. The small scale stuff doesn’t handle the duty cycles as well. Usually the fan cooling systems fail, then the heat degrades the components.

Here in Colorado’s front range, you don’t have to worry about the lifespan of the panels, because this http://theviews.org/Life%20at%20the%20Views/2025/august-10-2025-loudest-hail-we-ve-ever-heard.html will happen to them long before that happens.

Wow, that’s a killer !!

April 14, 2026 2:53 am

A piece in the UK Telegraph today (behind a paywall) says that the grid operator in the UK is considering how to protect the grid from a surplus of solar generation. Needless to say no-one in power in the UK is in the least deterred by the increasingly obvious fact that this is just not going to work. They are discovering intermittency at last, but their reaction is just to pretend that it doesn’t exist, isn’t important.

Why anyone thinks that its sensible to increase solar on this scale, in the second worst country in the world for solar power generation? Its completely insane. You are guaranteed that power generation will be highest when demand is lowest, and lowest when demand is highest.

And no-one can explain how this is supposed to work after they get all the cars transferred to EVs and home heating moved to heat pumps. And one January or February evening, demand hits 60GW+, solar is zero, wind is under 5GW. Where is the rest coming from? And answer came there none – they don’t know and they don’t care, they are just closing their eyes and pedal to the metal.

Here are some exerpts. Notice how they are sending someone to Washington to tell them how splendidly all this is going and they should follow the UK in its voyage to the land of blackouts! Totally insane.

Energy chiefs are drawing up plans to stop the electricity grid being overwhelmed by solar power this summer.

The National Energy System Operator (Neso) said it would be forced to use “more tools, more often” to keep power networks stable when sunny weather caused surges in energy generation.

This would include paying households and factories to consume excess power for the first time, as well as potentially issuing unprecedented orders to switch off large power stations.

Neso issued the warning as Rachel Reeves travelled to Washington, where she is expected to urge a gathering of world leaders to “follow her plan” to combat the energy crisis caused by the conflict in the Middle East.

At the International Monetary Fund summit, the Chancellor will call for “collective action” while urging countries to embrace net zero to boost energy security.

It means they must balance the system in other ways, such as paying larger power plants to turn off or paying consumers to ramp up demand.

The amount of solar on the grid has more than doubled to 22 gigawatts in the past decade, as households and businesses have sought to cut their power bills by installing rooftop panels.
Grid demand expected to plunge
But this is also leading to less demand for energy on the National Grid.

In its report, Neso said there was a 75pc chance that national demand would plunge to a record low during the late May bank holiday weekend, as households were less likely to be at home.
The previous record low of 12.8 gigawatts was set last May – but grid chiefs expect it could drop to 11 gigawatts this year.

By comparison, passive generation from wind and solar farms could be around 18 to 19 gigawatts at the same time.

The imbalance highlights the challenges posed by a renewables-based electricity grid, where supply becomes heavily dependent on the weather.

One expert also warned it had echoes of the blackouts across the Iberian Peninsula last year, when a chain reaction involving solar farms knocked out power across Spain.

Under Labour’s clean power plans, Mr Miliband is seeking to triple solar capacity across Britain by 2030.

I’m not sure about this. It seems from the Telegraph piece as if part of the problem is that there are many solar installations which the grid operator does not control and therefore cannot issue constraint orders and payments for them to disconnect or turn down. I’m not sure that this is the real situation, its my impression of the implication of the piece and appears from the piece to be why the huge build out of solar will be a big problem.

It would be nice if someone closer to the situation in the UK could confirm or correct this.

How is the heat pump revolution in Britain going?

Since 2019 204,203 have been installed. The greatest increase in numbers occurred in 2024 when 16,284 were installed. In 2025 this fell to 3219. Remember the original target was for 600,000 a
year by 2028.

There are over 22m homes in the country on the gas network. Looks like they are going to be on that network for a very long time

Since 2019 204,203 have been installed. The greatest increase in numbers occurred in 2024 when 16,284 were installed.

2026-2019 = 7 years
204,203 total installed / 7 years = average 29,172/year.

So the greatest increase is below the average increase? Math needs help.

That was 16,284 more than in 2023 whereas the increase in the number installed in 2025 was only 3219. I should have put “an extra” after “when”

Vertical panels. Where I live the sun is up in the sky so most people with panels point them … up toward the sky. Geometrically, these panels are least efficient when the sun is highest. And right after that the sun is behind them so … no little electrons to keep his TV running.

The UK lies mostly around 60 degrees latitude or worse. That means that whenever the sun is up and it’s non-cloudy, the sun is quite near the horizon most of the time. It may be that vertical panels make some sense there, even though the solar panels are mostly useless year-round.

The sun moves north in the summer. Very high in the sky for a while. I was led to believe that the UK is cloudy and rainy most of the winter, and summer. Never been there.

Even if this is a decent idea with a decent payback- it’s going to take a lot of skill and time to make it work and who has that skill and time? Some people can fix their own cars- most of us can’t and won’t. We want more time for our relaxation and just enjoying life- not managing our home power grid. A solution for few, maybe, but not for most.

Instead of hanging these solar panels vertically, they could just tilt them up a little bit and get better coverage. It looks like they have room to do so.

I might get some solar panels for personal use if the electricity prices get too high.

What makes no sense is the national picture. They are planning on installing around 135GW of wind and solar. I think 45GW of that is solar.

So they are going to have, at peak output, around double or triple demand at that point in the day. They have no idea how to manage that.

Then comes the dark winter evenings and the associated dead calms. Then they are going to have, if they are lucky, 10% of demand. They have no idea where the rest is to come from.

This is intermittency, and they have no plans whatever for dealing with it, but still are keeping on trying to run the country off wind and solar. These panels are a tiny symptom of the idiocy of a policy which is bound to result in higher prices and blackouts.

Its insane.

Answer the point above.

However long they last, however much of a great idea this is for individuals under the Miliband plan, the whole scheme of which the panels are part is an obvious national disaster in the making. The panels are a classic of their kind. It may pay individuals to put the things in, but it damages the country by a greater amount than their profit.

Solar is mad project in the UK. There may be countries where it makes some kind of sense in some locations. But the UK is the second worst country in the world for solar power generation. The whole scheme is mad. Its a total denial of physics, climate, engineering, finance.

Let me give an eco example which should make clear to you what is going on here. Its like the so-called social cost of carbon emissions. You drive to work. Its faster and more comfortable than public transport. This is because you do not incur the social costs of driving – the pollution, noise, extra accidents and increased congestion.

The participants in this mad scheme are personally profiting from their part of what will be the destruction of the UK power grid.

I have 2 panels, 175W each, in SW Michigan that I bought for $300 about 5 years ago. I get on average about 1 kWh per day, more in the summer (2.5 kWh/d in June) less in the winter. (really low when covered with snow!) At $ 0.25/kWh (rate here in Kalamazoo), I paid for the system in about three years.

But at the prices of panels now, I think I would pay them off in less than a year.

As far as I can tell, RV type panels are still at about $1/W for under 300W.

April 14, 2026 6:03 am

UK plug in solar systems that don’t require qualified installation will be limited to 800W max.

That’s the full time equivalent of 80W if you can use it all directly, almost an old bright incandescent lightbulb.

Currently that works out at about £175 worth of electricity a year, if you use it all.

Plug in DIY 800W systems seem to be appearing starting around the £500 mark.

You still have to notify your electricity supplier of your plug in system, I’m not sure if the new solar system reg. charge applies £183+VAT.

The payback period may be reasonable but you’re never going to save a fortune, or change the fortunes of the UK economy being hampered by a lack of cheap flexible abundant electricity.

Here in the US these kind of small scale panels are running roughly $1/W for the cheapy 200W set ups.400W sets are about .75/W. 400W inverter runs about 50-60bucks.

So that means at my California price of .50/Kwh I would need to get 2000 hrs of rated use out of them.

For my latitude (35degrees) I get on average about 6.3 solar hrs per day with panels at 25 degrees angle.

That scale will pay for itself in a little over a year of operation and successfully power a laptop and small coffeemaker ….. on a clear day when the sun is at it’s peak. And given my experiences with using solar and inverters on RV’s every year or two, that price point inverter will need to be replaced.

These are nice little toys you can play with on the margin, but not a way to power your life.

Climate science says that both sunlight and back radiation warm the earth equally when w/m2 (power) are equal.

Yet no solar panel will produce power from back radiation, only from sunlight, regardless of w/m2.

How is it that back radiation warms but produces no useable power while an equal amount of sunlight produces both warming and useable power.

How can power warm but produce no work?

Solar panels are designed to work with visible light frequencies. They aren’t designed to work with infra-red frequencies.

Only about 10 to 15% of the energy in visible light is converted to electricity (power), the rest (85%) goes into heat.
100% of the energy in infra-red goes into heat.

plug in solar panels are definitely worth it, assuming a few things.

1) you have a south facing surface to mount them
2) you don’t try to supplant your entire electrical consumption because then you require much more expensive electronics or a battery bank. keep it small. (or add panels during the summer when a/c costs accrue and winter when you can create heat as a dump load)
3) they wont be destroyed by weather.
4) don’t buy the cheapest electronics on the market. your “profits” will all go towards buying your next inverter.

the location of the posts for the fence would suggest that the fence belongs to this person, thus there is little his neighbours can do.
However the biggest flaw is that the panels are installed vertically. Surely a better option would be to mount them on an equatorial mount or an altitude/azimuth mount and use software to track the sun. Of course the downside of that is the significant cost and weight of such an apparatus.
