Many consumers want to know how long it will take them to make back the upfront costs of solar.

Europe’s reliance on imported fossil fuels has come under fire since the Iran war sparked a new energy crisis
The IEA chief Fatih Birol said this week that "no country will be immune to the effects of this crisis”.

Dynamic tariffs are becoming more common in Europe
This is where the price of electricity varies throughout the day and night, with costs going up during peak periods, like dinner time, when households are using more
This means that if you store up solar power during daylight hours, when the sun is at its strongest, then you can use that energy, rather than drawing it from the electricity grid, during the most expensive periods
“Your relationship with the grid is totally changed,” says Clayton.

Are solar panels worth if you don't live in a sunny country?

Spain is leading the way in weaning itself off imported fossil fuels by investing in renewables, thereby reducing prices for consumers
“Spain’s wind and solar growth has reduced the influence of expensive fossil generators on the electricity price by 75 per cent since 2019
This decline in the hours where the electricity price was tied to gas power cost was faster than in other gas-reliant countries, such as Italy and Germany,” according to energy think tank Ember.

How long does it take to make back the cost of plug-in solar?

For the many Europeans who live in apartments or other types of accommodation where they don’t own the building, rooftop solar is not realistic
That’s where plug-in solar comes into its own
Plug-in solar fitted to balconies is especially popular in Germany, with more than a million sets installed between 2022 and 2025
The price halved during the same period, with small models costing around €200 and large ones that include storage costing less than €1,000.

According to Solar Power Europe, it takes an average of two to six years to recoup the cost of the system, depending on what you paid for it, its size and where you mount it.

“This makes solar feel suddenly reachable for everyone
I love how it turns something complex into something as simple as plugging in a device
Suddenly energy independence feels practical,” says entrepreneur Sara Kukovec
Others are already thinking up ways to make them work on houses without balconies, with patent attorney Ed Clarke enthusing, “This sounds amazing
“Before purchasing or plugging in any off-the-shelf generation product, householders should have their electrical installation checked by a competent electrician
Professional verification is the only way to be sure.” says Mark Coles, Head of Technical Regulations at the Institution of Engineering and Technology
