With UK energy prices remaining volatile and expected to increase by around 20% in July, households across the South East are feeling the pressure. More homeowners are now asking a critical question:
“Does investing in solar still make financial sense in 2026?”
At SolarTherm UK, we’ve been installing solar panels and battery storage systems since 2010 across Essex, Kent and the wider South East. In that time, we’ve seen energy markets shift dramatically – but one trend has remained consistent: solar gives homeowners control, stability and long term savings.
This guide breaks down the real relationship between solar energy and rising electricity costs – and whether now is the right time for you to invest.
The Reality of Rising Energy Prices in the UK
Energy costs in the UK have seen sustained increases over recent years due to:
- Wholesale gas price volatility
- Geopolitical supply constraints
- Grid infrastructure pressures
- Environmental policy transitions
Even with temporary price caps and government interventions, the long term trajectory is clear: electricity prices are unlikely to return to pre-2020 levels.
For homeowners in the South East – where energy demand and property sizes tend to be higher – this creates a strong case for energy independence.
How Solar Protects You from Price Increases
A solar PV system allows you to generate your own electricity, reducing your reliance on grid power.
Key Financial Benefits:
- Immediate bill reduction – use your own generated electricity instead of buying from suppliers
- Long term price protection – lock in a portion of your energy costs for 30 years or more
- Export payments – earn money through Smart Export Guarantee (SEG) tariffs
In simple terms, every unit of electricity you generate and use yourself, is one you don’t have to buy at rising market rates.
The Role of Battery Storage in 2026
Solar alone is powerful – but when combined with battery storage, it becomes transformative. Battery systems allow you to store surplus energy generated during the day to be used in the evening when electricity prices are higher, reducing reliance on the grid even further.
Modern systems, like those we install at SolarTherm UK offer up to 95% usable capacity, backup power capabilities and smwhopart energy optimisation. This is especially valuable as time of use tariffs become more common across the UK.
Is Solar Still a Good Investment?
Short Answer: Yes – arguably more than ever
Here’s why:
Faster Payback Periods
With higher electricity prices, savings accumulate quicker – reducing payback times to 6-10 years in many cases.
Increased Property Value
Homes with solar installations are increasingly attractive to buyers looking for energy efficiency and lower running costs and can see an uplift of up to 14% in some cases.
Energy Independence
You’re less exposed to external market shocks and supplier instability.
Sustainability Goals
Reducing you carbon footprint aligns with both personal values and future regulatory direction.
Why Timing Matters Right Now
Delaying a solar installation comes with a hidden cost: continued exposure to rising energy bills. Every month without solar is another month paying peak electricity rates. Additionally, demand for installations is increasing, and grid application timelines are extending project schedules. While relatively stable now, equipment and component pricing is expected to rise as demand increases. Installing sooner allows you to start saving immediately – and lock in current prices.

FAQs
How much can I save with solar in the UK?
Savings vary by system size and usage, but most homeowners reduce electricity bills by up to 80%.
Do solar panels still work in winter?
Yes. While output is lower, solar panels still generate electricity year-round—even on cloudy days.
Is battery storage worth it?
In most cases, yes. Batteries increase self-consumption and maximise savings, especially with rising evening electricity rates.
How long do solar panels last?
Most panels come with 25-year performance warranties and often last longer.
Will energy prices keep rising?
While short-term fluctuations occur, long-term forecasts indicate continued upward pressure due to energy transition and infrastructure costs.
