Solar has changed a lot in the last few years. Panels are more efficient, inverters are smarter, and battery storage is far more practical than it used to be. Add in ongoing energy price uncertainty and new government support, and 2026 is shaping up to be a particularly strong year to invest in solar, whether that is for a family home, a commercial premises, or a multi site business.
Below is a UK focused look at why solar makes sense right now, what has changed, and what to consider before you get started.
What is different about solar in 2026?
The conversation has moved on from “does solar work in the UK” to “how do we design a system that fits how you actually use energy”.
In 2026, the most effective solar setups often include:
- smarter inverters and better monitoring, so performance is easy to track and issues are spotted early
- better options for managing shading and complex roofs, so more properties are suitable than people assume
- battery storage that helps you use more of your own generation in the evening, rather than exporting it
Why solar makes sense for homes in 2026
1) Save on electricity bills by generating your own power?
When your panels generate electricity, your home uses that power first. That reduces how much you need to buy from the grid, which is where the biggest day to day savings usually come from.
2) 0% VAT still applies, but it is time limited
In Great Britain, the installation of certain energy saving materials, including solar PV, is zero rated for VAT until 31 March 2027, after which it is expected to revert to the reduced rate. This makes 2026 a useful window for anyone already considering solar.
3) Get paid for what you export with SEG
If you generate more electricity than you use, you can export the surplus and get paid via the Smart Export Guarantee (SEG). You need to sign up to a SEG tariff, it is not automatic, and rates vary by supplier, but it can improve overall returns for homes that regularly export. You can find out more about the Smart Export Guarantee (SEG) here.
4) Battery storage helps you use more of what you generate
For many households, the main challenge is timing, solar generates most during the day, but many homes use more electricity in the evening. A battery can store surplus daytime generation and supply it later, increasing self consumption and reducing grid imports.
Why solar makes sense for businesses in 2026
1) Strong fit for daytime operations
Many businesses consume electricity during daylight hours, offices, warehouses, workshops, retail, hospitality, and that aligns well with when solar generates. The more energy you use on site, the more value you typically get from your system.
2) Commercial solar supports compliance and procurement
Many businesses consume electricity during daylight hours, offices, warehouses, workshops, retail, hospitality, and that aligns well with when solar generates. The more energy you use on site, the more value you typically get from your system.
3) Tax and accounting support may be available, but the detail matters
Many UK businesses can claim capital allowances on plant and machinery, including solar, but the rules vary by business type and asset classification. Solar is commonly treated as special rate expenditure, and full expensing is not available for special rate assets, so this is an area to review with your accountant as part of the financial case.
The UK Warm Homes Plan in 2026
The UK government has launched the Warm Homes Plan, a long term programme designed to support home upgrades, including measures such as solar, batteries, heat pumps, and insulation, with targeted help for low income households and a broader offer for others. It is a bigger topic in its own right, and we will cover it properly in a separate guide, but it is another reason solar is firmly on the national agenda in 2026.
What to do before you book an installation
Solar performs best when the system is designed around your building and your usage. Before you commit, it is worth checking:
- roof condition, usable space, and shading across the year
- your electricity usage pattern, especially daytime versus evening
- whether battery storage makes sense now, or later
- inverter choice and monitoring quality
- export setup, metering, and SEG tariff options
- for businesses, how the installation will be phased, and how the financial case will be documented
2026 is a strong year to go solar
Between improving technology, time limited VAT relief, continued export tariffs, and new government focus on home upgrades, 2026 is a sensible moment to move from “thinking about solar” to “designing a system that fits”.
