The UK solar market now has one more European manufacturer to choose from. SoliTek, a Lithuanian panel producer, has signed a distribution deal to bring its modules into British homes. That is one more name on an installer’s price list – and for homeowners weighing a rooftop array, every extra option matters when the average 4 kW system still runs north of £6,000.
As reported by Solar Power Portal, SoliTek will supply its glass-glass bifacial panels through a UK distributor, with availability expected by mid-2025. The company claims efficiencies of up to 22.6%, putting it in the same bracket as market leaders like Longi and JinkoSolar. But for a household in Milton Keynes or Manchester, the question is not just efficiency – it is whether this new entrant will nudge prices down.
Who qualifies – and who doesn’t
Every homeowner considering solar should treat a new manufacturer’s arrival as a signal to shop around. More supply chains mean installers have more use in procurement, and that can trickle down to the quote you sign. But the effect is rarely instant. SoliTek’s panels must first clear installer stockists and be tested by the UK’s Microgeneration Certification Scheme (MCS) – a prerequisite for most government incentives.
The real winners here are homeowners who can wait. If you are replacing a roof in 2026 or planning a full retrofit, the extra competition may deliver a 5–10% reduction on panel cost by then. Those who need a system this summer will see little immediate change – labour, scaffolding, inverter, and battery storage still account for 60–70% of the total bill.
What it costs a typical 3-bed semi
A standard 4 kWp array with 10 panels currently lands between £6,000 and £8,000, according to Energy Saving Trust estimates. The panel hardware itself is roughly £1,200–£2,000 of that. If SoliTek’s entry shaves 10% off panel costs, the saving is about £120–£200 – welcome, but not a game-changer for a household budget.
What matters more is the panel’s performance over 25 years. SoliTek’s glass-glass construction typically offers better durability and lower degradation rates than traditional glass-backsheet panels. That could mean 88–90% of original output after 25 years, versus 80–85% for cheaper models. Over a system’s lifetime, that extra yield might be worth £400–£600 in avoided grid purchases, assuming current electricity prices.
The catch – installer availability and certification
But… a new brand means nothing if your local installer does not stock it. SoliTek’s distribution partner has not yet announced which regions will get first access. Homeowners in Scotland or the South West may find the panels listed but not physically available for months. The MCS certification process can take 6–12 weeks once the panels land in UK warehouses.
There is also the question of warranty support. SoliTek offers a 30-year linear performance warranty and a 15-year product warranty, which is standard for Tier-1 European manufacturers. But if the company ever pulls out of the UK market – as some smaller brands have – homeowners could be left chasing a cross-border warranty claim. That risk is lower with SoliTek, which has been in business since 2013 and operates its own factory in Lithuania, but it is not zero.
What happens next
Homeowners serious about solar should use this news as a prompt to get three quotes from MCS-certified installers. Ask each one which panel brands they offer and whether they plan to stock SoliTek. Compare the cost per watt, the degradation warranty, and the installer’s own workmanship guarantee. The best time to buy is when you have three competitive quotes in hand – not when a new brand appears in a press release.
If you are not ready to install this year, bookmark this development. By early 2026, SoliTek panels should be on UK soil and priced competitively. That is the moment to re-request quotes and see if the market has shifted in your favour.
Frequently Asked Questions
Not immediately. New entrants need time to build installer stock and MCS certification. Over the next 12–18 months, increased competition may shave 5–10% off panel costs, but the total system price depends heavily on labour, scaffolding, inverter, and battery costs.
Not inherently. Efficiency and durability vary by model, not origin. SoliTek's glass-glass bifacial panels offer strong degradation performance (0.4% per year), but Chinese Tier-1 brands like Longi and JinkoSolar match or exceed that. The key is comparing the specific datasheet and warranty, not the flag on the box.
