Solar PV Panels from the Brands UK Installers Specify

We focus our range on manufacturers that deliver real performance on UK rooftops. Aiko panels use All Back Contact (ABC) cell technology, achieving some of the highest module efficiencies on the market. Bauer is a German-engineered brand with CrefoZert accreditation, 30-year workmanship warranties, and bifacial modules built for long-term commercial confidence. Osda offers competitively priced TOPCon solar panels up to 700W+ for installers who need strong output at a sharp wholesale price per watt. JA Solar's DeepBlue series is one of the most widely specified solar modules in the UK. REC brings Norwegian-designed heterojunction (HJT) technology through its Alpha Pure range, alongside the affordable TwinPeak series for residential projects. We also carry remaining Longi Hi-MO stock for installers with existing specifications to fulfil. Every solar panel we supply is MCS-certified and UKCA-marked.

Solar Modules for Every Project Size

Our catalogue covers wattages from around 300W through to 700W+, spanning monocrystalline PERC, N-type TOPCon, heterojunction (HJT), and ABC cell technologies. For domestic retrofits where roof space is tight, 400W to 440W solar PV panels in the 1722mm format are the most popular choice, with options from JA Solar, Bauer, and REC all in stock. Larger residential and light commercial solar projects typically call for 450W to 500W modules, where Aiko's high-efficiency panels and REC's Alpha Pure range both perform well. For commercial and industrial rooftops, our 580W to 700W+ large-format solar panels from Osda and JA Solar deliver maximum generation per square metre. We also supply lightweight solar panel options suited to modular buildings, flat roofs, and structures where load limits are a concern. Whatever the specification, we can match the right panel to the job.

Wholesale Prices and Trade Account Benefits

As a solar panel wholesaler, everything we do is built around the trade. When you open a DECO Group trade account, you get access to trade pricing across our full range, and the wholesale cost drops further on pallet and bulk quantities. If you want to buy solar panels direct at the best possible price per watt, purchasing by the pallet is always the most cost-effective route. We also provide volume-based quotes for larger commercial solar energy projects and multi-phase rollouts. Your dedicated account manager handles live stock checks, bespoke pricing, and can advise on panel compatibility with inverters and mounting equipment from across our product catalogue. There are no minimum order values, so you can purchase a single solar panel for a warranty swap or order in bulk for your next install.

Technical Support from People Who Understand the Install

Ordering solar panels is only part of the job. Our team can advise on string sizing, inverter compatibility, voltage architecture, and mounting configuration before you commit to an order. If you are pairing solar PV panels with a Fox ESS hybrid inverter, a Fox ESS battery system, or a Solis setup, we can confirm compatibility and flag any firmware or wiring considerations. We also stock the full range of solar energy equipment and accessories your installs need: DC and AC isolators, MC4 connectors and branch connectors, DC solar cable, generation meters, consumer unit labels, and roof mounting systems from Renusol, K2 Systems, and ESDEC. One solar panel supplier, one order, one delivery to site.

UK Stock, Next Day Dispatch, and Reliable Supply

Installation schedules depend on materials arriving when they should. We hold popular solar panel lines in UK stock for next day dispatch, and for larger or less common solar modules we confirm lead times at the point of quotation so you can plan your install calendar. Pallet deliveries go out on dedicated vehicles with tail lifts, and we arrange direct-to-site delivery for commercial solar power projects anywhere in the UK. Every order includes full tracking. If availability on a specific module changes, we let you know early enough to adjust your schedule or switch to an equivalent alternative. Whether you need to buy solar panels in the UK for a single residential job or you are sourcing solar panels wholesale for a commercial rollout, our distribution network is set up to keep your projects on track. Not all solar panel distributors offer this level of visibility, and it is something our trade customers regularly tell us makes a difference.
