New & Used Solar, Wind & Storage Equipment For Sale

Commercial solar, wind and storage equipment covers the components used in renewable energy generation and battery storage installations. The category includes solar PV panels (mono and polycrystalline), solar inverters (string, hybrid, micro), solar PV mounting systems (roof and ground-mount), solar batteries (lithium iron phosphate, lithium-ion), battery inverters, battery chargers, wind turbines (on-grid, off-grid, off-shore) and ancillary equipment. UK installations operate under MCS (Microgeneration Certification Scheme) for accredited installers, G98/G99 grid connection rules from the Energy Networks Association and Building Regulations Part P for electrical work.

Why buy used solar, wind and storage equipment?

The renewable energy second-hand market is growing, and used equipment can offer significant value for the right project.

• Cost savings: used solar panels and inverters typically sell at 30-60% of new pricing, lowering project payback periods substantially.
• Immediate availability: popular new equipment can have lead times of weeks to months. Used stock is typically available immediately.
• Proven performance: modules and inverters with documented production history demonstrate real-world performance.
• Sustainability: reusing solar panels, inverters and batteries with remaining useful life avoids the embodied carbon of new manufacture.
• Suitable for many projects: used equipment works well for off-grid, secondary, agricultural and lower-priority installations where the latest efficiency isn’t critical.

Solar panels

Solar panels convert sunlight into electricity via photovoltaic cells. Modern modules range from 350W up to 700W+ per panel, with monocrystalline (higher efficiency) dominant for new builds and polycrystalline still available in second-hand stock. Common manufacturers include SunPower, JinkoSolar, Trina Solar, JA Solar, LG, Canadian Solar and REC.

Solar inverters

Solar inverters convert DC from solar panels into AC for grid or load use. String inverters dominate residential and commercial installations; microinverters and power optimisers suit shaded or complex roofs; hybrid inverters integrate battery storage. SMA, SolarEdge, Fronius, Growatt, Solis, Fox ESS and Huawei are dominant brands.

Solar batteries

Solar batteries store solar generation for evening use, off-grid operation or grid services. Lithium iron phosphate (LFP) dominates new installations for safety and cycle life. Tesla Powerwall, Pylontech, BYD, GivEnergy, Sonnen and SolarEdge Home Battery are common platforms.

Solar PV mounting systems

Solar PV mounting systems include rail systems, roof clamps, ballasted ground-mounts and tracker systems for utility-scale installations. Van der Valk, Schletter, K2 Systems and Renusol are common European brands. Choice depends on roof type (slate, tile, metal, EPDM, ground), wind zone and snow load.

Battery inverters and chargers

Battery inverters manage charge and discharge of battery banks and grid interaction. Battery chargers support off-grid and back-up systems where dedicated charging from solar, wind or grid is needed.

Wind turbines

Wind turbines come in three categories on the platform: on-grid (connected to the public grid for export), off-grid (standalone or hybrid systems with batteries) and off-shore (large-scale marine installations and components). Sub-100kW turbines suit farms, estates and rural commercial sites; multi-MW turbines serve utility-scale wind farms.

• Power rating and efficiency: for solar panels, modern monocrystalline modules deliver 20-23% efficiency. For inverters, 97%+ peak efficiency is now standard. Match capacity to your generation or storage target.
• Manufacturer warranty status: solar panels typically have 25-30 year power warranties; inverters 5-10 years standard; batteries 10 years/10,000 cycle warranties common. Used equipment may have warranty remaining if originally registered.
• Compatibility: verify panel-to-inverter compatibility (voltage, current windows), inverter-to-battery compatibility (DC voltage range, communication protocols) and grid connection compatibility (G98/G99).
• Certification and standards: MCS-listed equipment is required for accredited installations. CE marking, IEC standards (61215, 61730 for panels, 61727/62116 for inverters) confirm compliance.
• Battery chemistry and cycle life: lithium iron phosphate (LFP) typically delivers 6,000-10,000 cycles vs 3,000-5,000 for older NMC chemistries. Cycle life directly affects lifetime energy delivered.
• Grid connection requirements: G98 covers single-phase up to 16A, G99 covers larger or three-phase systems. DNO approval is required for any grid-connected generation or export.
• Installation considerations: factor in mounting compatibility with your roof or ground conditions, cable runs, isolation switches and any structural assessments needed.

• Commercial rooftop solar: warehouses, factories, schools, hospitals and offices using rooftop PV to offset daytime electricity demand and lower running costs.
• Solar farms and ground-mount: utility-scale solar PPAs, agrivoltaic projects and developer-led solar parks installing in volume.
• Self-consumption and battery storage: domestic and commercial users adding battery storage to maximise self-consumption and provide back-up.
• Off-grid and rural: farms, estates, mobile installations and remote properties using solar, wind and battery to reduce or eliminate grid dependency.
• Wind generation: farms, community schemes and developers operating sub-MW and multi-MW turbines for self-consumption or grid export.
• EV charging and load-shifting: businesses combining solar, storage and EV charging infrastructure to balance demand and minimise grid import.

The Commercial Trader features renewable energy listings from sellers across the UK and Europe. Use our location and distance filters to find equipment near you, supporting site collection and reducing logistics costs on bulk panel or battery orders.

Quality solar panels are designed for 25-30 years of operational life, with warranties guaranteeing typically 80-87% of original output at year 25. Inverters typically last 10-15 years, with one or two replacements over a panel’s life. Modern lithium iron phosphate (LFP) batteries are designed for 10-15 years and 6,000+ cycles. Wind turbines are designed for 20-25 year operational lives. Mounting systems and structural elements often outlast the electronics.

As we operate as a marketplace, any returns policy must be agreed directly with the seller before purchase. We strongly recommend pre-purchase inspection where possible, including verification of certification, condition and any remaining manufacturer warranty. New equipment from authorised distributors typically carries standard warranty terms; used equipment is usually sold as seen following inspection.
