Where reels come from
Empty reels from solar projects
Empty cable reels from solar installations in Pennsylvania and South Jersey: rooftop arrays on warehouses, ground-mount projects on farmland, DC and medium-voltage cable reels and their reuse.
Solar on roofs and fields
Solar has spread across the region in two forms. On the roofs of the big warehouses and distribution centres along I-95, Route 130 and the Turnpike, and on schools, offices and homes, rooftop arrays turn flat roofs into generators. On open land, especially in South Jersey and the farmland of Chester, Bucks and Gloucester counties, ground-mount arrays fill fields with rows of panels. Both kinds use a lot of cable, and the reels they leave are a steady source of empties in the reel trade.
What solar projects use
- DC string and homerun cable carrying power from panels to inverters or combiner boxes. It is usually wound on mid-size wooden reels or plastic spools.
- AC collection cable from inverters to the point of connection.
- Medium-voltage cable on larger ground-mount projects, from the array to a transformer and the utility connection, on large wooden reels.
- Grounding wire on spools.
- Communications and monitoring cable on small spools.
Reels from rooftop jobs
Rooftop installers bring cable up by crane or hoist and send empties back down at the end. A warehouse roof job leaves a pile of mid-size reels and spools in a corner of the yard or a trailer. Warehouses have docks and forklifts, which makes these quick pickups. Tell us whether the reels are on the roof, in the yard or already in a trailer.
Reels from ground-mount projects
Ground-mount projects sit on open land with temporary roads, and their reels are often spread along the rows where the cable was pulled. Gathering them into one spot beside a firm access road before pickup saves a lot of time. Medium-voltage reels for the collection system and the interconnection are large and may be returnable; check for stencils and numbers.
Condition
Solar reels are usually in reasonable shape because the projects are short and the cable is pulled quickly. Problems come from reels left in fields through wet weather, or run over by equipment in the rows. Plastic spools of DC cable crack in the cold and fade in the sun; they go to plastic recycling.
Who reuses solar reels
Mid-size wooden reels from solar jobs are typical contractors' reels and go back into use for cable, rope and hose, or to makers for tables. Small spools go to gardeners and farms, which is a fitting end for reels from a project on farmland.
Recurring work
Installers who complete jobs every week, especially residential and commercial rooftop firms, produce a steady flow of spools and small reels at their warehouse. A recurring pickup keeps it clear.
Inside an array's wiring
A photovoltaic system has more cable types than most people expect. Panels connect in series strings with short leads and connectors; string or homerun cable, often sunlight-resistant PV wire, carries direct current to combiner boxes or straight to string inverters. Larger projects use central inverters fed by aluminium DC feeders, then step the inverter output up through pad-mounted transformers. Grounding runs bond every rack, module frame and enclosure. Weather stations, trackers and monitoring gear need control and communication cable. Battery storage, increasingly paired with solar, adds heavy DC and AC conductors between battery cabinets, inverters and switchgear. Each of those cable types ships on a reel suited to its weight and stiffness, so a single project produces several distinct sizes.
Trackers, trenches and directional bores
Ground-mount arrays on single-axis trackers rotate panels to follow the sun, with small motors and controllers on each row. Cable to those rows is usually buried in trenches or pulled through conduit laid by directional boring under roads, wetlands and drainage ditches. Trenching crews unspool reels along the trench from trailers, leaving empties at the end of each run. Ask the crew to stack them beside the access road as they finish rather than leaving them out in the field.
Community and commercial programmes
New Jersey and Pennsylvania both encourage solar through state programmes, and many schools, warehouses, farms and municipal buildings now host arrays. Developers and installers that build several projects a year, each with similar wiring, generate predictable reel volumes. That suits a standing arrangement: we learn the typical sizes and arrive with the right truck.
Repowering and repairs
Older arrays are being repaired or repowered with newer modules and inverters. Crews remove old cable and replace it, and the removed copper and aluminium go to metal recyclers. The new cable arrives on reels, which we collect afterwards.
Farmland, sheep and pollinators
Ground-mount projects on farmland often keep the land in agricultural use, with sheep grazing between rows or pollinator meadows planted underneath. Farmers who host arrays sometimes ask for reels for fencing, hoses and gates. Hosting landowners can request spools at the same time we collect.
Electric vehicle carports
Solar canopies over car parks combine steel structures, panels, lighting and chargers. Builders pour footings, erect columns, then pull feeders underground to each charger pedestal. Those jobs leave timber drums, plastic spools and offcuts of conduit at the edge of the lot, often in a corner nobody visits until the asphalt is restriped.
Questions
Do you collect from rooftops?
We collect from ground level. Bring reels down with the job's own hoist or crane before pickup.
Do you take damaged solar panels or racking?
No. Reels, spools and lagging only.
