Freight Class for Solar Panels
Solar panels typically ship at freight class 92.5 to 150 — flat, palletized, and moderately dense.
What is the freight class for solar panels?
Framed panels palletized in stacks have reasonable density, keeping the class moderate. Fragility (glass) and large dimensions push some shipments higher. Full, banded pallets rate lower than loose or oversized loads.
Because freight class is density-driven, there isn’t a single fixed number for solar panels — class 92.5–150 is the common range. Run your actual dimensions and weight below to pin it down.
Standardized flat modules — dense, but glass
Solar panels are unusually consistent freight because PV modules are standardized: a pallet of framed panels stacked and banded has predictable, moderate density, rating class 92.5 to 150. Unlike most large flat goods, panels aren't mostly air — a module is glass, silicon cells, an aluminum frame and a backsheet, so a full pallet of them carries real weight and rates better than its size suggests. The freight profile is set less by density guesswork than by how many modules stack on the pallet and how well they're protected.
The two things that lift the class are fragility and size. Panels are glass-faced and crack or micro-fracture under point loads and flexing, so they need edge protection, corner blocks and firm banding — protection that's essential and adds some cube. And large-format or bifacial modules run big, pushing toward the higher end of the range. Inverters, batteries and mounting hardware ship as their own distinct commodities and shouldn't be blended onto module pallets.
Solar Panels freight class: worked examples
Density is weight ÷ volume (cubic feet = L × W × H in inches ÷ 1,728). Here is how typical solar panels shipments measure out:
Palletized PV modules — class 100
Framed solar modules stacked and banded, 78" × 40" × 45", 800 lb.
78 × 40 × 45 = 140,400 in³ ÷ 1,728 = 81.25 ft³. Density = 800 lb ÷ 81.25 ft³.
9.8 lb/ft³ → inside 9–10.5 → class 100 — a full module pallet is denser than it looks.
Dense-packed module stack — class 92.5
Modules stacked tighter on the same footprint, 78" × 40" × 40", 800 lb.
78 × 40 × 40 = 124,800 in³ ÷ 1,728 = 72.2 ft³. Density = 800 lb ÷ 72.2 ft³.
11.1 lb/ft³ → class 92.5 — tighter stacking reaches the dense end.
Large-format modules, fewer per pallet — class 150
Big bifacial panels edge-protected, 78" × 40" × 50", 600 lb.
78 × 40 × 50 = 156,000 in³ ÷ 1,728 = 90.3 ft³. Density = 600 lb ÷ 90.3 ft³.
6.6 lb/ft³ → class 150 — large-format panels with more protection rate the top of the range.
Stack, band, and protect the glass
Panels ship stacked — often flat-stacked with layer protection, or on edge in A-frames for larger modules, the way glass resists load best. Either way, full, tightly-banded pallets with corner and edge protection give both the density and the damage prevention: a loosely-loaded or partial pallet measures worse and cracks more. Keep stacks to a height the bottom modules can bear without point-loading, and use protective separators between panels so faces can't rub.
Value and fragility ride alongside the class. A pallet of solar modules is worth a lot and cracks are a total loss per panel, so coverage and careful handling matter beyond the freight rate. Confirm the destination can handle large module pallets. Ship inverters and batteries separately (lithium storage batteries carry their own dangerous-goods rules — verify with your carrier). Run the actual module stack through the calculator; a well-built solar pallet rates better than its footprint suggests.

How freight class is calculated (density scale)
Freight class is set by density = weight (lb) ÷ volume (ft³). Higher density → lower class → typically lower cost. Volume here is L × W × H × quantity.
| Density (lb/ft³) | Class |
|---|---|
| 50+ | 50 |
| 35 – 50 | 55 |
| 30 – 35 | 60 |
| 22.5 – 30 | 65 |

Frequently asked questions
What freight class is solar panels?
Solar Panels typically ships at freight class 92.5–150. The exact class is set by density — weight divided by volume — so packaging and dimensions can move it within that range.
What affects the freight class of solar panels?
The main factors are palletized stack density, glass/fragility, panel size, banding and protection. Denser, tightly packed loads rate a lower class and cost less to ship.
How do I find the exact freight class for solar panels?
Measure your shipment and divide weight by volume to get density, then match it to the NMFC scale — the calculator above does this. Confirm the final class and NMFC item number with your carrier before booking.
What freight class are solar panels?
Palletized framed PV modules measure ~10–11 lb/ft³ → class 92.5–100; large-format or lightly-loaded pallets rate up to class 150. Panels are denser than their size suggests because they're glass, silicon and aluminum, not air.
How are solar panels shipped safely?
Stacked with layer or separator protection (or on edge in A-frames for large modules), full and tightly banded with corner and edge protection. Keep stacks to a height the bottom modules can bear, and separate panel faces so they can't rub and crack.
Do inverters and batteries ship with the panels?
Ship them separately — inverters, mounting hardware and batteries are distinct commodities with different densities, and lithium storage batteries carry their own dangerous-goods rules. Blending them onto module pallets complicates both the class and the handling.
