How come the shipping cost is so high?
Why Are Domestic US Shipping Costs for Solar Products So High?
Even when shipping from our US-based warehouses, solar batteries may still incur higher freight costs than standard packages. Here’s why—and how we’re working to reduce your expenses:
- Heavy Weight & Large Size
A single solar battery (e.g., 10kWh lithium-ion) can weigh 100–150 lbs (45–68 kg) and require palletized shipping.
Carriers (FedEx Freight, UPS LTL, etc.) charge by weight and dimensions, often classifying batteries as “oversized freight.”
- Hazardous Materials (HAZMAT) Requirements
Lithium batteries are regulated by the DOT (Department of Transportation) and FMCSA for ground transport. This means:
Special handling: Certified HAZMAT carriers must be used.
Limited last-mile options: Many local couriers won’t handle heavy lithium batteries.
- Shipping Method & Zones
LTL (Less-Than-Truckload) Freight: Cheaper for bulk orders but slower (3–7 business days).
Expedited Trucking: Faster but costs 2–3x more (e.g., for urgent commercial projects).
Remote Areas: Deliveries to rural zones (e.g., Alaska, Hawaii, or mountainous regions) incur additional surcharges.
- How We’re Lowering Your Costs
Free Shipping Thresholds: Orders over $10,000 qualify for free LTL shipping (contiguous US).
Local Pickup Available: Save 100% on freight by collecting from our warehouses in [California].
Bulk Order Discounts: Combine batteries with solar panels/inverters to optimize pallet space.
Pro Tip: Provide your ZIP code during checkout for real-time freight quotes, or ask our team about regional promotions!
