Volume-based pricing and capacity reservation structured across multiple projects, negotiated once instead of purchase order by purchase order.
Talk to our teamStructure long-term supply agreements with volume pricing and capacity reservation across multiple solar projects. LTA services on Sunhub.
Volume-based pricing negotiates once against a buyer's projected pipeline instead of being renegotiated on every individual purchase order, which matters most for a distributor or EPC with predictable, recurring demand.
Reserved capacity with a supplier protects a buyer's allocation during a seasonal or policy-driven demand surge, the moments when spot-market buyers get pushed to the back of the queue.
Agreement terms get built around a buyer's actual projected volume and timeline, not a generic annual contract that doesn't reflect how the pipeline actually moves.
Volume pricing locks in against the pipeline instead of resetting deal by deal.
Reserved capacity holds a buyer's position when spot-market supply gets tight.
An LTA locks in volume-based pricing and reserved capacity across a pipeline of projects, so you are not renegotiating price or fighting for allocation on every individual purchase order. A standard PO covers one order at the price and availability of that moment, with no forward commitment either way. The LTA trades one-off flexibility for pricing stability and supply certainty over time.
There is no fixed threshold, but LTAs make sense when a buyer has enough committed or forecast volume across a project pipeline that locking price and reserving capacity outweighs buying spot. The stronger and more visible the pipeline, the more leverage there is to structure favorable terms. Sunhub structures agreements around real pipeline visibility rather than a single arbitrary volume cutoff.
Yes, reserving capacity ahead of demand is a core reason to sign an LTA, since it protects allocation during a supply crunch when spot buyers get squeezed on both price and availability. The agreement commits the supplier to hold production against your forecast so a demand spike doesn't leave your projects short. That forward reservation is exactly what a purchase-order-by-purchase-order approach can't guarantee.
