Store summer.
Use it in winter.
Abundant iron. Reusable carriers.
A new way to move solar energy
across seasons.
Reusable iron energy carrier
Solar has
a timing problem.
Daily batteries are brilliant at moving energy from noon to night. Seasonal storage asks a different question: how do you move summer electricity across months?
Jun / Summer surplusEnergy available now. A reason to store it for later.
Illustrative normalized profiles. Not measured household data or a performance forecast.
The cheapest kWh is often produced
months before it is needed.
One home.
Three timescales.
Solar generates. Lithium buffers.
Fairlight is developing the seasonal layer—designed to work beside the systems you already know.
Preserve summer energy in reusable iron carriers for later use.
Fairlight’s seasonal operating window is a development objective.
Architectural concept visualizationEnergy becomes
a physical object.
Built to be handled, serviced, stacked and exchanged. A standardized frame holds replaceable stamped iron plates.
One stamped sheet.
Four jobs.
Manufacturing should look more like stamping a heat exchanger than building a battery cell.
Distribute.
Channels guide electrolyte across the plate.
Expose.
Formed surfaces make iron accessible.
Drain.
Gravity carries bulk liquid to an open outlet.
Dewet.
Vibration is explored to help release pinned droplets.
Charge it wet.
Store it dry.
Shared machinery does the active work. Preserved carriers wait in a passive rack. Explore the proposed process, one step at a time.
Charge.
The picker docks a carrier. Electrolyte enters the plate channels for active processing.
A season later.
A place away.
Electricity no longer has to stay where it was generated. A common carrier could make seasonal energy lendable, leasable and transportable.
Commercial rooftop
Summer solar production near a source of surplus.
A proposed operating model. Fairlight Exchange is not yet a trading or transport service.
New energy.
Familiar logistics.
Eight 400 × 300 mm footprints per layer. A common envelope designed around infrastructure that already exists.
Geometric illustration only. Stack height, packaging, pallet load and energy capacity require validation.
The cassette should
outlive the chemistry.
Fairlight intends to standardize the interfaces while allowing plate materials, coatings and process recipes to improve.
Define the interface.
Illustrative long-term roadmap, not launch dates or committed product revisions.
Every plate
has a history.
No powered tag required. A permanent optical identifier is designed to link each plate and cassette to signed lifecycle records.

Permanent optical identity is intended to link signed lifecycle events without a powered tag. Sample identity and events above are demonstrations.
Small enough to handle.
Big enough to rethink.
Designed in Switzerland.
Built for everywhere.
Seasonal storage should use materials and manufacturing processes available almost anywhere.
Founded by Daniel Alexander Kunz, Fairlight is developing a physical standard for moving summer energy into winter.
