A quick look at batteryless facility power.
Learn how indoor light collection and batteryless storage can power restroom dispensers without grid draw or battery swaps.
Indoor Photovoltaic Energy Harvesting
Your lights are already paying for your dispensers.
BrightHarvest harvests photovoltaic energy straight from your ceiling fixtures — stored batteryless — and delivers free power to every paper towel, soap, and hand sanitizer dispenser in your building. Zero grid draw. No battery swaps. Ever.

View detailsHow It Works
Light in. Free power out.
A closed loop that lives entirely inside your building's existing infrastructure — no rooftop panels, no new wiring runs.
1
PV collectors mount to existing fixtures
Slim indoor photovoltaic collectors clip onto your ceiling fixtures. No new lamps, no structural work — just a 15-minute per-fixture installation.
2
Energy stored in batteryless capacitors
Supercapacitors don't have a fixed “replacement age” the way batteries do — they're rated in charge cycles, not years. BrightHarvest's energy-storage bank is designed for hundreds of thousands of cycles. At a typical daily charge/discharge in a restroom dispenser, that translates to well over a decade of continuous use — realistically closer to the lifespan of the dispenser fixture itself, not something facilities would plan around replacing.
3
Dispensers run 100% off harvested light
Your paper towel, soap, and hand sanitizer dispensers draw from stored light energy — quietly, continuously, for free.
ROI Impact
The numbers that matter to facilities managers.
Every building we retrofit gets a custom energy audit before we start. The data below reflects real-world commercial deployments.
