Photovoltaic Windows Heat Water in a Bucharest Apartment for Two Years
Reported byCleanTechnica ↗·Sourced by Goodlede
A two-year real-world pilot in Bucharest demonstrates semi-transparent photovoltaic windows supplying domestic hot water directly in DC without batteries or grid inverters, using the water heater itself as thermal storage for a household of four.
This is a single-site pilot; broader deployment and cost-effectiveness at scale remain to be demonstrated.
