In 2021, BeOptimized invested in 17 solar panels, with a total installed power of 5780 Wp. The expected annual energy production is around 5 MWh. With this production, BeOptimized will generate more energy than it consumes, and the surplus will be sent to the grid, where others will consume this 100% green energy. In parallel, BeOptimized replaced its diesel car with a 100% electric car, directly connected to the solar panels. These investments complement previous improvements made to the office, including double-glazed windows, roof insulation, automatic Velux shutters, a gas condensing boiler, electric reversible climate control, and real-time electricity consumption monitoring.
