Solar for Your Industry
A gym runs air conditioning, lighting and equipment from morning to night, and its busiest hours are in the evening, inside the grid’s peak window, when solar has faded. Solar covers the daytime share; managing the evening is where the rest of the savings are. Xtreme Gym runs 45 kW across 3 sites, monitored by Wattey SPC (as of 5 November 2026).

A gym fills up after work, in the evening, exactly when solar output fades and the grid’s peak window begins (for LESCO, 5–9 PM in winter and 7–11 PM in summer). Cooling and equipment at full use in peak hours is the most expensive load a gym has.
A gym chain with several branches has several small systems. Wattey SPC monitors all of them on one screen, string by string; Xtreme Gym’s 3 sites are monitored this way.
Yes for the daytime load: cooling and lighting run while the sun is up. The busy evening still runs on the grid in peak hours, so measuring and managing that window adds to the savings.
Yes. Wattey SPC shows every branch and inverter on one screen. Xtreme Gym’s 3 sites are monitored this way.
