These details allow Sentinel to model your system's full potential — what it currently does, what it's leaving behind, and what it could do with intelligent optimisation.

Did you know? The average solar and battery system without intelligent management leaves an estimated £400–£900 of potential value unrealised every year.

Your energy profile

These details allow Sentinel to model how your system interacts with your tariff and household rhythm — the foundation of intelligent optimisation.

Why this matters Intelligent systems don't just generate energy — they time it. The right charge and dispatch decisions, made automatically, can be worth hundreds of pounds per year. Your tariff type and usage pattern are at the heart of this.
