Solar payback in BCS: how to estimate yours

Payback is how long the system takes to pay for itself in saved CFE bills. In BCS, strong sun and high electricity rates — especially the DAC tariff — generally make payback favorable, but yours depends on your consumption, tariff, system cost, and whether you add batteries. Here's how to estimate it.

The basic math

Annual CFE savings compared to the system cost gives you the payback in years. It's a simple calculation, but every number depends on your situation, so we model it with your real data rather than quoting a generic figure.

What shortens payback in BCS

Being on the DAC tariff, high summer AC use, strong sun, and rising CFE rates all shorten payback. The more you pay per kWh today, the faster the system pays for itself.

What lengthens it

Adding batteries lengthens payback — you're buying resilience as well as savings — as does low consumption. We give you an estimated payback in your quote so the decision is based on real numbers, not assumptions.
