Peter’s Story

Peter had been noticing his electricity bills climbing year after year. Between running a busy household and wanting to keep everything electric — from heating and cooling to the pool and everyday appliances — his annual energy costs were becoming hard to ignore. He wanted a long-term solution that would reduce his dependence on the grid, lower his bills, and make his home more sustainable.

That’s when Peter reached out to Tech Solar Battery. After our team visited his home and conducted a full site assessment, we designed a custom solar and battery system tailored to his energy use and roof layout.

The final installation included a 14.96 kW JA Solar DeepBlue 4.0 solar array paired with a 16.12 kWh Sigenergy SigenStor-10S-16 battery. This setup not only maximised Peter’s solar generation but also allowed him to store excess energy during the day and use it in the evening — when power from the grid is most expensive.

Since the system went live, Peter’s home has been producing an average of 17,805 kWh per year, covering the majority of his electricity needs. His annual bill has dropped to just $245, showing exactly how solar panels work with your electric bill to turn energy costs into long-term savings.

With a 383.3% ROI, a 4.66-year discounted payback period, and a net present value of $48,618.57, Peter’s investment is paying off faster than expected — and the system is already generating returns.
