Solar and battery price guide.

Start with what you already pay

Take an average $700 quarterly energy bill. That is about $2800 a year, $14,000 over 5 years, and $28,000 over 10 years before price hikes are considered.

That baseline alone already shows why many homeowners now see solar and battery as a practical long-term decision rather than a niche upgrade.

Use conservative power-price assumptions

Some retailers and installers use 10% yearly electricity price hikes in ROI models. We prefer to think in a more conservative 5% yearly rise.

At 5% yearly increases, that same $700 quarterly bill becomes roughly $15,475 over 5 years and $35,218 over 10 years.

At 10%, the 10-year figure pushes much higher again, which is why assumptions matter so much.

Typical payback ranges now make sense for many homes

For a solar and battery system, a frequent payback period is around 5-7 years depending on system size, usage, tariff conditions, and final install cost.

That does not make every system identical, but it does explain why more households now see the numbers making sense for the first time.

• • $700 quarterly bill = about $2800 per year
• • 5% yearly rise = about $15,475 over 5 years
• • 5% yearly rise = about $35,218 over 10 years
• • Typical solar-plus-battery payback = roughly 5-7 years
