Why Investing in a Battery System is a Bright Idea for Grid-Tied Solar Homeowners

When considering the integration of solar power into a home, particularly for those who are grid-tied, the question of the payback value of adding a battery system often arises. It's essential to clarify that the dynamics of payback are vastly different for off-grid solar setups, where there is no grid electricity for cost comparison. However, for homes still connected to the electrical grid, the benefits of solar are already evident—such as reduced electricity bills and a smaller carbon footprint. Yet, the advantages of pairing solar with a battery system can be even more diverse.

The Financial Perspective

Let's break down the numbers using a hypothetical scenario: Imagine you invest in a 20 kWh battery system for your solar-powered home. Factoring in typical usability and efficiency, you'd be able to tap into about 18 kWh of this battery daily.

Now, if there's a net benefit of 33 cents for every kWh, this translates to a daily saving or earning of $5.94. Annually, this accumulates to an impressive $2,168.10.

So, what about the return on investment? With a $14,000 battery system cost, the payback period based on these savings alone is approximately 6.46 years. And while that's a decent timeframe, there are also other advantages in the mix.

Value Beyond Numbers

While the direct savings are compelling, the true value of a battery system extends beyond just the calculative return on investment:

  • Property Appreciation: Homes equipped with solar and battery storage solutions can command a higher resale value. Thus, while you enjoy savings on your energy bills, you're also boosting the overall value of your home, making the payback in real estate terms nearly immediate.

  • Backup Power: Battery systems act as a safety net. In instances where the grid fails, you won't be left in the dark. Your battery system ensures that your home remains powered, safeguarding both convenience and security.

  • Time-of-Use (TOU) Pricing Benefits: Many utility companies have TOU pricing structures, charging more during peak hours and less during off-peak periods. With a battery, you can store energy when it's cheap and use it when rates are high, amplifying your savings.

  • Reduced Carbon Footprint: By optimizing the use of solar-generated energy stored in batteries, you are relying less on non-renewable energy sources. This leads to a significant reduction in your carbon footprint, making your household more eco-friendly.

  • Green Living: Beyond the tangible savings, there's a value in being an advocate for sustainable living. Having a solar battery setup not only aligns with environmental stewardship but also sets a precedent for green living in your community.

Harnessing the full potential of a solar battery system provides a comprehensive suite of benefits, ranging from financial gains to promoting a sustainable future.


Combining solar panels with a battery system elevates the benefits of green energy. Beyond the straightforward savings, it offers consistent power, even during outages. It's also a nod to future-proofing your home's value and sidestepping the anxiety of fluctuating energy prices. Integrating a battery with your solar arrangement? We see it as a thoughtfully calculated step in the right direction, it's just a smart move all around in our opinion.
