With the growing interest in solar energy, homeowners are increasingly looking for ways to maximize their energy efficiency. However, a recent FranklinWH survey of 1,000 U.S. adults revealed that more than half (56%) of consumers will admit they aren’t familiar with the benefits of residential energy storage. 

Many still hold misconceptions about home battery systems. In this article, we’ll clarify four key misunderstandings surrounding home battery storage that solar installers need to address to help homeowners make informed choices.

Understanding Home Energy Storage

What is Home Energy Storage?

Home energy storage systems (HESS) allow homeowners to store excess energy generated by solar panels or sourced from the grid for later use. This stored energy can support power needs during peak hours, outages, or when solar generation is low. Despite their clear benefits, many homeowners hesitate to invest in these systems due to misinformation.

The Importance of Accurate Information

Recent surveys indicate that more than half of consumers are unfamiliar with the advantages of residential energy storage, which can hinder their ability to make well-informed choices about their energy systems. Education is essential for helping homeowners understand these technologies’ full potential and benefits.

Misconception 1: Solar Energy Alone is Sufficient

Thinking Solar Is Enough

A common belief among homeowners is that having a solar panel system eliminates the need for a home battery. This perspective overlooks several critical factors:

• Daytime Energy Generation: Solar panels only produce electricity during the day, while many homeowners consume the most energy in the evening.

• Utility Interdependence: Those with grid-tied solar systems send excess energy back to the grid. This can be problematic during power outages, as grid-tied systems typically shut down.

Why Batteries Enhance Solar Efficiency

1. Maximizing Solar Use: Batteries store excess energy generated during the day for nighttime use, effectively maximizing energy efficiency.

2. Energy Independence: By utilizing a battery storage system, homeowners can access solar energy even during grid outages, leading to enhanced energy security.

Misconception 2: Home Battery Storage Systems Are Only for Backup

Underestimating Their Capabilities

Many homeowners mistakenly assume that the sole purpose of home battery systems is to provide backup power during outages. While this is a valuable function, modern battery systems offer a range of additional benefits:

• Smart Management Features: Advanced energy storage technologies can intelligently manage electricity usage, providing both backup and Time-of-Use (TOU) capabilities.

• Prioritizing Energy Needs: Systems equipped with load management functions can prioritize essential appliances, ensuring that critical devices remain powered during an outage.

Multiple Functions of Energy Storage Systems

1. Emergency Power: Batteries allow homeowners to retain essential power during blackouts.

2. Energy Optimization: These systems help balance energy production and consumption for overall efficiency.

3. Environmentally Friendly Solutions: They support sustainable living by reducing reliance on fossil fuels.

Misconception 3: Investing in a Battery System Isn’t Worth It

Skepticism Around Return on Investment

A frequently cited concern is whether a battery energy storage system (BESS) is truly worth the investment. Homeowners may perceive these systems as expensive without understanding their financial benefits.

• Government Grants Pay For All Solar Equipment & Batteries: The Inflation Reduction Act offers tax credits to homeowners looking to purchase their own solar systems, as well as grants to those who wish to reduce their energy costs through solar and battery storage without the need for cash payments, leases, or loans.

• Declining Battery Prices: The cost of battery storage has dropped significantly in recent years, making them much more economical.

• Managing Demand Charges: BESS effectively handles peak load charges, helping homeowners minimize costs.

• Time-of-Use Savings: Battery systems enable homeowners to store energy when it’s cheaper and use it when costs are higher, allowing for significant savings.
  

Understanding Financial Benefits

1. Avoiding High Fees: By managing peak energy use, homeowners can evade hefty charges imposed by utility companies.

2. Effective Energy Use: Using stored energy during peak hours can drastically reduce electricity bills.

3. Increased Returns on Solar Investments: In certain regions, stored energy can be sold back to the grid at optimal prices, helping homeowners further recoup their investments.

Misconception 4: Battery Storage Systems Are Risky

Concerns About Safety

There are fears regarding lithium batteries, often stemming from their misuse in older technologies. However, advancements in battery technology have significantly increased safety standards.

• Safer Chemistry: Modern home batteries typically utilize Lithium-Iron Phosphate (LFP), which is much safer than older lithium-ion technologies.

• Enhanced Thermal Management: Contemporary systems are equipped to avert issues like thermal runaway, addressing significant safety concerns.

Understanding Modern Safety Standards

1. Robust Designs: Today’s battery systems often include built-in safety features that reduce risks significantly.

2. Stringent Regulations: Industry regulations ensure that battery systems meet rigorous safety standards, enhancing consumer trust.

The Power of Education: Empowering Consumers

Why Knowledge is Essential

Informing homeowners about these misconceptions can encourage greater adoption of home battery systems. With energy costs on the rise and growing concerns about reliability, understanding the real benefits of energy storage is imperative.
