Battery storage represents a monumental leap forward for residential solar owners, unlocking new energy management and sustainability possibilities. To truly grasp the intricacies of battery storage, homeowners can find it helpful to draw parallels with a familiar everyday item: their cell phone battery.

To begin, consider your home battery storage system like a brand new cell phone, charged to its total 100% capacity. Like your phone, the home battery undergoes cycles of charging and discharging, aptly referred to as “charge cycles.” Each time your phone’s battery runs low and needs recharging, it completes a cycle, and over time, these cycles gradually reduce the battery’s overall capacity.
For instance, a typical lithium-ion cell phone battery has a 2-3 years lifespan, encompassing 300-500 charge cycles as specified by manufacturers. After this period, the battery’s capacity will decrease by approximately 20%. By examining the “depth of discharge” (the percentage of energy drained from the battery) alongside the number of discharge cycles, one can observe how the battery’s overall capacity declines with each cycle.
In essence, understanding home battery storage becomes more accessible when comparing it to the familiar workings of a cell phone battery. By recognizing the similarities in cycles, capacity, and lifespan, homeowners can better appreciate the nuances of solar energy storage, empowering them to make more informed decisions about their energy needs and management.
Comparing your home storage equipment warranty to your phone battery warranty
A manufacturer’s warranty is a promise made by the manufacturer or seller of a phone to repair or replace the phone if it develops certain problems within a specified period of time after purchase. The warranty terms, including what is covered and for how long, vary depending on the manufacturer and the specific phone model.
With your home battery storage system, your equipment will come with a standard manufacturer’s warranty to protect you from any faulty equipment or issues that arise within the first few years. During the time of installation, you can also have it covered under a Solar Insure 20-Year Battery Monitoring and Warranty. Having this additional protection can help with battery repairs, parts and labor, as well as a complete replacement if your battery falls below 50% capacity in years 11-20.
In general, most battery storage manufacturers only cover the equipment for 10 years or above 70% capacity.
How often do battery storage systems need to be replaced on a residential solar system?
The lifespan of a residential solar system’s lithium-ion battery can vary depending on the specific battery technology, manufacturer, usage, and manufacturer specifications. Lithium-ion batteries used for solar energy storage generally have a lifespan of around 10 to 15 years. Some high-quality batteries might last even longer, up to 20 years.
Battery degradation is a natural process that occurs over time as the battery goes through charge and discharge cycles. As the battery degrades, its storage capacity and performance will decline.
To maximize the lifespan of your battery storage system, it’s essential to follow the manufacturer’s recommendations for usage, specifications, and temperature management. Regular inspections and monitoring can also help to identify any issues early on and ensure the system operates efficiently.
If a battery storage system is used in a way that is outside of its design specifications, it may need to be replaced sooner than expected. In general, it is a good idea to plan for the eventual replacement of a battery storage system as part of the overall lifecycle management of the system.
How can offering battery storage help solar installation companies grow?
Offering battery storage as a part of a solar installation package, especially now as batteries are financially incentivized, can help solar companies grow in several ways:
Increased customer satisfaction: Many customers are interested in having a battery storage system as part of their solar installation so that they can use the stored solar energy when the sun is not shining. By offering battery storage, solar companies can provide a more comprehensive and attractive package to their customers.
Increased revenue: Installing a battery storage system can be a significant upsell for solar companies, as it can add thousands of dollars to the total cost of a solar installation. This can lead to increased revenue for the company.
Enhanced reputation: By offering cutting-edge technology like battery storage, solar companies can enhance their reputation as forward-thinking and innovative companies, which can lead to increased customer loyalty and more referrals.
Diversified service offering: Offering battery storage can help solar companies diversify their service offerings and reduce their reliance on the solar installation market, which can be subject to fluctuations due to factors like weather and policy changes.
Ability to participate in new markets: Some markets, such as those with high electricity prices or those with incentives for energy storage, maybe more attractive for solar companies that offer battery storage.
What are the benefits for homeowners of adding battery storage to their solar installation?
Adding a battery storage system to your solar system along with a Solar Insure 20-year monitoring and warranty can provide several benefits, including:
Energy independence and reliability: A battery allows you to store excess solar energy for use during peak demand periods, at night, or during power outages. This enhances your energy independence and provides a reliable source of power.
Cost savings: By using stored solar energy during peak demand times, you can avoid higher electricity rates and reduce your utility bills. In some cases, you might be eligible for time-of-use pricing or net metering programs that provide additional cost savings.
Financial incentives: As of January 2023, homeowners can receive an uncapped 30% tax credit for a battery storage installation. The average tax credit will be around $5,400, depending on the size of the system.
Increased property value: According to NREL, your property value increases by $20 for every $1 you save on energy bills. Homes with solar storage systems are often more attractive to potential buyers, as they offer energy independence, cost savings, and environmental benefits. This can increase the property’s value and make it easier to sell in the future.
Peace of mind with warranty coverage: A 20-year monitoring and warranty from Solar Insure offer long-term protection for your battery storage system. This coverage ensures that any issues with the system are promptly addressed, minimizing downtime and maintaining optimal performance.
