Solar panel battery storage is a key component of your solar energy system. It captures any electricity that your panels generate throughout the day and stores it for use at peak times when electricity usage spikes.

Lithium-ion batteries are preferred for this application due to their high DoD and long lifespan. The most important factor is ensuring that the size of your storage system is properly sized to match your solar panels.

Reduced Energy Bills

With solar battery storage, homeowners can power their homes with clean energy all day and night. This will drastically reduce their reliance on the electric grid and energy companies, which charge expensive rates.

Solar + battery storage enables homeowners to make use of time of use rate plans, which can significantly lower utility bills. Unlike solar panels alone, which are not able to generate enough power to meet demand at peak times of the day, home battery storage will allow homeowners to store electricity and use it later when electricity prices are highest.

In addition to net metering, many states and cities offer additional incentive programs to encourage solar + battery adoption. These typically stack with the federal incentive, increasing the potential for savings even further. However, the size of your home energy system and how you choose to use your battery will have a huge impact on your overall cost of ownership.

More Energy Self-Sufficiency

Solar panel battery storage offers homeowners a way to fully maximize their solar energy systems. By assessing energy needs, right-sizing components, integrating smart energy management systems and staying updated on utility policies, homeowners can make sure their solar + battery systems perform at their best.

During cloudy periods and at nighttime, batteries can discharge power they've stored from sun-generated electricity to offset energy consumption. This further reduces dependence on the grid and helps homeowners achieve energy independence.

Many states and utilities have time-of-use (TOU) rates that increase electricity costs during peak demand hours. By using battery storage during these times, homeowners can avoid paying higher prices and thereby save even more on their electricity bills.

A battery system can also provide backup power for critical appliances during a power outage**. This further increases energy self-sufficiency and can offer protection against future power utility rate hikes. Embracing solar energy complemented by battery storage contributes to a greener environment, reduces carbon emissions and creates a more resilient energy ecosystem.

Increased Home Value

Many of us know that solar panels add to the value of a home. However, some may not be aware that a solar battery can further increase the value of a solar energy system.

A battery takes up the excess power generated by solar panels so it doesn’t go to waste. It can then supply power at night, on cloudy days or when the sun is not out. This helps to reduce a building’s reliance on retail electricity.

Solar energy is becoming increasingly popular in places with high electricity rates. Solar panel battery storage can increase the value of a solar system in these areas because it can help to offset high energy costs and save money over time.

A recent study by Zillow found that homes with solar sold for 4.1% more than comparable homes without. This is in addition to a separate study by Lawrence Berkeley National Laboratory that finds that for every $1 saved on utility bills, property values increase by $20.

Reduced Utility Rates

In addition to reducing your dependence on fossil fuels, solar energy provides financial benefits for homeowners. Solar battery storage allows you to reduce the amount of electricity you buy from the utility, reducing your electricity bills.

Adding a solar battery to your home can help you save money if your utility uses time-of-use rates or demand charges, which vary by region and by utility company. These rates make power more expensive during high demand times, like in the evenings, as utilities attempt to encourage consumers to use less power during peak hours.

With energy storage, your solar panels can produce energy during these peak periods and store it for later use, avoiding costly grid electricity. This can reduce your electricity bill by up to 30% or more, depending on your energy consumption and system configuration.
