Residential Solar Battery Benefits
Residential solar battery maximize self-consumption, allowing homeowners to minimize energy purchases from the grid at peak utility rates. This strategy is a great way to avoid expensive demand charges and take control of your energy costs.
Many states and utilities are offering rebates and incentives that make solar batteries even more affordable. When shopping for a solar battery, be sure to balance capacity and power rating to get the best value for your investment.
Reliability
One of the best indicators for solar battery lifespan is manufacturer warranty periods. Most reputable manufacturers offer warranties that guarantee a certain amount of energy throughput or cycles. For example, Enphase offers a 10-year warranty on its second-generation IQ batteries.
Choosing an appropriately sized system is also important. This will ensure the battery isn’t overworked, which can cause premature degradation. In addition, selecting the right battery chemistry is vital for longevity. Nickel-manganese-cobalt and lithium iron phosphate are popular options for residential applications. These chemistries are less risky than older headlines might suggest and are able to support deep discharges without damaging the battery.
Solar battery backup systems are a smart investment for homeowners that want to maximize the value of their solar energy systems. These batteries also benefit the larger community by reducing strain on the grid and preventing blackouts. Power outages are a nuisance for everyone and can be even more frustrating when your solar panels aren’t generating enough electricity to offset them.
Efficiency
In standard solar energy systems, homeowners rely on the grid for power whenever their panels aren’t producing enough energy. Solar batteries reduce this reliance by storing excess energy to use at night or during outages.
Batteries can also save money by reducing utility demand charges. These demand charges are based on peak usage times during the day, and battery storage can help homeowners avoid these expensive hours.
When evaluating home battery options, it’s important to consider the system’s round-trip efficiency and depth of discharge ratings. A good rule of thumb is to aim for a battery with an 80% depth of discharge rating or higher.
Additionally, homeowners who want to make the most of their solar and battery investment should take a close look at available local incentives for both products. A reputable solar installer will be able to offer recommendations based on your household’s energy needs and goals. They will also be able to provide quotes on the cost of the battery system, installation and labor.
Blackout Protection
Blackout protection is a solar battery’s most visible benefit. Grid-connected solar systems shut off automatically when the power goes out to protect lineworkers and prevent backfeed current from passing onto distribution lines, but batteries with backup capacity can stay active – providing electricity for essentials such as lighting and refrigerators.
The larger a battery’s storage capacity, the more appliances it can power during an outage. Batteries can also be configured to prioritise which systems to send power to in the event of a blackout, allowing you to keep your fridge running and lights on for longer than a standard solar-only system.
Solar batteries with backup power are ideal for homes in regions prone to frequent outages or natural disasters, and can help reduce reliance on energy from the grid in an age of rising energy prices and energy uncertainty. Speak to your trusted solar expert to find a solution that best suits your household’s needs.
Energy Savings
In addition to the security of off-grid power, solar batteries offer significant financial savings over time. These benefits include reduced reliance on the grid, and the ability to avoid peak demand charges. Solar battery systems are also highly scalable, allowing homeowners to increase their system’s capacity as energy needs change. In addition, many regions offer incentives or rebates for solar batteries, further enhancing the return on investment of these solutions.
When a solar system produces more electricity than the home consumes, this extra energy is often fed back into the grid. This generates net metering credits on the homeowner’s electricity bills at a value set by their local utility. Solar batteries allow homeowners to shift their biggest usage hours to the middle of the day or even into the evening to avoid expensive peak rates.
In addition, some utilities offer time-of-use rates, where the cost of electricity varies by hour, day and season. Solar batteries allow homeowners to store excess electricity for use during these high-cost periods, driving significant bill savings.
