As energy costs rise and sustainability becomes increasingly important, many Kiwi homeowners are looking closely at the option of home battery storage systems. These systems store energy from your solar panels or the grid for later use, reducing your reliance on traditional energy sources and ideally, slashing that monthly power bill. A home battery system is not necessarily going to be a cure-all for your electricity woes however, it’s very much dependent on the needs of your household, so let’s take a closer look at the pros and cons:
Pros
Peak Shaving – By storing excess energy generated by solar panels or from the grid during off-peak hours, you can rely less on your utility company and avoid higher energy costs during peak times. Christchurch and Rolleston residents can benefit significantly from this, as it helps manage local power costs more effectively.
Peak shaving is a strategic way to save money on your electricity bills. It works by taking advantage of the difference in electricity costs during peak and off-peak hours. During off-peak hours, when electricity demand is low, and rates are cheaper, you can charge a home battery system with electricity from the grid. This is especially useful in areas like Christchurch and Rolleston where energy prices fluctuate.
Alternatively, you can schedule to discharge your battery system during peak hours when the export buy back rate is higher. Companies such as Ecotricity are now offering a 51cent per KWH buy back rate for exported Solar during peak times. Lincoln Flexibility Project (ecotricity.co.nz).
Cost savings over time – By using stored energy during peak hours when electricity rates are higher, you can reduce your overall energy costs. While the initial investment in a battery storage system can be high, it often pays off in the long run. Some studies suggest savings of 10-20% on your energy bill, depending on your usage patterns and energy rates.
Emergency backup power – Home battery systems can provide backup power during outages. This feature is especially valuable in areas prone to frequent power disruptions or for those who rely on medical equipment that requires a constant power supply.
Environmental benefits – when used in conjunction with solar panels, home battery systems can help reduce your carbon footprint. This contributes to a more sustainable lifestyle and supports the transition to renewable energy sources.
Increased property value – Homes equipped with the latest energy storage systems may have a higher market value, as a new generation of eco-savvy buyers seek out homes that come equipped with these kinds of features.
Cons
A high initial cost – The upfront cost of purchasing and installing a home battery system can be significant, ranging anywhere from $5,000 to $15,000 depending on the size and type of system you require. For Christchurch and Rolleston homeowners, it’s important to weigh this cost against long-term savings.
Maintenance and lifespan – your batteries do require maintenance and have a finite lifespan, typically ranging from 5 to 15 years. Over time, their efficiency can decrease, but the good news is, the batteries we use here at Juice Electrical, in partnership with Infinite Energy, have a guaranteed minimum lifespan of ten years.
What sort of household will get the most benefit from battery storage?
Solar Panels – If you already have solar panels, a battery system allows you to store excess energy and use it when the sun isn’t shining.
High Energy Bills – Households with high energy consumption can benefit the most from the cost-saving potential of battery storage.
Frequent Power Outages – For those in more rural areas around Rolleston, or in Christchurch suburbs that experience frequent power outages, a battery system provides reliable backup power.
Conversely, if you have low energy usage, minimal peak-hour consumption, or live in an area with low solar potential, the benefits of a battery storage system may not outweigh the costs.
We understand there’s a lot to consider, so we encourage Christchurch and Rolleston residents to get in touch with the team at Juice Electrical today about whether an energy storage system is the right solution for you and your family. Greg has been working with home energy storage technology from the very beginning, and he really does know his stuff. He will also be honest with you if he thinks that the costs will outweigh the benefits, so email at greg@juiceelectrical.co.nz and get the juice on a home battery system today.
