Home Solar Battery Systems – Comparisons and Costs

Jan. 2024

Giant leaps in battery technology have created huge interest in going off the grid, storing excess solar energy to increase self-consumption and achieve energy independence. However, rapid advances in technology have led to some confusion about what is achievable and which battery systems are best for individual homes. The cost can also vary significantly depending on the energy storage capacity (measured in kilowatt hours) and the type of solar inverter required.

How Much Does A Home Battery System Cost

The cost of a home battery system depends on the battery size or capacity (measured in kilowatt hours (kWh)) and the brand of solar or hybrid inverter used. The cost of a typical home battery ranges from $4,000 for a small 4kWh battery to $15,000 or more for a large 12kWh battery, depending on the battery type, installation location, backup power requirements and the type of inverter used. Costs have been slowly falling, but not as quickly as many would like.

For example, a three-bedroom house uses about 20 kilowatt hours of electricity per day on average. However, some of this energy is used during the day and can be powered directly by solar energy alone. With this in mind, a mid-sized 10kWh battery is usually sufficient for overnight and overnight use. Every home is different and usage patterns can vary widely. For those who are more energy conscious and use efficient appliances, a smaller 5 kWh battery such as Pytes' E-BOX-48100R may be suitable and provide enough backup power to support lighting, computers and refrigerators and other required loads of basic equipment.


Basic Battery Cost Guide

Generally speaking, in Australia the cost of installing a battery system is assumed to be around $1000 per kWh, while in the US it is closer to $700 per kWh. For example, a fully installed battery with 13.5kWh storage capacity costs around $15,000. If you add in the additional cost of a compatible hybrid inverter and installation, that’s even more money. There may also be additional costs and switch upgrades, especially if dedicated circuits must be backed up during an outage. Battery location is also important. Some homes may require a special case or cover to help protect the battery from extreme weather and direct sunlight, which can cause overheating and shutdown. In many cases, the warranty may be void if the battery is not installed in a semi-protected location.

Solar And Battery Cost Calculator

When installing a home solar system, homeowners need to consider installation costs, additional components, and any applicable taxes. If you need tools to help you quickly estimate solar costs, use the Pytes System Calculator to estimate electricity usage (in kilowatt hours) based on the devices you plan to power.
