🚨 2026 Auckland Market Update: > As of January 2026, Auckland homeowners are facing a new energy landscape. Following Vector’s 21% line charge increase and the ongoing phase-out of the “Low User” tariff, the average Auckland power bill has climbed significantly. Additionally, with major banks like ANZ and ASB now offering 1% (or interest-free) “Green Home Loans,” the ROI for solar in 2026 has shifted. This article has been updated to reflect these new costs and the latest smart-battery technology available at AVID Solar.
If you’re considering installing a solar panel system on your home, you may also be wondering what size battery you need to go along with it. The size of the battery you need for your home solar system will depend on several factors, including your energy needs, the size of your solar panel system, and how much energy you want to store for later use.
Here are some use case examples to help you determine what size battery you may need:
- Small Solar Panel System: If you have a small solar panel system and your energy usage is relatively low, you may only need a small battery to store excess energy. A 5kWh battery may be sufficient in this case.
- Medium Solar Panel System: If you have a medium-sized solar panel system and your energy usage is moderate, you may need a larger battery to store excess energy. A 10kWh battery may be sufficient in this case.
- Large Solar Panel System: If you have a large solar panel system and your energy usage is high, you will likely need a larger battery to store excess energy. A 20kWh battery or larger may be necessary in this case.
It’s important to note that the size of the battery you need will also depend on how much energy you want to store for later use. If you live in an area where there are frequent power outages or you want to be completely off the grid, you may need a larger battery to ensure you have enough stored energy to power your home during an outage.
