Can I add a solar battery to my existing solar panel system?

Introduction

Solar batteries have been around for years, but they were previously only cost-effective for a small number of solar systems, mostly off-grid systems. However, recent advances in battery technology and reductions in battery prices have made solar storage batteries a viable option for many grid-tied solar systems as well.

When you installed your solar system a few years ago, batteries may not have been a cost-effective option. However, as battery technology improves and prices decline, you may want to consider adding energy storage to save even more on your energy bills.

Yes, you can add batteries to an existing solar panel system. There are different ways to do this, but before we discuss your options, let's briefly explain how batteries work.

Technician Installing A Solar Battery To An Existing Solar System

How Solar Battery Works?

When your solar panels generate electricity, it is converted to direct current (DC) electricity. The inverter then converts the DC electricity to alternating current (AC) electricity, which can be used to power your home or office. But what happens if your solar panels generate more electricity than you need?

This is where you can install a battery to store excess electricity generated by your solar panels. If you use more electricity than your solar panels produce, you can draw energy from the battery instead of relying on the grid.

Battery Installation Options for Solar Systems

Most grid-tied solar systems can be retrofitted with batteries, but the difficulty varies depending on a number of factors. Here are a few ways to add a battery to your solar system.

Solar System with Energy Storage

Plan for Future Battery Installation: Choose a battery-ready or hybrid inverter when installing solar panels to prepare for future battery installation. This saves money upfront and allows for flexibility in battery installation timing.
Easy Battery Integration: Adding a battery to a battery-ready system is the cheapest and simplest option, requiring less labor and materials compared to other methods.

DC Coupled System

Replace Existing Inverter: In a DC coupled system, your current inverter is replaced with a hybrid inverter capable of connecting to both solar panels and batteries.
Efficient Energy Conversion: The hybrid inverter converts DC electricity from solar panels to AC electricity for home use, minimising energy losses with a single conversion.
Suitable for Aging Systems: DC coupling is ideal for older solar systems with string inverters nearing the end of their lifespan, offering an efficient upgrade path to battery integration.

AC Coupled System

Utilise Existing Inverter: AC coupled systems use your existing inverter to convert DC electricity from solar panels to AC electricity, which is then sent to a storage inverter to charge the battery.
Ease of Installation: AC coupled systems are easier to install, more versatile, and generally less expensive than DC coupled systems.
Versatility: AC coupled systems can be used with a wider range of inverters and offer flexibility in system design.
Slightly Lower Efficiency: While AC coupled systems are efficient, they involve additional conversions between DC and AC electricity, resulting in slightly lower efficiency compared to DC coupled systems.
