Why Add Battery Storage to Your Solar System?

A standard solar panel system generates power during the day, but without a battery, any energy your home doesn’t use immediately gets exported to the grid for minimal feed-in credits. That means you’re still buying expensive grid electricity every evening and overnight, even though your panels generated more than enough energy during the day.

A solar battery changes that equation completely. It stores your surplus daytime solar energy and releases it when you need it, in the evening, overnight, and during peak tariff periods. The result is dramatically higher self-consumption, lower grid dependence, and for many Central Coast households, electricity bills approaching zero.

Whether you’re installing a new solar and battery package or retrofitting a battery to your existing solar system, Central Coast Energy will design the right solution for your home and energy goals.

  • Use solar energy 24/7
  • Blackout protection available
  • NSW battery rebate eligible
  • Slash grid dependence by 80–90%
  • Retrofit to any existing system
  • 10-year workmanship warranty

Frequently Asked Questions

Solar Battery Storage FAQs

Common questions Central Coast homeowners ask about solar battery systems.

Solar battery prices in NSW typically range from $8,000–$16,000 installed, depending on the brand, capacity and whether it’s a new install or retrofit. A Tesla Powerwall (13.5kWh) sits at the higher end, while a Sungrow SBR (9.6kWh) offers a more affordable entry point. NSW battery rebates through the PDRS can reduce your upfront cost further.

For most Central Coast households with solar, a battery is increasingly worth it — especially with rising electricity prices and declining feed-in tariffs. A battery typically boosts your self-consumption from 30–40% to 80–90%, meaning you buy far less from the grid. With NSW battery rebates and flexible finance, the financial case continues to improve year on year.

Yes — we retrofit batteries to any existing solar system on the Central Coast, even if it wasn’t installed by us. Depending on your current inverter, we may install an AC-coupled battery (like the Tesla Powerwall) which works alongside any inverter, or recommend a hybrid inverter upgrade for the best long-term performance. We’ll assess your setup during the free consultation and recommend the best approach.

The right battery size depends on your evening and overnight energy consumption. A typical Central Coast household uses 8–15kWh between sunset and sunrise. A 10kWh battery covers most of that for a standard home, while a 13.5kWh battery (like the Tesla Powerwall) provides more headroom for larger households. We analyse your usage data to recommend the ideal size.

It depends on the battery model and how it’s configured. Tesla Powerwall, Enphase IQ Battery and Alpha ESS SMILE all offer blackout protection — meaning they can power essential circuits (lights, fridge, internet) during a grid outage. Sungrow batteries can also provide backup with the right hybrid inverter. We’ll discuss your blackout protection needs during the consultation.

Yes. The NSW Government’s Peak Demand Reduction Scheme (PDRS) provides financial incentives for eligible battery installations, reducing your upfront cost. The rebate amount varies based on battery size and your electricity distributor. We handle all the paperwork and ensure your system meets the eligibility requirements.

How It Works

How Solar Battery Storage Works

Understanding the daily cycle of a home battery system helps you see why it’s such a powerful addition to your solar panels.

01

Morning & Daytime

Your solar panels generate electricity. Your home uses what it needs first — powering lights, appliances, air conditioning and hot water.

02

Surplus Stored

Any excess solar energy that your home doesn’t use is stored in your battery instead of being exported to the grid for minimal credits.

03

Evening & Night

When the sun goes down, your battery kicks in — powering your home with stored solar energy instead of expensive grid electricity.

04

Grid Backup

If your battery runs low, your home seamlessly draws from the grid as normal. Some batteries also provide blackout protection for essential circuits.
