Best Solar Plans NSW: 2025 Guide

Why Compare Solar Plans in NSW?

With over a million rooftop solar installations and more than 32% of NSW homes now powered by solar, finding the best solar plan is crucial for maximising your energy savings. Whether you’re a homeowner or a business, the right solar plan can help you reduce your bills, earn credits for excess energy, and support your sustainability goals.

How Solar Feed-In Tariffs Work

A solar feed-in tariff (FiT) is a credit you receive for every kilowatt hour (kWh) of excess solar energy your system exports to the grid. In NSW, there’s no government-mandated minimum FiT, so rates are set by individual retailers and can vary widely. As of July 2025, the highest FiTs in NSW are up to 10c/kWh for the first 8–12kWh per day, with lower rates for additional exports.

Note: Maximum rates may only last for a set period (often 12 months). Always check the plan’s terms and conditions.

What to Consider When Choosing a Solar Plan

Feed-in Tariff Rate: Higher FiTs can boost your savings, but check if they’re capped or time-limited.
Usage and Supply Charges: Some plans with high FiTs may have higher daily or usage rates. Compare the total cost, not just the FiT.
Contract Terms: Look for contract length, exit fees, and whether FiT rates are fixed or variable.
Sun Tax: From July 2025, some NSW networks (e.g., Endeavour Energy, Ausgrid) may charge a small fee for exporting solar during peak periods. Batteries can help you avoid these charges by storing excess energy for later use.
Plan Suitability: The best plan depends on your solar system size, export patterns, and whether you’re a household or business.

Solar Rebates and Incentives in NSW

Federal STC Rebate: Reduces upfront cost of solar systems for eligible homes and businesses.
NSW Battery Rebate: Additional support for installing solar batteries (check eligibility).
Solar for Apartments: Up to 50% off shared solar systems for apartment buildings (via NSW Climate and Energy Action).

Maximising Your Solar Savings

Self-Consumption: Using your solar energy directly is more valuable than exporting it, as grid electricity rates are higher than FiTs.
Smart Monitoring: Use your provider’s app or a power usage monitor to track exports and optimise usage.
Regular Plan Reviews: Solar plan rates and FiTs change frequently. Review your plan annually to stay competitive.
