Solar costs vary by system size, equipment, roof requirements and installation complexity. At Polygon Energy, we design systems around your energy usage rather than simply offering the cheapest package.
For many Australian homes, solar can reduce grid dependence and electricity costs. The value depends on your energy consumption, solar generation, electricity rates and system design.
Battery costs depend on capacity, technology, installation and applicable incentives.
A battery can help store excess solar and use it when household demand is higher, particularly in the evening.
The right size depends on your electricity consumption, solar generation, evening usage, backup requirements and future energy needs. Polygon Energy designs systems using actual consumption data rather than assumptions.
The program provides financial support for eligible battery installations through the Small-scale Renewable Energy Scheme. Polygon Energy helps customers understand the applicable incentive and design a battery solution around their requirements.
The incentive varies according to eligible battery capacity and the current program rules. From May 2026, the incentive structure became tiered, making appropriate battery sizing increasingly important.
There is no single best system for every home. Polygon Energy considers your consumption, property, budget, backup requirements and future electrification plans to design the right combination of solar, battery and energy management.
Don’t compare quotes on price alone. Look at system design, equipment, expected generation, warranties, installation quality, monitoring and after-sales support.
Look for relevant accreditation, qualified installers, quality equipment, transparent warranties and proven installation experience. Polygon Energy is a NETCC Approved Seller and takes an engineering-led approach to solar and battery design.
Solar generation depends on system size, location, roof orientation, shading, weather and equipment. Polygon Energy assesses these factors when estimating expected system performance.
Payback depends on system cost, electricity consumption, solar generation, electricity prices, feed-in tariffs and available incentives. Polygon Energy assesses these variables when evaluating system economics.
Quality solar panels are designed for long-term operation and typically come with product and performance warranties. Polygon Energy considers both equipment quality and long-term reliability when selecting products.
Battery lifespan depends on technology, usage, operating conditions and warranty specifications. Polygon Energy considers battery performance, usable capacity and warranty coverage when recommending storage.
Yes, if the system is specifically designed for backup power. Polygon Energy can configure battery systems with backup circuits to keep selected critical loads operating during an outage.
Battery size should reflect your daily energy consumption, solar generation, evening demand and backup requirements.
The best equipment depends on the application. Polygon Energy considers efficiency, reliability, warranties, compatibility, monitoring and long-term performance when selecting solar panels and inverters.
Consider product, performance and installation warranties separately. It’s also important to understand what is covered, for how long and who is responsible for support.
The system is commissioned and connected according to the applicable requirements. Polygon Energy also provides ongoing monitoring and maintenance options to help customers track system performance and identify issues.
