Welcome to GridFree Solar — your trusted partner for solar installation, battery storage and rebate-claims in Melbourne.
Our Story
Founded with a mission to make sustainable, affordable energy accessible, GridFree Solar combines expert technical know-how with genuine customer service. We realised that while many homes in Victoria install rooftop solar panels, most of the solar energy they generate is exported to the grid or lost. By adding a battery storage system, you keep that energy for yourself — using it at night, on overcast days or during peak pricing periods. That means far lower power bills, and more control. We also navigate the complex world of rebates and government incentives for you.
Our Vision

With a larger battery, you don’t have to charge or drain it fully each day. Keeping the battery between 40% and 60% charge helps it last much longer — up to four times longer than normal.
With a typical electricity price difference of $0.40/kWh, and 20kWh daily usage, customers save around $8 per day — most recover their investment in under 2 years.
At GridFree Solar, we bring together innovation, efficiency, and sustainability — empowering Melbourne homes to take full control of their energy future. From top-tier solar panels to intelligent hybrid systems, every solution is designed for maximum savings and performance.
Safest, most thermally stable battery chemistries with lower fire risk and better heat tolerance than alternatives.
Our models are engineered for 8,000+ cycles and 15+ year design life, making them cost-effective over time.
Batteries can be stacked and expanded easily as your energy needs grow, from small residential setups to larger commercial systems. Scalability means you don’t have to overspend upfront.
Compatible with many hybrid inverters and controllers commonly used in Australian solar systems, supporting retrofit or new installations without proprietary inverter lock-in.
High depth of discharge (DoD) and efficient charge/discharge performance mean more of your generated solar energy is stored and used rather than wasted.
Integrated BMS safeguards against over-charge/discharge, over-current, and temperature extremes, protecting battery health and extending service life.

Panels convert daylight to DC power, which an inverter turns into usable AC electricity; surplus can charge a battery or export to the grid. Output drops on cloudy days (design around annual averages, not one sunny day), and panels don’t generate at all after dark — you draw from a battery if you have one, otherwise the grid.
Panels typically carry long performance warranties, but compare three separate things: the product warranty, the performance warranty, and the installer’s workmanship warranty.
Base sizing on annual consumption, daytime load, roof space, tariff, and future plans (EV, heat pump, battery) rather than a generic number. 6.6 kW suits some homes, but electrified or high-demand households often need more.
Usable roof area, panel wattage and layout determine capacity. North-facing roofs often maximize annual output; east/west can spread generation across the day. South-facing isn’t automatically ruled out — model it. Shading from trees, chimneys or vents should be assessed, not assumed.
Approval requirements vary by council, network and property type — your provider should confirm these. Rentals can proceed with owner consent; strata/apartment installs usually need Owners Corporation approval and a clear allocation plan; new builds may face different rebate eligibility, so confirm before signing.
Future expansion depends on inverter limits, export limits and roof layout — check compatibility upfront. Solar may improve buyer appeal, but treat bill savings, not resale value, as the core business case.
Most inverters include a monitoring app; ask whether it tracks whole-home consumption, not just generation. Panels usually just need occasional rinsing from rain, with cleaning only if soiling or performance issues justify it.
A standard grid-connected system shuts off in an outage for safety — backup requires compatible battery/inverter equipment and a designed backup circuit. Solar can offset an air conditioner, EV charging (ideally with smart charging), or a pool pump when run during sunny hours.
Self-consumption is solar power used at home rather than exported; the feed-in tariff is what retailers pay for exports. Since import prices are usually much higher than feed-in rates, using solar directly is generally worth more than exporting it.
Savings depend on generation, daytime usage, tariff, exports, weather and future prices — always use a conservative written estimate. A proper estimate needs 12+ months of bills, tariff details, interval data if available, and expected future loads.
Payback period is net upfront cost divided by estimated annual savings — a screening tool, not a full financial analysis. Quotes vary because installers assume different tariffs, export rates, degradation and consumption profiles; compare assumptions line by line.
eigh total finance cost against conservative savings estimates — a low monthly repayment doesn’t prove good value. Compare quotes on system size, brand/model, inclusions/exclusions, warranties and install scope, not price alone.
No — a low feed-in tariff just makes self-consumption more valuable (load shifting, batteries, efficient appliances help). Eliminating your bill entirely isn’t reliable, since fixed charges, night use and seasonal variation can persist.
Output declines gradually over a panel’s life — use manufacturer warranty terms rather than assuming zero degradation. Post-install costs can include switchboard work, meter changes, repairs, monitoring fees or battery replacement.
Distributors may cap how much you can export, affecting inverter and battery settings (this cap can also be “dynamic,” varying with network conditions). Your retailer’s import/export rates and time-of-use structure can materially change outcomes — model any tariff switch using real usage data.
Get assumptions in writing, test high/medium/low scenarios using your own bills, and separate incentives from ongoing savings. Savings are never guaranteed — weather, usage and tariffs all vary, and warranties don’t equal savings guarantees.
The best size fits your load, roof and network constraints — not simply the largest option. An EV or heat pump can boost ROI if scheduled to run during solar hours, increasing self-consumption.
Look at manufacturer track record, warranties, local support and site suitability for both panels and inverters. Premium components are worth it only when justified by site needs, warranty terms or service — not marketing alone.
A standard inverter converts DC to AC; a hybrid inverter is designed to also work with a compatible battery. Microinverters sit at each panel (useful for complex/shaded roofs); optimisers manage panel-level performance in certain layouts — compare cost and serviceability for each.
Neither is universally superior — choose a proven, compatible, well-supported system. You should receive written warranties covering panels (product and performance), inverter, battery, and workmanship, with clear claims contacts for each.
Clarify the retailer’s after-sales process, manufacturer contacts and installer responsibilities before buying. A proper site visit is strongly preferable for complex homes or battery installs; remote designs should still verify photos and switchboard details.
Older or full switchboards may need upgrading for safety or compliance before connecting solar/battery equipment. A smart meter may also be required for exports, tariff changes, or battery optimisation — check your retailer/distributor’s process.
Competent installers use proper mounting/flashing and should offer roof warranty coverage for penetrations. Most solar-only jobs take a day; batteries, switchboard work or approvals can extend the timeline.
Expect a quote, contract, system design, datasheets, warranties, certificates, commissioning records and monitoring access. Commissioning is the final testing/configuration process confirming safe, correctly configured operation.
Verify licences/accreditation, insurance, reviews and complaint handling. Treat any sales channel the same way — get a written quote, check credentials, confirm cooling-off rights, and avoid pressure to sign on the spot.
Manufacturer warranties can survive, but workmanship support becomes harder — this is why retailer stability and documentation matter. All work must meet applicable Australian standards, network rules and electrical regulations.
A battery stores surplus solar for evening use, cuts grid imports, and can provide backup if designed for it — but compatibility depends on your existing inverter, battery type and switchboard, so not every battery will work with your setup.
AC-coupled batteries often suit retrofits; DC-coupled can be more efficient with a compatible hybrid inverter — site-specific design decides. Size using interval consumption data, evening demand, tariff and outage priorities, not just to chase a rebate; compare usable capacity, not nominal capacity.
Only if specifically designed for whole-home backup with adequate inverter power — many systems back up selected essential circuits (lighting, fridge, internet) instead. Some compatible systems can even recharge from solar while islanded during daylight.
Some batteries can charge from the grid depending on settings, tariffs and program rules. Yes — bill savings from storing and timing solar use are separate from any backup function.
Compare warranty years, throughput and retained capacity, not cycle count alone. Usable capacity does decline over time — check what retention the warranty promises.
Location is constrained by manufacturer instructions, fire safety and standards (garages are often possible with the right clearances). Properly selected, installed and maintained batteries are designed to be safe — don’t compromise on installer quality or placement.
Sometimes — check model compatibility, expansion limits and whether matching modules stay available. Replacing an old inverter can make sense if it’s near end-of-warranty, undersized, or incompatible with the battery.
Usually yes, since surplus is stored before being exported. Batteries can make financial sense with high evening use and low feed-in rates — run a conservative case and value backup separately from bill savings.
A Virtual Power Plant coordinates participating batteries, potentially offering payments or credits in exchange for dispatch rights. Before joining, read the contract carefully for payment terms, exit fees, control rights, reserve levels and warranty impact.
Yes, if sized and configured to discharge during high-price periods. Power rating (kW) determines what loads it can actually run — a big kWh capacity with low kW output may not cover everything — and your interval data is essential for correctly sizing and valuing the system.
Solar Homes offers a PV rebate up to $1,400 (50% of eligible cost after STCs) plus an optional interest-free loan up to $1,400, repaid over four years, generally requiring installation within 120 days of approval. Eligibility broadly requires combined taxable household income under $150,000, property value under $3 million, owner-occupier status, and no solar at the property in the prior 10 years (separate landlord pathways exist). There is currently no standalone Victorian state battery rebate.
It’s an STC-based upfront discount for eligible battery installs, typically applied through the installer’s quote and generally not income-tested. From 1 May 2026, the STC factor is 100% for the first 14 kWh, 60% for capacity from 14–28 kWh, and 15% for capacity from 28–50 kWh — with eligibility based on installation date, not contract signing date.
It offers zero-interest loans up to $15,000 (repayable over up to 10 years) for eligible households with combined taxable income up to $210,000, covering rooftop solar and household batteries among other upgrades. It’s still a loan requiring repayment — not free money — and targeted discounts up to $4,000 have also been flagged for lower-income/concession households and renters (with landlord permission), subject to current program rules.
Some incentives may stack, but never promise this without checking the specific customer, address, equipment and application pathway. Before signing, confirm: exact system design, quote validity, incentive assumptions, eligibility, installation timing, finance terms, warranties, exclusions, and backup/grid design — and keep documentation (bills, interval data, ID, ownership/consent) ready.
