Solar System Upgrades & Panel Replacements in Melbourne

Your solar system has worked hard for years, but age catches up. Panels lose efficiency, inverters wear out, and your energy needs probably look nothing like they did when the system was installed.

Whether you want to expand capacity, replace underperforming panels, or get your roof ready for battery storage, Enelex handles solar system upgrades and panel replacements across Greater Melbourne.

We are a Registered Electrical Contractor (REC) based in Macleod, with 10+ years of experience on residential and commercial jobs across Brunswick, Bundoora, Eltham, Northcote, and beyond.

Is Your Solar System Underperforming? Here is What That Means

Solar panels degrade at roughly 0.5 to 0.8% per year. That’s the reason why your 10-year-old 5kW system may be delivering the output of only a 3.5 to 4kW system. Add an ageing inverter and outdated technology, and you could be losing hundreds of dollars a year in solar generation you are simply not seeing.

The most common signs you need a solar upgrade or replacement

●  Increased quarterly electricity bills despite having solar
●  Reduced or inconsistent output shown by your monitoring app
●  An 8+ year old inverter, throwing fault codes
●  Pre-2015-installed panels, reflecting lower efficiency
●  High-load appliances like EV charger, ducted AC, or pool pump added
●  Non-compatibility of the current system with the addition
●  An official notice about your feed-in tariff expiring

A solar system upgrade means swapping out ageing panels, inverters, or batteries for more efficient ones, so you get more output and lower bills. As a licensed Melbourne electrician, Enelex assesses your system and recommends the most cost-effective path forward. No hidden costs.

What Our Solar Upgrade Services Include

Enelex covers every stage - from system audit to final commissioning.

Solar System
Health Assessment

We run a full diagnostic of your panels, inverter, wiring, and mounting before recommending anything. You get a clear written report - no upselling, no guesswork.

Solar Panel Upgrade or
Partial Replacement

Not every panel needs a replacement. If a string is underperforming due to shading, damage, or degradation, we do a targeted replacement, keeping what still works and keeping your costs down. We work with Jinko Solar, REC Group, Canadian Solar, Trina Solar, and SunPower (Maxeon).

Full Solar
System Replacement

When a modern high-efficiency system delivers a better return, Enelex manages the full replacement, including panel removal and disposal, new installation with updated racking, inverter replacement or hybrid inverter upgrade, grid re-approval, and commissioning.

Solar System
Capacity Expansion

Need more output from your existing solar? We add panels, upgrade to a larger inverter, or move to a hybrid inverter ready for battery storage. Common scenarios: 3kW → 6.6kW expansion, single-phase to three-phase (commercial), or standard to hybrid inverter.

Battery-Ready
Upgrade Preparation

Planning to add a battery later? We select battery-compatible inverters and install the right wiring infrastructure upfront - so you're not paying for a second installation down the track.

Upgrade or full replacement - not sure what you need?

Solar System Upgrade Costs in Melbourne

Costs depend on system size, panel brand, inverter type, and roof complexity. Here is a general guide for 2025 to 2026.

Upgrade Type Typical Cost
Partial panel replacement (2 to 4 panels) $600 to $1,500
Inverter replacement only $1,000 to $2,500
System capacity upgrade (panels + inverter) $2,000 to $5,000
Full system replacement (6.6kW) $4,500 to $8,000
Battery-ready hybrid inverter upgrade $2,000 to $3,500

Small-scale Technology Certificates (STCs) may apply to new panels under the federal government's solar rebate scheme, which can reduce your out-of-pocket cost. We will advise on applicable rebates as part of your quote.

Frequently Asked Questions

If your system is producing significantly less than it used to, your inverter is faulting regularly, or your bills have gone up despite having solar, an upgrade assessment is a smart first step. Enelex does a full diagnostic inspection and provides a written report so you can make an informed call, whether that is a repair or a full upgrade. We will not recommend more than your system actually needs.
Yes. In many cases, a partial upgrade makes more financial sense. If your panels are still performing but your inverter is ageing, we replace the inverter only. If a handful of panels are underperforming due to damage or shading, we swap those out. We assess the whole system and recommend the most efficient path, not the most expensive one.
It depends on the upgrade type and your current retailer agreement. In Victoria, adding panels or replacing your inverter can affect your feed-in tariff rate under certain contracts. Enelex reviews your tariff arrangement as part of the assessment and advises you on any implications before we touch anything. No surprises on your next bill.
Yes. Replacement or additional panels may qualify for Small-scale Technology Certificates (STCs) under the federal Small-scale Renewable Energy Scheme, which effectively reduces the cost of your upgrade. The rebate amount depends on the number of panels, your location, and the year of installation. We calculate your STC entitlement and include it in your quote.
Most residential upgrades, including partial panel replacements or inverter swaps, take 3 to 6 hours on-site. A full system replacement is typically a full day. Complex commercial upgrades or three-phase changes may need two days. We confirm the timeframe during your quote and keep you updated throughout.
We remove and dispose of them responsibly. In Victoria, panel disposal is increasingly important because panels contain glass, aluminium, and silicon. We follow current best-practice disposal protocols and direct panels to recycling facilities where available. All removal is handled as part of your upgrade.
Absolutely. This is one of the most common upgrades we do in Melbourne right now. The main step is replacing your existing string inverter with a hybrid inverter, which manages both solar generation and battery charging. Enelex completes the upgrade and makes sure your switchboard, wiring, and metering are all ready for a future battery, saving you cost and rework later. See our Battery Storage Systems page for more details.
