Got Questions?

Frequently Asked Questions

Here are the questions Melbourne homeowners and businesses ask us most.

  • What does a solar panel installation cost in Melbourne?

    The cost depends on your system size, roof type, and whether you're adding battery storage. Most residential systems in Melbourne range from $4,500 to $9,000 after government rebates are applied. MainSwitch Energy provides free, no-obligation fixed-cost quotes before any work begins - so the price we quote is the price you pay.

  • What areas of Melbourne do you service?

    MainSwitch Energy operates Melbourne-wide, with a focus on the North-East including Epping, South Morang, and Mernda. Whether you're in the inner suburbs or the outer metro fringe, call us on 1300 624 679 and we'll confirm coverage for your area.

Tesla Powerwall carries Tesla’s standard manufacturer warranty. Hive Solar Battery carries its own manufacturer warranty. MainSwitch Energy adds a lifetime workmanship warranty on top – covering any fault caused by how the battery was installed, for the life of the system.

The Victorian Government offers rebates to eligible households installing solar battery storage. Eligibility depends on household income, existing solar, property type, and battery system specifications. MainSwitch Energy assesses your eligibility as part of every quote and manages the application process – you do not handle the rebate paperwork.

We install Tesla Powerwall and Hive Solar Battery systems. Both carry strong manufacturer warranties and are proven in Australian conditions. MainSwitch Energy recommends the right product for your consumption profile and budget – we will tell you honestly if a particular battery is not the right fit for your situation.

Payback periods for battery storage in Melbourne typically range from 7 to 12 years depending on your feed-in tariff rate, time-of-use tariff structure, and daily consumption pattern. Available Victorian rebates can significantly shorten this. MainSwitch Energy can provide a projected payback estimate as part of your free storage assessment.

A full maintenance visit includes visual panel inspection, professional panel cleaning, inverter performance check and error log review, DC and AC connection integrity testing, monitoring system verification, and a written service report.

Call MainSwitch Energy on 1300 624 679. Our team will talk you through the fault code and attempt remote diagnosis. If an on-site visit is required, we will schedule it as soon as possible. For MainSwitch Energy installs, fault response may be covered under your lifetime workmanship warranty.
