Small Business Solar That Matches Your Operating Hours
Unlike residential solar, small business systems are designed around your operating schedule. A retail shop, warehouse, or office that operates Monday to Friday during daylight hours can offset the majority of its energy draw with a correctly sized solar system. MainSwitch Energy analyses your actual energy data before sizing your system.
We handle the full process end-to-end: CEC-compliant system design, DNSP grid connection approval, AS/NZS 3000 compliant installation by our own licensed team, and 24/7 after-install support. Installations are scheduled around your business hours – most small business systems are commissioned over a single day or weekend.
Why Melbourne Small Businesses Are Switching to Solar
Energy costs represent a significant and growing portion of small business operating expenses in Melbourne. Unlike residential users, small businesses typically consume most of their power during daylight hours – exactly when solar panels generate at maximum output. The alignment between solar generation and business consumption makes small business solar one of the highest-returning energy investments available.
Small businesses may also be eligible for the federal STC rebate, which reduces upfront installation costs. MainSwitch Energy applies all available incentives to your quote and advises on current Victorian and federal programs that apply to your business type and system size.

What Size Solar System Does a Melbourne Small Business Need?
System size for a small business depends on your monthly energy spend, daily consumption profile, roof space, and whether you want battery storage for after-hours use. A small office or retail shop typically starts at 10 kW. A warehouse or light manufacturing facility may require 20 to 30 kW or more. MainSwitch Energy will assess your bills and site before recommending a system – not a generic size estimate.
All MainSwitch Energy small business installations include grid connection documentation, commissioning reports, and full warranty paperwork suitable for your business asset register or lease documentation.

Yes. Battery storage extends the value of your solar generation to after-hours periods – useful if your business has evening or overnight energy consumption, or if you want backup capability during grid outages. We assess your after-hours consumption and grid tariff structure to determine whether battery storage makes economic sense for your specific situation, and quote it as an option alongside the solar system.

A small business solar installation of 10 to 30 kW on a standard commercial roof typically takes two to three days – one day for roof work and one to two days for electrical installation, metering, and commissioning. Larger or more complex installations are scoped individually. We plan the installation schedule to minimise disruption to your trading operations.
We plan installations to minimise operational disruption. Roof-mounted panel installation typically does not require any power interruptions. The electrical connection work – inverter installation, switchboard connection, and metering – requires a brief planned outage, typically one to two hours. We schedule this during your lowest-activity period. We confirm the disruption plan with you before booking the installation.
We install commercial-grade panels and inverters from leading manufacturers with proven Australian performance records and responsive local warranty support. Specific product recommendations are made based on your system size, roof type, and budget. We do not specify products based on margin – we specify based on what performs reliably in Melbourne conditions and carries strong warranty backing.
In most cases, commercial solar installations on existing buildings are permitted development and do not require a planning permit in Victoria. Exceptions include heritage-listed buildings, buildings in certain overlay zones, and installations that alter the building facade in a visible way. We advise on planning requirements as part of the site assessment and manage any required approvals.
Commercial solar systems should be inspected at least annually, with performance data reviewed against expected output each quarter. Key maintenance items include panel cleaning, DC isolator and connection inspection, inverter performance verification, and mounting system integrity checks. Main Switch Electrical offers fixed-price annual and biannual maintenance programs for all commercial systems we install.
