Commercial Solar Melbourne
Commercial solar returns around three times the value of residential solar. Your business consumes power at the moment it is generated, offsetting the full commercial tariff of 25 to 30 cents per kWh.
Helcro Solar has provided solar panel installation in Melbourne for over 18 years. We carry the CEC Approved Solar Retailer accreditation and install solar PV, solar plus battery, and battery-only systems from 30kW to 250kW.

Why Commercial Solar Now
Your single highest peak draw, even once or twice a year, sets your demand tariff for the whole period. Shaving that peak with solar and battery storage can save tens of thousands of dollars annually.
For owners, a solar system lifts building valuation. At a 6% yield, one producing $200,000 per year in value adds roughly $3.5 million to the property, refinanceable against the asset.

Owners and Leaseholders
Commercial solar works for leaseholders too. A 5+5+5 or 10-year lease easily captures a 3 to 4 year payback, leaving years of savings ahead, while the landlord benefits from a higher building valuation.

Commercial Solar by Industry
Helcro Solar designs commercial solar systems for Melbourne properties across eight sectors. Every system is built around the specific energy profile of that property type, not a catalogue size.
3 PHASE SOLAR SYSTEMS
Almost all Victorian commercial premises operate on three-phase power. Every Helcro Solar commercial design is configured specifically for a 3 phase connection, balancing generation evenly and avoiding grid export penalties.
Our Process
Every engagement starts with a free remote savings assessment. The financial analysis comes first. Only when the numbers make sense do we progress to site visits and proposals.
Commercial Solar Incentives
Victorian commercial solar systems access two distinct federal incentive schemes depending on system size. Helcro Solar determines which applies and manages the full application process.

Frequently Asked Questions
For most Melbourne commercial properties, a payback period of 3 to 4 years is realistic. Commercial returns are significantly stronger than residential for a fundamental reason: the business consumes the power at the moment it is generated, at the full commercial tariff rate of 25 to 30 cents per kWh, rather than exporting it to the grid for a fraction of that. Facilities with the strongest daytime energy loads, including fabricators, manufacturers, cold storage operators, and logistics facilities, tend to achieve paybacks toward the lower end of that range. Helcro Solar calculates the exact payback and return on equity for your site using real interval meter data and models multiple scenarios so you can choose the outcome that best matches your financial objectives.
Yes, and the economics can be compelling even on leases that are partway through their term. A commercial leaseholder on a 5+5+5 structure has 15 years of occupancy available, easily capturing a 3 to 4 year payback with over a decade of full savings still ahead. Commercial leaseholders hold the electricity bill for the life of their tenancy and therefore capture the full benefit of any reduction in usage costs and demand charges. Landlords are also frequently willing to co-invest because it lifts the building's bankable valuation. Helcro Solar models the financial case against your specific lease structure and remaining term.
The best commercial solar system depends on your energy consumption profile, roof space, and whether your business operates primarily during the day. For most Melbourne commercial properties, a grid-connected system between 30kW and 100kW is the most cost-effective starting point, with 100kW being the most common size. Businesses with significant demand charges benefit from pairing solar with battery storage to shave peak draw and reprice their tariff. Helcro Solar designs every commercial system around actual energy data from your bills and usage profile, modelled through Orchestra to find the optimal configuration.
The 33% rule is a guideline in commercial solar design stating the combined DC capacity of solar panels should not exceed 133% of the inverter's rated AC output. For example, a 30kW inverter can support up to approximately 40kW of panels. This deliberate DC oversizing is standard practice because panels rarely operate at rated peak output simultaneously. The additional panel capacity compensates for reduced output during early morning, late afternoon, and cloudy periods, resulting in higher overall generation without requiring a larger inverter. Helcro Solar applies DC oversizing calculations to every commercial system design.
Yes. Three finance structures are commonly available. A Power Purchase Agreement (PPA) involves a third party owning the system and selling you the electricity it generates at a contracted rate below your current tariff, meaning zero upfront cost and savings from day one. A solar lease involves leasing the equipment over a fixed term with options to purchase. A chattel or asset mortgage involves borrowing to purchase the system outright. The underlying economics remain strongly positive: a well-designed system typically generates a return of around 20% per year on its installed cost, against a typical finance rate of around 7%.
Commercial solar systems are mounted using penetration-less rail and clamp systems wherever structurally possible, using S5-certified clamps that grip existing roof ribs or seams rather than drilling through the membrane. This protects roof integrity and preserves existing waterproofing warranties. Every commercial installation includes a structural engineering report confirming the roof can carry the panel and racking load.
Commercial solar systems are designed to Australian and international safety standards and include rapid shutdown capability, arc fault detection, earth leakage protection, and DC isolators at the inverter and array level as standard. Battery systems installed as part of a commercial solar project are rated to relevant fire and safety standards. Helcro Solar assesses site-specific requirements for high-compliance environments including food production, aged care, and logistics facilities where safety certification is a procurement requirement.
