Find The Right System For Your Business

Solar systems should be sized to meet your needs. This has nothing to do with just the available roof or ground space at your site, but has everything to do with your energy consumption.

Researching solar systems may return different results depending on the analysis provided by other solar businesses. This can cause confusion as to what the right system should be.

However, if you follow the steps below you will arrive at the right system that matches the needs of your business.

The right system needs to match the load profile of your business. Our team models 12 months of energy data to understand a business' load profile.

The right system should not export excessive amounts of power. It is important to note how much exported power is generated by the system because this will not yield a financial benefit. 

Coloured Fractal_2

The right solar system needs to be electrically and structurally engineered for your site. Getting the right certifications for your area is critical for a compliant install.

The right system doesn't impact your cashflow and improves your bottom line. It doesn't require you step away from your core business to manage and provides your business with long term energy price certainty. 

System Sizes and Types

Small to Medium Businesses

Solar systems from 30kW - 75kW are suitable for retail stores, offices and small clubs. These fall under the STC scheme and benefit from an upfront rebate. These systems generally have a payback of 2-4 Years.

A 50kW system should generate ~70,000kWh per annum with an estimated saving of $11,200.

Large Businesses

100kW solar systems should generate ~140,000kWh per annum and save a business $22,400 off their energy bills.

Businesses that require 100kW are typically; manufacturing goods, producing food and beverages, small clubs and pubs. This is the largest system size that falls under the STC renewable credit and CDC exemption.

Commercial & Industrial

For solar systems above 100kW things can get interesting. If your building has multiple meters then there is an opportunity to divide the system into smaller systems e.g. 3 x 100kW systems and claim STCs for each.

In most cases you will know if you have multiple meters because you will receive multiple energy bills - if you're still not sure then feel free to talk to our team.

Large Industrial

500kW - 1MW solar systems are suitable for large manufacturing sites, cold storage facilities with multiple chillers, distribution warehouses and large clubs.

This range of system size is generating 350-700MWh in electricity and energy savings in the vicinity of $120,000. 250kW-500kW solar systems are often installed on a business' roof, however small ground mounted systems are common in this tier also.

Large Scale Systems

1MW+ solar systems are typically adopted by large commercial and industrial businesses. Solar systems at this scale are still installed on a business roof, however roof availability is a key factor.

These systems are often installed on agribusiness, manufacturing, water and waste treatment sites.

Solar Finance

Finance Options

You have three major finance options when investing in solar energy: CapEx, Power Purchase Agreement (PPA), and Lease.

Capital Expenditure can deliver the fastest return on investment and allow you to take ownership of all assets. This option is suitable for businesses with access to low-cost capital.

Learn About Solar Finance

Power Purchase Agreement (PPA)

A Power Purchase Agreement (PPA) is a contract to purchase solar energy at a fixed rate, which is becoming an increasingly popular procurement method for several reasons. Not only do PPAs require no capital outlay, but they also remove the risks associated with owning and maintaining the solar system yourself.

Solar Lease

A Solar Lease option removes the upfront capital requirement of a solar system and spreads the cost over 7-10 years. This option can deliver a cash flow positive outcome from day one.

No Upfront Costs

At Smart Commercial Solar, we work with several preferred funding partners that can structure finance options with no upfront cost, to deliver immediate savings to your business.
