Free energy assessment

Your free energy assessment: a system designed on your own numbers.

We review your bill, your usage and your site, then give you a report with system size, equipment list and payback time.

Start an assessment

Is your system sized on a guess?

Does this sound familiar?

  • Your quote was a generic template, not based on your own bill.
  • If you run a business, you do not know what demand charges are doing to your bill.
  • Nobody has looked at your roof, your DB board or how the building really uses power.
  • You are not sure what size of system you actually need.

We believe a solar system should be designed on your own numbers, not a template.

Design around evidence, not assumptions.

Our energy audit and design is the free energy assessment. It is the same thing, and it costs you nothing. We review your bill and your usage, including demand charges. For big sites, we can log your usage on site for 1 to 2 weeks before we size anything.

Your system is designed in house, with FoxESS and Sigenergy inverters and batteries. EFJS Printing paid back its investment in 2.5 years.

And we can do the same for you.

What you get from your free energy assessment

Know your numbers first

We review your bill, usage and demand charges, which means the design is sized to what you really use.

See before you commit

You get a PDF report and a walk-through with your system size, equipment list and payback time, which means you decide with real numbers.

Fewer surprises on site

We look at your roof and electrical setup, which means the design fits your property.

Paperwork handled for you

CoC and SSEG application handled for you. SSEG fees and meter costs are included in our quotes, which means no surprise compliance bill later.

Backed by a 10-year swap-out warranty

Every system we fit carries a 10-year swap-out warranty on the inverter and battery, which means a faulty part gets swapped out, not left for you to chase.

Quick from first call to switch-on

First call to switch-on is about 1 to 3 weeks, depending on approvals, paperwork and the size of your system, which means you can plan your switch-on.

What we look at

Start with what
is already there.

We start with what is already there: your bill, your roof, your electrical setup and how your property uses power.

01

Electricity profile

Your bill and your past usage show what size of system you need.

02

Property layout

Your roof and the space you have shape the design.

03

DB-board context

Your electrical setup tells us how the system connects.

04

Equipment needs

How your building or home uses power decides what the system must carry.

05

What you want to achieve

Tell us what you want the system to do, and we design with that in mind.
