A recent electricity bill, the property address, information about any existing solar, and a simple explanation of your goals are enough to start. More detailed information can be added later if the project needs it.
What matters most
You can begin with a recent electricity bill, the property address, details of any existing solar and a clear description of what you want help with. More detailed information can be added if the assessment shows it is needed.
- A recent electricity bill is enough to begin the first review.
- Existing solar details help explain what is already at the property.
- Your goals and likely future changes guide the next questions.
Common questions
Do I need to know the right system size first?
No. The first review starts with your electricity use, property and goals. System size comes later in the assessment.
What if I only have a recent electricity bill?
That is enough to begin. If more detail is needed, Mark can explain exactly what information to provide next.
1. A recent electricity bill
The bill can show how much electricity you use, the tariff, supply charges, solar exports and other charges that may matter. For a business, it may also show demand information.
2. The property address
The address helps assess the location, likely solar resource, property type and roof or site constraints. A postcode can also be useful early in the discussion.
3. What you want to achieve
Different customers have different reasons for looking at energy. You may want lower bills, better use of existing solar, battery storage, EV charging, backup power or a clearer understanding of whether an investment makes sense.
4. Existing solar details
If you already have solar, useful information includes the approximate system size, age, inverter brand and model, and any monitoring information you have. A clear photo of the inverter label can often help.
5. Your usage pattern
You do not need perfect data to start. Even knowing whether most electricity is used during the day, in the evening or overnight can help guide the next questions.
6. Future changes
Tell me about anything likely to change energy use, such as an EV, new machinery, electric hot water, air conditioning, business growth or replacing gas appliances.
For commercial projects
Interval or smart-meter data can be very useful because it shows when the business uses electricity throughout the day. Operating hours, days of operation and major equipment can also help explain the load profile.
You do not need everything on day one
If all you have is a recent bill and a clear idea of what you want help with, that is enough to begin. The purpose of the first assessment is partly to identify what information is still missing.
What I do not expect you to know
- The exact solar size you need
- The exact battery capacity you need
- Which inverter or panel brand should be used
- Whether a battery is definitely worthwhile
- Technical network or export requirements
Those are part of the assessment and proposal process. The customer should not need to choose the equipment before the energy problem has been understood.
