Solar for Liverpool Businesses: What Data Do You Need for a Commercial Solar Assessment?

For a business in Liverpool NSW 2170, a useful commercial solar proposal should not begin with:

“How many panels can fit on the roof?”

It should begin with:

“How and when does this business use electricity?”

Commercial solar economics depend heavily on daytime consumption, electricity tariffs, operating hours, roof availability and network connection conditions.

Before a system can be sized properly, an installer should normally understand:

• At least 12 months of electricity bills

• Smart-meter or interval consumption data

• Business operating hours

• Roof or ground-space availability

• Property ownership or lease arrangements

• Existing switchboard and electrical supply

• Major electrical equipment

• Future electricity demand

• Network connection and export requirements

Kratos Energy's commercial solar solutions are built around energy audits, load profiles, tariffs and site-specific system design rather than standard residential-style packages. (Kratos Energy)

Commercial Solar Assessment: Quick Checklist

The more accurate the input data, the more useful the savings and payback model can be.

Why Commercial Solar Is Relevant in Liverpool

Liverpool is a major commercial and industrial centre in South-West Sydney.

Liverpool City Council reported in 2025 that the city had approximately 22,304 registered businesses supporting more than 114,000 local jobs, with transport, postal and warehousing its largest industry by economic value. (Liverpool City Council)

That business mix creates several property types that can potentially suit commercial solar:

• Warehouses

• Logistics facilities

• Retail premises

• Workshops

• Manufacturing sites

• Offices

• Medical facilities

• Service businesses

Many of these businesses operate heavily during daylight hours—the same period when rooftop solar is generating.

But two Liverpool businesses with the same roof size can require completely different solar systems if their electricity profiles differ.

1. Start With 12 Months of Electricity Bills

One electricity bill is rarely enough for commercial solar design.

A better starting point is 12 months of bills, because commercial consumption can change significantly across seasons.

The bills should help identify:

• Total annual kWh consumption

• Monthly or quarterly usage

• Electricity tariff

• Usage charges

• Demand charges, where applicable

• Network charges

• Controlled or separate loads

• Solar exports if a system already exists

Why 12 months?

Consider a business that uses:

40,000 kWh in summer

but only:

18,000 kWh in winter

Designing solar using only the summer bill could result in excessive generation for much of the year.

The objective is to understand the site's annual demand profile.

2. Interval Data Is More Important Than the Bill Total

For commercial solar, interval data is one of the most useful inputs.

A bill tells you:

how much electricity was used.

Interval data tells you:

when it was used.

Smart-meter data can show consumption across short time intervals throughout each day.

That helps identify:

• Morning demand

• Midday demand

• Afternoon demand

• Overnight baseload

• Weekend usage

• Seasonal patterns

• Maximum-demand periods

Example

Two businesses each use:

300 kWh/day

But:

Business A

Uses 250 kWh between 7 AM and 5 PM.

Business B

Uses only 100 kWh during the day and 200 kWh overnight.

Business A may have much greater potential to use solar directly.

Same daily consumption. Different commercial solar opportunity.

3. Operating Hours Help Determine Self-Consumption

Commercial solar is often particularly effective when the business operates while the sun is shining.

Examples include:

Warehouse

6 AM–6 PM

High daytime lighting, ventilation, office and machinery loads.

Retail store

9 AM–6 PM

Air conditioning, refrigeration, lighting and equipment align with solar production.

Workshop

7 AM–4 PM

Tools, compressors and machinery create daytime demand.

Restaurant

May have strong lunch and evening loads, requiring a different assessment.

This is why a commercial assessment should record:

• Opening time

• Closing time

• Days per week

• Weekend operation

• Seasonal shutdowns

• Public-holiday closures

The aim is to determine how much solar can be consumed directly by the business.

4. Identify Your Largest Electrical Loads

The installer should understand what is driving the electricity bill.

Typical commercial loads include:

• Air conditioning

• Refrigeration

• Cold rooms

• Pumps

• Compressors

• Manufacturing equipment

• Lighting

• Commercial kitchens

• Servers

• Machinery

• EV chargers

These loads can strongly influence solar sizing.

For example, a warehouse running large refrigeration equipment throughout the daytime may use solar very differently from a similarly sized warehouse used mainly for storage.

A good assessment should therefore connect:

electricity data → business equipment → operating schedule.

5. Future Electricity Demand Matters Too

Commercial solar should not be designed only around today's load.

Ask whether the business expects to add:

• Electric vehicles

• Fleet charging

• Additional refrigeration

• New machinery

• Expanded production

• Additional air conditioning

• Battery storage

• A second tenancy

• Longer operating hours

Suppose current daytime demand suggests a 50kW system.

If the business plans to install multiple EV chargers within two years, a larger system or battery-ready design may deserve consideration from the beginning.

Future expansion should be documented before final system sizing.

6. Roof Ownership Can Decide Whether the Project Moves Forward

Commercial properties are frequently leased.

That makes roof ownership and approval important.

Owner-occupied property

The business owner controls both the energy bill and building, usually simplifying the approval process.

Tenant-operated property

The tenant may pay the electricity bill while the landlord owns the roof.

In this situation, clarify:

• Who pays for the solar installation?

• Who owns the system?

• How long remains on the lease?

• Who receives the electricity savings?

• Who maintains the equipment?

• What happens when the lease ends?

• Who approves roof penetrations and access?

A solar project can have excellent technical economics but still be unsuitable if the lease arrangement does not support the investment period.

7. Assess the Roof Before Finalising System Size

Commercial buildings often have large roofs, but total roof area is not the same as usable solar area.

The assessment should consider:

• Roof dimensions

• Roof orientation

• Shade

• Roof material

• Structural condition

• Skylights

• HVAC equipment

• Ventilation

• Roof access

• Fire and maintenance access

• Existing services

For older commercial buildings, roof condition can be particularly important.

If major roof replacement is likely within the next few years, completing that work before solar may avoid the cost of removing and reinstalling the system later.

8. Check the Main Switchboard and Electrical Supply

A commercial solar system ultimately connects into the property's electrical infrastructure.

The assessment should record:

• Single-phase or three-phase supply

• Main switchboard condition

• Available switchboard capacity

• Existing protection equipment

• Supply capacity

• Metering configuration

• Existing generation equipment

Larger commercial systems may require more detailed engineering than a standard residential installation.

Kratos currently offers commercial systems from approximately 30kW through 100kW+, including customised designs. (Kratos Energy)

9. Network Connection Must Be Assessed Early

Liverpool postcode 2170 sits within the Endeavour Energy network area and is included in the first stage of the NSW CER Installer Portal rollout beginning 2 November 2026. Endeavour Energy says the new process will apply to new and upgraded consumer-energy-resource systems up to 200kW in applicable rollout areas. (Endeavour Energy)

For businesses, network assessment can affect:

• Inverter capacity

• Export limits

• Required technical studies

• Connection costs

• System design

• Installation timeline

Endeavour Energy specifically recommends that businesses assess their energy needs, roof space and future plans before selecting a solar or battery system. (Endeavour Energy)

For larger embedded-generation systems, a detailed network assessment may be required rather than the fast-track process used for smaller installations. (Endeavour Energy)

This is why commercial solar should not be designed solely around roof capacity.

How Export Limits Affect Commercial Solar

Imagine a Liverpool warehouse has enough roof space for 150kW of solar.

That does not automatically mean it should export 150kW.

The system could instead be designed so that much of the solar generation is consumed inside the facility.

For example:

Solar output: 120kW

Business demand at that moment: 100kW

Potential export: 20kW

High daytime self-consumption can make a large commercial system valuable even where export capacity is restricted.

The assessment therefore needs to model:

generation + onsite demand + permitted export

together.

What About Demand Charges?

Some commercial electricity tariffs include demand charges based partly on the site's highest demand during specified periods.

Solar may reduce demand charges in some circumstances, but it does not automatically eliminate them.

For example:

If a business's highest demand occurs at:

2 PM

solar may help reduce that peak.

If maximum demand consistently occurs at:

8 PM

rooftop solar alone may have little impact on that peak.

Interval data is therefore essential before including demand-charge savings in the business case.

Any financial proposal should explain separately:

• Energy-charge savings

• Export revenue

• Potential demand-charge impact

• Fixed charges that remain

Do You Need Battery Storage?

Not every Liverpool business needs a battery.

Battery storage deserves investigation when the site has:

• Significant solar exports

• High evening electricity use

• Demand-management opportunities

• Backup requirements

• EV charging

• Time-of-use pricing

For a warehouse that consumes most solar generation immediately during working hours, solar alone may already deliver strong utilisation.

A business closing at 5 PM but consuming heavily overnight may have a stronger case for storage.

Battery sizing should therefore follow the load analysis rather than being added automatically.

Example: Liverpool Warehouse Solar Assessment

Consider an illustrative Liverpool warehouse.

Annual consumption:

180,000 kWh

Operating hours:

7 AM–6 PM, Monday–Saturday

Major loads:

• Lighting

• Office air conditioning

• Forklift charging

• Ventilation

• Warehouse equipment

Interval data shows:

75% of electricity is consumed during daylight operating hours.

The roof can accommodate more than 100kW of panels.

What should happen next?

The assessment should compare multiple system sizes rather than immediately installing the maximum capacity.

For example:

50kW → higher self-consumption, lower upfront cost

100kW → greater generation, potentially greater exports

100kW + battery → different capital cost and load-management strategy

The best option depends on the business's tariffs, network conditions, budget and future plans.

This is an illustrative example—not a Liverpool customer result.

What Should the Commercial Solar Financial Model Show?

Before committing to a project, the proposal should clearly show its assumptions.

Look for:

If the savings calculation cannot show where its numbers came from, ask for more detail.
