Scale Up, Win More: How to win a bigger share of the 100 kW to 1 MW surge

From 1 October, the SRES expansion lets systems up to 1 MW claim STCs at full capacity, up from 100 kW. For EPCs, that means a jump in mid-scale projects worth chasing, more tenders and sharper competition.

Join us for a free live webinar on how to turn around more tenders without adding headcount, and how to win the work with a defensible, value-stacked investment case that stands up to a CFO or investment committee. Includes a commercial site built live, from design through to a finished business case.

For C&I teams scaling up to take a bigger share before the rush.

Wednesday 23 September, 2026, 12pm (AEST).

SRES 1MW C&I Commercial Australia

Built for complex commercial projects

Commercial projects create bigger opportunities — but they demand more from your team. More variables to model, more options to evaluate, and a stronger business case to get the project approved.

Model complex systems with confidence

Model commercial tariffs, demand charges, solar, battery storage, generators and changing loads together, with the depth to confidently recommend the right system and operating strategy.

Move more projects through your team

Take more C&I projects through feasibility, design and proposal without adding the same amount of skilled labour. Automation and optimisation reduce repetitive work and let experienced designers focus where their judgement adds value.

Build a business case clients trust

Turn detailed energy modelling into a commercial case decision-makers can understand. Clearly demonstrate savings, payback, NPV, IRR and lifetime return for finance, procurement and management.

Feasibility and energy assessment

Assess the site’s energy position from meter data before any design begins.

Build the case on real data

SolarPlus reads interval meter data and builds load profiles that reflect real operating patterns. Energy costs are modelled in seasonal detail at your chosen timebase resolution, so the business case reflects how the site actually buys and sells power.

Import interval meter data in a broad range of formats, accepted down to one-minute intervals and across time range, then processed into reliable typical year format down to five-minute resolution.

Model commercial demand tariffs, time-of-use, net metering and net billing, with up to 144 rates and wholesale, network, retail and fixed charges kept separate.

Run 1000s of sizing scenarios in seconds to arrive at optimal sizing based on Net Present Value and chosen constraints. Detailed reporting and sensitivity analysis put you in an informed position from the start.

Build detailed load profiles with seasonal variation, duty cycles and surge analysis for modelling of off-grid and specific commercial loads.

Rebuild total consumption from grid-import data on sites that already have solar, with or without export data, so retrofit projects model without clean pre-solar records.

Bring in up to three years of market price history, or retrieve it directly for supported markets, then model everything from market-based tariffs through to price-based battery dispatch and VPP scenarios.

Design and electrical engineering

Streamlined design with fast panel layout tools, then build the full electrical design automatically to your rules.

Complex arrays designed in minutes

Auto-Design generates candidate electrical configurations, scores them on panel utilisation, stringing and inverter loading, and strings up the complete layout. Physics-based shade analysis runs in seconds on large commercial systems, resolved to diode-zone level across the typical meteorological year.

Design roof, tilt frame, back-to-back east-west, ground mount in one, two and three-up, reverse tilt, carport and vertical BIPV configurations.

Automatically set tilt, spacing, walkways, setbacks and row alignment across multiple roof faces, or for ground-mount layouts across commercial sites.

Model extruded obstructions, keepout areas and terrain to handle the rooftop and ground-mount complexity that commercial sites routinely present.

Ray-traced shading across a 3D scene, resolved to diode-zone level and visualised as a monthly-hourly solar-access table across the typical meteorological year.

Builds a complete electrical design from the panel layout, incorporating multiple surfaces, walkways, overcurrent protection and stringing options, fast and panel accurate. Duplicate with one-click and change inverter to produce a side-by-side comparison proposal.

Automated topology, protection placement and integrated cable design, fully editable (Beta), with connections that can be rerouted and exported as SVG.

Clear visual of MPP range, oversizing warnings, OCPR flag, battery arc-flash, and AC and DC cable voltage-rise and loss with warnings.

Model bifacial system performance based on view-factor comparable to SAM, showing bifacial gain advantage in the modelled yield.

Select panel render and generate engaging customer-facing 3D site tours. View shade at any time of year, export DXF of buildings, panels, trees and obstructions.

Arrays render on your own hardware: around 3 MW on a capable laptop and up to 8 MW+ on a high-specification desktop, with no licensing cap on size.

Energy and storage modelling

Model solar, storage, generators and smart loads together at five-minute resolution.

Size batteries that pay back

Size and set energy management settings with the ultimate Battery Optimiser, presenting best performing size and battery strategies including self-consumption, energy arbitrage, peak shaving, as well as hybrid combinations. Monthly setpoints and dispatch controls ensure maximisation of savings.

Five-minute modelling in the performance engine for accurate battery charge cycles, smart energy distribution and pricing giving maximum confidence in accuracy of the simulation.

Optimisation of energy arbitrage enhances RoI with automated mapping of grid charge setpoints across each month of the year to ensure peak and shoulder coverage.

Model grid-connect, hybrid, backup and off-grid systems in AC-coupled and DC-coupled configurations, with round-trip efficiency and conversions modelled on the DC bus to give full battery derating reports.

Run the battery sizing optimiser to quickly model the solar performance against a broad range of battery sizes, strategies and across exact tariff and loads settings. The result is fast drill-down to optimal size and management settings for best financial and self-sufficiency.

Full control over peak shaving effectiveness to offset demand charges. Monthly shaving and grid charge setpoints with state-of-charge and timing controls put you in control, with automation to provide the ideal settings.

Simulate worst-case multi-day outages and backup autonomy, and model a battery retrofit against existing arrays, or complement existing with a partial solar upgrade.

Coordinate solar, battery and generator dispatch on-grid and off-grid up to multi MW scale, with fuel-consumption curves, detailed reporting on runtime, before and after costing analysis, diesel displacement and grid connection comparison.

Model load shifting, EV smart charging and hot-water diversion hour by hour across the year in the Smart Energy Simulator, each costed against a before case and tariff-aware.

Financial modelling and lifetime returns

LCoE, NPV, IRR and lifetime cashflow that a CFO can sign off.

Numbers that stand up to scrutiny

Wholesale, network, retail and fixed charges are reported separately rather than blended into one saving, and lifetime modelling accounts for consumption change, price escalation, degradation, maintenance and finance across the full asset life. The reasoning behind every figure is transparent, so a procurement team or CFO can see how the numbers were reached and approve with confidence.

LCoE, NPV, IRR and year-by-year lifetime cashflow produced automatically for every design, ready to put in front of a commercial client.

Show the cost of doing nothing alongside the renewable case: rising electricity bills under business as usual set against export earnings, energy costs, finance and maintenance, with net annual benefit and accumulated savings year by year.

Wholesale energy, network, retail and fixed charges reported separately rather than blended into a single figure, so savings are traceable.

Account for consumption change over time, price escalation, solar and battery degradation, maintenance and finance costs across the full asset life. Compare lifetime energy cost with and without renewables to demonstrate long term value.

Treated as a lifecycle event, with replacement cost applied in the nominated year and degradation reset for the new asset.

Model cash, lease, rental, financed and PPA arrangements, with the lifetime return available at P90 as well as P50.

Include market export and trading revenue in the financial case for sites that participate in wholesale or market-linked arrangements where it applies.

Incentive and rebate schemes are modelled for the market the project sits in and applied directly to the financial case.

See how SolarPlus handles solar incentives and rebates including the SRES expansion for 100 kW to 1 MW systems and Australian state-incentive tools.

Proposals that make the business case

Turn the design into a proposal your client’s decision-makers can act on.

Give decision-makers a clear yes

Present the financial case in interactive online proposals or branded PDFs, with 3D fly-over tour, charts, side-by-side options that make the numbers easy to follow. Decision-makers can compare configurations, see the payback and lifetime return, then accept and pay online through card or finance.

Fully customisable, branded proposals in PDF or interactive online format, with charts, visuals and a hosted 3D walkthrough of the site.

Present several configurations for one site on a single customer-facing page, from which the customer selects one and continues to acceptance.

AI generated proposal narrative tailored for the specific audience and grounded in verified project performance and RoI data along with your added prompts. Compares proposal options to assist in decision making.

Card payment and finance integration on the acceptance page, with loans, leases and PPAs at adjustable term and deposit, and repayments recalculated automatically.

Track sales by user and status with daily, weekly and monthly breakdowns, plus cashflow projections and full historical sales reporting.

Quick Quote, pre-built system packages, upsell extras and a per-job profit-breakdown calculator, with the option to price to a target margin.

Delivery and install workflow

Carry the project through to install, commissioning and customer handover.

One platform, enquiry to handover

A built-in CRM tracks every sales and install touchpoint, and the install set covers job packs, Job Safety Analysis, connection diagrams and commissioning checklists. Business Personas and formula-based pricing keep a team consistent, and integrations connect SolarPlus to the accounting, CRM and finance tools you already run.

End-to-end tracking of every sales and install touchpoint, included on every plan so the whole job lives in one system.

Repeatable defaults for tariff, consumption profile and system package, set by market, team or project type to keep quoting consistent.

Automated pricing that responds to system size, equipment, mounting configuration and location, so quotes stay accurate as the design changes and providing confidence in profit margins.

Job-tracking dashboard, site packs, commissioning reports and owner handover manuals, generated from the design rather than rebuilt by hand each time.

Job Safety Analysis, install job pack, connection diagram, QR-linked site map and commissioning checklist, plus one-click generation of the System Handover Manual.

Orders and invoices with payments and Xero sync, plus integrations including HubSpot, Zapier, the Webhook API, Stripe, Smart Ease and Simpro.
