Australia Solar Sharer Offer: EPC Guide to Midday Power

What the Solar Sharer Offer Is and Why It Exists

The Department of Climate Change, Energy, the Environment and Water launched the Solar Sharer Offer for Australian households. The programme introduces a midday electricity incentive that encourages more solar generation during the day’s peak demand period. By shifting consumption to the middle of the daylight window, the scheme aims to reduce grid stress and lower overall electricity costs for participating households.

The incentive aligns with the government’s broader renewable‑energy targets, which call for increased solar capacity and higher self‑consumption rates. In the 2022‑23 financial year, peak grid demand between 11 am and 2 pm accounted for 28 percent of total daily demand, according to the Australian Energy Regulator’s 2023 Energy Statement. Targeting that window directly helps flatten the demand curve.

Before the Solar Sharer Offer, households could only benefit from the standard feed‑in tariff, which applied a uniform credit to all generated electricity. The new midday‑specific credit is a policy shift intended to boost generation when the network is most constrained, as outlined in the programme’s background notes on the official page.

Practical tip for EPCs: Highlight the midday incentive in early client meetings to position your proposal as a cost‑saving solution that leverages government support.

How the Solar Sharer Offer Is Structured

System Size and Capacity

The scheme applies to residential‑scale grid‑connected PV installations up to 10 kW. Installations above this threshold fall outside the incentive eligibility. This ceiling is listed on the official Solar Sharer Offer portal.

Geographic Coverage

The incentive is available nationwide, but some states issue supplementary guidance that may affect documentation or reporting frequency. State‑specific notes are published on the programme’s “State Guidance” page.

EPC Accreditation Requirements

EPCs must hold the relevant Australian standards certifications for solar installation, typically the Clean Energy Council (CEC) installer accreditation. The official programme page notes that only accredited installers may submit compliant designs.

Technical Performance Criteria

To qualify for the credit, installed systems must demonstrate a minimum of 5 kWh of generation during the 11 am‑2 pm window on at least 70 percent of days in a rolling quarter. This performance metric is defined in the programme’s technical specifications.

Key Dates and Application Deadlines for the Solar Sharer Offer

The Solar Sharer Offer runs on an intake basis, with application windows announced on the portal.

• Application opening: New intake periods are posted on the portal; EPCs should watch for the “Apply” button.
• Submission deadline: Each intake has a hard cut‑off; late submissions are rejected.
• Approval notification: Successful applicants receive electronic confirmation before installation can begin.
• Mid‑year review: The government may adjust incentive parameters; EPCs must stay informed to avoid non‑compliance.

Because dates can shift, EPCs are advised to set internal alerts for any changes posted on the official page.

Action Checklist for EPCs

• Verify eligibility: Confirm system size does not exceed 10 kW and that the client location is covered by the national programme.
• Secure accreditation: Ensure the EPC holds current CEC installer accreditation and can provide proof upon request.
• Model midday output: Use simulation tools to generate a “midday‑only” output scenario that meets the 5 kWh threshold.
• Prepare documentation: Compile the compliance checklist, system specs, and performance model for submission.
• Monitor portal updates: Subscribe to the Solar Sharer Offer news feed for any changes to thresholds or reporting schedules.

Design and Proposal Considerations for EPCs

To align proposals with the Solar Sharer Offer, EPCs should adopt the following design practices:

• Optimise tilt and orientation: Prioritise roof angles that capture the sun’s highest irradiance between 11 am and 2 pm.
• Incorporate modest storage: Small battery packs can shift excess midday generation to later periods, further reducing grid reliance.
• Select inverters with midday‑focused algorithms: Modern inverters can maximise output during the incentive window.
• Model customer load profiles: Use realistic consumption patterns to demonstrate how the incentive reduces net imports.
• Document compliance: Include a dedicated section in the proposal that maps each system spec to the programme’s technical criteria.

Design guidance: Use simulation tools that allow you to run “midday‑only” output scenarios, then embed those results in the proposal’s financial analysis.

Economic Impact: How Midday Electricity Changes Project Viability

A midday electricity incentive reduces the net amount of electricity that a household must purchase from the retailer during peak hours. This reduction improves the overall economics of a solar project by lowering the levelised cost of electricity for the end‑user. The Clean Energy Finance Corporation’s 2024 financing outlook notes that incentives that cut household electricity purchases can shorten payback periods by 1‑2 years on average for residential PV systems.

When drafting proposals, consider the following levers:

• Increased self‑consumption: Designing for higher midday output directly translates to lower grid imports.
• Potential for ancillary services: Some utilities may reward excess midday generation with feed‑in tariffs or capacity payments.
• Financing appeal: Lower operating costs improve cash‑flow projections, making projects more attractive to lenders and investors.

While exact financial figures vary by location and utility rates, the principle remains: any mechanism that reduces household electricity purchases strengthens the business case for new solar installations.

Compliance, Reporting and Risk Management

Compliance obligations are detailed on the Solar Sharer Offer website.

• Reporting: Submit periodic generation data as specified by the programme, typically on a quarterly basis.
• Performance verification: Allow auditors to access system performance logs to confirm that midday output meets the incentive criteria.
• Documentation retention: Keep all installation records, certification documents, and client agreements for at least five years.
• Risk mitigation: Incorporate clauses in client contracts that address potential changes to the incentive structure, ensuring cost recovery if the programme is altered.

Adhering to these steps secures the incentive for the homeowner and protects the EPC from regulatory penalties.
