Common Components of Your Energy Bill Post Solar:

For many Australians taking the leap into solar energy, understanding the various components of the post-solar energy bill is paramount. Here’s a breakdown of what you might find:

• Consumption Charges: This pertains to the cost of the energy you’ve consumed. Even with solar panels, you might still draw some power from the grid, especially during evenings or cloudy days.
• Daily Supply Charge: Regardless of how much energy you use or produce, this fixed charge covers the cost of being connected to the electricity grid.
• Feed-in Tariff Credits: When your solar panels produce more energy than you use, the excess is sent back to the grid. This energy earns you credits, thanks to feed-in tariffs.
• Service & Additional Fees: Any other charges or fees, such as those for maintenance or service calls.
• Solar System Financing: If you’ve financed your solar system, details of the loan or payment scheme might appear on your bill.
• GST: The Goods and Services Tax applied to your energy charges.

One-Off Charges That Sometimes Form Part Of Your First Bill

In Australia, there can be one-off fees associated with getting a solar system connected and integrated into the energy grid. These fees largely depend on the energy retailer and the distributor in the specific region, as well as the size and type of the solar installation. Here’s an outline of potential one-off fees a homeowner or business owner might encounter:

1. Connection Application Fee: Before installing a solar system, an application to connect to the grid is typically required. Distributors might charge a fee for processing this application.
2. Metering Charges: After the solar system is installed, the existing electricity meter might need to be replaced or reconfigured to measure both the energy consumed from the grid and the solar energy fed back into the grid. There might be charges associated with this metering change.
3. Inspection Fees: Some distributors may charge a fee for inspecting the solar installation to ensure it meets the necessary requirements and standards for grid connection.
4. System Size Upgrade Fee: If a homeowner decides to upgrade their system size in the future, there might be additional fees for changing the connection agreement.
5. Export Limitation Fee: In some regions, there might be a need for an export limitation device to ensure the solar system doesn’t feed excessive energy back into the grid, potentially destabilising it. If required, there could be a fee associated with setting up this device.
6. Grid Protection Fee: In areas where the grid might be sensitive to additional solar connections, there could be fees for additional grid protection equipment.
7. Solar Buyback Scheme Setup: If the energy retailer offers a feed-in tariff or a solar buyback scheme, there might be an administrative fee for setting this up on the homeowner’s account.
8. VPP (Virtual Power Plant) Setup Fees: Virtual Power Plants (VPP) are becoming more popular in Australia. A VPP is a network of decentralised, medium-scale power generating units such as solar PV and battery systems. Homeowners can opt to join a VPP, allowing them to not only generate power for personal use but also supply the grid during peak times or when there’s high demand. Joining a VPP might involve integration costs, management fees, battery compatibility check fees, and communication equipment fees.

If you have a charge that youre not sure of, speak to your energy retailer who can explain what it is, what it means and why it has been charged – plus if it’s one-off or a recurring charge.

Common Issues & Misunderstandings With First Post-Solar Energy Bills

Embracing solar energy is an exciting journey towards both sustainable living and potential cost savings. Yet, as with any new venture, there can be a learning curve. When Australian homeowners get their first post-solar energy bill, it might look a bit different than expected.

Let’s address some of these common queries and set the record straight:

Partial Billing Period:

Many homeowners anticipate their first bill to showcase a full month of solar savings. However, if your solar panels were installed partway through the billing cycle, your bill will likely reflect just a segment of the solar energy generated during that period.

Estimated vs Actual Readings:

Some energy retailers send bills based on estimated readings vs actual meter readings – so if your first bill post-solar is based on an estimated reading – they may have calculated what energy they expect you have used, without taking into account the drop in energy usage due to solar. This should correct itself with a much smaller or negative bill once an actual reading is taken.

High Peak Power Usage:

It’s easy to expect a sharp decline in electricity costs immediately after your solar installation. Yet, without aligning your energy habits to solar production times, you might continue drawing power from the grid during its peak hours, resulting in unexpected charges.

Feed-in Tariffs:

While homeowners often look forward to a stable feed-in tariff rate for the surplus energy returned to the grid, it’s crucial to understand that these rates can fluctuate. Additionally, there could be restrictions on the volume of energy one can send back to the grid.

Solar Production Variability:

A common assumption is that solar panels will consistently deliver energy at their maximum capacity. However, various factors, including weather conditions, the changing seasons, and potential shading, can influence the actual solar output.

Changing Energy Consumption Patterns:

The notion that solar energy is “free” can lead some to ramp up their energy usage after the installation. This mindset, particularly if consumption occurs during non-solar peak hours, can increase reliance on grid energy and consequently elevate bills.

One-Off or Initial Charges:

Receiving your first post-solar bill, you might be startled by unforeseen charges. Remember, certain one-off fees might be tied to the integration of your solar system into the local grid.

GST and Other Charges:

When assessing their bill, some might overlook the GST or mistakenly assume all costs are directly linked to their solar system. Yet, GST is applied to multiple parts of your energy invoice, and regular service or maintenance charges remain applicable.

Solar System Financing:

Overlooking solar financing agreements when reviewing the bill is a common oversight. If you’ve chosen to finance your solar system, periodic loan or payment details will be reflected on your invoice, affecting the total due.

Battery Storage Misconceptions:

Opting for battery storage often gives homeowners the impression they’ve gone entirely off-grid. However, the reality is a bit different. Even with a battery in place, there will be instances, especially during extended cloudy or rainy spells, where drawing power from the grid becomes necessary.

Net vs. Gross Metering:

The difference between net and gross metering can be confusing for many. While one might anticipate both to have similar billing practices, they don’t. Under net metering, homeowners are billed for the electricity they consume minus the solar energy they produce. In contrast, gross metering involves selling all generated solar energy to the grid, with homeowners then purchasing back what they need. The two have distinct billing implications.

Non-Solar Friendly Energy Providers or Plan:

A common misconception is that all energy plans or providers offer identical solar incentives or rates. However, making a switch in your provider or plan can influence your feed-in tariffs and other solar perks. It’s always advisable to do thorough research or seek advice when considering a change.

Frequently asked questions about first bills
