Why are you being Charged for Grid Consumption with Solar?

I thought that if I had solar, that I wouldn't pay another grid energy bill again?

Unfortunately, if you don't have a battery, your night time usage will be dependent on grid electricity as your panels aren't producing at these times.

Even if you have a large system with lots of exports during the day, your peak consumption may overrun the savings you earn back throughout the day. This greatly negatively impacts properties which consume most of their power during peak periods, as even the biggest solar system won't offset energy at night.

But I use most of my high-consuming appliances through the day when the sun is out? This will likely be offsetting the usage at night, saving you money. By being connected to the grid, you will also have to continue paying grid connection fees.

1. Reduction to your Feed-in Tariff (FiT):

The Feed-in Tariff is the credit rate at which energy retailers will pay for every kWh of energy that a customer’s solar system feeds back into the grid. Many energy retailers were offering generous FiT rates in order to attract solar customers to their service. However, over the past year, these benefits have greatly decreased across many electricity companies. Customers who could have been receiving up to 21 cents per kWh last year may now be receiving as little as 5 cents per kWh. Hopefully, this is set to change soon. 

If your energy bills have gone up recently despite your property having solar, check your energy bills to see the FiT rate you are now operating at.

2. General Electricity Price Rises

During 2023, there were two major price rise events for the electricity market. These may have initially gone unnoticed for solar customers receiving a good FiT, but with the combination of a lower FiT and skyrocketing grid energy prices, any excess energy that homes are drawing from the grid will be charged at an exponential rate. This is likely contributing to increased bill costs.

The best solution to this issue is the installation of a solar battery system, which will greatly reduce grid reliance and protect you during power outages. 

3. Higher Energy Use Since Solar Installation

Many customers assume that installing solar gives them a free pass to use a lot of power. And, to an extent, this is true.

However, if you have upped your energy use since installing solar, you may be exceeding the amount of power produced by your solar system and therefore incurring significant cost.

If you suspect this may be the case, there is a simple way to find out. Compare a recent energy bill that includes your solar system to a bill that you incurred before installing solar. Specifically, compare the peak and off-peak energy consumption between both bills. If you are consuming more energy in the period after installing solar, this is likely contributing to your bill price. This can be rectified by managing your energy use.

4. Consuming Energy at Night

Without battery storage, energy produced by your solar system can only be used during daylight hours, when the photovoltaic system is energised. If you have an unusually high bill, you may need to consider the times at which you use high-energy appliances in your home. For example, running your dishwasher, washing machine and air conditioner during night hours will be drawing lots of electricity from the grid, and therefore incurring cost. 

If you are reluctant to install a battery system at your home, you will need to consider using these kinds of appliances during peak daylight hours to reduce your energy bills. 

5. Bad Weather

If all previous options don’t seem likely, a higher energy bill at a home with solar could be explained by a particular bad month of weather. Though solar panels are still energised on cloudy/rainy days, they do not nearly produce to the extent of clear and sunny days. Consider whether the month has been affected by prolonged poor weather. 

6. Retailer is Unaware of your Solar

When solar is installed at your home, the installer is tasked with notifying your energy retailer of the extent and compliance of the system that has been installed. They then request that your energy retailer change either the physical metering or simply the energy plan that your property operates under so that your bills will reflect the particular FiT offered by the retailer. 

Elite Power Group takes pride in ensuring that this Service Works Request (SWR) procedure is completed in full and to the satisfaction of our customers. However, if you are unsure if your installer has undertaken this on your behalf, double-check that your energy bills include a solar FiT section. Contact your retailer ASAP if this appears to be missing from your bill, as you are not receiving the full financial benefits of your solar installation. 

7. Solar System Failure

This is the final and most unlikely situation. Solar systems are highly durable and simple to troubleshoot, so the likelihood that your bill price is due to a system failure is low. Elite Power Group prides themselves on high quality workmanship, however we are also committed to hearing our customers and rectifying any issues that may arise in our systems. 

Your installer should have access to online monitoring of your solar system. If you suspect your solar system may have issues - after considering the former reasons why your bill might be inflated - reach out to your solar installer to check if this is the case.

On-Grid vs. Off-Grid Fees and Costs

Solar is a great renewable solution to high energy costs. Importantly, there are two types of solar/battery solutions: On-Grid and Off-Grid.

Off-Grid means that your property has been completely disconnected from the electricity grid, relying solely on solar, battery, and generator energy to power the residence. These properties don't have to pay energy service and connection fees.

Because homes are still connected to the grid, even properties that are a Microgrid or Virtual Power Plant will still need to pay for service and connection fees.
