Many home appliances consume a high amount of energy, which can drastically increase electricity bills. Fortunately, you can reduce electricity costs by cleverly using some home appliances on solar energy.
However, a standard 4kW solar panel daily creates 16kWh of solar energy, but an average Australian household uses 10kW or 6570 kWh of electricity daily. Considering this, you must be savvy in selecting which home appliances can be used on solar panels.
This guide will discuss which appliances can be powered through solar energy to efficiently lower your electricity bill.
Let’s take a look at what appliances can run on solar power.
1. Washing Machine
Using solar energy to power your modern washing machine is an energy-efficient option. However, it’s important to note that the hot water setting on the machine requires more power than the cold water option. This is because additional energy is needed to heat the water.
For optimal energy savings -and to prevent clothes from fading, it is recommended to use the cold water setting for every wash. Doing so can conserve energy and keep your clothes looking vibrant for longer.
Clothes dryers use between 1.6 kWh to 5 kWh of electricity to dry clothes efficiently. Since these appliances require less power, using solar energy to dry clothes can be inexpensive.
If you plan to buy a new clothes dryer, consider a condenser over a vented dryer. Condenser dryers are known for their higher energy efficiency, as they collect and reuse hot water vapour from the air. This feature reduces energy consumption over time, helping you save on your energy bills and reducing your environmental impact.
The amount of solar power needed to run your dishwasher depends on its size, as larger dishwashers require more energy. However, if you run the dishwasher during peak sunlight hours, the solar panel system can power it efficiently.
It is advisable to avoid using the dishwasher at night, as the solar batteries may not have enough stored energy to run the dishwasher and power the house simultaneously. Therefore, it’s best to use the dishwasher during the day to ensure optimal energy usage and efficiency
4. Pool Pump and Filter
According to a 2018 study, approximately 2.7 million Australians have a swimming pool at their homes. If you are part of this statistic, then you likely use a pool filter to eliminate dirt and debris from the water. You may also use a pool pump to circulate chlorine in the water and push debris out through the circulation system.
Pool filters and pumps are more frequently used during the summer when the pool is used more commonly. However, constantly running this equipment can lead to a significant increase in your electricity bill. On average, these systems require 2,000 to 3,000 kWh of power. Depending on your location and panel system size, your solar system may generate this amount during peak hours.
To maximise energy savings, you can directly connect the pool pump and filter to the PV system and remove it from the electricity grid. Alternatively, you can install a timer on the pump and filter to ensure it only runs during midday when enough solar power is available. These energy-saving steps allow you to enjoy your pool without worrying about the added electricity costs.
You can’t rely on peak hours to power your fridge and refrigerator with solar energy since they operate continuously throughout the day. Instead, you need to calculate their daily power requirements. Typically, a standard fridge consumes around 1.5 kWh per day.
By multiplying the total wattage of your solar panels with the daily sunlight exposure, you can determine how much energy your PV system generates. If your solar panels generate enough energy and you have sufficient battery storage, you can shift your fridge to solar power. Alternatively, you can use solar power during the day and switch to the electricity grid at night.
6. Air Conditioner
Air conditioners (AC) are one of the most important appliances to survive the sweltering heat of Australian summers. Since your comfort solely depends on an AC system, your electricity bill is bound to go through the roof. However, you can cut down on your expenses by running a solar-powered AC system.
A small AC unit requires 3.5kWs to reach the set temperature and 1.7Kw consistently to maintain it. If you have a 4kW solar panel system, it can easily cover the energy requirement between 9 am to 3 pm. You can connect the AC to the grid at night, as an extensive battery system supports the AC throughout the night.
7. Electric Oven
An electric oven draws a lot of energy to heat the appliance and maintain the cooking temperature. Considering this, your solar panels should generate more than 4 kWh to support electric ovens. Unfortunately, you can only use electric ovens on solar energy during daylight hours, as they require consistent energy that is impossible to get from battery storage.
What Factors Influence Solar Energy Usage?
There are certain factors that determine whether your solar panel system can power home appliances, which are:
- Solar Panel System Size: A large solar panel system produces more power than a small one, and it is more suitable for running home appliances.
- Region: PV systems generate more power in areas with more daylight hours and sunshine.
- Power Requirement: All appliances need a different amount of energy to operate. Solar power appliances, or appliances that require less energy, are more easily supported by the PV system.
Solar panel systems are a cost-efficient way to power home appliances throughout the day and lower your electricity bill. You can use your PV system to support the fridge, AC, dryer, electric oven, and other electrical devices. However, you should check the energy requirement of each appliance to ensure your solar panels produce enough energy to support them.
When running home appliances on a solar panel system, make sure to use them during peak hours, as the solar panels generate maximum energy at this time. You can even discuss using appliances on solar panels with your installation company. The experts at Solaire Connect can answer all your queries related to solar power systems.
