Are solar hot water systems worth it in Perth?
Yes, solar hot water is worth it in Perth because Perth is one of the sunniest cities in Australia. Many homeowners and property owners already have a solar system, and solar energy can also be used for solar hot water.
Solar hot water systems use the sun's heat to warm water for daily life activities such as showering, washing dishes, and other household needs. It can be a practical way to use renewable energy for an important part of your daily energy use.
For many homeowners, investing in a solar hot water system is a long-term investment and provides benefits for as long as possible.
Replacing your old electric hot water system with a renewable solar hot water system is a great choice for you. It can help reduce your dependence on conventional energy sources and make better use of Perth's available sunlight.
The right size of a hot water system depends on your solar system size, location, and water usage. A properly sized system can provide enough hot water for your household without generating unnecessary costs.
How Does a Solar Hot Water System Work?
A solar hot water system uses sunlight to heat the water. A solar hot water system consists of a solar collector and a solar tank. The collector is installed on the rooftop where it can receive sunlight and use the sun’s heat to warm water. The heated water is stored in the insulated tank for later use. This stored hot water can then be used whenever you need it throughout the day.
A solar hot water collector directly uses the sun’s thermal energy to heat water. When there is plenty of sunlight and you still need hot water, an electric or gas booster provides additional heating.
The booster is more useful in winter, on cloudy days, or during periods of higher hot-water demand. It works as a backup heating source when the solar collector does not provide enough heat. This means homeowners can continue to get hot water even when sunlight is limited.
Can Solar Hot Water Reduce Electricity Bills?
Yes, solar hot water can reduce electricity bills by using sunlight as the primary energy source for heating water. A traditional electric heater uses the grid and increases the electricity bill. On the other hand, a solar heater primarily uses sunlight to provide warm water to consumers. This can help reduce the electricity needed for water heating and may yield greater energy savings over time.
The actual savings will depend on several factors, including:
How Much Hot Water Does Your Household Use
The type and size of your existing water heater
The solar hot water system you choose
The amount of sunlight available
Whether a gas or electric booster is required
Your electricity or gas prices
Installation and maintenance costs
The efficiency of the system
The number of people living in the property
What Are the Benefits of Solar Hot Water?
Lower Energy Consumption: Solar hot water reduces the conventional energy required to heat water, enabling homeowners to use more solar energy and save money. It can reduce the amount of electricity or gas required for daily hot water needs. This can also help homeowners make better use of the natural sunlight available in Perth.
Potential Bill Savings: Using solar hot water not only reduces the electricity bill but also reduces the amount of gas purchased for hot water. The amount of savings depends on your system and use. Households that use a large amount of hot water may have greater opportunities to benefit from an efficient system. However, the final savings will vary from one property to another.
Renewable Energy: Solar hot water uses energy from the sun rather than relying entirely on electricity or gas, helping reduce the environmental impact associated with conventional water heating. It allows homeowners to use a clean and renewable source of energy for their everyday hot water requirements. This can also support a more sustainable way of managing household energy use.
Long-Term Investment: Although solar hot water systems can have a higher upfront purchase and installation cost, the ongoing energy savings can make them worthwhile over the longer term. The Australian Government also recommends considering installation, maintenance, running costs, and available rebates when comparing hot water systems. Choosing a quality system and having it professionally installed can also help provide reliable performance for many years.
Works Well With Other Solar Technologies: A home can use different renewable-energy technologies together. For example, a property may have rooftop solar PV for electricity and a solar hot water system or heat pump for water heating. Using these technologies together can help homeowners use more renewable energy and reduce their overall dependence on grid electricity. The best combination will depend on the property's energy requirements, available roof space, and daily hot water usage.
