Solar Electric vs Solar Hot Water: Which is Best for Your Brisbane Home?
As Brisbane homeowners continue to embrace renewable energy, solar power has become a popular choice for many looking to save on energy bills and reduce their carbon footprint. When considering solar energy for your home, you’ll come across two main options: solar hot water systems and solar photovoltaic (PV) systems. Both systems harness the sun’s power but serve different purposes and have unique advantages.
At ASFLOW Plumbing, we understand that deciding between these two can be confusing. This guide will help you understand the differences between solar hot water and solar PV systems, so you can make the best choice for your home.
Solar Hot Water vs. Solar Electric: What’s the Difference?
Solar Hot Water Systems are designed specifically to heat water for household use. These systems use solar thermal panels installed on your roof. Water circulates through these panels, absorbing heat from the sun, which is then stored in a tank for your daily needs – from showers to washing dishes.
On the other hand, Solar PV Systems convert sunlight into electricity using photovoltaic panels. The electricity generated can power anything in your home, including your hot water system, lights, and appliances. These systems can be connected to the grid, allowing you to sell excess power back to your provider, potentially reducing your electricity bills significantly.
How Do They Compare in Terms of Installation?
Solar Hot Water Systems: The installation of these systems depends on the type you choose. A Hiline System mounts both the solar collector and the storage tank on the roof. It relies on natural thermosyphon flow, which can be efficient but may require a sturdy roof structure to support the weight. Alternatively, a Loline System places the solar collector on the roof and the storage tank on the ground. This option is often cheaper to install, especially for homes with flat roofs or limited space.
Solar PV Systems: These are typically simpler to install than solar hot water systems. PV panels are lightweight and can be mounted on most roof types with the correct mounting system. They convert sunlight directly into electricity, which is then used in your home or fed back into the grid.
No matter which solar option you choose, positioning is key. All solar panels should face north and be tilted at roughly a 20-degree angle to maximize exposure to sunlight. In Brisbane, where roofs are commonly pitched at 22 degrees, this setup is ideal. Remember, keeping panels free from shade and regularly cleaned will help maintain their efficiency!
Which Option Will Save You More Money?
When it comes to cost savings, both solar hot water and solar PV systems offer substantial benefits. However, for many Brisbane homeowners, solar PV systems are often the best choice. Here’s why:
- Dual Functionality: A solar PV system can power your entire home, including your hot water system. This dual purpose means more overall savings on your electricity bill.
- Feed-in Tariffs: Excess electricity generated by your PV system can be fed back to the grid, potentially earning you money or offsetting your electricity costs.
- Lower Installation Costs Over Time: With the costs of solar PV panels dropping in recent years, they have become more affordable, while the price of solar hot water systems has remained relatively stable or increased.
For homes already equipped with a standard electric hot water unit, switching to a solar PV system can be a seamless process. By installing a timer, you can ensure that your hot water system only heats during the day when your PV panels are generating power, maximizing your savings!
Choosing the Right Solar System for Your Home
If you’re looking to make your home more energy-efficient, a solar PV system that powers an electric hot water unit is a highly effective solution. This approach provides all the benefits of solar energy – from reduced bills to lower carbon emissions – while also covering your hot water needs.
However, if your priority is primarily heating water, and you have a roof that can support the extra weight, a solar hot water system could be the right choice.
