With the rising cost of living in Australia, Aussies are doing their best to keep household bills as low as possible. Installing solar panels to heat household water is a strategy that many Australians use to keep their energy bills down. However, simply installing solar panels does not guarantee efficiency. You need to maximise solar heat absorption on your panels to feel the impact of your investment. This article highlights ways to maximise solar panel heat absorption.

Solar Panel Tilt Angle

When you need hot water on demand, you must think about the installation mode of solar panels. Ideally, the optimum solar panel installation angle is perpendicular to the sun. However, the sun changes its position throughout the day, meaning that installing solar panels at a fixed angle does not maximise solar heat absorption. It is the reason motorised solar panel installation is the best option for maximising heat absorption.

As the name suggests, motorised solar panels are installed on a rotating platform equipped with sensors. It allows solar panels to track the sun's path throughout the day, ensuring maximum solar heat absorption. It means that you can have enough hot water in your tank within a few hours. Motorised solar panels are best suited for flat roofs. However, you can install motorised solar panels on the ground if your house features a pitched roof.     

Solar Panel Size

Solar panels come in varying sizes, and the type you choose is a matter of preference. For instance, if your house has limited roof space, small solar panels are the most suitable. However, do not expect a small solar panel set up to provide a multi-generation family with enough hot water even when the sun shines the whole day. The reason is that solar panels with a limited surface area do not allow you to leverage the amount of solar heat available. Large solar panels are excellent at maximising solar heat due to the large number of photovoltaic cells available per square inch. It ensures that solar panels trap every little bit of solar heat available for maximum water heating.

Solar Panel Position

Most people know that solar panels are installed on either the roof or the ground. However, what happens when only one side of your house receives adequate sunlight and you do not have enough ground space? In such situations, you can maximise solar panel heat absorption by installing a few devices on a roof and the rest on the walls. Vertical solar panels compliment the roof panels, especially if you install them on the West or East-facing walls. If you position your solar panels strategically, you will not have a problem trapping as much solar heat as possible.
