Replacing a solar hot water tank? The options available depend on whether your solar hot water system is installed on the roof or the ground. Each configuration has its considerations, and the choice of replacement options may vary accordingly.

Roof Mounted Solar Hot Water System - replacement options are not limited to solar.

Solar Hot Water System – Roof Mounted

If your solar hot water system is installed on the roof, it typically consists of solar panels mounted on the roof that capture sunlight and transfer heat to a water storage tank above the panels via thermosyphon. When considering replacing the tank in this configuration, you need to consult with a qualified solar hot water system installer or technician. An assessment will be made as to the condition of your system, recommendations given about appropriate replacement options, and they can handle installation while adhering to safety standards and local regulations.

If your solar panels are in good condition and functioning well, you may choose to replace only the water storage tank. While this can be a cost-effective solution, there are many complexities to be considered. Access to the roof can be challenging, and potentially dangerous. Additionally, it may involve the use of a crane or heavy lifting equipment.

It is important to factor in the age of the tank and panels when considering replacement options. The solar panels and the solar tank are usually around the same age and stage of their life cycle and it can be more cost-effective to replace both at once.

In the replacement process, it’s worth considering other water heating options. Discuss all your options with a trusted plumbing professional to ensure you choose the best hot water system for your needs.

Solar Hot Water System – On Ground

Solar hot water systems installed on the ground typically have solar panels and water storage tanks located separately. When replacing the tank in this configuration, the process is less complex and can offer more options.

Similar to roof-mounted systems, you can replace only the water storage tank while keeping the existing solar panels and plumbing intact. Alternatively, you may choose to upgrade to a larger tank or a more energy-efficient model to meet your hot water needs while reducing energy consumption.

During the tank replacement process, it’s also a good time to assess the condition of your solar panels. If they are nearing the end of their lifespan or have significant damage, you should consider replacing them along with the tank.
