A well-installed and well-maintained solar water heater system can provide hot water for years to come, reducing utility bills, and reducing carbon footprint. However, for a solar water heater to perform well over the long-term, regular maintenance is necessary.

Impure or blocked solar panels can reduce the efficiency of a solar water heater system, making it harder for the system to heat hot water. Collectors must be cleaned promptly to remove accumulated dirt and dust. This can be done by inspecting the collectors monthly for signs of dirt or debris accumulation and cleaning them off with a soft-bristled brush. For more persistent buildup or clogs, a mild cleaning product with a soft-bristled brush may be needed.

In addition to system cleanliness, the system's pipes and connections should also be scanned for blockages or issues. Poor system performance can lead to costly repairs and lead to expensive repairs. For pipes and connections, consider using thermostatically controlled heat cables to prevent freezing.

Insulation can be an issue in some solar water heater systems especially if the storage tank is located in a poorly insulated area of the home. Examining the insulation of the storage tank and taking steps to improve them can ensure the system operates efficiently. Checking the insulation levels of the storage tank and taking steps to improve them can prevents energy loss. This can help maintain system efficiency and prevent temperature fluctuations that can damage the system.

It's also vital to track system performance over the long-term. Examining the system's performance indicators such as temperature readings, flow levels, can detect system issues early on. If significant changes in system performance are noticed, it's best to consult a professional.

Finally, consider having a professional inspect and maintain the solar water heater system at least annually. This can help identify potential problems and ensure the system continues to operate at peak performance. Regular maintenance and inspections not only save homeowners money in the long run but also reduce carbon footprint by maintaining system performance.

While solar water heaters are an excellent option for homes seeking to reduce their environmental impact, system upkeep is vital to ensure they continue to provide reliable service over the extended period. By pursuing system upkeep, solar water heater systems can last for 20 years or more providing hot water for generations to come
