Maintaining Solar Water Heating Systems

The development of green energy is as controversial as ever, but one thing you can’t deny is that – green energy is getting more and more efficient, and more affordable with every passing year. One of the main uses of this energy is implementing the technology of a solar water heating system.

 

Generally, solar water heaters require less maintenance. However, it’s necessary to check your solar water heater at least once a year to ensure all components are in top condition and to keep the system working perfectly.

Some of the components of solar water heating systems that should be monitored include:

1. Solar Collectors –

Solar collectors should remain un-shaded. It’s really common for solar panels that were in complete sun exposure when they are installed to receive shading due to tree growth. You may need to trim or remove vegetation.

Many states have their solar laws and regulations that protect the rights of a solar homeowner to maintain the solar accessibility for existing systems.

Dirt and dust particles can impact on the performance of collector. During dry, dusty weather condition, the solar panels may require cleaning periodically. Usually, snow and ice melt off on their own , but may require to be removed during heavy accumulations, if the panels are mounted at a shallow angle.

The solar collectors should be checked for yellowing or cracks. The seals can be checked to make sure they are still in good condition.

2. Roof and support 

Roof penetration should be checked on an annual basis to be sure there are no issues with water leakage. Both the nuts and bolts on racking systems should be inspected for tightness as well as racks are checked for signs of stress.

3. Pump 

It’s really necessary that the pump should remain in good condition as the pump failure can cause the solar water heating systems to overheat. The cold supply, high-pitched noises, return pipes are the best possible signs of a pump failure. If you find the pump is compromised, it should be repaired or replaced right away.

4. Controllers and sensors 

Both the sensors and controllers are the main part of the control system for your water heat. So it’s important that they should function properly. To check a sensor, apply mild heat. Remember, it should record the rise in temperature.

Many controllers come with digital displays that indicate malfunctions. However, you should check the unit by triggering differential – the temperature difference that the system is programmed. You can do this by apply heath and cold to the sensors until the system reacts.

5. Heat transfer fluid

Most solar water heating systems use a glycol solution. You should check the fluid annually to make sure it’s in good condition and should be replaced, if required. If you keep the system in a hard water area, the fluid should be treated to prevent scale.

6. Hot water storage tank

Hot water storage tank should be checked periodically for corrosion, leaks, or cracks.

While many of the parts can be checked by the user, some of them are best performed by a solar expert. Visit Website to know more information about solar water heating systems!
