Like every other systems in your home, solar hot water systems will require periodic inspections as well as a regular maintenance in order to keep it running as efficiently as it should. Not only that, the various components will also require either repair or replacement from time to time. It’ll also be proactive to take the necessary precautions so as to prevent worrying issues like corrosion, scaling or freezing.
Is it a task you can handle on your own? Well, there are some inspections and maintenance activities you should be able to handle on your own, however, you’ll also require a qualified technician to carry out the more technical or complicated tasks. You should also take note that it may actually be more cost effective to have some systems replaced, shut off or removed completely than having it repaired. Here are some of the essential inspections that should be carried out on solar system components. They include:
✓ Collector soiling. Periodic cleaning of your collectors is important especially in dry and dusty climates.
✓ Plumbing, ductwork and wire connections. Check the pipe connections for fluid leaks. Examine duct connections and seals. Also make sure that all wire connections are tight.
✓ Roof penetrations. Flashing and sealant around the roof penetration should be checked to see that it’s in a good shape.
✓ Collector shading. Check for shading of the collectors on annual basis as this may greatly affect their performance.
✓ Support structures. Examine all bolts and nuts which connects the support structures to the collectors for tightness.
✓ Heat transfer fluids. Anti freeze solutions in liquid solar heating collectors will have to be replaced periodically. And this right here is a task that’s best handled by a licensed technician.
