Solar water heating system advantage and disadvantage
Answers
Advantages of Solar Water Heaters
The advantages go beyond cost savings and the availability of power, which are also realized with solar electric systems. Here are a few unique perks of home solar water heating products that may convince you to upgrade your home.
Disadvantages of Solar Water Heaters
Maintenance is one disadvantage, although most systems don’t require a high degree of care. However, scaling occurs when there are minerals suspended in domestic water, which build up as calcium deposits in the system. Adding water softeners or mild acidic substances such as vinegar can avoid scaling. It only must be done every three to five years, but this can vary depending on the water quality.
Corrosion is another concern. In open loop hydronic solar systems, oxygen can rust any iron or steel part. The plumbing components are more resistant if they’re made of copper, brass, bronze, stainless steel, plastic or rubber. Storage tanks should be lined with glass or plastic to resist corrosion as well.
Also, active systems can overheat if the size of the storage tank isn’t appropriate for the collector. The general rule is that for each square foot of collector, there should be 1.5 gallons of storage. With that in mind, such a disadvantage can be avoided.
Other disadvantages:
Compared to photovoltaic panels, solar thermal panels only heat water.
Solar heaters require sufficient roof space to accommodate them.
Solar water heaters require direct sunlight to function.
The system does not function on cloudy, rainy, or foggy days.
Annual maintenance is recommended to check the pump and antifreeze.
Installation requires the use of a new hot water cylinder.
