1. Initial cost: Solar water heaters may have a higher initial cost compared to conventional water heaters. This may discourage people from investing in them.
2. Installation issues: Solar water heaters may require additional space for installation and a space that is exposed to maximum sunlight throughout the day.
3. Weather-dependent: Solar water heaters rely on sunlight to heat water. In areas that experience heavy rain or cloudy weather, the efficiency of these systems can be reduced.
4. Maintenance: Solar water heater systems require regular maintenance to ensure optimum performance. The system needs to be cleaned, and the internal components must be serviced regularly.
5. Compatibility: Designs for solar water heaters may not always be compatible with the architecture of the building, which can limit the types of buildings they can be installed in and may add to the cost.
6. Limited storage capacity: Solar water heaters often have limited storage capacity, which means that the availability of hot water may be limited during periods of high demand.
7. Durability issues: Harsh weather conditions such as hail, high winds, and extreme temperatures can damage solar panels, reducing their lifespan and effectiveness.
8. Design and Aesthetics: Solar water heater designs and aesthetics can sometimes clash with traditional architecture styles. This can be a challenge in the case of historic structures or specific building codes.
