What is the first step in installing a solar thermal system?
Site assessment ensures the location receives sufficient sunlight and supports system components.
Why is proper roof anchoring important?
Correct anchoring prevents structural damage and ensures system stability during harsh weather.
Which PPE is most essential for rooftop installation?
Fall protection gear such as harnesses is critical to prevent injuries during rooftop work.
What ensures fluid flow in solar thermal piping?
Correct pipe pitch allows gravity-assisted or pumped flow of fluids without air blockages.
How should collectors be positioned for optimal performance?
Collectors should face true south (in the northern hemisphere) and be tilted at an angle equal to the latitude.
Which hazard is common during installation of solar thermal systems?
Falls from height, electrical shock, and burns from hot components are primary risks.
