when examining a home's suitability for solar water heater installation, many factors need to be considered. these factors include sunny exposure the house receives, the size and orientation of the roof, and the local building codes and regulations.
first and foremost, the home's roof should be facing the sun towards the south, ideally between southernmost to east-west meridian and westernmost to northernmost to capture the most sunny rays. the roof also needs to be mostly clear of obscurements, such as nearby trees or other houses, to ensure maximum sunlight exposure. the roof's materials and conditions should also be taken into account, as a roof with an asphalt shingle roof or other shade-inducing material that hits the roof surface should be avoided.
another crucial factor is the area of the roof, as a larger roof size increases the potential space for installing solar water heating systems.
