What design considerations does the builder need to take into account to accommodate a Solar Hot Water system?
A – It is best to contact KCP Energy and get input specific to your project. For a basic two panel residential install the following should be taken into consideration: 1. Roof requirements: • Typical installs use two 4’ x 8’ panels and are mounted side by side so sufficient space must be available on the roof. It is recommended to allow 12″ on each side of the panels. It is preferred if the panel area is clear of vents and stacks. • Roof orientation must be within 45 degrees of true south and not be subjected to excessive shading (a solar site survey can be completed by KCP Energy to assess the proposed panel location). • Roof loading typically is not an issue. Each panel weighs approximately 100 lbs. • For ease of panel mounting roof blocking should be mounted between rafters. • Roof pitch must be considered – preferred install method is flush to the roof. The minimum for flush mount is 4/12 (18 degrees) however 8/12 (34 degrees) or greater is preferred. • Most type of roof materials
