Degree of Over Shading
Shading will reduce the overall performance of a solar system. During the planning stage of a solar system. Con-
sid- eration should be given to the location of the collectors with the aim of minimising the effects of shading from
high buildings, trees, etc.
none / little / a lot
Collector Fixing Surface
Is there enough room for the solar panels to sit on the required roof?
(yes/no)
Is there enough between gulleys (top, bottom and both sides) to prevent leafs and debris from gathering
around the panels?
(yes/no)
Orientation of Roof & Estimated Tilt Angle of Roof for Mounting Solar Collectors
What is the Roof orientation (should be between East SE - West SW)
Collector should be facing the equator
Is an inclinded roof frame need to obtain required pitch?
(yes/no)
To calculate optimal angle of tilt multiple latitude x 0.7 for domestic hot water production
Birr 37.16°, Cork 36.3°, Dublin 53.43°

Location of Solar Pump Station & Solar Controller
Ensure the pump station is located in an area where it can be easily accessed for servicing & main- tenance
(Confirm)
Ensure that there is adequate space both left and right of pump station to allow easy access to remove pump
in future.
Ensure that the solar controller is located in an area that is easily accessible for the user
(Confirm)
Ensure that the controller is mounted at the ocrrct height for easy viewing.
(Confirm)
Existing Plumbing System
What type of plumbing system is in the dwelling (vented or un-vented)?
Is solid fuel incorporated into the plumbing system?
Is there adequate access to route pipe work from solar collectors down to cylinder location?
(yes/no)
Is there space in the hot press to locate solar pump station?
(yes/no)
