This also includes thepossibility of connection on the opposite side of the flat solar panels in each case.– The connection on opposite sides is recommended by DAIKIN (possible from 1 flat solar panel upwards).– Alternate side connection is acceptable for both DAIKIN Solar system systems ( + ).3.3 Laying connection pipesInstallation instructions concerning differences between unpressurised and pressurized systemFig. 3-2 Installation instructionsFor Solar panels on-roof installation of the flat solar panels, the roof surface must be inclined at an angle of15° to 80°.The flat solar panels EKSV26P and EKSH26P can be installed on flat roofs. Further information can be foundin the installation instructions for the DAIKIN Solar system flat roof framework.The flat solar panels EKSV21P and EKSV26P can be integrated into the roof surface. Further information canbe taken from the DAIKIN Solar system in-roof installation instructions.Fig. 3-1 Alternately connected Solar system solar panel with hot water storagetank EKHWP* (shown in the drain-back system ).Non-pressurised system (Drain Back) Pressurised systemWith solar panels connected at opposite ends, the wholesolar panel array must be set up with at least 0.5 %gradient to the lower panel connection (return flow).The connection pipe must be set up with a continuous gradientof at least 2 % and without any counter gradient.No particular minimum gradient of the solar panel array isrequired. A gradient from the lower (return flow) connectionshould however be avoided.The connection pipe between the solar panel array and the hotwater storage tank must be made of pressure-resistant metalpiping (CON XP16 / CON XP20 or Cu Ø 22 mm). Using plasticpiping is not allowed. |
