Installation Dilemma / Too many panels

    Turned out the SEAI guy who came out to me knew a friend of mine so I got into a decent enough conversation and was shooting the breeze about some of the requirements. I did bring up the 500mm spacing and it was indeed for wind loading. The danger is as you get closer to the edge there is a higher percent change that (turbulent) air will catch the panels, depending on what angle the wind is hitting the side of your house.

    Why 500mm, well they have to put "some" number on it. The risk of course is lessened the more you go, but 200-300mm and a well installed bracket correctly screwed/bolted into the rafter.....that guy ain't going nowhere.

    this is an interesting thread for sure. I lost out on 2 panels due to the 500mm rule. I am wondering about moving to 300mm post inspection and then adding another string. I honestly think 500 is excessive.

    Well the fact that they say 200mm away is fine from the ridge but not the side/bottom edge of the roof is a bit self-contradicting.

    I definitely missed on 1-2 extra panels because of it but the installer also said he wouldn't be comfortable with going so close to the edge so I took his advice.

    The only reason an SEAI installer would be uncomfortable going so close is that if they got an inspection, their install wouldn't pass the SEAI criteria for the grant 😂

    "Evidence array is not minimum 500mm from roof edge Evidence of no rail overhang to module and clamp Evidence of no end caps on mounting bar "


    What's needed for proof is a "Photo of array":


    STEP 2 Common Photos are required to confirm the location of the home and the works have taken place. The common photos shall be taken in three stages: A. Pre-install B. Post works C. During works - Please Note this applies only to the following measures; I. External wall insulation II. Internal wall insulation III. Floor Insulation Photos Required in all installations, 1. Front of the home 2. Both Sides elevations/Gables of the home (if applicable) 3. Rear/Back of the home 4. The ESB meter, this is to confirm the MPRN number and year of build 5. Gas Meter (if applicable)
