The GPS Professional Flush Mount Hardware Kits from DIY Solar Guide are the perfect low-cost, efficient, secure, made in the USA solar panel mounting hardware option. These kits are easy to install, easy to combine for longer solar panel arrays, and are sold below market cost just for our valued customers.
Each rail set includes a top and bottom rail in order to secure your solar panels at all 4 corners, as well as hardware for attaching the rails to your roof or other structure, and for attaching your solar panels to the rails.
To determine the correct rail length, simply follow the diagram and formula below.
- Length of Your Roof: ____________________
- % of Roof for Solar Panels: ____________________
- Multiply Line 1 x Line 2: ____________________
- Multiply Line 3 x 12 ____________________ (panel area width in Inches)
- Width of Your Solar Panels: ____________________ (inches)
- Divide Line 4 by Line 5: ____________________ (round to the lower whole number)
- Line 6 is the number solar panels per row that will fit in the area you have set aside for your solar array.
- Multiply Line 6 by Line 5: ___________________ (inches)
Line 7 is the exact width of the Solar Panel array rows. Now, all you need to do is find the pro-flush mount hardware kit that is the same length. If one length is not appropriate, you may add two kits of different lengths together to make the proper length.
- Please note, that a support that is a couple inches too long is okay, but a support that is even an inch too short is not.
