Lesson 1.2 – Hardware considerations before ordering
The piping is attached to the panels through a series of patented clips, thus eliminating any need for drilling or glue. RST CleanTech provides about 20 different sizes of clips, depending on the type of solar panels used. Just specify the type of solar panel used, and a package of correctly sized clips will be included in the order.
To get an idea on how many clips, fittings, and sprinklers to include in the order, you’ll need to specify the number of solar panels in your array.
The other main consideration for residential installations is how to affix the valve control box to the wall. If the wall is concrete, you’ll need a 3/8 concrete drill and 3/8 concrete anchors. For wood, thin stucco, or similar material, you can use self-drilling screws. This is covered in detail in section 5.
