RESIDENTIAL PV MOUNTING BASICS

Residential PV mounting comprises of several steps such as

  • Selecting the photovoltaic array’s location
  1. Consider protecting solar panels from unnecessary exposure
  2. Consider mounting in such location which is convenient for regular maintenance
  3. Consider minimizing the power loss by minimizing the length of the conductor to go to power conditioning equipment such as inverter, charge controller etc.
  • Securing the solar panels

This is an important factor, for your safety and as the solar panels are expensive, light weight, compact and thus vulnerable to theft. Protection system can be installed- specialized screws, padlocking the interconnecting mounting channel to the permanently mounted support frames etc.

  • Selecting a simple, strong, durable mounting system

Weather resistant, corrosion free materials should be used. Common choices – anodized aluminum galvanized steel, stainless steel etc.

1. First, find a structure to put a mounting system – roof of the house, ramada, cottage, and other customized ground structures, poles etc. Depending upon the structure used the mounting can be generally classified as follows

i. Roof Mounting

In general, roof mounting system, consists of rails carrying rows and columns of modules. The rails are connected to the roof via the fastening elements such as L-foot, stand- offs etc. The solar modules are clamped to the rails by middle and end clamps.

ii. Ground Mounting

For ground mounting, the rails are connected to the ground structure via different fastening elements such as brackets etc.

iii.       Pole Mounting

For pole mounting, the rails are connected to the top of the pole or side of the pole via different fastening elements such as brackets etc.
