Introduction

Mounting your solar panel inclined to an optimized angle with respect to the horizontal 

axis can lead to increased annual collection of sunlight. Depending on the location and 

time of the year, this could lead to up to 50% more solar energy collection compared to 

horizontally mounted panels. Typically, for optimal annual performance, the solar panel 

should be tilted at an angle equal to 0.9 times the latitude of the location with respect 

to the horizontal. For optimal summer performance, the solar panel should be tilted to 

an angle equal to latitude – 15 degrees and optimal winter performance the solar panel 

should be tilted to angle equal to latitude + 15 degrees with respect to the horizontal.

The ADJ-28 Tilt Mount kit includes 4 Nos. sturdy 28” Aluminum mounting rails, 2 Nos. 

14” Aluminum brackets (Fig. 1) and stainless steel hardware required to securely fasten 

a solar panel to the roof of your Recreational Vehicle (RV) or any other flat surface. The 

inclination of the solar panel can be adjusted to a desired angle with respect to the 

horizontal axis.
