When roof space is limited or not suitable for solar panel installation, wall-mount stands serve as a viable alternative. These stands are usually installed on south-facing walls (in the northern hemisphere) to ensure optimal sunlight capture.
Mounting Brackets
Often overlooked, mounting brackets play a crucial role in solar panel stand design. They securely attach the solar panels to the racking system, ensuring stability even in adverse weather conditions. Various types of mounting brackets exist, each suitable for different types of panels and installation setups.
Stand-Alone Solar Panel Stand
These free-standing structures are ideal for ground-mounted solar panels. Predominantly used in large-scale solar farms or when roof or wall mounting is not feasible, stand-alone stands offer the flexibility of positioning and angle adjustment for optimal sunlight exposure.
Delving into Solar Panel Stands / Racking Systems
Exploring the components of solar panel racking systems gives us a glimpse into their intricate design:
Roof Attachment
This component anchors the entire racking system to the roof, ensuring stability and security. It is designed to withstand heavy winds and other environmental forces. The type of roof attachment used often depends on the roof material and structure.
Clamps
Solar panel clamps come in various shapes and sizes, each tailored for a specific panel design or configuration. End clamps hold the solar panels at the ends, while mid clamps secure the panels in the middle. These clamps ensure a firm grip on the solar panels, preventing movement or displacement due to wind or other external forces.
Mounting Rails
These are the backbone of the racking system. They provide a sturdy platform on which the solar panels are placed. Mounting rails need to be resilient and strong, capable of bearing the weight of multiple solar panels for extended periods. They are usually made from aluminum due to its strength, durability, and resistance to rust.
Factors to Consider when Choosing Solar Panel Stands
Picking the right solar panel stand involves several considerations. Below are some key factors that you should keep in mind:
Adjustable Angles
Solar panels operate most efficiently when they are angled towards the sun. Therefore, stands with adjustable angles are highly desirable as they allow the panels to be repositioned according to the sun’s trajectory throughout the day and across seasons.
Space
The available space is a crucial factor in determining the type of stand to be used. If roof space is limited, wall-mounted or stand-alone solar stands may be considered. On the other hand, if there is ample roof space, rooftop solar stands may be the most viable option.
Durability
Given the long lifespan of solar panels, choosing a stand that is equally durable is a wise decision. Assess the materials, design, and construction quality of the stand to ensure it can withstand various environmental conditions for many years.
