Solar mounting structures consist of posts, crossbeams, braces, and connectors, and are classified as ground-mounted or rooftop systems based on their installation location.
I. Basic Components of the Mounting System
A full sun power fix thing for roof often have these parts:
Uprights: These are the up parts of the mount thing. One end fix to the base, the other hold the top bars. Uprights move the sun panel weight and the mount stuff down to the base.
Crossbeams: They put crossbeams at top of posts and set them flat. Solar panels get put on crossbeams, sometimes direct, sometimes not direct.
Braces: Braces are help parts that join the posts and crossbeams. They make the whole mount system more stable and stop shape change from wind push.
Fasteners: Things like bolts, clamps, and angle brackets, they use to hold all the parts together.
II. Common Types
By where you put it, solar mount systems split into two big kinds: ground put and roof put ones.
Ground systems put on ground, big use pile or concrete base, and good for big sun power plants.
Rooftop things are put on building tops, need think about roof's weight hold power and water proof needs; they often have light weight design.
Depending on if tilt angle can change, mounts can be classed as fixed ones and ones you can change. Fixed mounts angle stay same after put in place; they have simple build and less money cost. Adjustable mounts let tilt angle be changed for different seasons to make power get better.
III. Material Selection
Solar mounts mostly made from hot-dip galvanized steel or aluminum alloy. Hot-dip galvanized steel have big strong and less cost, so good for big projects. Aluminum alloy is light and not easy to rust, so good for roof places or where weight is a problem. All stuff need have good rust fight, 'cause mounts stay outside for long time.
IV. Performance Requirements
A good solar mount system need meet these things:
Strength needs: The mount thing must hold up the sun boards weight, wind push, snow push, and build push without break.
Stiffness Rules: The mount part's shape change under weight must stay inside okay limits to not mess up solar panels' normal work.
Durability stuff: The mount thing's design life is usually 25 years or more; stuff must have real good anti-rust and anti-old power.
