Can Aluminium Unistrut Handle Heavy Loads And Large Solar Panels?

Mounting solar panels and the support structure is a matter of choice. But the question is does aluminum Unistrut have what it takes to support heavy loads and large solar panels?

 

Aluminum unistrut strength in detail

 

Aluminium Unistrut is lightweight, corrosion-resistant, and easy to install. Therefore, it is the first choice for many solar panel installations. However, it is not as strong as steel Unistrut, which is often used in heavy-duty applications. The Aluminium Unistrut can bear moderate loads, but if the size of the solar panels is large or there are multiple-panel arrays, then its load-bearing capacity may be a problem.

Factors affecting load capacity

 

The ability of aluminum Unistrut from SM Solar to support heavy loads depends on the following factors:

 

·         Panel Size & Weight: Most residential panels weigh between 15 and 25 kg (33 and 55 lbs) each, and larger commercial panels can be much heavier. Installing several large panels will quickly increase the total load.

·         Span Length: The farther apart the supports are, the more stress is put on the Unistrut. Shorter spans offer better support.

·         Wind & Snow Load: Regions with high wind speeds or heavy snowfall require stronger framing systems to prevent bending or failure.

·         Mounting Angle & Bracing: A well-designed racking system with additional bracing improves load distribution and prevents structural issues.

 

Steel vs. aluminium: which is better?

 

If you’re dealing with heavy loads like a 12v Lithium Ion Battery or large solar panels, steel Unistrut is generally the better choice due to its higher tensile strength. However, if weight reduction, corrosion resistance, and ease of installation are top priorities, aluminium can still be a great option; provided it’s properly reinforced with additional supports.

How Does A 12v Lithium Battery Differ From A Lead-Acid Battery?

 

In terms of running your devices, vehicles, or indeed solar setups, the debate between using a 12v lithium battery and a lead-acid battery is a common discussion. Both batteries have merit for residential and commercial applications but differ in terms of performance, lifespan, and maintenance.

 

a)     Weight and portability

It is also heavy; the 12v 100ah Lithium Battery has obviously more weight compared to its counterpart, lead-acid. The disadvantage of this characteristic is that it is difficult to move with such a battery, especially during RV, boat, or bike electric cycling. Lead-acid batteries can be like carrying a sack full of rocks-not exactly a convenient item!

 

b)    Lifespan

 

For a long-term investment, go for lithium batteries. A 12v lithium battery from SM Solar lasts about 2,000-5,000 charge cycles, whereas a lead-acid battery lasts 300-500 cycles. With time, the lithium battery's durability will pay for itself, although the upfront cost is more.

 

c)     Maintenance

 

Lithium batteries are nearly maintenance-free. Once installed, you can pretty much forget about them (apart from charging, of course). Lead-acid batteries, however, need regular checks to ensure proper water levels and to clean any corrosion. If you're not a fan of extra chores, lithium is the stress-free option.

 

d)    Cost

 

Here is where lead-acid batteries have an advantage-they are cheaper upfront. However, when you factor in their shorter lifespan, higher maintenance, and less efficient performance, the initial savings might not feel so sweet in the long run. A 12.8v Lithium Battery may cost more initially, but it pays off in durability and reliability.
