Rail Mounting System

Rail Mounting System for Solar 

You may probably know that the two main types of solar installation are ground-mounted and rooftop-mounted solar installations. You may also learn the two basic kinds of ground-mounted solar systems, so now you are curious about if rooftop-mounted systems also have different ways to get it done. To tell you this, the rooftop solar installation can be also done in two ways. You can choose rail-mounted or rail-less solar panel installation. Between the two variations, the most widely used method is the rail mount.

In today’s article, we will briefly discuss what is rail mounting system is, its pros and con, and anything you should know before choosing a rail mounting system. 

What is Rail Mounting System?

A rail mounting system is the most common roof-mounted structure type that offers a versatile option for mounting solar panels on low and steep-sloped roofs. Usually, the system consists of a set of aluminum module support rails and other necessary components that attach the rails to the roof attachment and to attach the PV modules to the rails. The rail mounting system allows solar panels to be mounted either in portrait or landscape orientation. The rails can be a shared or fixed-tilt design in either orientation.

Rail mountings systems usually include pantiles, plain tiles, slate tiles, trapezoidal sheet metal, corrugated fiber cement, corrugated sheet metal, and standing seam roof.

How Does Rail Mounting System Work?

Each solar photovoltaic panel is attached to the aluminum rails through a set of clamps. Then the rails will be secured to the rooftop using screws and bolts. Usually, this installation method uses flashing to attach the solar panels to the house rooftop. The flashing is the same as the method used for a standard roof vent. Typically, an “L” foot or support component is fixed to the flashing and holds the aluminum or steel rails 2 to 4 inches above the rooftop, upon which the solar photovoltaic panels are mounted.

Pros and Cons of Rail Mounting System

If you are still undecided whether to choose a rail mounting system or not, we have listed some of its pros and cons. 

Pros for Standard Rail Mounting:

• You can use the rail mounting system with almost any kW solar modules in any color of your choice. 
• If you want to blend the rails into your roof shield, rails are easy to blend with them since rails are available in silver and black.
• Many solar manufacturers of rails offer a flash to make it possible to blend the rails with your rooftop.
• Conduits and wires used for installation can be run through the rooftop or across the rooftop.
• Rail mounting system has a long lifespan, and it is the most common type of solar roof installation due to its long histories of success.

Cons for Standard Rail Mounting:

• Older residential and commercial properties may not be applicable to rail mounting since rails are a bit heavy and it can add additional load/weight to the roof making it too much to handle. 
• The solar panel system is more prominently displayed since they sit a little more inches above the roof shingles.
• If you installed them without flashing, the solar panel system is more accessible to bad weather and rodents.

Should you get a Rail Mounting System?

All in all, a rail-mounted solar system offers the most flexibility and capacity when it comes to solar rooftop system design. Not to mention that it has a long history of success in the solar industry, enough proof that it is worth having. In fact, it continues to be the top choice for consumers when they plan to install solar panels at home.

Wholesalers

Solar Products Wholesalers 

Wholesaling refers to buying some products or goods directly from its manufacturer usually at a discount and then reselling it to the retailers for a comparatively higher cost than the original. Basically, wholesalers handle products and package them in small quantities and then sell them to retail customers, either for commercial or personal use. 

Many industries have wholesalers, and that will not skip the solar industries. Nowadays, many solar wholesale stores/firms are operating across the globe, making it much easier for retailers to go solar. Sometimes retailers find it hard to reach direct manufacturers of solar products because some companies do not have their solar stores/shops in public, with that they are not also offering solar products per piece. Through wholesale solar stores/shops, these individuals can easily buy the solar products that they need to replace or maintain their solar systems. 

If you are in need of solar product suppliers for an individual purpose, you may visit some solar outsourcing marketplace to get an updated list of solar wholesalers near your location. There are many solar platforms that provide enough information and data about the solar industry in your region, including all the reliable solar wholesalers in town.

Hong Kong

Brief scrutiny of Hong Kong solar market  

Most people tend to attach Hong Kong to Mainland China. However, the relationship between the two is pretty complex. Essentially, Hong Kong enjoys executive, legislative and judicial independence. Therefore, its solar market is different from the Mainland China market. The independent city hopes to achieve carbon neutrality by 2050. Sadly, renewable energy accounts for 0.2% of the total electric energy consumption.

The most recent publicly available data puts Hong Kong’s solar capacity at approximately 4 megawatts. However, due to recent collaborations with Mainland China, things are looking up for Hong Kong’s solar market. A current forecast predicts that solar energy will account for at least 46% of the total energy consumption in 2050.

 This forecast is based on recent developments in Hong Kong’s solar market. To be precise, the total solar capacity in Hong Kong could reach approximately 4500 Gigawatts in the next three decades. In essence, the city’s solar market offers countless opportunities for solar installers and professionals as we look to the future.
