The key points of choosing a right material for solar racking

图片
Many users pay great attention to the high power generation of solar power plants, so when purchasing photovoltaic products, they often only take the quality and output power of solar modules into consideration. In fact, the average service life of photovoltaic power plants is at least 25 years, which is determined by the attenuation power of the modules (module power attenuation within 25 years is not more than 20% of peak power). In order to ensure the 25-year service life of the solar power generation system, besides the solar modules, the quality of other components cannot be ignored. Today, let’s talk about the importance of choosing a right material for solar racking. At present, the common types of solar racking on the market are:  stainless steel solar racking , galvanized steel solar racking, aluminum alloy solar racking . ​ Stainless steel solar racking Stainless steel is actually a kind of steel with a lot of impurities and easily reacts with other substances. Moreover, ...

The Importance of choosing a right solar racking system for your roof

As the solar industry continues to climb and dominate the renewables sector, so when purchasing and installing a  solar mounting system , it’s inevitable to understand that a mounting system is a very important part of the install. A solar mounting system is extremely important as it’s how a PV system is able to connect to your rooftop. Solar mounting systems have to hold the system to the roof for a long period. The systems design needs to be able to withstand wind loads and snow loads as well as extreme heat or cold. The main issues for racking systems are whether attaching the panels to the roof will cause leaks through the roof penetration. Secondly, another reason is if the racking system is strong enough to withstand the weight of the solar panels. Also, high winds and snow are another factor to consider, as the extra weight added to the panels can cause stress to the mounting systems. Lastly, it’s important for solar installers to spend a large portion of installation time t...

Calculating minimum ballast for roof mounted solar system

For the  rooftop ballast mount solar structure ,  Here we share two most important points to get the minimum ballast weight. 1. Wind speed, snow load and solar angle Above data are usually request to do the strength calcuation first. For example, 150KM/H with 15 solar angle is around 123KG/M2, then the minimum ballast weight you need is around 85kg/m2. 2. Roof's load-carrying capability What's the age of your building? Do your building have strong steel truss structures? For this part, Pls consult with your local engineers to get your roof's load-carrying capability. For example, If your roof could only bear 30kg/m2, then the calculated ballast weight seems unrealizable.  Therefore, Some more additional method will be applied, Like adding the wind deflector, connecting all the mounting array.  These could help make all the weight, "solar panel+mounting + ballast weight", under the roof capability.

Solar panel mounting for Bitumen shindel

There are two popular Solar panel mountings for Asphalt shingle roof.  1. Solar roof hooks Hooks with flat bottom part could be putted under the soft covering material easily.  Various hooks could connected to different rails, both Horizontal and vertical direction. Adjustable height could be realized with adjustable hook, Like SIC-TH-16. 2. Aluminum L feet with flashing Aluminum flashing could easily slide under shingles, Prevent the roof penetration of snow and rain. 360 degree rotated L feet could be adjusted to match the rail perfectly. Only one bolt design could make the whole production quickly and easily.

How to realize adjustable solar angle for ground solar system?

The solar angle changes a lot from winter to summer. Below Ground mounting structure with Adjustable angle could help solar panels to win more solar energy during solar altitude changes.  1.  Adjustable triangle frame It is made of 100% aluminum, which is usually used with concrete foundation. 2.  Adjustable ballast frame With ballast design, the whole system could be moved easily. 3. Y type adjustable ground mounting The main material is hot dipped galvanized steel, which could be used for large scale ground solar projects. 4. Pole adjustable ground mounting. The solar panel angle is 0-60 degree adjustable, which is suitable for small off-grid projects in the suburbs.

2 Common Short Rail for Metal Roof

According to a report, the COVID-19 has influenced various fields of the energy industry, while the investment in renewable industry has fallen at least among other industry. In the past two years, solar stocks continue to rise. Below rails can save more material cost and installation time. 1. Aluminum short rail system --SIC-TC-15 It is higher than SIC-R-2078-S, which makes the distance between solar panel bottom and roof further that promote heat dissipation of solar panel. 2. Solar panel mini rail -- SIC-R-2078-S There are many holes on it, even though it is low than SIC-TC-15, it can be installed flexibly when you can’t master the distance accurately. In short, both of them have their own advantage, if you are interested in them, pls contact us to get the customized offer.

Required info to design the floating solar structure

To better help our clients prefer the suitable and economic  pv floating structure , below data sheet will be offered to collect the whole project info. It seems a bit difficult for clients, who is not specialized in this field, to fulfilled this sheet, Hence we concluded 5 basic elements to design the floating mounting system. 1. Panel size? Length*width*thickness? panel capacity? 2. Water area map and Water surface size? 3. Any wind speed and snow load request? 4. Latitude and longitude of the installation site? Or tell us your installation city. 5. Solar Panel qty? If you want to build solar project on lake or any water surface,  SIC Floating solar mounting will be your best choose.
