Solar mounting systems are crucial to maximizing solar energy production, as well as providing solar panels stability. Panels can be mounted on the roof, ground, or on a pole, and may or may not utilize solar trackers. Solar roof mounting systems make use of the space without using land, which is not only significant for larger commercial projects, but also good for residential and small-commercial applications. 

Now You must very curious about what make roof mounting systems so practical? You will know after I show you the advantages of them:

1. Lower cost

Solar First roof mounting systems are installed to a roof or other top area, so they are stationary and do not require a tracking system. With simple structures, they are less expensive and easier to install and maintain than other mounting systems.

2. Long lifespan and reliability

Common mounting systems usually last for about 20 years. While Solar First roof mounting systems with reliable quality could last for about 25 years.

3. Cost-saving in installation and maintenance

The project installation may take a long time and need high attention to details. These circumstances may result in improper installation then increase labor costs. However, Solar First roof mounting systems has completed 30%~40% pre-assembly in the factory , it will greatly save labor cost and time for customers.

4. Less damage

Solar First roof mounting systems attach to roof directly , and use additional rails for connecting the panel racking or frames. Solar First ballast roof mounting systems are concrete or steel bases that use weight to secure solar panels in position. They are often preferable because they do not require drilling holes into the roof, allow removing or relocating systems without damage.

5. Strong resistance to wind and snow

Wind loading issues will greatly reduced because roof mounting systems are not as exposed as other mounting types. What’s more, Solar First roof mounting systems use the existing structure, which can resist strong winds and heavy rain or snow, these harsh elements may be a big problem for ground mounts. 

Considering with so many advantages of the roof mounting systems, what type of roof is most suitable for Solar mounting systems?

Below are a few of the top factors that work together to make your roof compatible with Solar mounting systems:

1．Orientation

Which way does solar panel face? Orientation, or the direction your roof faces, may have a large impact on how productive solar panels will be. In the north of the earth, the best direction for solar panels to face is true south.

While it’s entirely possible to get excellent solar results without a south-facing roof, your system will generate the most energy when it gets as many hours of light exposure per day as possible.

Even many roofs face east or west, most only lose 10%-20% of their energy generation capabilities. If your roof’s orientation is not optimal, speak with a qualified solar installer about your options.

2．Slope of the roof

It influences your solar arrangement. While slope is not as important as orientation, it can affect your system’s energy production capabilities. But what is the best roof slope for solar roof mounting systems? In most places, the ideal power generation angle is 30-40 degrees.

If your roof is too steep, it makes installation difficult and limits the ability of solar panels to perform their highest potential. If you’re installing solar panels on a flat roof, on the other hand, you’ll need to add additional racking to lift the panels to the right angle.

3．The age of roof

While solar panels have become more advanced in recent years, the age of roof is still related to the efficiency of your system. Today, asphalt shingle roofs can last for about 20 years, while materials like slate or metal can last for 40 years or longer.

With this in mind, don’t install a new solar system on a roof that needs to be replaced shortly. Instead, replace the roof first and install the solar panels once the job is done.

4．Hours of shade

While solar panels can work in the shade and on cloudy days, they work better in direct sunlight. Fortunately, Solar First roof mounting systems are adaptable. Even if your roof doesn’t get optimal sunlight, Solar First qualified designer will be able to help you find a creative solution. Often, trimming branches or removing trees around the roof is enough to allow more sun to reach your panels.

5．The material of your roof

While most roofing products are generally suitable for solar energy, composite shingles are clearly the best and easiest for solar installation.

Now, If you’re looking to install on wood shake shingles or clay, slate and tile roofs, you may find it is difficult. These materials are extremely brittle and easily broken, that is why most installers avoid these roof types.

However, Solar First will use professional accessories suitable for this type of roof to assist the solar system installation, the accessories will be hide under the installed panels.

6．The roof shape

The size of your roof has a direct impact on the solar panels you will purchase. According to survey statistics, most residential solar systems are 5 KW, which need about 20pcs 250W solar panels per roof. Generally, each KW of solar system requires at least 100 square feet of roof space. Even if you have a large roof, elements like skylights and broken places even obstacles will limit your available space.

Speaking of here, you may have a systematic understanding of Solar First roof mounting systems. I hope these information can help you when using them.
