Solar Panel Installation Process For Sloped And Flat Roofs

Solar Panel Installation
A solar panel Installation in your home or office is going to help you reduce your dependency on energy sources that are declining. In addition, it would add a lot of benefits into your daily life that you may not yet know about. 

The solar panel Installation can be carried out on different types of roofs, and the panels can be either flush mounted or tilted up. If it is possible, it would be best if you install the panel mounts when the home is getting re-roofed. When you “flash-in” the solar mounts at the time of roofing, it would eliminate any chances of a leak in the roof. Additionally, it makes it easy to find the rafters when there is no roof. The mounts have to be secured on the roof using stainless steel lag bolts and these bolts are bolted into the rafters. 

The “flashing-in” of the structural attachment points is the ideal method for solar panel Installation. it would also help in eliminating the cost of removing and reinstalling for several decades. The easiest roofs to install solar panels are the composition shingles. Whereas, it is more difficult to work with tile roofs, especially when it comes to carrying the solar panels over them. 

Installation Process 

The process of installation given below describes how you can mount the photovoltaic panels on a sloped roof, followed by another demonstration of installation on a flat roof. It would also guide you about the incorporation of solar mounts on a new roof.

Sloped Roof solar panel Installation

Begin by choosing only professional solar products. The first step in solar panel Installation is to align the mounts on top of the rafters and then they are pre-drilled with pilot bits for avoiding any split in the rafters. You can find the rafters using the stud finder. Next, a laser sight or a chalk line is to be used for keeping all the mounts in a straight line. The mounts are then secured on the roof using stainless steel lag bolts. 

The next step in the sloped-roof solar panel Installation process is to place metal flashings on the mounts. The roofing layer is then hot-mopped around these mounts. The metal rails are then secured with the posts using stainless steel bolts. The solar panels are then installed and connected together to create an array. The sloped-roof installation would end by running the conduit for connecting the panels with the inverter. 

Flat Roof solar panel Installation

The following installation process would demonstrate how the solar panels are to be installed on a flat roof. Begin with professional solar panel products including the mounts. The mounts are first aligned on top of the rafters and rafters and pre-drilled using pilot bits. Use the stud finder for locating the rafters. Usually, they would be 16 inch or 24 inches apart, so that the mounts can be placed at every 48-inch distance. The mounts can be kept in a straight line using a chalk line. 

Next, the mounts can be secured to the roof using stainless steel lag bolts, and the post is threaded into the base. Similarly keep installing all the required mounts and threading the posts.  Take metal roof flashing of 3/4 inches and place them over the mounts. Once the new roof is applied, the metal channel is secured on top of the mounts. The aluminium solar panel racks are then assembled and secured onto this metal channel. Securing the solar panels would then complete the solar panel Installation process.

This completes the two methods of installing solar panels, one on a sloped roof and the other on a flat roof. 

Considerations

• The solar products and the solar panel Installation process can cost you several thousand pounds. But, once you have installed the system, you can remain assured that you would have free power as long as the sun keeps shining. That is if the panels are maintained from time to time. 
• Before you purchase any type of solar power systems, make sure you consult professional and licensed installers. They would be able to guide you about the type of system that would work best in your location. 
• If you require solar power only for heating water for household purposes or swimming pool, you would need a simple solar panel Installation for the solar thermal system. It would usually have a solar collector, connected with the plumbing work of your home. And, these solar collectors are mostly mounted on the rooftops.
