1.Some factors need to be considered to know if your rooftop is ideal to generate electricity from solar panels.

（1）Availability of sunlight

Sunlight is the main factor of solar energy harvestation. Whether your rooftop can harness energy is determined by the amount of direct sunlight it gets during the day. With surroundings and weather taken into account, your rooftop should at least get 4-5 hours of direct sunlight in most of its area. The more the duration and area of well-lit space, the more electricity you generate!

（2） Direction of Sun

Solar farms ideally harvest energy by changing the direction of the solar panels to match the direction of the sun, taking in as much light energy as possible. This is not possible in most rooftop systems as it is not everyone’s cup of tea to keep moving the solar panels. As such, the orientation of the panel once fixed, plays a key role in the harvesting of energy.

（3）Choosing the suitable system

The contents of this article should help you decide the suitable system for you to use on your rooftop. It is always good to ask for help from the internet or any other available sources of information before deciding on your solar rooftop system.

2.Step-by-Step Process for Installing Solar Panels

Step 1:

The first step when installing a solar panel roof mount is to figure out where the stanchions go. Stanchions are giant screws that hold the solar panels in place. The mounting is made to be durable and to withstand what is known as “upforce”, a pull that could rip the panels from the roof. To determine the proper placement of the stanchions, find the rafters in your roof using either your home’s blueprint or a stud finder. The stanchions should be placed at least four feet apart.

Step 2:

The next step is to attach the screws to the roof. Carefully create holes in the rafters using a drill.

Step 3:

Thirdly, put the screws in the holes and secure. Make sure that the upper and lower aluminum rails are secured to the stanchions using bolts. Use an impact driver for maximum tightness. Then, the screws should be sealed. This maintains your home’s thermal envelope. Thermoseal roofing is the best way to do this. It will keep a tight lock on your roof, not letting any of the elements inside. Thermoseal roofing is the way to go. Properly-installed stanchions will not leak.

Step 4:

The fourth step for installing solar panels is to measure the distance from the rails. Place a measuring tape diagonally from the top of one rail to the bottom of the rail directly across from it. Do the same on the other side. These measurements should be exactly equal. If they are, you know that the rails are parallel. If the measurements are not equal, then adjust accordingly.

Step 5:

After you make sure the rails are square, it’s time to install the middle rail. The middle rail should be aligned with the upper and lower rails.

Step 6:

The sixth step brings power to your solar panels. It involves putting wires into your panels and running them to your power inverter kits, creating your conductor systems. Then, you will install a power inverter kits underneath every one of your panels. Then install some 6-gauge copper grounding wire onto your inverters. This finishes the conductor systems. These wire connections should be connected from one solar array to the next one. 

The Last Step:

Finally, you will place the panels on top of the previously-installed stanchions. The plug connections need to be joined and the retaining clips must be screwed onto the rails to ensure that the panels are secure.

Once you have finished the previous step, it is time to move on to more electrical work. Extend some wires from your panels and connect them to an electrical meter. The wires also need to connect to an electrical sub-panel.
