The roof is the best place to install a solar panel because it receives the most sunlight. But installing them can be a complex process, so it’s best to leave this project to the professionals.

The Basics

Solar panels are a growing way for homeowners to reduce their utility costs and go green. But they also can damage roofs if they’re not properly installed.

The first step is to make sure your roof will receive enough direct sunlight. Your solar panel should get a continuous amount of sun for 6 hours or more to recharge its batteries.

To do this, use a solar calculator to determine where your home’s roof should face and what orientation is best for getting the most energy from the sun.

The next step is to set up stanchions with rails and mount the solar panels to them. This can be tricky, but if you use a framing square to ensure the panels are square with the rails, it’ll make life much easier later on, Click over here now.


Before installing solar panels on your roof, make sure you have all the materials and tools needed. This includes solar panels, PV wire, stanchions, rails, mounting brackets, a drill, screws, and lags.

You’ll also need safety equipment like fall protection and a ladder lift to move panels and other heavy items from the ground to your roof. It’s best to have everything in reach so you don’t have to make frequent trips from your roof to the ground to get something.

Next, you’ll need to check the roof to ensure it can support the extra weight of the solar panels. Typically, they weigh between 2.5 to 2.7 pounds per square foot, so it’s important to have a structural engineer evaluate the roof before putting up your panels.


Before installing solar panels, be sure to have your roof inspected by a professional. This will ensure that your roof is in good condition and that it is not going to need any repairs soon.

Once the inspection is complete, the contractor will design your solar panel system. This will take one to four weeks.

After that, the installers will begin installing the panels on your roof. The process can be done in one to three days, depending on the size of your system.

Using a ladder, scissor lift or boom lift, the installers will mount the panels to the roof. During the process, make sure to wear protective equipment such as gloves and eye protection.

After the installation is completed, it is time to submit the solar panel designs to your local government for permitting. The permit process can vary from region to region, but the contractor will be familiar with your area’s rules.


Solar panels are a great renewable energy source, but they require some maintenance. These simple steps can help your system produce the most energy possible for years to come.

Panels should be cleaned at least once a year, although more frequent cleaning may be required in certain locations. Rain usually keeps panels clean, but if the weather hasn’t been wet enough recently to wash off dirt and debris, you can have your solar panels professionally cleaned.


Other maintenance tasks include checking for loose screws and bolts, which can lead to decreased performance over time. Similarly, inspecting for wires and connections that may be damaged or gnawed by birds and other critters can also be beneficial.
