Solar panels are one of the most convenient ways to produce energy from a renewable source as vast as the sun. These panels are usually easy to use even for those who are not technologically advanced. They work quietly but efficiently to convert the sun’s powerful rays of thermal and light energy to electrical energy.

Installing solar panels can be easy if done properly. It is best to install them or the photovoltaic cells as the house is being built. This way, they can be directly attached to the roof and match the roof. This would also lessen the cost of the installation. In addition, the panels can be fitted well into the roofs to minimize leaking of the roof and the panels. Installing the panels should be done correctly for them to work well. Therefore, these should be secured well to the rafters using stainless steel lag bolts. Locating the rafter is quite easy when there is no roof.

Installing solar panels is also best when the roof is not yet in place because the correct type of roof material can be used. Because these panels are considerably heavy, the roof material should be durable enough to withstand the pressure and the weights of the panels. Roofs made of galvanized iron sheets may crack easily. Composition shingle roofs are sturdy enough to hold them. Cemented roofs are also good.

In general, solar panels are installed on the roof to make the most of the sun’s energy. Since most roofs are sloped, care should be taken that the expensive solar panels will not slide down the slope. To best achieve this, the mounts should be placed securely before bringing the panels to the rooftop.

The first thing to be done in installing solar panels is to check the materials that came from the manufacturer and identify their correct use. Some panels have bottom and top mountings to secure them, and identifying these two would speed up the process.

The area to be used for the solar panels should be measured carefully according to the manufacturer’s instructions and also based on the mounting guides on the panels. To avoid splitting the rafters, the holes should be drilled with a pilot bit. The holes should align well and in a straight line. Using the stainless steel lag bolts, the mounts should be secured to the rafters. Careful checking would ensure that the bolts are tight.

Over the mounts, the metal flashings that come with the cells should be carefully sealed. The bolts should be checked again for overlooked and unlocked ones. The solar panels are then installed over the metal flashings. The wires under and around the panels should be carefully checked so that they can be easily located for attachment to the system. After they are installed, a protective layer of material is placed on top to maximize efficiency and minimize the effects of environmental factors.

After installing the solar panels, all the connections should be re-checked for security, and the cells are tested to see if they run correctly.

So when you are planning on getting solar panels installed, hope this article will give you an overview picture on installing solar panels.
