Many governments around the world have made an effort to concentrate on exploring the feasibility and development of alternative and renewable energy. Solar power is one of the most popular choices, and its use has even experienced significant penetration into the private sector as well. For quite a number of years, many homeowners have installed solar panels in order to power their houses, and the roof is the optimal place in which to place these devices. Here is a tutorial on how to install solar panels on a roof.
Before the actual installation takes place and any holes are drilled, be sure to inspect the surroundings of the roof for potential blockages of the sunlight. Tall trees nearby may cast significant shadows that will keep the sun’s rays from reaching the roof. Also be sure to find the portion of the roof that is hit with the majority of the sunlight during the day. Here is the section of roof on which you will want to place the solar panels, the brightest part of the home and the one away from branches and limbs that obscure the sun.
The optimum time at which to install the solar panels is while the roof is torn off and a new one is being put on. This is because the rafters will be completely exposed and easily located. The reason why this is important is because the mounts that hold the rails for the panels are to be attached to the rafters. Lag bolts are to be used to fasten them due to their strength and durability. Before the new roofing materials are put in place, the mounts are able to be flashed in to the roof, creating a seal that water will not leak through. This protection against moisture will prevent the need to tear up the mounts and roof to replace them because of water damage for many years.
You will want to align the mounts to the rafters and drill pilot holes into the beams. Using a laser guide or simply a chalk line, be sure that the mounts are straight. Using stainless steel lag bolts, fasten the mounts in place. The metal rails that will support and hold the solar panels in place are then attached to the mounts. These are secured with 3/8″ stainless steel bolts. The solar panels are then connected to the rails and a conduit is run to connect the solar panels to the inverter.
This manner of installation will provide a low profile method for gathering the sun’s energy and converting it into electricity to heat and power a home. Some homeowners prefer that the panels rest in the roof completely flush, but this takes more time and work. The more conventional installation described will provide free energy production without water leaks and eyesores. It is also rather simple and cost effective.
