Learning to attach solar panels to your roof is pretty uncomplicated, though you must be aware of things that will impact the safety of the process and the durability of the product. Installation involves bolting solar racking into the rafters of your home (roof side) which then provides the means for attaching the panels.
Something of which to be mindful when installing solar panels is not the weight or threat of the roof falling in, although this is a concern, but the up force that can be created by the wind. This means it’s vital for the solar racking to be securely attached to the roof, not just by the top layer of sheathing, but bolted into the roof itself. Finding the precise center of the rafters can be time consuming but it will also insure that the installation remains securely in position.
Installation on a flat roof is very different from a pitched one, as it is necessary to build some sort of scaffold system under the solar racking, to keep them at the desired tilt angle. Also, the material used on the roof will impact the cost of the process, with tiles being more expensive. This is due to the weakness of the tiles, the risk of needing to replace them because of cracking and the time it will take to drill through them all. Because of these factors, composite, or asphalt roofs make for the easiest installations.
The position of your solar panels can have a huge impact on how much electricity is produced and thus available for use. Be aware of the fact that placing your panels near trees could result in a shadow being cast on them and therefore their not being very productive. Also, note that the shadow made by your house moves at least 22 feet farther to the south in the winter. If your panels end up falling under that shadow you won’t harvest as much electricity during those cold winter evenings.
Solar panels will produce the most electricity when the solar racking places them as close to perpendicular as possible. Because the sun changes angle throughout the year, you will have to adjust the angle they face at least 4 times each year. Again, the closer to perpendicular they panels sit, the more electricity you will have at your disposal.
