There are two major ways in which solar panels can be installed. Before proceeding to look at those two ways, we may mention that solar panels are the main components of the systems through which electric energy is tapped from the sun. It is only when these panels are hit by light energy from the sun that an electron flow from them is triggered, with the force (or rather, current) emanating from that electron flow being the ‘electric energy’ tapped to do various tasks. These panels are typically installed on roofs, where they can get maximum exposure to the sun, seeing that it is the light energy from the sun which triggers the electron flow, whose force is eventually harnessed to power various appliances. It turns out, as mentioned earlier, that there are two specific ways in which the solar panels can be installed on the roof:
1. Where the solar panels are simply placed on the roof: this is a particularly good approach if you are considering tapping into solar energy (through the panels) long after you are through with your home’s construction. It wouldn’t make sense to pluck parts out of the roof, in order to get a place where you can place the panels, while you could as well simply put the panels on top of the roof. Of course, the installation of the panels on top of the roof has to be done carefully: it is not just a question of dumping the panels there. Care has to be taken to ensure that they are secured. And the installation has to be done in such a way that the whole roof doesn’t end up being messed up in the installation process. In this installation, it is always essential to keep in mind that the placement of solar panels wasn’t factored in the original design, and calculations done to see whether it would be safe to install the panels. But most roofs are strong enough to bear the weight of these panels (since, after all, the panels are usually relatively light). More important is the question of slant: seeing that a very steep roof may not be secure enough to uphold the panels. Furthermore, a very steep roof may not give your panels proper exposure to the sun.
But in the final analysis, wherever viable, there is no denying that the installation of solar panels on top of the roof is the easiest (and thus typically cheapest) installation.
2. Where the solar panels are inbuilt into the roof: this is a particularly good approach if you have the desire to tap into solar energy at the time when you design your house. It is also a good approach if you have a keen sense of aesthetics, where in a bid to protect your roof’s aesthetic appeal, you may decide to make use of solar tiles, which camouflage with the rest of the roof. The good thing with this approach is in the fact that the solar panels are very well secured (since they end up being incorporated into the roof, rather than simply being placed on top of the roof).
