Is residential solar panels a viable option?
Practice has instructed many home owners that the correct mounting of the residential solar panels has a definite affect on the efficiency of the system as such. To put it literally, many people in truth started to track the sun; this means that the residential solar panels revolve about an axis so as to track the sun from dawn to dusk.
The inclination angle of the solar system depends on the season and on the latitude, thus it could be nearer to straight in summertime, and very steep or virtually upright in winter. Experts apprise home owners to install the residential solar panels by calculating the angle with a very simple formula: in summertime it’s the latitude minus fifteen, and in wintertime it is the latitude plus fifteen.
The advantages of residential solar panels that bank on trackers are manifold. First of all, you’ll notice a better power output, granted the fact that the panels can face the sun just about all day long. Then, the system as such is more appropriate for people living nearer to the equator, but this doesn’t mean the rule is not valid for the rest of the world areas. You see the deviation in efficiency with tracking residential solar panels if you also use the system to produce heat and not just electricity.
There are however some disadvantages to the combination of residential solar panels and mechanic trackers. The major thing here is that unlike the panels that are meant for long term resistance, the trackers could be subject to never-ending maintenance. Then, on very breezy weather, you may have the surprise of having the residential solar panels orientated in the wrong direction.
Furthermore, the peak(a) efficiency of the residential solar panels is in summertime time when it is very improbable that you’ll need excess electricity. And last but not least, the price of a tracker equals that of two solar energy panels.
It is up for every home owner to analyse the pros and cons of combining the use of residential solar panels with tracking devices. The conclusion should be made taking into consideration all the objective factors in question, since we are talking about a rather significant investment that is not at all to be neglected.
All in all, the residential solar panels can provide more than acceptable results even in the absence of such devices; south orientation is consequently one of the most popular, but the east and west directions are also favored. Depending on the position and architecture of the house, it is good to keep in mind the fact that solar energy panels stay a valuable energy source virtually anyplace on the globe.
