Once you have your solar panels, you must decide whether to mount them in your backyard or on the roof. If you have enough space in the backyard, and you hinder not mind your garden view, this would be the easiest choice. On the other hand, most people seem to choose for the roof, because the panels are not in the way. Whichever way you go, a detailed plan is a must, because those mistakes will occur, and it will also be by your building department needed when you apply for a license.
Ground mounting for solar panels .
This is one of the best ways to mount your panels as you can mount each array on a pole and the vertical angle of the panels can be changed in order to maximize exposure to the sun as the seasons change .In the spring and fall you have the panels at an angle equal to your latitude. In the summer the corner latitude minus 15 degrees and in the winter the latitude plus 15 degrees. There is a wide range of opportunities to stretch from pole mounts that sit on the floor available solar supply houses. You can even buy a tracking unit which will follow the sun throughout the day, but they are pricey and will likely pay off enough extra power does not produce. You can also build your own mounts locally obtained building materials. One consideration is the most local codes have your panels in a fenced yard, or from the ground at least 8 feet (2 1/2 meters), so beyond the reach of the public.
Roof installation for solar panels.
The first consideration is the angle of your roof. If it is not to be flat, the panels can be mounted on the plane of the roof, and this is the simplest and most pleasant from an aesthetic point of view. If the angle of your roof corresponding to your latitude is in perfect shape. Plus or minus 10-15 degrees will also work, but with a greater variation of a flat roof, you have to stretch that will hook you build panels.The next consideration is the type of the roof, because you do not want to go to any lengths to install a solar system, and then have a leaking roof. A composition or metal roof are quite easy to install, because keeping a little roofing compound from the water, but if you have a concrete or tiled roof, you better have a good roofer help with installation.
It is important safe bolt deadlocked on the roof rafter or other framing. You do not want to lose your series in a storm. Make sure the deadlock properly flashed and sealed, so there is no possibility of a leak. Space the projections about 4 feet (3.1 meter 1) from each other to the bottom rail of aluminum fit channel long enough to fit the series. A second rail is then installed to hold the top of the solar panel. Now, the panels are ready to be installed by means of brackets which slide into the channel. But first we need to install the electrical wiring and the lead and make sure the rails are properly grounded.
install the wiring and conduit.
As part of the plan submitted to the building department is a circuit diagram that the wire size, conduit and junction boxes used are specifying. Remember that the line depends on the voltage and distance from the transducer as dictated by a wire size table. I suggest you a measure of the wire larger than indicated because heat buildup and the associated voltage drop will reduce use. Make sure all connections and boxes are waterproof, because repairs at a later date usually complicated. You are now ready to install the panels and hook them to the wiring. Remember that the panels produce electricity when the sun hits them so make sure you have not connected to the inverter and use caution when handling any exposed wires.
