The easiest way to Mount your Solar Energy Panels

By Christopher Eyres

Solar energy panels are huge flat objects that can catch the wind and they are expensive - so they have to be well fixed. You certainly want to have the very best for your home.

The correct placement In most situations, if you are in the northern hemisphere they should face due south and if in the southern hemisphere, they should point to the north. You could need to vary this slightly if you can never avoid a hill or high trees etc blocking the sun at one end of the day. If the hill to the west ends in you losing the evening sun early, then use your judgment to point your panels slightly toward the east. I stress barely as it has got to be remembered that the early morning sun will be of little worth as it is so low in the sky.

The Angle to the Horizontal The general information here is that the angle of your panels relative to horizontal should be the same as you latitude in spring and autumn, 15 degrees less in summer, and 15 degrees more in winter. If at all practical it's going to be worth mounting your panels so you can change their angle at least four times a year. If you've got to mount them so that they are fixed then go for the same angle as your latitude. You can however want to vary this dependent on which part of the year is your need the greatest.

Materials Utilized in the Solar Energy Panels Galvanized angle steel is mostly appropriate. There is a slight probability of corrosion occurring between aluminium ( the standard material utilized for the frame of the panel itself ) and the zinc used in the galvanizing. However in most out of doors situations that are fairly dry, this shouldn't be a difficulty.

Trackers for More Efficiency Panels will be much more efficient at manufacturing electricity if they're always facing the sun. Trackers are available that serve as the panel mounting and will point them toward the sun.

There are several types to make a choice from : Passive trackers use a system whereby a liquid moves as it is heated by the sun and is used to move the panel, immediately returning to the correct position for the morning. This type is probably going to be the least expensive, doesn't have much to go screwy, and is reported to give satisfactory results.

Active trackers will usually use electrical servo motors to angle the panels and these could be controlled by a light sensor sensing the position of the sun or may be controlled by a time moving the panels to destined positions.

The increased production of electricity that you will get as the results of using a tracker will be larger during the summer than the winter due bigger arc taken by the sun across the sky in summer. This benefit might be often when you least need it and you may feel the cash would be better spent on a couple of additional panels.
