The easy way to Mount your Solar Panels

Solar panels are huge flat objects that will catch the wind and they are pricey - so they have to be well fixed. You surely want to have the very best for your house.

The proper placement In most cases, if you are in the northwards hemisphere they should face to the south and if in the southern hemisphere, they should point northwards. You might need to vary this barely if you cannot avoid a hill or high trees etc blocking the sun at one end of the day. If the hill to the west results in you losing the evening sun early, then use your judgment to point your panels slightly toward the east. I emphasize a little as it's got to be recalled that the early morning sun will be of tiny worth as it is so low in the sky.

The Angle to the Horizontal The general advice here is that the angle of your panels relative to horizontal should be the same as you latitude in spring and autumn, fifteen degrees less in summer, and 15 degrees more in winter. If at all practicable it will be worth mounting your panels so you can change their angle at least four times per year. If you've got to mount them in order that they are fixed then go for a similar angle as your latitude. You will however would like to alter this depending on which part of the year is your need the best.

Materials Utilized in the Solar Cells Galvanized angle steel is usually acceptable. There is a slight possibility of corrosion happening between aluminum ( the ordinary material utilised for the frame of the panel itself ) and the zinc used in the galvanizing. However in most outdoor situations that are reasonably dry, this should not be a problem.

Trackers for More Efficiency Panels will be much better at making electricity if they are always facing the sun. Trackers are available that serve as the panel mounting and will point them towards the sun.

There are several types to make a choice from : Passive trackers utilise a system whereby a liquid moves as it is heated by the sun and is used to move the panel, immediately returning to the proper position for the morning. This sort is likely to be the cheapest, doesn't have much to go screwy, and is reported to give satisfactory results.

Active trackers will generally use electric servo motors to angle the panels and these might be controlled by a light sensor sensing the position of the sun or might be controlled by a time moving the panels to predetermined positions.

The increased production of electricity that you are going to get as the results of employing a tracker will be greater during the summer than the winter due larger arc taken by the sun across the sky in summer. This benefit may be typically when you least need it and you may feel the money would be better spent on 2 extra panels.
