 TYPES OF SOLAR PANELS AVAILABLE

MONOCRYSTALLINE PANELS

The solar cells in monocrystalline panels are slices cut from pure drawn crystalline silicon bars. The entire cell is aligned in one direction, which means that when the sun is shining brightly on them at the correct angle, they are extremely efficient. So, these panels work best in bright sunshine with the sun shining directly on them. They have a uniform blacker color because they are absorbing most of the light.

Pure cells are octagonal, so there is unused space in the corners when lots of cells are made into a solar module. Mono panels are slightly smaller than poly panels for the same power, but this is only really noticeable on industrial scale installations where you may be able to fit a higher overall power with monocrystalline.

Polycrystalline Panels (also known as multicrystalline)
Polycrystalline panels are made up from the silicon offcuts, moulded to form blocks and create a cell made up of several bits of pure crystal. The individual crystals are not necessarily all perfectly aligned together however, this mis-alignment can help in some circumstances, because the cells work better from light at all angles, in low light, etc.

Since they are cut into rectangular blocks, there is very little wasted space on the panel

With great service, industry’s leading solar products and unrivalled experience, you can trust us to get your solar panel installation right first time.

Which Direction Should Your Solar Panels Face?

In most cases, if you are in the northern hemisphere they should face due south and if in the southern hemisphere, they should point due north.
You may need to vary this slightly if you cannot avoid a hill or high trees etc. blocking the sun at one end of the day. If hill to the west results in you losing the evening sun early, then use your judgement to point your panels SLIGHTLY towards the east.

Our Solar PV Engineers are only a phone call away……just incase you need assistance/ guidance.

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, 15 degrees less in summer, and 15 degrees more in winter.
If at all possible, it will be worth mounting your panels so that you can change their angle at least 4 times per year.
If you have to mount them so that they are fixed then go for the same angle as your latitude. You may however wish to vary this according to which part of the year your need is the greatest.

Materials Used

Galvanized angle steel is usually appropriate. There is a slight possibility of corrosion occurring between aluminum (the normal material used for the frame of the panel itself) and the zinc used in the galvanizing. However in most outdoor situations that are reasonably dry, this shouldn’t be a problem.

Further Expansion

If possible, plan your method of mounting solar panels so that you can easily add an extra panel or two to the system. You may find, when you have experience of using your solar power system that you would benefit from extra capacity.

 Trackers

Panels will be much more efficient at producing 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 choose from:

Passive trackers use a system whereby a liquid moves as it is heated by the sun and is used to move the panel, automatically returning to the correct position for the morning. This type is likely to be the cheapest, doesn’t have much to go wrong, and is reported to give satisfactory results.

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

The increased production of electricity that you will get as the result of using 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 mostly when you least need it and you may feel that the money would be better spent on a couple of extra panels.
