Solar panels work best when they are placed in a certain way. It should be taken into account the position of the sun and the angle at which the solar panels are installed. Also, the panels have to be a given period cleaned for optimal use of the system. Under what angle should I place my solar panels?
What are solar panels?
A solar panel is, in fact, a collection of a vast number of solar cells. A solar cell is called an ambiguous word also called photovoltaic cell (abbreviated to PV system, from the English photovoltaic cell). The majority of solar cells are made of a layer of the material silicon. For this to make a silicon semiconductor, there is added to the top of a phosphor layer and a layer at the bottom. The whole is placed for the protection between two transparent plates. These were first made of glass, but nowadays also made from various transparent plastics.
The wind direction in which the solar panels can be determined by the rotation of the vertical axis. Here the course should be taken into account when the sun moves in the sky. The ideal angle of inclination is dependent on the wind direction of the solar panels.
When the wind direction is not clear, the panels must be placed with an inclination angle of 36 degrees. However, the optimum angle is somewhere between 15 and 55 degrees. It ensures that there is much sunlight as possible can be collected. If you have a flat roof, it is possible to use racks that hold the solar panels correctly in place. Persons living abroad are advised to find out what is the optimal angle in the country. This difference depends on how far you live from the equator. Because when you live near the equator, the solar panels can be thinner for better returns.
A tool to determine the most advantageous angle
It can be made of a so-called ‘disc irradiation’ to know exactly what slope angle yields the most. A radiation drive is also known as a ‘radiation diagram. These are schematic representations of the potential yield per situation. Here, the yield is in fact shown in combination with the different directions and angles of inclination.
Dynamic solar panels
The sun can be seen throughout the day at various locations above the horizon for fixed solar panels but a short time is optimally used. It is just the moment when the sun shines on the most, and thus, the yield is highest. To ensure that the solar panels as possible are directed towards the sun, one has invented solar panels that rotate with the sun. To make the panels move is made of engines use.
An engine replacement
The engines that are sometimes used but costs energy which lost some of the gains. However, researchers in 2011 developed a method whereby engines have become obsolete. There is at this moment absorbs among other things the use of a black copper plate which heats and can hold. This makes it unnecessary to run along the track with the sun.
The seasons are very decisive for the return. The days are shorter or longer and vary the position of the sun. It is very decisive for the amount of sunlight that passes through the atmosphere on a particular day in the year. It ‘s hard to take this into account. Also, there is a chance that there is snow or leaves come into contact with the panels. This may even cause the panels temporarily useful. It is advised to take this into account.
Solar panels work best when they are clean. Namely, they can become contaminated by, for example, leaves or droppings of birds. It allows the panels to be cleaned. Showers are not always high enough to prevent pollution. If this is not done, it may even be reduced by 10 percent the energy yield annually (in a slow manner).
Wear after prolonged use
The ability of the panels decreases every year for a small percentage. Most manufacturers guarantee that the solar panels still at least 90% after ten years of application on the time of purchase. After the age of 25 this would be 80%. This warranty is part of the ‘performance guarantee’. It describes each year what should be the minimum return.
