Photovoltaic modules for isolated 12V applications
Solar panels are also known as solar panels, solar modules or photovoltaic panels are made up of solar cells capable of producing electricity from the solar radiation that hits them.
Photovoltaic panels, solar panels or solar panels can be classified according to the type of photovoltaic cell in:
- Monocrystalline: Composed in cells of a single silicon crystal. They are recognized by the shape of the cell, circular or octagonal from cut circular cells.
- Polycrystalline: Formed by cells with multiple crystallized silicon particles. The cells are usually rectangular in shape and more bluish in color with more irregular coloring.
Amorphous: Also called 'thin layer' composed of uncrystallized silicon.
What is the Solar Plates made of.
The typical cell has an area of approximately 100 cm2, produces between 1.5W to 3W of power with a voltage of 0.5V and 3A of intensity. To take advantage of the energy generated, cells are connected in series and parallel until adequate values of voltage and intensity are reached. That is why in the 12V panels we will find that they have 36 cells, there are panels with 72 -144 cells and grid connection panels that have 60 cells.
The operation of the solar module will be completely linked to the solar radiation that the group of solar panels is receiving. These solar panels installations are very profitable, since they allow converting the energy cost of a home's pool treatment plant to zero. All the types of solar panels exposed here are also optimal for isolated solar installations.
Depending on the type of isolated installation that is required, we will look for a type of solar panel of 12V or 24V, depending on the size of the installation. Depending on the working voltage of the solar installation, their connection mode will be different.
Data when installing photovoltaic panels.
Before carrying out the photovoltaic project, we recommend that you take some points into account so that the installation meets the expected performance.
- How to place the solar panels
The main aspect to take into account when installing the solar panels is the orientation of the photovoltaic panel, it should be to the South and with an inclination depending on the latitude and the use that the installation will have. On the other hand, this placement can be done on different surfaces, and they will all be just as good as long as we comply with the proper inclination and orientation, since if the orientation is not ideal or we do not have a good inclination, we will have certain losses.
Another point to keep in mind is the presence of shadows on the solar panels, if there are shadows even if they only appear on a panel or in a reduced area, production is greatly reduced. If the installation is made up of panels in series, by affecting one panel we affect the entire series, so it is very important to have complete absence of shadows in the photovoltaic field.
For this reason it is recommended to study in detail the place where the panels will be placed and check that they will not receive shadows from trees, chimneys, buildings, etc. Once the installation is done, if we are faced with a problem like this, the solution is difficult and expensive.
- Structures used in photovoltaic installations
We must ensure that the kit or system that we are going to acquire has the structure that we need for the chosen location. There are many depending on the installation site: flat roofs or roofs, uralite roofs or sloping sandwich panel, in elevated structures, tile roofs, metal roofs or boats. All locations have a suitable structure for its correct fastening. Solar panels have dimensions and weight due to which we must be sure that they are correctly installed, always using an appropriate structure.
The subjection of the structures to a stable and safe surface is another point to take into account, since we remember that the installation of the solar panels occurs outside, being exposed to strong winds, storms and the most demanding atmospheric conditions.
