When researching the topic “How Does a solar panel work,” one will find mixed information on how the energy is produced through the panels and the cells themselves. A number of solar cells are to work in series with a power supply system suitable to achieve with an electrical device or storage.
by the panel, the electricity is a direct current (DC) which is commonly referred to as the negative and positive terminals. Like the battery which also has a positive and negative terminals, the cells operate in the same meaning.
In a series circuit, two cells 4 terminals (two positives and two negatives) have, a bigger cell when you simply connect one of the negatives to one of the positive terminals (positive to negative and vice versa) . What remains only one negative and one is positive but the tension of both panels were added (0.5V + 0.5V = 1V). Two cells, a larger cell. Likewise, if you have 12 cells, you can put them in series simply by connecting all the positives with the negatives and you finally will not matter what you do with just one negative and one positive at both ends.
In parallel, the same two cells that four terminals (two positives and two negatives) have to be connected differently. One positive pole is connected to one positive terminal and one negative one negative (positive to positive and negative to negative). These two cells do not become a large solar cell instead, they started to work together to amplify the current that is measured in ampere (A). Here we can probably say that the two threads was a great thread, in this case two positives was a greater positive wire and the same goes with the negative wires. Parallel connections are only used when you have reached your target voltage across a series-connected solar cells. A series of 36 cells can generate around 18V (36 x 0.5 = 18V) and 18V this is the ideal voltage for a 12V battery charging. To quickly charge the battery, you would add more solar cells, but must keep the same voltage (18V), and to achieve that, you need to connect to the next group of solar cells in parallel connection (positive to positive and negative to negative).
When connected groups of three “series” connected solar cells, a connection of three strings of solar cells and all three strings, a module or called hot solar panel. It is a solar panel as all the other components, such as the frame rear sheet, the coverslip and the junction box are integrated.
A solar panel, in turn, can be connected to a solar panel is also in series or in parallel depending on the design of the photovoltaic installation. Multiple solar panels connected in a series, say 12 panels, is also considered as a string in parallel with another string or more strings. Multiple strands of solar panels or an array or solar panel.
It is important to note that, in a series circuit, the voltage (V) during adds a parallel circuit, increases the ampere (A). Voltage multiplied by Ampere results when determining Watts (VXA = W)
At this point, you should be able to understand the relationship of small solar cells to its larger counterpart, the solar panel. If you can build a solar panel, then basically you can build a large solar panel similar to a solar power plant.
It is up to you which one to buy solar cells, but make sure the correct order amount of cells based on the solar panel you intend to do that is something that this article relates to the future how-to sections . Also be aware of the electrical ratings of the solar cell, which is of importance in the achievement of the quantity of electricity that you need to reach. Typically a solar cell and a DC voltage of 0.5 V nominal power approximately 4WP. Hopefully this information helps you search for “how does a solar panel work.”
