Characteristics of solar energy
Comparable electric circuit
a solar power component can be seen as a black field that with two connections, producing a present, I, at a current, U.
For the purpose of the electrical traits of a solar power mobile, the within of that black colored box are explained by an electric cicuit with only 4components:
The connection between we and U of just one cell is then expressed by:
with heat, T (in Kelvin), Boltzmann constant k = 1.38e-23 together with elementary cost e = 1.602e-19. Using this formula, we are able to determine maximum power things, additionally behaviour under different temperatures.
In a component, some cells are positioned in series into a string, and numerous strings in parallel. Putting cells in show increases the voltage, whereas putting cells in parallel adds to the current, so:
Current-Voltage Curve: I-U Qualities
The I-U equation can only be solved iteratively. The graph to the right reveals a normal bend.
Sensitiveness: The curve is highly sensitive to alterations in:
|In practice, nothing for the parameters within the I-U characterisitc curve is directrly observed. Instead, manufactureres offer the after information:
Existing that flows whenever U = 0
