Example: If all appliances in a house are simultaneously turned on and consume a total of 6kW, then the peak load is 6kW. Seasonal load calculation accounts for varying power demands throughout different seasons of the year. Solar output can vary depending on the season, so this is crucial for your solar panel system design.
The solar cell is the basic building block of solar photovoltaics. The cell can be considered as a two terminal device which conducts like a diode in the dark and generates a photovoltage when charged by the sun. When the junction is illuminated, a net current flow takes place in an external lead connecting the p-type and n-type regions.
When planning a residential solar project, a crucial part of the process is understanding and correctly calculating your energy needs. These calculations, known as solar load calculations or better known as just “ load calcs ” are fundamental to designing an efficient and effective solar system as well as better permit submittals.
The theory of solar cells explains the process by which light energy in photons is converted into electric current when the photons strike a suitable semiconductor device.
The power required by our daily loads range in several watts or sometimes in kilo-Watts. A single solar cell cannot produce enough power to fulfill such a load demand, it can hardly produce power in a range from 0.1 to 3 watts depending on the cell area.
The power can be extracted from the device in a region shown in the fourth quadrant. The solar cell is the basic building block of solar photovoltaics. When charged by the sun, this basic unit generates a dc photovoltage of 0.5 to 1.0V and, in short circuit, a photocurrent of some tens of mA/cm2.

The equivalent circuit of a solar cell consists of an ideal current generator in parallel with a diode in reverse bias, both of which are connected to a load. These models are invaluable for understanding fundamental device physics, explaining specific phenomena, and aiding in the design of more efficient devices.
A solar cell is a device that converts light into electricity via the ''photovoltaic effect''. They are also commonly called ''photovoltaic cells'' after this phenomenon, and also to differentiate them from solar thermal devices. The photovoltaic effect is a process that occurs in some semiconducting materials, such as silicon. At the most basic level, the semiconductor …

Note that PV cell is just a converter, changing light energy into electricity. It is not a storage device, like a battery. 1.1.1. Solar Cell The solar cell is the basic unit of a PV system. A typical silicon solar cell produces only about 0.5 volt, so multiple cells are connected in series to form larger units called PV modules. Thin

Short circuit current, Isc, flows with zero external resistance (V= 0) and is the maximum current delivered by the solar cell at any illumination level. Similarly, the open circuit voltage, Voc, is the potential that develops across the terminals of the solar cell when the external load resistance is very large (Figure 3).
