Match the Wattage to Your Needs. Finally, look at the wattage of the solar panels. Higher wattage panels can produce more power and may take up less space on your roof
Customer ServiceThe current-voltage (I-V) curve is generated during the flash test of a solar panel and depicts in a chart the relationship between electrical current intensity (I) and voltage (V). What are the technical parameters
Customer ServiceSolar panels generate electricity when sunlight hits the photovoltaic cells, causing electrons to move and create a current. The amperage produced by a solar panel depends on the amount of sunlight it receives and the efficiency of the cells. For instance, on a sunny day, a solar panel might produce a higher current compared to a cloudy day. Wattage:

The electrical characteristics of a photovoltaic array are summarised in the relationship between the output current and voltage. The amount and intensity of solar insolation (solar irradiance) controls the amount of output current ( ), and the operating temperature of the solar cells affects the output voltage ( ) of the PV array.
The feedback is the voltage produced as the solar panel current flows through the current-sense resistor R4. The more current the panel produces the greater is the feedback voltage produced at the current sense resistor (V = I*R).
But a photovoltaic array is made up of smaller PV panels interconnected together. Then the I-V curve of a PV array is just a scaled up version of the single solar cell I-V characteristic curve as shown.
