A PV cell is essentially a large-area p–n semiconductor junction that captures the energy from photons to create electrical energy. At the semiconductor level, the p–n junction creates a depletion region with an electric field in one direction. When a photon with sufficient energy hits the material in the depletion region.

Electricity from common sources such as household alternating current (ac) at 120 volts and 60 Hz, or the output of the auto battery at 12 volts direct current (dc) is relatively stable. In comparison, the output (voltage and current) of a PV cell, PV module, or PV array varies with the sunlight on the PV system, the temperature of the PV
The number of batteries required to meet our load demand depends on the level of voltage and current we require at the battery array terminal. Just like a PV module when batteries are connected in series the voltage is higher than a single battery but the current remains the same.

On the battery side, it is the battery which sets the system voltage. The MPPT takes the panel voltage and converts it to a charging voltage which is higher than battery voltage in order to get current to flow into the battery, the voltage is reduced, the current goes up, and the power remains the same. But the battery chemistry will be
Photovoltaic (PV) systems have high fabrication cost and low energy conversion efficiency due to their nonlinear and atmosphere dependent current to voltage (I–V) and power to voltage (P–V) characteristic [1].Therefore, the maximum output power changes with the incident solar radiation and weather conditions especially the temperature.
Yes, you can use your existing battery with new solar panels, but you must ensure the voltage and amperage of the new panels are compatible with your battery and charge controller. Using an incompatible setup can damage your battery and reduce the efficiency of your solar power system.
The voltage at the operating condition = Voltage at STC (V M) – loss of voltage due to a rise in temperature above STC. Therefore, Voltage at the operating condition = 0.79 V – 0.07 V = 0.72 V. Step 4: Determine the required PV module voltage to charge the battery. To charge a battery of 12 V we need module voltage to be around 15 V.

In a normal condition, i.e. when the solar irradiance on the entire PV array is uniform, the power-voltage (P-V) and current-voltage (I-V) curves exhibits a single global MPP . To simulate the fast changing solar irradiance, two different levels of irradiance were selected, 1) highest (Point A, G=1000W/m2 ) and lowest (Point B, G= 300W/m2 ). It
