So, to regulate the voltage from the solar panel, a voltage regulator is used in between solar panel output and the battery input. The solar panel voltage regulator acts as a blocking diode when the battery voltage is greater than the solar array voltage.
The voltage regulator ensures that the voltage from the solar panel never exceeds the safe value required by the battery for charging. Generally, there is no need for a charge controller with small maintenance. If the panel puts out less than or equal to 2 watts for each 50 battery amp-hours, then there is no need for a regulator.
Solar panel voltage controllers are essential in off-grid solar systems. These regulators contain a direct connection between the solar panels and battery storage. The voltage controllers use a transistor instead of a relay to open the array. The PWM regulator self-adjusts by varying the widths and speed of the pulses sent to the battery.
The parallel combination is achieved by connecting the positive terminal of one module to the positive terminal of the next module and negative terminal to the negative terminal of the next module as shown in the following figure. The following figure shows solar panels connected in parallel configuration.
PWM voltage regulators cost less and are used in small solar panel systems. These voltage controllers allow the array voltage to vary from the battery voltage which makes it easy for the regulator to find a point on which the solar array produces the maximum power. In the case of larger solar arrays, heat dissipation can become a problem.
This circuit makes sure that the voltage from the solar panel never exceeds the safe value required by the battery for charging. Normally to get optimum results from the solar panel, the minimum voltage output from the panel should be higher than the required battery charging voltage.

This is done by multiplying the short-circuit current of your whole solar array by 1.25 (NEC''s safety factor). For example: Consider 2 parallel wired solar panels, and each of these panels had a short-circuit current of 5.8A. The amperage rating of the PWM charge controller can be calculated as follows: PWM Amperage rating = 2 x 5.8A x 1.25
