The larger the plant, the higher the likelihood of a PPC requirement. Utility scale plants have Power Purchase Agreements (PPAs) and Interconnect Agreements (IAs) that explicitly require the ability to curtail or to control to a certain power factor. These functions require a PPC. Lower megawatt sites that aren’t subject.

PWM controllers: PWM controllers regulate the voltage from the solar panels to the battery at a fixed rate. They're well-suited for smaller, simpler solar systems and come with a number of useful features, including low cost and low maintenance.
Batteries come in many types, including lead-acid, flow, lithium-ion, and nickel-cadmium. The charge controller manages the power flow from the solar panel to the connected battery. Without a battery connected to the system, charge controllers are not required. They work by ensuring the battery charges to the maximum level to enhance its longevity.
This article will focus on these solar power system components and how to select and size them to meet energy needs. A complete solar power system is made of solar panels, power inverters–specifically DC to AC–charger controllers, and backup batteries. Solar panels are the most common component. They are also referred to as photovoltaic panels.
This capacity typically dictates the rating of your solar charge controller and ranges from 10A up to 100A. Knowing how to configure the solar charger controller settings according to your specific solar battery type for an effective solar energy system can significantly enhance the charging efficiency.
