1. Solar Photovoltaic modules generate electricity when exposed to sunlight. (Solar modules are solar cells connected by strings in series / parallel arrangement and then vacuum laminated).

2. Solar Power System consists of an array of solar modules that are connected in series and parallel. The electricity generated is fed into a Solar CPU. The solar CPU does the following functions :
a. Converts the power from DC to 230V ac to run various loads like lights , fans , PCs , Printers , TVs , Mixers , Microwave and sometimes even ACs.
b. Has an inbuilt MPPT to maximize the available solar power
c. It applies the following logic – firstly, takes the solar generated power directly to run the loads on the solar power in the day time and secondly store the excess solar generated power in batteries.
