A solar inverter is really a converter, though the rules of physics say otherwise. ) Most homes use AC rather than DC energy. It's a device that converts direct current (DC) electricity, which is what a solar panel generates, to alternating current (AC) electricity, which the electrical grid uses. In solar PV systems—especially grid-tied systems using modern inverters—understanding the balance between active and reactive power is essential. . Solar energy can be harnessed two primary ways: photovoltaics (PVs) are semiconductors that generate electricity directly from sunlight, while solar thermal technologies use sunlight to heat water for domestic uses, to warm buildings, or heat fluids to drive electricity-generating turbines. Sumanth Lokanath, Proceedings 2017 PV Reliability Workshop, March 2017. DC energy is not safe to use in homes.
