AC Solar Generator

Goal

Generate alternating current (AC) electricity directly from photovoltaic cells without the need for DC-to-AC inverters.

Problem

Solar panels produce DC power that must be converted to AC for grid use, adding cost, losses, and complexity.

Concept Summary

The invention uses pairs of solar cells wired anti-parallel and a rotating segmented disc that alternately shades and exposes each cell in a pair. As one cell is illuminated and the other is shaded, the voltage polarity switches, producing a sinusoidal AC output. The disc is driven by a small DC motor powered by auxiliary solar cells. The system can be scaled to single-phase or three-phase AC and tied directly to the grid.

Principles

• Mechanical shading of photovoltaic cells
• Anti-parallel cell wiring
• Rotating segmented disc to create alternating exposure
• Phase synchronization via motor control

Scientific Domains

Materials
