AC Solar Generator

[Category : - RENEWABLE ENERGY]
[Viewed 4955 times]

A device, system and method for generating alternating current (a/c) electricity directly from photovoltaic cells utilize an array of photovoltaic cell pairs that are each connected in anti-parallel to form an a/c junction. The system, device and method mechanically gradually exposes and shades photovoltaic cell pairs to sunlight to generate alternating current electricity at an a/c junction of the solar cell pairs. Gradually and alternately exposing and shading the two anti-parallel connected solar cells of each solar cell pair causes the amplitude and polarity of the electricity at the a/c junction to gradually rise and fall to produce alternating current electricity. The gradual, alternating exposure and shading of the two anti-parallel solar cells is accomplished by mechanically covering and exposing the solar cell pairs.
This is efficiently accomplished by a rotating segmented disc positioned over an array of solar cell pairs.

Financial information

Summary

The AC Solar Generator (ACSG) is a device that will produce AC current directly from solar cells without an inverter. The ACSG produces a pure sine wave that matches commercially produced utility power. Simply input a signal from the power source to be matched and it will align with the phase, regardless if it is 50 or 60 cycles through a
phase synchronizer that is incorporated into the device. The ACSG has single or three phase capabilities.

How It Works

The ACSG works on the same principle as any regular generator except it is completely solar powered. Solar cells on the perimeter, power a DC motor that spins the disc. The disc speed is regulated by a phase synchronizer, which adjusts the motor speed to match any input phase signal. AC current is directly created when the cells are alternately exposed to light, by the circulating disc through our patented system. No inverter, batteries or heavy wiring are needed.

Application

We believe the ACSG has multiple applications. The ACSG is designed to be a supplemental power system for residential, commercial, or to input power to the grid system. Multiple ACSGs could be assembled in a modular pattern to create the most efficient sized panels. We believe the units could be sold in a “carry out” version from retail stores for consumer use. Commercial projects could be designed and installed to supplement power for commercial and manufacturing facilities or for solar power generating stations providing power to the grid system. With single and three phase capabilities, all of this is very feasible.

Design of ACSG

Our twelve inch prototype proves all our theories and that our patented system is feasible, but we do not have a production ready product. While our prototype demonstrates the basic principles of the ACSG, some of the items needed to complete the final ACSG are environmental protection, cell type, cell size, motor system and other production ready design elements. Once those items are determined, the optimal modular size, output,
cost, comparison of each unit and the combined units would be more easily determined.

Comparison AC & DC Solar

While exact costs are unknown at this time, these are facts we do know:

• Current solar power systems require batteries, which adds to the cost of
installation and maintenance.
• Inverters to convert battery stored solar DC power to AC power add to
installation costs and maintenance costs for the life of the system.
• Heavy gauge wire is needed to carry DC current.
• The ACSG directly produces AC current eliminating the need for any inverters.
• The ACSG doesn’t require batteries which saves costs, but can only produce AC
when exposed to light.
• AC can be transmitted on smaller gauge wire, saving installation costs, as well as
further distances than DC.
• While the ACSG has a moving part, we feel this could be made to last many years
with easily replaced parts.
• While unknown at this time, we believe the final costs for ASCG to produce
power will far exceed existing systems.
