Abstract

Solar panels with an integrated DC-to-AC converter are provided. Such solar panels are usable as an independent generator of AC power or as part of an array of panels, and may be grid-connected with low initial cost of entry. Other aspects provide a panel with a built-in array of “micro-batteries” for energy storage in off-grid applications or grid-connected. Also provided herein, in another aspect, is an AC solar panel whose internal design and structure is optimized for the generation of AC power. Intrinsically, this includes an embedded DC-to-AC converter or converters. The AC solar panel may be used as an independent generator of AC power or as part of an array of panels. In still further aspects, one or more panels may be used as a remote AC power source with after sun-down power generation capability, low initial cost of entry and ease of deployment.

Claims

1. A modular solar system, comprising:

at least two solar panels, each panel comprising;

a solar power generator;

a DC-to-AC converter; and

a control circuit that regulates output from the DC-to-AC converter,

wherein the at least two solar panels are interconnected to provide a combined power output that is regulated by the control circuit of each respective panel, and wherein at least an additional panel may be interconnected to the at least two solar panels after the at least two solar panels have been in operation.

2. The modular solar system, as claimed in claim 1, further comprising:

an impedance measurement circuit that is interconnected with an output of each panel; and

a control circuit interconnected to the impedance measurement circuit that provides power to the output of the panel when it is determined that the impedance measured by the impedance measurement circuit is within a predetermined range of impedance measurements.

3. The modular solar system, as claimed in claim 1, wherein at least one of the solar panels further comprises:

at least one battery that is charged by the solar power generator and provides power to the DC-to-AC converter when the solar power generator is not providing power.

4. The modular solar system, as claimed in claim 1, wherein the control circuit in at least one panel includes a communications portion and the power generated from the panel is provided according to information received at the communications portion.
