ABSTRACT
A solar array power generation system includes a solar array electrically connected to a control system. The solar array has a plurality of solar modules, each module having at least one DC/DC converter for converting the raw panel output to an optimized high voltage, low current output. In a further embodiment, each DC/DC converter requires a signal to enable power output of the solar modules.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The subject disclosure relates to systems for utilizing power generated by solar panels, and more particularly to an improved system for converting the power generated by a solar panel to improve safety and efficiency.

2. Background of the Related Art

In the modern world, the needs for electrical power are ubiquitous. However, many of the sources of electrical power such as nuclear energy and coal or fossil fuel power generation plants are not always feasible, and generate not only power but excessive polution, exhaustion of resources and controversy. In an effort to avoid these drawbacks by utilizing the renewable energy of the sun, photovoltaic solar panel arrays are finding expanded use in the home environment and industry. Solar panel arrays are particularly well-suited to stand alone applications in isolated regions. Solar panel arrays not only function as an alternate energy source but excess power can be sold back to utility companies or stored for later use.

REPRESENTATIVE CLAIMS

What is claimed is:

1. A system comprising:

a plurality of solar panels; and

a plurality of DC/DC power converters, each DC/DC power converter of the plurality of DC/DC power converters being connected to a respective solar panel of the plurality of solar panels; and

a central control system configured to generate a control signal, wherein each DC/DC power converter of the plurality of DC/DC power converters is configured to vary its mode of operation in response to receiving the control signal.

2. The system of claim 1, wherein each of the DC/DC power converters is configured to perform maximum power point tracking (MPPT).

3. The system of claim 1, wherein the central control system comprises a DC/AC inverter connected to the plurality of DC/DC power converters.
