Abstract: A portable modular solar power system generates electricity from sunlight to charge a battery and provide power to a load. Specifically, the portable system includes a load receiving the electrical power, and a portable modular solar power apparatus that includes a photovoltaic panel converting the sunlight to the electrical energy, a battery connected to the photovoltaic panel and receiving an electrical charge from the photovoltaic panel, and providing the electrical power to the load connected to the battery, and a lightweight frame housing the battery and having the photovoltaic panel connected thereto. The lightweight frame includes a battery tray supporting the battery and providing self ballasting for the portable modular solar power apparatus, and at least two adjustable telescoping legs providing support for the portable modular solar power apparatus and allowing for adjustments to an angle of the photovoltaic panel with respect to receipt of the sunlight.
