Introduction – Why Solar? Natural disasters such as hurricanes, tornados, floods, and powerful storms often occur with little warning, and can be as destructive as Hurricane Katrina (2005), Hurricane Irene (2011) or Hurricane Sandy (2012). Sandy left 8.5 million people across the East Coast without power, adding further challenges to disaster relief efforts such as …
Introduction The development of silicon photovoltaic (PV) cells as renewable energy sources and batteries as energy storage devices allowed for the construction of charging stations and/or solar chargers with energy storage devices/battery banks. Figure 1a presents a general scheme of connections between the solar panel and a storage unit. From the point of view of …
MIURA FOLDING PATTERN Origami, as the art of paper folding originated from Japan, has intrigued many artists,hobbyists, and scientist. Origami techniques have been utilized in many industrial applications such as: Architecture, Packaging design, Solar panels, Space telescope, Eyeglass, Origami stents for medical purposes, Origami grocery bags. The Miura folding pattern has the ability to compact …
Introudction Batteries are nowadays the main energy provider to portable devices. They are used for their high power density and ease of use. Their disadvantages, however, limit their application. Their energy density can drop to as low as 200Wh/kg and their technology seems to improve slower than do other technologies . The charging circuits are …

Charge Controller Fig. 1 shows the intended charge controller circuit which is used to charge the 12V battery. This design is a simple linear regulator. Although it does not have a low voltage disconnect, it can prevent over charging of the battery by automatically reducing the charging current to a low level whenever the battery …
The proposed system uses a solar panel as the main source to get electricity. The solar panel gets the energy from the sun. It also calls the photovoltaic effect, this process causes electrons to become quite disrupted from their normal atomic orbit. This action alone creates an electrical power in the panels (also called DC), …
