Solar Energy
Solar energy is a clean and renewable source. It has many benefits over electricity comparing to power plant diesel generators, which does not need regular provision of fuel. Solar panel can be installed in many sizes from home to industrial system and can be used for tropical to desert environments.
Polycrystalline Silicon Panel
Polycrystalline silicon panels are the most commonly used that offers better cost efficiency and low maintenance cost compared to other types of silicon solar panels. Consisting of many individual PV cells, each individual cell is isolated, making it possible for replacement of a damage independent cell without the need to replace the entire panel.
String Ribbon Silicon Panel
String ribbon silicon panels are made in a similar way as the polycrystalline silicon panels, resulting in almost the same electricity return rate of 12% to 14%. Unlike polycrystalline silicon panels, string ribbon silicon panels are made of PV cells fabricated in silicon strips bonded to metal bars to form a cell.
Amorphous Silicon Panel
Amorphous silicon panels are made of amorphous silicon without the crystal structure found in crystalline silicon. They are the most cost efficient, compared to other solar panels. However, they have the lowest electricity return rate of about 5%-6%. Typical applications include home and office equipments, telemetry, telecommunication, solar powered transport, solar generation systems, traffic systems and lightings, and many more.

Battery News
Electronic manufacturers should consider what truly is the heart of most of their portable devices - the battery. The size, shape, weight, and function are all directly related to the battery that will power them. The battery also provides an essential backup on printed circuits and computer systems. It seems that just about every six months a new battery technology emerges using much more exotic and expensive materials. Think about what the cell phone has become as a direct result of the size and capacity of the batteries powering them. Each successive improvement makes batteries smaller, able to hold a charge longer, and able to charge faster. This article takes a look at some of the new battery technologies and how they will improve the electronics industry.
Latest Developments
Sanyo introduced the new "eneloop" battery, which is a rechargeable NiMH battery useable right off the shelf. Unlike previous rechargeable batteries, which have limited shelf life because of their rapid discharge, these batteries retain 85% of their charge even after one year. Because this battery can be used for thousands of charges and is easily recycled, it is much more convenient, cost-effective, and eco-friendly than the traditional single-use batteries.
