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.

Solar Panels
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.
