Solar Photovoltaic Panels - An Introduction
Solar pv panels, also called solar photovoltaic panels or
solar electric modules,
generate power when exposed to high levels of light. The
effect was discovered in 1839 by nineteen-year-old Edmund
Modern solar pv panels were first
developed commercially for NASA and the space race in the 1950's. With
no moving parts, solar pv is a silent and reliable method of
in remote locations.
Top quality solar modules have
power performance warranties of 20 years, with an
expected life of 60 years or more. An early commercial solar pv
system, now 46 years old, is still producing power within warranty
pv panels are currently available in three main
Monocrystalline solar cells are the most efficient and also the most
expensive. Polycrystalline or multicrystalline solar cells are almost
as efficient as mono cells and are less expensive to manufacture.
solar pv modules are the most cost effective technology. These modules
perform better than the other types in cloudy conditions, however they
are less efficient and therefore require more installation space.
How do solar panels work ?
Latest Solar PV Industry News
the last few years the solar pv industry has seen a huge growth. The
feed-in-tariffs (FiTs) in Germany, Spain and more recently in the UK,
have helped to create buoyant markets and inflate demand.
In 2008, worldwide module production increased 80% on the
previous year. In 2009 worldwide production grew by 60%. As a result of
the global economic slowdown and decreasing production costs, module
prices are now at an all time low.
The price of solar pv has also been compounded by the recent
Spanish reduction of their FiT rates, leaving many European
manufacturers with cancelled or postponed orders.
Across the industry, many manufacturers have now signed up to
PV Cycle, a mechanism designed to ensure that when modules reach the
end of their life, they are easy to recycle.
Recent Solar PV Technology Developments
Sunpower's 'back-contact' cells are now hitting 21.5 %
efficiency and the latest Sanyo
HIT (hybrid monocrystalline & amorphous) solar pv panels are
giving power outputs of approx. 200w per m2 in good sun.
Nanosolar have been developing
printed solar cells, using a nano particle ink.
Printed solar cells offer the chance to massively reduce the cost of pv
manufacturing. Nanosolar have recently launched their product on the
market, although prices are still high.
Meanwhile, biological solar pv materials are being developed
by Biosolar -
reducing the need for petroleum-based
plastic solar cell components.
Flexible and folding solar panels have been on the market for
while, offering convenience, portability and ease of fitting. Popular
in the leisure and marine markets, flexible solar pv panels need to be
well designed and robustly constructed to withstand regular movement.
Off-Grid Solar PV & Wind Power Applications
At the EDC we supply commercial, industrial and domestic
off-grid solar pv systems. This covers a diverse range of
applications including remote
communications and off-grid
Solar panels are also ideal for mobile battery charging
use in boats,
and caravans. Solar panels extend the life of most battery based
power systems, as batteries like being on a regular charge.
