Photovoltaic (PV) solar energy is the conversion of
sunlight to electricity. It is versatile, modular, reliable,
yet a simple source of power. Photovoltaic equipment generates
electricity without burning any
fuels, making any noise, and is completely pollution free.

Photovoltaics
Larger photovoltaic installations
currently provide electricity for homes and commercial buildings,
but there is also an increasing tendency to use smaller systems
to provide electricity for pumps, road signs, telephone boxes
and streetlights. An innovative approach to their use and rapidly
developing technology will be the key to its success.
At a simple level, photovoltaic
cells convert sunlight directly into electricity by the interaction
of photons and electrons within a semiconductor material. To create
a photovoltaic cell, a material such as silicon is doped with
atoms from an element with one more or less electrons than occurs
in its matching substrate (e.g., silicon). A thin layer of each
material is joined to form a junction. Photons, striking the cell,
cause this mismatched electron to be dislodged, creating a current
as it moves across the junction. Through a grid of physical connections,
the current is gathered. Various currents and voltages can be
supplied through series and parallel arrays of cells.

Thermal
Solar Thermal systems collect
the heat from sunlight to produce hot water, heat, or electric
power. Solar Thermal differs from Passive Solar in that a mechanical
device distributes the heated water or air throughout the building.
Solar Power water heating systems
are the most popular form of solar energy. Low-temperature systems
are installed on roofs which are preferably south facing and the
system is then connected to the hot water system. Medium temperature
systems heat either air or liquid as a heating conductor and are
used to provide space, water, and process heating. These usually
consist of flat-plate collectors: large, flat boxes that are dark
inside, with one or more glass covers.
