Photovoltaic Solar Systems and Solar Panels
Information about solar energy, power inverter, photovoltaic modules, utility metering and batteries.

The Sun's radiant light is energy that can be converted into electrical energy.

The least expensive solar cells today are made using thin films of cadmium telluride. The typical cadmium telluride cell converts solar energy into electricity with 10 percent efficiency at a cost of about $4 per watt.

Photovoltaic Solar Panel Orientation
The power output of the photovoltaic solar panels is, of course, affected by their orientation and their tilt angle to the sun. This will vary depending on the time of year. A solar system can be most efficient if the tilt angle can be changed for seasonal sun movement.  The best tilt angle is usually equal to your latitude. For example, at latitude 38 ° and if solar panels are tilted at 38 ° they would be perpendicular to the sun twice a year between equinoxes.  The chart on the right will help to determine efficiency percentages with varying tilt angles and orientation. 		Photovoltaic solar panels made from crystalline silicon can produce energy for between $2.25 and $3 per watt. CIGS on glass panels can drop that cost to $1.50 per watt, but, solar energy will not be able to compete with fossil fuel–based electricity until it costs less than $1 per watt.

A number of 1.0 on the chart is the most efficient.

Silicon wafer–based solar cells, which account for 90 percent of installed solar capacity, are more efficient, converting up to 20 percent of the sun's energy, whereas thin-film cells generally convert only about 10 percent. This gap is expected to close over the next few years, making thin-film cells—which cost half that of silicon-wafer cells.


A typical solar cell has an efficiency of 15 percent—about one sixth of the sunlight striking the cell generates electricity.
Photovoltaic solar panels made from crystalline silicon can produce energy for between $2.25 and $3 per watt. CIGS on glass panels can drop that cost to $1.50 per watt, but, solar energy will not be able to compete with fossil fuel–based electricity until it costs less than $1 per watt.

Claims of development for a prototype that converts at 16.5 percent efficiency. IBM's CIGS technology—for copper, indium, gallium and selenide—is a thin-film approach that will initially be able to convert at least 15 percent of the solar energy it receives into electricity.  That compares with 19.9 percent efficiency of CIGS thin-film solar cells.

Solar panels are groups of solar modules connected electrically to generate direct current electricity at the desired voltage and current. Panels are installed on rooftops or open areas, such as parking lots or fields that have full sun exposure. (Solar panels can collect solar energy on cloudy days.) A larger grouping of solar panels constitutes a “solar array.” Large non-residential solar facilities often contain multiple arrays, sometimes located on different buildings at a given site.
The inverter transforms direct current electricity produced by the solar panels into alternating current (AC) electricity--the form of electricity used by most standard lights, motors, computers and air conditioners. The inverter also provides safety functions such as automatic shutdown of the solar electric system in the event of a power failure.
The Sun's energy reaching the surface of our planet is roughly 1 kilowatt per square meter.   Before entering our atmosphere it is about 20% more: 1.2 kilowatts.  At 15% efficiency 10 panels each measuring 1meter by 1 meter would power 1 1/2 bars on an electric heater.  20 panels would power an electric kettle (when the sun is shining).


  Building integrated photovoltaic solar system is a new conception in field of solar generating electricity application, which is perfect combination between solar photovoltaic and modern construction. The electricity can be provided by photovoltaic modules that lies out on the external surface of constructions to build green house, which is the integrated constructions of solar power system/roof/skylight and screen wall.
