Some reasons for solar power
With a solar power system on your roof you replace other energy sources such as gas, coal or uranium and thereby reduces ecological damage by eliminating CO2 emissions. Every kilowatt hour generated by solar energy means a reduction in pollutants.
Please do also take into consideration also all of the emissions which are incurred along the way, ranging from extracting the raw material to burning the fossil fuels in furnaces. Among the polluters contributing to such emissions can be counted crude oil vessels used for the transport, refineries for processing the oil, road tankers for transporting heating oil to consumers and any material related emissions which are incurred during the production of the different conversion systems.
Solar energy is infinitely renewable: The sun is guaranteed to be available as the largest and most reliable source of clean and free of cost energy for some billions of years to come. Solar energy is used directly on location. There are no transport costs and no appreciable conduction losses. The technology of Heckert Solar's crystalline high performance modules is fully developed and subject to only minor improvements.
Solar power systems represent quality of life, demonstrate environmental consciousness and enhance the value of your real estate. In the framework of incrasing energy costs they save money.
At the latitude of Germany e.g. a rough rule of thumb is an energy yield of approximately 900 kWh per kWp of installed performance for a system and year. Kilowatt peak (kWp) is the measuring unit for the peak performance of a photovoltaic generator under standard test conditions. A 2 kWp photovoltaic system approximately 20 square meters in size is thus able to produce approximately 1800 kWh of solar energy annually.
As soon as a solar power system starts producing more energy than was required in the form of fossil fuels to produce it, setting up such a system makes sense both ecologically and economically. The energy return time of solar power systems specifies the period of time in which a system has to be in operation in order to produce the amount of energy that was required for its manufacture. Nowadays one can assume an energy return time of approximately three years which is very good value considering that a solar power system has a long economic life-time of between approximately 30 and 40 years.
