Generate with solar photovoltaic
Feed after the Renewable Energies Act (EEG)
Despite the fall in Solar Products grid is still interesting. Two options are available.
The Renewable Energies Act (EEG) now offers two interesting possibilities of the grid for photovoltaic systems that are not larger than 30 kWp and are on or near buildings are:
Feed
As in the Renewable Energies Act (EEG) is fixed, is the feed for the kilowatt-hour of Solar Lighting at 43.01 euro cents dropped. This price is for 20 years guaranteed by law, as in past years .. Due to the decline in purchase price for solar power, there were now doubts whether a photovoltaic system is still worthwhile. But the concern is unfounded.
The price for a photovoltaic system this year have been lower. So far have had for 10 square meters of photovoltaic systems around 4,500 euros in costs can be expected. The price is now only about 4,000 euros for 10 square meters of photovoltaic systems ..
Even consumer price of the Renewable Energies Act (EEG)
Now, there is even used for electricity produced from photovoltaic installations compensation. This is even more interesting than the previously valid feed. For each course used kilowatt hour from your own photovoltaic system will be 20 years paid 25.01 euro cents. Since no more electricity to be purchased will be around 20 euro cents per kilowatt-hour saved.
There is a refund of 25.01 euro cents. That is around 45 euro cents per kilowatt hour. As for this year (2009) already some electricity suppliers have announced a price increase, the self-consumption even more interesting than the usual Einspeisvergütung yet. This opportunity is suitable for homes as well as an interesting variant Spaces Energy Saving Appliances. Users are independent of the electricity price increases.
Conditions for the establishment of a photovoltaic system
The roof should be an orientation to the south have. The deviation from the south to be exact + / – 20 ° do not exceed. With roof slopes between 20 ° and 50 ° are good results. Ideally, a roof slope of 30 °. For both options, self-consumer tariff or feed, an additional meter installed.
Photovoltaic system with water cooling
With a slightly higher investment provides a photovoltaic system with water indicate a 30 percent higher electricity output per year as an air-cooled plant. Additionally, even hot water for hot water supply of the household produces. A generous buffer ensures the water supply even in largely poor sun times. Another advantage: This photovoltaic system can be used instead of a roofing systems.
VAT for commercial use
Solar operators who have their electricity into the grid, and tax law are treated as entrepreneurs. The value added tax from 19 percent to the investment were the operators from the tax refunded. For the self-use was the most unsettled Solar Panels. The Federal Environment Ministry now has a position: “The use of direct consumption does not affect the classification of a plant operator as an entrepreneur within the meaning of the Sales Tax Act” and “usually results in no financial deterioration for plant operators, for the supply and pay VAT by the possibility to make use of deductions. “

Origins, benefits and environmental performance of energy-saving bulb
A measure to limit CO2 emissions is, inter alia, the Power Saver. Using the Energy Efficiency lamp can also use any private person their part.
The fact that it comes to the CO2 budget of the earth is not well ordered, it is a fact that we no longer can crowd: the ozone hole is growing, the global climate heats up and the natural disasters are becoming more extreme proportions. Drought, heat and fire disasters, floods and so much hardship and suffering.
From the state, industry and economy, measures to limit CO2 emissions is required, must restrict itself but also any private person. A first step in this direction is the replacement of the 1877 Edison invented light bulbs by energy saving bulbs.
How energy-saving lamps are created?
They come in their way of 150 years ago invented fluorescent tube, the ancestors of today’s well-known neon light from. By Charging a mercury-gas mixture is free of ultraviolet light that passes through a fluorescent layer on the inside of the tube into visible Indoor Lighting is converted.
Lamps give their life in the 4 – to 5-fold amount of light from incandescent bulbs, so they quickly workshops, halls and storage rooms could conquer. For use in living rooms, the bluish light but can not establish. The recommended energy saving lamps nowadays are compact versions of fluorescent tubes. The light color can be the nature of the inner coating of the tubes be affected.
Environment by saving electricity: reducing CO2 emissions
Electricity is, inter alia by atomic fission nuclear, hydro or, as is often the proportion of the most common is through the burning of fossil fuels, extracted. Consume too much electricity does the environment to a large extent with the CO2, which is the combustion processes is to pollute.
An energy-saving lamps of 11 watts, a 60-watt light bulb to replace the interview, is required in its estimated life of 10,000 hours to about 735 kWh less power than the light bulb. Few people have a sense of what to produce that amount of electricity is needed: to 735 kWh of electricity needed to produce, for example in a coal-fired power plant 830 kg brown to 2100 kg of CO2 are burned, other byproducts of this process are also heavy metals such as mercury, sulfur dioxide and nitrogen oxides. Incidentally, can the average household 60 to 100 euros a year through reduced electricity bill saving Landscape Lighting.
Harmful substances
It is true that in energy-saving light bulbs that contain mercury is heavy. According to an EU directive may be a lamp up to 5 mg contain this poison. It is hermetically sealed container or incorporated in a mercury alloy. Even when an energy saving lamp breakage is no direct danger to the persons present, security is still advised in this case durchzulüften well.
Comparing the emissions of mercury for the production of electricity for Solar Lighting using incandescent bulbs, such as a coal-fired power plant, and the quantity of processed mercury in energy-saving lamps, this environmental assessment of mercury emissions even in favor of the new energy-saving light bulbs from.
Lack of information on the disposal
In industrial enterprises, 90% of Solar Tubes and energy-saving bulbs properly disposed of. Unfortunately, only 25% of households informed that energy saving light bulbs at the end of their lifetime to be given special, because only then can a large part of the raw materials contained recycled.
