Who its power from a solar installation which does not have to fear inflation. But what are the disadvantages and advantages of solar energy?

The more energy prices rise, the more attractive is the production of electricity on their own. Solar panels on the roof or in the garden and also promised free clean electricity produced from solar radiation. But the investment is effectively connected to a photovoltaic system for the conversion of light? What are the disadvantages and advantages of solar energy?
On the border of the sun rays hit Earth’s atmosphere with an energy of 1.367 kilowatts per square meter. On the way to Earth’s lost most of it. It is reflected by suspended particles such as dust or ice crystals and converted into heat. The only ten percent of the radiation reaching the ground could still meet the energy needs of the people. But who wants to use the power of light itself, should weigh the disadvantages and advantages of advance solar energy exactly. For the energy source, although emission and free, but requires a lot of space in return and expensive technology.

Solar energy is free and clean

The sun is available an inexhaustible and free energy source. This is probably the biggest plus, considering advantages and disadvantages of solar energy. Who his own power from the solar system they are required to price increases in the provider no longer fear so.

The investment in a photovoltaic system is not irrelevant, but is subsidized by the government. It is based on the Renewable Energy Law. However, the subsidy is expected the technology to Germany. Already, according to a balance sheet of the Green Group in the Bundestag in the solar industry more than 60 000 people in more than 100 companies employed who are involved in the planning, construction and installation of photovoltaic systems. The turnover of the sector in Germany is ten billion euros, of which two thirds of the remaining value in the country and bring the federal tax revenue by year three billion euros in taxes.

An important point from the disadvantages and advantages of solar energy is definitely the climate. According to the study could in this way, the emission of carbon dioxide in 2009 alone 3.6 million tonnes to be reduced. Because with the energy or particulate matter and greenhouse gases.

Solar energy the costs for all

Solar radiation is not continuous, and not to the same intensity available. It depends on the weather, time of year and time of day. Without the technology to store that is not a constant energy supply is possible.

Until the solar systems alone provided the same amount of energy, has been the need to take their production, depending on the technology from 1.5 to 3.5 years. This has the Energy Research Centre of the Netherlands is calculated in a study. However, photovoltaic systems with up to 40 years durability.

The result is clear when comparing the advantages and disadvantages of solar energy from the cost factor. Since the photovoltaic cuts off badly, because according to the Renewable Energy Act, the additional cost of generating solar power on all German consumers folded. And they are 40 to 50 cents per kilowatt hour considerably. Electricity from wind power costs, however with 6 to 8 cents per kilowatt-hour about the same as that produced in traditional power plants.

Although the proportion of solar power in the German energy consumption with only about one percent of all Germans have this deep into their pockets. The calculations of the Rhine-Westphalian Institute for Economic Research, the promotion of solar energy has already cost taxpayers 14.3 billion euros. The solar magazine Photon goes from 77 billion euros.
