While the oil, gas and coal reserves continue to decline, photovoltaic is developing from a niche application to an alternative to conventional energy production that is used throughout the world, providing a growing share of the power supply. In the long term, solar energy is the best answer to the greenhouse effect, which forms one of toady’s greatest threats to mankind. This global warming is exacerbated by carbon dioxide (CO2) which is generated when coal, gas and oil are burned. The consequences are extreme weather conditions, such as torrent-like rain, heat waves, drought periods and thunderstorms. The number of natural disasters of this kind has increased and caused more human loss and material damage during the past years than ever before. This protection action of the environment is also financially profitable. As many countries has established all sorts legislations and policies to encourage people use and buy renewable energy.

10 GOOD REASONS to switch to solar photovoltaic electricity

• The fuel is free.The sun is the only resource人needed to power solar panels.It produces no noise,And the sun will keep shining until the worlds end. Also, most photovoltaiccells are made from silicon, and silicon is an abundant and non-toxic element (the second most abundant material in the earths mass)
• It produces no noise, harmful emissions or polluting gases.The burning of natural resources for energy can create smoke,cause acid rain,pollute water and pollute the air.Carbon dioxide CO2,a leading greenhouse gas,is also produced.Solar power uses only the power of the sun as its fuel.It creates no harmful by-product and contributes actively to reduce the global warming.
• PV systems are very safe and highly reliable.The estimated lifetime of a PV module is 30 years. Furthermore, the modules performance is very high providing over 80% of the initial power after 25 years which makes photovoltaics a very reliable technology in the long term. In addition, very high quality standards are set at a European level which guarantees that consumers buy reliable Products.
• PV Modules can be recycled and therefore the materials used in the production process (silicon, glass, aluminium, etc.) can be reused. Recycling is not only benecial for the environment but also for helping to reduce the energy needed to produce those materials and therefore the cost of fabrication. More information is available on the following website: www.pvcyle.org
• It requires low maintenance.Solar modules are almost maintenance-free and offer an easy installation.
• It brings electricity to remote rural areas.Solar systems give an added value to rural areas (especially in developing countries where electricity is not available). House lighting, hospital refrigeration systems and water pumping are some of the many applications for off-grid systems. Telecommunication systems in remote areas are also well-known users of PV systems.
• It can be aesthetically integrated in buildings (BIPV).Systems can cover roofs and facades contributing to reduce the energy buildings consume. They dont produce noise and can beintegrated in very aesthetic ways. European building legislations have been and are being reviewed to make renewable energies as a required energy source in public and residential buildings. This fact is accelerating the development of ecobuildings and positive energy buildings (E+ Buildings) which opens up many opportunities for a better integration of PV systems in the built environment.

• The energy pay-back time of a module is constantly decreasing. This means that the time required for a PV module to produce as much energy as it needs to be manufactured is very short, it varies between 1,5 years to 3 years. A module therefore produces 6 to 18 times more energy than is needed to manufacture it.
• It creates thousands of jobs. The PV sector, with an average annual growth of 40% during the past years is increasingly contributing to the creation of thousand of jobs in Europe and worldwide.
• It contributes to improving the security of Europes energy supply In order to cover 100% of the electricity demand in Europe, only the 0.7% of the total land of Europe would be needed to be converted by PV modules. Therefore Photovoltaics can play an important role in improving the security of Europes energy supply
