10 Good Reasons to Change to Solar Photovoltaic
'Photovoltaic' is a marriage of two words: 'photo', from Greek roots, meaning light, and 'voltaic', from 'volt', which is the boss bv9990 player used to measure electric potential at a given point.
Photovoltaic systems use cells to convert solar radiation into electricity. The cell consists of the layers of a semi-conducting material. When light shines relating to the cell it creates an electric field across the layers, causing electricity circulation. The greater the intensity within the light, the more flow of electricity is.
The most common semi conductor materials in photovoltaic
cells is silicon, an element most commonly found in sand. There is no limitation to its availability as a raw material; silicon is the second most abundant material in the earth's mass.
A photovoltaic system therefore does n't have bright sunlight to be able to operate. It in addition be generate electricity on cloudy days. As a result of reflection of sunlight, slightly cloudy days can even induce higher energy yields than days by using a completely cloudless sky.
1 The fuel is free.
The sun is the only resource needed to power solar panels.
And the sun will keep shining until the world's end. Also, most photovoltaic
cells are created from silicon, and silicon is an abundant and nontoxic element (the second most abundant material in the earth's mass).
2 It produces no noise, harmful emissions or polluting gases. The burning of natural helpful information for energy can create smoke, cause acid rain, pollute water and pollute the air. Carbon dioxide CO2 , a number one greenhouse gas, one other produced.
Solar power uses only the power of the sun as its fuel. It creates no harmful byproduct and contributes actively in order to the global warming.
3 PV systems are very safe and highly reliable.
The estimated duration of a PV module is 30 countless. Furthermore, the modules' performance is quite high providing over 80% of the initial power after 20 years which makes photovoltaics a very reliable technology in the end. In addition, very high quality standards are set at an European level which guarantees that consumers buy reliable products.
4 PV Modules can be recycled and therefore are usually used in the development process (silicon, glass, aluminium, etc.) can be reused.
Recycling is not really beneficial for the environment but also for helping to reduce the energy needed to generate those materials so the cost of manufacture.
5 It requires low maintenance.
Solar modules are almost maintenance-free and provide an easy growing.
6 It brings electricity to remote rural areas.
Solar systems give an additional 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.
7 It could be aesthetically integrated in buildings (BIPV).
Systems can cover roofs and facades contributing to reduce the energy buildings consume. They don't produce noise and could be integrated in very aesthetic ways. European building legislations already been and are being reviewed to make renewable energies as a required energy source in public and residential buildings. Until is accelerating the development of ecobuildings and positive energy buildings (E+ Buildings) which reveals many opportunities to secure a better integration of PV systems in the built environment.
8 The energy pay-back time regarding a module is constantly decreasing. This suggests that the time deparately needed for a PV module to produce a lot energy as it requires be manufactured really short, it varies between 1,5 years to 3 seasons. A module therefore produces 6 to 18 times more energy than has to manufacture it.
9 It creates thousands of opportunities. The PV sector, with an average annual growth of 40% during previous years is increasingly contributing to the development of thousand of jobs in Europe and worldwide.
10 It contributes to improving the security of Europe's 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 had to be converted by PV modules. Therefore Photovoltaics can play a crucial role in improving the security of Europe's energy supply.
