photovoltaic module
The solar photovoltaic produces electricity from sunlight through sensors consist of electronic components. Not to be confused with solar thermal, which produces only heat. This method applies to individual housing as well as collectively. The electricity generated can be consumed (for a remote site) or resold in whole or in part, to your power company (the most advantageous).
An ecological approach
Solar energy is a renewable energy available, free and easy to turn while the fossil fuels (oil, gas, coal) are being depleted, are becoming more expensive and emit greenhouse gases. During operation, the production of photovoltaic electricity has no impact on the environment (or noise, or electromagnetic or chemical pollutants or waste). The only impacts on the environment are at the stage of the manufacture of sensors (Energy consumption and generation of waste to be reprocessed).
Technology mastered.
The photovoltaic capture techniques are now well developed, in progress and less maintenance (lifetime of at least 25 years). A solar photovoltaic system includes at least the following:
solar light converts energy into electric current continuous
an inverter converting direct current into alternating current similar to that of network
two counters for current measurement, one for selling and one for the purchase
Photovoltaic solar panels can also be deployed in industrial small
The sensors consist of photovoltaic modules made of crystalline silicon, and presenting usually in the form of rectangular panels with a surface area ranging from 3 m2 to 50cm2 and a few millimeters thick. They can be added to the building or better integrated into its structure (facade, roof). For optimum performance, panels should be inclined at 45 degrees and face south. A sensor surface of 30 m2 roof will produce about 3000 kWh / year of electricity to meet consumption needs of an average household (excluding heating, hot water and cooking)
The inverter is in the form of a box, set near the sensors. It allows the connection with the network operator or other power. It also contains safety devices by cutting the power when the network is turned off.
In the case where the current is not fully paid to the network, it requires the addition of batteries to store electricity.
Simplified administrative procedures
Administrative procedures relating to the implementation of solar panels on an existing dwelling of less than 12m in height, are summarized with a simple statement of work in town hall (the solar panels that are not floor area). In the case of locating a new building it is preferable to integrate the modules in the building permit.
A worthwhile investment
Without public support, investment in a photovoltaic system would hardly be profitable for an individual as the cost of a photovoltaic is about to 20,000 dollars. The vast bulk of the cost consists of photovoltaic sensors. Also the state and some local governments offer these grants and subsidies: the redemption price of electricity up to 5 times the market price, tax credit of 50%.
The profitability of the operation is carried out after about 10 years. Technology continues to evolve, and we can reasonably expect to grow sales significantly lower the manufacturing costs of the sensors.
Conclusion
Produce its own electricity from photovoltaic solar radiation is now a viable and accessible to all those involved in renewable energy and conscious of environmental problems today.
