The evening of 6 may, the world of light rain, the author came to Jiaojiang pepper light group, the plant within 3 all of the use of solar LED (semiconductor light-emitting diode) lights, as the whole plant as the day. < p > jiaoguang Group Chairman Zhu Jie min, according to reports, the lights of the street lamp power are 80 Watt, brightness equivalent to now the road 400 Watt High pressure sodium lamp, also due to the use of solar, no a penny of the cost of energy consumption. According to estimates, if use three street lamps 400W high pressure sodium lamp, every year to more than 2600 kwh of electricity consumption and cost nearly 2000 yuan, and for solar LED annual carbon dioxide emissions 2041 kg. The completion of the solar project to start, to promote energy conservation in Jiaojiang area, the road to low carbon economy and green development has a demonstration significance.

solar energy as an unlimited renewable energy, and gradually replace some of the city's production and living of conventional energy is the trend. And LED lighting is internationally recognized as a new generation of solid-state lighting light source, with energy saving, high efficiency, long life, green environmental protection, no radiation, and other notable features, its power consumption is only one tenth of the incandescent lamp, one third of the fluorescent lamp, life is up to 1 00000 hours, is 50 times that of ordinary incandescent lamp life, 20 times the service life of fluorescent lamp, it is following the incandescent lamp, fluorescent lamp, gas discharge lamp after the fourth generation lighting products.

"this solar panel power can reach 115 watts." Zhu Jiemin pointed to the company has just developed a size of 120 cm x 80 cm solar panel said. The solar panels a day cumulative power can drive 80 watts of power LED (light emitting diode) lighting lighting 5 all night, record reached 17 night, light also keep bright, to solve the winter, cloudy, snow and other inclement weather conditions of solar lighting problem.

< p > the showroom to see, solar LED lights by solar panels, control box, maintenance free battery, constant current driver, LED lamp and road lamp pole. The working principle, using light voltaic effect made solar panels solar radiation received energy and transformed into electrical energy output, after the charge and discharge controller storage in the battery, night when the light intensity is reduced, panels open voltage 4.5V around, the accumulator is used to start the lamp head discharge.

now, the most critical is the issue of solar power." Zhu Jiemin hope that the government introduced the relevant policies as soon as possible, to solve the problem of solar energy household. It is reported that in general, solar power for DC power, if it is to be incorporated into the power grid, through a series of procedures, of which the key is first converter to solar radiation is converted to DC, and then through the device to the alternating current direct current is transformed into, finally change the input voltage of power grid.

how to change the voltage? Transmission to the power grid after how to calculate the price? Government subsidies? At present, these issues are subject to a special study.
