What does the "40WP" in the technical parameters of the solar LED courtyard lamp mean?
Solar LED courtyard lamp technical parameters in the 40WP is representative of solar cells, the maximum output power of 40.
Solar garden lamp uses solar energy to the solar radiation energy, the solar panel to recharge the battery, the battery at night to use power supply of light source lamp, without complicated and expensive pipeline laying, adjustable lighting layout, safety and energy saving and no pollution, charging and on / off process using intelligent control. The automatic light control switch, without manual operation, stable and reliable operation, save electricity, maintenance free.
The unit of output power of solar cells in standard sunlight. The European Commission defines the 101 standard, the radiation intensity 1000W/m2, the atmospheric mass AM1.5, the battery temperature 25 degrees, the output power of solar cells.
Wp is the abbreviation of solar cell peak power, that is, Wp=Wpeak, each day with the sun's angle is different, the output power is also different. Maximum output power expressed by Wp.
