Q:What are the forms of solar energy products
Solar hot water, solar photovoltaic power generation, various solar lamps
Q:Are solar panels now in use?
Generally through the position, speed and torque in three ways to control the servo motor to achieve high-precision positioning of the transmission system, the transmission technology is the high-end products.
Q:New solar productsI want to know the new solar energy
Their idea is to paint more than two kinds of dye in a certain proportion, and paint it on a special glass window. These dyes can absorb different wavelengths of sunlight, and then through the glass window to concentrate sunlight on the edge of the window solar cells. Solar cells convert light energy into electrical energy.
Q:Solar products must be in the sun
Other light sources can be used to meet the needs of the product (e.g., solar watches can be recharged by other light sources)
Q:Solar garden lamp product parameters
Rainy days guarantee: can work continuously for more than 15 rainy days (regional / seasonal different) (can be made on request)Without the need for laying underground cables, without payment of lighting, key components of solar panels, solar garden lights the solar street lamp intelligent controller, DC maintenance free storage battery and a lighting lamp through the national development and Reform Commission, the world bank /GEF/ photovoltaic products certification. The utility model is mainly suitable for the lighting and lighting of the city road, the small square, the industrial park, the scenic spot, the park green belt, etc..
Q:What are the solar products?
Solar energy power supply system for LED street lamp LED floodlightSolar lamp with LED outline lamp solar corridor lampSpecial lighting system for LED pulse cold light beauty lamp tent
Q:The steps of making solar technology stubs
Making method:1 at the end of the rubber to dig a shallow small round hole 2 to remove the brush pen head, clean and dry.3 cut the tip of the brush head into a small brush4 put the brush head into the small hole in the rubber, glue (complete)2 small production: solar hot water bag
Q:Solar electric vehicle charging device
Electric vehicle using solar silicon and polysilicon combination surface for Ling lighting plate, high quality and high efficiency crystalline silicon plate, the weak light response is very good, high photoelectric conversion efficiency, both indoor and outdoor sunlight, can be 24 hours of uninterrupted charging for electric vehicles to absorb light, can meet the different electric vehicles with electric load.
Q:30MW solar thermal power plant total investment
At present, there are three kinds of solar cells, such as monocrystalline silicon, polycrystalline silicon and amorphous silicon. Monocrystalline silicon solar cell conversion efficiency of up to 20%, but the price
Q:Is there any water in the solar energy to water?
In the case of water inside the solar energy can also be irrigated 1,
