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:PV solar products market sales

According to the State Administration of taxation policy released last year, from October 1, 2013 to December 2015 3l, according to the 3% levy rate calculation. In Takamatsu as an example, if a month sales of 30 thousand, that he should pay the tax is 30 thousand x 3% x 50%=450 yuan.Residents issued 1 kwh of electricity, the state subsidy of 0.42 yuan; the national standard for the purchase of electricity from the desulfurization of residents with endless self generating electricity, the price is $0.42 per degree. To install and use a set of distributed photovoltaic power generation system with an average of 1 kilowatts of installed cost about 10 thousand yuan, if the 8 kilowatt system daily generating capacity of 30 degrees, 5 degrees every household consumption (no more than a price of 0.52 yuan), about 8 years to recover the investment

Q:Now there is no sun, cloudy days can use solar products?

At present, I have not found this kind of solar energy

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:Or must there be built - in battery? If yes, then use the mobile phone lithium battery can?

Solar panels can not be used directly to charge mobile phones and other products. The output voltage of the charger for mobile phone and other products at around 5V, and the output voltage of the solar panel is not fixed, fluctuated, when more than 5.5V or higher, causing permanent damage to products such as mobile phone, must control the output voltage between 4.5 ~ 5.5V through the conversion circuit.Built in battery is in order to output more stable, but the premise must be configured safe and effective protection circuit and voltage conversion circuit.

Q:How to make better use of solar energy

The first stage (1900~1920 years) at this stage, is still the focus of solar power plant solar energy research in the world, but the spotlight by diversification, and began to use the flat plate collector and low boiling point device, gradually expanded, the maximum output power of 73.64kW, with the objective clear, cost is still high.

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:What are the current domestic solar energy products, which practical

Photovoltaic power generation system is mainly composed of solar cells, batteries, controller and inverter, the main part of solar cells. In the application of more public amenities such as solar street, home of the little, of course you can install the system of solar photovoltaic panels at home, 1W about ten dollars, plus the controller, you can see if you are able to supply applications at home how much money.

Q:Solar energy application technology, there is no prospect

At present the solar energy situation is not optimistic, the Americas and Europe has Chinese solar "double reverse" and China internal and not good, can not be the own production of solar energy products consumed, resulting in pile up in excess of requirement. Therefore, many Chinese solar manufacturers have closed down.

Q:Solar heating easy to use? Has anyone used it

Advice do not believe! Solar heating is just a concept in china. In theory, in northern China, walls, windows and doors insulation to do a very good case, a square meter of solar collectors up to 3 square meters of heating area. If your house is 90 square meters, according to this calculation, you need to have 30 square meters of solar collector area
