FAQ

New solar productsI would like to know the new type of solar energy production enterprises and the name, product performance and parameters.

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.

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

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

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

Household solar energy productsThe product can be used at home, do not mention the solar energy, answer the water heater

Solar thermal products are solar water heaters, as well as solar heating systems (usually in the North). Solar water heaters are used in several sets of hot plate, the more common is flat solar and vacuum tube solar two, the former used more in the south, the latter used more in the north.

Solar energy product development prospects?

2012-2016 China solar cell market analysis and Investment Research Report1 solar water heater industry faces new integration. Industry concentration is not high, at present the country's top ten brands of solar companies together market share is less than the national market of 10%, companies want to get a larger market share is difficult. A line of enterprise and brand most high-end centralized development mode, to keep the solar intelligent and widely used will be closer, the solar water heater into the application of high-end, intelligent, integrated, brand enterprises lead the development direction of the industry's highest level and lead the industry, sales of high-end products less.

What are the third generation solar cells

In 2004, Professor Green proposed the idea of developing the third generation solar cells. If we apply the semiconductor crystal film solar cell is called the first generation of solar cells, thin film solar cell is called the second generation solar cell, then the third generation solar cell solar cells the next generation is expected

Good solar polymer or monocrystalline

Many of my friends would ask is good or good crystal crystal, we many people buy just as ordinary lighting and small system to watch TV, to tell the truth this is really no need to care about the single crystal or polycrystalline, regardless of the need is a power is enough, two is the price is good!The difference between polycrystalline and single crystal: single crystal plate is black, polycrystalline plate is blue or color.Disadvantages: the same power of the single crystal plate with polycrystalline plate, polycrystalline board area slightly larger than the area of single crystal board, the same as the 50W polycrystalline will be 1.1 times larger than the single crystalThe utility model has the advantages that the polycrystalline plate is a plurality of directions to receive light and has good directivity. The actual test, hypothesis with one hand to block the sun's rays to solar power on the surface of a shadow, so many crystal board power current decrease is not obvious, but the single plate power current is reduced obviously, this is the advantage of multi crystal plate.

Solar heating easy to use? Has anyone used it

If your house has a little heat preservation effect, the heat collector area is not enough. The first is fraud, very high! Followed by the heat collector is often no place to swing! Again, so many collectors, the heat generated in the summer there is also a problem
