What is the future of solar power
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. In accordance with the same calculation method, 10 kilowatts of distributed photovoltaic power generation device to recover the cost of 9-10 years. Family photovoltaic power plant to recover the cost of an average of between 8-10 years.
Advantages and functions of solar energy
The advantages of solar energy: solar energy as a new energy, compared with conventional energy it has three major characteristics: first, it is the most abundant energy source. It is estimated that in the past 1 billion 100 million years, the sun itself consumes energy in the future 2%. is sufficient to supply earth, using billions of years it is inexhaustible, inexhaustible.
New solar productsI would like to know the new type of solar energy production enterprises and the name, product performance and parameters.
Solar automatic drip irrigation systemThe day before, Xinjiang production and Construction Corps three group introduced from Australia two solar automatic irrigation system, used for the first time in china.According to reports, this system is mainly composed of solar panels, automatic controller, water pump, filter, fertilizer tank, field network composed of several parts, it is the biggest characteristic of the photoelectric conversion of DC is generated by solar panel, direct drive pump automatically for the implementation of field crop irrigation, three solar panel configuration, total light area of 3.84 square meters, can produce a voltage of 132 volts, the power of 540W, the amount of water per hour is 2200 liters, 30 acres of drip irrigation can meet the needs; at the same time according to the optical conditions, the system can automatically open and close, the winter slack season, the system can also install conversion equipment, to meet the electricity needs of workers living.
Solar energy application technology, there is no prospect
I'm making solar energySimply put: solar energy is a new type of energy, the most important feature is pollution-free and inexhaustible. Therefore, under the condition of large amount of conventional energy consumption and environmental pollution, new energy has become a trend.
What are the disadvantages of traditional solar water heater
As a developing product, solar water heater is not perfect. People are skeptical about solar water heaters, solar water heaters can normal water supply, can bring convenience to life?
Solar energy items in daily life
Solar water heater, charging treasure, rotating wheel, battery board Solar cell / solar engine
PV solar products market sales
The roof of photovoltaic power generation is less than 2 million monthly sales tax, in accordance with the provisions of the national taxation policy, power users need to provide sales invoices to the power supply enterprise, the buyer also need invoice offset the cost, and the personal power does not have the qualification of business owners, led by invoices complicated procedures. More than 20 thousand of the tax can not get the invoice, it increases the difficulty of the sales of power generation households, is not conducive to promotion. The State Administration of Taxation issued, will reduce the tax burden on household electricity."According to the State Administration of taxation documents, since July 1, 2014, the national Power Grid Corp to buy power products distributed photovoltaic power generation project, by the national Power Grid Corp invoices, monthly household electricity generating sales of more than 20 thousand products, owned by the national grid enterprises in accordance with the taxable amount of the 50% generation of vat. The monthly sales of less than 20 thousand yuan may be exempt from vat.
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.
