Is there any water in the solar energy to water?
- How much is the automatic water supply set level up to the number 2 can not need to fill 100 set automatic water temperature time to remove any fills
The advantages and disadvantages of solar energy?Want to buy solar energy solar energy what is bad? Know about
- 3, placed the location of stress, angle, sunlight time, the surrounding environment is not easy to miscellaneous. Although the outside component is made of toughened glass, but also can not afford to toss the firecrackers. And aroundIf there is debris, easy to cause the "island effect" causes the component to burn oh.s
How about the effect of wall hanging solar energy
- Wall type solar water heater can belong to the separated type solar hot water system, water tank placed in the balcony or exterior wall, the collector is placed at the south facade of building a balcony wall hanging type solar water heater with flat collector to absorb solar radiation into heat, heat to reach the water tank and the water heat exchanger, so that the temperature of the whole the water tank is increased gradually, let the user can enjoy free hot water from the sun.The successful use of plate heat exchanger technology in wall mounted solar products, not only improves the thermal efficiency of balcony wall products, and the successful implementation of the building safety products and life integration, so that the water heater installation expanded to all floors and is not limited to the roof, and greatly lifted the traditional solar water heater, frozen fried tube, easy Water Leakage, easy scaling problems.s
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.s
What are the uses of solar energy?
- Uses as follows:Photothermal utilizationIts basic principle is to collect the solar radiation energy, and convert it into heat energy. At present, the most widely used solar collector, there are 4 types of flat plate collector, vacuum tube collector, ceramic solar collector and focus collector (trough, dish and tower). Usually according to the temperature and the use of the different, and the use of solar thermal light is divided into low temperature (<200 DEG C), the use of medium temperature (200 ~ 800 C) and high temperature utilization (>800 C). At low temperature using mainly solar water heater, solar dryer, solar distiller, solar heating (solar room), solar greenhouse, solar air conditioning system, the temperature is mainly using solar cookers, solar thermal power generation heat collecting device, mainly using high temperature high temperature solar furnace etc..s

Solar energy product development prospects?
- 2 domestic solar water heater market development problems, intense competition. 2010 in the first half, the solar water heater industry ushered in the most severe market test, the number of manufacturers dropped from last year's more than 5 thousand to the current more than 2 thousand and 800. There are relevant data show that nearly 80% of the solar water heater companies have varying degrees of decline in sales, inventory increases and other issues, solar water heater industry's profits are getting lower and lower. In nearly 6000 domestic solar water heater business, really have the scale of production and R & D capabilities of enterprises less than 20, the rest for some local small workshops and brand-name enterprises. However, the quality of product inspection management, backward production technology, low price dumping, Jerry phenomenon in these small enterprises, resulting in solar water heater market order and chaos, there are many hidden dangers.s
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.s
