Q:PV solar products market sales

The state has introduced the relevant subsidy policy, fairly good prospects.Solar power generating capacity per square meter is about 120W, the cost per square meter 1500 yuan in the area, the greater the lower the price of 2013 the PV industry has been an antitrust investigation in Europe, because of overcapacity in Zhejiang's large solar photovoltaic industry collapse, the price fell down. This can always online inspection recommended the purchase price of solar water heaters each priced at 150-180 yuan according to material, and other costs, the purchase is optimistic about the local power and reliable customer service of solar panels, the size of the group suggested bidding, mainly electric power and storage equipment is very expensive, the highest conversion rate in 17%-20% efficiency is very low now, as the plant photosynthesis national clean energy, photovoltaic power generation policy is more than 10kW can free grid, but the recovery price is very low, cumbersome.

Q:How to promote the use of solar energy in China

Can you be more specific? Because I'm working on a project report, it's best to talk about two aspects of government and solar energy companies

Q:How to choose a good use of solar energy

See brandAt present, there are more than 5 thousand brands of solar water heater industry, of which, a small family workshop type enterprises accounted for the majority of such enterprises weak competitiveness, the average life expectancy of enterprises, but only 1.5 years. Consumers choose products produced by such enterprises, often a few years later will become a three noes products, the interests of consumers can not be guaranteed. Therefore, consumers should choose in the country's high visibility of the big brands, big brands of solar water heaters not only reliable product quality, but also to provide consumers with long-term after-sales service protection.

Q:Product category and comparison of solar thermal utilization

What is the reason?The main reason is that China's solar energy (water heater) is the most in-line vacuum tube solar water heater, vacuum tube itself is vulnerable, tube explosion caused by vibrations, icing, improper water and other reasons, the vacuum tube fouling phenomenon is very serious, affecting the normal use, needs a great amount of customer service service, high maintenance costs. Once, encountered bad weather, frequent accidents, too busy to attend to all enterprises and dealers.Where is the way out?According to the experience and lessons of foreign countries, the use of a new type of high-performance flat solar energy is the most feasible and effective solution.

Q:Is it hot in summer and the water is hot in winter?

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.

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

Mobile phone battery as an energy reserve, but no 5V output boost function, the same can not charge the phone. If you have bought a solar panel, you can buy a mobile power with the use of

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

Our use of solar energy can be roughly divided into two types of light and heat conversion and photoelectric conversion, in terms of household solar water heater and solar photovoltaic power generation.The solar water heater is widely used, manufacturers have Wuxi Suntech, linuoruite, Himin Solar energy, I think the emperor of the more, certainly not bad.

Q:Solar derived products The role of solar panels is to convert solar energy into electrical energy, the output of DC stored in the battery

On the direct use of solar energy in humans is still at the primary stage, mainly solar collectors, solar water heating systems, solar heating, solar power, solar wireless monitoring etc.. Along with the development of modern enterprise system in our country's popularization and deepening development of enterprise informatization construction unceasingly thorough, safety and prevention work for enterprises using digital video technology has been combined with the development of solar energy technology represent the general trend, the launch of the real Winncam zero wiring for wireless monitoring solution. (solar wireless monitoring installation renderings)In the modern industrial park, the implementation of video surveillance system, the security department can realize all-weather real-time video monitoring in the industrial park at the entrance, the main road, office buildings, such as perimeter wall sites; the relevant departments can understand the situation, strengthen campus security management, improve work efficiency; the relevant departments can real-time understanding of each monitoring point the leading enterprises in the office; using a desktop computer, you can keep abreast of the real-time status of each monitoring point, handling emergencies, can also record multiple days ago, tracking and analysis, in addition to the establishment of local network monitoring system, but also to focus on remote video monitoring of branches. The actual production of Zhongcheng labor discipline inspection at any time Trw Corporation employees according to the actual needs of the park, some difficulties to take power, we use Solar power supply, with reference to the relevant international standards and national standards, combined with the company's experience in the Industrial Park monitoring and accumulated, the preparation of this zero wiring solar wireless monitoring technology program.

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

Solar energy can be combined with heating. But it is still defined as "energy saving" more appropriate, rather than defined as "heating". The use of solar energy must be energy efficient. Suggest you can use gas stove heating, more money. If you want to save energy, then the gas stove and solar energy, solar bath, gas stove for heating and auxiliary heating as a solar energy.

Q:Is there any water in the solar energy to water?

Yes, but it's best not to add water during the day
