Q:Solar garden lamp product parameters: * main body material: the lamp post is full steel structure, whole hot galvanizing / plastic spray treatment* solar modules: crystalline silicon 15-80WP (by load configuration)* operating voltage: DC 12V - 24V* controller: solar lamp controller, light control + time control

Q:How to open solar stores: There is a solar dealer, in the local solar market, can be described as a coup. Use the bus as a propaganda tool, bus station, the first sentence is: "a certain store solar power station to remind you:" in the caption on the bus, he hit the store's telephone and communication; on the phone 114, the opening of the new building signs, banners, and even background cloth Online shopping, playing a certain solar energy store. In view of the store is more than the target customers, the dealer also sent a trick to go back and forth to its store expenses reimbursement, in this way, the customer into the store. With the help of external forces, a good manufacturer of this card. Dealers in the choice to join an industry, have to go through thousands of pick million, so that the industry has the impact of brand agents.

Q:Monocrystalline silicon market when the turnaround, to what extent: China's solar photovoltaic industry is not a bright prospect of solar photovoltaic industry competition and traditional fossil energy competition. As a result of fossil fuel causes global warming, the world is looking for new alternative energy program, the EU put forward in 2020, the substitution of renewable energy to reach 20%, 2050 reached 80% - 100% plan, Chinese also proposed in 2020 reached 15% China the proportion of non fossil energy, so in the future alternative energy plays a leading energy what is energy?

Q:What is the difference between photovoltaic products and solar energy?: At the same time, the solar photovoltaic power generation system, which is centralized, such as large northwest ground photovoltaic power system; one is distributed (divided by >6MW), such as building roof photovoltaic power generation system of industrial and commercial enterprises, residential roof photovoltaic power generation system.Solar photovoltaic effect, referred to as photovoltaic (PV), also known as the photovoltaic effect (Photovoltaic), refers to the uneven illumination of semiconductor or semiconductor and metal parts of the potential difference between the phenomenon of.Photovoltaic is defined as the direct conversion of ray energy. In the practical application, it usually refers to the conversion of solar energy to electric energy. Its implementation is mainly through the use of silicon and other semiconductor materials made of solar panels, the use of light to generate direct current, such as our daily lives can be seen everywhere in the solar cell.

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:How to choose a good use of solar energy: See building structureMulti story building: installation is not limited, vacuum tube solar energy and flat panel solar energy products can be selected. Senior and small high-level: balcony solar energy products can choose. Villa Construction: can choose to install flexible, can be integrated with the construction of flat panel solar energy, flat panel solar energy is not affected by high-rise and special buildings, beautiful and generous.See pipeBecause the water heater is often placed on the roof, there is a certain pressure and the house in the summer, hot water with high temperature (about 90 DEG C), the actual situation of low ambient temperature, so the best selection of crosslinking tube or plastic composite pipe or reinforced plastic hose. The utility model has the advantages of high pressure resistance, high temperature resistance, low temperature resistance, no toxicity, no odor, small heat capacity, small heat loss, and easy to freeze in winter.After-sale serviceThe best choice of well-known brands and the strength of dealers (longer distribution time, product quality complaints rate) of the water heater. Because the solar water heater is durable consumer goods, and usually installed in the roof, once the fault, it is difficult to deal with their own. So the customer service service must be guaranteed, at present, the whole market free warranty period of 3 - 5 years.

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:In the domestic high temperature solar energy collector can achieve how many degrees, the existing product and the technology form?: The tower system, Zhongxingpengyue pattern, looks very spectacular, is the image project of solar thermal power generation love. Its size is limited to 10~20 megawatt level, the use of special, very limited usefulness. The tower system operating temperature 600~1000 degrees Celsius, there are several foreign demonstration projects, the home also has heard, but I do not know the specific progress to that stage, both at home and abroad have not heard of commercial operation successfully.Dish type system, the operating temperature of 700~1400 degrees Celsius, stand-alone dozens of kilowatts, the system 5~25 mw. Due to the small machine, a large number of prototypes developed at home and abroad, but also did not hear of a successful large-scale commercial operation example. Due to the use of Stryn hot gas engine, its manufacturing technology requirements are high, greatly limiting its development.

Q:Good solar polymer or monocrystalline: Working principle: the light of the sun to the solar battery plate current generated through the inverter controller for battery charging, battery power through the inverter controller into DC or AC electric power supply (load), or through the grid connected inverter of direct energy input power grid. Solar photovoltaic system consists of solar cells, solar controller, battery (Group), such as the output power for AC 220V or 110V also need to configure the inverter. In the specific design of system engineering, the following factors should be considered:

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: 1 natural circulation:This type of storage tank is placed above the collector. Water heating collector in solar radiation temperature rise, causing the collector and tank water temperature and have a different density difference, thus causing buoyancy, this is like a hot siphon, the water flow in the water storage tank and collector. Because of the density difference, the water flow rate is proportional to the solar energy absorbed by the collector. This kind of type is widely used because it does not need the circulating water and the maintenance is very simple.2 forced circulation:The water in the hot water system makes the water circulate between the collector and the water storage tank. When the water temperature at the top of the collector is higher than the water temperature of the bottom of the water storage tank, the control device can start the water to make the water flow. A check valve is arranged at the entrance of the water to prevent the nighttime water from being driven by the collector to cause heat loss. The flow rate of this type of hot water system can be known (as a result of the flow from the water), easy to predict performance, can also be calculated in a number of hours of heating water. As in the same design condition, the natural circulation has can gain higher water temperature strengths, but because it must use water, the water power and maintenance (such as Water Leakage etc.) and the control device of dynamic stop, damage easily water problems. Therefore, in addition to large hot water system or the need for a higher water temperature, the forced circulation, the general use of natural circulation water heater. Solar power system consists of solar cells, solar controller, battery (group). Such as output power for AC 220V or
