Q: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.
Q: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.
Q:What are the references of the solar automatic tracking system
This paper studied the sun automatic tracking of the independent photovoltaic power generation system based on solar photovoltaic power generation as an important way of utilization of solar energy, the development prospects are very broad. At present, the photovoltaic power generation system with fixed form, the power system has the disadvantages of low power efficiency, high cost and difficult to promote.
Q: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.
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
Q:What about solar products?Solar panels solar panels
Solar photovoltaic products: photovoltaic modules and photovoltaic components, modules and components of rural production equipment, photovoltaic power generation system, photovoltaic equipment installation and accessories, grid connected photovoltaic system and photovoltaic transmission and distribution equipment; photovoltaic power / battery, charger, controller, inverter, water pump, solar power system equipment, solar energy conversion equipment, fuel cell, silicon solar cell, thin film solar cells, silicon single crystal silicon cell / raw materials, photovoltaic panels, glass cutting machine, testing equipment, various kinds of stove; wind solar diesel battery hybrid power systems, solar desalination system, solar photovoltaic electric vehicles, hydrogen production system, photovoltaic power generation system of computer application software; testing equipment of photovoltaic power generation system.
Q:Solar electric vehicle charging device
Performance characteristics of solar charger for electric vehicle:1 suitable for 36V, 48V configuration of the electric vehicle voltage conversion2 unique electric vehicle battery repair function, because of its continuous battery to supply electric power to prevent and remove the battery plate sulfide, recovery of battery capacity, prolong battery life, reduce the economic burden of the users.3 using the level of intelligent tracking system, the use of a new track concept, to achieve a day in the system of the sun's automatic tracking, improve the photoelectric conversion rate, increase the power supply to the battery.4 unique overvoltage protection technology to ensure the safety of charging equipment.
Q:Are solar panels now in use?
Servo drive, also known as "servo controller" and "servo amplifier", is used to control the servo motor
Q:Solar panels can be charged directly to mobile phones and other products
Solar panels can not be used directly to charge mobile phones and other products. The output voltage of the charger for mobile phone and other products at around 5V, and the output voltage of the solar panel is not fixed, fluctuated, when more than 5.5V or higher, causing permanent damage to products such as mobile phone, must control the output voltage between 4.5 ~ 5.5V through the conversion circuit.Built in battery is in order to output more stable, but the premise must be configured safe and effective protection circuit and voltage conversion circuit.
Q:Solar products must be in the sun
Solar energy products are generally inseparable from the sun, but there are also some of the solar radiation energy demand for smaller products
