Q:What is the difference between the expensive solar energy and the cheap one?

Some solar energy is more expensive than other products! But is it worth it?! We do not have a word called a penny a point goods, product quality and price are proportional to

Q:The advantages and disadvantages of solar energy?Want to buy solar energy solar energy what is bad? Know about

You mean the solar water heaterSimply say:Benefits: power saving, safety,Disadvantages: 1, temperature affected by the weather,Because solar water heaters rely mainly on the absorption of sunlight, the light energy into electricity for heating waterSo the intensity of the sun directly affects whether you need to use electricity heating

Q:What are the functions of the new vehicle negative ion solar charging humidifier?

Brown vehicle negative ion solar charging humidifier, in addition to negative ions and solar charging function, but also can be used as car fragrance, you can add essential oils.

Q:Product category and comparison of solar thermal utilization

The solar industry did a survey on the overall evaluation of the use of solar energy users, think very satisfied with only 3.5% basic satisfaction was 12.6%, average and unsatisfactory accounted for 35.2% and 48.7%; the user evaluation of the service, satisfied and satisfied for a total of 24%, and that no service dissatisfaction accounted for 76%.

Q:For example, solar flashlight, solar watches and other small solar products are what? Shenzhen where can be approved...

Solar water lamp power supply, inverter solar watch packaging glass packaging film melted material monitoring system wiring box of solar wind cap regulator controller

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:Solar energy products, that is, I would like to open a home solar products Daquan

Photoelectric, two large blocks of light and heat, I think it will be a complete. But a lot of financial strength to do it

Q:30MW solar thermal power plant total investment

At present, there are three kinds of solar cells, such as monocrystalline silicon, polycrystalline silicon and amorphous silicon. Monocrystalline silicon solar cell conversion efficiency of up to 20%, but the price

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:The steps of making solar technology stubs

Material Science：Black plastic bag, rope.Making method:The black plastic bag filled with water after the bag tied in sunlight (see photo). After a while, the bag of water on the heat, can be used to wash your face, wash your feet.3 material: walnut, stick, rubber mud, small cloth.
