About PV Ribbon:

PV ribbon is composed of Copper and coating alloys, and divided into Tabbing Ribbon and Bus bar ribbon.
•Tabbing Ribbon: it is commonly connects the positive and negative sides of the cells in series.
•Bus bar Ribbon: it is concentrate the cell stringing into junction box and channels electrical curren

Q:Solar water heater for a long time how to deal with?
If the home to buy solar energy, temporarily do not have to use it, it is recommended that you use blankets, carpets or quilts cover the vacuum tube to avoid the sun, so there will be no problem.
Q:Water storage capacity of solar water heater
To determine the day with hot water, the total amount of P (kg) P (kg), F (kg) /m2, to obtain the solar collector area of S (M2), per square meter of solar collector with 0.1m3 thermal water tank capacity ratio can be calculated, the heat preservation water tank capacity: V=S (M2) *0.1m3/m2.
Q:The working principle of solar cells includes the three processes
In the solar cell pn junction on both sides of the lead-out electrode, and connected to the load, then in the external circuit that is generated by the photogenerated current to obtain power output, so that solar cells put solar (or other light) directly into electrical energy
Q:What can be used to adjust its viscosity
Polyethylene glycol and water soluble, I believe this may help you solve the problem
Q:Do you have a solar charger?
What should I pay attention to when using solar mobile power? First of all, pay attention to the strong light to the mobile power when charging, please do not interval, at least charge 8 hours, the battery can be filled. We all know that more than eight hours a day without direct sunlight is still a bit difficult.
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:Construction of an area of 1000 square meters of solar power, about how much investment
Tile, that is, the component tilt 0 degrees, the assembly into a row layout. Calculation to consider the maintenance of the channel, the general arrangement of 1 meters between each row of the maintenance of the channel, the duty cycle is 1.5-1, the actual component area of 1000*1.5/ (1.5+1) =600m2. According to the calculation of crystalline silicon module 150W/m2, power generation is 90kW.
Q:Installation of vacuum tube sealing ring for solar water heater
The whole hand feels smoother and doesn't move! If you can, so that the other can be installed under the demonstration of the master ah!
Q:Mineral resources and forest resources, which is renewable resources and why?
Because, under certain conditions, it has the mechanism of self renewal and self reproduction. It includes the regeneration of forest resources and the regeneration of various resources
Q:1 megawatts of solar energy need how many wafers
It depends on whether it is a single crystal or polycrystalline, I only know that polycrystalline is about 3.8 mw.
