Q:How to remove the solar water heater tube
The first time you remove the best choice is cloudy, morning or evening, because you must first put hot water in the solar water heater all let go before the demolition, demolition was oozing to avoid scalding hot water, if the demolition is at noon, because the vacuum pipe of the water has been drained, and then by the strong sunlight will loss and vacuum tube, vacuum tube will shorten the life of.3, after the demolition of vacuum tube to use special polyester foam grid installed, put in a special box, lest accident in handling collision. Because this step is the most difficult, the most dangerous for non professional people, a vacuum tube can be completed after the demolition.
Q:How many solar panels do we need to power the US?
Annual power consumption in the US is approximately .2*0^5 Watt-hours. The average solar panel can generate 80W continuously. We can break up the calculation into parts: .2*0^5 Watt-hours per year 925 hours per year .3*0^ continuous watts 80W per panel 64383566 panels 000 sq. inches average solar panel area 650 million square miles (!!!) To give you a better idea, the total surfacre area of the United States of America is 3 million square miles. The surface of the earth is 96 million square miles. Not even 3 planets full of solar panels would be enough. Maybe it is easier for people to start using electricity more responsibly?
Q:What is the meaning of a cleaning in a semiconductor silicon wafer process? RCA?
() APM (SC-1): NH4OH/H2O2 /H2O 30 ~ 80 DEG C due to the action of H2O2, the surface of the silicon wafer has a natural oxide film (SiO2), which is hydrophilic, and the surface of the silicon wafer can be soaked with the cleaning liquid. Because the natural oxide layer on the surface of silicon wafer and the Si on the surface of silicon wafer are corroded by NH 4OH, the particles attached to the surface of the silicon wafer will fall into the cleaning liquid, so as to achieve the purpose of removing particles. At the same time, the H2O 2 forms a new oxide film on the surface of the oxidized silicon wafer when the NH4OH is etched on the surface of the silicon wafer.
Q:Solar silicon wafer cutting fluid can burn explosion?
2, the glass can not be used as the bearing plate of the crystal rod, if the use of graphite plate, grinding down the silicon powder containing a certain amount of graphite, it is difficult to deal with the recovery of silica fume3, can only be used for single crystal cutting4, the cost of the problem, and now the price of diamond wire fell faster, diamond wire cutting costs should be close to the cost of cutting free abrasive
Q:Are solar panels actually efficient?
It absolutly depends on where you live. I don't have enough wind in my area for a wind turbine to do any good. I just installed solar, the system will pay for itself in about 6 years. I didn't get a system that will zero out my electcity usage, but it will dramatically be decreased. I can always add to it in a few years. Since I plan on living here forever I will see a great financial benift.
Q:can I easily build my own solar panels for my home?
It's okorder.com/ has something to say about various scams, including solar.
Q:What is the use of silicon?
Affected by the rapid growth of demand for solar energy, the production of silicon raw material polysilicon prices a few years up to 3 times, and is expected in the next few years, polysilicon supply gap will be maintained at around 5000 tons, the price of polysilicon is expected to continue to rise. This will likely lead to a new round of China's silicon chip industry reshuffle, looking for international technology partners will be one of the ways.Photovoltaic industry to promote polysilicon prices skyrocketingPhotovoltaic industry is becoming the hottest new energy industry, the United States listed Wuxi Suntech chairman Shi Zhengrong thus became one of the richest people in china. But the vigorous development of solar cells also led to rising prices of polysilicon raw materials, and hit the domestic semiconductor materials industry.
Q:do solar panels have to be in direct sunlight?
PV panels do not have to be in direct sunlight. If they are behind glass they need to be well ventilated to remove excess heat. If PV cells connected in series are not uniformly illuminated the series will produce an amount of power that is based on the light on the least illuminated cell. Thus moving a panel back from a window will mean that for large parts of the day it will produce almost no power as parts of the panel are shaded. This applies only when the cells are connected in series. In parallel they suffer no special degradation of production, but just the sum of illuminated cells. This makes a difference when you decide to use a higher voltage panel... high voltage panels are more susceptible to partial shading. But connecting low voltage panels in series gives that same degradation. Stay away from placing a panel back away from the window, or close to the edges of the window, under roof overhangs, trees and surrounding building shade, where possible.
Q:What are the advantages and disadvantages of solar water heater?
In the summer of 4, sunny weather conditions, less than two days water temperature can reach the boiling point, if a long time without water, such as travel, tourism, to make the water a long time at high temperature and high pressure condition, will accelerate the aging of the sealing ring, accelerated aging, polyurethane shrink, sometimes the exhaust is not smooth, too much pressure the water tank will swell bad, will shorten the life of furring, water tank. Therefore, if you are not at home for a long time, you should arrange for others to put hot water on the cold water, or put a cover on the vacuum tube collector to block the sun.
Q:Solar vacuum tube water or water is good
Each has advantages and disadvantages, is generally not used in water or poor quality of a cold winter in the north, South to choose water type, water does not work in the original is by vacuum, a long time, the vacuum tube is reduced, the heat collecting effect will be greatly reduced, the water is frozen fried tube the possibility of pipe, but the service life is longer than that without water, especially after 35 years of use, the effect will be significantly more out.
