The solar vacuum tube has a good heating effect
- Compared with the use of hair dryer, the safety of this approach is much higher, as long as the water is not large enough to move the body.s
After wafer cleaning, how to change the film?

What should I know about the Crystalline silicon photovoltaic cells?
- Crystalline silicon photovoltaic cells is the most early development of a solar cell. 1.leV, the band gap width of silicon, is an indirect migration type semiconductor, which is not the most suitable material for making solar cells.s
I am working on research for the usage of solar cells, where can I find more news of solar cells?
- If you are looking for the most up-to-date news about the solar cells, you should visit Sciencedaily for more information.s
Polycrystalline solar panels are good or single crystal solar energy is good
- Polycrystalline silicon solar cell production process and monocrystalline silicon solar cell almost, but the polysilicon solar cell photoelectric conversion efficiency will have to reduce a lot of its photoelectric conversion efficiency of about 12% (s
45 Watt Solar Panel -?
- Lets say, for a simple approximation, that the 45 watt panel produces 45 watts /3 of the time and nothing the rest of the time. Each day, this will produce 8 hours times 45 watts = 360 watt hours. Also assume the battery charge controller and inverter waste half of that power, leaving 80 watt hours per day. If you use compact fluorescent lamps, that would allow you to burn 80 watts worth for an hour every day, or 90 watts for 2 hours, etc. That is a lot of light for a shed. You might consider using much less efficient tungsten filament lamps, but eliminate the inverter and choose low voltage (automotive) lamps that can run directly across the battery and lower the total cost, but give you only about half the light times time. The main advantage of the inverter might be that it would allow you to use small power tools or appliances in the shed. -- Regards, John Popelishs
Are solar panels actually efficient?
- Solar panels currently hook into the electric grid through a rectifier. If you were not into the grid, you would have a battery bank to use at night time. Wind works the same way, rectifier, and battery bank if you are not connected. There are communities in Europe that are wholly powered by solar now. There are computers that direct the panels into the direct sunlight for maximum efficiency. Look for them to be coming to your neighborhood soon.s
