thermodynamic question that includes heating water with solar panels?

Solar water heater in winter should pay attention to what?
- 3, pipeline antifreeze and insulation is the keyPipe antifreeze solar water heater needs extra attention, especially the water tank and the water pipe junction, this time the local wind and water easy to shake, if the connection is not good water easily exposed, cold to freezing, causing cold water to hot water down phenomenon, so thermal insulation hose must to do a good job, a general insulation pipe length is two meters, each heat pipe connection to tape fastened to prevent disconnection when the wind or water.s
Solar Panel: Watts, Amps, Volts? mA?
- . 3V 200mA. mA (milliAmp) = 0.00A; Power = 3V x 0.2A = 0.6 Watts. 2. 6V 00mA is 6 x 0. = 0.6 Watts. 3. 9V 50mA is 9 x 0.05 = 0.45 Watts. 4. 2V 50mA is 2 x 0.05 = 0.6 Watts. With the 3 Volts one you could connect it to a flashlight light bulb, that's is about the max you can get out of it. With the light bulb, polarity doesn't matter, but if you power a small transistor radio with it, then make sure the + goes to the + and the - to the -. Reversing it wouldn't work and in some cases you could damage equipment.s
How to generate solar cells, the principle of PN junction
- Salt, such as gallium arsenide III-V compounds, cadmium sulfide, copper indium selenium and other multi-compound materials for the battery; 3, functional polymer materials prepared by the large solar cells; 4, nano-crystal solar cells.s
Process flow of wafer wafer ultrasonic cleaning machine?
- Plasma cleaning method, which is characterized in that the process parameters of gas flushing process is: the chamber pressure of 15 mTorr, process gas flow 300sccm, time 3S; process parameters of starting process is: the chamber pressure of 15 mTorr, process gas flow on the electrode 300sccm, power 300W, time Sss
What is a silicon wafer for unidirectional and bidirectional cutting? What is the difference between the two?
- One way and two way cutting of silicon wafer is the two way to cut silicon ingot by using solar energy cutting wire.When slicing machine uses solar cutting line to cut silicon ingot,s
When you get solar panels do you connect them to the grid?
- Not directly and it also depend on where you live. If where you live has net metering then they would be indirectly connected to the grid, there is equipment involved besides just the panels on the roof.s
How effective are solar panels now in N E with our 40+ snowfall this month?
- Just okorder.com/... As an aside the efficiency of the panels will also be maintained if the panels are cleaned of dust and debris. The maintenance of removing snow and dust is one argument for having the panels on a rack on the ground. Solar Thermal panels are intended to capture the sun's heat. Two types that make hot water are flat panels and vacuum tube collectors. The vacuum tube collectors work better in colder and cloudy areas but their efficiency prevents heat loss that might melt snow. Most of a light snow will fall between them but you are back to maintenance with a heavier snow. Flat panels are less efficient and will melt a light snow off of the panels for a heavier snow you will need the roof rake. The last type of solar panel are solar air panels. These are most often mounted on the side of a house rather than the roof as they are intended to provide hot air to the living spaces. They are essentially like little greenhouses. Unless the snow is building up against the side of the house these should be free from a snow problem.s
