Q:I have a 6v solar panel , but a 3v dc motor doesn't run with that!!!!?
It may well be that the motor demands more *current* than the panel can provide. Can you measure the voltage from the panel with the LEDs across it, and then with the motor across it? I suspect that you'll find that the motor makes the voltage collapse.
Q:can a light bulb power a solar panel?
Solar Powered Light Bulbs
Q:Solar panel wiring trouble.?
You are probably wiring them incorrectly: with the positive on panel A connected to negative on panel B; and the negative on panel A connected to the positive on panel B. If you want then connected in parallel, connect the positive on panel A to the positive on panel B and the negative on panel A connected to the negative on panel B. But you will only get vdc. You can't get .5 volts from two volt sources. You can get 2 volts by connecting the panels in series.
Q:how long do roof solar panels last?
All okorder.com/... PV warranties typically allow for 20 percent output degradation over the module’s 20- to 25-year warranty life. But measurements of many modules put into service in the 980s show that it’s unusual to see even half that much degradation. Many of those earliest modules still perform to their original specifications. It is safe to say that modules carrying warranties of 20 years or more have a high probability of working well 30 years from now
Q:Why are solar panels only 0% efficient?
Unlikely that we gan get to near 00% efficiency, although there is room for improvement. In the meantime, don't pooh-pooh 0% efficiency. That's about the rate of energy transfer up a food pyramid, perhaps a little less at the solar to plant level. As this manages to provide the basis for most of life on earth, it's nothing to sneeze at. As far as the other 90% goes, I would guess that much of it is reflected.
Q:solar panels for your home?
Hello, Yes you definitely can use this kind of panels. Powering your home entirely will be an issue if you are not familiar with solar energy and electricity in general. If it's the case I'm afraid you'll need a specialist. The basic principle of a solar power system: - Solar panel to charge the batteries - DC to AC converter that will convert the DC voltage from your battery to AC voltage so that you can connect regular home appliances like lights or TV.
Q:Solar Panel - DC motor - Rated Power ? Functionality ?
solar cells are not rated in mah, they are rated in ma or amps. I'll assume this one is 50mA. Two in parallel will give you 300mA, so that will charge a 800mA-hr battery in 800/300 = 3 hours. Theoretically, in bright sunlight if the array is exactly at right angles to the sun's rays. The problem is, depending on the type of cells, the battery pack will need 8 volts or so to charge, and your solar cells won't deliver that. If the sun is at an angle, you may get only 3-5 volts. so you have to put them in series, so you will get only 50mA out of them, which will charge the battery in 6 hours of bright sunlight. Would two of my solar panels run this DC motor ? If the motor is .8 amps, you need the battery, the arrays are not near enough. Or are you attempting to replace the battery pack with the solar array? Your english makes that difficult to understand. If so, put them in parallel to get the 300mA, but that would run the .8 amp motor very slowly. If you had 2 of the solar panels, it might run at close to full speed if the sun is bright and shining directly on all the panels. But where did you get the .8 amps for the motor? The 800Mah rating of the battery has ZERO to do with the motor current. So the answer above is based on your number, which I suspect is totally wrong. .

Q:Solar Panels for Home?
We just recently had Pursol Solar Systems install some solar panels for our house. We got ours with no money down, found them online, and they happen to be in the same city where we live. Cool thing about switching to renewable energy is that you get tax break... government will actually pay for your solar panels! Also, YES ITS TRUE! You're meter will spin backwards because energy that's being produced that your not using, goes back to your energy provider (like selling it to them during peak hours)....
Q:How many solar panels do you need to power a house?
Here in southwestern Arizona more and more solar panels are getting installed everyday. If it wasn't an economical thing to do I doubt if people would be doing it. Given that because of climate change our summers are getting longer and apparently hotter running an air conditioner gets evermore expensive. Also every year or so the rates go up. At the current rate of increase rates will easily double in a decade. Installing a solar array means that in far less than a decade, given a hefty down payment, any government subsidies and tax breaks in a couple of years you'll own your own electric company. Technically about /4 of the US would benefit from a true government program to install solar panels on all buildings. Years ago it became law that every building had to have electricity, running water and flush toilets. We need a similar law to hurry up a conversion to solar where practical.
