Q:How many solar panels would I need to power my washer machine?
Solar panels produce power in proportion to the amount of sun light and inverse proportion to the temperature. To use solar power you will need in addition to the panels a bank of batteries a charge controller and an inverter to convert to 20v. The panel(s) will only be used to recharge the batteries and the batteries connected to the inverter is what is going to run your washing machine. You therefore need to know how long is the machine going to run, how often and how much charging can you expect to get from each panel in order to figure out how many panels you will need and how many batteries. If you do only one load very infrequenly, you will be able to use a smaller battery bank and charge at a lower rate.
Q:who knows about tax credits for solar panels?
Congratulations okorder.com/
Q:How can I adapt an automotive reglator to a solar panel?
solar panels will naturally produce a certain DC voltage which is what your battery needs - the current will vary based on the sun light. You need probably 4V to have some over voltage. So based on your specs look at having at least 4 V but not too much over that (tells you how many panels you need in series) I would have blocking diodes (probably the solar cell has them built in) to insure the battery does not discharge thru the panel.
Q:Why do solar panels stop working?
Panel degradation can occur in many ways, but they generally take a long time (40yr old panels are still working...). One problem is diffusion. Since the cells are at a finite temperature and receive energy from the light, atoms in the structure can migrate around the cell. If you mix up materials from either side of the junction, you can reduce or remove the internal field and so charge separation no longer occurs, meaning no more current output. This is generally a very, very slow process. My current research is on the back contacts of cadmium-telluride solar cells. CdTe forms a junction with metals, and this junction has a built in electric field that tries to stop the current going out of the cell. This is bad! It reduces the power you get out. To overcome this, copper is sometimes added. This really cuts down on the restrictions on current, but copper is very diffusive. Within weeks at room temperature it can jiggle its way along grain boundaries (the solar cells aren't one big crystal, but a load of small grains. Our lab makes ones about 0.006mm across). Whilst copper at the back contact is good because it cancels out the effect of the field there, once it gets to the cell junction it has a worse effect. It can act as a 'recombination centre' or 'shunting pathway' - it either absorbs the free charges or takes them somewhere useless and cuts the power output. Copper is a very obvious and quick acting cause of solar panels reducing in output. I believe a similar effect is true for other cells, just with different materials. The quality of the junction degrades slowly as heat and light give energy to atoms in the lattice and make them jiggle around a bit. Once you have things out of place, performance degrades.
Q:Have a question about mobile homes and solar panels!!!?
I was in debt up to my eyeballs, and I needed help fast, so I looked to some free online programs. I had tried so many that were scams, but I finally found one legit one! In two months, I paid off $3000 of my debt.
Q:What do you know about solar panels?
Solar power is produced by collecting sunlight and converting it into electricity. This is done by using solar panels, which are large flat panels made up of many individual solar cells. Using solar panels is a great way to generate clean and renewable electricity to power equipment or even the average home
Q:LED Lantern Charged via 6 volt solar panel?
If it has a 6 volt battery- is it marked 2 volts on an external plug? If so, there is a resistor inside to drop the potential the battery sees. The battery itself could be slipped out and recharged easily from your 6 volt panel. Just determine how much current (in Amps or Milliamps) the panel produces nominally and divide that into 4 and add one fourth of that length of time to make up for system losses. This will tell you how many hours it should charge assuming your starting voltage of the battery is above .5 volts. and the panel is at 3 volts potential or higher. So if your panel puts out amp at 0AM, you would charge for 5 hours. 4 divided by is 4 and one fourth of that is so 4 plus is 5. It is a little more involved than that, but as a rule of thumb. Also do not discharge tha lantern to the point of no light output. LEDs are efficient, but their current will add up. If it is suggest to be able to use the lantern for up to 8 hours on a charge, stick to that value. Lead acid batteries have best longevity when discharged only to 80 percent capacity. Once battery is charged- disconnect from charging source.
Q:What is the principle of solar panels work?
Solar power generation There are two ways of solar power generation, one is the light - heat - electricity conversion, the other is the optical - electrical direct conversion.
Q:What specification of solar panel do I need?
I okorder.com/ says they have DC to DC solutions from 2 V for most laptops.
Q:Should we subsidize solar panels?
Recent investments into solar panels have brought about a couple of interesting realizations and developments. One, as you state, is that traditional solar panels (silicon crystalline panels) are not currently cost effective, even will full-scale manufacturing production. It's possible that improved manufacturing techniques will bring the retail price down somewhat, but it needs to be brought down a lot to make economic sense without incentives. The other, though, is that a new method of producing solar panels - thin film technologies - has been developed. These are currently quite expensive, but because there are no crystals to grow, they are expected to drop significantly in price as production increases. I believe that this technological development has been made as a direct result of government support for solar energy. It is not taking money away from research - rather it is providing the incentive for research. I could be wrong. I've been wrong before. But I think that these new solar technologies, which are already hitting the market, will dramatically change the economics of solar energy.
