Q:Do solar panels plug into an outlet?
They are powered by the sun. You set them up out side of the house or on the roof and the sunlight shines on them through out the day. It stores the energy into light so when you turn on a light it is from the sun's energy. Plus it can save you on electric bills.
Q:How can I power 5v or .08 amps in a remote loaction via solar panel.?
First things first. 5 Volts @ .08 amps would be .2 Watts. therefore you would need at least the same amount from a solar panel to replenish the batteries. But what puzzles me is the notion that plugging it in a wall outlet ? If you use 20 V @ 0.08 then the power consumption is 9.6 Watts And what is a meraki wireless repeater? I never heard of one. I'm a FCC licensed Ham and have some idea what is available. If you need 5 volts DC, you could use twelve Ni-cads in series and just keep them trickle charged with the solar panel That would make it compact. If you were to use an automotive battery (or motorcycle), then you would need a DC/DC converter.
Q:Need help with building a project involving solar panels?
Solar panels are designed to be used to recharge a battery or series of batteries, not for direct power. That is the inherent weakness of solar systems. The only way to have it work in low light conditions if to have several cells wired in series and have a voltage regulator to limit the amount of voltage that can be supplied. Other than that, add a battery and a charging circuit that the cell would supply power to.
Q:Can a solar panel work with an inverter?
There could be a couple of reasons why it isn't working. First, 2V panels actually put out a considerably higher voltage because it is presumed that they will be used to charge a 2Vdc battery. That requires applying a voltage greater than 2Vdc, and usually there is a solar controller that regulates the solar power to the battery. It also has a voltage drop. Look at the first reference reference, and you will see these values for a particular panel: Voc: 2.6V (open circuit voltage) Vmp: 7.2V (voltage at maximum power point) Voc is the voltage the panel produces under standard sunlight and temperature conditions (25°C), with no load applied. As load is applied, the voltage drops (see reference 2). Power is the product of current times voltage, so at one set of conditions (namely at Vmp) maximum power is available from the panel. Your inverter might not be working for either of two reasons: ) it has input protection circuitry that locks out operation when it senses an overvoltage, as in the 2.6V open circuit voltage, or 2) the panel does not produce enough current and the voltage from the panel collapses under excessive load. For example, if you load your inverter to 20W, then nominally the 2VDC input to the inverter must supply 20W/2V/eff = 0A/eff Assuming the inverter has an efficiency of 80%, the input current required is: 0A/.8 = 2.5A A solar panel operating at maximum power would need a rating of about: 2.5A x 7.2V = 25W Is your panel that big? The other option, as mentioned by others, is to charge a battery that runs the inverter. Other nuances: Voc increases as temperature decreases. Sunlight intensity varies (obviously), so the panel may produce less than rated power. The power specifications often are printed on the back side of the panel.
Q:Solar panel charging question?
It is related to the size and capacity of your battery.
Q:how do i pick out solar panels to match my battery bank?
If okorder.com/... yet, it's worth browsing the off-grid section. 8 peak equivalent sun hours a day on average is very achievable with tracking, but are you sure you really want to spend on tracking? It's a lot of trouble and expense - might be cheaper just to get more panels. Also be aware that when you have a lead-acid battery bank capable of (say) 000 Ah, that is the capacity that the batteries could supply as a one-shot deal. If you ever took that much from them, they would be ruined. Typically, you would try to take only 20% of the capacity before recharging, although some batteries let you take 50%, with reduced life. Have you considered wiring the batteries as 36 volts? There would be more efficiency, and less problems with equalizing the batteries when charging. Unless 2 volts is really the output that you need most. Sorry to redirect you, but I can't recommend that forum too highly. Lots of considerations.
Q:Does anyone know a company that will make custom solar panels?
okorder.com Other sources available on the first Link also. Wingman
Q:how to store energy from solar panels?
If you are buying a kit, chances are there is an instruction manual in there on how to mount your solar panels. You can also ask for assistance from the store.
Q:hi i am asking about the life of solar panels?
For mono-crystalline solar panels, most warranties guarantee 90% of the original efficiency when the panel has been used for 0 years, and they guarantee 80% of the original efficiency after 25 years of use. If the original efficiency is 5%, the efficiency after 0 years of use should be 3.5%, and the efficiency after 25 years of use should be 2%. Some people believe that the actual average rate of efficiency loss is slower than that. You might retain 85% of the original efficiency after 25 years, making the average efficiency drop about 0.6% per year. After 75 years, a solar panel that was originally 5% efficient might still be about 8% efficient.
Q:Do solar panels add to global warming?
Third Law of Thermodynamics (in normal speak): “Not only can you never get ahead, you can’t even break even.” This is a truism that applies to all activities involving energy exchange (and almost everything else as well). Energy in the form of solar radiation falls on the earth. That energy is absorbed by the planet (everything) and heat results. Some portion of that energy is lost in the absorption process and the net released as heat is less than that absorbed from the sun. This is true in all cases. Solar panels, both photovoltaic and heat collectors are subject to the Third Law and they all lose some of the radiant energy striking them in the process of converting that energy into either hot water (or whatever fluid) or electrical energy. Regardless of the process there is always a net loss of energy. The time delay you mention has no bearing on the total heat gain or loss for the planet. In fact the “solar panel effect” reduces the net energy put back into the ecosystem because it introduces another iteration of energy loss through conversion. The Holy Grail of energy conservation it the ability to use, store or recover the entire amount of energy produced regardless of the source of that energy, burning hydrocarbons, geothermal heat exchange, solar radiation, mice on treadmills …..all forms of energy suffer a net loss in any exchange! If we could avoid that loss we could dramatically reduce the heat lost into the atmosphere or ground water and our net energy gain would also be dramatic! Check out the super cooled circuits in use to reduce resistance in sophisticated electronic equipment for a good example of the energy savings. (Of course the savings do not account for energy lost in the cooling process. In any event NO….. solar panels do not contribute to global warming via their operation. (Their manufacture is another story altogether!)
