Q:Solar Panel Wiring in SERIES?
Stephen is sweet in you should adventure the enter criteria of your inverter. so that you'll want to cord a minimum of a few cells in series. probable you should custom-go with a blend of series and parallel for the cells. operating example, if maximum of your fragments grant a million amp, then you actual ought to objective a million amp for the array. If there's a fragment that's 0.7 amp, and yet another that's 0.3 amp, you should parallel those, and count number them as one cellular, that you'll then series with the others. I observed this performed on one individual's panel years and years in the past. It gave the impression of an poor mess, and extremely some artwork, because the cells couldn't be in neat rows, anymore. also, if plausible, you should want the utmost equipment voltage you should use, because meaning decrease amperage for an same potential, and to that end smaller cord. 8 amps, after derating, skill #2 or #4 cord, an same variety that must be used to cord your position. 5 amps skill #0 or #8, and one hundred amps skill a fat cord like the jumper cables for a vehicle. in basic terms so that you comprehend, i trust that's typically unlawful contained in the U. S. to connect a selfmade array to a grid-tied equipment, or to apply a grid-tied inverter that plugs into the wall socket, in case you care.
Q:Solar Panel Question?
I like TBS0's answer, but 5KW isn't going to hack it. We don't live life on the average. If you turn on the oven, the dryer, the iron, a bunch of lights, and the TV, you are going to shut the system right down. You should not count on running everything with solar cells, but the most critical circuits. And you are lucky to have 25% of a day in optimum solar alignment for photocells. You need to think outside the Al Gore crazy box. Our modern way of life requires a lot of power! If you switched to coal or wood for cooking and heating and ironing, sunshine for drying clothes, heating the hot water heater, and for daytime lighting, then you could use the photocells for some lighting and the washing machine and anything electronic. You might stand a chance.
Q:Solar Panel System companies at the swapmeet?
Hard to say. Solar panels are becoming more common these days. May want to ask if the vendor is licensed and bonded contractor (if he's doing installation as well as panel sales). Find out the name of the equipment that this guy is selling (panels and other hardware) and do a search. For that matter, get the guys name and do a search on it to see he pops up elsewhere.
Q:Why won't my solar panels drive a motor?
to do basic electrical experiments with solar panels and motors, it is necessary to have a digital volt-amp-ohm meter sometimes called a DVM (digital volt meter). What is the voltage that the solar panels give when the motor is not connected? what is the voltage when the motor is connected? If the motor resistance is too low, then the solar panels will not be able to supply enough current to run the motor and the voltage with the motor attached will be very low. It might take a bright light on the solar panels or direct sunlight.
Q:Will my off the shelf deep cycle battery I purchased at autozone work well with solar panels?
There are batteries particularly made for solar, such as the Trojan T05-RE . I think the RE stands for renewable energy. A deep cycle battery should work all right, although not quite as well. What you want to do is try out your setup first, with just one battery, and the panels provided. If this is one of those 45 watt kits, you may be surprised at how little energy you actually get from the panels. Increasing the number of batteries won't help, either - that's like getting a larger water tank, when you only have a trickle to fill it. If your goal is really to save money, the most cost-effective solar is the grid-tied type, with no batteries at all. That's what we have, and I've never regretted it.
Q:A Question about Solar panels?
You have to know the amperage to figure out the watts. Volts x Amps= watts
Q:Solar Panel Question...?
Nice enough idea you have there, but practical reality is waiting to bring you back to your senses. The appliances you want to operate take a lot of power. You would need an awful lot of solar cells or a very cumbersome windmill to provide sufficient energy for them. You will find that for a mobile kitchen, an ordinary generator running on gasoline or diesel will be much less expensive to buy and maintain, less trouble to haul around, and much easier to replace if necessary. Considering that propane will probably prove less expensive yet, go with that for as many appliances as possible.
Q:What capacitor should i use to store energy from a solar panel?
If you have a rechargeable AA battery (NiMH or NiCad) that might work. You're not going to get much power from that size array anyway, especially if it is not in full sunlight. A Farad (F) is ,000 times bigger than a milliFarad (mF), which is ,000 times bigger (stores ,000 times more) than a microfarad (mF). pF and nF are so tiny do not even look at them. With your size array voltage might not be a problem, but be sure to check that the voltage rating of the capacitor is less than whatever the array can make. Some people buy those solar yard lights, which seem to break often. You might be able to get some and use the contents for your project (pre-wired circuits).
Q:A good brand of solar panels for my house?
I didn't research this. I do know that you must install them on the side or area of the roof that receives the most Sun all day. You can get information at stores like Lowes or HomeDepot.
Q:Question about commercial solar panels?
In my experience working with solar panels, I've found that the panels themselves are robust and can last years. How that energy is transferred from the panel to perform work (sorry for the boffinism) is where the complexity emerges, namely due to the fact solar panels produce DC current, and nearly all of our electrical appliances use AC current. In most cases, solar panels will either send energy through a DC/AC inverter directly to be used for appliances, or stored in deep cycle batteries, then converted to AC using an inverter when the user wants to use his/her appliance. Now to answer your question: the solar panels will be fine, and could conceivably be in fine working order with AC current available IF... and I cannot stress this enough (namely through years of field experience dealing with solar powered scientific instrumentation that was working well and then mysteriously not working)... IF rats and other rodents haven't eaten through the wires. This is probably the most likely reason that a set of solar panels wouldn't be working in your given scenario. Hope this helps, and good luck!!
