Q: What is the purpose of solar panels?: The purpose of solar panels is to harness the energy from the sun and convert it into electricity, providing a renewable and sustainable source of power for various applications.

Q: Can solar panels be installed on theme parks or amusement parks?: Yes, solar panels can be installed on theme parks or amusement parks. In fact, many amusement parks around the world are increasingly adopting solar energy to power their operations. Solar panels can be installed on rooftops, parking lots, or even integrated into the design of rides and attractions. This helps to reduce the parks' carbon footprint, lower energy costs, and promote sustainability in the entertainment industry.

Q: So, I've seen cheap solar panel kits for sale from Harbor Freight, and regardless of whether or not I were to buy a set from them or someone else, I was wondering what the process of implementing a small-scale solar system into your household electrical system would be.I've read articles that started out too in-depth or were speaking of systems on a much larger scale.Can it be as easy as buying the panels and inverter, and plugging it into a socket, or is there more to it?Some of the articles I was reading had mentioned having to contract with your electrical supplier, having to have an electrician tie it all in in some special/ necessary way, using a battery pack (would this be necessary for a tied-in system?), or using the system to only power single items, like a water heater, or plugging items into a connected battery-pack, all of which I'm not sure is necessary or needed for what my goals/ means are/ would be.: Solar panel produces DC power that cannot be used directly by any electric device at house. Besides, it produces very little current unless its size is big as your roof. To convert DC power into AC power requires even more investment, like a huge storage rechargeable battery bank and very high power DC to AC converter . That is not worth to try it to supply whole house electricity with solar power . That might cost you at least U$20,000 to start with and never ended weekly maintenance. You could only try it just for fun to let it light up a few LED directly without the need to add any extra parts to it.

Q: I have a 20 watt solar panel that I want to set up. I need to connect it to the solar controller but do not know what cable to use. I plan on adding more solar panels down the line. What would be the best cable to use?: How long is the run? 2 gauge is a good choice for runs up to 25 feet at 20 watts, if you are much further in your run, move to 0 gauge to reduce resistance of the wire itself in the circuit. Otherwise refer to the prevailing electrical code of your local unit government. This is a must if you plan to maintain insurance. At lower voltage, a little resistance means a lot. 4 gauge might be okay for 20 VAC, but the voltage drop on a low voltage system from resistance of the wire itself is measurable at 20 feet. It is the difference between a light fixture working or not. If you are planning on adding additional panels in the future, you can get terminal buss with screw hold downs at various vendors like Mouser or Digi key. Each panel can be on it's own screw, while the buss is common on the other side of the connection. one for the positive and one for the negative.

Q: I mean like bread is made of wheat, what are solar panels made up of?How are they manufactured?: Solar panels (aka photovoltaic panel) are most often made up of thin wafers of crystalline silicon or cadmium telluride. As photons from the sun enter the photovoltaic cell, electrons are freed from the substrate when are then collected by wires that run throughout the panel. And as we know electrons=electricity!

Q: if I have a battery bank of of 6 L-6 Trojan batteries, 6V 390AH, wired in series parallel to give me 2V at 70AH (or 4,040WH) what kind of solar panels should I purchase assuming I have 8 hours of sunlight, a solar tracking system and I want to make sure I can fully recharge my batteries everyday if i use up all the power every night?i understand there are efficiency issues to consider which i have not calculated in yet. thanks.: If okorder /... 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: I have an electric bicycle that I travel to work by, pulling a modified child carrying trailer that holds two 2 volt deep cycle batteries in series to power the 24 volt bike motor. I'm thinking about adding a 50 watt solar panel (or larger depending on the room I can make available) to charge while I'm at work and to provide some extra juice while on my more distant travels.Can I get a solar panel to charge them while they're connected the way they are: in series? Does charging work that way?I've read that in order to charge the 24 volt battery setup (if the answer to the Q above is yes), the output from my solar panel would need to be a little more than 24 volts. Is this true? If so, how many volts?Since the bike is supposed to be powered at 24 volts and I have an x-volt (x gt; 24v) solar panel connected to it, will this cause any damage to the controller or other components while running them?Will it help supply power even while the motor is being run?Thanks.: You did not give the AH rate from your 24V battery pack,therefore , unable to suggest a correct current rate solar panel. The solar panel open voltage rate at least 30V to charge a 24V cell. No harm to controller since the charging current is so small even bike is in running condition.

Q: i was told that by making a solar panel they cause more pollution than they will end up getting rid of. Is that true?: The amount of energy needed to extract the raw materials from the Earth exceeds the amount the finished PV panels produce.Processing the materals takes additional energy.After manufacturing they have to be transported.Photovoltaic panels only generate </2 volt per square inch in bright sunlight.They become less efficient when they get dirty.

Q: What is the proper diode to use on an 5v 500ma solar panel?: At least a 2 amp diode. rated above the 2 volts that are commonly found on the market. A blocking diode must be able to stop a higher current and voltage than the panel maximum. A diode will work on any voltage and current lower than it rating.

Q: I got an 8v solar panel for a project today, the only problem is that it came without any wires attached to it. Now i don't know what type of wires i should use and if i should solder them on or if i should use epoxy instead. Can anybody help me out?: You might want to be careful about soldering. Some panels can be easily damaged by excess heat. Check the manufactures website for recommended attachment methods. Solder tape or conductive epoxy might be better. If you do not have such things already, a good idea might be to take it into a TV repair shop or electronic hobbyist store. Some folks are kind enough to do it for you for free.
