Q: i attached a usb charger to my solar panel(it has an output of about .2 volts) but i read on my multimeter its only using about 8 volts however on the conventional wall charger that i use to charge it has an output of about 5. volts.... i believe that my mp3 player is not charging it does not display the charging icon when it is on or off ....is this becuase the output is higher ? do i need to install a volt dropping diode to prevent it from putting to much energy at once? (my mp3 charges fine on the wall charger but does not seem to respond to the solar panel so it the circuits are fine....): You description is not clear as to what is supplying and what is consuming the .2, 8, and 5. volts you mention. I get that your solar panel output is .2 VDC (volts DC), but is that open circuit or under load? Also, is the charger output AC or DC? What's using 8 volts? Circuits don't selectively use a portion of the voltage supplied. They use all or nothing. Is the polarity correct from your solar panel to your MP3 player? If your MP3 player requires DC for charging and you're feeding it the correct polarity, but too high a voltage, an overvoltage protection circuit in your MP3 charging circuit might be blocking the charging current from your solar panel. Go through everything again and if you need to post another question on YA, be specific as to what you're measuring, where, and whether it's the source or load you're measuring.

Q: Can solar panels be installed on a government building?: Yes, solar panels can be installed on government buildings. Many government buildings have started adopting solar energy to reduce their reliance on traditional energy sources and to promote sustainability. The installation of solar panels on government buildings not only helps to decrease energy costs but also contributes to the overall effort of transitioning to cleaner and renewable energy sources.

Q: Can solar panels be used to power an air conditioning system?: Yes, solar panels can be used to power an air conditioning system. Solar energy can be converted into electricity, which can then be used to power various appliances including air conditioning units. By harnessing the power of the sun, solar panels can provide a sustainable and cost-effective solution for cooling homes and buildings.

Q: Hi I need to replace the solar panel on my calculator and was wondering where I could buy one. Thanks in advance for your answers.: My suggestion is to first make sure that your calculator does not also use a tiny button cell. It could just be that the battery went dead. Also know that it's probably less trouble to just get a whole new calculator. If you have the skills to replace the solar cell, I'd suggest first disconnecting it, and wiring a .5 volt battery in its place. If that doesn't work either, maybe the problem is not the solar cell at all, but just its connection, or even a dirty ON button. As for where to get a replacement solar cell, if it were me, I'd go to a dollar store, and see if they have a cheap solar calculator that I could harvest one from.

Q: are solar panels just a photodiode?A Photodiode converts light into either current or voltage? Right?: Yes, so are camera sensors. Except in cameras they're specially desgined to reduce noise.

Q: Can solar panels be used in remote areas without access to the grid?: Yes, solar panels can be used in remote areas without access to the grid. Solar panels generate electricity by capturing sunlight and converting it into usable energy. This renewable energy source is particularly useful in off-grid locations as it provides a sustainable and independent power supply. With advancements in solar technology and the availability of battery storage systems, solar panels can effectively meet the energy needs of remote areas, even during nighttime or periods of low sunlight. This makes solar panels an ideal solution for powering homes, businesses, and infrastructure in remote locations without grid connectivity.

Q: Was looking at 0w solar panel kit. Does this mean, all I can use is something like a 0W CFL light bulb and nothing else?: Graham is on the right track. However, you need to factor in a 80% DC to AC conversion loss. But yes a 0W CFL is about the size of it... Harbor Freight sells a system consisting of panels, battery, inverter, and TWO CFL's for $250. (You can power 2 CFL's off the grid for a very long time for $250)

Q: Around this time here in Georgia we will begin to get some big storms with high winds. I have a solar panel on a mount that isn't all that sturdy and could be knocked over with any winds pretty much above 5mph. I can't put anything in the ground to do this. I used to have it mounted to the roof of a playground for the most sunlight, but because of the angle of the sun and the tree leaves, I have to have it on a quot;portablemount so I can move it throughout the day, and I can tell you one thing is certain, and that's that it isn't the most sturdy thing ever. I'll have it a little better next weekend but it'll still be able to easily blow in the wind. Should I just hang the panel along the wall during a storm then reconnect it to its base once it's over?I'm pretty good with wood, so any wood creations to help out with the thing would greatly help. Just please keep it on a low budget.: You have to make the decision weather you want it portable or stationary. If you want stationary I would make some good brackets for them / search for cheap ones on OKorder. I'd have to see them to be able to offer any better suggestions. It's always hard to decide so you'll have to take notes and do research.

Q: I really need to know about the good companies who are selling good quality home solar panels.I lives in Pakistan, solar panels sell here are cheap but they doesn't work for long time, mostly they are quot;made in chinaquot;.Consumption of units of our house written on our electricity bill is 300.My dad is seriously thinking of purchasing a solar energy system for house that long last and works efficiently.So plz help me out.: Are you looking for the best and Affordable Solar Panels?

Q: How do solar panels perform in cloudy weather?: Solar panels can still generate electricity in cloudy weather, although their performance is reduced compared to sunny days. Cloud cover reduces the amount of sunlight reaching the panels, resulting in a decrease in energy production. However, solar panels can still produce a significant amount of energy even under cloudy conditions, making them a viable source of renewable energy in regions with less sunlight.
