FAQ

Yes, there are a few disadvantages to using solar panels. Firstly, the initial installation cost can be relatively high, making it a less affordable option for some individuals or businesses. Additionally, solar energy production relies on sunlight, which means that solar panels are less effective during cloudy or rainy days, or at night. This intermittency requires a backup energy source or energy storage system, adding to the overall cost. Moreover, solar panels require a significant amount of space for installation, which may not be feasible in densely populated areas. Lastly, the manufacturing process of solar panels can have environmental impacts, as it involves the use of certain materials and chemicals. However, it is worth noting that continuous advancements in technology are reducing these disadvantages, making solar panels an increasingly viable and sustainable energy solution.
Solar panels can actually help extend the lifespan of a roof. They act as a protective layer, shielding the roof from harmful elements such as UV rays, rain, and snow. Additionally, solar panels can reduce the temperature of the roof, which can help prevent heat-related damage.
I want to use this solar panel to hook up AC adapters. IM not sure what to do and how to use the solar panel. I want to be able to use a batter charger, a radio, and charge a GPS if needed. - Thanks, Zoo
You will need a charger controller, a 2 volt battery and a inverter to convert the 2volt dc to 20 volt ac. Your also going to need about 0 more solar panels of the same size!
I am planning to run a couple of dc motors on solar current. I have a couple of 450mA 4V, 200mA .5V, 00mA 9V solar panels with me. I need to run a pair of .5A 9V motors. Suggest me a circuit along with other equipments I might require. For your info, I am trying to build a solar powered drone / UAV
I don't think it is enough solar power. Your motor requires .5A x 9V = 3.5 watts. The solar cells are .450A x 4V x 2ea. = 3.6 watts, .2A x .5V = .3 watts, .A x 9V = .9 watts total solar = 4.8 watts. The problem with connecting the cells in series to get the right voltage, like the two 4V cells in series with the .5 volt cell (total 9.5 volts) is that the .5 volt cell limits the maximum current to only 0.2A. If you paralleled that with the 9V cell, you would get 9 volts at 0.2 + 0. = 0.3A, too low to operate the motor at its design current and voltage. The best you could do is put the two 4V cells in series, and in parallel with the 9V cell (a blocking diode might be a good idea, but probably not required for such a small array). That way you get 8 volts at 0.55 amps.
I'm looking into buying solar panels, there are all kinds of ranges of energy output...but my question is, when ti says...say 50 watts of power...does that mean 50 watts a day, an hour, a minute, what?
A 50-watt rating means the panel will produce 50 watts as long as the standard conditions are maintained. So if you had this bright sun and cool temperatures for 6 hours, the panel would deliver 50 x 6 = 900 watt hours, or a little shy of kilowatt-hour. Kilowatt-hours (kWh) is the reading on your electric bill. However, like most advertising, the 50-watt number is not realistic. They assume that the air surrounding the panel is very cold. 25 watts is a better number to use for this size of panel for engineering purposes.
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.
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....)
Have okorder . This could undoubtedly assist person!

Sure!...did you ever use a solar powered calculator indoors under a lamp?? It works just fine.
