Q: I have several 6v 4.5a sealed lead acid batteries. I would like to hook one of them up to a solar panel and have it stay charged from the solar panel all the time, but not overcharged. Is there a simple way to do this with an IC or something? I am only a beginner with circuits so I want it to be something very easy to make. Basically, I want it to stay charged all the time so it's available if I need it for a power out or something.Thanks.: What I would suggest is that you find a panel that is rated for 00 mA, at any voltage higher than 8 volts. A 2 or even 8-volt panel will do, because the voltage will drop to match the battery. Then I would get a diode to put in series with the panel to prevent the battery from discharging through the panel at night. That's called a blocking diode. At such low currents, a charge controller is not worth it. There is not enough power to overheat the battery, which is principally what a charge controller protects against in a larger system. Be aware that you could also simply plug a trickle charger for the battery into the wall outlet, at a cost of less than a penny a day in electricity.

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: Are there any government incentives or rebates for installing solar panels?: Yes, there are various government incentives and rebates available for installing solar panels. These incentives can include federal tax credits, state and local rebates, grants, and loan programs. These incentives aim to promote renewable energy adoption, reduce carbon emissions, and make solar panel installations more affordable for homeowners and businesses. It is advisable to research and consult with local authorities or solar energy providers to determine the specific incentives available in your area.

Q: What specification of solar panel would I need to power a laptop every day? I would need to use it for about 0 hours or so every day. I don't know anything about solar panels, but I am seriously thinking of getting one now and don't know who to ask.: I okorder / says they have DC to DC solutions from 2 V for most laptops.

Q: Can solar panels be installed on historical landmarks?: Yes, solar panels can be installed on historical landmarks. However, it requires careful planning and consideration to ensure that the installation does not compromise the historical integrity of the landmark. This may involve using discreet mounting systems or integrating solar panels into existing structures. Additionally, obtaining the necessary permits and approvals from relevant authorities is crucial before proceeding with the installation.

Q: Interested in buying solar panels to save on electric bill.Any government help plans?: Yes, okorder / Also, realize, that installing solar is generally not an instant-save proposition. You pay thousands or tens of thousands of dollars to get the system installed, then it pays you back over the years. You need to talk with a local installer to see if the financial case makes sense in your situation.

Q: Im doing a science project and I need to know what gases or liquids a solar panel can make that is not friendly to the environment. Please name all the gases and liquids and explain how they damage the environment. It would be most likely that you will get best answer if you find all the bad things about solar energy and explain why they are bad and how they affect nature. that would be helpful to. Thank you: Build okorder /

Q: Can anyone give me a simple but informative explanation on how solar panels produce electricity/power? Thank you!: solar panel absorb sunshine , and it will produce electric charger, the charger move to one direction, it wil produce electric current, so it produce electricity. the electricity can through cable move to solar battery to store or to country power grid to provide electricity for people using.

Q: Can solar panels be used in areas with high levels of bird or bat activity?: Yes, solar panels can be used in areas with high levels of bird or bat activity. However, to mitigate any potential risks to these animals, certain precautions can be taken. For example, incorporating bird deterrent features such as netting, spacing panels appropriately, or using specialized designs can help minimize bird or bat collisions. Additionally, conducting proper environmental impact assessments and considering local regulations can ensure the safe and responsible installation of solar panels in these areas.

Q: Can solar panels be used in areas with high levels of air humidity or moisture?: Yes, solar panels can be used in areas with high levels of air humidity or moisture. However, it is important to note that excessive moisture can affect the performance of solar panels over time. Therefore, proper installation, regular maintenance, and periodic cleaning are crucial to ensure their efficiency and longevity in such environments.
