- Q: I have two solar panels that were going to be trashed at work. I want to use them to charge batteries on my RV but i noticed they put out around 20 volts in direct sunlight. So i am wondering: -isn't this way too much voltage for a 2 volt system? -do a need some sort of a regulator connected to keep them from overcharging?

- Q: Are there any disadvantages to using solar panels?
- 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.
- Q: For a computer technology project we are using solar panels and trying to see different methods that will increase the output of solar power from these panels. For now, we have got polymer stickers and mirrors. Are there any more methods, or information that increase the solar power? Please and thank you :)
- I am a senior in highschool and one of my classmates is basically a genius by all means that I can tell. He has already been accepted yo UNC Chapel Hill. His admissions statement was on exactly this subject. I proof read it for him. Anyways the basic problem with solar energy is that we can only harness about 20- 35 pecent of the energy and even less of that is converted into energy that can acutally be used. His argument is that if somehow we could harness chloraphyll which is the chemical which plants use to harness the suns energy and incorporate it somehow into our solar panels. We could harness up to 95% of the suns energy!!! Id deffinately look into this.
- Q: I'm just geting into electonics and stuff. So I am trying to make a simple USB charger. I'm looking for at least 4 volts output. What I've got is two solar panels (detached) a 4 AA battery holder, and a circuit board with an led on it (took the solar panels out of old lawn lights. I need more charge out of my panels (I think) so I tried attaching them. I soldered the positive wire from one to the positive connection on the other and negative wire to negative connection. After doing so and checking the multimeter, it says I have no output at all. How do you connect them?
- Huh? you should have got something, in full sun, you should have gotten 3 or 4 volts, but milliamps in current. By connecting them pos. to pos., neg to neg,(paralell) it increases the current output. If you connect pos, on one, to neg. on the other, and measure between the remaining pos, and neg. you should have twice the voltage (series). You need 4 volts, but 4 AA's in series is 6 volts. If your going to use the panels to charge the batteries, you'll need a diode in series to prevent discharge during dark conditions, which the LED will work for.
- Q: Can solar panels be used in areas with high levels of dust storms?
- Yes, solar panels can be used in areas with high levels of dust storms. However, it is important to regularly clean and maintain the panels to ensure optimal performance. Dust storms may cause a temporary decrease in energy production, but it can be mitigated by implementing proper maintenance practices such as cleaning the panels and installing protective measures like dust shields.
- Q: Can solar panels be used for powering an airport or transportation hub?
- Yes, solar panels can be used to power an airport or transportation hub. Solar energy can be harnessed through photovoltaic cells in solar panels, which convert sunlight into electricity. By installing a sufficient number of solar panels on rooftops, parking lots, or open spaces in these facilities, it is possible to generate enough clean and renewable energy to meet a significant portion of their power needs. This not only helps reduce carbon emissions and dependence on fossil fuels but also lowers operating costs in the long run. Many airports and transportation hubs worldwide have already adopted solar power as a sustainable energy solution.
- Q: Can solar panels be used for camping or outdoor activities?
- Yes, solar panels can be used for camping or outdoor activities. Portable solar panels are designed to be lightweight and easily transportable, making them ideal for powering electronic devices and charging batteries in remote locations. They harness the sun's energy to generate electricity, allowing campers to have a reliable and sustainable power source while enjoying the outdoors.
- Q: Can solar panels be used to power a waste management facility?
- Yes, solar panels can be used to power a waste management facility. Solar energy can be harnessed to generate electricity which can be utilized to power the operations of a waste management facility, reducing reliance on traditional energy sources and promoting sustainability.
- Q: Can solar panels be used to power a camping trip?
- Yes, solar panels can be used to power a camping trip. They are a sustainable and portable energy source that can be used to charge electronic devices, power lights, and even run small appliances while camping.
- Q: For part of a school project how would I charge a car battery with a solar panel? The panel is 48V and 6A. This needs to be low budget so I can't buy an expensive controller, Is that the only way or are there other ways of doing it?
