- Q:my solar car works when using the Battery but when there is sunlight i connect the wires to the solar panel and it does not work...................HELP
- If that solar panel came with the car, the panel is most likely defective. Make sure you're in bright sunlight, and try holding the car so that the wheels are not touching the ground. If the wheels still won't turn, even slowly, then the panel is bad. If each person in the class got one, see if you can try your panel on a friend's car, or their panel on your car. If this is just any little panel, it could be that the panel simply does not have enough voltage, current, or both to power the motor on the car.
- Q:My project needs to build a thermal solar panel that would be used as a demonstrational rig. The dimensions i am allowed do not allow me to use a normal thermal solar panel so i have decided to use the heat exchanger from the back of a fridge. Although this is possible to use what equation would i use to prove the power of the sun would actually heat up the water. More importantly when the rig is demonstrated to students, they will need to be able to determine if the raise in temperature given by the thermometers is what should be given. Variables of the rig will include: Angle of the panel, Light intensity, Direction of panel, and more importantly the flow rate of the water travelling through the pipes. What equation includes those variables (change in temperature, flow rate) and would allow me to incorporate the angle of the panel. The light source would be a lamp so i would also need to know how much of the energy from the lamp is actually being used by the panel?
- solar panels don't store energy, they only generate it. If you want to store energy you need a battery bank of some kind to get you through the night and anytime the sun isn't shining. If you have a little extra in the budget you might look at a geothermal system for your home's heating and cooling needs. They're highly efficient systems and you can supplement however you like. Whatever you do, though I hope you have a good building envelope in place already. Solar panels are cool, but if you have a leaky house, you're still not getting the best out of your panels. Do the more mundane stuff first. Insulation, windows, and weather-tight doors.
- Q:I have an off-grid 24volt existing system using 8 x 80 watt 2volt, wired at 24volts, mono solar panels with deep cycle batteries,operating now. I have been given a 240 2volt polly cryst. panel. Can I add this panel to existing panels as above. Thank you, dumb solar man
- Assuming that you have / will upgrade wiring sizes to carry the extra wattage, that the new total wattage resulting from the addition doesn't overload any existing charge controller, diodes and / or inverter you have installed, then paralleling it straight into one of the other 2 volt groups should do nothing but add current to the system. True, it will be somewhat imbalanced, but it will work. Your other options would be to reconfigure everything down to it's native 2 V configuration which will raise current and lower voltage, with the additional panel creating the additional current to raise the wattage or to put it in series with the other 4 panel clusters so that you would get 36 V and additional current to account for the raised wattage. One last approach might be to set it up on another battery bank of it's own (small and at 2 V) to then connect to the same inverter. You'd be getting more power and storage capability that way, sort of a partial backup system, really, that will take some of the load off the other components to help extend their useful lives and get a bit more flexibility into it as well. The choice is yours here. That is all the ways that the system can be connected in, assuming everything in the first sentence checks out;-) It's difficult to make a recommendation without knowing what other components are in use and what the maximum ratings they carry are. Just remember that parallel connections add current and voltage stays the same, series connections add voltage and the current remains the same and you can figure out what to do with this thing to help you if you stay within maximum ratings for the charge controller, diodes and / or inverter involved. Good luck and stay safe!
- Q:Can solar panels be damaged by hail or other weather conditions?
- Yes, solar panels can be damaged by hail or other severe weather conditions. Hailstones can cause cracks or dents on the surface of the panels, which can affect their efficiency or even render them inoperable. Other extreme weather conditions like high winds, heavy snow, or lightning strikes can also potentially cause damage to solar panels. However, it is important to note that modern solar panels are designed to withstand a certain level of weather-related stresses and are often tested for durability.
- Q:how the power output of solar panels fitted to a house can chargenothing on the internet really answers this question, any information will really help..this is for GCSE, i don't really understand the meaning of the question. does it ask how the solar panel egts charged, and how it works? i don't get how you can charge a solar panel and is heat the only way you can produce electricity for it??please answer if you know! much appreciated!!! thank you so so so so so so so much, in advance =)
- Solar panels do NOT get charged, so the question is junk, or you misstated it. Solar panels are used to charge a battery bank, which stores energy for times when there is no sun. Then energy from the batteries is used, via an inverter, to power appliances in the house. OR do you mean how the power output of solar panels can CHANGE? In that case, they change when the sun moves, such as behind a cloud, or just changes angle in the sky, or goes out.
- Q:looking for alternative ways to save energy money and thinking about solar panels. anyone know anything about it and how expensive it is to install them?
- Installing okorder
- Q:Composition and function of solar panels
- Among them, for the electronic grade polysilicon accounted for about 55%, solar grade polysilicon accounted for 45%, with the rapid development of photovoltaic industry, solar cell demand for polysilicon growth rate higher than the development of semiconductor polysilicon, is expected to 2008 solar polysilicon
- Q:Can solar panels be used to power a disaster relief operation?
- Yes, solar panels can be used to power a disaster relief operation. They provide a reliable and renewable source of energy, which can be harnessed to power various essential operations such as communication systems, medical equipment, lighting, and water purification systems. Solar panels are particularly useful in disaster-stricken areas where conventional power sources might be disrupted or unavailable. They are portable, easy to set up, and can provide a sustainable energy solution during critical situations.
- Q:if u buy solar panels and never take em out of the box for like thirty years will they still work good thirty years after you bought them
- Most panels have a 20year warranty once on the roof (exposed to the sun). They will be fine
- Q:I have the wattage of solar panel but i dont know about the voltage amp; current rating of it. Plz explain me about the voltage rating of solar panel.
