- Q: Hey i am going to build a scale model house and demonstrate how you would use solar panels to provide energy. I am thinking of buying some kit solar panels and wiring up some lights to show how they power the home. Also i might hook up a battery in the house to show how you can store the energy. I might also have a large battery hooked up outside the house to represent a power plant that could provide emergency power. Any ideas or comments would be great. Thanks
- you have the right idea, but forget about so many batteries cause solar power replaces them. get some small solar motors and use them for ceiling fans, try some small xmas light in a box behind a picture to look like a tv screen, use the small solar motor to demo an exercise bike and use a 00 watt or better light bulb to power your solar cells in place of the sun. that would demo the idea best without the use of batteries. i really hates batteries, but i love me some solar. i am a solar engineer and i think that light is the most amazing element in our universe. solar energy was the first source of power on earth and it will be the last. oh, did i mention that it is also so very very free. in fact, solar energy is so free that one can not even buy a handful of it and one can not even steal a pocket full of it. aint that something to think about and to post on your project just for a fun fact!!
- Q: Hi.How efficienent are solar panels? I mean, suppose we install a kw panel.. Wil it produce 5kw in 5 hours of good sun light?Or like if its 80 percent efficient, wil it produce 4kw and so on.Also, do the chinese solar panels give the same results as compared with panels from other countries?I live in india, so we get plenty of sunlight during the day.Thanks
- Panels okorder
- Q: the solar panel works with LEDs, small bulbs,etc but neve with any dcmotor. Please help. I have a science exhibition.
- Because its not voltage related its current related. look at the start up values for the motor w respect to current. This will be listed in amps or milliamps. Then cross reference that to the output of your solar panel also listed in amps or milli amps... ;)
- Q: Can solar panels be used for powering outdoor signage?
- Yes, solar panels can be used to power outdoor signage. Solar panels harness sunlight and convert it into electricity, making them a sustainable and eco-friendly option for various applications, including outdoor signage.
- Q: Can solar panels be used in areas with high levels of dust or dirt?
- Yes, solar panels can be used in areas with high levels of dust or dirt. However, regular cleaning and maintenance of the panels may be required to ensure optimal performance. Dust or dirt accumulation on the panels can reduce their efficiency and affect the amount of sunlight they can convert into electricity.
- Q: What is the efficiency of solar panels?
- The efficiency of solar panels refers to how effectively they convert sunlight into usable electricity. Generally, the efficiency of solar panels ranges from 15 to 20 percent, with some advanced models achieving efficiencies of up to 23 percent. However, it's important to note that the efficiency can vary depending on various factors such as the type of panel, its age, location, and environmental conditions.
- Q: It measured volts before I attached it, and after attaching the voltage regulator device, the voltage dropped down to 3 volts, even when just measuring the difference in the solar panels nodes themselves, suggesting that the entire panels voltage dropped and not just the voltage in the regulator. I tried testing it with a power supply of 7 V 0. A and it works fine, but I don't know why it won't work for the solar panel.
- you cannot treat the open circuit voltage of a solar panel like a voltage source (like a battery.) the load response of the panel doesn't behave that way. small panels and panels that are producing less than about .5A are very happy to have their output voltage pulled down to whatever they're connected to (typically zero.) I observed the same phenomenon when i connected a 2V 725mA panel to a 2V 325mA fan -- the open circuit voltage of 5V dropped to 3V when connected to the fan, and returned to 5V when disconnected. The easiest workaround is to use 2V of rechargable batteries in parallel with the panel so that the battery holds the 2V potential difference and the panel just supplies the current. any excess current charges the batteries, so you might consider whether or not you need some type of charge controller to prevent burning the batteries via overcharging. there are actually very few applications of solar panels connected directly to circuits that i have seen that have any kind of robust performance -- if they work at all, they eventually die/burn themselves out in a couple of months. the best robust designs always have a rechargable battery and charge controller somewhere in the power circuitry to buffer the load circuit from the panel. .
- Q: I have four power packs for solar lights. They have 3 AA .2volt batteries of 2450 mAh capacity installed in series for a total supply voltage of 4 volt maximum for the lights. I want to charge all four packs at once off a single 6 volt solar panel. With the four packs wired in parallel, what capacity output (wattage) panel do I need to charge the batteries in an 8 hour day?
- WIRE THEM IN PARALLEL BUT MUST VIA ONE BLOCKING DIOED FOR EACH 4V BATTERY BANK ( LIGHT) BETWEEN SOLAR PANEL OUTPUT TO EACH BATTERY BANK. DIODE USES LIKE N5404 THAT CAN HANDLE 3A OR HIGHER IS BETTER. TOTAL AH = 9.8 AH FROM ALL 4 LIGHTS. NOT 25AH FROM YOUR MISTAKE RATE. TO CHARGE THEM FULLY IN 8 HOURS, CHARGING CURRENT AT LEAST .3A BUY SOLAR PANEL HAS OUTPUT 6V 2A ( OR 0W ) IS GOOD ENOUGH.
- Q: Im doing this project on Solar panels and im not so sure what they are!some questions i have are who invented them and what were they invented? If u could know anything on Solar Panels i would love to hear it. Thanks!!!!!!!!!!!!!!!!!!!!!
- Solar power is harnessed through solar panels. These solar panels consist of numerous solar cells. That helps in producing the electricity
- Q: I have two solar panels and I have measured that they produce V by themselves. I am trying to generate .5V, but whenever I hook them up in parallel I get something like .02V. What it happening?
- You are probably wiring them incorrectly: with the positive on panel A connected to negative on panel B; and the negative on panel A connected to the positive on panel B. If you want then connected in parallel, connect the positive on panel A to the positive on panel B and the negative on panel A connected to the negative on panel B. But you will only get vdc. You can't get .5 volts from two volt sources. You can get 2 volts by connecting the panels in series.
