- Q: What size of system would I need to get if I use on average 500 kilowatt hrs a month I would like to do a tie in grid system I live in the states south central area of States any info or links to sites would be wonderful I am interested in this type of energy soure thank you
- First find out from your electric company whether they allow grid tie systems. IF so then they can help you figure out what you need.
- Q: I really would like to have my own solar panel, but i don't know how. Most of the panels i have looked at are for car batteries but i'm not sure how this would be able to be transfered into electricity. I'm looking to power things like lamps, a stereo and various chargers for phones and ipods. Please explain to me how i could adapt a solar panel to my uses. Thank you.
- Sounds okorder .. I've seen the particular device listed there. While the lamp is mediocre for an LED light source, the panel is excellent - real polysilicon wafers, in an aluminum frame. Same construction as the kind of panels in commercial installations.
- Q: Can solar panels be integrated into windows?
- Yes, solar panels can indeed be integrated into windows. These specialized solar panels are called solar windows or photovoltaic windows. They are designed to function as both windows and solar panels, allowing them to generate electricity while still maintaining their transparency for natural light to pass through.
- Q: We are thinking about useing solar panels for our house.Does anyone know about solar panels? If so could you please tell me some information on them,and the cost for a home,to install them.
- If solar power is not practical, why do four of my friends and I have it? Actually Don M is mostly right. The factors to consider when contemplating a solar installation are numerous. For example my system will not pay for itself in utility savings in my lifetime, but I plan to sell the house soon. What I am saving on electricity costs, and the increased amount I can ask a buyer, I will come out well ahead. Cruise the Internet and look in the green search box at the top of this page, for solar panels. As you learn more, you can come back with more questions.
- Q: I'm a student trying to design a mounting structure for solar panels. I'm reading about passive trackers so as to track the sun for optimal energy production; but I am not fully quot;seeinghow it works. Can someone please help explain it to me, or at least send me a link(s) that could help explain it well?THANKS IN ADVANCED!! [and HAPPY HALLOWEEN!!]
- It appears to be relying upon a phase change of liquid to gas to liquid to balance the system and return it to the east in the morning.
- Q: Hi everyone, I am a novice in solar energy system. I want to know if I am on the right track. Recently I bought a 30 W solar panel, 5 Amp controller, and a 22 Ah battery, how many watts and what kind of INVERTER do I need? I did an research some said 50 W and some said 300 W. And am I right on the 5 amp controller and 22 Ah battery to provide larger output of electric, or the higher the # the greater output for 30 W solar panel?Really appreciate for anyone who help!!!
- With a 30 watt panel, producing about 2 amps, your not going to have much power from that. A 22 AH battery will give you 2 AH of usage. A battery should never be drained below 50%. What this works out to be is simply Amp draw for 2 hours. Which equals to 2V light bulb that draws amp for 2 hours. Not much. Now to replace that usage with your 30 watt panel, provided the panel is clean and in max sunlight, it will take 6 hours. If you attach an inverter to your system for 5 Volt Usage then the DC voltage drawn from the battery is very high. Example: Say you use a 5 Volt component that requires 50 Watts per hour to operate. The inverter will draw 5 Amps out of the Battery every hour to operate that component. That gives you and /2 of use before the battery is down to 50%.. Maybe that will be enough to charge up a standard Laptop battery. I have 2 30 Watt panels that produce 5 Amps, 4 6V batteries that have 480 AH and a 25 Amp Controller with a booster that increase the amp output to 20 Amps per hour. I live full time in an RV and raise the panels to get max output when I am parked. This system provides me with all the 5V throught the 500 Watt inverter that I need. Good luck on you system.
- Q: We see increasing, what appear to be, solar panels on electric poles?
- Usually they are used to power monitoring units that transmit data to a central point on usage and/or line loads. They may also be used to supply power to some control circuits, and to allow remote control of these units. (If there was no power in the line, how else could you supply the needed power to obtain information and/or control these things remotely.) What they do is keep a standby or backup battery charged to operate the equipment. They are also used for self-powered lights in many areas, charging batteries during the day to run the light(s) at night. Similar systems are used on monitoring wells to transmit water table data. (Faster, cheaper, and more timely than sending someone around to make checks and read equipment once every couple of months.)
- 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: How long does it take a 5 watt, 2 volt solar panel to charge a 2 volt R.V. battery?
- depends on the sunlight. And on the size of the battery. But it may never charge, as you need at least 5 volts to charge a 2 volt battery. So unless the sunlight is bright enough to generate 5 volts, all you will do is discharge the battery through the solar panel. But a large battery is 00 amp hours of capacity. Even if you had a 5 volt 5 watt panel, that generates only amp at most, so it would take over 00 hours to charge that size battery. .
- Q: Hello,What do you all think about the future of solar panels and what role they will play in the near future. There is tons of money being dumped into the industry and demand is slowly rising. Also do you have any favorite solar links to get more info about them?
- Well I think solar technology is a viable solution to our energy problem. The only issue is that right now it takes too long for the panels to pay off unless you have a fairly big facility to power. Solar panels are getting cheaper and cheaper though, soon they will pay themselves off in less than ten years and I think then you will see more people buy them which will bring the price down even more. Solar done on a large scale is something that needs to be invested in ASAP. They can create jobs, power our nation and slow down global climate change.
