Q:Why do solar panels produce zero energy?
Solar photovoltaic panels are highly inefficient to begin with. There are a few possible reasons why it does not produce energy even in the summer . Wrong inverter is used 2. The angle of installation (azimuth and tilt) is not optimum to capture the sun Solar photovoltaic panels are expensive and inefficient, and will not survive in the long run.
Q:Is there a personal use solar panel?
You can cosider this product Flexible Personal Solar Panel. I think it will be helpful. Product Review Take the lightweight, easy-to-pack Brunton Solaris 6 / 2 Solar Panels on your next expedition to the Himalayas or down that nearby trail or dirt road. Brunton used CIGS, the most efficient thin-film solar technology available, to create the Solaris. Choose either the Solaris six-watt or 2-watt panel—both of them fold up to the size of a CD wallet and work, even in overcast conditions, to charge your cell phone, digital camera, camcorder, iPod, and other small electronics. A built-in reversing diode prevents the solar panel from discharging your batteries when the sun disappears for the night. Brunton's Solaris 2-watt panel can even charge your satellite phone or trickle charge your laptop.
Q:who would win in this battle?
Solar panels for energy. Wood for building a structure.
Q:Why do glass covers improve the efficiency of solar panels?
For a solar thermal panel, the idea is to get the inside as hot as possible. There are three ways to lose heat - conduction, convection, and radiation. By cutting off airflow, the glass cover reduces cooling by convection.
Q:how much money does solar panels save?
I can tell you for a fact you can save money with solar panels. I have a system. I have a 3.74 kw dc system which cost $26K, I got a $0K rebate from my utility and a $2K fed tax credit. I will break even or get ROI in 6-7 years. My system generates about $2K of energy per year. The benefit of a school is most of the energy will be produced during the time that the students are using the facility so you may see a better return. I still use much of my energy when the sun goes down. All businesses get a 30% fed tax credit when they install a system, and many states offer larger rebates to businesses. There are many factors that will determine the efficiency of the panels, my orientation isn't ideal so that drops my production a little. Shade can reduce the number of hours a panel can produce. The number of hours of sunlight and the number of days it is cloudy can affect production as well. Your utility policies can have an economic impact, not all utilities allow the meter to run backwards or buy back the excess energy you produce, most schools are out of session during the longest most productive days. The biggest problem for solar is the large initial payment, without grants or loans it is unlikely a school would have the money to put up a large system. There is no need to zero out the bill, even a partial system can save money.
Q:Can we cover up solar panels on our house with regular siding?
I took mine out to prevent any future problems. Covered the holes with plywood.
Q:What is maximum system voltage in solar panel?
System voltage is the total across the full chain of panels, when using multiple panels in series. It's what the insulation on the panel is rated to stand, to earth/ground, without breaking down. A device could have an output rating of V and still a 000V insulation rating. eg. if your 0W panel had an open-circuit voltage of 25V, the insulation is rated to stand up to 40 panels connected in series. (40 x 25 = 000V). And actually a 0W power source could be rated at 000V, if it's current rating was only 0 milliamps. (Though extremely impractical for a solar panel unit).
Q:Need Solar Panel Guru.....?
With your load, the largest system on the page I reference above would not power your entire house, if all the AC units are running. However, how often does that really happen? You need to look at your utility bill and find your actual amoutn of KW hours of electricity used in a year and you hav enot told us that. The base price of top system quoted here without incentives is over $70,000. As you can see, the lions share of incentives is the utility company followed by federal. I have no idea if your local utility company offers incentives or not. You would have to resolve that with them. However, the federal incentives are still there even if your state and local utility has none. However, the price to you goes way up without all of these incentives. And your idea of using windows to mount solar cells is totally impractical. Yes, I know there are web sites that advertize just that, but it is total BS. The first word of advice to anyone looking to do this sort of thing is to FIRST have a complete energy audit done and then do whatever they say to conserve as much energy as possible, thereby reducing your need for solar power. Only then should you look at using solar to cover part of your load. We are a foster family and have adopted 5 children< WOW! I would like to thank you for what you do.
Q:2v about 600ma Solar Panel?

Q:Can a solar panel be used as a NiCd cordless tool battery charger?
Your 5W solar panel has to put out about 5 volts or higher to charge a 2 volt battery. 5 watts at 5 volts is only 0.3 amps, which is only enough to handle the internal leakage inside a large battery, plus a bit. If you have a 00 amp-hour battery, that panel would take 300 hours of bright sunlight to charge it. But I do agree that it will keep the truck battery charged as long as it gets sun. Make sure you put a diode in series between the panel and the battery to prevent the battery from discharging through the panel when the sun goes behind a cloud. I'd be worried that if you charged the 8 volt battery frequently, the panel would not be able to replace the lost charge, and your 2 volt battery would wind up discharged. That 8 volt battery is .2 amp-hrs (if I got the correct one). That is 27 watt-hours. Allowing for losses, you car battery will have to deliver over 30 watt hours to charge it. Your solar panel will take over 6 hours of bright sun to make up that difference. That is over 24 hours this time of year. So if you recharged it more than once every 2 days, you will lose charge in the truck battery. .
