Q:What Size Solar Panel Would I Need?
It sounds like saving money is your chief goal. If your house is not already super-insulated, that should be the first target. Super-insulation, radiant barriers, double-pane windows, white roof, weatherstripping, attic fan. Number two would be conservation. Can you turn the A/C up to 80? I visited a place in Wyoming when it was 0 outside, and 80 felt very pleasant. Third, efficiency. Have you considered a ground-sourced heat pump? Deep down below your house the water table may be colder than 40 degrees F, and can provide good cooling. After all that, you can look into solar electric, which may or may not be a good deal in your area. The type of solar electric that is most cost efficient is the kind that connects right to the house wiring and works alongside the normal electric company. You can talk with a local installer and get a free financial analysis. Then you can look at it and see if the installer is on the level, or trying to play accounting tricks with unreasonable assumptions. Solar makes sense in most parts of California, but Illinois is not known as a big solar area. The kits you have have seen were probably for standalone solar, generally an expensive proposition for the amount of power you get. Put another way, either it will be low power, or it will be very expensive.
Q:Has anyone gotten their solar panel rebates in Florida?
In case you hadn't heard the state is broke.
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. .

Q:What is so great about solar panels ?
Solar panels are eco friendly, they produce with out disturbing the enviroment. Instead of having to build dams and kill of species that have water homes we can use the sun as our energy source. im all for solar panels i hope this helps :)
Q:5kw Solar Panel Roof Kit?
This is dependent on sun angle, clear sky, shadow interference, clouds, etc. First if you purchased the PV panels and they are rated for 5 kW, the factory rating is based on a particular incident energy, 000 watts/square meter, 25 degrees C and an AM of .5, reaching the panels. It is more likely that you will not obtain this same level in the open air. If we assume you will get 80%, then the maximum kW would be closer to 4kW. This will be produced during peak, clear days with the panels placed perpendicular to the sun at all times during peak radiance times. When the sun first comes up and later when it is going down, there will be more than the thickness of .5 atmospheres between you and the sun, so the radiant energy hitting the solar panels drops off. Total energy is watts time hours. I would expect you PV system to produce about 750 kW-Hr of energy during a clear summer day at peak solar height. Hope this helps, NewtonLaw
Q:Opinions on Solar Panels?
I have a boat in a sunny place and four 80 watt panels. These will run my fridge Tv and a few LED's. I still have to run my engine for hot water and washing machine. My Batteries only last a few years and are a real pain. I go on the mains when I can to get the batteries topped up. The panels are ok if there is nothing else, they are not the answer to the future of energy supply. There is also the moral aspect of the feed in tariff. For the rich to load their electricity bill onto the less well off is not acceptable and those panels on the roof tell all your neighbors that you are doing it. That will show a greedy selfish attitude. If they are any good why don't the power companies buy them and save buying coal?

Q:where will i find solar panel info for free?
Hey Bandit, there are some really good websites on the subject, my favorites are operated by non profit groups, I will list them below. As the old saying goes, the best things in life are free, but there is one really good exception to that rule. Home Power Magazine is the only periodical that gets into the nuts and bolts of home grown energy. We started reading it 2 years ago. A couple years after that we attended an energy fair that was listed in the magazine, ended up buying our first solar panel and wind turbine on the spot, and hooking up a small 2 volt power system for our home that year. It worked really well, we did make some mistakes, but with the knowledge and experience we gained, we were able to get into a larger system a few years later. Now our home generates almost all its own power, and we use the utility company for backup. There is a .4 kw solar array on the garage roof, and a kw turbine on a metal tower in the field behind the house. We have also installed a batch solar water preheater and have 2 wood stoves for heat. Now our electric bills are around $6 per month. If your handy at all hooking up electrical devices, you could put together a small system like we did years ago and use it to run some small 2 volt lights and electronics. We still have our little system today, it operates the cabinet lighting in the kitchen, a few radios and phone answering machine, and we have 2 volt outlets in each room. They're handy for stuff like charging your cell phone with a car cord. I would suggest looking at the websites first, and if you're really interested, go for a one year subscription to Home Power. If you subscribe, you can even use their website to look at archived articles from years past. There is even one on our small system, the magazine liked the idea so much they wrote it up. Use their search engine to look for, Small System First. Hope you find all this interesting. Take care Bandit, Rudydoo
Q:How to connect solar panels to batteries?
20 volts is a common open-circuit voltage for nominal 2v panels. The panels put out about 5v at full load. If the panel puts out little enough that it takes 20 hours or more to put a full charge in the battery you can get by without a charge controller - just keep the cells topped up with distilled water. A charge controller will do a more efficient job, though. The most efficient charge controllers use what's called Maximum Power Point Technology (MPPT) which lets the panels operate at their most efficient point throughout the battery's charging cycle. Available on OKorder. The charge controller should have the same or higher wattage as the panels it controls - if you're not sure of wattage, assume that they are the same as similar area panels you find for sale. Before buying a charge controller, connect the panels through an ammeter to a discharged battery. They may have been trashed because of damage and low output. You need at least an amp for trickle charge, 5 amps for reasonable recharge times.
