Q: For my Product Design Coursework I am designing an environment friendly building according to a clients' specifications. I need to find out the dimensions of 0000 watt solar panels. any help would be much appreciated!: About 2500 Sq. Yd.s

Q: I have seen DIY software which explains everything for novices. Specifically, how to build your own solar panels and tie them into your home electrical system for about $00 in parts.Has anyone tried doing this? Was it easy?: Your location could effect this answer significantly.If you are in an area that requires considerable amounts of heating,and you are looking to save some money with a homemade project,try solar-thermal.S-T is easy and cheap ,can be built from common scrapyard materials,and will give you a great knowledge gateway . The orientation and tracking skills you will learn can be used later with PVs if you choose,or you can make better concentrators for the solar-thermal and build yourself a sterling or rankin cycle engine to generate electricity.If u need heat,or even hot water, u can start saving the money u put into the system immediately. Concentrated PV is here and now ,but, in a year or 2 it will be cheap and readily available and thats when PV will start to approach the efficiency of solar-thermal.there a great sites and groups on just S-T out there ,join 'em,check 'em out,read the free info from those who have built working systems,and you will probably find a more useful method of saving money and the planet at the same time.Just remember to approach it as a hobby/learning experience at first.Start with solar-thermal....theres a reason the anti-greenies point at the ROIs on PVs,great arguement against alt energy,but over the last 30 years I've shut up quite a few skeptics with my solar-thermal projects ,esp. when coupled with geothermal...have fun,make a local scrapyard owner/worker ur freind..................GEOD

Q: Can solar panels be installed on flat surfaces?: Yes, solar panels can be installed on flat surfaces. However, it is more common to install them on angled surfaces such as rooftops or mounting structures to maximize their efficiency and exposure to sunlight.

Q: I thought they were going to make solar powered cars and solar power plants among other things. It was only nearly 0 years ago that solar power was the big thing. Just curious, why did it die out?: they still make them,i have them on my camper to charge the batteries, they are not cheap, however. you can get them at r.v. supply stores. in fact the ones they make now, are quite efficient, many people in the countryside use them for their homes, i dont know why the development for cars is so slow, though.

Q: Can solar panels be installed on agricultural irrigation systems?: Yes, solar panels can be installed on agricultural irrigation systems. They can provide a sustainable and efficient source of energy to power the irrigation system, reducing reliance on traditional electricity sources and reducing operational costs for farmers. Additionally, solar panels can help farmers become more environmentally friendly by reducing carbon emissions associated with irrigation.

Q: Can solar panels be installed on windows or glass surfaces?: Yes, solar panels can be installed on windows or glass surfaces. There are specialized solar panels designed specifically for this purpose, known as transparent solar panels or solar windows. These panels are designed to allow light to pass through while still generating electricity.

Q: can solar panels be on houses? malls?stores? WHAT ABOUT TRAINS?: Solar Panels can be used anyway were the panels can get sunlight. Increase efficiency facing north in Australia. You can place them on a roof of a building, caravan, boat, train, bus etc plus you can put them on stands on the ground. Great for camping. You can connect them to the electricity grid or use standalone systems to generate all the power you need. Germany is the leader in solar power usage and Australia gets more sun then they do It makes sense that all Australian households should use solar.

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?: 325 mAh+ losses so maybe 3.2Ah to 3.5Ah.

Q: I'm trying to charge rechargeable AA batteries with a solar panel. What gauge wire should I use to connect the panel to the batteries? I know I'm not going to have a lot of current going through so the wire size doesn't really matter. Can the wire be too thick thoShould I ugh? Should I use a diode to keep the batteries from overpowering the circuit? If so, what size diode? My panel is 4.8V 50mA. Can I just hook the panel straight into the batteries or do I need something else?: In order: .? Just about any wire will do.? You can handle 50 mA over just about anything, even 28 gauge telephone wire.? Your biggest problems are probably going to be mechanical stress (you want stranded wire instead of solid, to avoid breakage) and dealing with the size of larger wires. 8 gauge speaker wire may be a good optimum. 2.? You need a diode.? If you're charging NiMH or NiCd cells you're going to have about .25 volts/cell; you can charge up to 3 of them in series with a 4.8 volt panel.? The solar panel is a bunch of diodes itself, but they're leaky in the reverse direction; the diode prevents the batteries from discharging themselves back through the panel.? You want a Schottky-barrier diode, because the forward voltage drop is about 0.2 volts instead of 0.7 volts for a regular silicon rectifier.? This gives you maximum current output from your panel.

Q: Can solar panels be installed on a pergola or awning?: Yes, solar panels can be installed on a pergola or awning. In fact, these structures can provide an ideal platform for solar panel installation, as they offer ample sunlight exposure and an elevated position that maximizes energy production. Installing solar panels on a pergola or awning can not only generate clean and renewable energy but also provide shade and protection from the elements.
