Q:solar panel installed house roof?
How does the cable wires stay on the solar panel? With wire retention clips (4 per module) that are used to wrap the wire on the underside of the module frame. The home run cables to the transition box (converts between types of wire with no electrical transformation occuring) or combiner box (joins multiple source circuits in parallel, with the positives fused for safety) are usually tied along the racking system components, and with conduit sections used as needed. Racking is another big part of the installation. Don't just make your own homemade wooden rack, as these will weather away to nothing very easily, and cause great failures. GET a professionally designed metal racking system. PV modules are EXPENSIVE. Don't let the racking system cause them to break. It also requires the inverter, if you intend it to connect to the main electric service. If using multiple inverters, you need an AC combining panelboard to join them prior to entering the main electric service. Otherwise, you need to think about how else you might be using them. If you are charging batteries, you need a charge controller.
Q:Building my own solar panels?
Hello, okorder.com. Look at some videos ( There are few hundred of them ) Basically though they all stay with the same idea or plan. Look at how they wire them and get more familiar with what they are running on them depending upon how much wattage panel they are running. I seen a 400 watt system costing about 600 dollars US currency. Because two 200 watt panels = 50.00 each and the diverter = 50 and the charge controller = another 50.00 at the least. Then you have wiring and some deep cycle 2 or 6 volt batteries to loop up which is extra cost if none laying around to use. Check-out youtube though for the best advice and opinion you can give yourself then maybe look at a few solar panel websites which sell Solar kits for some more price ideas. To run a laptop i assume you will need atleast 400 watts and 2 to 4 ,twelve volt batteries which are deep cycle and it might take 3 to 5 days to charge up your batteries but they should charge laptop battery no problem without much loss if you keep laptop charged often. TV is power hungry and you will need something like a $500.00 system for that. 000 watts etc. Tv just drains the battery bank way too fast. So to answer your question about what you can get for 200 bucks. Maybe a 80 watt kit system for about 250 bucks complete except batteries. with 80 watts you could power some cool nighttime night lighting with super bright LEDS or LED light strips which are about 0.3 watts per LED or 5 watt LED cabinet lights work well So for a 80 watt system you probably only want one 2 volt battery or else will take alot longer to charge on such low wattage. But you could run LED lighting for nighttime lighting and easily save 250 dollars in a year off your bill by charging phone from it, using LED lights and other low wattage devices if utilized daily. Just don't draw more power than it makes and it should be ok. Goodluck with your research.
Q:thermodynamic question that includes heating water with solar panels?
Good points. I'm new to the solar energy world, but solar just makes sense. Who wouldn't want to make it work? The more I learn the more I think its a great alternative to some of the energy we use. This info really helps.
Q:how fast does a 25watt solar panel generate power to a battery?
Small house needs at least 0000 watts at peak power. Therefore your need 80 pieces of 25 watts solar panels.
Q:Solar Panels in the 200 Toyota Prius?
The solar panel powers the fan in the solar-powered ventilation system. The ventilation system helps to keep your car cool while parked out in the sun. If your car is cooler, then when you get into it after parking somewhere the AC won't have to work quite so hard to get you comfy when you start your car. Less AC use means less hybrid battery use (since the hybrid battery powers the AC), which means that your gasoline engine will run less (to recharge the hybrid battery), meaning better fuel economy for you.
Q:Single Solar Panel savings?
No matter what or how you do it it is best to get off coal and nukes. So it cost a little bit of money you are buying 30 years of electric. How much will you spend adding in cost of living increases over the next 30 years? Solar really is pretty cheap if you take the time to do the long term math. If you use your cost at to days rates it does seem like a lot. But if you do the math like in real life with 3.5% compounded cost of living increases per year and 6.5% fuel increases per year. Well, you pay a lot more renting power. One other thing to think about and Al Gore keeps pointing it out is, Will your off spring be alive in 50 years from now if you don't buy the solar panel? Kind of like not going to the doctor because you can't afford the bill. Well I would rather owe a bill to a doctor that I will have trouble paying then not be alive at all to try. If you don't have the money to jump in and go full blown Green you should buy a starter system. You can get a system that can be expanded to 3000 watts (enough to power an energy efficient home). Would cost you about $8000 USD to get started and then you could add three solar modules at a time till you get it up to the 3000 watt max. And even have backup power. Or you could just buy a 000 watt system for about the same price and just add 3 of them over the years. There are many ways to get started. The deal is everyone needs to get started even if it is a small system. If all 50 million homes in the USA would install a small 000 watt system with 4 hours of sun light a day. We would provide (000 watts times 4 hours times 365 days times 50 million homes) 29,000,000,000,000 watts not from coal or nuke plants per year. I wonder if that would help?
Q:What things can a solar panel power?
With the right equipment anything that requires electricity. I have been living on solar power for 6 years now.
Q:solar panel roofing?
The solar panels are very expensive to provide much power. If u go that way do not skimp on the support as a high wind will blow them away. In Ecuador I put in a remote site for communications. It was working good when a Strong wind blew $0.000 worth of solar panels all over the jungle.
Q:Chem question regarding using solar panels ....?
It is not that simple. There are 3 main types of solar cells. Monocrystalline silicon is the most efficient and produces the smallest solar cells, and therefore the smallest panels. Poly-crystalline (or multi-crystalline) silicon produces the next most efficient type of cells and are a popular choice. Amorphous (or thin-film) silicon uses the least amount of silicon and also produces the least efficient solar cells. This means thin film system take up more area than the other two; an important factor to consider in relation to possible future upgrades; i.e. if you'll have enough space left to do so. The North (in the Southern hemisphere) or South (in the Northern hemisphere) facing roof collects the most energy. So this biases the roof area required. Your energy usage can be changed. Hot water (a major energy user) could be better using direct solar heating with peak demand boosting, either from mains or solar. There are other possibilities, either to reduce demand or to provide energy from other sources. Not all sunshine hours are equal. Hours around midday are far more productive than hours later in the day. This must be factored in.
Q:what do we mean by efficiency of a solar panel?
Photo-voltaic solar cells use the visible light range (photons) for the conversion of sun's rays to electrical energy. The potential of solar radiation is ,353 Watts per square meter, but that is mostly a measure of heat, or infrared radiation. The visible light is actually a small portion of the spectrum. You have struck on a problem associated with photo-voltaic cells. Infrared radiation acts to heat up p-v cells (heat stress), causing them to be much less efficient. It would be interesting to see a hybrid p-v panel that is cooled with fluid or air running through it. This would increase efficiency of the p-v process while providing a heating source. This in turn could be used directly for heating or for production of electricity through a generator system.
