Q:SunPower Solar Panels?
Power from solar panels depends upon its proper installation and the brightness of the Sun.
Q:what kind of rays are used in solar panels?
Electromagnetic...meaning light rays, primarily in the visible spectrum. Ultraviolet and infrared light rays actually degrade most types of solar panels, limiting their useful lifetime. That said, your question is not stated well...so I'm not sure if that's the information you were looking for. Rays are not used in solar panels...rather solar panels are used to collect sunlight and convert it to energy--either directly into heat in the case of passive solar, or into electricity by the use of photovoltaic cells.
Q:Solar Panels question?
maybe you ought to ask a solar installer in your area. who knows what the electric rates are. and how much electricity you use. and how much sun there is. and what your electric utility's policy is. and what kind of house you have, and how you use electricity. and what appliances (eg stove) you might convert to electric to take advantage of solar panels. wouldn't that seem to be a good idea?
Q:Pls is it ok to connect a 0watt and 20watt solar panel together into a charge controller port?
Tobi, generally yes, solar panels are like beer, all the europeans get along fine, you can put two Belgiums in the same room as one German and three Englishman. As long as the panels have roughly the same open circuit voltage, usually around 8 volts, then go for it. If you're not sure about this, or the panels voltage disagrees dramatically, then they can still work through the same charge controller, the only other thing you need is a bypass diode in the junction box on the back of each panel. Most modern panels come with these already installed. They are simply electrical check valves, allowing current flow in one direction but not the other. The reason these matter is when the sun is first coming up, the higher voltage panel can force its power backwards through the lower voltage panel, at least until they both reach a voltage higher than the charge controller is set at. This is not a desirable thing to have happen, the 20 watt panel, if its voltage is higher, can damage the 0 watt panel without these diodes if the 20 watt has a much higher open circuit voltage, or Vmax. Look on the back of the panel for these ratings. The only other concern is maximum current. A charge controller has a maximum current it can handle, they are generally model numbered this way, a Xantrex C-60 for example has a 60 amp rating. Add up the Imax numbers on the back of all your panels, this is the maximum amperage the panel should put out. As long as it is not above 80% of your charger controllers maximum amperage, your good. Take care, Rudydoo
Q:who would win in this battle?
hmmmmm trees would squash em and solar pannels would electric cute em............... :)
Q:Solar panel question
The answer is actually quite complicated, but if you're planning on building just a very small system, most likely, the panel will be small and weak. In this case, connecting a panel that is 8 volts open circuit directly to a lead-acid battery is probably the most efficient way to charge. There are charge controllers that you can buy, some of which actively track the maximum power point for charging your battery. Unfortunately, those controllers might eat 5 or 0 watts, just to get you another few percent of charging efficiency. If your panel is only 50 watts in the first place, you can see that this is not a good deal. If you're getting serious panels (clue: price $500 each), then you may very well benefit from a charge controller with MPPT (max power point tracking). Lead-acid, either a flooded cell like your car battery, or AGM, are the standard for solar energy storage. Lithium ion is better in many ways, being less sensitive to temperature, state of discharge, and they are also lighter. Charging them is also more straightforward with the right circuitry. The problem is, they cost like $500 per kWh, compared with less than a tenth that price for lead-acid.
Q:How do I get a grant passed for my school for solar panels?
Excessively long payback schemes for solar panels are being quoted. It depends on where you live, where you situate your solar panels, what you buy and if you get a grant or install them yourself. Much of the cost of Solar panels is in the installation. Any competent DIY person can install a simple solar panel system. Ours cost less than £000 to buy and self install. What are you calling payback time? Because each time I don't use fossil fuels and use solar energy instead, I don't get a 'fossil fuel' bill. Whilst we still use some electricity for running a fridge, lighting etc we have no other fuel bills, no gas, no oil, no electric heating no electrically heated hot water. We have woodburning stoves (which run on free wood) and solar. Remember you are not just paying for the electricity/gas/oil etc that you use, you are also paying standing charges, VAT etc. Include those in your 'payback time figures' and you will see a very different picture. How long would it take you to pay back £,000 if you only had one tiny electric bill each quarter?
Q:Benefits of Solar Panels?
There's a few different kinds of solar panels. Some of them are only for collecting heat, they're relatively inexpensive and not a bad deal, though installation can be expensive of course. The most sophisticated of these use some pretty high tech collectors to heat up an antifreeze solution that in turn is circulated through a reservoir (how water heater), to supply the house. Your electric producing solar panels are more expensive. You can go on OKorder and do a search on photovoltaic panels and get a pretty good idea real quick. The panels alone can run you 2 or 3 bucks a watt of output or more, and you may need 3 or 4 thousand watts of output to give you reasonable system for your house, depending on how much electricity you use. Then there's installation, for which you may need a professional electrician and so on. If you want a system incorporating deep cycle batteries then that's another expense, but you don't necessarily need those if you're not planning to take yourself completely off the grid. Not that the systems are really complicated. Some people wire panels together themselves from scrap cell components to save money. Of course you'd need to understand the basic wiring involved for that, and you'd almost certainly be required to retain an electrician to tie any system into the grid itself. Although there is such a thing as a plug in grid tie inverter. This is is a gadget that will take your DC solar panel output and feed it into the standard wiring of your house via an ordinary electrical outlet. You'd still need to understand enough to get the DC voltage right no doubt.
Q:solar panel??????????????
You okorder.com Basically, I wanted to do the same as you but didn't know how. I found this book and it showed me exactly how to do it and for a cheap price too! It's a good guide if you want to save a bunch of money on electricity bills. I highly recommend it.
Q:How do you connect a solar panel to a motor from an RC car?
can increase your voltage from a single solar panel. In combination with a large capacitor, you could deliver short bursts of power to the motor which would allow intermittent operation.
