Q:Are solar panels efficiency already calculated in their power rate?
Solar panels are tested in a lab that has a light the produces 000 watt/hrs per square meter. In these conditions your panel will produce 80 watt/hrs. If you would like to know what it does in really world conditions you have to find the sun-hours in your given area. A sun-hour is basically how many watt/hrs hit a square meter in a day. This number changes based on time of year, orientation, and temperature. Here in Fairbanks Alaska if the panel was at 90 degrees facing true south in October (.9 sun-hours) It would produce 80 X .9 X .8 (20% efficiency loss due to wires and controllers) it would produce 273.6 watt/hrs on average each day.
Q:solar panel??????????????
The only real purpose of solar panels these days is to charge batteries - they just don't generate enough energy to do anything else and its dependent upon light levels - ergo you need the backup. Also - very expensive.
Q:Power Point on solar panels?
Energy conservation Use sensors that turn of lights and unneccassary equipment when person leaves the premises 2) Saves hard earned energy 3) Area of roof space depends on how much energy you want to collect from the sun.
Q:How much should a 00 watt solar panel cost?
On OKorder, they seem to be priced around $400. You do realize it takes more than just the panels...
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:How much do solar energy panels cost?
I co own Sunpower Solutions. We are a solar company in South Jersey. I can tell you that the average cost for a system under 7Kw, is $7.95 per watt. What people fail to realize, is that there is a lot more that goes into a PV system than just panels. Racking, hardware, combiner box, inverters, labor to put the panels up, pay the electrician that ties it all together, the architect that measures the wind load on the panels, etc. It's not cheap. Although, in the state of NJ, the the amount of time it takes for the system paying for itself, is 4 years. It doesn't matter if it's a huge system or the smallest PV system, it's 4 years. Any questions, just ask. @Martin: The thing with those programs, is that the company that is leasing the system, is taking advantage of the renewable energy credit that the system is producing. Yes you get cheap electricity, but you are not taking advantage of the money making ability of the renewable energy credits.
Q:Can you tie small-scale solar panel system into household electrical system?
You can't directly connect solar panel into household electrical system,you need to convert DC power to AC power more over it will cost more amount...
Q:How do you make a solar panel?
Did okorder.com . This is able to extremely manage one and all!
Q:Should we subsidize solar panels?
Recent investments into solar panels have brought about a couple of interesting realizations and developments. One, as you state, is that traditional solar panels (silicon crystalline panels) are not currently cost effective, even will full-scale manufacturing production. It's possible that improved manufacturing techniques will bring the retail price down somewhat, but it needs to be brought down a lot to make economic sense without incentives. The other, though, is that a new method of producing solar panels - thin film technologies - has been developed. These are currently quite expensive, but because there are no crystals to grow, they are expected to drop significantly in price as production increases. I believe that this technological development has been made as a direct result of government support for solar energy. It is not taking money away from research - rather it is providing the incentive for research. I could be wrong. I've been wrong before. But I think that these new solar technologies, which are already hitting the market, will dramatically change the economics of solar energy.
Q:Solar panels for car fans?
The solar panel doesn't output enough power to run the fan directly, your best bet would be to just hook the fan back up to the battery, and then rig the solar panels up to help charge the battery and remove some of the load from the alternator. If you're trying to reduce your emissions/increase fuel economy then you'd be better of setting up a switch to disconnect your alternator when its not necessary to have it on. The alternator runs off a belt from the engine which requires some of the power output from the engine. Having this connected all the time increases the amount of gas used (marginally) but you'd be saving more gas doing that and using the solar panels to keep the battery topped up.
