Q:Currently being sold today! I know SunPower corp. commercial panels are about 20%.: New rollable panels are becoming available that don't have to be permanently attached to a surface and that are more resistant to damage than conventional panels. Right now they are also even less efficient than photo cells at about 0%, but the cost factor may make up the difference. Solar thermal is more efficient than photovoltaic cells. They focus sunlight with mirrors onto a pipe containing a liquid which is then heated to it's boiling point. That turns a turbine to produce power or is harnessed in some other way. The panels are cheap compared to photo cells, don't require perfect manufacture or exotic materials, no expensive maintenance and they are much easier to repair. I don't know of any available to individuals yet but there are at least two companies building generating plants in Nevada with this technology. SunPower is about 22% efficient but even at that rate it will take decades to pay for itself and the panels are unlikely to last that long at anything near optimal efficiency. The cost is just too high at present but solar thermal may provide a good alternative until photovoltaic cells mature, if you can cobble together a system. The final link is about a claimed 80% efficient solar cell that even generates some power at night. It's based on nano-technology, like many promising energy developments in batteries, electrolysis and ethanol production. If it works as advertised it should revolutionize solar tech. Eventually.

Q:I was thinking of having some installed on our rooftop and was wondering if it would be worth the cost? The house is located in Sac, Cali. The panels would face the sun 2 months out of the year and in the summer roughly 4 hours of straight sun.: You can log in alibaba,i purchased about 20000watts 2 years ago and solar panels work efficiency is fairly high. I hope my answer help you !

Q:what size would the panel be/ I live in the caribbean so plenty of sun!: What does the advertisement have to do with your question? Yes; BUT, depending on the pump, you may need several panels and possibly an inverter if it is an AC pump. You will ALSO need at least battery in the circuit to provide a load to the panel.

Q:I'm building a solar panel for the first time and have the tabbed solar cells. I put together 4 strings of 9 cells. And the cells are each 0.55V, 3.6A.Because I'm going to be using the panel indoors and leaning it up against a window pane, I put them in a 24x36 inch poster-size frame. The frame has a plexiglass cover and a thick cardboard backing. My question to you is this. Will the cardboard backing up against the metal underside (positive side) of the solar cells be ok? I don't know if it may catch fire or if holes may burn through when there's full sun.My guess here is it should be ok. But maybe I'm wrong. If I am wrong, or if something should be put in between, please let me know what I should use.Thanks everyone!: In commercial panels some sort of polymer is often used for backing. With a 2V panel there are 36 cells, which means they can still output about 4V for charging a 2V battery even when hot. The voltage reduces about 2.2mV per degree C per cell. Commercial panels are meant to work up to about 60 degrees C, which is quite normal in the sun. I have found just lying them on the grass the air circulation is reduced, and they get too hot to charge a 2V battery. This means the backing should have good thermal conductivity while being an electrical insulator, as well as mechanical strength. The cells are often encapsulated in a thermosetting plastic first, then laid face down so a liquid polymer can be poured as backing.. I have removed commercial panels from their frames and re-packaged them to work in a very wet environment. I suppose cardboard would work, but it is unlikely to have good cooling so the expected voltage would be lower. As you intend to only operate indoors I suppose it is unlikely you have full sun most of the time anyway, so there could be less heating and less output current accordingly. I think the cardboard is only useful for a short time, and is not strong enough. Temperature wise it is marginal. The link below uses plywood for the backing. The backing is supposed to provide strength too. A sheet of some sort of plastic or laminate (including melamine laminate as in kitchen bench tops) comes to mind too. The cells are supposed to be bonded to the backing for better thermal conductivity. Use silicon RTV to stick cells to the backing, very thinly.

Q:Can solar panels be installed on government buildings?: Yes, solar panels can be installed on government buildings. In fact, many governments around the world are actively promoting the adoption of renewable energy sources, including solar power, in their buildings to reduce carbon emissions and promote sustainability. Installing solar panels on government buildings not only helps in reducing energy costs but also sets an example for the public and encourages wider adoption of renewable energy.

Q:I'm trying to charge rechargeable AA batteries with a solar panel. What guage wire should I use to connect the panel to the batteries? Should I use a diode to keep the batteries from overpowering the circuit? If so, what size? My panel is 4.8V 50mA.: With that size panel, you should be able to recharge either AA battery, or two AA batteries in series. Yes, it would be a good idea to put a blocking diode in series with the panel - anything will do, like a N448. You will want to use NiCd batteries if possible, because they take a trickle charge of 50 mA much better than NiMH (which prefers pulse charging, a more complicated circuit). You can use NiMH if you must. Needless to say, don't try to charge non-rechargable batteries. Also realize that at this charge rate, it will take days, maybe even a week, to charge the batteries, if left out in full sun all day long.

Q:I have just made my first dolar panel 20 watts, charges my 27TMX Trojan battery perfectly. Now I am thinking to build more solar panels for a grid tie installation at my house, maybe 5 panels would do it, is this safe?: Congratulations on your solar panel. It takes a lot of work to construct one. Tying to the electric grid requires permission from your power company, and conformance to local building codes. This generally means compliance with the National Electrical Code (NEC), meaning your panels must be UL (or similar rating from another standard) listed, for fire and electrical safety reasons. Homemade panels won't qualify, unfortunately. I really would discourage you from trying to do a jungle installation without permission, as the power distribution in a house is nothing to be trifled with. That would also likely void your homeowner's insurance, and give the bank a reason to call your mortgage, if you have these.

Q:How much electricity does a solar panel produce?: The amount of electricity a solar panel produces depends on several factors, including the size of the panel, its efficiency, the amount of sunlight it receives, and its location. On average, a standard residential solar panel can produce anywhere from 250 to 400 watts of electricity per hour under optimal conditions.

Q:Can solar panels be installed on camping sites?: Yes, solar panels can be installed on camping sites. They are a great renewable energy option for powering small electronic devices, lighting, and charging batteries while camping.

Q:I'm curious to know if the small solar panels on a calculator (ie TI-32) could produce a voltage similar to what is used in a single-use (disposable) camera, approximately 4V.: It isn't Volts that matter if you're trying to put the calculator solar panel on the camera. It would be the amps. The calculator's solar panel will put out however many volts or very close to what the battery puts out. If you want you can test it out with a Volt/Ammeter. You see, those cameras use 2 double A batteries. They are going to put out a higher current than the small dime shaped battery in the back of your calculator; a higher voltage perhaps too. Those disposable cameras have a photo flash capacitor in them that has to charge. You can hear them charge up when you tell it to turn on the camera's flash. Sounds like a winding then the little orange light comes on. That light means the capacitor is charged. You SHOULDN'T be able to change out the batteries in the camera with a solar panel from a calculator without having to wait days for that flash capacitor to charge. Sorry. EDIT: HOWEVER, you can take multiple solar panels and wire them in a parallel circuit to get more current(amperes) or wire them in a series circuit to get a higher voltage. If you were to do this you could power whatever you wanted with them. Even your house if you were to get a rectifier to convert the power from DC to AC.
