Q:can i make a solar panel out of aluminum foil?
No but look in youtube for other ways of charging batteries . There is allot of neat ideas like building a small wind generator from scrap parts such as old speaker magnets copper wire out of transformers things that most people toss in the junk .
Q:How much was the price of solar panels 5 years ago compared to now?
I to register for free and lock in long term costs. The increasing demand and competition is helping reduce costs.
Q:Is anyone using small solar panels in their home with any practical results?
Q:How do solar panel power systems work?
There are two kinds of solar panel power systems, one is on-grid solar power system, the other is off-grid solar power system. The on-grid solar power system: the solar panel convert sunlight into DC electric, and the DC electric is converted into AC electric by inverter, one part supply for the household load, the other supply to power grid. The off-grid solar power system: the solar panel convert sunlight into DC electric, and charge for the battery or supply for the DC load by controller, if have AC load, it need a inverter to convert DC into DC.
Q:Wiring in solar panels?
I am all for do-it yourselfers, I am one, but... Sorry to tell you, but connecting solar panels to grid power will require an electrician. There are many requirements for special disconnects to prevent harm to the utillity company workers that must be considered. You will also have to have an inverter sized to match your panels. The simple answer is to connect your panels to something specific, without connecting it into your house wiring. An example is to connect your water well pump to solar power and disconnect it from the grid. But you will still need an inverter and will need to calculate the power demands of the pump and the amount of power available from your panels, which varies by your longitude and latitude. It sound like a simple thing to do, but without special training and experience you will be sorry if you try this yourself.
Q:Who will remove solar panels?
Q:Im looking at getting solar panels.
Solar panels are very expensive and take many years to pay for themselves. You'd be better off contacting your congressmen to lift bans on Nuclear and other producers of electricity. That would lower the costs and save much more than the hassle of hooking up solar power and batteries etc.
Q:Solar panel question..?
Little solar panels on lights are very low power. The battery in one such may be 0.5 Amp-hours and .2 V ; it may be different but it should be marked on the panel/battery/manual. An outlet in your house is designed to run on 20 V (typically in N. Am.) and they run on alternating current (AC) whereas the panel generates direct current (DC). (If you don't know the difference, do not worry to much but just understand that they are not directly compatible.) You therefore need an inverter to change DC to AC (and lose some although inverters are now very efficient). But the amount of power generated by those panels is still very small. That is why solar lights are low power (just a few watts in most cases). To make things even more irritating, phone chargers do not work off 20 V AC as you are charging the battery and need a low voltage DC -- which is what the solar panel is giving you. It is almost certain that the voltage from the panel will be less than the voltage required for the phone. The charger is mostly cable but there is a black box incorporated and it should say what the voltage and current output are (the input will be 20V). So you should be able to overcome this not by hooking up the panel to a 20V outlet and then plugging the charger in but by hooking up the panel to the phone directly if you can get enough voltage out of the solar panel (or hook up several) and if you fashion a connection device. They already make them -- solar battery chargers and I am sure you can enter that into a search engine and find loads. Typically the panel alone is much more than a solar light -- which shows the relative power requirements.
Q:What is so great about solar panels ?
Solar panels saves energy (electricity) because the power comes straight from the sun and stuff
Q:Solar panel connectionI
The answer is that the two panels should be put in parallel. The voltage out will drop to the voltage of the lower panel, but you should get most of the power, if the panels aren't too badly mismatched. I would try to get a multimeter and try to measure the actual current coming out of the panels in full sun. Sometimes the specifications on these smaller panels are very optimistic. If the whole setup is putting out less than 2 amps, I'd say wire the whole thing straight to the battery - little chance of boiling the electrolyte at those currents.
