Q:I want to buy a solar panel kit to run my central AC unit. it is a 3 ton unit. Can I do this? The electric rates in the Chicago area are skyrocketing and I can't keep paying 350 dollar electric bills during the spring and summer months

Solar in Chicago is not much help, you would need at least 3kwh for whatever size unit you have, (3 tons is meaningless in this context!) You would not get enough sun even in the summer to operate for more thn 6 hours a day. For Chicago you probably need a wind generator, or go for a heat pump.

Q:I riped two solar panels out of some solar light and tested them. I found out that they both produce 2 volts(I have no idea on the watts or amps). Iquot;ve hooked them up to an electric motor that can be driven by a AA battery, but when I hook the solar panels up to them nothing happens. What is wrong?

Mark G has a good answer. If you leave your voltmeter on the solar cells when you hook up the motor, you will see the voltage drop to near zero. Same thing would happen if you tried to use 2 9 volt batteries to start your car. They just cant maintain the voltage when high curent demands are made.

Q:Do solar panels require a battery backup system?

No, solar panels do not require a battery backup system, but it can be beneficial to have one for storing excess energy for use during cloudy days or at night.

Q:If I put a 5000 watt solar panel kit on my roof in Dublin (Ireland) - how much electricity would I realistically expect to get?An educated guess at a percentage of 5000w would do.

Do you want a time average? During the winter you will be lucky to average 800 watts daily Summer you could get 2000 watts

Q:I am looking to buy a solar panel.What does it mean when in the title it says 200 watts, or 50 watts?

Q:Is there a material that is capable of absorbing enough UV radiation to make it worth using as a flexible solar cell?Not flexible as in aluminum, but a material such as plastic (polycarbonate).

Q:I have a playstation PSP charger that is 5v 2A, so it takes 0 watts.I have several small solar panels that put out watt a piece and are 4 volts, 250mAhow can I get my 0 watts to be 5v 2A instead of 4v 250mA? the voltages have to match up right?also, what's a 3-T regulator that controls voltage?

The first item is whether the psp charger output is ac or dc. IF, AC then you are stuck as the panels put out DC. (Increasing the voltage enough to cover invertor losses is not practical in this instance!) IF DC, then you need to combine panels to produce 2 Amps, after which it is run through the 3 terminal VOLTAGE regulator to limit the voltage to 5v. That is 8 panels in parallel in 2 groups placed in series = 2amps at 8 volts, then add regulator for 2 amps at 5v. (Parallel increases amps, series increases volts.) Total panels required is 6 panels.

Q:What happens to solar panels during a power outage?

During a power outage, solar panels do not generate electricity as they rely on the grid for their functioning. This is because most solar panel systems are grid-tied, meaning they are designed to feed excess power back into the grid and draw power from the grid when needed. However, some off-grid solar systems equipped with battery storage can continue to operate during a power outage, providing electricity to the connected devices or storing excess energy for later use.

Q:Can solar panels be installed on a building with historical significance?

Yes, solar panels can be installed on a building with historical significance. However, it is important to consider the preservation of the building's architectural integrity. Careful planning and design are necessary to ensure that the installation of solar panels does not compromise the historical value of the building.

Q:Hi.How efficienent are solar panels? I mean, suppose we install a kw panel.. Wil it produce 5kw in 5 hours of good sun light?Or like if its 80 percent efficient, wil it produce 4kw and so on.Also, do the chinese solar panels give the same results as compared with panels from other countries?I live in india, so we get plenty of sunlight during the day.Thanks
