Q:Buying inverter for a solar panel?
I'm guessing that each of those solar cells is just 0.5 volt at max power, so if you make a 2-inch square panel, you will get 2 volts - not enough for the inverter. A car inverter is notoriously inefficient, but it would work if you connect it to a 2-volt battery. You cannot generally connect such an inverter to solar panels alone. The battery supplies the peak current that the inverter needs, and the panel charges the battery. To charge a 2-volt battery, you will want 36 cells, generally, which give you an 8-volt panel. You can buy an inexpensive charge controller somewhere. If your laptop will run off 2 volts directly, you can skip the inverter and be much more efficient. Or if the laptop runs of (say) 9 volts, you can use about 40 cells to get 20 volts, get the proper power plug from Radio Shack, and plug the panel directly into the laptop.
Q:Reasons for installing solar panels in a school?
Cuts Costs over time
Q:Solar Panel - Battery Charger 2V?
How many amps will you need? Remember v x a = power. The way those trickle chargers work is by sacrificing some amperage to get up to 2 volts. If you can invent closer to ~3V range that solar cells naturally produce thing will likely work better. A sign or a light that doesn't need a lot of power will work. Automobile battery packs might take a month to charge. Solar-Powered 2V Trickle Chargers are used mostly to keep things like boat batteries in storage from discharging, not to charge them.
Q:It's all about Solar Panels?
A 35 Watt Solar Panel cost between 400 and 500 depending on where you make the deal. I live full time in an RV and I get all my electric from the Sun. I am sold on solar but I move around to places, according to the season, where I will have full sun most of the time. I also have a small generator as a back up but rarely use it. The amount of direct sun and angle of the panels will determine how efficient they are. For some one living in an apartment with only a few hours of sun then solar would not be good for them.
Q:How Can I Reduce A Solar Panels Output To 3volts From 9volts?
Solar panels generate DC power. Changing DC voltage is hard, which is why the power grid is AC voltage. AC voltage can easily be changed with a transformer. To keep the DC power (watts) the same at a lower voltage you need a DC to DC converter. That basically changes the power to AC with an inverter, changes the AC voltage to the new value, then rectifies it back to DC. It is probably hard to find a commercial unit that handles those voltages and then it will be expensive. But I have a simple solution in the special case of a solar panel. Solar panels are made up of smaller solar cells. The basic solar cell has a very low voltage, like half a volt. The panel has many of them connected in series to make a higher voltage. Just cover (shade) some of them and the voltage generated by the panel will be less. Of course that reduces the power. And you may need to experiment with shading different parts of the panel and measuring the result with volt meter.
Q:will a 5v 52watt solar panel charge four 2c dv 55ah batteries?
Technically, any solar panel can charge any battery, but it would take quite a long time do do so if it is a large battery. If you are aware of the voltage and either amp or watt rating of the unit that is usually used to charge the battery, the solar panel should have a similar power output to that charger to work well. amps and watts are quite similar, and can be converted with this simple formula: W=watts; V=volts; A=amps; W/V=A; V*A=W; When charging batteries, it is always wise to use less amps than needed, and roughly the same voltage as the battery being charged. The less amps used to charge batteries means the battery will take longer to charge but will last a lot longer in the long-term. Your solar panel should be sufficient to charge the battery, but you should test charge it to see if it works well. I recommend using a multimeter to check the batteries voltage every couple of hours. Once the battery reaches 2v, it should be fully charged. You should also check the amps in case they are not at the expected value (take caution when checking amps with a multimeter, when i do it i always end up melting my multimeter leads). The battery should be fully charged from anywhere between 6-48 hours. if it is charging faster, the solar panel has too much power. if it doesn't charge in this time frame, the solar panel is not powerful enough.
Q:Where can I get damaged solar panels?
Check out home power magazine for the list of vender's. Construction companies typically return damaged panels to the distributor or manufacturer for credit. The companies may have an inventory of goods for sale. Also, check out large insurance companies (Nationwide) to see what they do with panels they write off as catastrophic loss when a homeowner or business files a claim. Hope this helps
Q:Can solar panels be connected directly to motor?
The sun is irradiated on the semiconductor p-n junction to form a new hole-electron pair. Under the action of the p-n junction electric field, the holes flow from the n region to the p region. The electrons flow from the p region to the n region, and the current is formed after the circuit is turned on.
Q:Choosing right wattage solar panel?
Will a 30 watt panel at 2 volts be enough to run this system during sunlight and charge the battery for the equipment to run overnight? Maybe theoretically, but you're going to have very little margin for losses and clouds. I'll bet it has very little power when cloudy. 7.9/30 = 0.26. So at 00% efficiency, you'd need it to be charging more than 25% of each 24 hour period. In a summer with long days and a climate with few clouds, you might make it. But I think you're very close to the edge. And, at 55 AH, how long can I keep a constant draw of 7.9 watts without a recharge? For an ideal battery: time = Q V / P time = 55 A h * 2V / 7.9W time = 83 hours So you've got pretty good margin on your battery.
