Q:How to find amp for solar panel project?
It is possible your meter does not have the capacity to safely measure more than 300 milliamps which is too small to measure current output from solar panels. Assuming no losses in the system or components, if your meter does not have the capacity to measure 0 Amps, you will need to get one that does. Analogs are better than digitial for this. Most often the 0 Amp circuit of the meter has a discrete positive plug location for the positive test lead. Most have a common ground connection with the rest of the meter functions. If you are measuring current at the battery in the charge mode- Negative lead of meter goes to positive terminal of battery and positive lead of meter goes to the cable that was connected to the positive terminal of the battery. Since the Wattage is a nominal measurement, if you measure between the panel and controller, take measurement on one leg of the panel, as you want to measure the current with the loaded active circuit. Meter is oriented the same way as the measurement at the battery would be made above only this time the meter is between the panel and controller. At peak solar conditions, expect current to be measured at 2.5 to3 Amps or more per panel. Under optimal conditions your panel will have higher output than their ratings indicate. Open circuit can be close to 20 volts. Never short circuit the output of the solar panels. It is volts multiplied by amps that gives you Watts.
Q:What is the difference between solar panels and light panels?
Crystalline silicon cell conversion rate, rich in raw materials, is a large-scale commercial production of the battery, but the crystal silicon battery brings the harm can not be ignored. Crystal silicon series of batteries have a "three high more than a" common problem. High cost, high energy consumption, high pollution, byproducts and other shortcomings.
Q:List of new solar panel manufactures?
There okorder.com/
Q:Cost of a solar panel?
That's more like a bare laminate, and will not be durable, but will get you a legitimate $/watt. Also understand that if a manufacturer has a cost of $/watt, that means the panel will cost more by the time you buy it. It has to be shipped, stocked somewhere, and the retailer has to make a profit. $560 is high for a 20-watt panel today. Whoever is selling at that price will not sell many, or will sell only to those who aren't shopping around.
Q:A couple questions about home made solar panels?
there are plenty of free sites that tell you how to install your own solar panels. Just google diy solar panels. as to how many panels you need, it depends on what all you're trying to have them run.
Q:how to power a 400 watt heater with solar panels and batteries?
well, you need to produce 3200 watt-hours per day with your solar panels how many you need depends on the type of panel and size and how much sun you get (the energy of the rays depends on your latitude and the time of year) the amount of batteries you need again depends on your requirements and your insolation if you only need to heat when the sun is shining then you don't need any batteries at all if you want to heat for 8 hours after the sun has quit shining then you obviously need batteries to hold 3200 watt-hrs of electricity to actually size a 3200+ watt-hr solar system you need a lot more information
Q:Is getting solar panels worth it for your home?
It depends upon how you look at things. If you are looking for a decent return on investment, or a business decision, it is probably very unwise. In most cases people would see a far better return in upgrading insulation in ceilings, walls, and windows to much better insulation than they currently have, followed by proper resizing heating and air conditioning to smaller unit size to fit their lesser need as a result of the insulation. The heat an air conditioning units should be the highest efficiency available. The return on the above can make a positive and economic investment in many cases. If you have done the above first, and have money to spend and do not care about the return on it, then you can play with solar or wind. However, typical cost of generation of solar and wind energy is about $0.22 / KWH and you can purchase from utility at about $0.0/ KWH including generation and distribution so this is not all that prudent.
Q:Will a 3w Solar Panel Charge A 55ah Car Battery?
Quite a while. I am assuming you are using 2 volts as your buss power. The small panels were intended as a float charge for batteries to keep them from discharging over a period of time. 3 Watts means only /4 Amp. Normally when I do slow charging of batteries, I am using right around amp, and that takes about a week to bring up a battery that was discharged past 80 percent capacity. When you factor in losses from corrosion, battery self discharge, and loose connections, you will likely want to add more panels. using your 55Amp/hour battery, a amp charger running constant in a perfect world would take 55 hours. Real world, probably closer to 64 to 72 hours. That for simplicity is 5 Watts constant charge power. Now you are using /5 of that with your current setup. so 5 times longer, whichh puts you in the 300 hour range of real world, or 220 hours of perfect world. This time of year, you may have about 8 hours worth of charging light, which puts you at close to a month. Don't fret. If you are using it for lighting in a shed, Power LEDs and tethering some of the inexpensive LED lights to the 2 volt source will give you plenty of light for a very long time, the panels will help some, but you will likely need to put the batteries on a charger, or you can build a gas powered 2 volt generator easily enough. Charge it up only when needed.
Q:Can I join 5 or more solar panels into line to the battery bank. I don,t have a regulator connected, just st?
Two things on a regulator: a) It will optimize the charge to the batteries - and thereby distribute the most possible power to your active circuits during the day. b) It will prevent the power from the panels from boiling (no kidding) the batteries - no small thing as they are the second largest investment you have after the panels themselves. This is much more critical if you have sealed or Zero-Maintenance batteries. I strongly suggest that you get a regulator as it will significantly lengthen battery life. Follow the directions on the regulator for optimum input voltage and it will let you know whether all the panels should be in series, parallel or series/parallel. But cutting to the chase, you can certainly gang up panels as needed.
Q:What are solar cells made of?
A okorder.com/, or resistance—vary when light is incident upon it) which, when exposed to light, can generate and support an electric current without being attached to any external voltage source, but do require an external load for power consumption.
