Q:I have a solar panel that puts out 00v, .5 amps in full sun. Before I thought it would charge a 2v battery without a solar charger but then I talked to someone and they said that it was wasting a lot of power and could potentially hurt the battery. A second part to this question is what happens if I put it on a 72v battery without a controller. Thanks!: The solar panel is capable of /2 Amp output. If you hook it to a 2V battery directly and the battery is discharged it will want more than /2 Amp and pull the voltage down until the battery is charged to a certain level. Eventually the battery will try to charge up to 00V which will definitely damage the battery. If you use a regulator circuit running off the solar panel that outputs 2V then you will have a constant voltage circuit which will still be limited to /2A or whatever the regulator is capable of outputting. Of course you can't just go out and connect 00V to any voltage regulator it has to be capable of running from 00V and dropping the voltage to 2V like the original charger that comes with the battery. The same explanation applies to a 72V battery. You have to limit the output voltage to 72V or risk overcharging the battery.

Q:i need to make a solar panel model for a project in science and i would like to know how to build a easy model at home that wont cost alot: There are different types of solar panels. Photovoltaic for electricity, and thermal for heating water, and passive for heating air. So it would help if you would say what type you are going to build. Theere are a lot of videos on you tube on how to make solar panels. use the link below.

Q:The inverter I am using gets the required 2 DC volts from the solar panel, but fo some reason it just won't output the 0 AC voltage. When the inverter is hooked to a car battery, it works just fine off the same 2 DC rating. Help me out please...: There could be a couple of reasons why it isn't working. First, 2V panels actually put out a considerably higher voltage because it is presumed that they will be used to charge a 2Vdc battery. That requires applying a voltage greater than 2Vdc, and usually there is a solar controller that regulates the solar power to the battery. It also has a voltage drop. Look at the first reference reference, and you will see these values for a particular panel: Voc: 2.6V (open circuit voltage) Vmp: 7.2V (voltage at maximum power point) Voc is the voltage the panel produces under standard sunlight and temperature conditions (25°C), with no load applied. As load is applied, the voltage drops (see reference 2). Power is the product of current times voltage, so at one set of conditions (namely at Vmp) maximum power is available from the panel. Your inverter might not be working for either of two reasons: ) it has input protection circuitry that locks out operation when it senses an overvoltage, as in the 2.6V open circuit voltage, or 2) the panel does not produce enough current and the voltage from the panel collapses under excessive load. For example, if you load your inverter to 20W, then nominally the 2VDC input to the inverter must supply 20W/2V/eff = 0A/eff Assuming the inverter has an efficiency of 80%, the input current required is: 0A/.8 = 2.5A A solar panel operating at maximum power would need a rating of about: 2.5A x 7.2V = 25W Is your panel that big? The other option, as mentioned by others, is to charge a battery that runs the inverter. Other nuances: Voc increases as temperature decreases. Sunlight intensity varies (obviously), so the panel may produce less than rated power. The power specifications often are printed on the back side of the panel.

Q:Is there a small solar panel system that I can put in my bedroom window and charge my phone and run an alarm clock off of? Or one I can run a microwave off of?: You can cosider this product Flexible Personal Solar Panel. I think it will be helpful. Product Review Take the lightweight, easy-to-pack Brunton Solaris 6 / 2 Solar Panels on your next expedition to the Himalayas or down that nearby trail or dirt road. Brunton used CIGS, the most efficient thin-film solar technology available, to create the Solaris. Choose either the Solaris six-watt or 2-watt panel—both of them fold up to the size of a CD wallet and work, even in overcast conditions, to charge your cell phone, digital camera, camcorder, iPod, and other small electronics. A built-in reversing diode prevents the solar panel from discharging your batteries when the sun disappears for the night. Brunton's Solaris 2-watt panel can even charge your satellite phone or trickle charge your laptop.

Q:does anybudy know about solar panels? plz reply me: Solar panels, often connected to other panels to form an array will produce electricity when exposed to the sun. At this time solar panel is one of the fastest growing business in the world. Given the fact that most of our energy comes from fossil fuels (Oil, Natural Gas and Coal) and that those resources are getting used up and more expensive to get to, and given the fact that solar panels are getting cheaper and more efficient, eventually, the electricity produced by solar panels (or photovoltaic panels as they are sometime called, PV for short) will be cheaper than that of CO2 spewing electrical plants. Actually, it could be argued that if the coal, natural gas and oil industry was not subsidized so much by our governments, and if you demanded that the process of producing electricity from those sourced be as clean as PV, PV would be a cheaper source of electricity than fossil fuel already. Make sure to also look into the solar panels that produce hot water. SHW (Solar Hot Water) is very developed in country such as Israel, where the law demands that all new house be build with SHW systems. Those panels are very efficient at capturing the heat of the sun and produce hot water much cheaper over their life than using gas or electricity.

Q:i want to know how to hook up solar panels to my existing power. all i can find on the internet is to use batteries and a inverter. but i want to use all of my existing lights and outlets off of the solar energy. i have heard that you can actually turn the meter backwards and use supplied power when needed. thats what i want to do and is it possible to do myself and if so, how?: Contact your power company. They will advise you of the proper configuration. If you try to attempt this without notifying the power company and something goes wrong, they can and most likely will hold you responsible for all damages.

Q:There are places in the US where it is sunny almost all the time, like the southwest. But if we covered an area of the Sahara with solar panels, the sun exposure with the area would generate enough energy for the whole US at least. Plus, I would imagine it would be a great source of income for those countries.Why isn't this a topic under discussion or even mentioned between countries' governments/in Congress/in politicians' viewpoints?: Good question. One of the reasons is the greed of manufacturing companies. No matter the profit margin of the product, they seem to want to charge so high a price that the break even point is ten years down the road, so the true savings are few. The cost of solar panels should have dropped way lower than they have by now. I believe that the political correctness of the product will tempt the manufacturers to keep the prices artificially high. One other answerer is right, the panels are very fragile, and damage would destroy the investment, so new inroads need to occur in technology to protect the panels from damage. Somewhere in the middle is a profit for the manufacturers, and savings for the consumer. I hope we find that middle-ground soon.

Q:Can solar panels be used in hot climates?: Yes, solar panels can be used in hot climates. In fact, solar panels actually perform better in higher temperatures as they rely on sunlight rather than heat to generate electricity. However, excessive heat may slightly reduce the efficiency of the panels, but modern solar technology is designed to handle and adapt to varying weather conditions, including hot climates.

Q:Is this true in a dc system? What if my battery current is negative?: complex task. browse in google and yahoo. that could help!

Q:Can solar panels be installed on remote monitoring systems?: Yes, solar panels can be installed on remote monitoring systems. Solar panels provide a reliable and sustainable source of power for remote monitoring systems, allowing them to operate efficiently even in areas without access to grid electricity.
