- Q:I am learning all about heat radiation in Physics. There is a question I am doing about Solar panels. It asks, why do glass covers improve the efficient of solar panels? I dont really understand. How do they?? thanks :D x
- Clear glass will allow most of the electromagnetic energy of sunlight into the air-tight volume of the solar panel. The light strikes the black coated metal tubes and the black coated backing, and is absorbed as heat. Part of this heat will radiate as infrared radiation, and much of this will leave through the glass. But a great deal of it will initially remain in the metal as heat. This heat will be partially transferred to the surrounding air, but because the glass stops the mixing of this air with the rest of the atmosphere, this heat will stay mostly contained within the solar panel. If the glass were not there, there would be a huge loss of heat into the surrounding air.
- Q:How do solar panels impact the energy independence of a region?
- Solar panels can significantly increase the energy independence of a region. By harnessing the power of the sun, solar panels generate clean and renewable electricity, reducing the reliance on fossil fuels. This diversification of the energy mix decreases the region's vulnerability to fluctuations in global oil prices or supply disruptions. Moreover, solar panels enable local communities to generate their own power, reducing the need for external sources and empowering them to become self-sufficient in meeting their energy needs.
- 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:Can solar panels be used in areas with high levels of UV radiation?
- Yes, solar panels can be used in areas with high levels of UV radiation. In fact, solar panels are designed to withstand and harness UV radiation from the sun. However, it is important to note that excessive UV exposure can cause some degradation over time, so proper maintenance and monitoring are necessary to ensure optimal performance and longevity of the solar panels.
- Q:What is the most efficient solar panel, how many would we need to power the United States, and how much land would it take?
- 50 billion panels million acres nukes are better. MIKE
- Q:I have this question for extracredit and I dont get it?How many 2V,2W PV panels would be required to supply a load that requires a 48-volt supply that can push at least 2.8 amps of current, if you assume each panel puts out A at 2 V? And how are the panels configured to supply the power requirements of the load?
- 4 in series for the 48V, a rack of 3 sets wired in parallel to give the current. (total of 2 panels)
- Q:Can solar panels be used during a power outage?
- No, solar panels cannot be used during a power outage unless there is a battery backup system in place.
- Q:Can solar panels be installed on a stadium or sports arena?
- Yes, solar panels can be installed on a stadium or sports arena. In fact, many stadiums around the world have already adopted solar panel systems to generate clean and renewable energy. These large roof areas provide ample space for solar installations, helping to offset energy consumption and reduce carbon emissions. Additionally, solar panels on stadiums can serve as a symbol of sustainability and inspire others to embrace renewable energy.
- Q:could any tell me what type off panel is the best tube or flat and how much it should be. I live in N Ireland
- the okorder himin solar
- Q:When you get solar panels do you connect them to the grid?
- Sort of. They need to be connected to an inverter that changes the solar panel's DC electricity into AC electricity and it has to be synchronized with the phase of the power grid's AC. It must be done by a licensed electrician.
