Q:How do solar panels work?
light from the sun hits the atoms and excites the electrons. This knocks the electrons out of the atom and then the electrons travel in a certain direction. This is the basics of electricity... flowing electrons. And so there's your direct current. I'm sure you could find out more by googling how do solar panels work
Q:Solar Panels for Home?
You okorder.com The notion of spinning a meter backward has a lot of people plugging in their solar panel via an inverter- but this is a very bad idea and illegal as well- the power company requires a lockout device they control to kill power in their powlines for servicing and repairs- a plugged in solar panel and inverter can cause them injury or death. If you have about 30,000 dollars to invest (cost will vary), and you are going to be staying in your home for at least 0 years, contact your electric power utility as they will have the progams in place to do the installation on your site, and install the needed equipment for you to be legally grid tied. They will also have your paperwork prepared for your tax person come tax time. Most are actually seeking people out to do this, I won't go into details why, but by listening carefully to the power company in their presentation they will indirectly tell you why. Any installation that is intended to be grid tied MUST be approved by the power company and meet their specifications. Too many people are ignoring this last detail.
Q:Solar Panel Efficiency?
watts of electricity per month is not a valid measure. You want to know watt-hours per month. A fair assumption may be 5 good hours of sunshine per day, or 50 hours per month. Thus, a 200W panel can produce 30 kilowatt-hours of electricity per month. Many more factors are involved, including your controller, battery charger, wiring, and battery system. At a typical retail rate of $0.5/KWh for electricity, this is worth $4.50 per month. Still, solar power can be cost-effective over the long haul.
Q:What is the difference between Photovoltaic Panels and Solar Panels?
Dear friend, Photovoltaic Panels and Solar Panels are the same products.
Q:do solar panels have to be in direct sunlight?
PV panels do not have to be in direct sunlight. If they are behind glass they need to be well ventilated to remove excess heat. If PV cells connected in series are not uniformly illuminated the series will produce an amount of power that is based on the light on the least illuminated cell. Thus moving a panel back from a window will mean that for large parts of the day it will produce almost no power as parts of the panel are shaded. This applies only when the cells are connected in series. In parallel they suffer no special degradation of production, but just the sum of illuminated cells. This makes a difference when you decide to use a higher voltage panel... high voltage panels are more susceptible to partial shading. But connecting low voltage panels in series gives that same degradation. Stay away from placing a panel back away from the window, or close to the edges of the window, under roof overhangs, trees and surrounding building shade, where possible.
Q:solar panels, wattage?
The easy way is to just use the power values. You need 4500W. Each solar panel delivers 00W (from a value in your working). Therefore you need 4500/00 = 45 solar panels. This is a crude calculation, ignoring efficiencies, voltage conversion losses and losses due to internal resistance. You would probably need quite a few more than 45 panels. ___________________________ I'll explain how to do the calculation your way. Each solar panel delivers 00W with a voltage of 2V. So the current is 00/2 = 8.333A. Each solar panel delivers 8.333A at 2V. But you require 8.75A at 240V panel delivers 00W. To get 4500W, you need: 8.75/8.333 = 2.25 times more panels to increase the current AND 240/2 = 20 times more panels to increase the voltage. So overall you need 2.25 x 20 = 45 panels. Of course if the power output of each solar panel is not 00W, you have to change the above calculation accordingly.
Q:Solar Panels in Abu Dhabi, UAE?
I know where in Dubai , just go to Naif road where they sell the satellite equipment , there are a couple of shops that sell all kind of solar panels and dish equipment stuff. Sorry can't remember the name, But it is right in front of the paid parking lot (the private not public one).
Q:How do solar panels and their battery backup systems work?
Solar panels have their own characteristics and generate current depending on the intensity of sunlight falling on them and not on the temperature. Direction of the panel also makes lots of difference. Nowadays very thin panels are available at very high cost. The more area a panel occupies it generates more current. The current generated by a panel cannot be readily used since the current and voltage varies with the load connected to it. So normally a regulator is used to have constant voltage and constant current to come from the panel. This charges the battery. You have to calculate the total/normal current from the charger and then find the AH of the battery. When you have calculated the AH of the panel/charger then you can divide the AH of the battery by the AH of the charger/panel and find out the time taken to fully charge the battery. You also have to remember that there is a de-rating factor to be taken into consideration in the battery.
Q:Solar panel trouble?
you don't need a capacitor. You can connect it to a light directly. Capacitors rarely break. You can check with an ohmeter.
Q:Do solar panels add to global warming?
If you put a black panel on the ground or on your house and don't connect it to anything, it will absorb solar energy (heat) during daylight and release it at night (radiation). Not exactly. Assuming the black panel establishes an equilibrium temperature, it's going to be losing exactly as much heat as it's receiving during the day. Some will radiate out into space, some will conduct or convect into the atmosphere. As a wild guess, maybe 50/50. If you hook up a solar panel in the same place but hook it up to batteries, charge the batteries during sunlight hours and using that energy to electrically heat the home at night. The panels will absorb solar energy during the day but will convert that to electrical energy in the batteries instead of radiating it back into space at night. The panels are only about 4% efficient, so it's the same situation as the pure black panel for 86% of the energy. The remaining 4% will get stored in the batteries and then converted to heat at night. That heat will eventually leak out of the house and warm up the Earth a tiny bit. I think it's much the same situation either way. With the black panel the energy gets radiated / conducted/convected right away. With the solar panel a small percentage is stored and not so much is radiated, mostly conducted and convected. You're partly right as a black panel is going to radiate more into space than a house. But you're taking about maybe some day about 4% of % of the differening radiation/convection/conduction fraction, of the Earth's surface area. Probably not significant.
