Product description

A solar cell, or photovoltaic cell (in very early days also termed "solar battery"[1] – a denotation which nowadays has a totally different meaning, see here), is an electrical device that converts the energy of lightdirectly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon

Solar cells are described as being photovoltaic irrespective of whether the source is sunlight or an artificial light. They are used as a photodetector (for example infrared detectors), detecting light or other electromagnetic radiation near the visible range, or measuring light intensity.

Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 365 watts. The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar modules, a solar inverter, and sometimes a battery and/or solar tracker and interconnection wiring.

Q:How do Solar Panels Work?
A solar panel is made up of many small solar cells. Each solar cell uses light to make electricity. The solar cell uses light to make electrons move. The cell is made up of two different layers that are stuck together. The first layer is loaded with electrons, so the electrons are ready to jump from this layer to the second layer. That second layer has some electrons taken away. It is ready to take in more electrons. When the light hits an electron in the first layer, the electron jumps to the second layer. That electron makes another electron move, which makes another electron move, and so on. So the light started a flow of electrons, or electricity.
Q:in a solar panel, where do the protons go?
silicon based photovoltaic cells used some boron as dopant. i dont understand if that helps supress proton pastime, the way they be conscious boron on supressing run away nuclear reaction.... im clueless as you
Q:do solar panels have to be in direct sunlight?
As above, but also make sure the panels you use will still produce if partially shaded. Some older panels will quit producing if you so much as put your hand over a small portion of it. Newer ones don't do this but are more expensive. As you may need more panel area to produce enough energy to fill a battery (if that is how you go) make sure you have the room/roof area for additional panels.
Q:how does a solar panel works?
Solar okorder.com/ Here I didn't use an inverter since phones are DC powered electronic units. Hope I've been helpful.
Q:what do i have to study to install solar panels?
The only degree you will need is a degree in hard knocks.You will get it from a reliable contractor who has the skill and knowledge with the product.You may want to call the manufacture and see if there any in house schools that you could attend and be certified in their product.
Q:Power tester for solar panel?
Voltmeter.
Q:Im looking at getting solar panels.
Solar panels are very expensive and take many years to pay for themselves. You'd be better off contacting your congressmen to lift bans on Nuclear and other producers of electricity. That would lower the costs and save much more than the hassle of hooking up solar power and batteries etc.
Q:Does a 50W solar panel generate 540kWh?
running six hours a day doesn't mean much. You need to look at the solar insulation charts for your school's geographical location to come up with a better factor. The easiest number for you to use is sun hours. For example, Washington DC averages 4.23 hours. Do a Yahoo search for sun hours and you should find lots of charts. Solar panels rated at 50W give this output at full sun near noon at full brightness (no clouds). The sun hour factor makes it easy to find the equivalent number of full brightness hours. So, using Washington DC as an example you have: 000 panels * 50W * 4.23 sunhours/day = 634kWh a day on average. You state your school uses 88240kWh/month which is 6274kWh a day. This would mean you need ten times more solar panels since there is no way to get more daylight. Be careful to put in all the units in your formula and cancel them out to make sure you don't end up with a nonsense result. The title of the question would be answered as followed: 50W/000 * 4.23 sunhours/day = 0.63kWh/day or 9kWh per month or 228kWh a year. These are annual averages. If you wanted a specific month, you would need the sun hours for that month. Hope this helps.
Q:Making solar panels bad for the environment?
Like any other materials, solar panels need to be manufactured. These components are usually imported, they use energy to produce and transport. However, once you install solar panels, they need little or no maintenance (except cleaning to maintain efficiency) and they use no other resources to produce power. Over their lifespan, they'll produce more energy than was used to be made, so on the whole good for the environment.
Q:Should we subsidize solar panels?
so, you think of that the perfect concept is to easily save specializing in oil and to not attempt to compete? each CON i've got talked to on right here is going on and on approximately how green power is a foul concept? yet, right this is China, with a centred purpose and fairly making it happen... ask your self how far we'd be interior the U. S. without the cons scuffling with us each step of how... how's that buggy whip enterprise going cons? that's what we recommend as quickly as we are saying owing to Republicans do you think of green power won't happen? China's already doing it... we are able to the two capture up, or supply up... and supply up has a huge unempmloyment value related to it...
