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:in a solar panel, where do the protons go?
Here okorder.com/... Within this structure, the electrons are not really lost from the system. An electron just gets enough energy (from light) to be able to leave its atom, and float freely around the structure. Hence you have electrons in motion, which is the definition of electric current. If the lights go out, the electrons just settle back into one of the atoms that is missing an electron.
Q:what is solar panel? full description needed?
Solar energy begins with the sun. Solar panels (also known as PV panels) are used to convert light from the sun, which is composed of particles of energy called photons, into electricity that can be used to power electrical loads. Solar panels can be used for a wide variety of applications including remote power systems for cabins, telecommunications equipment, remote sensing, and of course for the production of electricity by residential and commercial solar electric systems. On this page, we will discuss the history, technology, and benefits of solar panels. We will learn how solar panels work, how they are made, how they create electricity, and where you can buy solar panels.
Q:how many solar panels and what type to power a laptop computer that has to be plugged in when in use?
Yes. Basically, here's what you need (I'm keeping this general on purpose): The panels themselves -- how large an area depends on average power consumption and how much power you can get on average. That, in turn , depends on climate. You'd need more in Seattle than Tuscon, for example. I'd guess something in the neighborhod of 0 square feet. Depends also on haow many gadgets (printers, etc.) you have. You'll need a power storage system. Lithium gives you the best poser density (of off-the-shelf stuff) but an ordinary car battery works well and is reliable. And, of course, a control system to manage the power generation/storage/use so everything works together without that annoying smell that tells you you just cooked a few hundred bucks worth of equuipment! :)

Q:Maintenance for solar panels....?
New sunlight panels are easy and shiny they usually look cool. Then they get dirty with dirt and particles caught on the wind and residues left in the back of by rain and birds. Solar panels need to be by and large cleaned and maintained to be able to hold them running effectively and maximize the quantity of sunlight they convert into electricity. Unlike home windows your sun procedure wants to have a clean and clear surface to make sure they are working at their highest efficiency. If they are not at their surest performance it approach they are not producing the amount of electrical energy that they might be. Sun panels will attract filth, dirt, soot, pollen, tree sap and salt crystals in coastal areas creating a nice layer of dust. This sediment reduces the amount of light reaching the silicon cells underneath the glass floor and reduces the panel's effectiveness. A solar panel that has on no account been cleaned would be producing almost a 3rd less power than it or else could be. Some have mentioned a ten to fifteen percentage lack of sun output as a result of dirty panels. From the ground the panels may just appear to be clean, similar to your windows. Up close nevertheless you will see the grime that has built up from the grime and pollution within the air. A extra visible deposit that can be left on panels is fowl droppings. These tend to wholly block the sunshine from areas of the photovoltaic panel and may colossal scale back its effectiveness. See much more about sun panels preservation beneath link
Q:Solar Panels Project?
any type
Q:simple definition of how a solar panel works?
Sunlight (photons) hit a piece of silicon and knock electrons out of it. That causes a flow of electrons, which is electrical current. simple enough? a better explanation from wikipedia: A solar cell is a device that converts the energy of sunlight directly into electricity by the photovoltaic effect. Sometimes the term solar cell is reserved for devices intended specifically to capture energy from sunlight such as solar panels and solar cells, while the term photovoltaic cell is used when the light source is unspecified.
Q:Do grid-tied solar panel systems have to be installed professionally?
Solar panels have to be installed by a professional in order to get the government rebates. Also the systems must meet state and local electrical codes. Most modern inverters will not turn on unless there is live power from the MAINS, so a ultility company is NOT required for any installation anywhere. There are plenty of electrical contractors and speciality solar contractors out there to help you to make sure that the system is properly designed with the correct components, properly installed, and legally certified. Also many states require a permit that may have a large fee before any installation and may not allow the homeowner, especially for city homes, so it is best to check first. You might be able to get away with it if you live in the country, but consider the safety as well. See if you can work with your contractor to get the materials that you both agree upon as well. They can help guide you based upon their experience. Also shop around for pricing as the panels are now going below $ per watt !
Q:Solar panel placement idea?
It will generate MUCH more current if placed outside of the window. The best position is pointing directly south. Over the period of one day, you will get the most average sunlight pointing in that direction.
