Q:Please tell me what they are made of and how the materials help the solar cell produce electricity. Im doing a science projects so i need help on knowing all this info. Its a debate, so i need correct information please.I will please need more information about the bad things about solar energy and solar panels. Please say what solar panels do to create pollution or do anything that is not friendly to the environment. If you want just give me a website. Thank you
Solar cells are mainly made of a semiconductor called silicon,when sunshine on it,solar energy is converted into electrical energy by photovoltaic.The energy knocks electrons loose, allowing them to flow freely.This flow of electrons is a current, this current, together with the cell's voltage (which is a result of its built-in electric field or fields), defines the power (or wattage) that the solar cell can produce.
Q:How do solar panels affect the overall energy security of a building?
Solar panels can greatly enhance the overall energy security of a building. By harnessing the sun's energy, solar panels provide a reliable and renewable source of electricity. This reduces dependence on traditional fossil fuels and the associated risks of price fluctuations, supply disruptions, and geopolitical tensions. With solar panels, buildings can generate their own clean energy, ensuring a more stable and self-sufficient power supply, which ultimately contributes to a stronger energy security profile.
Q:do solar panels create electricity from the ultraviolet light created from the sun? because they only have an efficientcy of like 8% and this scientist found out a way to collect the visible light also, and he says the solar panel could have an effeciency of up to 80%! so my question really is, do solar penels creat electricity from heat? do you know of anything that can?
Solar panels create a current from light. A photon strikes a crystal lattice and anelectron is freed and flows as a current
Q:Can solar panels be installed on a military base?
Yes, solar panels can be installed on a military base. In fact, many military bases around the world have already implemented solar energy systems as part of their efforts to reduce reliance on fossil fuels and promote renewable energy. Solar panels provide a sustainable and cost-effective source of electricity for various facilities and operations on the base. Additionally, the installation of solar panels on military bases can contribute to energy independence, resiliency, and environmental sustainability.
Q:Can solar panels be used on commercial buildings?
Yes, solar panels can be used on commercial buildings. In fact, many businesses are increasingly installing solar panels on their rooftops to generate clean and sustainable energy. This helps them reduce their reliance on traditional energy sources, lower their electricity bills, and contribute to a greener environment. Additionally, government incentives and tax benefits often make solar panel installations a financially viable option for commercial buildings.
Q:How do solar panels impact wildlife?
Solar panels have minimal impact on wildlife compared to other forms of energy generation. While there may be some concerns about the disruption of habitats during installation, once operational, solar panels do not emit greenhouse gases or pollutants, reducing air and water pollution that can harm wildlife. Additionally, solar panels typically occupy a small fraction of land and can be installed on rooftops or in areas with limited biodiversity, minimizing the impact on wildlife habitats.
Q:What materials are solar panels made of?
Solar panels are typically made of photovoltaic (PV) cells, which are primarily composed of silicon, along with other materials such as metal frames, glass, and encapsulation materials.
Q:Any recommendation for best solar panels?
I have 3 ARCO solar panels and a wind generator on the Boat and it's all I need to live comfortably on 2 volts.
Q:Do solar panels require batteries?
No, solar panels do not require batteries. They generate electricity directly from sunlight and can be connected to the electrical grid to supply power or utilize net metering to offset energy consumption. However, batteries can be used to store excess energy for later use when solar generation is low or during power outages.
Q:I need a solar panel which can light up 4 full loaded 5 rooms appartment houses
good idea going solar, i would suggest doing a google search, as their are many suppliers. then you need to calculate the amount of wattage you think these apartment houses are going to require. volts x amps = watts. if you are going to be off of the power grid, then you will need a way to store excess energy during good times,( lots of sun) in order to use it during bad times ( no sun ). or see if you are able to sell your extra power back to your local power company, check because some companies do not allow this. you could even have a generator for emergencies if you go off the power grid. on final note, solar is a pretty sizable investment up front and your profits are seen mainly in the long run, but you will get energy savings immediately, but more likely those savings will go to paying off the solar panels also, you will need a converter to convert the ac (alternate current) produced by the panels into dc ( direct current ) which is used by the apartments. it will tie in to the existing electrical system in the apartments. i know germany is really pushing solar energy and they offer their citizens some pretty sweet deals to go solar. the companies are profiting from this so i would suggest looking for a supplier in germany, first. they may have better deals, or try bp (british petroeum) they have been in the solar business for awhile. i wish you success!
