Q: I mean like bread is made of wheat, what are solar panels made up of?How are they manufactured?
Solar panels (aka photovoltaic panel) are most often made up of thin wafers of crystalline silicon or cadmium telluride. As photons from the sun enter the photovoltaic cell, electrons are freed from the substrate when are then collected by wires that run throughout the panel. And as we know electrons=electricity!
Q: Mono-crystalline or poly-crystalline solar panel?
All solar photovoltaics drop in efficiencies with higher temperatures but it isn't the 45+ C you have to worry about but rather the heat from the sunlight striking the panels. There are hybrid systems which passes water in pipes attached to the back of the solar panels to cool the panels and preheat the water for solar thermal collectors. The difference between mono-crystalline and poly-crystalline are that mono-crystalline are more efficient and more costly to make.
Q: Does a solar panel work under a full moon a tiny bit, or not at all? Likewise, if you used mirrors or lenses the concentrate sunlight, is there a maximum to how much a solar panel can handle?
Under a full moon your solar panels can put out full rated voltage but no amperage. You do not want to put mirrors on your solar modules because you will just simply burn them out. They are made to use what the sun puts out and the extra heat from the mirrors would be too much. Plus you would have to build something to make the mirrors follow the sun or the reflected light would be moving on you all day as the sun moves. If you was to take apart one of those mirror balls that you see on dance floors and put all the little pieces on a board at angles to all aim at one spot. you would have a lasor beam of a sort. You can melt steal like that. Think what that would do to your solar panels.
Q: Can solar panels be used in areas with high winds?
Yes, solar panels can be used in areas with high winds. However, it is important to ensure that the solar panels are properly installed and securely mounted to withstand the high wind conditions. Reinforced mounts and sturdy frames are typically used to anchor the panels securely in place. Additionally, frequent inspections and maintenance might be required to ensure the panels remain intact and functional in such environments.
Q: How long do solar panels last?
Solar panels typically have a lifespan of around 25 to 30 years, although some can last even longer with proper maintenance.
Q: i am starting to consider getting solar panels instead of paying electric bills which are somewhat higher now than they used to be
Here in southwestern Arizona more and more solar panels are getting installed everyday. If it wasn't an economical thing to do I doubt if people would be doing it. Given that because of climate change our summers are getting longer and apparently hotter running an air conditioner gets evermore expensive. Also every year or so the rates go up. At the current rate of increase rates will easily double in a decade. Installing a solar array means that in far less than a decade, given a hefty down payment, any government subsidies and tax breaks in a couple of years you'll own your own electric company. Technically about /4 of the US would benefit from a true government program to install solar panels on all buildings. Years ago it became law that every building had to have electricity, running water and flush toilets. We need a similar law to hurry up a conversion to solar where practical.
Q: My Grandfather just purchased a cheap solar panel kit for his ranch that could not muster enough power to run his mini fridge.He has two 6 volt batteries running positive to negative and would like to add more batteries. Probably 2volt. How would he go about hooking up the other batteries and what kind of wire or coil should he use.Also, I saw on youtube a guy recommending a lead-acid battery from walmart for under $20. I was just going to go to ecology and just pick up some used batteries but I may be wrong.Any help for a first timer might help me and my gramps out will be appreciated.Thank you
Solar charger employs solar energy to supply electricity to devices or charge batteries. They are generally portable. Solar array: electrical device consisting of a large array of connected solar cells Solar Panel is a group of solar cells arranged into a panel that can be installed onto a flat surface. The panel captures sunlight and converts it into DC power.
Q: trees vs solar panels who would win?
If it was a physical battle, solar panels. It's like burning ants with a magnifying glass. Aim the solar panel at the trees and you have a forest fire.
Q: How efficient are the solar panels....?
There is over 000 watts of power in a square meter of sunshine. A square meter panel converts only about 20% of it into electricity (200 watts). At my workplace, I have a photo-voltaic solar panel electrical system. Its maximum capacity is about 25 kilowatts. On a sunny day it will produce about 80 kilowatt hours of electricity, but we average about 50 kwh/day. At current value, that adds up to a saving of about $4,000 per year, which sounds nice but that's only about a tenth of my total power bill. The system cost $00,000. Pay-back is 25 years (which by coincidence is the length of the warranty). To answer your question more directly: solar panels are not quite efficient enough to be economical.
Q: So, assuming that a solar panel is flush with the ground (i.e. only the photovoltaic side is visible, the other sides are covered by dirt,) what would happen if it was run over by a car? How about an SUV? Would it break?Would the solar panel still generate electricity?
