Solar panel working process

In addition to being the ultimate source of all life on earth, the sun is an infinitely renewable, completely pollution-free source of electricity. Instead of burning fossil fuels dug up from the ground in a big power plant – a very 19th century, industrial age approach, when you think about it – solar panels convert sunlight directly into electricity, with no harmful emissions.

The basic unit of a solar panel is a solar cell, which usually consists of one or two layers of silicon-based semiconductor wafers. When struck by the photons in sunlight, the solar cell generates an electrical charge due to the "photovoltaic effect" – which is a pretty good name, since it produces voltage from photons. The flow of these electrons moves in a steady electrical current from one side of the cell to the other.

Dozens of these PV cells are packaged together into solar modules, which in turn are packaged into solar panels that are mounted on a rooftop and arranged to maximize their hours of exposure to direct sunlight. Because the electricity generated by all those solar cells is direct current (DC), it is then sent to an inverter that transforms the power into the same alternating current (AC) used by the appliances in your home and the local utility electricity distribution grid. Increasingly, these inverters are getting "smart," providing data monitoring for solar installation performance and other grid integration services.

 

 

Q: So my buddy and I have an idea to start a small Solar Installation business. Small as in I am only willing to do one weekend a month and two weeks a year(I know it sounds like the reserves). These are my specific question:) What is the average cost in the U.S. to have Solar Panels installed?2) What is the average cost in the state of Hawaii to install Solar Panels?3)Is this a worth while venture? (There's a good chance i'm going to ignore this one anyways LOL!)4)How long does it take to install a photovoltaic solar panel?5)How long does it take to install a hot water solar panel?6)Besides the obvious, what permits are needed to get our start?7)What education or Cert. is needed?8)Average time to start up?If there is any other information you believe pertinent to this subject that I didn't ask directly, please share. Thank you for your help in advance!
Cba to read all that, but all I know is for 3 sola pannles it cost abot 5000 xxx
Q: Hi. I hate the energy company. I hate my carbon footprint. I will likely move to a piece of property and put a decent-sized mobile home on it. I want solar panels so I can get my own power. I live in the state of Wisconsin. How much would this approximately cost? Would I need certain permits? How many panels can be used? Thanks for helping!
I was in debt up to my eyeballs, and I needed help fast, so I looked to some free online programs. I had tried so many that were scams, but I finally found one legit one! In two months, I paid off $3000 of my debt.
Q: about solar panel
The answer depends upon the type of solar energy captured . Photovoltaic Solar Panels convert the energy into electricity. This electricity is ran throughout the building via wires. Thermal Solar Panels typically capture the energy in the form of heat. The hot water is circulated through the building in water pipes.
Q: Can solar panels be installed on warehouses?
Yes, solar panels can be installed on warehouses. In fact, warehouses are ideal locations for solar panel installations due to their large roof spaces that can accommodate a significant number of panels. The ample sunlight exposure and lack of shading make warehouses a perfect fit for harnessing solar energy. Additionally, solar panels on warehouses can help reduce electricity costs and contribute to a greener, more sustainable energy source.
Q: Need solar panel info with dimensions and also the total cost of the whole equipment for setting up of the required solar panels for a 2-story home
Please excuse my bluntness, but you are not ready to ask these questions. This is a very complex issue. The how many question depends on what you expect of the system. Are you attempting to be off the grid? If so the system will have to supply all of your electrical needs, including those at night. You would need batteries. If you will be on the grid and want to supply all your electrical needs, your system will have to average the total daily usage. This will vary from one season to the next, so you will need to find out your annual usage. If you just want to reduce your electric bill, you need to pick the acceptable installation cost, and work with it to determine what it will buy In your shoes I would do some studying. Check out solar panels in the green search box above, and on the Internet. This will help you ask questions that are easier for us to answer.
Q: Are solar panels worth it?? I mean the price you by for them up front is a lot, so you properly need a loan for it. So how does it work? Won't the loan be just as much as you electric bill?Im just really confused about it.
Solar panels are one of today's best investments! With a lifespan of 25 to 30 years minimum, and a payback period of 0 year or less, the economics are a no-brainer. There are often state loan programs giving you low interest or no interest for a length of time. There are also tax credits and rebates that take care of a lot of the up front money. Calculate for yourself what you will pay to your utility over the next 30 years. Then see how the cost of a solar electric system compares. My company has helped scores of homeowners and business owners claim Independence and take control of their energy costs for the next few decades. Contact us to have a site evaluation and payback analysis for your particular situation.
Q: What is the impact of roof shading on solar panels' efficiency?
Roof shading has a significant impact on the efficiency of solar panels. When a roof is shaded, whether by nearby trees, buildings, or other obstructions, it reduces the amount of sunlight reaching the panels. This shading creates areas of lower or no sunlight, resulting in decreased energy production. Therefore, minimizing roof shading is crucial to maximize the efficiency and overall performance of solar panels.
Q: a fiber optic network could distribute solar energy from warm states to the rest of the country. Using a Federally created program,the energy would be used through a trust program to benefit all of our citizens equally. It would create thousands of jobs and help us with our dependence on foriegn oil supplies. This is no different than work programs created by the Feds during the 930's depression era.
Claire's argument doesn't make much sense to me either. First; Claire is talking about the second law ('you can only lose or break even'), not the third law ('you can't get to absolute zero'). Easily confused, but not that important! Putting a solar panel down _can_ increase the heat absorbed by Earth. Everything has an 'albedo' (the proportion of incoming light it reflects), and Earth's average albedo is about 0.3 (ie 30% of incoming light is reflected, most of which leaves the atmosphere straight away). By putting a 0.05 albedo solar panel down on a 0.3 albedo surface, you increase the amount of sunlight that is absorbed by Earth and therefore contribute to warming. This heat is re-radiated at the Earth's temperature, in the right wavelength range to be absorbed by greenhouse gases too. If you put a panel down on equatorial ocean, or a black roof, however, there is pretty much no effect (since the albedo change is small). Also, the heating effect only lasts as long as the panel is there. Most panels are estimated to last 50 years, meanwhile CO2 has a mean lifetime of 00+ years. I did some maths and found that the 00 year averaged change in radiative forcing for solar panels was negative compared to the UK electric grid, because the reduction in CO2 emissions has a larger effect than the change in albedo. If I have spare time tomorrow I'll redo the calculations and share them. The albedo change has to be considered though!
Q: Okay, so I have a science fair coming up soon and I need help with my project. SO - What should I use to demonstrate with the propeller? A toy boat? Plane? And I only have mini solar panels ; so how do I put the solar panels on the toy boat/plane to make the propeller move off of the sun's energy? Thanks. Steps please!
Solar panels produce electricity. To move the propeller you need mechanical motion. An Electric motor converts from electrical to mechanical power. Most Solar Panels produce DC electricity as do batteries so you need a DC motor that is sized to match the Output of your solar panels. For small temporary projects like this I find that hot melt glue is great to assemble parts. Using a voltage meter you can expose your solar panels to a strong light (or one equal to what you expect during your demonstration) and measure the voltage across the terminals. This may help to size the motor. It depends upon the size of your propeller and how it is made. Your three choices are to use it to power an airplane, to power a boat underwater or to power a boat like an air boat. You might also use the air boat concept to make a car. (air car) The air boat might be the simplest to make but you will need a body of water to demonstrate the concept. The air car doesn't have such a requirement.
Q: i wanted to buy solar panels but this guy told me one will just power one light bulb what i want to know is how much thay cost and is it true tat if more power leaves your house than goes in the power company has to send u a cheek
If you want to get money from the power company you will have to basically put in $0k to $20k worth of solar panels. Currently most solar panels that are available to home owners are not all that efficient. I currently have 3 that are 2 foot x 0 foot on my roof that follow the sun and they only power my water heater. Also some states will give you a tax rebate for installing solar power banks on your roof, mainly in the southwest.
