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:Can solar panels be used on a backpack or portable device?
- Yes, solar panels can be used on a backpack or portable device. These panels are typically lightweight and flexible, making them suitable for integrating into various portable devices. They can capture sunlight and convert it into electrical energy to power or recharge these devices while on the go.
- Q:My project needs to build a thermal solar panel that would be used as a demonstrational rig. The dimensions i am allowed do not allow me to use a normal thermal solar panel so i have decided to use the heat exchanger from the back of a fridge. Although this is possible to use what equation would i use to prove the power of the sun would actually heat up the water. More importantly when the rig is demonstrated to students, they will need to be able to determine if the raise in temperature given by the thermometers is what should be given. Variables of the rig will include: Angle of the panel, Light intensity, Direction of panel, and more importantly the flow rate of the water travelling through the pipes. What equation includes those variables (change in temperature, flow rate) and would allow me to incorporate the angle of the panel. The light source would be a lamp so i would also need to know how much of the energy from the lamp is actually being used by the panel?
- If you only use it for demonstrational . 75W-00W small solar panels would be that you are looking for, you can use it heat up the water. With simple guide you can do it yourself easily and cheaply.
- Q:how long till a 50 watt solar panel pays itself off in buffalo, ny if its $500. i have national grid and heres the link to the rates. i am residential.
- the Department of Energy has a ' solar hours calculator for locations around the US factoring in hours of sunlight.....the other factor is how perpendicular to the sun the panel is.....as a wild guess I'd say Buffalo's solar hours factor is about 3....which means as an average over 365 days you get 3 hours a day of maximum ( 50 watts ) output. So 3 x 50 x 365 = 64.25 kWh a year. At, say, 5 cents a kWh, you're making $24.63 a year worth of electricity. See why the houses of upstate New York..let alone Ohio or Virginia or Georgia.....aren''t covered in panels?
- Q:Is there a small solar panel system that I can put in my bedroom window and charge my phone and run an alarm clock off of? Or one I can run a microwave off of?
- You can cosider this product Flexible Personal Solar Panel. I think it will be helpful. Product Review Take the lightweight, easy-to-pack Brunton Solaris 6 / 2 Solar Panels on your next expedition to the Himalayas or down that nearby trail or dirt road. Brunton used CIGS, the most efficient thin-film solar technology available, to create the Solaris. Choose either the Solaris six-watt or 2-watt panel—both of them fold up to the size of a CD wallet and work, even in overcast conditions, to charge your cell phone, digital camera, camcorder, iPod, and other small electronics. A built-in reversing diode prevents the solar panel from discharging your batteries when the sun disappears for the night. Brunton's Solaris 2-watt panel can even charge your satellite phone or trickle charge your laptop.
- Q:I really need to know about the good companies who are selling good quality home solar panels.I lives in Pakistan, solar panels sell here are cheap but they doesn't work for long time, mostly they are quot;made in chinaquot;.Consumption of units of our house written on our electricity bill is 300.My dad is seriously thinking of purchasing a solar energy system for house that long last and works efficiently.So plz help me out.
- Solar power systems are expensive and it takes time to recover the initial investment. The cheap solar panels that you are talking must be solar heat collectors which are most common in Asia. They are the most efficient type of solar power systems for the climate in South East Asia. They are mainly used to heat water. If you are looking for this, it will cost you about 25000-30000 for a 50-200 liter capacity. If you are looking for a solar power system only, then you can expect it to cost about 50000-60000 Rs approximately for 00 Watt/hr system. With this you can run most of the appliances and lights, fans etc. and your electricity bill will only be a fraction of what it is now. Hope this helps.
- Q:I paid for an appraisal and the home was valued at $25,000. The problem I have with this is my house is equipped with solar panels. I paid about $25000 for them. A comparable house sold for $225,000 4 months ago. Same amount of rooms, bathrooms, square feet, lot size and curb appeal (landscaping). But no solar panels. Home prices in my neighborhood have also gone up. I would like to know if there is any way I can dispute this as I feel I just wasted a lot of money on a incorrect appraisal.
- Normally solar panels are listed as part of the house that supply heat, like a water heater or furnish. Your house would be appraised the same without the solar panel. Since the house you are references sold 4 months ago this might not be a comp your appraiser would have used. Normally a house would have to be sold within the past 90 days to be used by an appraiser. You are able to challenge the appraisal of the house you paid for. The appraiser would take a second look at the cops he/she used in coming up with the valuation of the property and see if here was something that was over looked. If you want to challenge the appraisal based on the fact that you have solar panels, it is doubtful there would be any changes. By adding the solar panels to your house might have been over built your house for the neighborhood. Look around your neighborhood to see how many other houses have solar panels. Normally in an area where houses are valued at around $200K or so would not normally be equipped with solar panels. This would not add value to your house as other houses in your neighborhood would still appraise for the same, since they would not have solar panels as the house you indicated in your statement did not have. I hope this has been of some benefit to you, good luck. FIGHT ON
- Q:Can solar panels be used to charge electric vehicles?
- Yes, solar panels can be used to charge electric vehicles. By installing solar panels on rooftops or in parking lots, the energy generated from the sun can be used to charge the batteries of electric vehicles, providing a clean and sustainable source of power. This helps reduce reliance on fossil fuels and promotes renewable energy use in transportation.
- Q:our school spends around $0,000 dollars on energy.we want to know how much money would installing solar panels on the roof save our school.
- What you are really looking for is ROI. Return on investment. If you spend 0K up front how long will it take to recoup that 0k. The answer is too long. Solar panels are not and never have been about saving money. They are about trying to save the planet. So if your school wants to go green then they should do it but the overall cost will be higher.
- Q:Can solar panels be damaged by hail or extreme weather?
- Yes, solar panels can be damaged by hail or extreme weather. Hail stones can cause cracks or dents in the panels, compromising their efficiency and potentially leading to water leakage. Additionally, extreme weather conditions such as hurricanes or strong winds can dislodge or break the panels, causing significant damage. It is important to consider the durability and quality of solar panels when installing them in areas prone to such weather events.
- Q:How do solar panels affect the property's LEED certification?
- Solar panels can have a positive impact on a property's LEED certification as they contribute towards earning points in several categories such as Energy and Atmosphere, Sustainable Sites, and Innovation in Design. By generating renewable energy and reducing the property's carbon footprint, solar panels can help achieve higher energy efficiency, promote sustainable land use, and demonstrate innovative practices, ultimately boosting the property's LEED certification level.
