- Q: I am doing a report about solar power and I need to know what determines the amount of electricity produced?example: exposure to sun, angle of panel, qualityplease tell me as much as you canmuch appreciated
- irradiance in watts/meter^2 (000-800w/m^2 depending on air quality) COS of angle to the suns rays efficiency of the panels (usually about 5%) age of the panels(one dead cell can drop an entire panel from the array) how dirty are the panels (dust, bird poop, leaves, shading) efficiency of the inverter (usually about 90%) All of these factors affect the amount of electricity produced. One other consideration is that in areas of extreme hot and cold the band gap of the silicon is changed.
- 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 fast does a 25watt solar panel generate power to a battery? trying to figure out a conversion factor here to get a rough estimate of how many i would need to power my house, please help?
- If your house already has utility power, then your best move is usually to stay connected to the utility even when you install solar. Then, there are no batteries involved. Also, you never need to worry about not having enough power on cloudy days or at night. During the day, the solar panels drive the electric meter backwards, building up a credit with the electric company. Then at night, the meter runs forward normally. What you end up with is a very small electric bill instead of no bill, but the net cost is a lot less than using batteries. As to how large a system or how much it will cost, you would call a professional to size your system and give a quote. You can always say no if the numbers don't work out.
- Q: I'm doing a project for school and I'm a little confused about energy and solar panels. I'm looking to propose installation of solar panels to power the computer lab at my school. From what I've read a computer and monitor use roughly 350 watts per hour. I was looking at solar panels and it says they produce various wattage. For example, I was looking at one rated at 200 watts. Does that mean 200 watts in a day? Or per hour? Please help.
- The rating of a solar panel is a maximum continuous rating. A 200 Watt panel will give a maximum of 200 watts under ideal conditions. A computer and monitor use about 400 Watts. not per hour - watts is Volts * Amps and a measure of Power. In hour a computer and monitor uses 400 Watt hours (Wh). Wh is a measure of Energy. To power a lab of 0 computers you will need 0* 400 = 4000 Watts. To run this from solar panels through the day only you would need a 4000 Watt panel. Except - its cloudy, the sun is in the wrong place - many factors reduce the output. To be reasonably safe you would need about a 2000 Watt panel. Then you would need batteries to store power through dull periods AND a voltage converter to change from low voltage DC from the solar panels to the mains voltage for your computers.
- Q: How can I know the right type of solar panel to choose for my small village house in Africa?
- The power output of a solar panel uses a formula to determine kilowatts produced per hour per square meter per day. This calculation is important because, if you plan to install a solar power system for your home, you will want to know how many solar panels will be needed. To calculate solar power requirements correctly, you need to gather the data that is needed for the calculation. First you have to find the average amount of solar radiation available for your area. You can use a solar radiation chart. This can range from a 4 to a 7 depending on the area you live in. Write the number down on a piece of paper and indicate it with the letters RA. Next is determine the amount of electricity that you use daily. Add the kilowatt-hours used per month from your utility bill. Multiply this number by ,000 to get the watt hours in a month. Divide the total by 30 for the amount of electricity you use daily. Write this number down and indicate it with the letters DE. Determine the percentage of your home that you want to power with the solar power system. Write this number down and indicate it with the letter P. Determine the system inefficiency factor for the solar power system. You should be able to find this on the brochure for the system or from the manufacturer's web site. Write this number down and indicate it by the letter I. Determine the power or yield that is required for your home. Use the equation P = I x (DE x P) / RA to find the power requirements in kWh. Divide the number from Step 5 by the peak wattage for a single solar panel to determine the number of panels you will need for your home. Goodluck! :)
- Q: How do solar panels impact the local economy?
- Solar panels can have a positive impact on the local economy in several ways. Firstly, the installation and maintenance of solar panels create job opportunities, stimulating employment and income generation within the community. Additionally, the use of solar energy reduces reliance on imported fossil fuels, contributing to energy independence and reducing energy costs for both households and businesses. This can lead to increased disposable income, which can be reinvested in the local economy, supporting local businesses and promoting economic growth. Moreover, solar panels attract investment and contribute to the development of a clean energy sector, positioning the community as a hub for renewable energy innovations and attracting more businesses and investments in the long run.
- Q: i'm talking abt bulk panelling, how many MW do we get from km sq?
- As okorder / They are working on a reactor that makes diesel and electricity concurrently out of coal, biomass or possibly garbage in a non-polluting process.
- Q: I want to put a solar panel(s) on my roof. What components do I need besides the solar panels? solar power controller? wires? How do I hook it into my home's electrical system and about how much electricity could I generate and save? Would the panels pay for themselves over time? Any help will be appreciated. Thank you!
- The first thing that you have to realize is that solar panels only make DC currant. This is used to charge batteries which when hooked to an inverter will make 20 v. AC. You need a large bank of batteries and a heavy duty inverter to power your house. There is also an automatic switch that will send power back to the utility company when you have excess power available. This is not a small project. Really think this out before you invest a lot of money for nothing.
- Q: Can solar panels be installed on a hospital or medical facility?
- Yes, solar panels can be installed on a hospital or medical facility. In fact, many hospitals and medical facilities have already adopted solar energy to reduce their carbon footprint and lower energy costs. Solar panels can be installed on rooftops or on the ground surrounding the facility, providing clean and sustainable energy to power the facility's operations.
- Q: Can solar panels be used to power swimming pools or hot tubs?
- Yes, solar panels can be used to power swimming pools or hot tubs. Solar panels capture sunlight and convert it into electricity, which can then be used to power various devices including pool pumps and heaters. This is an eco-friendly and cost-effective way to maintain the desired temperature in a swimming pool or hot tub.
