- Q:What is the impact of roof material on solar panels' performance?
- The impact of roof material on solar panels' performance is significant. The type and condition of the roof material can affect the efficiency and effectiveness of solar panels. Certain roof materials, such as metal or asphalt shingles, are more conducive to solar panel installation and can provide a stable and durable surface for the panels. These materials typically allow for better heat dissipation and can withstand the weight of the panels. On the other hand, roofs with clay tiles or slate may require special mounting systems and can be more challenging to install solar panels on. Additionally, a damaged or deteriorating roof can pose a risk to the overall performance and lifespan of the solar panels. Therefore, it is crucial to consider the roof material and its condition when planning for solar panel installation to ensure optimal performance and longevity.
- Q:Do higher watt solar panels last longer, efficiency-wise? 3 installers gave me quotes with 3 different sunpower panels. The 225, 25, 20 watt panels. Whats the con and pro's of the different wattages?
- Power from solar panels depends upon its proper installation and the brightness of the Sun.
- Q:Got a small project here in a remote location. There is to be a 2 volt deep cycle battery, the equipment to be powered from battery and solar panel to charge battery. The 2 volt battery puts out 55 AH. the max constant power draw from the equipment to be powered is 7.9 watts. Will a 30 watt panel at 2 volts be enough to run this system during sunlight and charge the battery for the equipment to run overnight?And, at 55 AH, how long can I keep a constant draw of 7.9 watts without a recharge?Thanks to all the input!
- o work out the wattage correctly, the panel needs to be sized according to how much power you are going to use. (Later on you're going to need a bit of info on each electrical item you need to be solar powered).
- Q:Can solar panels be used for powering a theme park or amusement park?
- Yes, solar panels can be used to power a theme park or amusement park. They can provide a sustainable and renewable source of energy to meet the power needs of various attractions, rides, and facilities within the park. By harnessing sunlight, solar panels can generate electricity that can be used directly or stored in batteries for later use. This not only reduces the park's carbon footprint but also helps to lower operational costs in the long run.
- Q:Do solar panels require regular maintenance?
- Yes, solar panels do require regular maintenance to ensure optimal performance and prolong their lifespan. This maintenance typically involves cleaning the panels to remove dirt, debris, and any other obstructions that may reduce their efficiency. Additionally, regular inspections and monitoring of the system are necessary to identify and address any potential issues or malfunctions.
- Q:first of all, to be honest i have totally no idea on how a solar panel works.my task is to design something like a solar powered street lamp which store sun energy during day time and convert it into electrical energy then light energy so that the lamp can work during night time.any ideas on how to design the solar panel? which can store enough or more enegry in case there is no sunlight another day. and low cost as well :D
- solar panels are designed to charge 2v batteries, now depending on the power you need you can determine what kind to use there are many power ratings for the modules, for example if you want to charge two 2v batteries you can connect them in parallel, if you want to reduce the charging time you can use more than one module in parallel to increase the power.
- Q:i'm making a small solar panel powered fan but it cant run the cellphone vibration motor even i have place two x2 solar panel.
- A solar cell's purpose is to generate electricity through the release of electrons from a material that is bombarded by electromagnetic radiation or photons. Most crystalline solar cells are sensitive to visible radiation from 400 - 700 nanometers, which correspond to 3. - .8 electron volts, of the visible region as shown by ACEPT W3 Group (999) and also into the near infrared spectrum. As the wavelength of the electromagnetic radiation increases, the amount of electron volts decreases. This means that infrared radiation has less electron volts than the visible spectrum of light (because it has a larger wavelength than visible light) and ultraviolet and gamma radiation has more electron volts than both the visible spectrum of light and infrared radiation (because they have a smaller wavelength than both infrared and visible light). Abramowitz, M., Davidson, M., Neaves, S. (2003) wrote that all forms of electromagnetic radiation originate from the atom which contain orbiting electrons around its nucleus. When those electrons absorb more external energy than they can contain in order to be stable, the extra energy is released in the form of an electromagnetic wave. That electromagnetic wave contains a magnetic field and an electric field, one offset by ninety degrees to the other along the propagation plane.
- Q:I have a solar panel 7.5V .25W 50mah, connect 2 in parallel to power a RC boat. The boat use to run on 6cell battery pack - 7.2V 800Mah.The dc motor requirement based on the provided battery pack, i assume would be 7.2V and rated at (7.2V * .8Amp) = 2.96 Watt.Would two of my solar panels run this DC motor ?are my calculations or understanding correct ?do lend a hand dear ''world''
- solar cells are not rated in mah, they are rated in ma or amps. I'll assume this one is 50mA. Two in parallel will give you 300mA, so that will charge a 800mA-hr battery in 800/300 = 3 hours. Theoretically, in bright sunlight if the array is exactly at right angles to the sun's rays. The problem is, depending on the type of cells, the battery pack will need 8 volts or so to charge, and your solar cells won't deliver that. If the sun is at an angle, you may get only 3-5 volts. so you have to put them in series, so you will get only 50mA out of them, which will charge the battery in 6 hours of bright sunlight. Would two of my solar panels run this DC motor ? If the motor is .8 amps, you need the battery, the arrays are not near enough. Or are you attempting to replace the battery pack with the solar array? Your english makes that difficult to understand. If so, put them in parallel to get the 300mA, but that would run the .8 amp motor very slowly. If you had 2 of the solar panels, it might run at close to full speed if the sun is bright and shining directly on all the panels. But where did you get the .8 amps for the motor? The 800Mah rating of the battery has ZERO to do with the motor current. So the answer above is based on your number, which I suspect is totally wrong. .
- Q:I live in Hawaii and having a solar panel is not a bad idea since we have plenty of sun the only problem is that it cost a lot of money and takes many years before you get your money back. There are kits available where you can make and install your own solar panel and wind turbine but is it bull **** or is it a good deal?
- How confusing is this to do? Judging out of your question and rationalization which you posses no information or historic past in this section: Very confusing. Is it useful? no longer even remotely useful. high priced? confident, you will no longer stay long sufficient to make certain a ROI = return on your investment. Will I keep funds or lose funds? you will lose funds, equipped perfect the fee per Kilowatt will a techniques exceed what the electrical powered employer grants for you. If it replaced into elementary, useful, much less high priced and would keep funds you’d see those going up in all places. i understand a great form of very gifted human beings in this section ( consisting of me ) that could try this in a minute if ~ ~ it replaced into elementary, useful and would keep funds. If it’s a undertaking which you’d in simple terms choose to play with, decide for it. yet once you think of you’re going to keep funds, forget approximately it.
- Q:Can solar panels generate electricity during a blackout?
- No, solar panels cannot generate electricity during a blackout because they are connected to the grid and rely on it to deliver power.
