- Q:im aware i dont fully understand. but with what i do. if P = iv, and current changes with voltage, whats the point of changing either. if in any cicumstance, you end up with the same wattage, how does changing either effect a solar setup. (2v panel vs 24v)thanks in advance. explain in laymans if you can.
- The choice of solar panel voltage comes down more to what the panels will be connected to. You're right that power can remain the same at the different voltages. Higher input (panel) voltages are sometimes used in inverter systems to reduce the effect of voltage draw-down. 2v panels (about 20v open circuit) work well for charging 2v batteries, connected in parallel, through a charge controller. For use of a grid-tie inverter, higher input voltages are sometimes used to reduce the effects of draw-down. You want to select and wire (parallel vs. series) your panels based on the input voltage requirement of the load, whatever it may be.
- Q:how to build a solar panel
- Search Yahoo Answers or the internet first, this question is common. It is possible to build a solar thermal panel, to heat either water or air. You can just search YouTube to see how people did it. Try searching solar water heater. If you build a photovoltaic (solar electric) panel on your own, it will only be good for demonstration purposes. The homemade type I've seen produces only microamps of current - not even enough to run an iPod. Be wary of sites advertise you can make your own panel for less than $200 (or some figure), and try to sell you the plans. This is the same information that is posed on other sites for free.
- Q:Are there any limitations to the lifespan of solar panels?
- Yes, there are limitations to the lifespan of solar panels. While most solar panels are designed to last for several decades, their efficiency gradually decreases over time. Factors such as weather conditions, shading, and quality of materials can impact their lifespan. Additionally, some components, such as inverters, may need to be replaced after a certain period. However, with proper maintenance and regular inspections, the lifespan of solar panels can be maximized.
- Q:Can solar panels be installed on a carport structure?
- Yes, solar panels can be installed on a carport structure. In fact, carports are an ideal location for solar panel installations as they provide ample space and can help maximize the energy production potential. Additionally, solar carports offer the added benefit of providing shade and protection for vehicles while generating clean and renewable energy.
- Q:can solar panels have glass between the panels and the sun?
- PV panels do not have to be in direct sunlight. If they are behind glass they need to be well ventilated to remove excess heat. If PV cells connected in series are not uniformly illuminated the series will produce an amount of power that is based on the light on the least illuminated cell. Thus moving a panel back from a window will mean that for large parts of the day it will produce almost no power as parts of the panel are shaded. This applies only when the cells are connected in series. In parallel they suffer no special degradation of production, but just the sum of illuminated cells. This makes a difference when you decide to use a higher voltage panel... high voltage panels are more susceptible to partial shading. But connecting low voltage panels in series gives that same degradation. Stay away from placing a panel back away from the window, or close to the edges of the window, under roof overhangs, trees and surrounding building shade, where possible.
- Q:What in the solar panel wares out so that the panel can not convert the suns energy to electric energy? Please post were you get answers.
- If they get smashed, they won't work. Keep them clean, and they will last many years. I suppose there is a 'limit' to the effectiveness of the cells lifespan, but it must be more than 25-30 years. Just glass, metal frame and silica. No moving parts. Seems like a good deal.
- Q:Dose a solar panel need the entire range or spectrum of sunlight to produce power?
- It's a huge field of study, very important to solar cell development. People are trying to optimize spectral response for sunlight, even for sunlight in specific places. Google solar cell spectral response for many many websites. Most of them are specific to one experiment.
- Q:Do solar panels require regular inspections or maintenance checks?
- Yes, solar panels do require regular inspections and maintenance checks. These checks ensure that the panels are functioning optimally, identify any potential issues or damage, and allow for timely repairs or cleaning. Regular inspections and maintenance contribute to the longevity and efficiency of solar panels.
- Q:Ok, so my homework was to research and write about how solar panels and solar furnaces work and about their construction. We didn't even take one lesson on it in class and we are not allowed to copy and paste much and have to keep it simple wtf? Its soo annoying as we have hardly took it in class. Please can someone help.
- Well solar panels conduct electricity from the suns waves and turns it into dc current then it is either put into a grid tie inverter to change it to AC and it makes you meter go backwards instead of forwards. or if its not a grid tie inverter it is just put into batteries as dc then changed into AC from the inverter and then used for household appliances. nothing really does run on DC that is why it has to be changed. and for solar furnaces if you mean a water heater that works by a substance here in Pa its antifreeze is heated up by the sun in the panel it is in a continous loop and that is what gets heated up the water then flows over tow of the tube that contains what ever substance such as antifreeze and heats the water.were the water and the tube that changes the water from cold to hot is called the heat exchanger. the substance is actually get heated first then the water. solar heating for water accounts for 29% of water heating in the us. Now if you mean solar furnace as in passive solar thats completely different because here in Pa if we want it our houses have to face to south to get the suns rays. (alot more windows) and there is a cement slab placed only on the south side of the house and it has insulation covering it. There is a certain type of glass that is used for this that will allow the suns rays to come in and let the heat in for the summer and also for the winter. the main place for that would mostly be the first floor of the house due to the height of the windows and the angle of the sun(pa in the summer is 73 degrees and in the winter its 27 degrees) thats when the second floor would be ok to heat the rooms. Hopefully i helped and i explained it in a way that you can understand.
- Q:Can solar panels be used to power an air conditioning system?
- Yes, solar panels can be used to power an air conditioning system. The electricity generated by the solar panels can be used to run the air conditioning unit directly, reducing reliance on the grid and saving on electricity bills. However, the feasibility and effectiveness of using solar panels for this purpose may depend on factors such as the size of the solar panel system, the energy efficiency of the air conditioning system, and the availability of sunlight in the area.
