- Q: is this fact true? - its a limitation to solar panels during summer when it's in extremly hot countrie. I've heard it from my science teacher .. please give detail if you have any and any more benefits/limitations is welcomed .. Thank you :) !
- A good sunny day is best but allthough high temperatures will effect the output from the panel it will not be as affected as much as a cloudy day would.
- Q: What is the main material for making solar panels?
- You can also according to their own needs, according to the power to buy a good package of solar photovoltaic products.
- Q: I need to power a series of meraki wireless repeaters that plug into a standerd wall outlet. consuming 5v or .08 amps However I need this in a remote location (like out in the middle of nowhere) Using A solar panel as power supply and a battery to store the energy but, how and what do I use to convert the energy coming from the solar panel to the battery and the batteries power supply to match the needs of the meraki wireless repeater? How do I make this as compact as possible? Do I need a ac/dc converter? or dc/ac converter? Any suggestions or solutions would be great !
- Search the web for some of the inexpensive solar Cell Phone Chargers. They can be hooked in series or parallel as needed to get you teh voltage and current needed. The 80mA is not too tough, thats not much current. Suggestion is to use a battery that is constantly trickle-charged by the solar panel. This will assure operation on a cloudy day or at night. Another strange source for solar panels and solar charge systems is, believe it or not, Harbor Freight Tools. they are on the web as well as have stores all over.
- Q: i am trying to figure out how many solar panels can be placed on one acre of land and how much they cost to install
- There okorder / Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!
- Q: Can solar panels be used to power an air conditioning system?
- Yes, solar panels can be used to power an air conditioning system. Solar panels generate electricity from sunlight, which can be used to run various electrical appliances, including air conditioning units. By harnessing solar energy, it is possible to power an air conditioning system without relying on traditional power sources, leading to energy savings and reduced carbon emissions.
- Q: How much space is needed to install solar panels?
- The amount of space required to install solar panels depends on various factors such as the type of solar panels, their efficiency, and the energy needs of the property. Generally, a typical rooftop solar panel system requires about 100-400 square feet of space for every kilowatt (kW) of solar panels. Additionally, open areas or ground-mounted systems may require more substantial space. It is recommended to consult with a solar installation professional who can assess the specific requirements based on the location and energy goals.
- Q: How long does it take a 5 watt, 2 volt solar panel to charge a 2 volt R.V. battery?
- It is related to the size and capacity of your battery.
- Q: why don't we take a cue from mother nature and make our soar panels like trees? thousands of leaves or needle (like a pine tree) instead of one big flat panel? I mean it seems to work pretty good for all the plants i see why would it not work for us. It would be aesthetically pleasing and with the right engineering wouldn't it make them not have to worry about tracking the sun? i already have some ideas about the process of making them just no available labratory.
- Because we and the trees are trying to solve a different problem. We want electricity, a tree wants light (and some heat) for photosynthesis. In getting the electricity we use Silicon for solar panels. (Sometimes Gallium Arsenide). And we exploit the same thing in Silicon that allows them to be computer chips. The fact that they conduct differently when voltage is applied. But for a solar panel that is done essentially in reverse. We GET a voltage difference (electricity) from shoving energy through it. Look up junction bias on google or yahoo for explanation. But the DESIGN problem is: You have to couple these panels together the right way - according to their bias. You can't string them up willy nilly. There is a pattern. And when one breaks in this pattern. (I mean when the actual panel cracks, which they do easily as they are brittle). It can change the overall bias. This can make even be worse than if it was removed, it can actually fight against the working ones. The efficiency is there in arranging them like a tree, but the practicality of maintenance would be daunting.
- Q: i've heard environmentalists like ed begley jr use the phrase quot;peak shaving hourswhen talking about solar energy.what does that phrase mean, please?thank you to all who respond.
- You okorder /... This is known as 'Grid-Tied' Solar in the open market.
- Q: Can solar panels be installed on greenhouses?
- Yes, solar panels can be installed on greenhouses. In fact, it is a popular practice as it allows for the dual use of land and maximizes energy efficiency. The solar panels can provide electricity for both the greenhouse operations and potentially for other nearby buildings or the grid.
