- Q:My solar panel is 24long..It is set at 45deg..the arms are 8quot;long to achieve that angle for winter. I need to get to 7deg for summer..how long will the new arms need to be?..in layman's terms please...thx
- You did not give the details of how the legs are attached to the panel. I did some calculations on my right triangle analysis application. Based on an assumption that the legs are vertical and attached to the bottom of the panel top, i calculated the legs must be 6.97 inches long. This compares favorably with the 8 inches you quoted. t If my assumption is true, the leg length for a 7 degree angle is 2.925 inches. The configuration, if my assumption is correct, will be a right triangle. The hypotenuse (longest leg of the triangle) is the panel length and the vertical legs are the supports. If my assumption is incorrect, edit your question to detail the support /panel configuration. TexMav
- Q:I'm going to pitch an idead to my school about switching to Solar Energy. What are positive and negative effects of the solar panels?Also what is the cost for installing them into a highschool?How much would the electricity bill decline afterwards?
- If you hope to get a solar panel that can run appliances and air conditioning.. then you are not even close to being realistic about what solar panels can do. If you really want to install a solar panel array on your home, then you need to talk to a company in your area that designes and installes them because every installation is different.. so you won't get an answer here on Yahoo. You can expect to spend $20,000 to $30,000 that will provide enough solar power for the average home.
- Q:I have this question for extracredit and I dont get it?How many 2V,2W PV panels would be required to supply a load that requires a 48-volt supply that can push at least 2.8 amps of current, if you assume each panel puts out A at 2 V? And how are the panels configured to supply the power requirements of the load?
- 4 in series for the 48V, a rack of 3 sets wired in parallel to give the current. (total of 2 panels)
- Q:Can solar panels be installed on a warehouse or industrial facility?
- Yes, solar panels can be installed on a warehouse or industrial facility. In fact, these large rooftops often provide ideal conditions for solar panel installations, as they have ample space to accommodate a significant number of panels. Installing solar panels on warehouses or industrial facilities can help offset energy costs, reduce carbon emissions, and contribute to the organization's sustainability goals.
- Q:Are there any maintenance requirements for solar panels?
- Yes, solar panels do require some maintenance. Regular cleaning to remove dust and debris is recommended to maximize their efficiency. Additionally, inspecting the panels for any signs of damage or wear, and ensuring proper wiring and connections, are important maintenance tasks.
- Q:i was told that by making a solar panel they cause more pollution than they will end up getting rid of. Is that true?
- A study by the US Department of Energy shows that, depending on your solar panels, the energy payback is to 4 years. Solar panels usually last 25 years, so solar manufacturing is very green. That said, if you buy American made panels, it saves more carbon from the transport costs. Something to consider in choosing your panels.Actually, most panel manufacturers will recycle the panels after you’re through in 25 years. If they don’t, don’t buy those panels. However, it’s hard to say whether people will actually recycle them because most panels are still being used today. So it’s up to you find out about the manufacturer’s panel recycling program. From what I understand, they will come to you and take them away at no charge.
- Q:i check the diodes in the backside of solar panels it reads out to be 0.433 each give me the same result but i was amazed when i check out the last two one which on clamp meter screen give me ''0L'' what this means? is that diode have malfunctions??is this reasons that the output of solar has been decreased?
- First of all, make sure that you are taking readings in the dark (with the solar panel indoors and covered). 0.433 is a reasonable forward voltage for a Schottky diode. Ideally, it diode should read open one way (possibly OL for your meter), and 0.4 the other way. If it's reading OL both ways, the diode is bad. You can either unsolder it or cut it out and verify that it is bad.
- Q:Can solar panels be installed on tall buildings?
- Yes, solar panels can indeed be installed on tall buildings. In fact, tall buildings can provide advantageous conditions for solar panel installations due to their elevated position, which allows for maximum exposure to sunlight throughout the day. Additionally, tall buildings often have large surface areas available for solar panel placement, which can help generate a significant amount of renewable energy.
- Q:Can solar panels be installed on a residential community or housing development?
- Yes, solar panels can be installed on a residential community or housing development. In fact, many residential communities and housing developments are embracing solar energy by incorporating solar panels into their buildings or providing shared solar systems for the residents. This not only helps to reduce the carbon footprint, but also allows residents to save on electricity costs and increase the overall sustainability of the community.
- Q:What is the typical warranty period for solar panels?
- The typical warranty period for solar panels ranges from 20 to 25 years.
