- Q:Hi, I am starting to get curious about the pros/cons of installing solar panels - has anyone done it and is it worth it?
- If okorder and I mention them only because they did a retro fit on my Uncle's house in the Florida Keys and a smaller scale system for my in laws outside of Chicago. Both my Uncle and In Laws really are enjoying the cost savings that they are getting each month from their respective systems, and both said that Sun's initial costs were QUITE low. Be sure to have the blessing of your local building zoning departments before installing the panels as some municipalities take issue with solar panels. Also make sure that your roof is strong enough to withstand the weight of not only the panels, but the bracing. Good Luck.
- Q:when we say a solar panel has 20% efficiency, do we mean that it converts 20% of sunlight reaching it into electricity or that it converts 20% of visible light(which is only 7% of sunlight) into electricity?
- That portion of the sun's light to which it responds, of which it converts 20% to electricity.
- Q:How do solar panels perform in areas with high pollution levels?
- Solar panels can still perform well in areas with high pollution levels, but their efficiency may be slightly reduced. Air pollution can cause a build-up of dirt, dust, and particulate matter on the surface of the solar panels, which can decrease their ability to capture sunlight. Regular cleaning and maintenance can help mitigate this impact and ensure optimal performance. Additionally, advancements in solar panel technology, such as anti-reflective coatings and self-cleaning mechanisms, are being developed to address the specific challenges posed by pollution.
- Q:So I want to go completely solar. Do I need the connected solar panels alone for after sundown hours; Do I need something else in order to have energy to run my entire house throughout the night?In other words do solar panels store the energy for after sun-down or do I need other devices to store the energy?
- Unless okorder
- Q:Why should I have a Generator if I have Solar Panels.....?
- Usually, a generator is more cost effective than a battery backup system for your solar panels. Most grid-tied solar arrays are connected to the grid without batteries. My company has installed well over 00 solar arrays for residential and commercial clients and almost none of them had battery systems with them. Many clients asked to see the costs and after that, they agreed that a generator seems better, especially if there is access to fuel readily available. Also, unless there is a battery system, the solar inverters will not operate when the electricity goes out. This is a safety feature, but it keeps you from using any power at all from the panels when the grid goes down. This explains the utility interactive solar inverters compared to the stand alone generators.
- Q:I have to get a lot of information on how solar panels are developed and distributed in America because I have to do two pages on this. Please help me get information in this I really need it!! Thankss...
- The first link below is one of the best sites for recent news about solar panels. You should be able to find stories about solar panels under development today. A little bit of the history: Solar panels have been around for about 50 years now. They were first used to power spacecraft. Solar power for domestic use started to develop rapidly in the 970's during the first oil crisis, but as energy prices fell in the 980's solar development slowed. Most of the large solar panel makers were purchased by large oil companies who seemed not to be too interested in solar. In the late 990's as concerns about both Peak Oil and Global Warming grew there was renewed interest in solar power and a number of new companies were started to develop new kinds of solar panels. Many of these new companies have grown larger than the older solar companies still owned by big oil companies. Over the last 7 years or so growth in the solar market has been explosive with a compound growth rate of almost 40% per year. In 2005 the solar industry for the first time started to consume more silicon than all other electronic industries combined resulting in a world wide silicon shortage that is still with use. New silicon refineries are coming on line and the shortage is expected to diminish by 2008 or 2009. Check out the two links below. They will help you a lot.
- Q:Can solar panels be installed on a mobile home?
- Yes, solar panels can be installed on a mobile home. Mobile homes can benefit from solar energy just like any other type of home. Installing solar panels on a mobile home can help reduce energy costs and increase energy efficiency.
- Q:What is the environmental impact of solar panels?
- Solar panels have a positive environmental impact as they generate clean and renewable energy without emitting greenhouse gases. While their production and disposal have some environmental costs, their use reduces reliance on fossil fuels, decreases air pollution, and mitigates climate change.
- Q:solar panels are way too expensive to buy, can they be homemade cheaply? i want at least 500 watts. everyone on the web sells these instructions, but i'd like a link to free info, if it is really possible for a non-sciencey person to make. thank you
- If you want long term working ones then no. I have not seen the web instructions ones, but solar panels that are manufactured are a lot more complex then simple solar panels that you make in your backyard. Also, you need to have some type of turbine or other thing to change heat energy into electrical energy. For a non science person to try and do this and have it work the first time maybe hard to accomplish.
- Q:When I make a solar panel, what do I use to store the energy. For example I am going to make a solar panel to power my lights in my room. But I dont want the lights only to come on when the sun is out because that would be very pointless. So... Do I use the panels to charge something like a car battery and then run wires from the battery to an extension chord which will go to a surge protector? It sounds awesome, but I have to put it all together. The help is very appreciated. Thank you guys.
- First of all you seem to be talking about making a solar photovoltaic panel instead of a solar thermal panel. Most solar panels will produce DC electricity. Your house uses AC electricity. You can set up the solar photovoltaic panels to send their current to charge a battery bank and then you can tap into that battery bank and send the power to a voltage inverter to change the power to AC. The better inverters will do a better job of this. The system has to be matched and sized properly. If you are not familiar with electrical work you should have someone who is more knowledgeable help or do the work. Good luck with your project.
