- Q:solar panel model HELP!!!!!!!?
- There are different types of solar panels. Photovoltaic for electricity, and thermal for heating water, and passive for heating air. So it would help if you would say what type you are going to build. Theere are a lot of videos on you tube on how to make solar panels. use the link below.
- Q:thermodynamic question that includes heating water with solar panels?
- Good points. I'm new to the solar energy world, but solar just makes sense. Who wouldn't want to make it work? The more I learn the more I think its a great alternative to some of the energy we use. This info really helps.
- Q:Do it yourself Solar Panels?
- Firstly, forget about making your own PV panels, while you can (if your chemistry is up to it and the home lab well tooled up) make a small PV cell, the efficiency will suck and you will never make enough to produce a reasonable amount of power. What you can do is to build your own solar thermal system to produce hot water (solar thermal makes better sense then PV in most domestic situations anyway), black painted central heating radiators under perspex, rockwool behind, small pump running a water/glycol mix through a heat exchanger controlled by some trivial electronics... Job done. As long as you don't try to run too hot, you can get a hundred watts or so of heat per square meter from such a solar thermal plant. Regards, Dan.
- Q:Who created the first solar panel?
- The first photovoltaic cell was developed at Bell Labs in 954. The team included G.L. Pearson, C.S. Fuller, and D.M. Chapin. A panel is composed of many cells. They respond to a wide range of wavelengths, not just UV.
- Q:Is photovoltaic array another name for solar panels?
- Photolvoltaic arry is the more technical name and the more accurate name for solar panels. Photo indicates light and voltaic indicates a voltage is produced.. Array is just a layout of these little light sensitive electricity generating panels. Actually Solar only idicates the SUN and not light in itself..
- Q:How much energy does it take to make, install, and eventually dispose of a solar panel?
- The attached link is to an article from the 200 Home Power magazine. In that article the energy payback was found to be between 2 and 4 years. Newer panels are more efficient primarily because the silicon wafers used today are thinner. The silicon cell embodies most of the energy required to make a solar panel. Today most solar panels will produce the amount of energy required to manufacture them in between about 9 months and 2 years depending upon the specific technology used to make it. Solar panels are expected to produce energy for between 30 and 50 years. Therefore it takes around 5% of their total energy production to produce them. Note that these figures depend upon where the panels are installed. Panels in very sunny areas may generate more than 3 times the energy of panels in a cloudier area. Edit - The energy payback meta-study that carbonates references below mention one particular study Alsema (2000), which the authors used as a baseline to come up with their 4 year payback figure. These studies DO NOT assume ideal conditions. The Alsema study assumes an annual an irradiation of 700 kWh/m2/yr. That is the United States average irradiation and does take into account cloudy weather and the like. Under idea conditions the amount of energy collected can be almost twice as much. Albuquerque New Mexico is an example. The figures I mentioned above are recent values reported by several different panel manufacturers with whom I discussed the issue at the 2006 IEEE 4th World Conference on Photovoltaic Energy Conversion held this May. The very long payback times that carbonate highlights are almost certainly wrong. The study he references concludes that paybacks range between 2 and 8 years with 4 years being the most likely. In my opinion payback times are actually a fair bit shorter based on conversations with the manufacturers.
- Q:Choosing right wattage solar panel?
- 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:Im looking at getting solar panels.
- I recenty had a system installed for my home, you can get a system that will dramatically reduce your over all electric bill for $20K. My system which is currently running my meter backwards from about 8:30 am till about 6pm cost me around $8K, I did get a $0K rebate and I'll get a $2K federal tax credit. I just had the system installed this week, so I won't know how much it will take away from my yearly consumption for a while. I personally think an overall system is a beter financial option. If you get one that just runs your a/c then you lose the benifit of the energy it is producing when the a/c isn't running. It makes sense to have a system to run an item that is located away from a source of electricity, but then you would need to invest in a storage system. The best advice, is to have a contractor come out and give you a quote. You can get a system that will produce part of your electricity all year and you can always add to it at a later time to eleminate your electric bill.
- Q:Using solar panels to replace electrical wiring?
- A solar panel does not replace the wiring in your house. All it does is supply power to the house, the same way a line in from the street does. After the power gets to the house, regardless of how it got to your house, it goes through exactly the same wiring to get to outlets and lights. Your problem is not that the power coming in from the street is insufficient; the power company can supply all you'd ever need. The problem is that your houses are not wired to receive or use more power. You need to upgrade the service panel so it can bring more power into the house, and upgrade the wiring inside the walls so you have the number of outlets and lights required by today's codes and which most of us need for all the things we plug in these days. Solar panels, while they are cheaper than ever, are not a low cost thing to install. It will take years to recover their cost, and if the rules are the same where you are as they are here, you can't use the cost of installing them as a write-off against the cost of the house until you sell it. They are a capital expense, not a maintenance and repair deduction which you can use each year against the income you receive from the rental. Doing a conventional rewiring is your best bet.
- Q:Making solar panels bad for the environment?
- Like any other materials, solar panels need to be manufactured. These components are usually imported, they use energy to produce and transport. However, once you install solar panels, they need little or no maintenance (except cleaning to maintain efficiency) and they use no other resources to produce power. Over their lifespan, they'll produce more energy than was used to be made, so on the whole good for the environment.
