The sleek and futuristic design of solar panels can add visual interest and a sense of innovation to the property, making it stand out in a positive way. Additionally, the perception of the property being energy-efficient and sustainable may increase its desirability among potential buyers or tenants.
- 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: Mono-crystalline or poly-crystalline solar panel?
- All solar photovoltaics drop in efficiencies with higher temperatures but it isn't the 45+ C you have to worry about but rather the heat from the sunlight striking the panels. There are hybrid systems which passes water in pipes attached to the back of the solar panels to cool the panels and preheat the water for solar thermal collectors. The difference between mono-crystalline and poly-crystalline are that mono-crystalline are more efficient and more costly to make.
- Q: They have been around long enough to be cheaper. Unless they are made out of a natural material that is rare and hard to find, there is no reason why they should be so expensive. On another note, I think that all low power devices like cell phones and even laptops should have solar panels. Even if it is not enough to fully power the device for a long period of time, it will provide some electricity savings and with millions of people saving a little power adds up.
- Photo okorder /... Notice it costs over $200 and it takes up a sizable amount of space. Plus you have to expose it to bright sun light. Over all this is not something the average consumer wants to spend money on or fuss with. If something is expensive, difficult or inconvenient to use then people won't use it. Just the basic economics of such a device limits its sales never mind its functionality and usability. Even if you made a small one buit into the cover to extend the battery you won't get much of an extension and you will increase the cost of your laptop. Consider how people shop, will they buy the more expensive laptop for a questionable amount of battery extension? Mass production can lower costs but in order to mass produce something you need a demand that will consume what you produce. But if no one wants the item because of the aforementioned issues than you can't justify mass producing the item. This is like the classic which came first Chicken or Egg problem, one doesn't happen without the other. Cost reduction doesn't happen without consumer demand. This is where tax incentives, subsidies, low cost loans and energy buyback contracts come into play in order to spur on demand and jump start mass production. You could also make electricity extremely expensive by taxing oil and carbon so that a Solar Cell becomes economically competitive to very expensive electricity. Problem with this option is the negative impact high energy costs have on economic activity. Just look at what happened a couple of summers ago when gas hit $4/gal. To spur on demand we need to incentives the use of Solar cells (and other alternative energy). This can be done through several means such as subsidies, tax incentives, low interest loans, energy buyback contracts etc...
- Q: I have a home made 24 volt electric cart. It is powered by two 2Volt deep cycle batteries. Since the motor runs on 24 volts the batteries are wired in series to produce the 24 volts. I only have a 2 volt battery charger, but I also have two 2 volt solar panels. It is a pain having to unhook wires, rewire it, or charge them one at the time.HERE IS THE QUESTION REALLY... Can I wire the two 2 volt solar panels together in series (ie: negative to positive) then connect it to the existing 24 volt system and have it charge the batteries fine. I know basic wiring, but I know nearly nothing about solar panels, will it work fine? will it cause them to break? or short out?(additional info, the solar panels are only rated at 5 amps so it will not overcharge the batteries or anything)
- If the panels are the same, there is no problem in putting them in series. If you examine the panels, they will be made up of about 36 identical cells in series. Ok, now you have 72 cells in series, fine if they are the same. You need (at a minimum) a diode in the line so that when it is dark, the panels do not draw current out the batteries (it wont be much but you might as well block it). You say the panels are rated 5 amps? Those are pretty good sized panels! Unless you have a charging regulator, I guarantee that they Will overcharge the batteries (unless the batteries are huge, like the size of a refrigerator). Did you maybe mean 5 watts? About a foot square? If so, the output is about 300mA (0.3 amps) which will not overcharge a battery as long as it is at least as large as a garden tractor battery. At a 300mA charge rate, it will take a longgg time to recharge.
- Q: Green issues aside, are solar panels worth it, monetarily speaking?I don't mean that my house might be worth more or any of that. All I am asking is this: if I invest in a set of solar panels, will the cost be paid back to me over time? If so, how long will it takegt;Take into account the following:. Currently I pay the electric company around $00 per month2. I use around 400 kilowats of energy per monthI realize that exact numbers are hard to come by, but any opinions are welcome.

- Q: They absorb solar heat and transform it into electricity, so there should be less heat left to warm the planet. Shouldn't we at least plaster all the world's deserts with them?
- No, the top argument is that extra CO2 is inflicting the ambience to keep greater warmth from the sunlight. Having image voltaic panels might scale returned the quantity of CO2 interior the ambience we are putting in it real now via giving us an means source that doesn't emit CO2, and that's approximately it.
- Q: Can solar panels be installed on a building with historical significance?
- Yes, solar panels can be installed on a building with historical significance. However, it is important to consider the preservation of the building's architectural integrity. Careful planning and design are necessary to ensure that the installation of solar panels does not compromise the historical value of the building.
- Q: I have heard a lot about solar panels and I want to know how these solar panels works and is it really possible to generate electricity using solar panels. And what is the cost of getting a solar panel installed?
- solar panels are a waste, I work for the biggest energy producer on the east coast and we are required by some really dumb laws to have many types of energy sources, fo course the only ones we make money on are coal and nuclear, solar panels we lose a ton of money on because they never make up for the cost it takes to buy them, and technology cannot bring them down because their too expensive even with a gov't subsidy bc of the products to make them. Don't waste your time with them, if you want to save money get a wood furnace
- Q: Okay, so I have a science fair coming up soon and I need help with my project. SO - What should I use to demonstrate with the propeller? A toy boat? Plane? And I only have mini solar panels ; so how do I put the solar panels on the toy boat/plane to make the propeller move off of the sun's energy? Thanks. Steps please!
- Solar panels produce electricity. To move the propeller you need mechanical motion. An Electric motor converts from electrical to mechanical power. Most Solar Panels produce DC electricity as do batteries so you need a DC motor that is sized to match the Output of your solar panels. For small temporary projects like this I find that hot melt glue is great to assemble parts. Using a voltage meter you can expose your solar panels to a strong light (or one equal to what you expect during your demonstration) and measure the voltage across the terminals. This may help to size the motor. It depends upon the size of your propeller and how it is made. Your three choices are to use it to power an airplane, to power a boat underwater or to power a boat like an air boat. You might also use the air boat concept to make a car. (air car) The air boat might be the simplest to make but you will need a body of water to demonstrate the concept. The air car doesn't have such a requirement.
