Production description
Emerging, third generation solar technologies use advanced thin-film cells. They produce a relatively high-efficiency conversion for the low cost compared to other solar technologies. Also, high-cost, high-efficiency, and close-packed rectangular multi-junction (MJ) cells are preferably used in solar panels on spacecraft, as they offer the highest ratio of generated power per kilogram lifted into space. MJ-cells are compound semiconductors and made of gallium arsenide (GaAs) and other semiconductor materials. Another emerging PV technology using MJ-cells is concentrator photovoltaics (CPV).

- Q: Are there any disadvantages to using solar panels?
- Yes, there are a few disadvantages to using solar panels. Firstly, the initial installation cost of solar panels can be quite high, which may deter some people from adopting this technology. Additionally, solar panels require a significant amount of space for installation, making them impractical for individuals with limited rooftop or land availability. Furthermore, solar panels are dependent on sunlight, so their efficiency can be affected by factors such as weather conditions and geographical location. Finally, the production process of solar panels involves the use of certain chemicals and materials that can have negative environmental impacts if not properly managed.
- Q: I would like to know if I had a mobile kitchen could I power it from solar panels mounted atop the vehicle (truck).(to power electric kitchen equipment, i.e. stove, deep fryer.), instead of propane…could I possibly connect the solar panels to a battery to save my generated electricity? If solar panels would not be enough power could a small windmill suffice…?
- The best way to find out is to determine the wattage of each piece of equipment you want to use and how many hours you want to use those pieces of equipment. Finally, calculate the total number of Watt-Hours you need at minimum. Then you need to research solar panels or mobile wind mills (they need to be pretty huge to get a decent amount of energy I think, so solar power is probably the way to go). You will need to figure out the efficiency of the solar panels, the size of the array, how you will turn it or if you will turn it at all (to face the sun to get the maximum energy input, or maybe to use mirrors so you don't have to turn it. Once you find a good configuration for your mobile kitchen, you need to calculate if the Watt-Hours you will generate on an average day (with average weather) is enough to power the equipment whose energy requirements you previously calculated. Then you have to keep in mind that some days will have no sun, and you may not be working on some days, but you can still capture sunlight. For each case, a large battery array will be required. If you had a guage on that array, you could also hook it up to the a small generator in case you need immediate power. It's an eco-friendly process, but the initial cost is high and it requires a lot of research and planning. This is why most people do not do it--not because they don't want free energy from the sun, but because it's not easy to start collecting that energy in an efficient way. Sorry I couldn't give you more specific numbers, but a solar panel sales agency should be able to estimate whether or not you could do it (they'd probably set it all up for you too). ^_^
- Q: hi so im doing a school project thing and they have a lot of different questions for us that help us decide whether we would rather a city have a nuclear reactor, or solar panel. But i cant seem to get the last 2 questions...help please???so question ........What types of emissions, if any, are produced by each type of generating station? Do these emissions affect human health?question 2.....What are the long term financial costs associated with maintaining each type of generating station?thanks!
- You should research nuclear reactors and their emissions. Mostly it's waste heat, and if they use a water-based cooling reactor, there can be significant emissions of water vapor. Some might consider the spent fuel an emission too. Waste nuclear material disposal is a problem. Research it. Solar panels have no emissions during operation, but there is some nasty stuff emitted when they are manufactured. 2: Maintenance of solar panels is pretty straightforward: keep them clean, trim overhanging trees, shrubs, etc., check for and clean corrosion, contaminants, etc. regularly. Maintenance of nuclear power plants, so far, is a full time job for many technicians and engineers. The recently developed portable (the size of a shed) nuclear generators claim zero maintenance for 20+ years. That's a big improvement.
- Q: Are there any aesthetic considerations when installing solar panels?
- Yes, there are aesthetic considerations when installing solar panels. The design and placement of solar panels should be mindful of the overall appearance of the building or property. Factors such as panel color, size, orientation, and integration with the existing structure are important to ensure that the solar panels blend well with the surroundings and do not compromise the visual appeal of the property.
- Q: How Much energy does Solar Panel Produce,and How long can Solar Panels go without maintenance.
- The available energy is a function of several factors including insolation (sunpower) mounting angle, gathering area, type of cell and conversion efficiency.
- 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
- Build okorder
- Q: What is the working principle of solar panels?
- the material is easy to industrial production and material performance and stability.
- Q: i want to charge my mytouch 3g with solar panel(s) it has a 500mah 3.7v 4.4wh batterieswhat do i need to charge it can i use RadioShack 0.5W Solar Panel 4.5V or RadioShack? W Solar Panel 4.5V
- see u have to make ur own ckt for this ur solar panel generate DC if u want to charge ur phine then its convenient way to harge with ur charger for this do this search for net to convert DC-AC convertor since ur charger work on AC so when ur solar panel generate DC it convert into AC that will charge ur phone in ckt u need this thing filter and amp ie the DC voltage come from solar panel 2 DC to AC convertor 3 AMP for AC 4 filter for AC and u are done....... fine ckt from google.....
- Q: So I'm trying to figure out what to ask for my birthday because its one of the few times I can get stuff for no reason, like stuff I don't normally go to the store to buy. (i dont go to the store to get much at all anyway).Anyway, I'm interested in solar panels and led and electronics and i was wondering if there is anything not over expensive that would be cool. Some things I'm interested in:solar, wind, water energyGadgets (multitools, swiss army knives)Vibram fivefingersdrawingmaking stuff (duct tape wallets, stuff out of altoids containers)basically technology and outdoors-gear stuffoh and im 6 turnin 7 male.
- solar panel is expensive, but small solar panel is not expensive, for example, 5w solar panel, solar light also not expensive led light also not expensive. i am not sure about other stuff that you said
- Q: does anybudy know about solar panels? plz reply me
- Solar panels, often connected to other panels to form an array will produce electricity when exposed to the sun. At this time solar panel is one of the fastest growing business in the world. Given the fact that most of our energy comes from fossil fuels (Oil, Natural Gas and Coal) and that those resources are getting used up and more expensive to get to, and given the fact that solar panels are getting cheaper and more efficient, eventually, the electricity produced by solar panels (or photovoltaic panels as they are sometime called, PV for short) will be cheaper than that of CO2 spewing electrical plants. Actually, it could be argued that if the coal, natural gas and oil industry was not subsidized so much by our governments, and if you demanded that the process of producing electricity from those sourced be as clean as PV, PV would be a cheaper source of electricity than fossil fuel already. Make sure to also look into the solar panels that produce hot water. SHW (Solar Hot Water) is very developed in country such as Israel, where the law demands that all new house be build with SHW systems. Those panels are very efficient at capturing the heat of the sun and produce hot water much cheaper over their life than using gas or electricity.
