- Q:What are solar panels?
- Solar panel is a generic term used to describe a device that collects and converts solar energy into electricity or heat. Photovoltaic module, used to generate electricity Solar thermal collector, used to generate heat Solar hot water panel, used to heat water, often in homes but i guess u mean the ones which generete electricity a photovoltaic module is a packaged interconnected assembly of photovoltaic cells, also known as solar cells. An installation of photovoltaic modules or panels is known as a photovoltaic array. Photovoltaic cells typically require protection from the environment. For cost and practicality reasons a number of cells are connected electrically and packaged in a photovoltaic module, while a collection of these modules that are mechanically fastened together, wired, and designed to be a field-installable unit are known as a photovoltaic panel or simply solar panel. A photovoltaic installation typically includes an array of photovoltaic modules or panels, an inverter, batteries (for off grid) and interconnected wiring.
- Q:Can solar panels be used on boats or RVs?
- Yes, solar panels can be used on boats or RVs. In fact, they are a popular and efficient way to generate electricity for these mobile applications.
- Q:why don't we take a cue from mother nature and make our soar panels like trees? thousands of leaves or needle (like a pine tree) instead of one big flat panel? I mean it seems to work pretty good for all the plants i see why would it not work for us. It would be aesthetically pleasing and with the right engineering wouldn't it make them not have to worry about tracking the sun? i already have some ideas about the process of making them just no available labratory.
- Because we and the trees are trying to solve a different problem. We want electricity, a tree wants light (and some heat) for photosynthesis. In getting the electricity we use Silicon for solar panels. (Sometimes Gallium Arsenide). And we exploit the same thing in Silicon that allows them to be computer chips. The fact that they conduct differently when voltage is applied. But for a solar panel that is done essentially in reverse. We GET a voltage difference (electricity) from shoving energy through it. Look up junction bias on google or yahoo for explanation. But the DESIGN problem is: You have to couple these panels together the right way - according to their bias. You can't string them up willy nilly. There is a pattern. And when one breaks in this pattern. (I mean when the actual panel cracks, which they do easily as they are brittle). It can change the overall bias. This can make even be worse than if it was removed, it can actually fight against the working ones. The efficiency is there in arranging them like a tree, but the practicality of maintenance would be daunting.
- Q:i am trying to get it to work on solar power They are outdoors and we dont feel like running a few hundred feet of power cables. Thanks and best answer will get 0 points.
- Only okorder /... Each battery will will need to be enclosed in a box from the weather to preserve it as well as the charge controllers. All this work can be done with success, but will be costly if that's what you want, and want it done right. You have no short cuts around this unless you want to damage your cameras? I still say it would be much easier to run conduit under ground for your power supply to each camera, and it would cost less money and time.
- Q:What are the different applications for solar panels for residential use? How many should I purchase if the avg panel produces 80 watts .
- Solar panels Will give you Free hot water Heating Power to your home You need to learn how to harness it with truck batteries Ask at solar shops about wattage
- Q:I have a building company in UK and am interested in becoming a solar panel installation contractor
- Every single solar system will have to be put on every roof by people. Of course much of the processes used installation are designed to be as pain free and trouble free (and therefore as inexpensive) as possible but in a typical British street of semi detached houses built in the 930s you could find as many different plumbing and heating systems as there are houses, so you will never be able to remove the human installation element.
- Q:Can solar panels be used in developing countries?
- Yes, solar panels can be used in developing countries. In fact, they can be a highly effective and sustainable solution for providing electricity in areas where access to energy is limited. Solar panels are easy to install, require minimal maintenance, and can harness the abundant sunlight available in these regions. Additionally, solar energy can help reduce reliance on expensive and polluting fossil fuels, improve access to electricity for schools, hospitals, and homes, and contribute to the overall development of these countries.
- Q:If a solar panel is a .5kW system, what length of time is it putting out that much power? Every hour?
- I think it refers to the maximum power it is capable of. Of course, it won't really have this output because it's energy output (kWh) is dependent on it's energy input...
- Q:We want make solar panel for our home use. but we have no any right idea how we can make it. we want to make it with cheap prices.we also want to know the proper size of solar panel.where we can take help about making a solar panel
- How to Make a Solar Panel – Everything You are Going to Need There are several things you’re going to need when making a homemade solar panel, some of the main components include: Solar Cells Wood Plate Soldering Iron Solder Tabbing Don’t worry; special tools are not required for this DIY ‘solar panel’ project, and you will probably have everything you need laying around the garage. Now let’s go over the recommended materials for a basic solar system: Plexiglas Solar Cells Screws Lumber Jones Plug Wire Diode Caulk Silicon Material
- Q:Can solar panels be used in areas with high levels of pollution from industrial emissions?
- Yes, solar panels can still be used in areas with high levels of pollution from industrial emissions. While pollution can have a slight impact on the overall efficiency of solar panels, they can still generate electricity even under such conditions. However, it is important to regularly clean the panels to ensure maximum performance and efficiency. Additionally, investing in advanced solar panel technologies, such as anti-soiling coatings, can help mitigate the impact of pollution and maintain their effectiveness in polluted areas.
