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
All you need to do is to learn how to build solar panel to produce your own electrical energy through solar panels. These solar panels take and keep the energy from the sun and turn it into usable electrical energy that we can use every day in our ordinary lives. Generally, the majority of people that knew about solar panels think that they won't benefit from its use because they just work in sunny areas. That isn’t the case. In fact, the new generation of solar panels can produce a lot of electrical energy even on rainy weathers. Learning how to build solar panel is very easy: first they need to be installed (most of the time, on the roof of homes) and then they take the energy from the rays of sunshine and convert it from solar energy to electrical energy. Solar panels must be kept from shading, as shaded cells draw energy for themselves from other cells. Things you need to know: . Solar panels using monocrystalline cells have high conversion efficiency, and take up less space, but lack shade protection. 2. Solar panels using polycrystalline cells have even higher conversion efficiency, take up even less space, but still lack shade protection. 3. Solar panels using amorphous silicon cells have lower conversion efficiency, and take up more space, but do have shade protection. This can be especially important on a sailboat. Once you have determined the size and number of solar panels needed, you will be better able to determine where they will be placed. The best places depend on the roof's length and size of the panels. Take your time and think it through. The simple answer to how to build solar panel is none other than the sun. Select locations that will get maximum sunlight without shaded spots. In placing solar panels, consider the use of extra bars/braces to secure the panels. You obviously want them to remain stable.
Q: Which of these units determines how much electric energy a solar panel can generate?

Q: Photosynthesis is fairly inefficient, but efficient enough to power all life on earth.
One of the primary reasons solar cells are made of silicon is that the bandgap energy of silicon happens to be nearly equal to the energy of visible light, which is the major portion of energy emitted by the sun. Therefore, silicon is the ideal substance to fabricate solar cells with.
Q: Can solar panels be used in areas with high levels of vandalism?
Solar panels can be used in areas with high levels of vandalism, but additional precautions may need to be taken to protect them from potential damage.
Q: I am building a solar car for the energy wiz competition and I was wondering how I could possibly get my solar panel to shift sideways
having solar panels move like that on a mobile platform is inadvisable -- especially if there is a dynamic wind load resulting from the motion of the mobile platform. Even having a tilt mechanism is dubious at best. think of what limited marginal gain would be gained by mounting a small solar panel on the moon roof of a car. (ultimately, the best answer is to turn the car so that it's angle to the sun is optimal -- but the road/travel direction constraints are what ultimately prohibit that.) while there are ways to build sliding panels, the weight constraints would interfere with your weight/thrust ratios to the point of futility. if you really need that panel somewhere else, don't slide it out of the way, just buy another panel and mount it there. it's more expensive, but it's actually the cheapest solution in terms of design on a mobile platform.
Q: I am doing a science fair project on solar panels, and I need four solar panels to conduct the experiment. I would only need the solar panels for a week. What type of solar panel should I get?

Q: My Grandfather just purchased a cheap solar panel kit for his ranch that could not muster enough power to run his mini fridge.He has two 6 volt batteries running positive to negative and would like to add more batteries. Probably 2volt. How would he go about hooking up the other batteries and what kind of wire or coil should he use.Also, I saw on youtube a guy recommending a lead-acid battery from walmart for under $20. I was just going to go to ecology and just pick up some used batteries but I may be wrong.Any help for a first timer might help me and my gramps out will be appreciated.Thank you
If he is going to be running off batteries at night, he would be better off with traction batteries. Traction batteries are true deep cycle and can better withstand deep discharge. Golf cart batteries at Sam's Club (the other half of Walmart) are traction batteries. If your grandfather needs safe refrigeration, a mini fridge won't do it. A 0 fridge takes too much power to run off solar panels and most won't hold their cold very well if unplugged for long. I run a fridge off grid with hybrid deep cycle marine starting batteries. It's an Engel 40. The price has gone up over $00 since I bought mine. It's a real fridge with a compressor and freon 34a. But it runs on 2v dc or 0vac and only uses 36 watts running because of a special compressor design. It will freeze food if you turn the dial down to 2 out of 5. It can also deep freeze. I use mine to keep eggs, milk, cheese and fruit juice. Your grandfather would need 400 amp-hours name plate rating of batteries at 2v to run the Engel, and probably 00 real watts of panels to recharge his battery bank. The Harbor Freight 45 watt panel set only puts out 30 watts on a clear cool day. That won't do it.
Q: Can solar panels be installed on data centers or IT facilities?
Yes, solar panels can be installed on data centers or IT facilities. In fact, many data centers and IT facilities are increasingly adopting solar energy as a sustainable and cost-effective power source. Solar panels can be installed on rooftops or in open areas surrounding the facility to generate clean electricity and reduce their reliance on traditional grid power.
Q: Can solar panels be installed on greenhouses?
Yes, solar panels can be installed on greenhouses. In fact, it is a popular practice as it allows for the generation of renewable energy while utilizing the available space on the greenhouse roof. The solar panels can help offset the energy needs of the greenhouse and contribute to a more sustainable and environmentally-friendly operation.
Q: I am doing research for a project.Please reply soon! :)
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..
