- Q: Where can I find good instructions to build a cheap solar panel on my own?
- Lowe's has some good plans, i built one using a 4'x8' sheet of foam in a box 6 tall cut grooves in the foam paint it with Black latex paint put a inlet and outlet at opposite ends of the box 4 in dia cover the box with a clear sheet of plastic put a screen over the hole in the top a duct in the bottom with a fan hooked to a temp switch , [hint a fan limit switch out of an old furnace works ] run the fan duct in to the house

- Q: Can solar panels be used for powering outdoor lighting?
- Yes, solar panels can be used to power outdoor lighting. Solar panels convert sunlight into electricity, which can be stored in batteries and used to power outdoor lights during nighttime. This allows for cost-effective and environmentally friendly outdoor lighting solutions.
- Q: (For a project)I know they are made of silicon, but I want to EVERYTHING they are made of. Ex Metal (What kind)Please tell me everything used from their production to the finished projectThank you
- Solar panels are slabs of semi-conductor metal. Technically speaking, they are a slab of silicon semi-conductor doped or added with impurities to make it a better conductor. Solar panels could also be made of Gallium Arsenide which is a semi-conductor metal exclusively used in photo-voltaic cells.The silicon slabs are polished and glossed before doping. After processing, for protection, a thin glass layer is embossed on the solar cells slab. Silicon also is shiny and reflects about 35% of sunlight. Hence, an anti-reflective coating is usually applied over the slabs to reduce the amount of sunlight lost.
- Q: How about using Solar Panals to provide the electrical power to separate the H2 from the O? H2 would be fed into the engines carburator like a gas/air mixture ratio, but H2/air mixture ratio instead. How would you control the exact measurements?
- Currently solar panels are rated at about 5 percent efficiency. That means that about 85 percent of the solar energy that is falling on it, is wasted. Electrolysis is also about 67 percent efficient. So the TOTAL amount of solar energy you would have converted into hydrogen is 67 percent of 5 percent. Using my calculator that comes out to: about 0 percent total efficiency. About 90 percent of your solar energy gets wasted in the process. A better alternative to solar panels would be solar powered sterling generators. Sterling engines are EXTERNAL COMBUSTION engines, like the old fashioned steam engine, and can be run off any heat source - including the sun. Heat from the sun is focused using parabolic mirrors, and the efficiency of a sterling engine / generator combination is rated at about 30 percent. Your TOTAL efficiency - both solar sterling and electrolysis combined - would be around 20 percent. If you are dead set on using hydrogen? Even though there are better alternatives? Such as alcohol? Then I would suggest storing it in titanium dioxide pellets. This way you can store the hydrogen, without it being in danger of exploding. You can ALSO ram a hydrogen container like this into a solid brick wall. Once again? Without fear of an explosion. Numerous studies have been conducted on this. As for controlling the exact measurements? Nothing in the air-fuel ratio of a car - - or the timing - which you are also going to have to change - needs to be exact. A good enough approximation will do. As for how you get your measurements? You need to compare the density of gasoline vapor with hydrogen gas. A comparison of the molecular weight of gasoline - - as compared to the molecular weight of hydrogen - should get you started in the right direction for this.
- Q: I need to prepare solar panels for using in home needs electricity purpose. Can anyone could help me to know much more about it.
- It's possible to make a DIY homemade solar or wind power turbine to power your home, house, water pump, irrigation system and much more. You don't need to buy expensive wind turbine generator equipment. Trust me these wind power generator equipment cost so much that you could spend years saving to buy a very small unit. I live in a very windy and remote area in Kenya; Africa where it might be another 3 decades before the national power grid finally gets to our horizon. I was about to buy such equipment when I stumbled on a do it yourself manual online that had colorful illustrations of how to make a homemade wind turbine for as low as $200. Compare this to a small turbine unit that goes for no less than $ 3000 and you see what I mean when I say you are better off making one at home.
- Q: How much space is required to install solar panels?
- The amount of space required to install solar panels varies depending on several factors, including the size and capacity of the panels, the energy needs of the property, and the available sunlight. On average, a typical residential solar panel system requires about 100-400 square feet of roof space per kilowatt of installed capacity. However, ground-mounted systems can also be installed if there is enough space available on the property. It is recommended to consult with a solar installer to assess the specific space requirements for a particular installation.
- Q: How many solar panels have ah?
- However, crystalline silicon (monocrystalline silicon and polysilicon) in the weak light is basically no current generation, amorphous silicon weak light type (in low light energy is rarely). So a comprehensive view, it is appropriate to use monocrystalline silicon or polycrystalline silicon solar cell materials. Second, the choice of solar cells 1, we buy solar cells, the focus is on the power of solar cells, in general, the solar panel power is proportional to the area of ??solar chips.
- Q: How many solar panels do you need on your house to power your heater in winter?
- As a solar installer, I'd love to give you a simple answer but I can't. Most solar contractors offer a free solar evaluation where they will tell you how much energy they can generate given your site conditions, what it would cost, and how long the payback would be. Rather than a bunch of inexperienced people giving you a bunch of hypotheticals, I think this would be the best option.
