Q:How to charge a Battery with Home Electricity and Solar Panel together?
No, don't connect the panel directly to the battery. You need to isolate the solar panel charging output from the AC-powered charger. A couple of high-current diodes arranged with their anodes connected to the charging sources in the positive supply line will allow either the charger or the solar panel to lift the voltage high enough to charge the battery, albeit with about 0.6 volts dropped across the diode. Both cathode ends would be connected to the battery. This arrangement allows a positive current to flow from either or both charging sources at the same time, although in practice, one will generally be higher than the other. Also, if the AC charger's voltage is significantly higher than the solar panel, the charger may always charge the battery. You would need to regulate its output to be slightly lower than the solar panel when it's near it's minimum useful operating voltage. (note that the 0.6 forward bias voltage on the diode might prevent the solar panel from completely charging the battery if it has any voltage regulation on its output)
Q:How much power does a solar panel generate?
That site tells you somewhat about the cost of solar panels and their MAXIMUM output. Now some who have these panels claim output, in daily terms, 8 times as great as maximum output, which says they are counting on 8 hours of effective sunlight. In California Desert that is sound. You will discover that Ontario Power grid is planning for 3 hours to 4 hours of maximum output . Based on that 3 to 4 hours of maximum output, it would take close to 20 years to recover your cost at the price Ontario pays for solar power. The deal locks you in so that you can not get more money as electricity prices go up, and do not lose if electricity prices go down over that 20 years.
Q:How do you charge a battery with a solar panel?
48 volts is rather uncomfortable. I would be inclined to modify the panel by cutting traces to give me a number of 5 volt sets. Most PV cells output about 700 mV, but check to see what yours does. Measure one cell, or count the number of cells and divide into the panel voltage. If you work with the 48 volt output, you are throwing 70% of the output away. The classic method of charging a lead/acid battery is to use the 0 hour rate...a 200 AH battery is charged at 20 amps. However if the charge is to be near continuous during daylight, I think I would go a little lower...say 5 amps in order to be kind to the battery. I note that your panel has a 6 amp output, so when you modify it, it should be able to deliver about 8 amps. A useful trick is to use car headlamp bulbs in series. The filament has a high positive thermal coefficient of resistance, and tends to act as a current regulator. In this case, I would use two dual filament bulbs with their filaments in parallel, arranged in series.
Q:Are solar panels a good idea in Seattle Wa?
Are solar panels a good thing to do for the environment? - Yes. Can you recoup the cost your investment in the solar cells/panels in any reasonable amount of time in Seattle? - most likely - not. I know it's been a miserable spring in Seattle, but, I think we got 3 sunny days last month. With the number of cloudy/rainy days here, solar will only really benefit you in June, July, August and September. There are two kinds of solar panels - electric or water based. The electrics - photovoltaics - are costly to purchase and it's difficult to store the electricity once you make it. A water heater type solar panel initially cost less and can provide some benefit even on partly cloudy days. I have even seen instructions on how to build your own (if you are frugal and handy) I just do not think it's worthwhile in Seattle - if it was Denver or Phoenix we were talking about - then it would be a different story.
Q:How effective are solar panels?
Well, the maximum amount of energy you can receive with 00 percent efficiency is kilowatt per square meter. This is the energy that hits the Earth's surface. The best commercially available panels are 20-30 percent efficient. Cutting edge technology has gotten this percentage up to 50 percent, but you can't buy these for your home. If you're curious about efficiency, check out a panel's dimensions, find the area in square meters, and use that along with its Watts (divide by 000 to get kilowatts) to get your answer.
Q:what materials would you use and how would you construct solar panels enough to run a household?
Silica based solar cells are not the kind of thing you whomp up in you basement. Here are a couple ideas for solar systems you can build and install yourself. Take a 4 x 8 sheet of /2 inch plywood. Frame sides with 2 x 4's. Screw tin cans in a staggered row (checker board) pattern inside frame. The more cans the more heat you get so place them nearly touching. Paint cans and entire assembly flat black. Cover top with glass, plexiglass (best) or heavy mill clear plastic (cheapest)Place on roof. Drill 3-4 inch holes in opposing sides. Run pipe or tubing into house. Attach to small low speed fan. The black paint will absorb sunlight and heat. The air moving through box will carry heat into house. It's a cheap efficient way to help heat your home. You can vary size and shape of box to fit your roof. If you use more than one box, hook them up in series. More boxes mean more surface area means more heat. To heat water. Take a steel tank. A car gas tank works well. It is galvanized so it won't rust, is cheap, and easily available at any auto salvage yard. But you will have to flush in throughly to remove gasoline odor. A steel 55 gallon drum is easier to work with but may cost more. Paint exterior of tank flat black. Weld/glue/clamp water pipes to tank. Place on ground in area that gets lots of sunlight. Attach water supply to tank and route discharge pipe to house or appliance. Black painted steel absorbs heat from sun light and heats water. In spring and fall you get warm to hot water. In summer you get scalding hot water and in winter you get cold to luke warm water. Both of these solar powered systems are seasonal and their output varies according to location and climate, but they are very inexpensive and easy to build and provide FREE heat and/or hot water for many years with little or no maintainence.
Q:where to face solar panels?
The following links is a sun angle calculator which I find very helpful during my days of doing project about solar panel. The calculator will give you the accurate location of the sun. Solar panel work best when it is directly facing the sun. All you have to do is key in your location details and it will provide you with two most important details: azimuth angle and altitude angle. Azimuth angle is the East angle where the Sun is relative to the South while altitude angle is the tilt angle of the solar panel throughout the day. By using these two angles, you will maximize your exposure of solar panels. However, if you are experiencing rainy or cloudy days, horizontally mounted solar panels is the most efficient.
Q:How Do Solar Panels Work?
The most important parts of a solar cell are the semiconductor layers, this is where the electron current is created. There are a number of different materials available for making these semiconducting layers, and each has benefits and drawbacks. Unfortunately, there is no one ideal material for all types of cells and applications. In addition to the semiconducting materials, solar cells consist of a top metallic grid or other electrical contact to collect electrons from the semiconductor and transfer them to the external load, and a back contact layer to complete the electrical circuit. Then, on top of the complete cell is typically a glass cover or other type of transparent encapsulant to seal the cell and keep weather out, and a antireflective coating to keep the cell from reflecting the light back away from the cell. A typical solar cell consists of a cover glass, a anti-reflective layer, a front contact to allow the electrons to enter a circuit and a back contact to allow them to complete the circuit, and the semiconductor layers where the electrons begin to complete there voyages! The solar panels, in order to generate power, are using the method of screen-printing, a technique developed for printing fabrics, paper and to produce plastic, glass and metal solar cells. The basic materials of a photovoltaic cell (solar cell) are inexpensive. The homemade solar cells have about /4 of the efficiency of commercial silicon solar cells, which turn 0-20 per cent of light energy into electricity. But, being cheap to produce, they can make up the loss in quantity what they lack in quality.
Q:Good Idea To Install A Solar Power Energy On A Restaurant?
not really 2 little 3 very little 4 depends on size of unit 5 depends on how much electricty you use 6 many
Q:What type of wires should i use for a solar panel?
Most epoxy is not very conductive. I would go with solder.
