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 can I make a sun tracker for a solar panel?
tbls0 has a good idea for the tracker, but let's take this one step farther. A clock motor large enough to move a solar panel, unless it is a very small one is going to be large, and expensive. Use the timer motor, as suggested, but attach a slotted disk to it, with a light source on one side, and a detector on the other side. As each slot comes up and allows light to pass through, this creates a one shot pulse which is used to cause a stepper motor to move position to keep the panel aimed at the sun. At the end of the panel travel for the end of the day, a switch could be set to close, bypassing the step control to put the motor into full constant speed reverse, this causing the panel to swing back to the morning position. The whole affair gets it's start up call by means of a light detector, similar to those used to turn lights off at sun up. The control would, of course be set to turn the system on to track the sun during the day. While some digital control is going to be needed, the system would not need a computer to run it.
Q:What about solar panels?
This is a site that can help you estimate the size and number of panels that will power what you intend to provide for. There are plenty of sites selling the panels, so compare prices. Also, check whether your state is offering the rebate like the state of CA is and what the restrictions, terms and conditions are. Even with the rebates they are very costly, so be certain to calculate the pay off period for your application to see whether it is a cost efficient option for your energy usage.
Q:What is the cost of Solar Panels?
Hard to answer, it really varies. A rooftop electric panel will typically be about 200 watts or so, and an installation would have many of them. Here's an example: Suntech STP 200 These Modules Provide: 200 Watts VOC 33.40V VMP 26.20V ISC 8.2amp IMP 7.63amp Width Height Deep 39 58 3/8 3/8 $488.00
Q:what colour can solar panels be ?
Ours are all silver - we have them on a canal boat and on our house roof for water heating. I've not seen them in any other colour, but that doesn't mean they don't exist.
Q:How much Silver do we need for Solar Panels?
Some research has shown that small amounts of silver can improve the efficiency of solar panels. But this appears to be in the research stage and applies to the the thin film solar cells. Some solar panels makes use silver as the wiring in kind of a screen printing process, but you don't need to use silver, you can use copper or aluminum using different techniques instead. Generally the metal used is in small amounts and not a majority of the cost of the solar panel.
Q:2- 390 W Solar Panel's Series or Parallel?
Q:Solar Panel Help Please!?
I will give you the tools to answer your own question. Here is the solar resource map: rredc.nrel.gov/solar/old_data/nsr... Use it to look up the hours of peak equivalent sunlight per day in your area. For example, let's say it's 5 hours / day. Then per year you get 365 x 5 = 825 hours of sun Your panel is 20 watts, or 0.2 kW So the energy produced per year is 825 x .2 = 383 kWh You'll have to use the proper numbers for your own area, of course. Anyway, you can take that 383 kWh and determine how much it would cost at local electric rates. Never know, on some islands, it's $.00 per kWh. Check with your local electric company for rates.
Q:I NEED HELP WITH MY SOLAR PANEL SYSTEM PLEASE HELP?
I think you need to take some basic courses on electricity. Usually, 8 volt solar panels are required to charge 2 volt batteries. The voltages of photovoltaic cells are set by the material they are made of, only current changes. If you hook up a 2 V solar panel to a 2 V battery, no current will flow, nothing would get charged. You would need some elaborate DC to DC voltage converters to charge a 2 V battery from 2 V solar panels. Solar panels can be connected in parallel or in series, as you've made the mistake of buying 2 V solar panel, you would have to wire them in series and have a charge controller that could limit the voltage of the charge. Did it ever occur to you that two 5 watt solar panels would not be able to provide the power needed by a 400 watt inverter? You're just running off your battery with your set up. Solar power is expensive power, you can not have solar without burning a hole in your wallet.
Q:solar panels and wind power help?
A lot depends on location. If you haven't seen other solar panels or wind turbines in your general region, that could be a clue that the area is not really that good for them. The best thing to do is look in the phone book under solar or wind and see if there are local installers. In the event that your area is suitable for both, I think you should choose one or the other, to avoid complexity and extra cost in the system. We have solar electric. It really requires long-term thinking to get such a system, because the up-front costs are large. It will be 5, 0, maybe even 5 years' worth of electric bills that you pay up-front, in a suitable location. After the solar is installed, your electric bills will be lower or near zero, but it's only after that 5-5 years has passed that you actually start saving financially. A professional installer can run the analysis and you can see if the numbers make sense to you.
