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:solar panels and wind power help?
If you are planning on purchasing a solar or wind system installed etc. I believe it will take considerable time to pay off. If however, you are even remotely handy, building a 3kw wind generator is well within the realm of possibility. I have a smaller windmill that I built myself using some ingenuity and some parts bought on OKorder. That windmill and 4 2 v deep cycle batteries run myu 9 share well 24 hours a day. I spent about $250 to build the windmill, tower, and buy used batteries, and have saved an average of $60/month for months now. This really isn't rocket science either, I'm a freakin' cook =) for more on the subject of diy wind and solar projects see the resource below.
Q:How many LED's can I hook up to my mini-solar panel?
Typically LED's run off low voltage and 20mA or so of power (it depends what kind of led you have). That being said if one of your solar panels only provides 22mA of power then your circuit would have to be a series circuit for you to connect more than one. In a series circuit the current supplied of 22mA will go through each LED whereas a parallel circuit the current would be divided for each subsequential led. So in your case i can see you getting away with 3 or so led's before the voltage drop across each led will cause the voltage to be insufficient enough to drive anymore. Keep in mind the LED's will turn on but the first one will be bright then next one not as bright and so on. If you opted out and bought a solar panel with 200mA and 4V you could wire the led's in parallel and get 0 led's to turn on with the same brightness or intensity. Hoped that helped!
Q:how long do roof solar panels last?
Who okorder.com/... That suggests that the power the panel output will degrade a little less than % per year. We've had ours up for 5 years now, and I haven't noticed a steady degradation pattern. But the yearly weather is so variable, it's hard to see a pattern. The 2nd year's production was actually higher than the first. It could just be clearer skies or colder temperatures, who knows.
Q:Connect Power Outlet to Solar Panel?
The least expensive way would be to get a 500 W or preferably a higher rated UPS. The higher the rating, the more robust the inverter. You can get two year old ones cheap because most people don't realize that it's just a $2 battery that goes bad every two years. Get some Car batteries in parallel to build up more capacity. Deep cycle marine batteries or golf cart batteries are best. Connect the Solar Panel to the batteries via a FET diode, assuming your solar cells are wired to produce 2 V or better power (you probably would want at least 8 V), this is to charge the batteries when the sun is shining. A little bit of analog circuitry magic can create a current limiter based on a Darlington pair type layout. Connect the batteries to the rest of the UPS (don't plug it into the wall) and you can run 0 V 60 Hz AC devices off it's outlets. You may want to snip the wire going to the speaker so you won't hear the alarm. There's no way you could sync this to the grid so don't even try a grid tie in and the inverter in the UPS is only intended to run for 0 to 20 minutes so it may burn out however we've run UPS inverters constantly for months before when we needed a cheap power converter to change AC power frequencies before.
Q:How do Solar Panels work, and how it can generate electricity?
Solar okorder.com under products that are sorted by watts per area. Also go to wikipedia to get more detailed information on solar cells.
Q:how much money do solar panels cost?
Hi, One or two new windmills may not cost you as much I believe. Just my suggestion anyway.
Q:Can you get energy at night from solar panels?
There okorder.com/
Q:Increase Solar Panel Efficiency?
If you have a way to keep silicon panels cool, that really helps. On a hot summer day, our array was down 20% in production. I sprayed a hose to wash the panels, and for a few minutes, the power spiked to 20% ABOVE normal. The usual thing to do is mount the panels exposed to the wind if you can, or at least 8 off the roof otherwise. A few lucky souls with access to free stream water on their property have been known to use water cooling under their panels.
Q:Why only Photo-Voltaic solar panels?
you completely nailed it!! speaking about large buildings, it would benefit one to do a little more research. my company just installed a 640 collecter system on a million sq foot building. it consists of a absorption chiller (which uses no coolant, just water a silica gel beds, runs of the power of its controller, thats it) 27,000 gallon tank. chiller feeds 2 rotation units and 2 large office spaces for heat and cool. payback expected at less than 5 years. we will expand this system another 200 collectors. residential installs, if tax credits used, achieve 5-7 year payback pending domestic hot water only or dhw and space heating. thermal collectors actually produce more energy than pv panels do, therefore more bang for your buck, also as i hope you all know, pv has around 25% eff, thermal has 95%. also to say the tech part is gone, we use flowmeters that calculate carbon offsets, energy saved, money saved etc...all located in a wireless monitor for the consumer to enjoy.
