Q:solar panels and batteries?
If it pulls 9 amps continuously, that's 08 watts/hour or about 2.5 kwh/day. If it only pulls half that (does it cycle?) it's about .2 kwh/day. You only want to drain a lead-acid battery 50% or so, so you'll want a 5 or 2.5 kwh battery pack. A typical setup for the 5 kwh would be two L-6 batteries in series, and for the 2.5 kwh you could use 2 T-05 batteries in series. This does not account for days of cloud. If you regularly have cloudy days, size the battery pack for two or three days of use with no input (2-3 x the sizes given above). To charge them, you typically want panels that will charge your battery at least 5% of its capacity per hour (C/20). For 2 volt nominal panels that's 0 amps for the T-05 or 20 amps for the L-6 batteries. It's good to have more than that for battery life (it cuts down on what's called stratification), so you'll want probably 50-200 watts of panels for the T-05 and 300-400 for the L-6. You'll also need a charge controller. Peltier coolers are very inefficient. You'll save money by using a regular mini-fridge and an inverter. Most mini-fridges only draw 50 watts or so, so you're talking 600 watt-hours for a 50% duty cycle. This means two T-05 batteries will give you two days of use and you'll only need 20-50 watts of panel. DK
Q:Solar Panel Current=Battery Current+Load Current?
I am not sure about your question ? If your Q is, what is the solar panels current output, it is 8.73A regardless of the load. If the Q is, How much extra current is available in this circuit, the answer is 3.58A ( 8.73 - 4.32-.83= 3.58)
Q:What is the best low power alternative for TV set, to use as screen for dvd player, with a 30watt solar panel?
Do what we do when power is cut (although we have very reliable power - we loose as much as 2 hours a year), is go Amish. That is go without powered technology. Now, for you, you need more than a solar panel (and likely more than 30W, but that is a start) - you need a battery or set of batteries to store the collected power. 20Ah might do. You need an inverter to power things. For that, likely a 300W will do. For a TV, go shopping, and look at the labels on the back of the TVs. I just bought a 24 TV rated at 40W. If you get a 9 LED TV, it may be likely you can run that directly from battery, for many have separate DC brick supplies. With those, you can make a cable to power it directly from a 2V or so battery, if the supply can make 2 to 5V. Depending on your provider, you may be able to get a mini-decoder which uses a separate brick or wall supply, which means the decoder likely can be directly battery powered. Such a decoder may draw less than 20W.
Q:How may solar panels/wind turbines may be made affordable?
“the living feed the dead” -- may have actually lucked into the answer. The government does assist the petroleum industry and it funded the research that gave us nuclear power. If alternative energy is going to work, it may require intervention by the government in terms of access to land (imminent domain) and to the transmission grid. Alternative energy companies are stuck because of their own paranoia (of industrial espionage) and because they are being gouged by land owners. A single wind turbine on your land can net you $70,000 a year (plus a 0% increase per year for inflation), forever. Then there is the cost of the corridor to access the grid. Solar companies are trying to purchase land like drunken sailors – and landowners in areas where solar can be most effective (e.g., the American Southwest) are hip to what is going own. So when acquisition agents call to purchase land, owners are demanding outrageous prices (say $5,000/acre for land that is worth about $00/acre, otherwise). Then there is the fact that nobody (rich or poor) wants one in their backyard, not to mention the various PAVE (People Against Virtually Everything) groups who protest stuff just because they can. ===== A Modest Proposal -- <<0% inflation rate is an extremely high You are, of course, right. Nevertheless, that is what some Wind Energy companies are offering land owners as part of the lease agreement for placing turbines on their land. I agree it's outrageous, but I'm an environmental consultant for several Wind companies and I know what they are offering. As a side note. They were initally so lame (and this is related to their general paranoia) that they cut deals to place the turbines before they secured corridor access to substations. When they subsequently approached the land owners (the same ones with the turbines on their land) about the corridor, they were held hostage for outrageous money - as in millions of dollars - because by then the land owners had them over a barrel.
Q:Solar Panel System companies at the swapmeet?
Hard to say. Solar panels are becoming more common these days. May want to ask if the vendor is licensed and bonded contractor (if he's doing installation as well as panel sales). Find out the name of the equipment that this guy is selling (panels and other hardware) and do a search. For that matter, get the guys name and do a search on it to see he pops up elsewhere.
Q:Can a solar panel be used as a NiCd cordless tool battery charger?
Your 5W solar panel has to put out about 5 volts or higher to charge a 2 volt battery. 5 watts at 5 volts is only 0.3 amps, which is only enough to handle the internal leakage inside a large battery, plus a bit. If you have a 00 amp-hour battery, that panel would take 300 hours of bright sunlight to charge it. But I do agree that it will keep the truck battery charged as long as it gets sun. Make sure you put a diode in series between the panel and the battery to prevent the battery from discharging through the panel when the sun goes behind a cloud. I'd be worried that if you charged the 8 volt battery frequently, the panel would not be able to replace the lost charge, and your 2 volt battery would wind up discharged. That 8 volt battery is .2 amp-hrs (if I got the correct one). That is 27 watt-hours. Allowing for losses, you car battery will have to deliver over 30 watt hours to charge it. Your solar panel will take over 6 hours of bright sun to make up that difference. That is over 24 hours this time of year. So if you recharged it more than once every 2 days, you will lose charge in the truck battery. .
Q:What makes solar panels Inneficient?
Science. The best solar panels we have only get like 22% of the sunlight for conversion into energy. That is simply the best they know how to make with current technology. And for that your talking about a mobile panel that tracks the sun as it moves at the equator. A solar panel in say Canada is lucky to get 0% even on a sunny day. But even if a solar panel got 00% efficiency, it's still not a lot. Sunlight is too diffuse to be a good power source, and you'd need to cover lots of ground to get power. Worse, you can only get power when the sun is out during the day. So for power at night you'd need a battery, or another source of power. The 'newest' idea is to capture sunlight to make 'lasers' that boil water, to turn turbines and make electricity. They cost way more then they are worth right now though...
Q:Solar panel setup?
You have to keep the polarity straight. Red is positive + Black is negative - I don't know how much amperage you are drawing, or how many amps the solar panel puts out. This charge controller is a device I am unfamiliar with- What does it say on it? how many volts? how many amps?
Q:Does a 50W solar panel generate 540kWh?
your first question: Does a 50W solar panel generate 540kWh? 540 kW-hr / 50W = 3600 hours it would take that long for the panel to generate that amount of energy. your second question is confused, as you both stipulate the number of hours at 6 hours per day, and you try to solve for the number of hours. 000 x 50w = 50 kW 50 kW x 6 hr/day x 30 day/mo = 27000 kW-hr/mo = 27 MW-hr/mo that is the amount of energy generated. That is nowhere close to 88240 kWh or 88 MW-hr. I would take 7 times more solar panels to generate that much energy. .
Q:Electricity question about solar panels?
Watts = Volts * Amps Your heater needs at least 500 watts of AC power. The solar panel only produces about 200 watts of power ( 24volts * 8amps). Not enough to run the heater. Also, the solar panel produces DC current, not the AC current that the heater needs. However, if you had solar panel that produced enough power (watts), you could buy a transformer to turn the panel's DC output into the required AC output. But that doesn't seem like a real cost-effective plan.
