- Q:Im looking at making a self build iPad solar panel charger, Is it possible to get a small solar panel, a battery to hold charge and then a USB output? nothing fancy, just power in and power out?
- Lithium okorder / For USB power, there are some references you should seek out from the websites of Fairchild, On Semiconductor, Texas Instruments, National Semiconductor, just to name a few. There are others, and if your IPad has the control circuitry for the accurate charging of their batteries, and you just need the USB port to have the right power available, a high compliance regulator such as an LM7805 should do just fine. Spec sheets for that regulator are available through the above mentioned manufacturers websites as well.
- Q:I recently got into solar panels, I have little background in electronics but I have done a little electrical work in the past and just want to make a small 36 cell panel to power a 2v battery that would run my a small tv (9 inch) and PS3 for a few hours every night. I have been looking up on how to do it before I get in over my head and I have a few questions.... After you solder all of the cells together then what? Do you hook all of the rows of cells together somehow? Can you connect them straight to a battery? After you hook to the battery do you hook up a power inverter to get the 2 AC plugs that would be needed? Thanks in advance for any help....
- I'll add a few comments to Teelo's It may not be good to connect the assembled solar cells directly to the battery. When there is no sun I think it will drain the battery. I'm pretty sure all circuits I have seen have a reverse polarity diode in series. (unless Teelo knows for sure). Hmmm Reminds me that I have some bare solar cell elements from when Motorola was making them. I used some to power a small radio controlled car. I do know that all good applications have a regulator to make sure the charging is done properly
- Q:Also, where can solar panels be purchased in the Binghamton/Liberty/Jeffersonville area? Home Depot has some on their website I would like to see them in a store before purchasing or ordering them.
- Go to your state's department of revenue and enter the solar panel thing in the site search box and follow the thread to exactly what is in place in the here and now. Things seem to change on a daily basis any more.
- Q:i have to do a science fair project and thought it would be cool to make a solar powered vw bus. i have 2 6volt solar panels to power a dc motor that works off of 9v 2v or 8v. i also bought a 2nd motor because the first wasnt workin for us. this one is a 3v motor. ive had them in the sun but they wont work. please help, thanks
- A 2V battery designed for a current max of 200mA, can turn on a 2W lamp. If you want to turn on a 2V 200Watt lamp, you need a bigger battery capable of providing 6 amps!! Similarly the solar panel you have can produce a voltage, but when connected to a motor, the voltage might drop to much lesser value!! So apart from voltage you also need to know current taken by motor. Further, motors have a habit of not starting, but once prodded (mechanically rotate the shaft with hand), they may run. If you are in that border area, give a turn to the motor and see.
- Q:Lower solar panel/wind turbine prices allow wider applications, hence a great help to a greener mother earth!
- “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:Can solar panels be used in cold climates?
- Yes, solar panels can be used in cold climates. While the efficiency of solar panels may slightly decrease in colder temperatures, they can still generate electricity even in freezing conditions. In fact, solar panels can even benefit from the reflection of sunlight off snow, which can increase their output. Additionally, advancements in technology and the use of anti-reflective coatings have improved the performance of solar panels in cold climates.
- Q:Can solar panels be installed on a greenhouse?
- Yes, solar panels can be installed on a greenhouse. In fact, it is a common practice to install solar panels on greenhouses to harness the sunlight for both electricity generation and to provide supplemental lighting for the plants inside. This not only helps in reducing energy costs but also promotes sustainable and eco-friendly practices in agriculture.
- Q:Mono-crystalline or poly-crystalline solar panel?
- All solar photovoltaics drop in efficiencies with higher temperatures but it isn't the 45+ C you have to worry about but rather the heat from the sunlight striking the panels. There are hybrid systems which passes water in pipes attached to the back of the solar panels to cool the panels and preheat the water for solar thermal collectors. The difference between mono-crystalline and poly-crystalline are that mono-crystalline are more efficient and more costly to make.
- Q:I have made a 5v dc 52watt solar panel and I going to be trying to charger 4 2v dc 55ah batteries. I get about 6 hours of sun on my panel. Spec below, is that a big enough panel to charge the batteries???I have 30 3x6 solar cells wired together Cell Specifications: (Watts): .75 Wp (Amps): 3.5 Imax (Volts): 0.5 V max which is where I got my 5g 52watt max (if math is wrong plz tell me) The Battery type: 2Volt 55.0ah NB Sealed Lead Acid Battery. I am using a mppt solar charger.
- I don't think so, but if it did, it would take a very long time. You need enough wattage or amps to push the power in the battery and 3w may not be enough. You would be better off with a small 2v battery, maybe the type they use for emergency lights. I would use a sealed battery for this type of setup because car batteries are designed for heavy charging with alternators from 60 amps and up.
- Q:Can solar panels be used in areas with high levels of shade?
- Solar panels can still be used in areas with high levels of shade, but their efficiency and energy production may be significantly reduced.
