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:_How many solar panels needed to light up a whole house?
this is according to the load, that is to say, how many electricity do you need in one day.
Q:Have a 40watt 20volt solar panel, how many watt of inverter do I need?
500 Watt Solar Panel
Q:cost of solar panels?
That's a rather low power for that size. Is it an old panel? Is it amorphous silicon, or crystalline? That should easily fetch $ per watt on craigslist. If I was buying a panel myself, I would probably get a more mainstream panel from a major internet vendor.
Q:Can I use a 250 watt solar panel to power a medium sized upright fridge?
How many watts does your fridge consume? Do you want it to work at night when the solar panels aren't doing anything? Probably not.
Q:Solar Panel load resistors?
Solar Panel Load
Q:why wont my solar panel make my dc motor work?
You didn't say how much power your panels can produce, or how much power (current x volts) the motors require. The panels must meet or exceed what the motor requires. You might need to get a very small motor and a little gearbox out of some other motorized toy, or at least a small pinion gear for the motor and a larger ring gear that can be attached to an axle (similar to how RC cars accomplish their drive train). A worm gear drive set might be even better if the motor / solar panel combination isn't very powerful - it'll go slowly, but some movement is better than no movement. If you put the panels in series, a 2 V motor should be the best match (again, only if its power requirements are small enough). If you want to try running the 3 volt motor off the panels, you might try paralleling them (make sure you get the polarity right or they'll try to kill each other) - you'll still be mis-matched, but if the motor requires less power than the 9/2/8 volt motor(s), it might work. If you have or can acquire a multi-meter, you'll be able to measure the voltages and currents and that will not only help you see what's going on, but adding some details might help others help you get this working.
Q:where can i get a small solar panel to power an outdoor water pump?
More okorder.com/... (... or search portable solar panel) And probably under a tree isn't a good placement for a solar panel. Good luck!
Q:where do you get little solar panels?
Thin-film solar panels are a great way to go if you're looking for small solar panels. Thin-film have the advantage of being lighter while a traditional crystalline panel is more efficient so it can produce more power with the same area. With the increasing efficiency of thin-film solar panels, however, they are quickly becoming an excellent option for portable power solutions. If you want crystalline panels instead of thin-film, the DURAlite line is a good example of a portable solar panel that uses regular polycrystalline solar cells. DURAlite panels come in 5, 0, or 20 Watts and they have a 0' cable with a 2-volt car-style socket plug.
Q:Any tips for protecting my solar panel from high winds?
Solar panels are a costly and significant investment. Therefore, protecting them from harm should be a top priority. Unfortunately, moisture and water are common ways for solar panels to become damaged or broken. Safekeeping solar panels from both of these threats is a simple, inexpensive procedure, and doing so might save the solar panel owner a bundle if carried out correctly Instructions : Set a thick strip of silicone between each cell when putting the solar panel together, in order to prevent moisture seepage. 2: Use Plexiglas instead of glass as the face of your solar panel. Plexiglas is less liable to break and therefore safe from hailstorms or accidents. 3: Glue adhesive silicone to each side of your solar panel(s), adding additional sealant and protection from water to your commodity. :)
