Q:Can I hook up a Solar Panel to a car battery? Does it matter the kind of car battery?
Those answers are partly correct. You cannot recharge two 2 volt batteries in series with a photovoltaic panel with an open circuit voltage of 8 volts. You possibly over charged your 7.5 AH battery with a 00 watt photovoltaic panel, which can supply 8 amps to the battery with unusually bright sun light = fully charged in one hour. More likely you did not charge the battery for a month or more which killed it. Also discharging below 2.6 volts shortens the life of the battery, or short circuiting the terminals even briefly. Yes a deep cycle sealed lead acid battery rated 2 AH is likely the best unless you buy a 00 amp hour marine battery which weighs about 80 pounds and will take at least two days of bright Sun to fully charge.
Q:Solar Battery System?
Deep Cycle Series batteries are designed to have a large amount of stored current discharged between charging sessions, with very heavy non-porous battery plates to withstand repeated major discharging and charging cycles (deep cycles). They are typically used where the battery is discharged to great extent and then recharged.
Q:How can I regulate current from a solar panel?
Lithium batteries do have special charging requirements. I would recommend that you use the 2 volt charger that came with them to keep them happy. Automotive power systems can have voltages as high as 4.5 volts when the engine is running so there's no need to limit the output of the panel to anything less than that. Check with the charger manufacturer to see what it will withstand. Some will work with systems up to 24 volts nominal (up to 29 volts actual) found in larger commercial vehicles such as trucks and busses. If your charger will work with both 2 and 24 volt systems you might not need anything extra to use the unregulated output of the panel. Otherwise I'd recommend a shunt regulator to clamp the output of the panel to no more than 4.5 volts. That way it would dissipate (waste) very little of the panel's power, and even that would only be during those rare times when the panel is producing maximum output. Such a device could be as simple as a high power zener diode, a low power zener coupled with a power transistor, or a precision shunt regulator such as a TL43 coupled with a power transistor. A more complex way would be a to use buck/boost regulator between the panel and your charger. You might gain a slight advantage under low light conditions when the panel isn't putting out much but the overall efficiency could end up worse than the simpler shunt regulator. Under optimum conditions, I would expect it to take a full day for a 3 watt (peak) panel to charge just one of your 35 Wh batteries. Charging an intermediate device such as the Sherpa 50 through its built in charger and then using it to charge your battery through yet another charger would severely cut your overall efficiency. Depending on how long you'll be gone, it might be far more practical, reliable, and economical to just carry (or find a way to be resupplied with) a few additional fully charged 35 Wh batteries. Don
Q:What direction do solar panels usually point?
I can't believe how many people posted wrong answers to this. Where are they looking? What are they thinking? In the northern hemisphere, solar panels are ALWAYS oriented due south. In the southern hemisphere, face them due north. I am typing on a computer that is running on a solar electric system that supplies my whole house. Been this way for years. So it works.
Q:What is so great about solar panels ?
Solar panels are eco friendly, they produce with out disturbing the enviroment. Instead of having to build dams and kill of species that have water homes we can use the sun as our energy source. im all for solar panels i hope this helps :)
Q:What is the best solar panel?
You have to decide which is more important to you, cost or efficiency. The most efficient solar panels that are commercially available cost more than twice as much per square foot than the cheapest ones. Ultimately, I believe that the cost per watt was actually better on the cheaper, least efficient panels, but then you need a lot of square footage in order to generate any substantial power. So it comes down to what you have more of, space or money. The new panels that collect a wider range of light are not currently available commercially, and when they are I am sure that they will be expensive. I have read the research but have not heard of anyone mass producing them yet.
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:Solar panel for macbook?
an significant questions is what voltage output is the skill grant? what's the wattage while the laptop has been used for hours and then related to the charger with the computing device off? this often is the skill attracted to can charge the batteries. Your answer desires to be waiting to take action skill score. additionally thinking the fashion of Apple skill plug the relationship thoughts would be few. fold-able image voltaic panels + small 2 volt battery + inverter + Apple skill grant or fold-able image voltaic panels + DC to DC regulator for particular Apple computing device DC voltage which contains the recommendations-blowing plug and polarity. Can a internet-e book or pill or clever-telephone meet your vacationing computing desires? all of them use much less skill and could require much less image voltaic kit.
Q:what do i have to study to install solar panels?
I say sure, I had a gadget put in some months in the past. I paid $6K and my application paid $0K. I ought to ruin even in approximately 6 years. The gadget is assured for 25 years, so i could have a minimum of 9 years of loose potential. I went from a invoice of around $two hundred per thirty days to below $20 interior the summertime. i will pay somewhat extra interior the iciness months because of the fact much less daytime, yet i don't use as plenty potential interior the iciness. each and each 3 hundred and sixty 5 days electrical energy is going up an elementary of five%, so on an identical time as my associates have an more suitable invoice each and each month, i'm going to be staying below $50 for a protracted time. Even with out the rebate i might have a ruin even time of roughly 0 years, nonetheless 5 years of loose potential.
Q:projector/solar panels help?
Do understand, that a solar panel is slow to pay for itself. Let's say your electric bill was $200 a month ($2400 a year). A solar system would cost perhaps $24,000 so you would actually have paid your first 0 years of electricity in advance when installing the panels. After that 0 years, you start to be ahead financially. It can still be a good idea, but it may not be the quick and cheap solution you were looking for.
