I want to use a 12v 5 watt solar batt charger to power my sirius boombox. How can I do this?

I am trying to find a way to power my sirius sattelite boom box using solar. I was thinking of using the 12v 5 watt panel offered on harborfreight.com (ITEM 41144-0VGA) with my boombox (SUBX2.) The only problem that I see is the input voltage on...


You would be best served by using the solar panel to charge up some NiCad batteries instead of directly connecting the panel to a boom box. (unless you need this for a demo on solar power)

The solar panel is not going to output a stead

Is a 5 Watt Solar Charger Enough to charge a Car Battery?

If I bought a random crap car battery would this be enough to charge it completly over time. Just putting it in the sun and hooking the red and black to the battery? Will this do that job. thanks

...


Do the math. Typical car battery is 70 amp hours (your battery will say). 1 watt = 1 volt x 1 amp. 70 amp hours @ 12 volts = 840 watt-hours.

So your 5-watt solar charger will take 168 hours of full-on sunlight to fully charge...

Why is a charge controller not necessary for a 5 watt solar panel?

My 5 watt solar panel car battery charger manual states that charge controller is not necessary for panels under 15 watts. I'm trying to understand the physics of why that's the case. Even if my panel is only putting out say 15 volts at 350mA...


A typical lead-acid battery can safely be "trickle charged" at C/100 rate, where C is the capacity (if you are talking car battery, that is about 50Amp-hours typical). C/100 for a 50Ah battery is 500mA, so 350mA won't hurt it. The...

how long will it take to charge a 3 amp battery with a .5 amp charger?

I have a 5 watt solar charger which converts to about .42 amps does this mean that the charger will store .42 amps of power each hour


Do you mean a 3 amp-hour battery? That's usually how batteries are rated. If your charger can really put 0.42 amps into the battery, then that's 3/0.42 = 7 hours. Make that 10 hours, because of the inefficiencies of charging.

I need a solar 12v charger with float?

I'm looking for an affordable way to charge a large 12v battery with solar power, but with a float so I don't boil it over and ruin the battery or worse. A year ago my brother and I nearly burned his house down with a tiny 0.5 watt solar charger that


Try, bass pro shops, cabelas, dicks sporting goods.

How do I convert a 24v solar charger to 12v?

This is a simple 5 watt solar panel that I am hooking up to a cigarette plug to charge my batteries on my truck that I don't drive much. The panel puts out 24 volts. How do I convert it to 12 volts?


Converters are shown in the link below.

However, most solar panels are 12 volts. I am thinking your have two panels connected in series to get 24 volts. It that is the case perhaps there is a way to wire them parallel instead of...

    • How much would cost for a Solar Panel system in Florida? | One ...

    by admin

    I live in Clermont, FL 34711. I’ve tried many solar panel calculators, etc. but i do not know if i’m doing something wrong, or what. My family wished me to research solar panels and find out what cost would be to power our home by solar. I been working on it for few hours tonight, but everything i find says we would pay anywhere between 40-80,000$ for a solar panel system to produce amount of energy we use! I though solar panel systems was getting so much better, but this is cost of a home in some areas!

    Hopefully i’m just doing something wrong. We use Sumter Electric Coop. According to electric bill, we use on avg about 55 KWH/Day. Or last month about 1600 KWH. (wrote caps, etc. as shown on bill to not confuse measurements given). Anyone who has any experience with solar panel systems can tell me if i’m wrong with my estimates of 40-80,000 cost to power our home? If so, i guess solar is way out of question for us, everything you hear on news, friends, etc. makes us think it would be like 5-10,000. Your number sounds correct, as despite what you see on the news the costs for solar are still quite high. Keep in mind that with economies of scale, the incentives and subsidies, and the ever rising price of fuel that the utilities are passing along to customers will make the cost of solar go that much lower. Push your local state representative to pass the Feed In Tariff measure that my research shows is working its way through the FL State Legislature, as that will bring down the cost of solar as well.
