Sunforce 123 watt solar panel 1.)Have also used for numerous 3 - 5 day stays in California and Arizona in Feb - Apr.
I purchased one of these about 8 months ago, along with the Sunforce digital 30-A controller and Duracell 800-w inverter to use on our motorhome when in campgrounds with no hookups or when boondocking.
Sunforce 39110 123-Watt High-Efficiency Polycrystalline Solar Panel with Sharp Module (Misc.Provided plenty of battery charge for lighting, furnace fans, laptop, TV, etc for week long trip to Oregon outback in September.I built a portable/adjustable stand that takes only a few minutes to set up.Works great!Really nice to have the extra freedom, and to not run the noisy/smelly generator.
It provides the power you need, while helping you save money and protect the environment.This panel is ideal for cabins, recreational vehicles, remote power, back-up power, and 12-Volt battery charging.


2.)I use less than 25% of my water quota every month, and as a result, don't pay higher rates for the water I do use.I am fudging the math ever so slightly because, obviously 123 does not equal 120) So if your house pulls 50 amps of power all the time (yeah right - only if you are running air conditioning all the time with 4 TVs on and your freezer with the door open) you would need 50 panels (working at 100% rating ha ha ha) to power your house during the day.A watt is a watt so you can add up the wattage that you use in your home and double it (safety margin and you can't expect your panels to pump out 100% power all the time.I wouldn't count on powering your house directly from just two panels unless you have a way to store the power like batteries.That translates to 1 amp (assuming 100% efficiency) at 120 volts.Normally they are both charging two marine deep-cycle batteries hooked in parallel to a 2KW (square wave) inverter which stays on all the time.I also power several items directly from the batteries 12 Volt taps, including cell phone chargers and the like designed to run on 12 volts.Now account for the fact that you will probably not get 100% out of your panels for numerous reasons, account for the transmission loss, general inefficiencies in conversion to AC, and general, 50% engineer's markup insurance, you would probably want between 75 and 100 panels to meet your electrical needs.123 watts =1 amp x 120 volts.Just remember that your house would probably only pull more than 50 amps at peak times and if you also use battery backup for storage, not only will you also have power at night, but the juice from the batteries will help buffer any surges from starting up your A/C, hot tub, washing machine, table saw, or other unreasonable industrial machinery you might be playing with in your garage.When the marine cells are fully charged, I also switch one controller to GEL CELL and charge some gel cells I use to pump shower water onto my lawn.These go into separate, independent 30 amp Sunforce controllers.I purchased one and was so happy with it, that I bought a second one.The formulas, if you care, are: P=I x E where P is the power in watts, I is the current in amps, and E is the electrical voltage soooooo.Since these solar panels can put out nearly 10 amps each, they make quick work of charging two marine batteries.I use it to power mostly lights at night in my bedroom, but occasionally my vacuum, laptop, and such.123 watts = 10(ish) amps x 12 volts So you can get up to 10 amps at approximately 12 volts.So I have two on my balcony leaning against the house facing southwest (in Los Angeles.We have water restrictions here in Los Angeles, and I see no sense it just letting mine go down the drain.

(some customer reviews)
1. It doesn't get much simplier than that.Two wires to the battery and two wires to the solar panel.Worked flawlessly out of the box.
2. Since it works as advertised, will use it until the circuit board corrodes and fails.I use it to regulate a 10 watt solar panel that maintains the charge on a gate opener battery.Would have rather been told in the product description that it was not weather proof.This charge controller works as any voltage regulator does.Had to seal the case where the front & back meet.
 
3.This review is from: Sunforce 7 Amp Charge Controller (Misc.Improvements would be using screw-on terminals (instead of short wires), and it could use larger LEDs.The unit performs as advertised and, mercifully, has input polarity reversal protection.
 
4. I would have put five stars, but I have not owned it long enough to be certain that it will last.Easy to install, good value.This review is from: Sunforce 7 Amp Charge Controller (Misc.This is the second solar charge controller that I have bought by Sunforce.The other one is a size bigger and has worked well for a year, this one is about four weeks old and is working well so far.Yellow LED indicates charging while green LED indicates the battery is charged.
