Answer: 
It will but the more batteries you have the longer it will take for charging. The formula is : The inverter determine how big a load you can power. The battery(s) determine how long you can run that load. And the panel(s) determine how long it takes to recharge the system after use.

Answer: 
It should? The variables are how much sunlight you receive. 2 - 12V batteries is safe, 3 may take longer than 7-8 hours. With that said, if they are not discharged over 50% of capacity, you should be good to go. Hope this helps?

Thank you for your interest in Grape Solar panels. There are a number of factors that play into whether a 100-watt panel will meet your expectations but in short, yes, a single GS-STAR-100W can charge 12 volt batteries if they are wired in parallel to create a 12 volt battery bank. For higher voltage battery banks you will need multiple 100-watt panels wired in series.
While it depends upon your exact geographic location and orientation of the panel, a single 100 watt panel will produce roughly 25-AmpHours per day. Depending upon the size of your batteries and how much power you plan on using per day, you may need multiple panels to keep your batteries topped off.
In order to prevent damage to the battery you should have a charge controller between it and your panel. If you don't have a charge controller already, you may wish to look at our 100-series kits which come with 100-watt panels, charge controllers, wires and, in most cases, inverters to get you up and running quickly.

It is not the Square footage but the Kilo Watt Hours you use.

If you are doing an off grid system, and have Propane or wood for heat, cooking and hot water, the only real loads left are refrigeration, lighting (CFL or LED)Exhaust fans, microwave oven, Flat screen TV and electronics. For those, you would need 200 to 250 Kilo watt hours per month so let's calculate 250 Kilo Watt hours. 250,000 watt hours / 30 days = 6,033 Watt hours per day. Since one 100 watt panel will produce an average of 450 Watt hours per day 6,033 / 450 = about 14 - 100 watt panels and with 2 Amp hours per watt for Battery overnight usage, you would need 2,800 Amp hours of deep cycle battery storage. (24 - 115 Amp hour Batteries# You would also need 3 - 500 watt Charge controlers. Since i also have air conditioning, I use 3,200 watts of Solar panels and 6,400 amp hours of Deep Cycle 12 volt batteries and 7- 500 watt charge controlers. You will not be able to Air condition more than Two rooms with this small system that I use and when the days are shorter in the winter, you get about 1/2 the power but you also do not need air conditioning.
If you are "On-Grid" look at your utility meter bill for the Kilowatt hours used each month and divide buy 13.5 #.450X30) to get the number of panels you would need to be equivilant to what you use. Then you would need Grid tie Inverters or Micro inverters and it would be best to consult a licenced Solar installer to get you through the permit prosses from your city.

Answer: 
You will need one 100 amp hour deep cycle marine battery and a charge controler along with a 1500 watt running/3000 watt peak 12 volt to 120 volt inverter to get the motor running on the gate for a 110 Volt 1/2 hp motor. The 100 watt solar panel just recharges the battery. Motor start up uses the most current and your inverter will need to be sized to that start up current.

Answer: 
Paired with a charge controller and a deep cycle battery, this panel should produce approx. 300 watt-hours per average day (more in summer, less in winter). Compare this to the daily watt-hour load of the pump (watts times hours per day of use) to get an idea of how many pumps a single panel can power - keep in mind it depends, to a large degree, on how many hours per day the pump runs.

To properly size an off-grid system or battery backup system, we would need to know the following:
1. Your estimated daily power usage in watt-hours (we need exact daily watt-hour numbers from customers because many standard appliances and devices have widely variable power consumptions)
2. Maximum inverter wattage and voltage required – what is the most power, in watts, that the inverter will need to produce, and are you using any 220 volt appliances?
3. Location or zip code of where the panels will be mounted.
4. Months of the year that the system will be needed (winter, summer, year-round, etc.)

Answer: 
You will need to look at the specifications of the pumps to see how many amps they draw. At peak performances, these panels will about put about six amps, so if the selected pumps are rated at one amp, that would means, you can have six under IDEA conditions. I would suggest a maximum of four per panel to be safe. Make sure to use a 12 volt solar charger and 12 volts pumps.

Whenever you are running 12 volt vibration type pumps continuousely, you have to use a 12 Volt battery along with the 18 volt solar panel, charge controler and the "included" power supply along with a 12 Volt to 120 volt AC inverter.. The solar panel will produce about 80% of the current you need and the battery will keep the voltage within the range you need to run them. 5 and 10 watt fountain pumps are just that. so you could run 8 - 10 watt pumps or 16 - 5 watt pumps or a mixture that adds up to 80 watts.while the sun is out after 9 am in the morning and up untill 1 hour before sunset. For 120 volt pumps, I use a 400 watt inverter off of the battery/ solar panel and a time clock to turn mine on at 9:00 AM and off at 6:00 PM. A solar panel alone will run some 24 volt DC "motor type" pumps once they have enough sunlight to equal the current needed by the pump. The more pumps you have, the longer it will take for the panels to reach that current output. Having Two panels, with one facing East toward the sunrise, at a 45 degree angle and one facing west at a 45 degree angle will allow your pumps to come on sooner, just after sunrise and run right up untill sunset. Remember that inverters, that change 12 volts to 120 volts will eat about 5% of the rated full current of the inverter. ( ie a 400 watt inverter will eat up to 20 watts of power just to run ). Be carfull with those AC pump power supplies that say 12 volt output because they need 120 volts AC stepped down to 12 volts AC to run and will burn up if you try to apply 12 volts DC to the pump without it's AC power supply. If your Pumps say 12 Volts DC or 24 Volts DC, you will not need the 12 Volt to 120 Volt inverter and you can just add up the rated current on the nameplate up to 80 watts per panel used. If you are running less than 40 watts of 12 volt pumps, you might consider 2 - Grape 50 Watt panels facing one east and the other west as I described above if you have no other plans to add landscape lighting or more pumps later. My system runs both Pumps and lanscape lighting so I use 2 - grape 100 watt panels and 2 100 amp hour deep cycle marine/RV batteries on 5 -10 watt fountain pumps and 20 watts of LED landscape lighting and a solar charge controler with a nightime lighting curcuit built in and a 2 pole/double throw 12 volt relay that when not powered, runs the inverter that runs the 12 volt AC pumps through my timeclock relay and when powered at night , runs the landscape lights. The solar charge controler has low voltage limits that will turn off the lights when the voltage drops below my selected set point so that when the sun comes up, the remaining voltage will be enough to power the pumps when my time clock says 9:00 AM. If the inverter does not have enough voltage, it will not come on so on cloudy days, you may not run untill after noon and your landscape lights may turn off after only a few hours. Read Less

Rated 5.0 out of 5.0 by Great portable solar panel I was looking for a solar panel that wasn't large and heavy but produced a decent amount of power. This one is exactly that. It's easy to transport and move around. I now charge my electric tractor batteries in the field with little effort. The panel is well made with top quality materials. I would definitely recommend it. May 18, 2016
Rated 5.0 out of 5.0 by Purchase of (3) three Grape solar panels. I am in the process of building an Off Grid Micro cabin (12x16 feet). I have not installed the panels as of yet. But that will not be a problem. Got these three panels when they were on sale. Was an "In the store" online purchase. Sales assistant was great in assisting with the online order. The panels at 100 watt each and will be sufficient to power up LED lights, a 12 volt auto am/fm radio/cassette player... and with the appropriate size inverter, and deep cycles batteries....will power a 4.0 foot studio type refrigerator. Very satisfied with the products and would recommend Grape solar panels to anyone providing you do a little research to get what you need for your situation. May 17, 2016
Rated 3.0 out of 5.0 by good quality product, inadequate packaging Ordered 5 of these while they were on sale. While I haven't placed them in service yet, they appear similar in quality and workmanship as as other panels I have purchased. In my opinion, the manufacturer's packaging is not adequate for shipping via UPS. Of the 5 panels, one panel was damaged in transit and has to be returned. While I feel Home Depot will do the right thing and replace it, it is still a hassle to have to deal with the whole return process. June 7, 2016
