solar panel to power 12v battery&pump

[MarineLiner]

We had discussed similar case last time.
It's about watering a farm and Mike suggest: better if do the pumping in good sunlight hour only, meant no battery necessary.
Please try to find it, click the "pump" tag and you'll see all pump posts.

No offense guy but if he cannot afford a 50 to 100 watt panel, how can he afford a 180 to 200 watt panel to run the 12 volt 15 amp pump?

Since I can most likely rule out a solar panel due to the expense, can anyone suggest a battery that i should look for? Does the battery still need to be "deep cycle" if i am not using a solar charger?

Ok you are giving up just a bit too quick here. I went back and read the whole thread and picked up where you live in Central NC. Your worse case is December with 3.6 Sun Hours. Do you even need the water in December. If not what months will you need the water?

OK just using December worse case data and 1 hour per day use it will take a 75 watt solar panel. Eliminate December and January watering and you would need a 65 watt panel.

As for the battery question Solar application does not matter, your use is a deep cycle application regardless where the power for the charger comes from. You need a good 12 volt 75 Amp Hour Battery. Those can be had for about $60 to $90 depending on brand and where you buy it from. They are easy to find in that size, even Walmart has them in that size.

OK I think you can get by with a 50 watt solar panel and those cost anywhere from $50 used up to $100 new, an 7 to 10 amp charge controller for around $35 to $50, and a 12 volt 75 AH battery for $75. Total bill around $200, shop carefully and I think slightly less.

During the later Spring, all Summer and early fall no problem running the pump a full hour each day. In the cold months no problem running 30 to 40 minutes per day. Heck in colder weather you should not need much water anyway will you?

Thank you. i had no idea i could possibly do the project for that price. I only need the pump to run approx 30 minutes a day during april- september.

i was looking at an Exide deep cell for approx 175 dollars. I just do not know where to look for the panel and other parts since this is new to me. Thanks.
