I have used one of those systems to charge batteries and use off grid. We have a well with a solar pump on it..works great. Just for watering critters ya know. If i remember right You can charge up to 5or 6 batteries with that 45 watt cell. But you have to have a blocking diode for night..or it will discharge.To go to all solar energy on my place it would cost in the neighborhood of 25,000 bucks.. and work well for 25 yrs or more. But if the price of electricity continues to go up as Nobama wants it to..you will save money in the long run..
