  • I see another youtuber testing this unit which I’ve been using for a few months. The programmable load control feature is great. The controller uses your solar panels as a photosensor to turn your lighting or other loads to go on/off. A few minutes after dark, the controller will switch on the load automatically. You can program your12v lights to be on from 1 to 13 hours. The controller is only 10amps and goes by other names also. The unit is $30 on Ebay. In life, sometimes you overpaid, get a bargain and sometimes a real steal. Well, $30 for this unit is well worth it for me.

Irrigation system prices are based on system size and can range from $5,000 to $40,000. We have proudly installed our systems worldwide!

    A few things we need to know:
    1. Flow rate: How many gallons per minute, hour, or day?
    2. What system pressure will you require?
    3. Your location?
    4. Head height: The height required to raise the water?
    5. Do you need a well pump or a surface pump?
    6. What length of pipe does the water need to travel?
