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.

Replace costly and polluting gas/diesel engines with solar energy systems for irrigation! From 10 gpm to Over 1000 GPM!! Star Power Systems offers Solar irrigation for farming or water pumping, fluid transfer, waste water management, industrial, commercial, residential systems. Never use diesel or gasoline again, save thousands of dollars!!Website: http://www.starpowersolar.co, Email: starpowersolar@yahoo.com, 516-994-5897. 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?
