How long do the systems last?
Our systems solar modules have a power output warranty of 25 years and give very little trouble. They have no moving parts to wear out. Our brush style pumps averaged 3 to 5 years of run time before service was needed. If the water level shut off is used to shut the pump off when the tank is full, hours of run time are saved on the motor extending pump life. The motors in the brush style pumps had a 5,000 hour rating. The new Brushless Motor Pumps have a 20,000 hour rating on the motors increasing the average life expectancy tremendously. We have customers who have had our pumps working for over 10 years without maintenance. Water quality and a proper installation are key factors in how long the pumps will last. If there is no weep hole installed in a well where freezing temps can occur, the pump can be ruined. If the pumps are placed in terribly sandy or dirty wells premature wear is inevitable.
What are the maintenance costs?
The pumps are rebuild-able so depending on the wear on the pump parts and the style of pump you have you could spend between $300-$500 to rebuild one.
What about hail on the panels?
We always recommend that you add these systems to your farm and ranch insurance policy. In most cases it doesn't cost more than $20 per year, but consult with you agent for exact figures. In over 20 years of selling these systems and with thousands of systems in the field, we only know of a handful of panels broken to hail. They have weathered many hail storms and are extremely durable. The insurance is a great idea however.
