How reliable are solar pumps?
Solar pumps are the reliability gold standard for moving water. The design of a solar pump minimises moving parts. By minimising moving parts wear is localised to just a few components and breakdowns become very infrequent. This means that a solar pump, once set up correctly, can run for many years with minimal intervention required on your behalf. This is not to say that they require zero maintenance: it pays to periodically check your solar pump components for wear and replace them before a breakdown occurs.
