====Maintenance====
This configuration (an array, a pump, but no batteries) allows the design of systems that need no operator attention. The pump will start and stop automatically – all that is required is periodic maintenance involving the occasional cleaning of the panels and the pump site.
 
====Security aspects====
Theft and vandalism of solar photovoltaic modules poses perhaps the greatest threat to solar PV systems. To reduce this risk, it is imperative for the community to be fully involved in any PV installation project and to have complete ownership upon completion. This ownership should include the responsibility for maintenance, operation and replacement costs of damaged or stolen components.
 
Theft prevention normally includes fencing. For fences to be effective they should be 2 metres high, with barbed wire, and have gates with proper locks. Communities may also decide to employ a night guard and allocate money from their budget for security staff salaries.
