Low Maintenance Costs and Long-term Reliability PV cells were originally developed for use in space, where repair is extremely expensive, if not impossible. PV still powers nearly every satellite circling the earth because it operates reliably for long periods of time with virtually no maintenance. Once installed our solar power systems requires little or no maintenance (especially if no batteries are used), and will provide electricity cleanly and quietly for 25 to 40 years. Our solar panels carry a 25-year manufacturer warranty on their production.
