Solar water heating in Lebanon
Published 2006“…Simplified initial estimates indicate a payback period of 4–5 years while advanced mathematical models (RETScreen) indicate that the most advanced evacuated tube technology has a payback period of less than 9 years at current market prices. With decreasing cost per square meter of installed collectors, payback periods are expected to rapidly decrease. …”
