Many experts now advocate the use of LCOE over cost-per-Watt, which is often used to express the cost of a PV system.
Cost-per-Watt (or $/Watt) only describes the purchase price for the initial power capacity for a solar panel; it does not express the overall cost of system ownership.
According to many experts, LCOE is a much better performance metric that reflects true system performance and, therefore, true investment returns. LCOE points us toward grid parity as it enables the best cost/performance decisions.
DuPont™ Solamet® metallization pastes can help lower the overall LCOE, by increasing module power output, using less material and improving adhesion, enhancing solderability and reliability.
