Abstract

The growing integration of solar photovoltaic (PV) systems in Thailand is primarily driven by declining system costs and incentive schemes. This trend has concurrently led to the challenge of “invisible” PV installations. These installations fall into two categories: (1) exceeding the contracted specification, and (2) unnotified behind-the-meter connections that result in unintended meter reversal (‘meter-run-backward’). This study examines the financial evaluation of invisible PV installations by comparing their profitability with that of business-as-usual (BAU) projects. The analysis focuses on both centralized and residential PV systems under various incentive schemes, including Net Billing and Net Energy Metering.
