Abstract

Reliable local cost information is essential for residential rooftop photovoltaic (PV) planning. However, Indonesian studies commonly rely on a single assumed capital cost or international benchmarks. This exploratory original research article develops a transparent market-derived benchmark using a single-date, two-platform cross-sectional observation of 94 solar-product listings collected from Shopee Indonesia and Blibli on 23 June 2026. The primary residential grid-connected analytical sample consisted of six rooftop modules rated at least 500 Wp, 15 on-grid string inverters, five residential on-grid packages, and eight relevant balance-of-system items. Prices were classified by application and technology, normalized by rated capacity, and summarized using robust descriptive statistics. An exploratory log-log model was applied to on-grid inverter prices within the observed marketplace sample. The median online listed prices were IDR 3,967/Wp for rooftop modules, IDR 3.900 million/kW for on-grid string inverters, and IDR 16.583 million/kWp for residential on-grid packages. The estimated inverter capacity-price elasticity was 0.460, suggesting a capacity-related pricing effect within the observed inverter listings rather than a nationally representative pricing relationship. The screened listings showed the online visibility of conventional and N-type modules, string and microinverters, hybrid products, LiFePO4 batteries, and both on-grid and off-grid packages. However, package scope, shipping, warranty, transaction prices, and installation information were frequently incomplete. The results show that online marketplaces can support timely PV cost intelligence and technology-visibility analysis when products are screened into homogeneous categories, but listed component and package prices should not be interpreted as actual transaction prices, installed turnkey costs, or nationally representative Indonesian PV market benchmarks.
