In-field performance of a polycrystalline versus a thin-film solar PV plant in Southeast Asia


By Philip Napier-Moore, Heads the Regional Renewable Power Team, Mott MacDonald; Setta Verojporn, Electrical and Renewable Energy Engineer, Mott MacDonald

This paper considers the relative technical and economic performance, for selected sites in Southeast Asia, of PV plants using crystalline and thin-film PV module technology. Technical performance estimates are based on a forensic analysis of in-field data for two grid-connected PV installations in Thailand using polycrystalline and thin-film PV modules. These two case studies help to validate the performance simulation approach for the other considered countries with similar environmental conditions. The case studies show that Mott MacDonald’s yield analysis approach demonstrates acceptable accuracy for energy yield assessment in a grid-connected PV plant, at least under the observed environmental conditions, which are most relevant to Southeast Asia plants with polycrystalline and thin-film PV modules installed. The findings presented in this paper are relevant to project developers and investors who have an interest in selecting solar PV technologies for Southeast Asian regional conditions.

The period of ‘profitless prosperity’ in the PV industry is finally at an end. Throughout 2013, despite continued economic woes, the PV industry has continued to expand and finally become a global industry. Market forecasts indicating that the sector could reach its next 100GW milestone in just the next two years suggest the industry is on the cusp of another period of strong growth. All the signs confirm this is the case, with utilization rates at their highest level since 2010, companies reporting full order books well into next year and the first tentative announcements of factory capacity expansions making the headlines.
