The Ministry of Energy from Chile is currently implementing the Public Solar Roofs Program (PTSP, from its Spanish acronym), which involves the installation of photovoltaic solar systems on roofs of public buildings. The main objective of PTSP is to contribute to the maturation of the photovoltaic market for self-consumption. PTSP will operate for the following three years and has a budget of 13 million US dollars. The Deutsche Gesellschaft für internationale Zusammenarbeit (GIZ) has been supporting in the planning, implementation and dissemination of PTSP as part of a project financed by the International Climate Initiative (IKI), through the Ministry of Environment of Germany.
The specific objectives of PTSP are:
- Stimulate the photovoltaic market through demand of PV systems from the state, which will be installed in public buildings.
- Provide information for free public access on costs and conditions of PV projects for self-consumption in Chile.
- Evaluate the current rules and procedures for self-consumption PV systems, according to Distributed Generation Law.
- Contribute to the reduction of electricity costs in public buildings.
The implementation of PTSP has recently started with one public tender, already awarded, for the installation of PV systems in three buildings in the city of Calama. The size of these installations ranges between 5 – 40 kWp.

Currently, there are five other tender processes undergoing for the following public buildings: Instituto Teletón of Santiago (70 kWp), Centro Cultural Gabriela Mistral, GAM (100 kWp), four projects at Copiapó (92 kWp) and seven projects at Parral I and II (185 kWp). Additional to these projects, approximately other ten tender processes will be launched during 2015.
It is important to mention that tender processes for the PTSP will continue for the next two years, including several Chilean cities. Also, the tender process allows the participation of international companies with robust experience.

Guides for building-owners and PV-Installation Companies
As a part of the Support to the Ministry of Energy in the Public Solar Roofs Programme, capacitation in terms of operation and maintenance was given to 45 users of photovoltaic installations established during the execution of the "PTSP Programme" .
During the capacitation two guides were provided which are detailed below.
PV BUILDING EVALUATION GUIDE.
Delivers the requirements for buildings to install a PV system, within the guide can be found how to select a stock building that requires a feasibility study and how to discard the ones that don’t, leading to an improvement in efficiency in searching for buildings with a PV installation potential.
OPERATION AND MAINTENANCE FOR PV SYSTEMS.
This guide takes in to consideration critical aspects of operation and maintenance, the guide delivers a tool that enables users to diagnose and evaluate the operation parameters from a PV inspection plan, allowing failure identification and troubleshooting in addition preventive maintained measures and the frequency of execution is explained.
