### The Solar Energy Plant Case Study Overview  
With the purpose of validating the developed functionalities, data from a case study related to a Solar Plant built in Charanka Park, in Gujarat, India, was used. This solar park comprises a total installed capacity of about 500 MWp, which makes it one of the largest of its kind in the world. The case study was conducted in the scope of the GloNet project. GloNet was developed to support highly customized, complex, and service-enhanced products, such as a power plant, pursuing collaboration with customers and some local suppliers. GloNet had the duration of 42 month and started in September 2011, involving several academic and industrial organizations (UNINOVA (Lisbon, Portugal), CAS (Karlsruhe, Germany), University of Amsterdam (Amsterdam, The Netherlands), iPLON (Schwabisch Hall, Germany), SKILL Estategia (Tomares, Spain), KOMIX (Praha, Czech Republic), Steinbeis (Stuttgart, Germany), PROLON (Albertslund, Denmark)).

The sector of solar energy is creating new business opportunities for small and medium organizations that can only reach larger markets if involved in CNOs. A solar energy plant requires several business services along its life-cycle and it is an example of a highly customized and complex product, involving a large variety of stakeholders in several distinct roles. Several business services may be added during the \"operation and maintenance phase\" of a solar plant in order to generate more value to the involved stakeholders, such as warranty enforcement, auditing, training services, monitoring, and preventive maintenance [19]. In most cases, in the solar plant industry, the market offers fragmented services, while clients demand integrated services, which requires support for collaboration among various stakeholders.  
The case study was performed in the context of a collaborative R&D project and performed partly in parallel with the development of the power plant. As such, part of the end-users' team accompanied all phases of the development of V-Align. On the other hand, software developers assisted the end-users in the pilot validation process.  
The GloNet pilot initiative proposes a move from traditional sub-contracting practices in the solar energy sector to the establishment of CNOs and (partially) remote service provision. During the life-cycle of a solar plant a variety of stakeholders are involved. Several of these stakeholders do many projects together, and thus they can be seen and organized as a VBE. The creation of proper profiles, including value systems modeling, is likely to facilitate partners' search and consortia creation for each new project.  
The stakeholders involved in our case study, which focuses mainly on the \"operation and maintenance phase\" of the solar plant and the co-creation of new services, are listed in Table 4. For confidentiality reasons the names of companies were anonymized.  
As shown in Figure 4, V-Align services require a set of information provided by the VBE Base Management subsystem. Therefore, during the set-up of the pilot experiment, the VBE Management subsystem was used to manage the Solar VBE profile and the profile of each VBE member. Each relevant stakeholder in this scenario was modeled including member's roles, values, profile data, competences, and rights. To illustrate distinct applications of the value system alignment in a collaborative context three main cases are explored:  
* Partners' Selection during consortium formation.
* Partner's Selection to replace a member in an existing consortium.
* Conflict Resolution between two partners during VBE operation.
