Project ID: 683928

Periodic Reporting for period 1 - REPHLECT (Recovering Europe´s PHotovoltaics LEadership through high Concentration Technology)

Reporting period: 2015-08-01 to 2016-07-31

Summary of the context and overall objectives of the project

The People’s Republic of China path towards cheap silicon PV modules has been successful up to now. Impressive cost reductions have been achieved by Chinese manufacturers in the last decade. This to a big extent through state-funded massive investments in capacity scale-up, devised to attend unsustainable subsidized markets worldwide, this frequently resulting in oversupply and dumping.

In despite of this solar PV electricity only accounts for less than 1% of the global electricity supply and a maximum penetration of 5% in the next 10 yrs. is envisioned by prospective agencies (Bloomberg New Energy Outlook, 2015).

We firmly believe that an innovative combination of advanced High Concentration PV (HCPV) technology and a close to the end-market business model, has the potential to become a paradigm changer holding the promise to achieve the ultimate pervasiveness of large scale solar electricity.

With its proven 18% learning rate at a systems level vs. 12% of silicon-based PV and 11% of CSP (Concentrated Solar Thermal), HCPV is currently the solar technology with the highest cost reduction potential. Furthermore, its conversion efficiency increases 1% every year with cells expected to reach 50% before 2020. This together with its best-in-class temperature coefficient and its dual axis tracking, already provides up to three times more energy per unit surface than silicon based PV in the highly sun-irradiated regions of the world.

Additionally, BSQ Solar’s technology has been especially conceived for high tolerance assembly processes, both at the module and sun tracker level. This, joined to the much lesser use of semiconductor solar cells in HCPV, allows the transfer of up to 80% of its production close to the end markets, and opens the path to a compelling and truly global alternative to the present Chinese-centered way of doing PV, presenting superior advantages in terms of, involved logistics, local job creation, and plant construction and maintenance.

To enable this vision, BSQ Solar is developing a modular low cost module assembly line, as well as the methodology for the optimal implementation of local manufacturing and supply chain, both at the module and sun tracker level. These manufacturing capabilities will be developed by the so-called Satellite Production Centers (SPCs). On the other hand, the most CAPEX demanding part, the HCPV compact receivers, containing encapsulated multi-junction high-efficiency cells and its optical coupling stage, will be produced by BSQ Solar and supplied to the SPC’s network.

Ultimately, the REPHLECT business model seeks to replicate the white box paradigm which introduced the absolute commoditization of the computer hardware industry, by leveraging the solar electricity technology providing the fastest learning curve and the best-fit solution for the solar-rich regions of the world.

REPHLECT has therefore the following main objectives:

- To provide solar electricity generation with the most advanced technology, and the highest cost-reduction potential, available on the market today and to help it spread, in order to achieve scale production which can in turn result in realizing the reduction of its costs.

- Market entry and scaling up is to be done through a proposed new manufacturing paradigm that can pave the way for EU to recover manufacturing PV leadership.

Short term specific objectives towards the goals above stated are:

- Develop a manufacturing line for HCPV receivers (RML: Receiver Manufacturing Line) and an assembly line for HCPV modules (MAL: Module Assembly Line)

- Demonstrate the migration of MAL to a first pilot Satellite Production Center (SPC).

- Validation of the SPC-based production scheme through the construction and performance assessment of an HCPV Pilot Power Plant (PPP) in the country of the first pilot SPC.

- Obtainment of Quality Certificates for the novel 1000X HCPV module and its tracking system.

- Obtainment of Quality Certificates regarding the RML and MAL and its processes.

- Obtainment of a Product Technical Due Diligence (PTDD) issued by a leading lender’s technical advisor.

- Develop a commercial strategy to reach Tier 1-2 Markets with in-depth and continuous analysis of market needs, requirement and regulations.

- To disseminate project results and techniques as widely as possible within several communities of potential stakeholders to facilitate highly efficient market replication actions.

- To implement the relevant guidelines that will be provided to potential business partner and policy decision makers for introduction and application of REPHLECT.

- To provide training to professional end-users on the REPHLECT manufacturing model.

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

After 1 year of running, the REPHLECT project has achieved the following results:

- First versions of the MAL and RML have been developed and built. Production of sample units of receiver blocks and modules have been carried out with them, these being successful quality-wise.

- Technology transfer and construction of first SPC hosting a MAL is in progress in cooperation with Al Akhawayn University in Ifrane (Morocco). Hosting facilities identified and training of local personnel has begun.

- Product design-for-manufacturing review carried out, along with supply chain shift towards EU. New HCPV system design oriented towards the rooftop PV market is proposed as spearhead to break into the market.

- In collaboration with Tecnalia Ventures an exploitation and commercialization plan and a preliminary business plan is being carried out

- Numerous project dissemination actions carried out. Sponsoring and attendance to conferences and workshops. Social media activity and periodic Newsletter. Pitch events.

- Obtainment of quality certificates, for both product (IEC standards) and processes (ISO management systems) are in progress

- Technology/Manufacturing Life Cycle Assessment carried out in a Northern African scenario.

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

In the last five years the European Union has lost most of its formerly dominant PV industrial fabric. China through strong political and financial support, has seized leadership both of the industry and the market. If the EU wants to recover its previous leadership, it cannot imitate the Chinese way, not having the sociopolitical structures for it. Instead, disruptive technologies and game changing ways of doing business should be the basis for regeneration actions.

High Concentration Photovoltaics is today a fully mature technology that has achieved an 85% cost reduction in the last 5 years with no specific market support. Much of this progress of HCPV has been achieved thanks to entrepreneurial and research efforts in the EU. REPHLECT is based on the strong belief that HCPV can offer Europe and the world a new way of dealing with PV.

Due to its much lesser use of semiconductor devices than Si-based PV and to BSQ's HCPV technology counting on system components that allow high-tolerance local manufacturing, REPHLECT proposes and demonstrates the migration of assembly lines to so-called Satellite Production Centers (SPCs) located in highly irradiated areas, to produce its HCPV systems close to the natural end markets. The most IP sensitive and CAPEX demanding part, the HCPV receivers, will be produced at BSQ’s factories in Europe and supplied to the SPC’s network. Up to 80% of the end product can be assembled in these SPCs, that can be built at four times less CAPEX in a than silicon PV equivalent. Production scaling is then achieved through a wide network of SPCs that closely follow demand – lean manufacturing – and are strategically located close to the demand centers, taking advantage of local content bonuses and avoiding import penalties. SPCs, would not only host assembly operations, but also taking advantage of their proximity to the end-customer, would have its own local sales force, installation crews and equipment and post-sales support. In this way local SPCs would also take the role of retailer stores.

In other words, REPHLECT intends to replicate the white box paradigm which introduced the ultimate commoditization of the computer hardware industry, and challenge in this way the present PV industry model based on the massive use of semiconductor material and the huge centralized upscaling in state-controlled economies.
