Sensus Energy has received, in partnership with Energy Research Center of the Netherlands (ECN) and Teledyne Dalsa (TDA), a grant from the Dutch Ministry of Economic affairs in the framework of the Top Consortium program “Solar Energy in the Built Environment” (TKI ZEGO). The subsidy is granted for the execution of a joint project on the development and validation of Sensus Energy’s Intelligent Solar Electronics for solar systems, to be used in the built environment.

Sensus Energy has developed novel energy harvesting technology that allows modular built and parallel connected solar systems, comprising small cell clusters of 2 up to 10 cells. This new approach in solar system architecture allows optimal system performance, even under suboptimal conditions, and results in up to 20% higher output for solar systems that are partial or temporarily shaded, soiled or even partly malfunctioning.

Rolf Huiberts, CEO of the company: ‘In our philosophy, modularity is key. We approach solar systems in an integral way and match all the individual system components into an optimal performing system around our solar harvesting technology. Our modular approach creates many new design opportunities for solar products, like aesthetic solar integrated construction materials, such as solar roof-tiles or façade elements.

It is a clear international trend to reduce the energy footprint of buildings. Solar energy provides an important solution contributing to energy efficient buildings. Currently, however, solar systems can only be used in non-shaded roofs, the so-called A-locations. In case solar systems are installed on roofs, which are temporarily or partially subject to shading (B or C locations), their performance drops dramatically. Modular solar systems designed by Sensus Energy provide an answer to this draw back. In addition to optimal system output, the Sensus approach enables strong system simplifications, resulting in competing system prices, even in this highly competitive industry.

The main scope of the project is the further development of the Sensus harvester and the independent external validation of the technology. The Energy Research Center of the Netherlands will be responsible for the economic and the technical validation. Sensus Energy, together with chip designer Teledyne DALSA, will further develop the harvester.

‘This project gives an enormous boost to realize the goals as defined in our roadmap. We consider this project as a critical stepping-stone to realize esthetic building integrated solar (BIPV) systems.’ Huiberts said. Wilma Eerenstein, coordinator of the PV Applications & Smart Modules development work at ECN, stated : ‘In the solar industry we see a clear movement towards modularity. Sensus Energy’s unique harvesting solution anticipates to this trend and we are keen to work with them on this topic.’ Clemens Mensink, CTO at Teledyne Dalsa: ‘We have been working with Sensus Energy for a few years now and are impressed by the performance of their harvester. We support Sensus to design, produce and characterize the harvesting electronics. We are glad to be part of this project since we see the potential of their harvester in the solar industry.’

About Energy research Center of the Netherlands (ECN)

ECN is a foundation with the mission to develop knowledge and technology that enables a transition to a sustainable energy system. Energy savings, the introduction of renewable energy and clean use for fossil fuels are the elements needed for the transition to a sustainable and affordable energy system.

ECN has more than 20 years of experience in the development, testing and operation of solar cells, modules and systems. The goal of ECN Solar Energy is to enable large-scale introduction of PV. This goal is pursued by developing technologies that improve performance, lower costs of PV technology, and provide for better system integration (for instance in the built environment).

 

About Teledyne Dalsa (TDA)

Teledyne DALSA has a broad experience in high-performance mixed-signal systems and circuits. Various innovate designs are implemented, silicon proven, published and patented. The chip design team in Enschede, The Netherlands, is driven by innovation and provides solutions to create high performance products with low power consumption. Teledyne DALSA works in close cooperation with the customer, starting with a system concept and followed by a design process. When the product performance is according specification it will be brought to production ramp up.

 

About the organization granting the subsidy

The TKI ZEGO (Top Consortium for Knowledge and Innovation for Solar Energy in the Built Environment) addresses the application of photovoltaic (PV) and thermal solar-energy for use in the in the built environment in the broadest sense (buildings and physical infrastructure).

TKI ZEGO supports projects that focus on the development of components and services that improve the performance of solar energy systems, the development of multi-functional solar construction material and solutions to integrate solar in smart grids and storage systems.
