An urban integration demo by PETROBRAS

This project funded by the brazilian utility Petrobras was to install three HCPV systems in a parking lot area for urban integration. The systems were installed in the SESI (Serviço Social da Indústria) facilities.

This project has been funded by the Brazilian oil company Petrobras. It required the installation of three HCPV systems in a parking lot area in the city of Natal within the the facilities of SESI (Serviço Social da Indústria).

TRACTEBEL’s technology survey for Brazil

This project was funded by the Brazilian utility Tractebel Energia. Its target was to test a set of 7 different technology and engineering options for the production of photovoltaic electricity, in a set of 8 different locations in Brazil chosen to sample the different climates and environmental conditions in the country’s territory.

HCPV was one of the chosen technology options, and BSQ supplied all 8 x 13.44kW systems. Another of the system options that is tested, is that of two axis tracking PV, and also here the trackers are supplied by BSQ.

BSQ CPV Sun Tracking Control Unit

BSQ Sun Tracking Controller (STCU) uses ephemeris based open loop tracking plus a proprietary autocalibration model the BSQ Sun Tracking Control Unit achieves 0.1 degree pointing accuracy

  • 2σ (percentile 97) accuracy of 0.1°
  • Universal controller for one or two axis trackers with any tracking axes architecture
  • Large track record proves reliability under harshest weather conditions

Laboratory Sun Tracker HASTLA

These laboratory trackers are something unique in the market as they combine very high subdegree sun tracking accuracies, with a sturdy tracking structure with aperture surfaces of as much as 10m2, especially designed for holding different models of CPV or PV modules of different sizes and manufacturers:

  • Custom designs to meet the needs of research groups
  • Integrates BSQ’s high tracking accuracy technology
  • Can be supplied with non invasive foundation kit and adaptable supporting metal frame

The NGCPV power plant

The Villa de Don Fadrique plant, is a 70kW HCPV plant built within the framework of the NGCPV Euro-Japanese project. It consists of five 13,44kW systems, each hosting 48 modules with a concentration ratio of 820X. It is grid connected through a 60kW inverter by Fronius, and a 100kVA transformer that raises the output voltage up to 20kV

This power plan was installed within the bounds and using the facilities of a bigger PV plant of 700kW based on conventional flat plate modules, with a fixed tilted mount. Located in the town of Villa de Don Fadrique in Castilla-La Mancha (Spain), the whole plant is operated by Spanish PV developer Generaciones Fotovoltaicas de La Mancha. It is grid connected, selling its production to the Spanish wholesale electricity market.

CPV Designs for urban integration

BSQ Solar can provide custom made HCPV system designs specially devised for installation in urban areas. The trackers here include larger poles, large enough to allow transit of people and vehicles underneath the HCPV array.

Can be integrated in parking areas, public or even domestic gardens, they are ideal to tap HCPV’s superior surface energy density – up to three times bigger than that of conventional photovoltaics – in cities with scarce and expensive land.

Low profile CPV system designs

We design and produce customized HCPV systems with reduced heigth and/or enhanced landscape type aspect ratios. These are optimal for installations and power plants were visual impact has to be reduced due to environmental reasons.

    Tipical characteristics:

    • Peak power output: 5 – 7 kW
    • Maximum heigth: < 5m
    • Landscape aspect ratios
    • Simple assembly and maintenance without needing manlifts

820X CPV Module BSQ-D280

With the largest operating track record in the market, the BSQ HCPV module combines high efficiency and high concentration non-imaging optics with a simple and rugged design:

  • 280W STC peak power output
  • Concentration factor of 820X
  • Dome shape-fresnel lens that maximizes the pointing tolerance up to 1º
