SolTec cc goes BIPV

Building-integrated photovoltaic (BIPV) are photovoltaic materials that are used to replace conventional building materials in parts of the building envelope such as the roof, skylights, or facades. They are increasingly being incorporated into the construction of new buildings as a principal or ancillary source of electrical power, although existing buildings may be retrofitted with similar technology. The advantage of integrated photovoltaic over more common non-integrated systems is that the initial cost can be offset by reducing the amount spent on building materials and labor that would normally be used to construct the part of the building that the BIPV modules replace. These advantages make BIPV one of the fastest growing segments of the photovoltaic industry.

CdTe Thinfilm Technology

CdTe is a near perfect material for PV application with a direct band gap of 1.5 eV that is closely matched to the terrestrial solar spectrum and a high optical absorption coefficient where less than 1 μm thickness is adequate to absorb the incident light. CdTe thin film solar cell and module technology has validated the economies of scale that were projected for thin film PV technologies since the early 1980s where manufacturing costs are now below $0.84 with module efficiencies of up to 16%. Additionally, the low-temperature coefficient of CdTe modules results in a high annualized output.

Quality modules from Germany

Established in 2005, Calyxo GmbH produces thin-film modules based on a Cadmiumtelluride-(CdTe-)Technology. Originally Calyxo had attained a worldwide exclusive license for a highly innovative glass coating technology from the US company Solar Fields. Calyxo initially set up a pilot line with a production capacity of 8 MWp in Bitterfeld-Wolfen/Thalheim (Germany) to show that the technology could be transferred to mass manufacturing and rapidly commercialized. The pilot line was set into operation in summer 2007. Due to raising demand a new 60MWp production line has been inaugurated in 2013.

SolTec – Your partner for BIPV and Calyxo

With a couple of projects completed now – starting in 2013 with the Spar Market in Swakopmund – we have found a PV technology that not only serves the common applications in Namibias under the intense high radiation well due to the heat efficiency of this module technology, we also can provide higher efficiency solutions for harsh whether conditions like those on the coast. With an integrated and nice looking aluminum substructure we aer ready to serve the “green building industry” to integrate PV into buildings from the start even possibly replacing old fashion construction material helping to cut down on initial investment.

The future of “Greenhouse Power”?

One of the recent SolTec projects to power a community greenhouse in Rehobot. We are committed to serve the agriculture businesses in Namibia with cost-efficient renewable power solutions. A future greenhouse project might integrate PV into the roof structure as is already demonstrated in various global greenhouse project. Renewable technology and food production is the perfect marriage of the future in order to produce more climate independent. Further development of solar pv & solar thermal applications contribute to such goal and SolTec cc in Namibia would be proud to become YOUR SOLUTION PARTNER.

Renewable energy conference in Parliament

WINDHOEK – The Parliamentary Standing Committee on Economics, Natural Resources and Public Administration is to host a two-day conference on renewable energy sources in Namibia, it announced yesterday.

The two-day conference would take place in Windhoek in the National Assembly chambers next week Monday and Tuesday. “It will be attended by more than 250 people including international and local experts on renewable energy sources, said the chairperson of the committee, Ben Amathila, at a press conference yesterday in the capital. According to him nine companies have also been invited to exhibit their products in the courtyard of the National Assembly.

Amathila said having visited local power generating projects in Namibia such as the Ruacana Hydro Power Station, Tsumkwe and also some in Germany the committee tabled a report in the National Assembly and its recommendations were adopted. He said one of the recommendations adopted was that the committee should organise an information-sharing session for all Members of Parliament on renewable energy sources and on how Namibia can become a renewable energy producer.

He further said one of the functions of the parliamentary standing committee is to promote economic development, natural resource management and public administration in the country. “The committee has an oversight function over ten ministries and associate institutions,” he added. According to him the aim of the conference is to share information, knowledge and experience on opportunities that renewable energy can offer in sourcing low-carbon electricity and to reduce dependency on fossil fuels and how Namibia can optimally utilize the resources. “The participation has been widened to include members of the public in accordance with Rule 44 (2e) of the Rules and Orders of the National Assembly,” he further explained. Among the topics to be discussed is the current status of the energy sector in Namibia, energy options available in Namibia, the Independent Power Producer (IPP) framework and its current status, as well as success stories and challenges experienced in the energy sector. Current local power generation capacity is limited in Namibia and additional electricity is imported from South Africa, Zimbabwe, Mozambique and Zambia.
