31 Aug Powercollectors demonstration project for Vineyard hotel
CAPE TOWN – August 30, 2016 – Solarus Sunpower´s South Africa branch on the 9th of August commenced with a 90 kWp hybrid installation at the Vineyard Hotel in Cape Town, providing 75kW peak thermal and 15kW peak electric output. As part of the drive towards holistic sustainability at their properties, the Petousis Group is committed to continuously improving levels of energy efficiency, especially where energy can be sourced from renewable sources. Their flagship property, the 207-room luxury Vineyard Hotel is therefore an excellent candidate for this demonstration project, subsidized by the Dutch government.
Vineyard hotel: “We hope other hotels will follow”
“Our target was to increase our conversion of solar energy and to produce thermal energy for heating water,” says Petousis CEO Lex Petousis. “Looking at all the options available, the space-saving solution offered by Solarus PowerCollectors 90kWp Hybrid system, which meets both requirements and is highly efficient on limited roof space, made these the obvious choice for the Vineyard Hotel. We are very proud that the Dutch government recognized our commitment to sustainable practices and chose to subsidize the installation of the Solarus PowerCollectors. We hope that the success of the project will encourage other hotels to follow suit.”
More projects are coming
With the installation at Vineyard, Solarus is making its official entry into the African market. More projects are in progress covering sectors like hospitality, housing, swimming pools, office real estate, farming and manufacturing.
About the installation
The installation consists of 60 PowerCollectors, which produce four times more total energy than traditional photo-voltaic installations of the same size, and provides heat to a thermal storage of 5 000 liters. This heat is then distributed to the 10 River Suite hotel rooms, the spa, gym and Splash Cafe.
Prior to installation, this water was heated using electricity, which to a large extent in South Africa, is generated by coal-fired power plants. This means that considerable carbon-emission saving achieved by utilizing the sun instead. The electricity produced by the PowerCollectors is connected with a grid tied connection to offset the energy demand even further. Advanced measurement tools will be installed to measure the total output of the system as well as the carbon savings. Readings will start as soon as the installation is completed by mid-October.

The hybrid (Photo Voltaic and Thermal – PVT) installation is the first of its kind in Africa. “It is great that pioneers like the Vineyard Hotel, a proud South African family-owned establishment, are showing leadership for a green future,” says Leen Zevenbergen, CEO of Solarus.
The installation partner for this project is Greenability, a leading service provider in the renewable-energy field in the Western Cape.
Quote from Joerg Schilling, CEO of Greenability
Joerg Schilling, CEO of Greenability says: We are always looking to improve our offering with products that give our clients the best solutions on the market. With the PowerCollectors we are able to meet two of the most important needs of our clients; heat and electricity in one system. In the past we installed separate Thermal and Photovoltaic Solar collectors; as the PowerCollector ticks both of these boxes, installation is quicker and more convenient. The system is also more effective than the independent units.”
Solarus is a private company founded in 2006 and it develops, produces and sells hybrid solar PowerCollectors. The company is headquartered in Venlo (The Netherlands) and has an R&D centre in Gävle (Sweden). Solarus works worldwide with local distributors and installers and is now active in Europe, (South) Africa, India, Brazil and Turkey. The company’s mission is “Solar power for the people”.
