OKE-Services is the one-man company of Henk Oldenkamp. OKE-Services wants to contribute to an increase of renewable energy applications: solar photovoltaic energy, wind energy, geothermal energy, et cetera. In our view, this is the only way to decrease the use of fossil fuels and the output of CO2 emissions, and not pollute the world even more. And of course nuclear energy is not an option since there is no long term solution for the nuclear waste.

Since Henk Oldenkamp is an electro technical engineer, his main activity is designing and developing highly efficient and innovative electronics. In view of the goals of OKE-Services, these are primarily intended to stimulate the use of photovoltaic systems. However, OKE-Services also designs converters and power supplies for consumer electronics and electronics for LED applications aiming at a more efficient use of energy.

Designing and developing new products can be either on Henk’s own initiative, or in cooperation with an interesting party, or by order of a third party. Currently the following products are being developed:

  • PV-wirefree is a new approach in designing PV-systems consiting of only four main components, which reduces the price considerably and increases the output of a PV-system.
  • PV-watchdog is an extremely small and low-cost monitoring device, which is integrated into a PV laminate, which detects and signals whether a PV module is working properly.
  • Active diode of OKE-Services (ADO) is a smart electronic diode which also can be used for PV-modules. Since it is very small and extremley thin, it can be integrated into a PV-module.
  • OK4all is the long expected follow-up of the OK4, an AC module inverter of ca. 200 Watts. We intend to make the design 'an open source', which will be published on the internet, so that anybody will be able to produce it.

Besides designing and developing of electronics, OKE-Services also advises about renewable energy, and sells photovoltaic modules and small wind turbines. We mainly focus on autonomous systems with an annual output of not more than 1000 kWh. These activities are being executed together with Irene de Jong in the renewable energy shop EVA, Energie Voor Altijd (Energy For Ever) at Keizerstraat 121 in Scheveningen (The Hague).
