About Us

Solar Technology Systems Ltd is based in Sunny Nelson and has many distributors throughout New Zealand.

Solar Technology Systems is owned and operated by Frank and Roslyn Witowski.

Frank is the founder and driving force behind the business and has been working in a joint Venture with our Chinese Manufacturer for the past 6 years, to assure the highest possible quality control and the most efficient technology available on the market today.  

“I am a German Engineer and therefore have high expectations of our manufacturer to produce a top quality and highly efficient product.  I have very high standards in workmanship and the service I offer to my clients.”

As a result we are proud to launch our New Model Evacuated Tube Solar Collector onto the market.  Our New Model Sunsaver is compact and very smart to look at, with many improved features making it easier to install.  It is incredibly efficient, out performing all other Evacuated Tube Collectors on the New Zealand market. 

We enjoy working with our customers, and aim to provide them with excellent before and after sales service to ensure complete customer satisfaction.

Solar Electric Technology Systems Ltd is a sister company of Solar Technology Systems Ltd , with a focus on the electrical side of sustainable energy.

Solar Electric Technology Systems Ltd was formed in 2009 by Frank Witowski and Lance Double.

Managing director Lance Double is the driving force behind the business, with over 9 years experience in sustainable energy systems. "My prior experience and training as a Low Voltage Electrical Technician, has provided me with extensive knowledge of electrical systems such as used within sustainable generation."

Our aim is to provide complete sustainable energy solutions to our customers, with high standards of workmanship and customer service.

What our clients have to say

“From the initial stage of submitting a design and price, to the final commissioning of the system, Frank has been keenly involved and has stayed in close contact with us at all stages of the project. We have no hesitation in recommending Frank to prospective clients for his vision, enthusiasm and commitment.”

– Julian and Lesley Gray

“Solar water heating – where do you start? By good luck or fortune, I was introduced to Frank of Solar Technology. The benefit; a man who listens to you and works with you all the time. If you want careful attention to detail and, in my case, someone who believes in your project for solar underfloor heating and works tirelessly to make it happen, then I have to recommend Frank.”
