• Holistic Solar was founded by Zoltan Kiss, a physicist who has worked for the last 40 years in photovoltaics in the US. His company Chronar also built the first SPV factory in Harbin, China, in 1988. He founded Holistic Solar in 2016, to commercialize the most generic product of the Age of Solar 2, the REBOX.
  • “Here comes the Sun.” The charter of Holistic Solar is to contribute to the clean energy revolution to the 21st century as the fossil fuel based energy industry is changing to solar based, clean energy.


Holistic Solar family of companies is coordinated by Holistic Solar Holding Corp. The holding company is registered in the US. It is the owner of all intellectual property of the family of companies. HSH also holds shares in the operating companies in proportion to the operating company’s use of the proprietary technology.

There are two OEM manufacturers, HS-SVDS in Germany develops and manufactures the equipment to produce the Holistic Solar proprietary multi-junction thin film SPV modules.

The second OEM company HS-Hu, located in Hungary, produces the HS proprietary electrolyzer and NIFEL storage device. The NIFEL contains  batteries, electrolyzer and hydrogen storage.

The most important activity in the Holistic Solar family is the production of our main line of our products, the REBOX. In the diagram four such companies are identified. These are the Super Factories that manufacture the REBOX. For the moment, there are four such companies, the US, in Hungary, in Germany and in China (in the process of incorporation). The Super Factories are also called SSPV, Self-Sustaining PV industry. These are modern day “Sun-Wells”, replacement for the oil-wells of the last century.

Associated with each SSPV in the different countries, there is a franchise of MEPIS (Manufacturing, Engineering, Procurement, Installation and Service).

Our history

Some personnel of Holistic Solar were present at the birth of the modern PV industry in the early 1960’s. Bell Labs and RCA Labs were the first ones to make crystalline solar panels. At the same time, amorphous Silicon thin film was also demonstrated as a PV device. Some of the highlights of this journey:


First Solar calculator –Princeton, NJ by Optel 1971

First SPV watch by Optel 1973

First thin film module manufacturing of Port Jarvis, NY by Chronar 1982

First PV power project Birmingham, Alabama by Chronar 1985

First SPV consumer product the Walklite by Chronar 1986

Sale of first PV factory Lens, France by Chronar 1986

First PV factory in Harbin, China by Chronar 1988

BIPV Times Square, New York City by EPV 2002

SPV water pumping in Africa by Nanergy 2006

Tandem aSi devices and manufacturing by Amelio 2008

PV DUO demonstration by Amelio in Munich 2010

Our Present

The PV industry is going from the age of Solar 1 to the age of Solar 2. Major changes are taking place throughout the industry.

The most important goal is to reduce further the cost of SPV generated electricity from the present $0.10 per kWh by an additional factor of 3 to below $0.03 per kWh (in areas of insolation of 2000 hours). This cost reduction is feasible based on past research. Holistic Solar is involved in materials and device research to increase the efficiency of multi-junction thin film modules to 30%.

The energy storage associated with renewable SPV generation is a most important issue. Holistic Solar is exploiting the NiFe battery technology to provide storage for 10,000 cycles, to last as long as the SPV modules last.

Third party leasing arrangements double the cost of SPV electricity for the user. Holistic Solar offers the user/owner a line of REBOX products as the best economical and social solution for Main Street.

In the age of Solar 2, Holistic Solar wants to participate in job creation and other socio-economic benefits of the SPV industry.

Life, liberty and compassionate pursuit of happiness 

Our Future 

Holistic Solar, recognizing its responsibility to its neighbors and the community, is planning to build in the coming age of Solar 2, a franchise of self-sustaining communities. These communities will be the key pillars of a distributed energy supply through the use of REBOX and associated microgrids. To maximize job creation and local independence, component manufacturing of SPV modules, batteries and product assembly will be integrated into these self-sustaining communities (SSPV). The SSPV will also establish service/maintenance centers and will be able to take care of a trouble free SPV electricity generation.

We believe that the SPV industry will be a long term source of job creation, as in the 21st century the fossil fuels as an energy source will be gradually replaced by SPV energy generation. We hope and work so that the SSPV franchise can become the model of a new spirit in our lives based on a modified motto of “life, liberty and compassionate pursuit of happiness’.
