Our Story

Building the world's most trusted solar database, one project at a time.

The WikiSolar Story

More than a decade of solar market intelligence

WikiSolar began with a simple observation: despite solar power's explosive growth worldwide, there was no comprehensive, reliable source of data on utility-scale projects. Investors, researchers, and industry professionals were making decisions worth billions based on incomplete information.

In 2012, Philip Wolfe published the first major book dedicated to large-scale solar power generation—Solar Photovoltaic Projects in the Mainstream Power Market (Routledge). The research behind that book revealed both the massive scale of solar deployment and the critical lack of project-level data tracking it. WikiSolar was founded to fill that gap.

What started as a database supporting academic research has evolved into the industry's most comprehensive resource for utility-scale solar data. Today, WikiSolar tracks over 50,000 projects representing more than 1,000 GW of capacity worldwide—covering everything from 4 MW installations to multi-gigawatt solar parks across 180+ countries.

Our foundation rests on two pillars that competitors cannot replicate: a proprietary network of solar developers providing non-public project intelligence, and fifteen years of historical tracking that captures how projects evolve from announcement through commissioning and operation. This combination of breadth, depth, and accuracy has made WikiSolar the trusted source for investment banks, research institutions, energy consultancies, and policy organizations globally.

Under Philip de Koning's leadership, WikiSolar is modernizing its platform for the next generation of renewable energy data. The same commitment to data quality and comprehensive coverage that defined our first decade now drives our expansion into modern web delivery, enhanced analytics, and coverage of the complete renewable energy landscape.

Our Team

Philip Wolfe

Founder & Senior Advisor

Philip Wolfe has over 30 years of international experience in renewable energy. A first-class Cambridge engineering graduate, he led BP Solar as its first Chief Executive and later founded Intersolar Group, which became the UK's sole manufacturer of photovoltaic cells from 1993 to 2002. As Director-General of the Renewable Energy Association (2003-2009), Philip led the successful campaign for Feed-in Tariffs and the Renewable Heat Incentive in the UK. He founded Wiki-Solar to address the lack of comprehensive data on utility-scale solar projects worldwide. Philip authored the first book on utility-scale solar power (Routledge, 2012), has lectured at universities globally, and served on advisory boards to the European Commission and British Government. He was appointed Member of the Order of the British Empire (MBE) in 2016 for services to renewable energy.

Philip de Koning

Managing Director

Philip de Koning combines expertise in energy analytics, software engineering, and quantitative modeling to lead WikiSolar's technical evolution. At Aurora Energy Research, a leading global power market analytics firm, he led the development and launch of Aurora's flagship solar PV software for asset-specific valuation and yield modeling, managing teams across modeling, product development, and engineering. He also developed comprehensive fleet-wide models to represent solar production profiles with unprecedented accuracy—modeling the aggregate generation of individual solar farms at national and global scales. This work required comprehensive project-level solar data, and Philip found that WikiSolar was the only source meeting the standards necessary for professional energy market analysis. His deep familiarity with WikiSolar's unmatched data quality, combined with his background building modern data platforms, led him to join WikiSolar and drive its modernization. Philip holds an MSc in Econometrics from Erasmus School of Economics, where his thesis on power market forecasting at the Dutch Central Bank laid the foundation for his career in energy analytics. Prior experience in fintech and data science consultancy strengthened his expertise in large-scale data systems. He now focuses on modernizing WikiSolar's platform and expanding its capabilities, complementing Philip Wolfe's industry leadership and developer networks with technical innovation and analytical rigor.
