Solargis to Power Renewable Energy Project Data Analytics for Apex in the US

Strong points :

  • In areas that do not benefit from high irradiance, using the right data to better plan solar installations makes a big difference.
  • Bifacial modules are now preferred in the United States due to their higher productivity, which makes data on the albedo effect even more important.

Solargis, a leading solar data services and software company, has provided its high-resolution granular resource and weather data to leading US independent power producer Apex Clean Energy (Apex). The data has been deployed to optimize more than 120 Apex solar projects during design, development and operation, while enabling projects to better integrate advanced technologies such as bifacial and storage.

The U.S. solar market is fast approaching a turning point as high oil prices make energy security a priority. Meanwhile, the industry navigates further uncertainty over hardware pricing and significant volatility in the global supply chain. Yet initiatives by developers and operators to better understand the abundant solar resource in the United States offer a way forward for the sector, maximizing the impact of new solar technologies to accelerate the shift away from dependence on fossil fuels.

According to the National Renewable Energy Laboratory (NREL), bifacial modules – which generate electricity from both sides of the panel – could already represent up to 50% of the installed capacity in the United States. However, there have been question marks over the industry’s ability to effectively utilize innovative module designs. To support Apex’s bifacial projects, Solargis has provided extensively validated albedo data, which measures surface reflectivity, unlocking optimal designs and more efficient operations.

Storage is another strong growth area for the solar sector, holding the key to wider deployment of photovoltaic technology. The desire to take full advantage of solar and storage projects has led to an increasing demand for accurate sub-hour time series data. Through their partnership, Solargis provided Apex Clean Energy with one- and five-minute accurate data to support seamless battery operations and better grid integration.

George Szabo, Director of Solar Design, Apex Clean Energy, said, “As the technological complexity of solar assets increases, high-quality resource data becomes more essential every day. Apex strives to create tangible value for every project, and Solargis – with the lowest GHI model uncertainty and inter-annual variability when paired with our ground-based monitoring stations – enabled our team to do just that.

Giridaran Srinivasan, CEO of Solargis for the Americas, said, “Increasing transparency around crucial project decisions means that US renewable energy investors are rigorously scrutinizing financial projections. We have always been impressed with Apex Clean Energy’s robust use of high-quality data and commitment to accuracy over the two years of collaboration, and we look forward to supporting the broader US solar industry as it takes a leap forward and takes a best practice approach to solar resource data.
