Improving solar plant generation predictions with machine-learning techniques
Accurately predicting power generation for PV sites is critical for prioritizing relevant operations & maintenance activities, thereby extending the lifetime of a system and improving profit margins. A number of factors influence power generation at PV sites, including local weather, shading and soiling losses, design of modules, DC mismatches, andRead More — Solar Builder magazine

Protecting (and insuring) against PV portfolio underperformance
Underperformance is becoming a not-so-secret issue for large-scale solar portfolios (we have heard anywhere from 3 to 6 percent in some portfolios). The reasons for this often say less about the viability of solar technology and project revenue potential and more about process and prediction of failures somewhere along theRead More — Solar Builder magazine

South Dakota co-op Basin Electric buys large-scale solar generation for the first time via this PPA
Geronimo Energy, a National Grid company, and Basin Electric Power Cooperative announced a Power Purchase Agreement (PPA) for the Wild Springs Solar Project. Wild Springs is a 128 megawatt (MW) clean solar energy project located in Pennington County, South Dakota, approximately 20 miles east of Rapid City. Wild Springs isRead More — Solar Builder magazine

Details on first ‘solar pasture’ seed mix to benefit solar site vegetation and sheep nutrition
The interest in more sustainable solar sites continues to (yes, I’m doing it) grow. Pollinators are being added, vegetation is improving, and sheep are being deployed to eat that vegetation. Now it’s time to this all together and make sure those sheep are eating right too. Ernst Conservation Seeds, theRead More — Solar Builder magazine

How array-powered DC-DC converters reduce capital costs for PV monitoring
Solar arrays, particularly utility-scale and commercial and industrial (C&I) installations, collect a significant amount of data for efficient asset management and qualitative operational metrics such as performance ratio. A substantial amount of this data can be collected from inverters and substations with easy access to AC power and communications. However,Read More — Solar Builder magazine
