O&M

Person Cleaning Solar Panel

February is Operations and maintenance (O&M) month on SolarBuildermag.com. O&M is arguably the most crucial component to the long-term success of the solar industry. Here, solar pros — from residential installers to large-scale fleet managers and asset owners — will find solar O&M news and insights to bolster the long-term performance of every solar PV plant in their care.

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

Protecting (and insuring) against PV portfolio underperformance

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

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

How array-powered DC-DC converters reduce capital costs for PV monitoring

February 18, 2020 at 10:00 am 0 comments

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
