Vegetation Management in O&M base scope

  • Typically includes: one annual spray of pre-emergent under panels and around sensitive equipment, and 2-4 mows per year to keep vegetation at a safe height.
  • Lower cost per application/mow
  • Staff dedicated to site or small region and able to support PM activities in the non-cutting season

Vegetation Management can cost more than the O&M – let us help you keep costs down!

Pre-COD Services

Ensuring System Integrity, Safety and Performance


Commissioning is the final verification process used to compare and confirm an installed project to its designed plans and engineering. NovaSource’s team has commissioned over 1GW of PV installations. We help our clients lower the economic risk of their projects by identifying quality of workmanship, materials used and ensure system integrity for the lifespan of the system.

Our experience in risk evaluation, factory inspections and failure analysis of the key components (PV Modules, Inverters, Switchgears, Transformers) and high-quality customer communication, help to bridge the gap between EPC and O&M group, whether that is NovaSource or an alternative provider.

Hail Stow Services

Single stow tracker command functionality is critical. 

Hail damage is a serious risk to solar plants in many parts of the US. NovaSource pre-emptively stows plant trackers to reduce risk of hail damage. 

This critical service is executed by the world class NovaSource Operations Center with 24/7 manned operations. 

Pre-emptive stow dramatically reduces the risk of hail damage by moving the vulnerable module surface to a high stow angle. 

NovaSource monitors severe weather threats using a third-party forecasting partner and pre-emptively stows plant trackers in a favorable orientation to reduce risk of hail damage

Forecasting Service Capabilities

  • NSPS partners with a tier 1 commercial forecasting service​
  • Partner provides severe weather alerts (lightning, tornadoes, hail, etc) to companies, government institutions​
  • Severe weather alerts are issued by meteorologists from 24/7 forecasting center​
  • Positive communication maintained with follow-up phone call if NSCR does not acknowledge alert
