01 What we do
From alarms to long-term performance
Protect the asset.
Recover the output.
Commercial and agricultural solar systems need more than occasional attention. They need a team that can identify production loss, prioritize the work, repair equipment, verify the result, and carry the site history forward.
TerraSun builds service around the condition and operating demands of each asset, whether the need is a one-time corrective response or an ongoing O&M and asset-management program.

05 Common questions
Solar O&M
without the guesswork.
What belongs in a commercial solar O&M program?
A practical program can combine monitoring review, preventative maintenance, approved field inspection, corrective work, verification, and owner-ready reporting. The final scope should reflect the asset, operating environment, equipment, safety plan, and owner priorities.
What information should we provide for a performance review?
Send up to 12 months of production and interval data when available, recent alarms and inverter events, current drawings, equipment records, utility notices, and relevant maintenance history.
Does an alarm prove that equipment has failed?
No. An alarm can reflect equipment, meter, communications, shutdown, control, or grid conditions. The evidence and field findings determine the appropriate corrective path.
What is the difference between preventative and corrective maintenance?
Preventative maintenance is planned inspection and upkeep intended to identify or reduce future issues. Corrective maintenance is the approved diagnostic and repair response to an observed or suspected condition.
