The First 90 Days After You Acquire a Solar Asset

You just acquired a property with solar.

On paper, it looks like an immediate financial win—reduced utility costs, predictable savings, maybe even additional revenue streams.

In practice, what we often see is very different.

Across several recent client engagements, we’ve encountered the same issues within weeks of acquisition:

• Systems partially or fully offline
• Limited or missing documentation
• Little to no visibility into performance

None of this is unusual. But if left unaddressed, it can quietly erode the value of the asset you just acquired.

The first 90 days are critical. This is your window to establish control, restore performance, and ensure the system is actually delivering what you paid for.

Here’s where to focus.

1. Confirm the System Is Operating

Start with the basics, but don’t assume anything.

We routinely find systems that have been underperforming, or completely offline, without the new owner realizing it.

What to do immediately:

• Gain access to the monitoring platform (if available)
• Review recent production data
• Compare actual vs. expected output

No monitoring? You can still get a quick read in the field:

• Check inverter status screens (how many are online and producing?)
• For tracker systems, confirm they’re actively tracking—not stuck in stow or idle positions

Why it matters… You can’t monetize what isn’t producing.

2. Lock Down Interconnection & Tariff Details

This is one of the most overlooked and most important steps. Your utility agreement defines how the system creates value.

Track down:

• Interconnection Agreement
• Permission to Operate (PTO)
• Tariff enrollment details

These documents answer critical questions:

• What tariff is the system under (NEM, NEM Aggregation, RES-BCT, Net Billing)?
• Is it under NEM 1.0, NEM 2.0, or a newer structure?
• How long does that structure remain in place?

Why it matters… Two identical systems can have dramatically different financial outcomes depending on tariff structure.

3. Rebuild the Operating Playbook

In many acquisitions, documentation is incomplete or nonexistent. If available, gather:

• As-built drawings
• Equipment manuals
• Facility’s operation & maintenance manual

From there, establish a baseline operating plan.

At a minimum:

• Inverter maintenance schedules
• Tracker inspections and calibration
• Transformer and electrical checks
• Vegetation management and panel washing cadence

Why it matters… Without a defined plan, systems default to reactive maintenance, which will almost certainly result in significant savings losses.

4. Identify and Prioritize Issues

Nearly every acquired system is going to have problems. The key is understanding which ones matter most.

Common findings:

• Offline inverters or strings
• Monitoring/communications failures
• Tracker controller issues
• Utility-related disconnects or curtailment

Focus on building a prioritized punch list:

• What’s impacting production today?
• What creates risk for future downtime?
• What can be fixed quickly vs. planned?

Why it matters… Clarity drives speed and prevents wasted spend.

5. Re-baseline Financial Performance

This is where technical reality meets financial expectations. You need to answer: Is this system performing as expected?

Evaluate:

• Expected vs. actual production
• Historical & projected utility bill savings under current tariffs
• Additional value streams (e.g., monetizing Renewable Energy Certificates)

In many cases, underperformance isn’t one big issue, it’s multiple small ones.

Why it matters… This analysis informs every next step: repairs, upgrades, and long-term strategy.

The Bottom Line

Solar should be a high-performing financial asset, but it will only deliver if it is actively managed.

The first 90 days after acquisition are your opportunity to:

• Establish visibility
• Restore lost production
• Align the system with its intended financial performance

In our experience, this process almost always uncovers immediate upside—and sets the foundation for long-term returns.
