PandaDoc or Ironclad for Commercial Solar EPC Contracts?

The EPC agreement is the core contract, and it's usually the one that gets negotiated hardest: performance guarantees on system output, milestone payment schedules, and change order terms if site conditions differ from what was scoped. In PandaDoc, this goes out as a detailed proposal that a client can redline through comments, workable for a firm doing a modest volume of projects. In Ironclad, the same agreement routes through structured approval before it's sent, which matters more once your performance guarantee language needs to stay consistent across many projects rather than getting rewritten deal by deal.

This agreement is largely dictated by the utility's own standard terms, so there's not much negotiating room regardless of which contract tool you use. What matters here is tracking the interconnection timeline and any conditions the utility attaches, since a missed condition can delay energization on a project where the client is already expecting power. This is closer to obligation tracking than contract negotiation.

Because the timeline depends on the utility's own processing speed as much as anything you control, keeping the client informed against real interconnection milestones, rather than an internal construction schedule alone, avoids a conversation later about why the system is built but not yet producing power.

If you're using subcontracted crews for installation, this agreement looks a lot like a construction subcontractor deal: insurance certificates, safety requirements, and a scope tied to the specific project. A fast e-signature workflow suits this well, since the same crews often work multiple projects and the agreement itself changes little project to project, beyond scope and schedule.

The one thing worth double-checking here is whether your subcontractor's insurance actually covers rooftop electrical work specifically, since a general contractor's liability policy doesn't always extend to that scope without an endorsement, and finding that gap after an incident is far worse than confirming it up front, especially on a rooftop job where the fall risk alone makes a coverage gap expensive to discover the hard way.

Unlike the EPC and subcontractor agreements, which close out once the project is done, the O&M contract runs for years and usually renews annually. It's the agreement most likely to matter long after the sales team has moved on to the next project, which makes it a strong candidate for obligation tracking: renewal dates, performance guarantee commitments tied to actual system output, and response time terms if something needs servicing.

Track these items on every O&M contract:

• The annual renewal date, since the contract usually renews each year and outlasts the sales team's attention.
• The performance guarantee commitments written into the contract.
• Actual system output from your monitoring platform, compared against what the contract promises, because neither contract tool measures performance itself.
• A named owner for the renewal calendar, whether it lives in a shared calendar for a small book or in an obligation tracking system for a larger one.

A firm doing a handful of projects a year with modest O&M volume can run all four documents through PandaDoc without much friction, tracking O&M renewals in a shared calendar. A firm with a growing O&M book, tracking performance guarantees and renewal dates across dozens of active systems while also negotiating EPC terms on new projects, benefits more from Ironclad's obligation tracking, particularly on the O&M side where the contracts pile up year over year in a way EPC agreements don't.

Some firms split the two deliberately: EPC agreements, negotiated less often and closed with a proposal tool's speed, stay on PandaDoc, while the O&M book moves to a system built for tracking recurring obligations once it reaches a certain size. That split isn't a compromise, it reflects that the two contract types genuinely behave differently, one closes and ends, the other renews and accumulates.

If you're evaluating tools with your whole contract portfolio in mind rather than picking one for everything, it's worth asking separately which tool your EPC pipeline needs and which your growing O&M book needs, since the honest answer for a mid-sized firm is often not the same tool for both, and forcing one tool to serve both jobs well is harder than it looks from the outside.
