I Ticked Every Box on Solar Paperwork — and Still Got Rejected. Here’s My 5-Step Fix List.

I’m the guy who checks solar orders before they go to installation. For the last four years, I’ve been the final stop between a signed contract and a crew rolling up to someone’s roof. And in my first two years, I made enough mistakes to fund a small vacation. Actual tally: 17 rejected orders, roughly $12,400 in rework costs, and one very awkward call with a customer whose system was delayed because I misread the module wattage on her Sunrun lease buyout.

That call happened in September 2022. It was the third rejection that month. After it, I sat down with our lead installer and built the checklist I’m about to share. We’ve used it on every order since. In the last 18 months, we’ve caught 47 potential rejection triggers before they left my desk. Not bragging — that’s 47 errors I would have made without a system.

This list is for anyone who reviews solar contracts, processes P´s, or manages the paperwork-to-installation handoff. If you’ve ever submitted a file thinking “looks fine” only to get it bounced back, this is for you. Five steps. Do them in order.

Step 1: Confirm the Products Match the Contract Line-by-Line

You’d think this would be automatic. It’s not. Most rejections I’ve seen start here because someone copied a module model number from a quote without checking the latest spec sheet.

What to check:

• Panel make and model exactly as listed in the sales agreement
• Inverter type (microinverter vs. string vs. plug-in solar inverter if applicable)
• Battery system — if it’s a Brightbox, confirm the storage capacity and whether it’s AC- or DC-coupled

I once approved an order that listed a 400W panel on page one and a 390W panel on the equipment schedule. The contract said 400W. The warehouse picked 390W. The installer didn’t catch it until the panel was on the roof. Cost us $890 to swap plus a one-week delay. The lesson: match every line, not just the summary.

If you’re handling a sunrun solar bakersfield install, for instance, check that the local inventory actually carries the module specified. Sometimes a regional warehouse substitutes a tier-2 panel for the tier-1 listed in the contract. That’s a disconnect waiting to happen.

Step 2: Validate the Lease or PPA Terms Against the Order

This step catches the second most common error I’ve seen: misaligned financing. A lease renewal, a buyout option, or a PPA rate change can look correct to the eye but fail under audit.

What to verify:

• Is this a new lease, a lease transfer, or a Sunrun solar lease buyout? Each has different paperwork requirements.
• If it’s a buyout, does the order reflect the buyout price and a system ownership flag? I’ve seen orders submitted as leases when the customer already bought the system. That creates a tax credit mismatch.
• PPA rate per kWh — confirm it matches the signed contract, not the proposal draft

I’m not a legal expert, so I can’t speak to every state’s regulatory nuance. What I can tell you from an operations perspective is that a mismatch between the finance type and the order type is an automatic rejection trigger in most systems. Check it before submission, not after.

Step 3: Check the EV Charger Specs (If Included)

More solar contracts now bundle an EV charger. I’ve seen orders rejected because the charger model listed wasn’t compatible with the home’s electrical panel, or because the permit application didn’t include the correct charger specs.

What to look for:

• Charger model and amperage (e.g., 40A vs. 50A unit)
• Whether the charger requires a dedicated circuit
• Any compatibility notes — especially for older panels
• If the charger is an Ola EV charging station model, confirm the connector type (J1772 vs. NACS) and whether the home has the right outlet

This gets into electrical territory, which isn’t my expertise. I’d recommend consulting a licensed electrician if you’re unsure about panel capacity. But from a paperwork perspective, verify that the charger model listed in the order matches the one on the permit application. They don’t always align.

Step 4: Review the Electrical Plan for Clearance and Load

This step is easy to skip because the plan looks fine at a glance. But I’ve rejected orders internally because the electrical plan showed an inverter location that violated setback requirements, or the load calculation didn’t account for the Brightbox battery.

What to verify:

• Inverter location — is it within code distance of the main panel?
• Battery location — if adding a battery to an existing lease, does the plan show the new connection?
• Load calculation — does it include the new system’s AC and DC ratings?
• Any subpanel requirements

I once approved an order where the load calculation showed a 100A main breaker but the system required a 200A upgrade. The mistake wasn’t caught until the permit reviewer flagged it. That error cost $450 in revised plans and a three-day resubmission delay. The lesson: verify the load numbers yourself, even if you’re not the engineer. You’re checking for obvious mismatches.

Step 5: Confirm Site-Specific Requirements

This is the step most people forget because it’s not in the contract. It’s in the local building codes, the utility’s interconnection rules, or the HOA’s aesthetic guidelines.

What to confirm:

• Roof type and condition (composition shingle, tile, metal) — certain roofs require specific mounting hardware
• HOA approval (if required) — many rejections happen because the HOA documents weren’t submitted
• Utility net metering policy — confirm the customer’s utility allows the proposed system size
• Any local incentives that require specific equipment

For example, a sunrun solar bakersfield install might face different utility requirements than a similar system in Fresno. I can only speak to the markets I’ve worked in. If you’re dealing with a new jurisdiction, check the local utility’s website for interconnection guidelines before finalizing the order.

Common Mistakes I Still See (And How to Avoid Them)

Even with the checklist, I see recurring errors. Here are three that trip up most people:

1. Assuming all inverters are the same. People think a plug-in solar inverter is interchangeable with a microinverter system. They’re not. A plug-in inverter connects to a standard outlet and is typically used for small, DIY-style systems. Most residential solar arrays use microinverters or a string inverter. If the contract specifies one type, the order must list that exact type.

2. Forgetting to check the customer’s electrical panel. I’ve rejected orders because the panel was too old to accept a new double-pole breaker. The solution is to ask for a photo of the panel label before finalizing the order. It’s a five-minute check that saves a day of rework.

3. Skipping the surge protector review. This sounds trivial, but I’ve seen orders rejected because the electrician planned to plug a heater or other high-draw device into the same surge protector that powers the inverter. I’m not an electrician, so I can’t tell you definitively whether can I plug a heater into a surge protector is safe (short answer: generally not, because heaters draw high continuous current). What I can tell you is that if the plan shows a shared outlet, flag it. The inspector might.

The checklist isn’t perfect. Your mileage may vary depending on your local codes, your utility’s requirements, and the specific equipment you’re installing. But it’s saved us a lot of time and money. Hopefully it does the same for you.
