Solar Contractor Software. Built by construction pros with honest pricing.

What Is Solar Contractor Software?

Solar contractor software is a project management platform built for companies that design, permit, install, and maintain photovoltaic systems. It connects site surveys, permit tracking, crew scheduling, material estimating, and utility interconnection paperwork in one system so solar jobs move from signed contract to final utility approval without delays.

Projul’s solar contractor software helps solar companies manage permit tracking, crew scheduling, and interconnection paperwork from one platform built by construction professionals who understand the documentation demands of solar installation. Projul offers flat-rate pricing with no per-user fees for construction companies of all sizes.

If you run a solar company, you already know the work is only partly about putting panels on roofs. The rest is paperwork. Permit packages for the AHJ. Structural and electrical engineering stamps. Utility interconnection applications. Net metering agreements. Incentive filings. Inspection scheduling. One missed document or expired deadline and your install crew sits idle while the office scrambles to fix it.

Solar software should eliminate that scramble. It should give every person on your team, from the sales rep running the site survey to the electrician wiring the disconnect, a clear view of where every job stands and what happens next.

Why Solar Companies Need Dedicated Software

Running a solar business on spreadsheets and email works until you’re juggling more than a few active installs. Then things start falling apart. Permit applications get submitted without the right attachments. Interconnection deadlines pass because nobody set a reminder. Your crew shows up to a job site where the permit hasn’t been approved yet.

Solar contractor software fixes these problems by turning your entire workflow into a connected system. When the site survey is complete, the estimating process begins in the same platform. When the estimate is approved, the permit tasks auto-populate. When the permit clears, the install crew gets scheduled. When the install passes inspection, the interconnection application moves forward.

That connected workflow is what separates solar contractors who grow from solar contractors who stay stuck at the same volume year after year. You can only make so many phone calls and send so many reminder emails before the system breaks.

Projul gives solar companies this connected workflow with 26+ features covering the full project lifecycle. Over 5,000 contractors across every trade rely on Projul daily, and solar contractors specifically benefit from the permit tracking, crew scheduling, and document management features that keep installs on track.

Manage Every Solar Job From Site Survey to Utility Approval

A solar install has more steps than most trades. Between the initial roof assessment and the final utility sign-off, you might touch a project 30 or 40 times. Each touch point is a chance for something to slip.

Projul puts every solar project on one dashboard where you see active bids, jobs in permitting, installs in progress, and projects waiting on utility approval. You spot the bottlenecks in five seconds. That project stuck in permitting for three weeks? You see it and make the call. Those two installs competing for the same crew next Tuesday? You catch the conflict before it costs you a day.

Site Surveys and Roof Assessments

Every solar job starts with a site visit. You need to assess roof condition, measure available space, check shading, note the electrical panel capacity, and determine if the structure can handle the load. If the roof needs repairs before you can install, that changes your timeline and your estimate.

Projul lets you log site survey findings directly on the project record. Attach photos of the roof surface, electrical panel, and any shading obstructions. Note structural concerns, roof age, and material type. When the project moves to estimating, all that information is already there. No second trip to the site because someone forgot to photograph the electrical panel.

Roof condition surprises are one of the biggest pain points in solar. You sell a job, pull the permit, schedule the crew, and then discover the decking is rotted and needs replacement before a single panel goes up. Detailed site survey documentation in your solar software helps catch these issues early, before they blow up your schedule and your budget.

System Design and Panel Layout Planning

Once the site survey is complete, you need to design the system. How many panels fit on the available roof area? What’s the optimal layout for maximum production? Which inverter configuration makes sense for this roof’s orientation and shading profile?

Projul’s document management lets you attach design documents, panel layout drawings, and engineering specs directly to the job. Your design team, your permit team, and your install crew all access the same files. When the AHJ reviewer asks a question about your panel layout, your office pulls up the answer in seconds instead of digging through a shared drive.

Permit Tracking That Prevents Costly Delays

Permit backlogs are the silent killer of solar company profitability. You have crews ready to install, but the AHJ is sitting on your permit application. Or worse, they rejected it because the structural calcs were missing a page.

Projul’s task management system lets you build permit checklists for every jurisdiction you work in. Structural engineering review. Electrical permit application. Fire setback compliance. Each item gets a due date and an assigned owner. When something stalls, you see it on the dashboard before it costs you a week.

Structural and Electrical Permit Packages

Most jurisdictions require separate structural and electrical permits for solar installations. The structural package covers roof loading calculations, attachment details, and racking specifications. The electrical package covers the PV system single-line diagram, conductor sizing, overcurrent protection, and rapid shutdown compliance.

Projul lets you track both packages as separate task sequences under the same project. Attach the engineering stamps, the plan sets, and the submittal receipts. Set reminders for expected review timelines. When one package clears and the other is still pending, you see exactly where you stand without calling the permit office.

Inspection Sequences

Solar installs typically require multiple inspections. Rough electrical, structural attachment, final electrical, and sometimes a separate fire safety inspection. Each one has to pass before you move to the next step, and each failed inspection pushes your timeline.

Build your inspection sequence as dependent tasks in Projul. The final electrical inspection doesn’t get scheduled until the rough electrical passes. When an inspector flags a correction, create a follow-up task, assign it to the right crew member, and track it through to re-inspection. Your interconnection application stays blocked until all inspections clear, and everyone on the team can see exactly what’s holding things up.

Utility Interconnection and Net Metering Paperwork

Interconnection delays are the other bottleneck that solar contractors can’t control but absolutely have to manage. You submit the application, and then you wait. Some utilities respond in two weeks. Others take two months. And if your paperwork is incomplete, you go to the back of the line.

Projul tracks every interconnection application as a task sequence tied to the project. Log the submission date, the utility contact, the application reference number, and the expected response window. Set a reminder to follow up if you haven’t heard back. Attach the net metering agreement, the utility approval letter, and the permission to operate when they arrive.

When NEM policies change mid-year, and they do, you update your task templates and every new project picks up the current requirements. Your office team stops scrambling to remember which rules apply to which utility territory.

Dealing With Interconnection Delays

Every solar contractor has jobs sitting in the interconnection queue right now. The install is done. The inspection passed. But the utility hasn’t issued permission to operate, and the system sits there generating nothing.

Solar software won’t make the utility move faster, but it will make sure you’re tracking every pending application and following up on time. Projul’s dashboard shows you every project in the interconnection stage, sorted by submission date. You see which ones are overdue for a response and which ones need documentation updates. That visibility turns interconnection management from a guessing game into a process.

Solar Estimating That Protects Your Margins

A solar estimate has a lot of moving parts. Panels, inverters, racking, wiring, disconnects, conduit, labor for the roof crew, labor for the electrician, permit fees, engineering costs, and sometimes roof repair. Miss a line item and you eat the cost.

Projul’s estimating tools let you build detailed solar estimates with every component as a separate line item. Save templates for your most common system sizes. A 7 kW residential rooftop with microinverters. A 12 kW system with a string inverter and optimizers. A 25 kW commercial ground mount. Each template includes all the materials, labor categories, and fees so you build accurate quotes in minutes instead of hours.

Inverter and Panel Inventory Tracking

Panel supply chain issues have burned solar contractors more than once in the past few years. You quote a specific panel, the customer signs, and then your distributor tells you it’s back-ordered for six weeks. Now you’re re-engineering the design for a different panel and re-submitting the permit package.

Projul’s material tracking on each project lets you log exactly which panels and inverters you quoted. When supply issues hit, you can quickly identify which active projects are affected and which ones need design changes. That beats discovering the problem when your crew shows up to install and the panels aren’t there.

Incentive and Rebate Tracking

The federal Investment Tax Credit, state rebate programs, and utility incentives all have their own application processes, deadlines, and documentation requirements. When these programs change, and they change constantly, your team needs to know immediately.

Projul lets you create incentive-related tasks on every solar project. Track the ITC paperwork that your customer’s accountant needs. Log state rebate applications with their submission dates and expected payment timelines. Set reminders for incentive program deadlines that could expire before your install is complete.

When a state program announces new requirements or reduced rebate amounts, update your templates once and every new estimate reflects the change. Your sales team stops quoting incentives that no longer exist, and your customers stop getting unpleasant surprises at tax time.

Schedule PV Crews Across Multiple Job Sites

Solar installation crews are specialized. Your racking crew, your panel crew, and your electricians each have different skills and availability. Scheduling them across multiple active jobs, each at different stages, is a puzzle that gets complicated fast.

Projul’s drag-and-drop scheduler shows every crew assignment across all your active projects. See at a glance who’s available Thursday, which job is waiting on a crew, and where you have scheduling conflicts. When a permit delay pushes one job back, reassign that crew to the next site that’s ready. No idle crews waiting on paperwork.

Solar contractors using Projul save 2+ hours daily on crew coordination and schedule changes. That’s time your project manager gets back to focus on keeping jobs moving instead of playing phone tag with installers.

Coordinating With Inspectors and Utilities

Solar scheduling isn’t just about your crews. You’re also coordinating with AHJ inspectors, utility meter technicians, and sometimes roofing subcontractors. Each of those parties has their own availability, and a missed appointment can push a project back a full week.

Projul lets you add inspector appointments and utility visits to your project timeline alongside your crew schedule. Everyone on the team sees the full picture. Your office knows when the inspector is coming. Your crew knows to have the site ready. Your project manager knows which jobs need attention today.

Maintenance Monitoring and Service Calls

Solar systems need ongoing attention. Inverter alerts, panel cleaning, critter guard repairs, and system performance checks all generate service calls that need tracking. If you installed the system, the customer is going to call you first when something goes wrong.

Projul lets you manage maintenance and service work in the same platform where you tracked the original install. Create a new project for the service call, link it to the original install record, and your technician has the full system history on their phone before they arrive. Panel model, inverter type, original install date, and any previous service notes are all right there.

Your Installers Run the Job From the Rooftop

Your PV crews are on rooftops all day and can’t climb down every time they need to check a spec. Projul’s native mobile app lets them view panel layouts, log time with geofencing, and upload progress photos without leaving the roof. When an inspector needs to see conduit routing or disconnect placement, your crew pulls it up on their phone right there on the ladder.

The app works on both iOS and Android and syncs to the office in real time. When your installer marks the racking as complete, your project manager sees it immediately and schedules the electrical rough-in. When the electrician finishes the wiring, the office triggers the inspection request. That kind of connected workflow keeps solar jobs moving without constant check-in calls.

Job Costing for Solar Projects

Solar projects have tight margins. Between equipment costs, labor, permit fees, and the occasional roof repair surprise, the difference between a profitable install and a money-losing one often comes down to a few hundred dollars.

Projul tracks estimated costs versus actual costs on every project in real time. You see where your labor dollars are going. You see which material line items are running over. If your electrician is taking twice as long on the wiring as you estimated, you know at day two, not at the end of the job.

Contractors using Projul report a 32% average profit increase. For solar companies, that increase comes from catching cost overruns early, estimating accurately, and billing for every change order instead of absorbing it.

Invoicing That Keeps Cash Flowing

Solar projects often involve milestone billing. A deposit when the contract is signed. A payment when the permit clears. Another when the install is complete. And a final payment after the utility grants permission to operate.

Projul lets you set up milestone invoices tied to project stages. When the permit clears, send the next invoice with one click. Your customer pays online directly from the invoice. The payment syncs to QuickBooks automatically. No more chasing checks or waiting 60 days because you forgot to send the bill.

Why Solar Contractors Switch to Projul

Most solar companies come to Projul after outgrowing spreadsheets or getting frustrated with solar-specific platforms that charge per user and still can’t handle basic project management. Here’s what makes Projul different for solar contractors:

• Built by a contractor. Kurt Clayson started Projul after years of running his own construction company. Every feature exists because a real contractor needed it.
• Flat-rate pricing. $4,788 per year for your entire company. No per-user fees. Your sales team, permit coordinators, crew leads, electricians, and office staff all get full access.
• All-in-one platform. CRM, estimating, scheduling, job costing, time tracking, invoicing, and document management. One login. One place.
• Rated 9.8 on G2. For both ease of use and quality of support. That rating comes from contractors who use it on actual job sites.
• Over 5,000 contractors. From residential solar installers to commercial PV companies running dozens of projects at once.

Interconnection Application Tracking From Submission to Approval

The interconnection application is where most solar contractors lose control of their project timelines. You submit the application, and then you wait. The utility reviews at their own pace. Some utilities process applications in two weeks. Others take two months. A few require multiple rounds of revisions before granting approval. And every day a completed system sits idle waiting for permission to operate is a day the customer is not generating credits on their electric bill.

The frustration is not just the wait. It is the lack of visibility into where things stand. Your office submits an interconnection application on Monday. Two weeks later, someone asks about the status. Nobody remembers exactly when it was submitted, which utility contact reviewed it, or whether the application reference number was logged anywhere. So someone calls the utility, sits on hold for 45 minutes, and finds out the application was rejected because a single-line diagram was missing a detail.

Projul tracks every interconnection application as a task sequence with dates, assigned owners, and attached documents. Log the submission date, the utility contact name, the application reference number, and the expected response window. Attach the submitted documents so you have a record of exactly what was sent. Set a follow-up reminder for two weeks after submission, or whatever the normal response time is for that utility.

When the utility responds, log the result on the task. If they request revisions, create a subtask for each required change, assign it to the right person, and track it through resubmission. If they approve, log the approval date and attach the permission to operate letter. The full timeline of the interconnection process lives on the project record, accessible to anyone on your team.

For companies working across multiple utility territories, this tracking becomes even more important. Each utility has its own application process, its own forms, its own review timelines, and its own quirks. Building task templates for each utility territory in Projul means your team follows the right process for the right utility every time. Your permit coordinator does not have to remember the differences. The template handles it.

The solar contractors who manage interconnection proactively are the ones who close out projects weeks faster than their competitors. Our solar installation guide covers the full project lifecycle, including interconnection best practices that complement this tracking approach.

NEM and Net Metering Documentation Per Utility Territory

Net energy metering policies affect your customer’s return on investment, which means they directly affect your ability to close sales. When a prospective customer asks how much they will save, the answer depends on which NEM tariff applies in their utility territory. NEM 2.0 customers in California get different credit rates than NEM 3.0 customers. Customers on time-of-use rates need systems designed to maximize production during peak price hours. Customers in territories with no NEM at all might need battery storage to capture any economic benefit from solar.

The documentation challenge is that NEM policies change. California moved from NEM 2.0 to NEM 3.0 and the economics shifted dramatically. Other states have modified or eliminated their NEM programs with little notice. If your sales team is quoting savings based on last year’s rates, you are setting your customers up for disappointment and yourself up for a complaint.

Projul lets you build NEM documentation into every solar project record. Attach the relevant tariff schedule, the customer’s current rate plan, and the projected credit rates used in your savings estimate. When NEM policies change, update your estimate templates to reflect the new rates. Every new proposal going forward carries accurate numbers.

For existing customers who signed contracts under one NEM tariff and got interconnected under a different one, having the original documentation on the project record protects you. You can show the customer exactly what rates were in effect when they signed, what was communicated in the proposal, and how the policy change affected their economics. That transparency does not eliminate the frustration, but it does prevent the dispute from turning into a legal problem.

Tracking NEM agreements per utility territory also helps your sales team have more informed conversations. When a lead calls from a specific zip code, your sales rep can pull up the NEM policy for that territory and give accurate savings estimates from the first conversation. That preparedness builds credibility and separates you from the solar companies that give vague answers and hope the customer does not ask follow-up questions.

For companies operating in states with rapidly changing net metering landscapes, maintaining a library of NEM documentation in Projul becomes a reference your entire team relies on. Your permit coordinator knows which tariff the customer is on. Your design team sizes the system appropriately for the applicable credit structure. Your accounting team invoices based on the correct incentive assumptions. One source of truth across every department eliminates the miscommunication that leads to unhappy customers and margin erosion.

Roof Assessment and Structural Load Verification

Every rooftop solar installation adds weight to the structure. A typical residential PV system adds 3 to 5 pounds per square foot to the roof. That does not sound like much until you consider that an older home with 2x4 rafters on 24-inch centers, original sheathing, and 20 years of weathering may not have the structural capacity to handle the additional load without reinforcement.

Discovering a structural deficiency after you have sold the job, pulled the permit, and scheduled the crew is expensive. At best, it means a change order for structural upgrades that the customer did not expect. At worst, it means canceling the project and refunding the deposit because the roof cannot support the system. Either outcome hurts your reputation and your bottom line.

Projul’s document management tools let you build roof assessment into the front end of every solar project. During the site survey, your team documents roof age, material type, condition, rafter size and spacing, sheathing type, and any visible damage or sagging. Attach photos of the attic structure showing rafter conditions and bearing points. If a structural engineer is required, attach their report and stamp to the project record before the permit package is submitted.

For re-roof situations where the existing roofing material needs replacement before panels go up, tracking the re-roof scope as part of the solar project keeps the full cost and timeline visible. Your customer sees the re-roof cost as a line item on the solar estimate, not as a surprise that surfaces after the contract is signed. Your crew schedules the roofing work ahead of the panel install so there are no delays waiting on a separate contractor.

Structural load verification also matters for commercial flat-roof installations where ballasted racking systems add significant weight. A ballasted system can add 5 to 8 pounds per square foot depending on wind zone requirements. If the building’s roof was designed to current code minimums, that additional load may require structural analysis and potentially roof reinforcement. Documenting the structural verification on the project record gives your engineering team, your permit team, and your install crew a shared reference point. Check our solar panel roof mounting guide for more details on attachment methods and load considerations.

The solar contractors who avoid roof-related project cancellations are the ones who invest time in the assessment phase. Front-loading that effort with thorough documentation in your solar software costs a few hours per project but saves thousands in avoided cancellations and change orders.

Inverter Monitoring and Warranty Tracking

Inverters are the most failure-prone component in a solar PV system. String inverters typically carry 10 to 15 year warranties. Microinverters often carry 25-year warranties. But warranty length does not matter if you cannot prove the unit failed under warranty conditions or if you do not have the serial number and installation date readily available when filing a claim.

When an inverter fails, the customer calls you. They do not call the manufacturer. They call the company that put panels on their roof. Your response time and your ability to resolve the issue quickly determines whether that customer recommends you to their neighbors or posts a one-star review online.

Projul stores inverter details on the original installation project record. Serial numbers, model numbers, installation dates, and warranty expiration dates are all accessible from your tech’s phone when they arrive at the service call. They confirm the unit is under warranty before they start troubleshooting. They document the failure with photos and notes on a new service project linked to the original install. When they contact the manufacturer for a warranty replacement, they have every piece of information the claims department asks for.

For microinverter systems with 20 to 40 individual units on a single roof, serial number tracking per unit is especially important. If one microinverter out of 30 fails, you need to know exactly which one, where it is on the roof, and whether it is still under warranty. Projul’s project records let you log each microinverter’s serial number and its position in the array layout. Your tech identifies the failed unit from the monitoring alert, looks up its position and warranty status in Projul, and arrives on site with the right replacement part.

Inverter warranty claims also require proof of proper installation. The manufacturer wants to see that the unit was installed according to their specifications, in a location with adequate ventilation, and on a circuit that meets their electrical requirements. Your original installation photos and project documentation in Projul provide this proof. Without it, the manufacturer may deny the claim and you are stuck choosing between eating the replacement cost or passing it to a customer who expected warranty coverage.

For companies that install battery storage systems alongside solar, the same tracking principles apply. Battery inverters, charge controllers, and the battery modules themselves all carry serial numbers and warranties that need long-term tracking. Building this tracking into your solar contractor software from the first install means you are never scrambling to reconstruct records when a component fails years later. Our free solar estimate templates include line items for these components to make sure nothing gets missed during the bidding phase.

Honest Pricing for Solar Contractors

Most solar-specific platforms charge per user, which punishes you for hiring. Add a permit coordinator? More money. Give your electricians access? More money. Let your sales team use the CRM? Way more money.

Projul starts at $4,788 per year for your entire solar company. No per-user fees. Your estimators, crew leads, permit staff, and office team all get full access without inflating the bill. Over 5,000 contractors use Projul to manage their operations, and solar contractors consistently report saving 2+ hours daily on admin work. G2 users rate Projul 9.8 for ease of use and 9.8 for quality of support.

Stop Losing Days to Permit Chasing and Paperwork

If your solar company is still tracking permits in spreadsheets, managing interconnection applications through email, and scheduling crews with group texts, you’re losing time on every single job. That lost time is lost money.

Solar contractor software like Projul brings your entire operation into one system. Site surveys, estimates, permits, schedules, installs, inspections, interconnection, and invoicing all connected. Your team spends less time on admin and more time putting panels on roofs.

Over 5,000 contractors have already made the switch. They’re catching permit issues earlier, keeping crews productive, and getting paid faster. Your competition is probably one of them.
