Best ERP Software for Solar Installers in 2026

The best solar ERP is not always the biggest software

Most solar companies do not start with an ERP problem.

They start with a spreadsheet.

Then a CRM.

Then a design tool.

Then a project management board.

Then WhatsApp groups, email threads, Google Drive folders, accounting software, permit trackers, crew schedules, and a few “temporary” spreadsheets that somehow become permanent.

At 5 or 10 projects a month, this can still work.

At 20, 30, or 50 active projects, the cracks become obvious.

Sales has one version of the project.
Permitting has another.
The field team is waiting on the latest plan set.
Finance does not know when to invoice.
The owner has to ask three people for one simple answer: “Where is this job stuck?”

That is where solar ERP becomes important.

The best ERP software for solar installers in 2026 is not just the system with the most features. It is the system that helps your team control the full solar workflow from lead to PTO to cash.

Quick answer: what is the best ERP software for solar installers in 2026?

The best ERP software for a solar installer is the one that connects your customer, project, permit, interconnection, field, inventory, finance, and reporting workflows in one place.

For larger solar companies already committed to NetSuite, SolarSuccess by Blu Banyan is one of the most established solar-specific ERP options. Blu Banyan positions SolarSuccess as a NetSuite application for residential, commercial, and utility-scale solar businesses.

For teams looking for a field and operations hub, Scoop Solar and Sitetracker are also relevant options. Scoop positions itself as a central operations hub for solar and renewable installation teams, while Sitetracker focuses on renewable energy asset lifecycle management.
For sales and design-heavy workflows, tools like Aurora Solar, OpenSolar, and SurgePV are strong, but they are not the same thing as a full solar ERP. Aurora describes itself as a platform to sell, design, finance, and deliver solar and storage; OpenSolar focuses on free software to design, sell, and manage projects; SurgePV focuses heavily on AI roof modeling, shading analysis, financial modeling, and branded proposals.
For growing installers who want one solar-specific operating system without stitching together too many tools, Solar1 is being built around the operational gap most teams feel after the sale: permitting, interconnection, field work, finance visibility, and project control from lead to PTO.

Why solar ERP matters more in 2026

The solar market is not short of demand. The harder problem is execution.

SEIA’s Q2 2026 Solar Market Insight notes that U.S. solar growth is facing headwinds including permitting bottlenecks, interconnection timelines, and equipment timelines.

The U.S. Department of Energy also defines solar soft costs as including design, siting, permitting, installation, interconnection, financing, customer acquisition, workforce training, supply chain, inventory control, and operating overhead.

That matters because most of these are not panel problems.

They are workflow problems.

A delayed permit is a workflow problem.
A missing field update is a workflow problem.
A PTO follow-up that nobody owns is a workflow problem.
An invoice that does not go out after a milestone is a workflow problem.
A crew arriving before the site is ready is a workflow problem.

Solar ERP is valuable because it brings those moving parts into one system instead of leaving them scattered across disconnected tools.

What should solar ERP actually manage?

A real solar ERP should help manage more than tasks.

At minimum, it should cover these workflows:

Workflow

What needs to be tracked

Why it matters

CRM and sales

Leads, proposals, deal stage, customer data

Prevents handoff gaps after a sale closes

Site survey and design

Survey notes, plan sets, design status, revision history

Keeps design and field teams aligned

Permitting

AHJ requirements, submission status, comments, resubmissions

Reduces permit confusion and delay

Interconnection

Utility applications, approvals, PTO status, follow-ups

Prevents cash from getting stuck after install

Field operations

Crew schedule, job readiness, mobile updates, photos

Reduces office-field misalignment

Inventory and BOM

Panels, inverters, racking, job materials, shortages

Protects schedule and margin

Finance

Milestones, invoices, payments, job costing

Connects project progress to cash flow

Reporting

Stuck projects, team workload, margin, cycle time

Gives owners visibility without chasing people

If a system only manages leads, it is not ERP.

If it only creates proposals, it is not ERP.

If it only tracks tasks, it is not ERP.

A solar ERP should help the company answer:

What is sold, what is stuck, what is ready, what is installed, what is waiting for PTO, what can be invoiced, and where are we losing margin?

Solar ERP vs CRM vs project management software

A lot of solar companies confuse ERP with CRM or project management software.

That is normal, because many tools overlap.

But the difference is important.

A CRM can help you win the customer.

A design tool can help you sell the system.

A project board can help you track tasks.

But solar ERP should help you run the business after the customer says yes.

That is the difference.

The best ERP options for solar installers in 2026

There is no single “best” answer for every installer.

A 10-person residential installer does not need the same system as a multi-state EPC. A commercial solar contractor does not have the same workflow as a residential team doing high-volume installs.

Here is the practical way to look at the market.

1. Solar1 ERP - best for installers who want operational control from lead to PTO

Best fit: Growing solar installers and EPC teams that want one connected workflow for sales, permitting, interconnection, field work, inventory, finance, and reporting.

Solar1 is being built for the part of solar operations that gets messy once the business starts growing.

The key problem Solar1 is focused on is not just “project management.” It is the gap between departments.

Sales closes the deal.
Design prepares the system.
Permitting handles AHJ requirements.
Operations schedules the crew.
Field teams complete the install.
Interconnection waits for utility approval.
Finance waits for the right milestone.

If these steps live in different tools, the business starts leaking time and margin.

Solar1’s angle is simple:

Solar companies need one operating system from lead to PTO, not another disconnected tool.

What Solar1 should be strong at:

• Solar-specific CRM and project workflow
• Permit tracking
• AHJ requirement tracking
• Interconnection and PTO tracking
• Field updates and mobile access
• Inventory and job material visibility
• Finance milestone visibility
• Owner dashboards
• One source of truth across teams

Best for:

• Installers outgrowing spreadsheets
• Teams managing 20+ active projects
• Operations-heavy solar businesses
• Solar companies that need better visibility before hiring more admin staff

Watch out for:

If a company only needs basic design and proposal software, Solar1 may be more than they need. Solar1 makes more sense when the real pain is operations, not just proposal speed.

2. SolarSuccess by Blu Banyan - best for NetSuite-based solar ERP

Best fit: Larger solar companies that want a NetSuite-based ERP and have the budget and implementation capacity for a heavier business system.

SolarSuccess is one of the most recognized solar ERP options because it is built around NetSuite. Blu Banyan describes its solar solution as a way to unify solar business operations on one cohesive platform and create a single source of data.

This can be powerful for solar companies that need deep accounting, inventory, procurement, project management, and enterprise reporting.

Good fit when:

• You already use or want NetSuite
• You have complex accounting and inventory needs
• You have a larger team and formal implementation budget
• You need enterprise-level reporting

May not fit when:

• You want a lighter, faster setup
• Your team is not ready for a heavy ERP implementation
• You need something more installer-friendly and operationally simple
• You are still validating your internal process

SolarSuccess is serious ERP. That is its strength. But for some growing installers, the question is whether they need a full NetSuite-based system now or a more focused solar operations platform first.

3. Scoop Solar - best for field and operations coordination

Best fit: Solar and renewable installation teams that want a central operations hub connecting field work, project workflows, and existing systems.

Scoop positions itself as a central operations hub for solar and new infrastructure teams, focused on connecting existing systems into a single operational backbone and reducing duplicate work.

This makes Scoop relevant for companies that are struggling with field execution, handoffs, and operational visibility.

Good fit when:

• Field teams and office teams are misaligned
• You want mobile work apps
• You want to connect existing tools rather than replace everything
• Your biggest problem is workflow execution

May not fit when:

• You want a complete ERP with finance, inventory, and solar-specific commercial workflows in one place
• You want to rebuild your full company operating system
• You need deeper accounting and ERP controls

Scoop is worth studying because it clearly understands the operations pain. For Solar1, the opportunity is to go even deeper into the full solar business workflow: permit, PTO, field, inventory, finance, and owner-level visibility.

4. Sitetracker - best for renewable asset lifecycle management

Best fit: Larger renewable energy teams managing complex infrastructure projects and asset lifecycle workflows.

Sitetracker describes its solution as purpose-built renewable energy project management software for solar, storage, and wind projects, including standardizing digital processes from financial management and regulatory compliance to installation.

This makes it more relevant for larger deployment teams, infrastructure companies, and organizations that need asset lifecycle management.

Good fit when:

• You manage high-volume or complex renewable deployments
• You need asset lifecycle management
• You have regulatory and compliance-heavy workflows
• You are operating at enterprise scale

May not fit when:

• You are a smaller installer looking for a simpler solar ERP
• You want a more installer-native system
• You need a practical lead-to-PTO workflow without enterprise complexity

Sitetracker is strong for infrastructure operations. Solar1 can differentiate by being more directly focused on solar installers and their daily project workflow.

5. Aurora Solar - best for design, sales, and solar project modeling

Best fit: Solar companies that need strong design, sales, modeling, and proposal workflows.

Aurora positions itself as a platform to sell, design, finance, and deliver solar and storage. It is widely known in the solar market, especially for design and sales workflows.

Aurora can be a strong part of the software stack, but it should not automatically be treated as the company ERP.

Good fit when:

• You need accurate solar designs
• You need strong proposal workflows
• Your sales/design team needs speed and consistency
• You want a recognized solar platform

May not fit when:

• Your main problem is post-sale operations
• You need deeper permit, field, finance, inventory, and PTO control
• You need one ERP layer across the whole company

Aurora can help you sell and design solar. But if your bottleneck is what happens after the deal closes, you may still need a solar ERP or operations system.

6. OpenSolar - best for free design and sales workflow

Best fit: Smaller or cost-sensitive solar teams that want free software for design, sales, and project management basics.

OpenSolar describes its platform as free software for solar professionals to design, sell, and manage projects. OpenSolar also explains that its software remains free because partners pay to be part of the platform.

That is a strong offer.

For early-stage installers, free software can be a huge advantage.

Good fit when:

• You are cost-sensitive
• You need design and sales tools
• You are still early in your software journey
• You do not yet need deep ERP controls

May not fit when:

• You have complex operations
• You need deeper finance and inventory visibility
• You need advanced permit/PTO workflows
• You are scaling beyond simple project tracking

OpenSolar is not the enemy of solar ERP. It may sit earlier in the software journey. As teams grow, the question becomes whether free sales/design software is enough to run the full company.

7. SurgePV - best for AI design, roof modeling, and proposal workflows

Best fit: Installers and EPCs that want fast AI roof modeling, shading analysis, financial modeling, and proposal generation.

SurgePV positions itself as solar design and proposal software with AI roof modeling, shading analysis, financial modeling, and branded proposals.

This makes it especially relevant for design and proposal speed.

Good fit when:

• You want faster roof modeling
• You need strong proposal visuals
• Your design team is overloaded
• You want a cloud-based design/proposal workflow

May not fit when:

• You need full ERP depth
• You want finance, inventory, PTO, field operations, and project controls in one system
• Your biggest pain is operational handoff after the sale

SurgePV can be valuable in the design/proposal layer. Solar1’s opportunity is the operating layer that sits across the rest of the project lifecycle.

How to choose the right solar ERP

Before choosing software, do not start with feature lists.

Start with the workflow that is breaking.

Ask these questions:

1. Where do projects get stuck most often?
2. Who has to chase updates every day?
3. Which team has the least visibility?
4. What information gets entered twice?
5. When does finance know a project is ready to invoice?
6. How do you track permit status by AHJ?
7. How do you track interconnection and PTO?
8. Can the owner see all active projects without asking the team?
9. Can the field team update the job from mobile?
10. Can you see margin by project before it is too late?

If a tool cannot answer these questions, it may not be your ERP. It may only be one part of your stack.

The ROI case: where solar ERP pays back

Solar ERP ROI usually comes from four places:

1. Less admin time
2. Fewer project delays
3. Faster billing and cash collection
4. Better margin visibility

Here is a simple example.

Assume your team has 5 people who each spend 30 minutes per day chasing updates, checking spreadsheets, asking for job status, or confirming what happened in the field.

5 people × 30 minutes/day × 5 days = 12.5 hours per week

That is 50 hours per month.

If the loaded cost of that admin/operations time is $40 per hour, that is:

50 hours × $40 = $2,000 per month

That is only the visible time loss.

It does not include:

• delayed invoices
• rework
• missed material issues
• customer frustration
• extra meetings
• crew downtime
• owner time spent chasing updates

Now look at permitting.

NREL’s SolarAPP+ performance review found that a typical SolarAPP+ project was permitted and inspected 14.5 business days sooner than traditional projects in 2023.

That does not mean every solar ERP will automatically save 14.5 days. But it proves something important:

Process speed matters. Permitting speed matters. Workflow visibility matters.

If a solar installer has 10 projects delayed because nobody is tracking permit comments, interconnection status, or PTO follow-up properly, that delay can quickly turn into cash-flow pressure.

A simple cash-flow example:

$25,000 average project value × 10 delayed projects = $250,000 sitting in delayed project flow

Again, this is not a Solar1 guarantee. It is the kind of operational math every installer should be doing before buying software.

What features should the best solar ERP have?

Use this checklist before choosing any solar ERP.

1. Solar-specific project lifecycle

The system should understand the real solar flow:

Lead → proposal → site survey → design → permit → install → inspection → interconnection → PTO → invoice → closeout.

If you have to force your workflow into a generic project template, the system may create more work than it removes.

2. Permit tracking

You should be able to see:

• permit status
• AHJ
• submission date
• expected review window
• correction comments
• resubmission status
• assigned owner
• documents required

Permitting is too important to live in someone’s inbox.

3. Interconnection and PTO tracking

A solar project is not truly done just because panels are installed.

You need to track utility applications, approvals, inspection dependencies, PTO dates, and follow-ups.

This matters because PTO delays often delay final billing and cash collection.

4. Field mobile access

Field teams should not have to send every update through calls, texts, or scattered photo messages.

A good ERP should let crews update job status, upload photos, mark blockers, and confirm work from mobile.

5. Inventory and BOM visibility

If materials are wrong or missing, the schedule breaks.

Your ERP should help track project materials, BOMs, equipment readiness, substitutions, and job costing.

6. Finance milestones

Finance should not have to ask operations whether a project is ready to invoice.

The system should connect project milestones to billing events.

Examples:

• deposit collected
• permit approved
• installation completed
• inspection passed
• PTO received
• final invoice ready

7. Owner dashboard

Owners should not need another meeting to understand the business.

A solar ERP dashboard should show:

• active projects
• stuck permits
• installs scheduled
• PTO pending
• revenue blocked
• overdue tasks
• margin risk
• team workload

8. Integrations

Your ERP should not become another isolated tool.

It should connect with or replace parts of your existing stack depending on your needs: CRM, accounting, design tools, email, file storage, and reporting.

Common mistakes solar installers make when choosing ERP

Mistake 1: Buying software only for sales

Sales software is important. But if the company is already closing deals, the real bottleneck may be delivery.

A faster proposal does not fix a broken permit queue.

Mistake 2: Choosing the biggest ERP too early

A full enterprise ERP can be powerful, but it can also slow the team down if the company is not ready for that level of implementation.

The best ERP is the one your team can actually use.

Mistake 3: Ignoring field adoption

If the field team does not update the system, your office dashboard becomes fiction.

Mobile access is not a bonus. For solar teams, it is core infrastructure.

Mistake 4: Keeping finance separate from operations

Finance should not be the last team to know what happened.

If project milestones do not trigger billing visibility, cash gets delayed.

Mistake 5: Treating spreadsheets as harmless

Spreadsheets are flexible. That is why teams love them.

But as the company grows, flexibility becomes inconsistency. Every project manager tracks differently. Every status update needs explanation. Every report takes manual cleanup.

At some point, the spreadsheet is no longer saving time. It is hiding the real cost of disorganized operations.

So, which solar ERP should you choose?

Here is the practical answer.

Choose SolarSuccess by Blu Banyan if you want a NetSuite-based solar ERP and have the budget, team, and implementation maturity for it.

Choose Scoop Solar if your biggest need is field operations, workflow execution, and connecting existing systems.

Choose Sitetracker if you are managing larger renewable infrastructure projects and need asset lifecycle management.

Choose Aurora Solar, OpenSolar, or SurgePV if your main need is design, proposal, modeling, and sales workflow.

Choose Solar1 if your pain is the messy middle of solar operations: the handoff from sale to design, permit, install, inspection, interconnection, PTO, invoice, and reporting.

That is the part of the business where margin often leaks quietly.

Not in one big failure.

Usually in small delays:

• one permit comment missed
• one field update sent to the wrong place
• one install scheduled before materials are ready
• one PTO follow-up forgotten
• one invoice delayed because finance did not know the milestone was complete

A good solar ERP should make those leaks visible before they become expensive.

Where Solar1 fits

Solar1 is being built for solar installers that have outgrown scattered operations.

The idea is not to give your team another tab to check.

The idea is to connect the work that already decides your margin:

• sales handoff
• site survey
• design status
• permit queue
• AHJ requirements
• field updates
• inventory readiness
• interconnection
• PTO
• invoice milestones
• owner reporting

Solar1’s point of view is simple:

Solar companies should not need five tools and three spreadsheets to know where a project stands.

If your team is managing projects through disconnected CRMs, spreadsheets, WhatsApp messages, and accounting notes, the cost is probably already there. It is just not clearly visible yet.
