Expert Verified — Written by Keyur Rakholiya, SurgePV Editorial. 11 tools tested for solar energy management. Pricing verified July 2026. Based on 1+ GW of delivered projects across 50+ countries.
Solar used to be simple: size the array, sell the kilowatt-hours, done. That model is dying. Net metering cuts, time-of-use (TOU) rates, and demand charges now decide whether a project pencils. The software that wins in 2026 manages energy, not just panels.
We tested 11 solar energy management software tools against real workflows. We sized batteries against TOU tariffs, modeled self-consumption for homes and factories, and checked which savings claims survive scrutiny. This list ranks what actually works, with honest weaknesses for every tool. That includes our own product.
If you need live plant monitoring rather than pre-construction energy modeling, see our separate list of solar monitoring software. This post covers the design-and-economics side: battery sizing, tariff engines, dispatch strategy, and self-consumption.

1. Energy Toolbase — Best Energy Management Software for C&I Storage Economics
Energy Toolbase (ETB) is the closest thing this category has to a center of gravity. It models storage economics pre-sale, then dispatches real batteries post-install through Acumen EMS.
What It Does Well
The rate database is the foundation. ETB maintains 70,000+ utility rates across 1,200+ territories with an in-house rates team. Savings math built on stale tariffs dies in due diligence; ETB’s survives it.
Acumen EMS closes the loop most competitors leave open. It forecasts 24 hours ahead, regenerates every 15 minutes, and dispatches hardware from Tesla, SolarEdge, Sungrow, Dynapower, and others. Demand charge reduction, TOU arbitrage, and self-consumption stack in 1 model.
Customer evidence is strong. SunGreen Systems cut proposal time from 16 hours to 1 to 2 hours, per ETB’s published case data. Over 1,500 distributed energy organizations use the platform (Energy Toolbase, 2026).
Our Take: If a project’s payback hinges on demand charges or arbitrage, ETB is the most defensible modeling tool we tested. It has no design capability at all, so budget for a second tool.
Where It Falls Short
There is no native solar design; you import 8760 data from HelioScope, Aurora, or PVsyst. No CRM integration yet, no mobile apps, and Acumen EMS pricing requires a quote. Public third-party reviews are scarce.
Key Features
- 70,000+ utility rates maintained in-house
- Solar + storage NPV, IRR, payback, and cash flow
- Acumen EMS live battery dispatch, hardware-agnostic
- NEM 1.0, 2.0, and 3.0 modeling
Pricing
- ETB Developer: $199/user/month — 10% annual discount
- Acumen EMS and ETB Monitor: Priced per project, contact sales
Who Should Use Energy Toolbase
Strong fit: C&I developers, ESCOs, and storage-heavy projects where savings math must survive scrutiny. Probably not right for: Residential installers wanting an all-in-one, or teams needing design tools.
2. HOMER — Best Energy Management Software for Microgrids and Off-Grid Hybrids
HOMER started at the National Renewable Energy Laboratory (NREL) in 1993 and now runs under UL Solutions. Over 250,000 users in 190+ countries (HOMER Energy, 2026) treat it as the default for hybrid system optimization.
What It Does Well
The chronological simulation is the core strength. HOMER Pro models a full year in time steps down to 1 minute, then tests thousands of system combinations to find the least-cost mix of solar, wind, batteries, hydro, and generators.
HOMER Grid brings the same logic behind the meter. It handles complex tariffs, EV charging plans, and resilience analysis for grid-connected facilities. NASA climate data covers any location on Earth.
Capterra reviewers rate HOMER 4.4 out of 5, and its NREL origins give it academic credibility no competitor matches. For a mine, island, or telecom site, it is the reference tool.
Our Take: Nothing else optimizes hybrid microgrids with this rigor. Accept the Windows-only desktop and the learning curve, or look elsewhere.
Where It Falls Short
Windows-only, single-user licenses, and no cloud collaboration. The interface takes real effort to learn, and users on Capterra flag the price as high versus lighter tools. There is no design or CAD capability.
Key Features
- Chronological simulation from 1-minute to 1-hour steps
- HOMER Optimizer for least-cost system search
- Multi-technology support: PV, wind, storage, hydro, CHP, hydrogen
- Sensitivity and multi-year analysis modules
Pricing
- HOMER Pro: From $125/month — add-on modules $6–$15/month each
- HOMER Grid: Custom pricing, contact sales
- Free trial: Available
Who Should Use HOMER
Strong fit: Engineers and consultants designing microgrids, off-grid systems, and hybrid plants. Probably not right for: Residential sales teams, Mac shops, and anyone wanting a plug-and-play tool.
3. PVsyst — Best Energy Management Software for Bankable Storage Simulation
PVsyst is not an energy management product by design. It earns this rank because financed storage projects still quote from its numbers, 30+ years after launch.
What It Does Well
Lenders trust PVsyst. P50, P90, P95, and P99 uncertainty analysis is built in, and most financiers require exactly that. Billions of dollars in solar projects have closed on PVsyst reports.
Storage modeling is detailed and getting deeper. The tool simulates battery behavior, self-consumption strategies, and grid injection limits with hourly resolution. Version 8 adds unlimited orientations and sub-hourly clipping correction.
The component database holds 14,000+ modules and 4,500+ inverters (PVsyst, 2026). G2 reviewers rate its design and engineering depth 9.4 out of 10, the highest in the category.
Our Take: Use PVsyst to prove the storage economics, then present them with a tool built for humans. It wins on credibility and loses on everything customer-facing.
Where It Falls Short
The interface is dated, and ease of use scores 7.1 out of 10 on G2. Windows-only, no cloud, no collaboration, and no customer-facing output. The learning curve is steep even for engineers.
Key Features
- P50/P90/P95/P99 bankable uncertainty analysis
- Detailed battery, self-consumption, and loss modeling
- 14,000+ modules and 4,500+ inverters in the database
- Batch processing and PVsystCLI automation
Pricing
- Professional: CHF 700/year (~$775) — volume discounts from 2 licenses
- Free trial: 30 days, full features
Who Should Use PVsyst
Strong fit: Engineers and developers modeling financed C&I or utility-scale solar plus storage. Probably not right for: Sales teams and anyone needing polished proposals or live dispatch.
4. PV*SOL — Best Energy Management Software for Whole-Home Energy Modeling
PV*SOL, from Berlin-based Valentin Software, models the modern electrified home better than anything else we tested. PV, battery, EV, and heat pump loads sit in 1 simulation.
What It Does Well
The 2026 version assigns individual tariffs per consumer. A household, an EV, and a heat pump can each carry their own rate structure. That mirrors how real electrified homes actually buy energy.
The component database is deep: 21,000+ modules, 5,100+ inverters, 1,900+ battery systems, and 1,600+ EVs (Valentin Software, 2026). Battery aging and cycle life simulation run at 8,760-hour resolution with Meteonorm 9 climate data.
Ease of use beats the engineering-grade competition. G2 comparative ratings put PV*SOL at 8.1 out of 10 for usability versus 7.1 for PVsyst. Pricing at €845 per year undercuts PVsyst by half or more.
Our Take: For German-style self-consumption projects with batteries, EVs, and heat pumps, PV*SOL is the sharpest model per euro. Desktop-only architecture is the tax you pay.
Where It Falls Short
Windows-only, no cloud, no mobile. Valentin explicitly warns against using it for arbitrage optimization. The 3D mode caps at 10,000 modules, and financial analysis scores 6.9 out of 10, well behind PVsyst.
Key Features
- PV + battery + EV + heat pump in 1 model
- Individual tariffs per consumer (2026 version)
- Battery aging and cycle life simulation
- 3D shading with CAD and LIDAR import
Pricing
- PV*SOL Premium 2026: €845/year — named user license
- PV*SOL Online: Free, basic calculations only
- Free trial: 30 days
Who Should Use PV*SOL
Strong fit: Engineers and installers modeling self-consumption for homes and small commercial sites. Probably not right for: Utility-scale work, arbitrage-focused storage, and Mac or cloud teams.
5. SurgePV — Best Energy Management Software for the Design-to-Savings Workflow
Full disclosure: we build SurgePV. We ranked it #5 because dedicated energy management tools go deeper on batteries and tariffs. For installers whose energy management problem is really a savings-credibility problem, this is where we are strongest.
What It Does Well
Most savings estimates break before they start. The designer models shading in 1 tool, the salesperson re-types the number into another, and the promised savings drift from the simulated reality. Customers notice when the first bill arrives.
SurgePV removes the handoff. You design the 3D rooftop, run physics-based shadow analysis, and pull generation plus payback, internal rate of return (IRR), and net present value (NPV) from the generation and financial tool. Cash, loan, lease, and power purchase agreement (PPA) scenarios run side by side.
The proposal layer turns those figures into a branded document, and Clara AI speeds up the copy. Because it is cloud-only, the whole team works from the same numbers. For a residential or small commercial quote, the full flow takes under 10 minutes in our testing.
Our Take: If your energy management pitch dies because sales and engineering quote different savings, SurgePV fixes the root cause. It is not a battery dispatch engine, and we do not pretend it is.
Where It Falls Short
SurgePV has no native battery dispatch simulation and no 8760-hour tariff engine. Demand charge modeling and TOU arbitrage need a dedicated tool like Energy Toolbase. There is no CRM and no live system control.
Key Features
- 3D rooftop design with string sizing and a module plus inverter database
- Physics-based shadow analysis feeding generation estimates
- Payback, IRR, and NPV across cash, loan, lease, and PPA
- Branded solar proposals built from live design data
Pricing
- For 3 Users plan: $1,899/year — design, simulation, financials, and proposals included
- Free trial: Available with full capabilities
Who Should Use SurgePV
Strong fit: Installers and EPCs who need credible savings figures for solar proposals, residential through commercial. Probably not right for: Storage-first C&I deals needing tariff engines or live dispatch.

6. Aurora Solar — Best Energy Management Software for Residential Sales With Storage
Aurora Solar is the reference platform for US residential solar sales, with 7,000+ companies on board. Its storage modeling sits inside the sales workflow rather than beside it.
What It Does Well
Speed is the pitch. Aurora’s Sales Mode turns designs into proposals in under 3 minutes, and battery storage options ride along in the same flow. Reps quote solar plus storage without touching a second tool.
The LIDAR-assisted 3D modeling and automated shading feed real production numbers into every savings estimate. G2 reviewers rate Aurora 4.6 out of 5, with 3D visualization scoring 9.5 out of 10.
For a sales manager running a large team, the permissions, integrations, and contract management justify the enterprise tier. Energy management here means giving the homeowner a credible bill-savings story fast.
Our Take: Aurora is the safest pick for a funded US residential sales org selling storage. You pay a premium, and reps still need to verify automated roof models before trusting the savings math.
Where It Falls Short
Pricing is unpublished and reviewers call it expensive for small teams. Automated modeling misses obstructions often enough that verification is mandatory. Storage economics lack the depth of Energy Toolbase for complex tariffs.
Key Features
- Sales Mode proposals in under 3 minutes
- Battery storage options inside the sales flow
- LIDAR-assisted 3D modeling and shading
- Contract management with e-signature
Pricing
- Foundation, Build, Grow, Scale: Custom pricing, contact sales
- Free trial: Guided demo only
Who Should Use Aurora Solar
Strong fit: US residential sales teams of 10+ reps selling solar plus storage at volume. Probably not right for: Solo installers, non-US markets, and C&I storage economics work.
7. OpenSolar — Best Free Energy Management Software
OpenSolar is the only genuinely free platform on this list. 28,000+ users in 185+ countries (OpenSolar, 2026) pay nothing for design, battery modeling, tariffs, and proposals.
What It Does Well
The price is the headline: $0 forever, unlimited projects and users. OpenSolar monetizes hardware partners and lenders instead of installers. That makes it the default starting point for new solar businesses.
Battery and tariff modeling come included. Users set self-consumption and backup scenarios, apply local tariffs, and show savings in interactive proposals. Speed is real: proposals in under 2 minutes once templates exist.
Accuracy is third-party validated by PV Evolution Labs (PVEL) and a US government agency. For a budget-constrained installer learning energy management sales, nothing else comes close at $0.
Our Take: For a 1 to 10 person installer, OpenSolar’s free energy modeling is unbeatable value. Know the ceiling: it tops out around 500 kW and lacks engineering depth.
Where It Falls Short
The 500 kW cap rules out large C&I. Photogrammetry-based modeling is less precise than LIDAR, and there is no offline mode. Complex tariff stacking and demand charge work exceed its depth.
Key Features
- Free 3D design with battery scenarios
- Tariff and savings modeling in proposals
- Built-in CRM, payments, and lender integrations
- Full iOS and Android apps
Pricing
- Free tier: $0 — unlimited projects, users, and features
- Free trial: Not needed; the product is free
Who Should Use OpenSolar
Strong fit: New and small residential installers, budget-conscious teams, emerging markets. Probably not right for: C&I above 500 kW, complex tariff work, and bank-grade engineering needs.
8. SAM — Best Free Energy Management Software for Deep Modeling
The System Advisor Model (SAM) is NREL’s free, open-source techno-economic engine. Over 150,000 users in 190+ countries (NREL, 2026) run it for research, feasibility, and policy work.
What It Does Well
The physics and finance depth is remarkable for $0. SAM models lithium-ion, lead-acid, and flow batteries behind or in front of the meter. Parametric, sensitivity, and Monte Carlo analysis come standard.
Weather data pulls automatically from the National Solar Radiation Database (NSRDB). Financial models cover residential, commercial, and utility-scale structures with cost data from NREL’s Annual Technology Baseline.
It runs on Windows, macOS, and Linux. The software development kit lets developers embed SAM’s simulation core in their own applications, which many commercial tools quietly do.
Our Take: SAM is the best free way to pressure-test any vendor’s savings claim. Budget real learning time, and expect a desktop experience built for analysts, not salespeople.
Where It Falls Short
The interface assumes technical fluency, and there is no proposal or CRM layer. No cloud collaboration, no mobile apps, and no live dispatch. Support comes through forums and bi-weekly round tables, not an account manager.
Key Features
- Free and open source, funded by the US Department of Energy
- Detailed battery models behind and in front of the meter
- Parametric, sensitivity, and Monte Carlo analysis
- SDK for custom integrations in Python, C#, and more
Pricing
- SAM: $0 — free with email registration
- Free trial: Not needed; the product is free
Who Should Use SAM
Strong fit: Engineers, analysts, researchers, and developers validating project economics. Probably not right for: Sales teams and anyone needing proposals or quick turnaround.
9. Solargraf — Best Energy Management Software for NEM 3.0 Residential
Solargraf, owned by Enphase since 2021, built its energy management story around California’s Net Energy Metering (NEM) 3.0 shift. Under NEM 3.0, export rates collapsed, and self-consumption math now decides every deal.
What It Does Well
The NEM 3.0 modeling uses California Public Utilities Commission (CPUC) hourly sell rates. That granularity matters because a battery’s value swings wildly by hour under the current tariff. Solargraf sizes storage against that reality.
Battery support covers Enphase IQ Batteries, Tesla Powerwall, and 25+ manufacturers, with backup scenario comparisons. The Good/Better/Best proposal format presents 3 storage options in 1 document.
Permitting is included, with AHJ-compliant packages and validated single-line diagrams. For California residential shops, quote through permit lives in 1 subscription.
Our Take: For California residential storage sales, Solargraf’s NEM 3.0 depth justifies the price. Verify its shading output against a second tool before trusting production-driven savings claims.
Where It Falls Short
Shading accuracy is the most common user complaint, and some teams cross-check in Aurora or HelioScope. No built-in CRM, annual billing only, and the NEM 3.0 depth matters little outside California.
Key Features
- NEM 3.0 optimization with CPUC hourly rates
- Battery modeling for 25+ manufacturers
- Good/Better/Best multi-option proposals
- DIY permit packages with validated diagrams
Pricing
- Starter: $2,799/year — 240 projects, 2 users
- Free trial: Available; new users get 120 project credits
Who Should Use Solargraf
Strong fit: California residential installers selling batteries under NEM 3.0. Probably not right for: Teams needing shading precision guarantees or non-US markets.
10. Enact — Best Energy Management Software for TOU Battery Sizing
Enact Solar serves 1,000+ users across 25+ countries and processes $1.5 billion+ in annual projects. Its January 2026 acquisition of PVComplete added permit-grade engineering to the platform.
What It Does Well
The battery workflow is the draw. Enact models TOU rate optimization, visualizes charge and discharge cycles, and recommends storage sizes against self-consumption and time-based discharge modes.
The two-sided platform is unique on this list. Installers design and sell; end customers track performance, savings, and payoff in the Enact Home app. The “actual versus estimated” generation comparison keeps savings promises honest after install.
Entry pricing is accessible at $199 per month for up to 3 users. Design-as-a-Service delivers outsourced designs in 24 hours for teams short on engineering capacity.
Our Take: Enact is a practical pick for small and mid-size installers who want TOU battery sizing plus post-install accountability. Thin third-party review coverage means you should trial it on real jobs first.
Where It Falls Short
No G2, Capterra, or TrustRadius listings, so independent validation is limited. DSM-based 3D modeling depends on geographic coverage. No free tier, and enterprise pricing requires a sales call.
Key Features
- TOU rate optimization with battery cycle visualization
- Self-consumption and time-based discharge modes
- Customer-facing app with savings tracking
- PVCAD permit-ready engineering tools
Pricing
- Platform Entry: $199/month — up to 3 users
- PVCAD Bundle: $245/month — includes AutoCAD license
- Free trial: Available
Who Should Use Enact
Strong fit: Small and mid-size installers selling storage against TOU rates. Probably not right for: Teams wanting a free tool or deep independent review data before buying.
11. SolarPlus — Best Energy Management Software for Home Energy Automation
SolarPlus is an Australian platform used by 1,700+ solar sales companies, with 450,000+ systems quoted and $4 billion+ designed. Its Version 5 engine pushes past solar plus batteries into whole-home energy.
What It Does Well
The simulation engine models hot water, EV smart chargers, and load shifting alongside solar and storage. It shows how multiple savings streams stack, which matches how Australian households actually cut bills.
Peak demand reporting and peak shaving analysis give commercial work real depth. Preloaded consumption profiles and tariffs speed up the modeling. The built-in CRM tracks the sale from enquiry to installation.
Compliance documentation is the traditional strength. Job handoff packs, commissioning forms, and customer handover manuals generate from the same data.
Our Take: For Australian installers selling electrification rather than just solar, SolarPlus models the whole bill. Pricing opacity and monthly fees with user caps are the trade-offs.
Where It Falls Short
Pricing is not published and adds up with per-user mapping fees. Detailed third-party reviews are scarce, and the platform’s depth concentrates on the Australian market. International tariff coverage trails US-focused tools.
Key Features
- Hot water, EV, and load-shifting simulation
- Peak demand reporting and peak shaving
- Built-in CRM and proposal templates
- Compliance and handover documentation
Pricing
- Subscription: Custom, based on business size — mapping add-ons from $8/site
- Free trial: Contact sales
Who Should Use SolarPlus
Strong fit: Australian installers selling solar, batteries, and home electrification packages. Probably not right for: Teams wanting transparent pricing or deep non-Australian tariff support.

- US residential sales team selling storage at volume: Aurora Solar, or Solargraf for California NEM 3.0 work.
- New installer on a budget: OpenSolar for the free platform, SAM for free deep validation.
- Installer selling TOU-optimized batteries with post-install tracking: Enact.
The Myth of the All-in-One Energy Management Tool
Here is the contrarian truth from a decade of EPC work: no single tool does energy management end to end. Vendors imply otherwise, and buyers learn the hard way.
Modeling and dispatch are different jobs. A pre-sale simulation estimates what a battery would do. An energy management system controls what a battery does do, second by second, against live prices and loads. Energy Toolbase is the rare vendor that does both, and even it splits those into separate products.
The stack that works in 2026 looks like this. Design and shading in a solar design software tool. Savings and storage economics in a modeling tool. Dispatch in a hardware-connected EMS. Monitoring in whatever the inverter fleet supports; our monitoring software list covers that side.
You can compress that stack, but only at the edges. SurgePV merges design, shading, generation, and financials into 1 workflow, which kills the most common error: sales quoting savings the engineer never simulated. What you should not compress is the tariff engine. If the savings claim rests on demand charges or TOU arbitrage, only a maintained rate database keeps that promise honest.
Pro Tip
Take your last 3 signed storage deals and re-model them in any trial. If the tool’s savings figure lands within 10% of the customer’s actual first-year bills, trust it. If not, walk away before your reputation does the walking.
How to Choose Solar Energy Management Software
Evaluate any tool against these 6 dimensions before you commit.
- Where the savings number comes from. Estimates built on your real design and shading data beat typed-in assumptions. Errors in savings promises cancel contracts.
- Tariff depth. Ask who maintains the rate database and how often it updates. A stale TOU schedule can flip a storage project’s payback by years.
- Battery realism. Check whether the tool models degradation, round-trip efficiency, and dispatch strategy, or just subtracts a flat percentage from the bill.
- Modeling versus control. Decide if you need pre-sale simulation, live dispatch, or both. They are different products with different prices.
- Lender acceptance. Financed projects need P90 figures from tools lenders recognize. PVsyst is the default; DNV-validated tools also pass.
- Total cost per project. Divide the annual subscription by your project volume. Free tools win at low volume; flat subscriptions win at high volume.
Conclusion
The right solar energy management software depends on what you sell and whose savings claim you sign. Energy Toolbase leads for C&I storage economics. HOMER leads for microgrids. PVsyst leads for bankable simulation. SurgePV is the practical pick for installers who need design, shading, and credible savings figures in 1 workflow.
Do these 3 things this week:
- Shortlist 2 or 3 tools from the decision flowchart that match your segment.
- Re-model your last signed storage or self-consumption deal in each trial.
- Compare each tool’s savings figure against the customer’s actual bills, then buy the closest one.

Frequently Asked Questions
What is solar energy management software?
Solar energy management software models and controls how solar power, batteries, and grid energy interact. It covers battery sizing, tariff optimization, self-consumption analysis, and in some tools live dispatch of storage systems.
What is the best solar energy management software in 2026?
Energy Toolbase leads for commercial storage economics and live battery dispatch. HOMER leads for microgrids and off-grid hybrids. PVsyst leads for bankable storage simulation. SurgePV is the best fit for installers who need design, shading, and financials in 1 workflow.
Is there free solar energy management software?
Yes. NREL’s System Advisor Model (SAM) is free and open source, with battery storage and financial models. OpenSolar offers free design with battery and tariff modeling. Both trade depth for cost.
How much does solar energy management software cost?
Prices range from free (SAM, OpenSolar) to $125 per month (HOMER Pro) and $199 per user per month (Energy Toolbase). Live energy management systems like Acumen EMS are priced per project.
Can design software replace a dedicated energy management system?
For pre-sales modeling, usually yes. Tools like PV*SOL, Aurora, and SurgePV estimate self-consumption and savings accurately enough for proposals. Live dispatch of a running battery still needs a real energy management system on site.
What is the difference between monitoring and energy management software?
Monitoring software reports what a system did. Energy management software decides what a system should do: when to charge, when to discharge, and which value stream to prioritize. Some platforms do both.
