Quick Verdict
Our Verdict
PV*SOL and Energy Toolbase are complementary tools, not competitors. PV*SOL designs and simulates PV systems with detailed shade analysis and energy modeling. Energy Toolbase models the financial case for energy storage projects using real utility rate data. If you need both solar design and storage financial modeling with customer-facing proposals, SurgePV is a more complete alternative.

Core Capabilities
PV*SOL: Design + Simulation
PV*SOL is a dedicated solar design and simulation tool. You build a 3D model of the project site, place panels, define obstructions, and run detailed energy yield simulations with minute-level shade resolution. The software calculates how much energy the system produces, how much the building consumes, and how battery storage affects self-consumption rates.
Where PV*SOL stands out is its integrated energy system modeling. The software simulates the interplay between solar panels, battery storage, EV chargers, and heat pumps in a single simulation environment. For European residential markets where feed-in tariffs are declining and self-consumption is the primary economic driver, this integrated approach is valuable.
PV*SOL does not model complex utility rate structures, demand charges, or time-of-use optimization. Its economic analysis uses simplified tariff inputs — fine for flat-rate European markets, but insufficient for complex US commercial rate structures.
Energy Toolbase: Financial Modeling + Dispatch
Energy Toolbase is not a design tool. It doesn’t place panels, model roofs, or calculate shade losses. What it does is model the financial case for solar and storage projects with a level of rate schedule accuracy that no design tool matches.
The platform maintains 100,000+ utility rate schedules across the US, including time-of-use rates, demand charges, tiered structures, and net metering rules. You input a solar production profile (from any design tool), define a storage system, and Energy Toolbase calculates the exact bill savings, demand charge reductions, and payback period under the customer’s actual rate plan.
Energy Toolbase’s Acumen EMS takes this further — it’s a real-time battery dispatch controller that optimizes when the battery charges and discharges based on live rate conditions. This bridges the gap between modeling and operations, something no other tool in this comparison offers.
The limitation: Energy Toolbase is US-centric. Its rate databases and financial models are built for US utility structures. International teams will find limited value.

Best Alternative: SurgePV
PV*SOL handles design and simulation but lacks financial sophistication. Energy Toolbase handles storage economics but can’t design a system. Neither produces customer-facing proposals or engineering documentation.
SurgePV is a cloud-based solar design software that bridges these gaps:
- Design, simulate, and propose in one workflow
- 8760-hour shade simulation with detailed yield analysis
- Financial modeling with cash, loan, lease, and PPA structures
- Multi-currency support for global projects
- Native SLD and three-line diagrams — no AutoCAD needed
- Branded proposal generation in web and PDF formats
- Residential, commercial, and utility-scale projects
- Cloud-based on any device, any OS
- $1,499/year with all features on every plan
Instead of pairing PV*SOL for design with Energy Toolbase for financials, SurgePV provides both capabilities plus proposal generation and engineering documentation — in a single subscription.
Design and Model Finances in One Platform
SurgePV combines solar design, simulation, financial modeling, and proposals at $1,499/year.

Frequently Asked Questions
Is PV*SOL better than Energy Toolbase?
They do completely different things. PV*SOL is a desktop 3D simulation tool for designing and modeling PV systems with battery, EV, and heat pump integration. Energy Toolbase is a financial modeling platform for storage projects with 100k+ utility rate schedules. There is almost no feature overlap between them.
Does Energy Toolbase do solar design?
No. Energy Toolbase is a financial modeling and energy storage dispatch tool. It does not design solar panel layouts, perform shade analysis, or generate engineering drawings. You need a separate design tool like PV*SOL or SurgePV for solar system design.
Can PV*SOL model utility rate structures?
PV*SOL includes basic economic analysis with simplified tariff inputs, but it does not have a comprehensive utility rate database. Energy Toolbase maintains 100,000+ utility rate schedules and models time-of-use, demand charges, and net metering with precision.
Which is better for battery storage projects?
PV*SOL simulates residential battery dispatch for self-consumption optimization. Energy Toolbase models commercial and utility-scale storage economics, including its Acumen EMS for real-time dispatch control. For residential batteries, PV*SOL. For commercial storage economics, Energy Toolbase.
Is there one tool that does design and financial modeling?
Yes. SurgePV combines solar design, simulation, financial modeling with multi-currency support, proposal generation, and electrical engineering in one cloud platform at $1,499/year.
Can I use PV*SOL and Energy Toolbase together?
Some teams do use both — PV*SOL for system design and simulation, then Energy Toolbase for detailed storage financial analysis. However, there is no direct integration between the two tools, so data must be transferred manually.
