WHAT WE DO
We turn solar data into proposals that close — and reports that finance.
PremiumCAD operates at the intersection of solar engineering and sales excellence. We produce the full spectrum of solar proposal and simulation deliverables — from bankable PVsyst energy yield studies for institutional lenders to stunning branded Aurora Solar proposals that homeowners sign at the kitchen table.
Your sales rep should be presenting — not building proposals. We handle every design, simulation, and financial model so your team focuses on the customer conversation.​
​
Our PVsyst simulations use site-specific meteorological data, 3D shading models, and IEC 61724-compliant loss accounting — producing P50/P90 reports that banks accept by name.
​
Every financial model accounts for NEM 3.0 export rates, federal ITC, state rebates, SGIP incentives, utility escalation, and financing structures — cash, loan, lease, and PPA.
​
We're platform-agnostic — we work in Aurora, HelioScope, OpenSolar, PVsyst, PV*SOL, and Energy Toolbase, matching whichever tool your workflow requires.

PVSYST DEEP DIVE
The gold standard for bankable solar yield analysis
PVsyst is the software lenders, independent engineers, and utilities request by name in term sheets. Here's what our PVsyst service includes — and why it matters.
Site-Specific Meteorological Data
We import location-matched irradiance data from Meteonorm 8, Solargis, PVGIS, or NASA POWER — long-term averages calibrated to your site's latitude, altitude, and climate zone. No generic regional defaults.
3D Near-Shading Scene
A full 3D model of your site built in PVsyst from dimensions, drone imagery, or coordinates — accurately simulating shadows from trees, chimneys, adjacent buildings, and horizon obstructions across every hour of the year.
Full Loss Diagram
Every energy loss quantified separately: irradiance quality, incidence angle modifier, soiling, thermal, wiring resistance, inverter efficiency, module mismatch, transformer losses, and system availability. No guesswork — every number traceable to a physical cause.
Advanced Technology Modeling
Bifacial module rear-side gain with ground albedo modeling, single-axis and seasonal tracker backtracking optimization, battery storage integration, and degradation curves over project lifetime — all modeled in a single simulation run.
IEC 61724-Compliant Report
Final report formatted for independent engineer review and lender submission — including system layout, simulation assumptions, loss waterfall, hourly production profile (8,760 data points), and P50/P90 probability curves with interannual variability bands.
FINANCIAL MODELING
Every financial metric your customer or lender needs
Our financial models are built on real utility rates, current incentive structures, and site-specific production data — not industry averages or generic assumptions.
Every financial model we produce starts with the actual utility rate schedule — not an average. We pull the correct tariff, time-of-use structure, demand charges, NEM 3.0 export compensation rates, and non-bypassable charges for each project's specific utility account, ensuring the savings projection is accurate down to the cent.
NEM 3.0 hourly export modeling — not a flat credit rate. We calculate avoided-cost compensation for each hour of the day across 12 months.​
Federal ITC (30% for commercial), SGIP rebate integration, state rebates, SREC values, and utility incentives all factored into Year 1 economics.​​
Cash, loan, lease, and PPA financing structures — with dealer fees, rate factors, escalators, and residual value modeled for each option.
25-year pro forma with utility escalation rate, system degradation curve, and O&M cost assumptions — exportable for lender or auditor review.
Payback Period
Simple and discounted payback — how many years until cumulative savings exceed system cost
NPV & Cash Flow
Year-by-year discounted cash flow and net present value at client-specified discount rate
Bill Savings
Monthly and annual utility bill reduction with NEM 3.0 export credit modeling and TOU optimization
IRR (25-Year)
Internal rate of return across the full project life — the metric CFOs and investors compare to cost of capital
LCOE
Levelized cost of energy vs. utility rate — quantifies the cost advantage per kWh over system lifetime
Incentive Breakdown
ITC, SGIP, SREC, utility rebate, and state incentive — itemized with timing and eligibility assumptions

CLIENT FEEDBACK
What installers and developers say
From one-person solar shops to development companies financing hundred-megawatt projects, here's what PremiumCAD's proposal services deliver.
"
We were building proposals manually in Excel — it was taking our reps 2–3 hours per job and the numbers were inconsistent. Since switching to PremiumCAD for our Aurora proposals, turnaround is under 4 hours and our close rate went from 28% to 47%. The financial modeling is just more convincing than what we were producing in-house.

K. Washington
Owner · Residential Solar Installer, Los Angeles
Our bank specifically required a PVsyst P90 report as part of the debt facility for our 8 MW ground-mount project. PremiumCAD delivered a report that passed independent engineer review on the first submission — no revision requests. The shading analysis from the drone survey data was exactly what the IE wanted to see.

Project Director · Solar Development Company
We do commercial rooftop work — mostly 100–500 kW systems where the CFO is the buyer. PremiumCAD's HelioScope designs paired with the Energy Toolbase financial model is exactly the package our C&I buyers need. The demand charge analysis alone has closed three deals that we would have otherwise lost on price.
