Commercial Solar + Storage
Proposals, Done For You.
Send us the project. WattFlow does the analysis. Skip the steep learning curve of pro modeling tools and the per-project consulting fees. One flat subscription gets you customer-ready proposals — sizing, savings, payback, incentives, and scenarios — built by WattFlow and delivered within 5 business days.
How It Works
Three simple steps. You provide the project, we deliver the proposal.
1 — Send Us the Project
Subscriber submits project info through the Full Service intake form: customer/site info, utility bills, interval data if available, solar & battery equipment, pricing, objectives, financing assumptions, and notes.
2 — WattFlow Does the Analysis
We review the information and build the project on the WattFlow platform: battery sizing, kW/kWh, peak-demand reduction, demand-charge savings, solar+storage or standalone analysis, arbitrage, cash flow, payback, ROI, incentives, and alternative scenarios.
3 — Receive Your Proposal
You receive the completed WattFlow proposal, ready to use with your customer. If bills or details are insufficient, we may request a little more information.
WattFlow remains equipment-neutral unless you request a specific manufacturer.
A proposal your customer can say "yes" to
No templates, no boilerplate. Each deliverable is built around your specific project data and customer objectives — ready to send.
Optimized kW / kWh sizing
Battery capacity and power tuned to your customer's load and rate structure — not a one-size spec sheet.
Peak-demand & bill savings
Transparency on demand-charge reduction, energy arbitrage, and year-by-year savings projections.
Simple payback, ROI & cash flow
The financials decision-makers actually ask for: payback, 20-year NPV, IRR, and cash-flow timeline.
Incentives & credits applied
Federal ITC, MACRS bonus depreciation, and state/utility incentives modeled into the numbers.
Customer-ready presentation
A polished, branded proposal you can hand straight to the customer — no reformatting required.
Scenario & sensitivity runs
Alternative sizing and financing scenarios so your customer sees the options, not just one number.

Stop Paying Every Time You Need a Proposal
Many commercial solar & storage providers use one or both of two models: expensive software subscriptions where the installer still does the modeling, or consulting services that charge hundreds per project. WattFlow is different — one flat $50 monthly subscription, or free if you do it yourself.
| WattFlow Full Service | Traditional Modeling Software | Pay-Per-Project Consulting | |
|---|---|---|---|
| Monthly cost | $50 | Often hundreds/month | Varies |
| Per-proposal fee | $0 | May have limits | Often hundreds/project |
| You perform the analysis | No | Yes | No |
| Software learning curve | Minimal | Often significant | None |
| Unlimited requests | Yes* | Often limited | No |
| DIY option | Free | Usually paid | No |
*Subject to WattFlow's reasonable-use policy. No competitor pricing is published above except WattFlow's own.
"Other platforms may charge for software access and professional modeling services separately. WattFlow gives contractors another option: use WattFlow yourself for free, or have WattFlow do the project for one flat monthly subscription."
WattFlow is Free.
