<!-- section:executive-snapshot -->
## Executive Snapshot
**What it is:** Solar System Calculator is a utility app for RV and cabin owners that calculates battery, panel, and inverter requirements for off-grid energy systems.
**Why users hire it:** It removes the cognitive friction of manual load estimation by converting monthly utility bill data into specific hourly Watt consumption values.
<!-- /section:executive-snapshot -->

<!-- section:features -->
## App DNA (Features & Intent)
- **[Differentiator] Consumption Calculator:** Converts monthly kWh bill data into hourly Watt consumption values.
- **[Differentiator] PDF Reporting:** Generates corporate-style reports with cost analysis and system requirements.
- **[Standard] Device Management:** Input power, quantity, and usage duration for individual appliances to calculate total load.
<!-- /section:features -->

<!-- section:market-position -->
## Market Position {#market-position}

Solar System Calculator operates as a niche utility tool within the Business category. With zero ratings and no updates in 305 days, the app lacks the momentum required to compete with active web-based solar calculators.
<!-- /section:market-position -->

## Monetization Strategy
- **Model:** Freemium
- **Tiers:** Free version with banner and rewarded ads, Pro version (ad-free with custom reporting)
- **Analysis:** The freemium model uses rewarded ads to gate PDF report generation, pushing power users toward the ad-free Pro version.

<!-- section:swot -->
## SWOT Analysis {#swot}

**Core Strengths:**
- Consumption calculator automates complex load math

**Growth Levers:**
- Add direct-to-retailer referral links for hardware


<!-- /section:swot -->
<!-- section:momentum -->
## App Momentum (Zombie) {#momentum}

- No updates in 305 days.
- Maintenance-mode status since October 2025.

> **Cadence:** 1 total versions · 0 majors in last 6 months · 305 days since last update

<!-- /section:momentum -->

<!-- section:so-what -->
## The "So What?" (Strategic Takeaway) {#so-what}

Solar System Calculator is a business app that is free with in-app purchases.

<!-- speakable-start -->
> **Bottom Line:** Solar System Calculator provides a useful utility, but its 305-day update gap suggests a project in maintenance mode. Resuming a release cadence with updated hardware cost data would prevent the tool from becoming obsolete against faster web-based competitors.
<!-- speakable-end -->

**Best for:** RV and boat owners, cabin enthusiasts, and solar energy technicians.

<!-- section:pm-actions -->
### PM Action Plan (Next Best Moves)

- [ ] [MAINTAIN] Ship a minor update with current hardware pricing data because the app is dormant for 305 days → restore basic utility
<!-- /section:pm-actions -->

<!-- section:outlook -->
### Outlook: Declining

The market for off-grid planning tools is shifting toward web-based calculators that provide instant, ad-free results. Solar System Calculator's lack of development activity leaves it exposed to these faster alternatives, and without a return to active maintenance, the app will likely continue to lose relevance.

- 🔴 The 305-day update gap indicates a dormant project, which erodes user trust and search visibility over time.
