Solar Monitoring Alternatives for SunPower Owners
When SunPower went through bankruptcy, thousands of homeowners were left wondering what would happen to their system monitoring, historical data, and long-term hardware support. Fortunately, several distinct solutions have emerged to fill the gap.
Whether you want an official cloud path, a highly technical DIY local setup, a seamless plug-and-play solution, or full integration with Enphase, this breakdown covers the top four monitoring paths available right now.

Sunflower
Best for most SunPower owners who want real data without the technical setup
Sunflower connects directly to your SunPower system over your home Wi-Fi. This means you see live production data the moment you open the app.
The app shows individual panel output, battery charge and history, home consumption, and grid import/export. A panel layout map highlights underperformers, and the Insights tab lets you see trends over day, month, or year with per-panel breakdowns.
The optional Sunflower Bridge
One limitation of app-only monitoring: you only get data when you're on the same Wi-Fi network with the app open. The Sunflower Bridge is a small plug-in device that syncs your data to the cloud every 30 minutes, unlocking remote access and full historical charts from any network. It's a one-time purchase at $49.99.
Strengths
- Live data on local Wi-Fi
- Panel-level detail and layout map
- Detailed battery monitoring
- Historical data view
- Easy to set up
- Low cost — $1.99/mo or $12/yr
Limitations
- Full features require the Bridge add-on ($49.99)
SunStrong
The official app — convenient, but limited
SunStrong Connect (formerly MySunPower) is the official monitoring app for SunPower customers. It works out of the box — your system is already registered — and shows system-level production, consumption, and battery state.
Compared to the original SunPower app, SunStrong significantly changed the experience after taking over. History is aggregated to the hourly level, panel-level visibility is limited, and they've introduced a subscription fee.
Strengths
- Zero setup — already connected to your system
- Full history since you install the system
Limitations
- $99/yr or $9.99/mo subscription
- Limited panel-level detail
- SunStrong's cloud uptime unreliable from time to time
Home Assistant
Most powerful — but requires real technical investment
Home Assistant is an open-source home automation platform with community-built integrations for SunPower systems. If you're already running Home Assistant or are comfortable setting it up, it can pull data from your inverter and display it alongside the rest of your smart home.
The trade-off is complexity. You'll need a dedicated device to run Home Assistant — the official Home Assistant Green runs $199. Remote access outside your home requires an additional Nabu Casa subscription at $6.50/month or $65/year. Expect to spend time configuring the integration and troubleshooting YAML. It's a great fit for home automation enthusiasts who are comfortable with open-source software and the terminal, but steep for someone who just wants to see their solar data.
Strengths
- Highly customizable dashboards
- Integrates with the rest of your smart home
- No ongoing cost if you don't need remote access
Limitations
- Significant setup and maintenance effort
- Requires dedicated hardware ($199+ for HA Green)
- Remote access costs extra ($65/yr or $6.50/mo)
- DIY — no polished mobile app out of the box
Enphase
Full hardware replacement — most complete platform, highest cost
Enphase offers a path for SunPower owners who want a monitoring platform with a complete hardware migration: replace your SunPower PVS (monitoring gateway) with Enphase hardware, and your system is absorbed into the Enphase ecosystem. Because Enphase uses microinverters, you get per-panel visibility and detailed production data through their app and web dashboard.
The catch is the entry price. This is not a software switch — hardware replacement requires a licensed electrician or Enphase-certified installer. The process is fully handled by a contractor; you're not involved in the technical work. Depending on your system size and local labor rates, expect roughly $1,000 or more for equipment and installation. After that, Enphase Enlighten monitoring is either $9.99/month or a $249 lifetime purchase.
This path makes the most sense if your SunPower system has other hardware issues that need addressing anyway, or if you want a complete platform migration — not just a monitoring workaround.
Strengths
- Panel-level monitoring
- Remote access included
- Mature, widely-supported platform
Limitations
- Requires professional install (~$1,000+)
- Significant upfront cost and disruption
- Ongoing subscription unless lifetime plan purchased
Bottom line
For most SunPower owners, Sunflower is the best option. It requires no technical setup, shows you live data the official app can't match, and costs just $1/month. If you want the full features, the Bridge add-on is a one-time $49.99 — well below what SunStrong charges per year.
If you're already deep into home automation and running Home Assistant, the SunPower integration is worth exploring — but budget a weekend for setup. Home Assistant Green hardware runs $199, and remote access costs an extra $6.50/month if you need it outside your network.
Enphase is the right call if your SunPower hardware needs replacing anyway, or you want a full platform migration and don't mind the ~$1,000+ installation cost and contractor coordination. Once set up, Enlighten monitoring is solid — but it's a commitment, not a quick fix.
