Utilities

Features & Capabilities

PV Optimizer & Solar Compass is a free Chrome extension that helps maximize solar panel output. Use it by selecting one of four available time frames, position your device above the panels, and adjust azimuth and tilt using values from the app. The optimizer's algorithm aims to extract every watt and minimize missed opportunities.

The included Solar Compass provides real-time solar position and radiation data, and version 2.0 adds a forecast feature: input your panel capacity, tilt, and azimuth to get a monthly energy forecast. All features are free to use.

User Reviews

Pros: The app is valuable for aligning solar panels, offering an effective position/orientation optimizer, location and irradiance data to estimate production, and ROI calculations. It’s free and widely used for regular tuning. Cons: Multiple reviews report crashes and stability problems, especially on iOS, plus gyroscope connectivity issues. Other recurring problems include data download errors, odd azimuth/tilt outputs, and a yearly-output graph that lacks decimals. Users also request more time-based views and better nighttime alignment tips. Overall, PV Optimizer is useful and appealing for planning and setup, but reliability bugs significantly impact consistent use.

Pros

Strong alignment/angle optimization feature that reduces setup guesswork
Location and irradiance data help estimate power generation
ROI calculation and solar installation planning
Free to use
Useful for regular tuning and alignment

Cons

Frequent crashes and instability on iOS
Gyroscope connectivity/off issues affecting alignment
Data download errors prevent the app from working
Azimuth/tilt readings can be inaccurate or odd
Yearly output graph scale lacks decimal precision

Can’t use angle solar panel option anymore. Error- iPhone gyroscope off. My gyroscope works with other apps My iPhone is updated & app is updated. I tried deleting app & reinstall, still not working. Any help to resolve would be appreciated

This is the best app I have used for finding optimal setup angles for our portable solar suitcases. The location and irradiance info help in estimating power generation so we can better budget usage. The position optimizer feature takes out most of the guesswork out of setup. A selection for a shorter time period like a day or week would make this app perfect for portable panel setup.

I use this every so often to align my panels. It would be nice though if the alignment tool adjusted to the time setting that you have set up. Sometimes it would be nice to adjust the panels at night.
