Garmin Edge 1040 Solar GPS Bike Computer with Solar Charging & Multi-Band GNSS

The Garmin Edge 1040 Solar is the solar-charging variant of Garmin's flagship large-screen cycling computer, adding Power Glass™ solar charging technology to the already class-leading battery life of the Edge 1040. In direct sunlight, the solar lens adds up to 20 minutes of runtime per hour in standard GPS mode and up to 42 minutes per hour in battery saver mode — pushing total battery life to an extraordinary 100 hours in battery saver mode.

Beyond the solar capability, the Edge 1040 Solar shares all the core features of the standard 1040: multi-band GNSS technology for exceptional positioning accuracy under tree cover and in urban environments, ClimbPro ascent planning with real-time gradient and effort data, ride type-specific maps with searchable points of interest, and deep integration with Strava, Komoot, and TrainingPeaks® via the Garmin Connect™ app. The large, high-resolution display makes it easy to read data at a glance, even in bright sunlight.

On the training side, the Edge 1040 Solar delivers power target recommendations, stamina insights, strength and weakness analysis, and adaptive workout suggestions when paired with a compatible power meter and heart rate monitor. Missed a session? The device prompts you to reschedule and stay on track with your training plan. For ultra-endurance riders, bikepacking adventurers, and anyone who spends long days in the saddle, the solar charging capability transforms the Edge 1040 from a great computer into an almost limitless one.

If you're deciding between the Edge 1040 Unit Only and the Solar, the Solar is the clear choice for anyone regularly riding 6+ hours, touring, or bikepacking where charging opportunities are limited.

What It's Good For

• Ultra-endurance, bikepacking, and multi-day touring where charging opportunities are limited
• Power Glass™ solar charging adding up to 42 min/hr in battery saver mode — up to 100 hours total
• Multi-band GNSS for accurate positioning in forests, mountains, and urban environments
• ClimbPro ascent planning with gradient profiles and real-time pacing data on every climb
• Advanced training analytics: power targets, stamina tracking, strength/weakness analysis, and adaptive coaching
• Seamless integration with Strava, Komoot, and TrainingPeaks® via Garmin Connect™
• Large, high-resolution display for easy data reading in all light conditions

What It's NOT Good For

• Riders who don't regularly ride long enough to benefit from solar charging — the Edge 1040 Unit Only offers the same features at a lower price
• Casual cyclists who don't need advanced training metrics or long battery life — the Edge 540 or Edge 840 may be more appropriate
• Riders without a power meter or heart rate monitor who want the full adaptive coaching suite — compatible sensors are required
• Indoor-only use where solar charging provides no benefit

Frequently Asked Questions

How does the Power Glass™ solar charging work?
The Edge 1040 Solar features a Power Glass™ solar charging lens integrated into the display. In direct sunlight, it continuously harvests solar energy, adding up to 20 minutes of runtime per hour in standard GPS mode and up to 42 minutes per hour in battery saver mode. This extends total battery life to up to 100 hours in battery saver mode — ideal for multi-day tours and ultra-endurance events.

What is the difference between the Edge 1040 Solar and the Edge 1040 Unit Only?
The Edge 1040 Unit Only offers up to 35 hours of GPS battery life and 70 hours in battery saver mode. The Solar variant adds Power Glass™ solar charging, extending this to up to 100 hours in battery saver mode. All other features are identical. The Solar is worth the premium if you regularly ride 6+ hours or tour/bikepack where charging is inconvenient.

Does solar charging work in cloudy conditions?
Solar charging is most effective in direct sunlight (75,000 lux). In overcast or low-light conditions, the solar contribution is reduced. The device will still function normally on its internal battery, which provides up to 35 hours in GPS mode without any solar input.

What sensors do I need for the full training analytics suite?
For power targets, stamina tracking, and adaptive coaching, you'll need a compatible power meter and heart rate monitor. The Edge 1040 Solar supports ANT+ and Bluetooth sensors from a wide range of manufacturers. Browse our power meters and heart rate monitors for compatible options.
