If you are installing a Lockin external solar panel, aim the panel’s solar-facing surface toward the part of the doorway that receives direct sunlight around midday. The panel should not be aimed at the lock body just because it is mounted beside the lock; it needs a clear view of usable daylight.
For a Lockin Veno-series setup, place the panel where the doorway, trim, porch roof, storm door, railing, or nearby wall will not cast a shadow over it during the strongest part of the day. Then connect the panel to the exterior assembly through the Type-C port and verify charging in the Lockin Smart App under Device → Setting.
The short answer: aim for direct midday sun
Lockin’s FAQ recommends installing the compatible solar panel when the sun is directly shining on the lock during midday. That is the most useful placement rule for this question. Stand outside the door and look for the mounting position where the panel receives the clearest direct light near midday—not necessarily the position that is closest to the lock or easiest to hide.
Do not choose a compass direction from a generic rule such as “always face south.” The best direction depends on the doorway, nearby obstructions, season, and the actual path of the sun at your home. Use the light that reaches your specific entryway as the deciding test.
Check these conditions before you mount the panel
1. Confirm the exact lock and panel combination
Lockin’s current standalone Veno Series Solar Panel product page lists compatibility with Veno Pro and Veno Plus. The storefront also displays a Veno + Solar Panel option in some product navigation. Treat the exact model-and-option combination in your cart, product page, and manual as the authority; do not assume that a panel that looks similar is compatible with every Veno model.
If the product page and your selected option disagree, pause installation and ask Lockin support to confirm the combination for your exact lock.
2. Look for midday shadows, not just morning light
A location can look bright when you install it and still be shaded when the sun is highest. Check the panel’s proposed position around midday and note whether any of these block direct light:
- A porch ceiling or deep overhang
- A storm door or screen-door frame
- Door trim, a neighboring wall, or a railing
- Trees, balcony edges, or seasonal foliage
- A camera, light fixture, sign, or other accessory
If a short shadow crosses the panel, test another nearby position with a clearer view. Keep the cable path and the panel’s mounting instructions in mind while comparing locations.
3. Keep the installation area compatible with the lock
For the Veno series, Lockin’s FAQ lists a minimum distance of 3 inches (75 mm) between the handle and the crossbore center for solar-charge-panel installation. A panel can have good sunlight and still be a poor installation if it interferes with the handle, door swing, weather sealing, or cable routing.
Check the exact model’s current product page and manual for door type, dimensions, clearance, and mounting instructions before drilling or fixing the panel. The solar panel does not replace the lock’s door-fit requirements.
A practical placement test
Use this quick test before permanently fixing the panel:
- Hold the panel in the proposed position with the solar-facing surface pointed toward the brightest direct light available around midday.
- Confirm that the panel is not behind a porch roof, storm door, trim, or another obstruction.
- Check that the cable can reach the exterior assembly without being pinched when the door opens or closes.
- Connect the panel to the exterior assembly through the Type-C port.
- Keep the lock battery installed. Lockin advises not removing the battery during solar charging.
- Open the Lockin Smart App and check Device → Setting for the battery and charging status.
If the app does not show charging, first recheck the Type-C connection and the amount of direct light at the panel. Then confirm that the lock is connected to the app and that the Wi-Fi connection is stable, as Lockin includes those checks in its solar-charging guidance.
What if the panel cannot get direct midday sun?
Do not promise yourself a fixed charging result from a shaded location. Lockin’s general solar guidance for the external Veno-series panel points to direct midday sunlight, so a permanently shaded position should be treated as a placement risk. Move the panel to a clearer location if the cable and model-specific mounting instructions allow it.
If you cannot create a suitable placement, keep the lock’s normal charging and emergency-entry plan ready. Lockin’s FAQ describes Type-C emergency power and a mechanical key for a depleted Veno-series battery. Solar assistance should reduce charging work; it should not be treated as the only way to regain entry.
Also note that an external-panel Veno setup is different from Lockin’s Veno Solar models, which use an integrated solar design. Choose and troubleshoot by the exact model name rather than applying one model’s solar instructions to another.
Final checklist
The right answer to “where should you aim an external solar panel for a Lockin smart lock?” is: aim the panel’s solar-facing surface toward the clearest direct midday light at your actual doorway, while preserving the required clearance and cable path.
Before finishing, verify:
- The panel is listed for your exact Lockin model or selected option.
- Direct midday light reaches the panel without a recurring shadow.
- The panel does not obstruct the handle, door movement, or weather protection.
- The cable is connected to the exterior assembly through Type-C.
- The battery remains installed during the charging check.
- The Lockin Smart App shows the expected battery or charging status.
- You still know the mechanical-key and emergency-power procedure.
