OpenELAB Monocrystalline Solar Panel 18V 30-100W with Aluminum Frame
Choose the Solar Panel for Your Off-Grid Project
Build a small solar charging system around a rigid monocrystalline silicon panel, available in 30W, 60W, 80W and 100W versions. All four options are listed as 18V panels. Pair your selected panel with a suitable solar charge controller and battery for projects such as low-power lighting, remote monitoring or DIY solar-energy learning.
This is a solar panel, not a complete power station. It generates variable DC electricity in sunlight; it does not store energy or provide regulated USB or household AC power by itself.
Available Power Options
| Option | SKU | Selection guidance |
|---|---|---|
| 18V / 30W | TB-Mono-18V-30W | Lower-power experiments and modest charging needs. |
| 18V / 60W | TB-Mono-18V-60W | More rated generating capacity than the 30W option. |
| 18V / 80W | TB-Mono-18V-80W | Additional capacity where daily energy demand is higher. |
| 18V / 100W | TB-Mono-18V-100W | The highest rated power available in this listing. |
These are separate panel choices, not a four-panel bundle. Select by your daily energy requirement, available mounting space and controller limits. Rated wattage is not a guarantee of continuous output.
Panel Construction
- Monocrystalline silicon cells: convert sunlight into DC electricity for a suitably designed charging system.
- Anodized aluminum frame: provides a rigid perimeter for handling and mounting.
- Low-iron tempered glass: protects the cell surface while allowing light through.
- Layered construction: the listed EVA encapsulation and TPT backsheet help protect the cells within the module.
- Rear junction box and output leads: provide the panel's electrical connection. Confirm the lead termination before choosing adapters; MC4 connectors are not established as standard package contents.
Compatibility and What to Check
An 18V panel can be used in an appropriately designed nominal 12V battery-charging system through a compatible solar charge controller. The panel voltage is not a regulated 12V output. The controller must support the battery chemistry and charging profile, the panel's voltage and current, and any planned array configuration.
Check the actual panel label for open-circuit voltage (Voc) and short-circuit current (Isc) before final controller selection. Leave the margin required by the controller manufacturer, including for higher open-circuit voltage in cold conditions. A controller's MPPT startup voltage also matters; matching only the advertised wattage is insufficient.
Mounting dimensions need confirmation: supplier revisions list different panel sizes, including two 60W formats. Confirm the dimensions, thickness, weight and mounting arrangement of the supplied version before designing a fixed bracket or enclosure.
Getting Useful Energy from the Panel
Place the panel in unobstructed sunlight and avoid shade from trees, roof edges and nearby equipment. Clouds, dirt, panel temperature, orientation and system losses affect the energy available. Allow ventilation around the installed panel and use mounting hardware appropriate for the location.
Estimate your load in watt-hours per day rather than comparing panel watts alone. Battery storage is needed for operation after sunset. For household AC appliances, an appropriately specified inverter and battery system are also required.
Package Contents and Installation Requirements
- 1 x monocrystalline solar panel in the selected power version.
A battery, charge controller, inverter, mounting brackets, extension cables and connector adapters are not listed as included. Select correctly rated wiring and protection for the finished system. Do not connect the panel directly to a phone, an unregulated battery-charging input or household mains.
Frequently Asked Questions
Why is an 18V panel used with a 12V battery?
A nominal 12V battery needs a controlled charging voltage above its nominal voltage. A suitable controller manages the panel output to match the battery. The 18V listing does not mean the panel maintains a fixed voltage in every condition.
Can one of these panels charge a 24V battery?
Not with a conventional step-down solar charge controller from a single 18V panel. A 24V system needs a suitable higher-voltage array or a specifically compatible boost-type charging solution. The broader supplier listing's 24V wording does not make these four variants direct 24V chargers.
Will a 100W panel continuously deliver 100W?
No. Output varies with sunlight, temperature, shading and the connected system. Daily energy yield also depends on location and season, so size the battery and panel with an allowance for less favorable conditions.
Can I connect it to a portable power station?
Only if the station's solar input accepts the panel's operating range, maximum open-circuit voltage and current. Check connector type and polarity too. Similar plugs or a matching power rating do not establish compatibility.
Are the panel and connectors waterproof?
The supplier describes an IP67 junction box, which is a component rating, not a rating for every cable connection or the completed installation. Protect exposed connections and do not submerge the panel. Confirm installation-specific protection requirements before outdoor use.
