Product Overview
The SLP 20W polycrystalline solar panel supplies DC power for small solar installations. It is suited to customers planning low-power off-grid lighting, monitoring or other equipment, with the panel and control equipment selected to match the load.
Key Features
- 20W rated output under standard test conditions helps size the panel for the intended energy requirement.
- Maximum-power output of 17.50V and 1.15A provides the electrical ratings needed for controller selection.
- An anodised aluminium alloy frame supports a fixed installation.
Applications
- Small off-grid lighting installations with suitable control equipment.
- Low-power monitoring and remote DC equipment matched to the panel output.
- Battery-based solar systems using a suitably rated charge controller.
Why Choose This Product?
The SLP 20W panel provides a compact generation option for installations with modest power requirements. Its published voltage, current and dimensions make it straightforward to assess against the available mounting space and system design.
Important Notes
- Rated output is measured at standard test conditions: 1000W/m² irradiance, 25°C cell temperature and AM1.5. Actual output varies with sunlight, temperature, shading and installation.
- Use a suitable charge controller for battery charging. Have a qualified installer check voltage limits, battery requirements, cabling, protection and mounting.
