Frequently Asked QuestionsWhat is the difference between off-grid and on-grid solar systems?
An off-grid solar system works independently from the utility grid and usually requires batteries, a solar charge controller, and other components to store and supply power.
An on-grid solar system connects to the utility grid through a grid-tie inverter. Excess solar energy may be sent back to the grid, while the grid can also be used as backup power.
Why is the actual output lower than 100W sometimes?
The rated 100W output is measured under Standard Test Conditions / STC. In real outdoor use, solar panel output may vary due to:
- Sunlight intensity
- Temperature
- Installation angle
- Shading
- Dust or dirt on the panel
- Cable and controller losses
This is normal for all photovoltaic solar panels.
Should I connect solar panels in series or parallel?
Series connection increases voltage and is useful for longer cable runs or systems that require higher input voltage.
Parallel connection increases current while keeping voltage the same, and it may offer better performance when partial shading occurs.
Always make sure the final voltage and current are within the limits of your inverter or charge controller.
Why is this called a 12V solar panel if the working voltage is around 18V?
“12V” refers to the nominal battery system voltage. A 12V solar panel typically has a maximum power voltage / Vmp around 18V, which provides enough voltage to charge a 12V battery through a PWM or MPPT charge controller.
Is this panel compatible with MPPT and PWM charge controllers?
Yes. This solar panel is compatible with both PWM and MPPT charge controllers.
For better charging efficiency, especially in changing sunlight conditions, an MPPT controller is recommended.
What is the best installation angle and direction?
For best energy production:
- In the Northern Hemisphere, face the panel toward true south
- In the Southern Hemisphere, face the panel toward true north
- Tilt angle should be close to your local latitude
Seasonal angle adjustment can help improve overall energy yield.
What maintenance is required?
Basic maintenance includes:
- Cleaning dust, dirt, leaves, or snow from the panel surface
- Checking cable and connector conditions
- Inspecting mounting hardware regularly
- Keeping the panel away from shading
Proper maintenance helps maintain stable power output and extend service life.
Package Includes
- 1 × 100W N-Type Solar Panel
Mounting brackets, charge controller, cables, and batteries are not included unless stated otherwise.
Important Notes
- This solar panel is designed for off-grid solar applications.
- A solar charge controller is required when charging batteries.
- Please confirm your system voltage, controller input limit, and wiring configuration before installation.
- Actual output depends on sunlight conditions and installation environment.
