1. Has electronic equipment or output interface been connected well?

    Plug it again .

2.Does solar panel face the sunlight in the correct direction?

    After the position of the sun is confirmed, please readjust the direction.

    Do not place it in the shadow of trees, telegraph poles and other obstacles.

3.Is the surface ofthe the solar panel contaminated with dirt?

    lf the surface becomes dirty, wipe it with a soft wet cloth.

    Never use thinner or benzine .

4. Confirm the environment or weather.

    The generating capa city is low in cloudy weather.

Q: Why it cannot be used to charge electronic equipment?

Q: Can the solar panel generate power in cloudy weather?

Yes, it can, even though it generates much less power than in sunny weather.

Q: What is the difference between nominal output an d actualoutput of solar panel?

The nominal maximum output power (rated output) of solar battery is avalue calculated according to standard state.“Standard state" means thatsurface temperature of solar battery module is 25C and sunlight intensityis 1000 w/㎡

Generally actual output is lower than the nominal maximumoutput power due to thefollowing reasons:

1) Installation environment or weather

2 Characteristics of solar battery.

3 Dirt on the panel surfa ce.

)The generating capacity decreases due to energy loss

5) When only a part of the solar panels are exposed to sunlight, the powergeneration efficiency decreases and the power output becomes weak.Please fully expand the solar panel and do not shade it from the sun.

In fact, the output power is only 70-90 % of the rated power when thesolar power system runs even in sunny weather.
