What are the possible reasons for the product without voltage and current output?
If there is no voltage and current output of the LE series products, the main reason is that the copper zone between solar cells appears disconnected in multiple places, causing no voltage and present data.
The copper band connected between the solar cells is welded with a stamping copper tape structure to enhance the firmness and stress area of the copper band.
There are bubbles for LE 180W solar panel surface materials. What is the reason?
When the 180W solar panel is installed on the yacht, during no use, due to the sunshade, a hot spot effect will occur. The solar panel’s local surface temperature increases, affecting the adhesion of the surface material and EVA. The local surface will turn white when the temperature drops and the bubbles disappear. Therefore, when using it, it is best to avoid using it on covered occasions.
What is the reason for the no voltage output when we install the lightweight board to the RV？
There will be no voltage output installed on the RV in the market. It can be determined whether the copper tape is disconnected after the product is vibrated on the top of the RV. If it is disconnected, it will be affected. The glass fiber material process we used in Sungold can prevent this problem occurs.
Is the diode of the lightweight solar panel’s junction box easy to burn out?
The diode of the junction box will burn out due to excessive external reverse current. We generally standardize the protective measures of the product during use in the product manual.
Is the junction box used in the lightweight solar panel waterproof?
We use the glue-filled junction box to install the product, so it has excellent waterproof performance and can resist the impact of the external environment.
Why can you trust Sungold solar’s solar panel products?
Sungold solar is one of the leading Chinese solar panel manufacturers. Sungold solar focuses on manufacturing solar panels and keeps innovating processes. The products use specially developed patented materials and the latest solar cell technology to achieve higher conversion efficiency.
What can a 180W solar panel run?
If you have installed just two 180 Watt solar panels at your residence, you can comfortably run your household appliances like bulbs, fans, TV, refrigerator, washing machine etc. during day time, completely independent of the power from the grid.
How much power does a 180 watt solar panel produce?
The 180 W solar panel has a universal MC4 output. Via this output, the solar panel can daily generate an average of 850 Wh of energy.
How long will a 180W solar panel take to charge a 100Ah battery?
In general, a 100Ah deep-cycle lead-acid battery would require 180 watts of solar panel to fully recharge from 50% Depth of Discharge (DOD) assuming 4.2 peak-sun-hours per day. It would take 8 hours to fully recharge with a clear sky.
How many amps should a 180W solar panel put out?
The size of your solar panel array. Example, 1x 180W solar panel in full sun at 12V will produce up to 10 amps. Charging method and efficiency of your solar regulator.
