Note:

• Take note of factors that can affect the solar panel’s output performance like load impedance, sunlight intensity, temperature, clouds or shadow.
• Since, the output power of solar panels depends on temperature, solar irradiance, and other factors, therefore, the efficiency of solar panels need to be under standard conditions such as air quality (AM1.5) and light intensity (1000W/m2).

Product Description

Developed for long-term mechanical stability, made from highly purified polysilicon. Includes 2 bus bars to minimize series resistance, while enhancing solar module and cell efficiency.

The texture design offers a stable appearance and virtually transparent crystal structure, while the blue anti-reflection coating further improves the light absorption in low light instances. The panels good low light behavior improves energy yield.

The DIY solar kit is best used under the sun’s peak from morning around 7 am to afternoon around 4 pm.

It can arbitrarily change the output power and voltage in different connection such as in parallel or series to meet your needs.

The blue side connects to the “-” (negative), while the white side connects to the “+”(positive). In order to have enough power, its suggested to use soldering and copper strips for connection.

The solar panels have bright surface and excellent transmission. Its lightweight, thin, with shape appropriate for commonly used in most DIY solar products. With high conversion rate and high-efficiency output, handle the cells carefully, since the micro-thin design can be damaged, if held or carried roughly. Handle it with care so it last longer.

The application includes solar power system, solar lawn light, and garden light. Mostly, its used for ‘do-it-yourself’ projects for traditional framed solar panels, solar phone charger, and solar backpack charger.
