Small size solar panels are also called customized solar panels which means they are higly customizable, you decide how the solar panels will be as following:
1: Types of solar cells: mono or poly;
2: Number of cells: 1/2 cutted, 1/3 cutted, 1/4 cutted;
3: TPT backsheet: white, black or other;
4: EVA film: white or color;
5: Frame: the length, the width, the thickness, the color;
6: Juction box: IP level(65-68), brand;
7: Cable: the length(null-1meter), the width;
8: Connectors: MC4, anderson, clips;

The light image above is our 30w solar street light project in Nigeria. Solar street light is highly appropriate for the area that has an immature utility facility or has rich solar energy resources. Solar street light as a safe, environment-friendly, and convenient project is becoming more and more popular and gets more attention nowadays. The project concludes three main parts, 30w solar panel, 6 meters stainless embedded rod with brackets, and LED lightbox with 25ah battery. Each street light consumes 300w daily that generated by the small size 30w solar panel. The solar street light has good water and thunder resistance therefore make it durable in usage.
Benefits:
1: small size solar panels are also called customized solar panels which means the dimensions, the color, the cell’s size, the voltage and almost everything are customizable.
2: when speaking of size and voltage, small size solar panels are more suitable and convenient for residential off-grid solar power system, for example, 5-10v solar light system for garden.
3: Because of the small size, the maintenance (when there is snow or dirt) as well as the installation work of small solar panels are much more easier than large panels.
