If you're going solar with LA Solar Factory panels, your installer will install panels from one of the lines below as part of your system – all of them are monocrystalline modules (meaning they're highly efficient).

The company is the world’s best 390w Solar Panels Factory supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.

LS430BL - LS550BL

This series comes in wattages from 430 Watts (W) to 550W, increasing in increments of five Watts from 430W - 450W and 530W - 550W. The panels in this series range in efficiency from 19.7% to 21.8% – relatively high due to their half-cut solar cell technology, which increases the panels' efficiency by reducing heat loss. This type of solar cell structure can be more expensive to produce but also speeds up the installation process, as you'll need fewer panels to meet your electricity needs due to their increased efficiency.

LS390HC - LS450HC

This series is offered in wattages ranging from 390W to 450W, increasing by increments of five Watts (although they skip 425W). The panels range in efficiency from 19.61% to 20.93% and have the same solar cell technology as the BL line.

LS340ST - LS400ST

This series is offered in wattages ranging from 340W to 400W, increasing in increments of five Watts. The efficiency of these panels ranges from 17.52% to 20.19%, and LA Solar Factory notes that the lower wattages (ranging from 340W to 370W) are best suited for temperate climates or higher-temperature areas.

LS530BF - LS550BF

This series includes LA Solar Factory's highest wattage panels ranging from 530W to 550W. These panels range in efficiency from 20.56% to 21.28%. Although they are very efficient, it's unlikely that your installation company would include these panels as part of a home solar system, as their wattages are higher than the typical 500W cap across the solar industry for home solar projects. Generally, they're better suited to small-scale commercial and industrial installations.

We'll dive into these series' efficiency ratings, performance, and warranties below.

OEM 390w full black shingled solar cells

Advantages of shingled solar cells:

1、 Solve the hot spot problem, and enhance the crack resistance. Due to the unique arrangement of the laminated modules, the influence of the resistance of the welding strip on the power of the module is reduced, the minimum power loss during the module packaging process is guaranteed, and the influence of the reverse current on the hot spot effect of the module is reduced. The unique flexible connection of the laminated tile module can effectively reduce the hidden crack of the battery chip that may be caused by the module transportation and on-site installation, and control the hidden crack extension.

2、 It is applicable to high sheltered areas such as high latitude and intensive land use. Compared with other conventional components, the laminated component has lower power loss under partial shading, so it is more suitable for high latitude areas, land intensive projects and distributed projects.

3、 Increase the number of battery cells to increase the power of components. The number of dischargeable battery chips increases by 13%, and the power of the module can be increased by 15-20W. The lamination technology realizes no battery chip spacing by overlapping small battery chips. More battery chips can be placed in the same area, which effectively expands the light receiving area of the battery chip. The power generation gain can reach 18.5%, and the module efficiency can be improved to 18.81%, which is much higher than the half chip, multi grid and other component technologies: high density, space saving, The number of battery chips that can be placed on the same type of components increases by 13%.

4、 The design without main grid is adopted to reduce the shading area of metal grid line. The non main grid design of the laminated battery reduces the shading area of the metal grid line and improves the output power of the module.

 

5、 Serial parallel structure reduces internal resistance and shading effect. The special series parallel structure of the laminated module reduces the internal resistance and internal power consumption of the module. The parallel circuit design makes the power drop of the laminated modules have a linear relationship with the shadow shielding area. Compared with other conventional modules, it performs better under the condition of partial shading.
