JA Solar
Founded in 2005, the Shanghai based JA Solar has become a major exporter of solar panels and related solar PV systems equipment over the past two decades.
The company is a major manufacturer of monocrystalline solar panels through its flagship Deep Blue 3.0 and 4.0 series.
Today the company delivers products to 165 countries and regions, with more than 50,000 employees in its different branches.
Since its foundation, JA Solar has produced approximately 201GW worth of solar PV modules for use around the world.
Along with residential solar panels, JA Solar also produces solutions for large scale solar farms, agri-voltaics, and floating solar power plants.
High Performance Solar Panels
JA Solar’s Deep Blue 3.0 solar panels combine half-cut solar cells with PERC technology for a high performance and efficiency at any affordable price.
The use of Mono half-cut solar cells in the Deep Blue 3.0 Solar Modules guarantees a high power output regardless of whether part of the solar panels is shaded, with the layout of the half-cut cells which make up the module minimising power loss compared with older designs.
PERC technology also helps to improve the power output of the solar panels by reducing loss from electron recombination.
These combine to give JA Solar’s Deep Blue 3.0 JAM54S31 modules an efficiency of 22%, while also being considerably more affordable than the highest efficiency modules on the market.
Multi-Busbar Solar Cells
Multi-Busbar cell technology employed in the Deep Blue 3.0 solar panels reduces series resistance by decreasing the current flowing through the fingers and the busbars.Â
It also helps to make solar panels more durable as the soldering of the ribbons between the busbars is more flexible, reducing the risk of microfractures.
Finally, MBB solar panel design uses less silver paste for the connections, making the panels more affordable by cutting down on one of the major costs.
25 Year Performance Guarantee
The Deep Blue 3.0 440W solar panel guarantees a minimum performance of at least 84.8% of its original output after 25 years of service.
The panels should expect no more than a 2% loss of power output within its first year of service, and an expected 0.55% annual degradation each year thereafter.
This means that if after 25 years the panels are delivering less than 84.8% of their original power output, they are within the warranty for replacement.
12 Year Product Warranty
Many things can happen over the course of more than a decade, and the 12 year warranty for JA Deep Blue 3.0 solar panels provides peace of mind for homeowners in the event that they are damaged by weather or other circumstances.
Sleek Aesthetics
The all-black design of the Deep Blue 3.0 JAM54S31 solar panels creates an elegant appearance that blends in with the majority of rooftops, ensuring that it doesn’t negatively affect the amenity of a property.
Coming in at just 20kg per module, and dimensions of 1762mm x 1134mm x 30mm, the Deep Blue 3.0 panels are compact and easy to handle despite their impressive power output.
