Phono Solar 400W Solar Panel: The Gold Standard
The Phono Solar 400W solar panel is the perfect mix of efficiency and value, which is why it’s the best-selling panel we stock. With a 19.9% efficiency rating, these panels allow you to produce more power with a smaller array.
That makes the Phono Solar 400W panel ideal for large-scale commercial projects, as well as residential rooftops with enough room to accommodate a taller panel design. They also work well for ground-mount arrays, where there’s plenty of space to build your system.
Cutting-Edge Cell Tech
Phono Solar’s 400W panel uses half-cut cells, which are more resistant to physical damage, and more shade tolerant than panels with full-sized solar cells.
They also make use of PERC (Passivated Emitter and Rear Cell) technology. PERC cells add a layer of material to the back of the cell, to capture more light and improve efficiency.
Thanks to advancements in cell technology, Phono Solar’s 400W module is more efficient and more reliable than its traditional 60-cell or 72-cell counterparts.
Lower System Costs
Building a system with large, efficient panels means you’ll need to buy fewer panels to meet your energy needs. For example, you’d need thirteen 310-watt panels to build a 4kW solar array - or you could reach the same power output with just ten of these 400-watt panels.
With fewer panels to install, you’ll save money on other system components, like wiring, racking materials, and micro-inverters / power optimizers that would be paired with each panel. That can add up to hundreds (even thousands) of dollars saved on your solar project.
Withstand the Elements
The Phono Solar 400W module is a heavy-duty panel that is built to brave the elements. With a 5400 Pa snow load capacity, these panels belong on snow-covered rooftops from the Rockies to the Great Lakes. (Of course, they’ll work just fine in sunny Southern California too.)
Certified Tier 1 Solar Panels
Phono Solar is recognized by Bloomberg New Energy Finance as a Tier 1 Solar Manufacturer, a designation reserved for manufacturers with a reputation of quality and longevity in the solar industry.
A Tier 1 designation signals high sales volume, a stable balance sheet, an automated production line with strong quality control checks, and a healthy reputation in the industry. See Bloomberg’s full criteria to make the cut (PDF).
Phono Solar backs their 400W solar panel with a 12-year product warranty and 25-year performance warranty, so you can rest easy knowing your investment is protected for the long term.
