Lovely, modern-looking panels. A very good impression from the panels thus far. The panels themselves show about 5% production-related variation, but I guess this is normal

We paid close attention to the panel's appearance. They've got that sleek, contemporary all-black look. We recommend both Phono panels and A1Solar store

Instead of spending a fortune on LG NeON panels, you can get comparable performance from these Phono solar panels... Perform as intended...

what is the shipping cost to 92407
A1 SolarStore
Shipping starts at $250 for up to 8 solar panels, and goes up by $25 with every 4 modules on top of that. Some panels qualify for free shipping when ordering over 10 items.

I am putting these on a pool pump that needs 1200w. How can I link them together? Do you have brackets?
A1 SolarStore
You can either connect the panels in parallel or in series. We do not sell brackets separately, but we include them in our solar kits. If you need a turnkey solution, please press "Systems" at the very top of this page.

if i am charging a 12v parallel bank, will a proper mppt controller efficiently use the 30+v output of these panels or simply throttle it?
A1 SolarStore
A proper MPPT controller will efficiently use the output of these panels.

FAQ

How much is shipping and how long is delivery?
Our standard shipping charge is $250 for up to 11 panels and it is increased by $25 for every 4 additional panels. In the event, the product is only available on East or West coast custom quote will be sent to you before the order is processed. Normally, we are able to deliver solar panels within 7 business days.
What is the difference between low price panels and top price panels?
With top tier solar panels, you pay for the brand name, proprietary new technology, higher energy output, and better warranty support.
What are the dimensions of the panel?
Please refer to the product datasheet on the product page. We have a datasheet for every product we sell.
How long is the warranty on the panel?
In general, manufacturers provide a 25 year-long performance warranty and a 10 year-long equipment guarantee. Some manufacturers offer 12-15 years of warranty. More information is available in our warranty support section.
Which panels do you recommend for RV, marine?
We recommend Panasonic and Mission Solar panels for smaller systems as their high energy output and excellent craftsmanship guarantee years of service.
Can this panel be used with a 12v system?
Any of our panels can be used for a 12v system with a properly selected inverter and charge controller.
Can I pick up this panel from your fulfillment center to save on shipping?
Yes, we can set up a pick up at a local distributor. Please call to discuss options and stock availability.
How do I connect these panels?
To achieve the best system efficiency, panels should be connected in series to create higher voltage.
How many panels do I need?
This number is determined by your average energy needs. Depending on the type of panels and energy consumption, you might need anywhere from 12 to 45 solar panels. Remember, the more panels you install the more energy you will get.Please use our solar calculator to estimate your energy consumption and plan on building a solar system that will exceed your energy needs by 25%.
How do I build a solar system?
Please use our solar calculator to estimate what equipment you need. Choose your panels, microinverters, inverters, and solar batteries if necessary.Please note that we do not offer solar system design or installation.
How do solar panels compare?
Solar panels differ by power output, voltage, connection type, size, efficiency, and weight. Some solar panels might be sold together with microinverters as a set.
Can I build a solar system by myself as a Do It Yourself project?
Yes, it is possible if you understand what solar equipment you need and how to connect it together. However, please be mindful that handling your own electrical work without having proper experience might cause life-threatening injuries. Please contact a certified electrician if you do not possess appropriate electrical skills.
Can I connect and charge my solar panel battery directly with the solar panel?
We do not recommend using the solar panel without the charge controller. Using solar panels without the charge controller might damage the batteries.
Can I drill holes into the aluminum frame for mounting?
We do not recommend drilling any new holes to the aluminum frame of the panel as it could damage the internal circuit and solar cells. (Also, any modification to the panel will void the warranty). We recommend only using the pre-drilled holes for mounting.
Do solar panels require maintenance? Can I wash my solar panel?
Solar panels generally require very little maintenance. We recommend cleaning the solar panel with water, glass cleaner (Windex) and microfiber cloth.
Will my panel produce power in an overcast condition?
While solar panels require sunlight to generate solar energy, they will still work in cloudy weather. Even on a cloudy day, solar panels will produce energy just not as much.
Will my panels produce power if covered with snow?
Solar panels cannot produce electricity if covered with snow.
What is the best direction for a solar panel to face?
The best direction for a solar panel to face is the South

About product

PS-20-UHB is part of the Twinplus Series — one of the most recent made by Phono Solar. These panels employ cutting-edge technologies to achieve superior efficiency and reliability. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight. 

To further boost the performance, Phono Solar employs half-cut cell technology. Each of the panel’s 120 cells is only half the size of a traditional solar cell. This grants PS-20-UHB lower resistive losses and better shade tolerance. At 20.31% efficiency, PS-20-UHB offers surprising performance for its weight and size. Cell surface, back foil and frame are completely black, giving the model unrivaled aesthetics. Phono Solar offers 12 years of product warranty and guarantees 84.8% of original performance after 25 years of operation. 

  • 370 W power output
  • 120 half-cut PERC cells
  • 20.31% efficiency
  • 1500 V DC maximum system voltage
  • MC4 connectors
  • 12-year product and 25-year performance warranties


More energy and efficiency

The PERC technology further improves an already excellent efficiency of 20.31 percent. A reliable PID resistance and a unique glass lamination were added by the maker, which ultimately produced a model that was effective and extremely durable. PS-20-UHB produces 370 W of power under typical test settings.

Heat-resistant performance

The heat is less of a threat with this module: with one of the lowest temperature coefficients in the industry, PS-20-UHB loses just 0.36% of efficiency for every 1.8°F above 77°F.

High quality standards

Phono Solar strict manufacturing standards include multiple tests to provide extreme quality assurance. The facilities are highly automated, allowing the company to maintain high standards and keep the level of warranty claims very low.


Low degradation for increased lifespan

The amount of power output loss experienced by these panels during the first year of operation will not exceed 2%. The average yearly power drop from the second to the 25th year will not surpass 0.55%. After 25 years, the module will still produce more than 84.8% of its initial output.

A panel that can handle hail, wind and snow

The 1.18" frame built of anodized aluminum and a layer of protective tempered glass make this module weather-resistant. The front side of the modules can withstand a 5400 Pa load, whereas the back side can withstand a 2400 Pa load.

Outstanding all-black design

The panel features all-black design which looks great on any roof. The manufacturer ensures excellent cell color by special treatment and selection processes. Phono Solar engineers use thinner wires to connect the cells together, and at a distance the surface of the modules appears smooth and uninterrupted.
