six months in and no issues. they work every day and produce good power. installation was straightforward with standard racking
One thing I didnt expect is how well these perform in cold weather. Even when its freezing they still put out good power. The snow slides off pretty easy too
bought these for my farm and theyre doing exactly what i needed. cant complain about the price for panels with 30 year warranty
Been using these for my home system since March. They work as advertised. Not much else to say - they sit on my roof and make electricity. The efficiency rating seems accurate based on my monitoring system.
installed these panels and they've been running for 3 months now. power production is actually higher than the rated on sunny days. very happy with this purchase
Installed on pole mount for RV park. Reliable power all summer even partial shade. Long warranty sold me
Solid performer. Had em up 2 months output steady. Bifacial gain bout 15% on my setup.

whats the power degradation after 25 years
A1 SolarStore
After 25 years, these panels are guaranteed to produce at least 87.55% of their original power (2% first year + 0.45% × 24 years).

How do I calculate how many panels I need
A1 SolarStore
Divide your daily energy consumption (kWh) by your location's peak sun hours, then divide by the panel wattage (0.56 kW). Add 25% for system losses.

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

CHSM72M(DG)/F-BH-555 is a model that uses a number of technologies to bring durability and performance to the next level. This panel takes full advantage of the Passivated Emitter Rear Contact (PERC) technology that allows it to capture up to 12% more energy. All thanks to a reflective layer on the back. This design maximizes the number of photons absorbed by solar cells.

The use of half-cut cell technology is an additional perk. The solar cells of CHSM72M(DG)/F-BH-555 are half the size of those found in standard panels. Major advantages include reduced power consumption, extended life, and enhanced efficiency in low-light conditions. At 21.5% efficiency, CHSM72M(DG)/F-BH-555 offers surprising performance for its weight and size. And while conventional panels use only one side to absorb photons, bifacial modules employ both sides at the same time. Thanks to the technology, this model can be up to 30% more efficient. Astronergy provides 15 years of product warranty and guarantees that after 30 years, performance will be at 84.95% or more.

  • 555 W power output
  • 144 half-cut PERC cells
  • 21.5% efficiency
  • 1500 V DC maximum system voltage
  • HCB40 (Standard) / MC4-EVO2A (Optional) connectors
  • 15-year product warranty and 30-year linear power warranty

High efficiency of 21.5 percent

Astronergy ASTRO 5 Twins Bifacial panels fully use the firm's innovations, for which Astronergy has received several distinctions. With PERC technology, more electricity can be produced per square foot of PV modules. As a result, fewer clamps and racks will be required during installation. All of which lowers your overall expenses and accelerates the payback period.

High-quality standards

Astronergy's stringent production requirements include various tests to guarantee high quality. The facilities are highly automated, allowing the manufacturer to maintain high standards while keeping warranty claims to a minimum.

Reliability and degradation resistance

Astronergy guarantees slow degradation over the next 30 years. The performance will decrease no more than 2% during the first year and 0.45% annually thereafter. Your modules will retain at least 84.95% of their original performance after 30 years. This 555 W Astronergy solar panel also comes with a generous 15-year product warranty.

A panel that can handle hail, wind, and snow

This module is weatherproof due to the 1.38" frame manufactured from anodized aluminum alloy and a layer of safety tempered glass. The modules' front and rear sides can withstand loads of 5400 and 2400 Pa, respectively.
