plz tell if they work in shade decent
A1 SolarStore
Half-cut cells minimize shade losses better than full cells. Still, full sun's best.

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

FEOC-Compliant Solar Panels

These solar panels are compliant with FEOC standards and contain 43% Domestic Content. Compliance confirmation available upon request.

156HC M10 NTYP SL 640W is a model that uses a number of technologies to bring durability and performance to the next level. This panel has solar cells half the size of those found in standard panels. Major advantages include reduced power consumption, extended life, and enhanced efficiency in low-light conditions.

Not surprisingly, the efficiency of this module is quite high – 22.90%. And while conventional panels absorb photons only on one side, bifacial modules absorb photons on both sides simultaneously. Thanks to the technology, this model can be up to 30% more efficient. Heliene offers a 15-year product warranty and guarantees 89.40% of the original performance after 25 years of operation.

  • 640 W power output
  • 156 half-cut TOPCon cells
  • 22.90% efficiency
  • 1500 V DC maximum system voltage
  • Multi-Contact/ Stäubli MC4 connectors
  • 15-year product warranty and 25-year linear performance guarantee

Great productivity through the latest innovations

This Heliene panel provides 640 W power at 22.90% efficiency. High energy production levels are achieved through the usage of the latest advances in the solar industry, including TOPCon technology and state-of-the-art antireflective coating. An efficient panel yields more per square foot and pays for itself faster.

Keeping cool in high temperatures

Even under extreme heat, 156HC M10 NTYP SL 640W maintains high efficiency. You may take advantage of the sunniest hours because it loses just -0.3% of efficiency for every 1.8°F over 77°F.

High-quality standards

Heliene's 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 a longer lifespan

These panels will lose no more than 1% of their power output in the first year of service. From the 2nd year to the 25th year, the average annual power decline will be no more than 0.4%. The module retains over 89.40% of its original output after 25 years. Guaranteed by Heliene.

A panel that can handle hail, wind, and snow

The 1.38" frame, built of anodized aluminum alloy 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.
