It was a pleasure working with you on the installation of our home solar system. As homeowners doing the project ourselves, it was extremely helpful to have you on the other end of the phone line providing us with guidance and information needed to enable us to have a successful installation. We so appreciated your follow up, attention to detail and ability to answer our technical questions.

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

LONGi 440w Mono PERC w 144 Half-cut Cells (72 cell equivalent). Silver 35mm frame, white backsheet and MC4 connectors w/ 1400mm cable.

LONGi 440W solar panels are among the most powerful PV modules on the market. The LONGi HPH Series combines High Efficiency, Low LID Mono PERC cells with Half-cut Multi Busbar Technology to improve performance and boost production. This module series has a max system voltage of 1500V and is Fire Rated as Class C (per UL790). 35mm frames reduce weight while still providing the strength and resilience needed to rate 5400Pa for front side static loading and 2400Pa for rear side static loading. In spite of the high power output of this model, 440W solar panel price is quite low.

Higher Efficiency

High conversion efficiency up to 18.8%. Excellent performance in low irradiance conditions, such as dawn, dusk and cloudy days. Check LONGi 440W datasheet for more technical details.

Quality and Reliability

High-quality assurance due to stringent quality control. Solid PID resistance ensured by solar cell process optimization and careful module BOM selection.

Slower Power Degradation

Slow power degradation enabled by Low LID Mono PERC technology: first year - 2%, and then - 0.55% every year.

LONGi Solar 440w performs well in high-temperatures due to anti-PID technologies used in processing solar cells and encapsulating modules. Panels are good for installation in hot and highly humid areas.

Excellent anti salt mist and anti-ammonia capability and harsh environment adaptability. Super robust resistance and able to bear 2400 Pa wind load and 5400 Pa snow load. Check LONGi Solar 440W datasheet for more information on the properties of the model.

Performance Warranty

LONGi 440W panels come with strong warranties. This model provides a 10-year product warranty for materials and processing and 25 year warranty for extra linear power output.
