With top tier solar panels, you pay for the brand name, proprietary new technology, higher energy output, and better warranty support.
Please refer to the product datasheet on the product page. We have a datasheet for every product we sell.
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.
We recommend Panasonic and Mission Solar panels for smaller systems as their high energy output and excellent craftsmanship guarantee years of service.
Any of our panels can be used for a 12v system with a properly selected inverter and charge controller.
Yes, we can set up a pick up at a local distributor. Please call to discuss options and stock availability.
To achieve the best system efficiency, panels should be connected in series to create higher voltage.
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%.
We do offer discounts for orders of over 50 units. Please contact us for details.
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.
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.
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.
We do not recommend using the solar panel without the charge controller. Using solar panels without the charge controller might damage the batteries.
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.
Solar panels generally require very little maintenance. We recommend cleaning the solar panel with water, glass cleaner (Windex) and microfiber cloth.
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.
Solar panels cannot produce electricity if covered with snow.
The best direction for a solar panel to face is the South.a
The new high-performance module Q-Cell 400W DUO L-G5.3 Solar Panel is the ideal solution for commercial and utility applications thanks to a combination of its innovative cell technology Q.ANTUM and cutting edge cell interconnection. This 1500 V IEC/UL solar module with its 6 busbar cell design ensures superior yields while having a very low LCOE. Hanwha enhanced low-light performance and the output of Q CELLS across a wide range of temperatures for Q.PEAK DUO solar panels to rival traditional crystalline technologies.
- 400W Power Output
- 19.9% Module Efficiency
- MC4 Connectors
- Extreme weather rating
- 6 busbar solar cell design
- Excellent low-light and temperature behavior
- Silver frame, silver back
19.9% Efficiency Rate
The new Q.ANTUM DUO Technology combines cutting edge advancements in cell separation technology with round wires – reducing both electrical and optical losses, respectively. It means higher yield per surface area and an efficiency rate of 19.9%.
Innovative All-Weather Technology
Q Cells guarantees high performances under real conditions, in winter or summer, under clear or cloudy skies, and for extreme weather.
Quality and Reliability
Q.ANTUM DUO not only increases nameplate power, but also improves reliability. The manufacturer provides 25 year linear performance guarantee, which certifies that Q-Cell G5.3 400w Solar Panel will produce at least 97% of the minimal rated power output in the first year and at least 83% in year 25.
Anti LID/ LeTID ensures low initial degradation of Q-Cell G5.3 400w Solar Panel, maximum 0.54% degradation per year.
Improved Cell Design
Q-Cell G5.3 400w Solar Panel consists of 6 x 24 monocrystalline Q.ANTUM solar half cells. The half-cell design minimizes cell stress reducing the potential for micro cracks in the field.
With Q CELLS high quality modules, you are covered by a 12 year product warranty and a 25 year linear performance guarantee.
