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
310W LONGi Solar Panel is a highly efficient, low LID Mono PERC 120 cell module that represents the latest half-cut technology. It features black 40 mm frame, black backsheet, 1200mm cables, MC4 connectors, and industry-standard -0/+5W sorting.
LONGi's latest advance in module technology, the HPB series, boasts excellent low light performance and reduced PID susceptibility. Max DC System Voltage: 1000V Center Mounted J-Box.
Higher Efficiency of up to 19.3%
Great power output and greater energy yields. Outstanding power output in low light conditions, such as dawn, dusk and cloudy day, with relative average efficiency of 97.5% or better. Positive tolerance of maximal power guaranteed (0~+5W).
High Efficiency at High Temperatures
The low thermal coefficient produces greater energy production at high operating temperatures. The module provides a high energy yield at low NOCT = 45°C ( ±2°C).
Quality and Reliability
High-quality assurance due to stringent quality control. Greatly reduced PID susceptibility. .
Slow Power Degradation
A low 0.55% annual degradation rate after an initial first-year degradation of less than 2% is made possible due to low LID Mono PERC technology and results in a performance guarantee no less than 84.7% of the nominated power by year 25.
Enhanced Frame Design
The module’s 40 mm frame design provides easy installation and ensures robust mechanical strength. It is able to withhold a heavy snow load up to 5400 Pa and wind loads up to 2400 Pa. This module passed rigorous ammonia and salt mist resistance tests, which makes it an excellent choice for installations in harsh environments such as farms and seaside. This module is adaptable for the installation in hot and highly humid areas.
10 Year Product and 25 Year Performance Warranty
This module comes with a 10-year product warranty on materials and processing and a 25-year extra linear power output warranty.
