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
JA Solar 390w S09 Mono PERC 72-cell module. This high-performance PV module, powered by high-efficiency PERCIUM cells, offers the advantages of higher power output, reduced shading effect, better temperature-dependent performance, lower risk of hot spot, and enhanced tolerance for mechanical loading.
- 390W Power Output
- 19.5% Module Efficiency
- QC4 Connectors
- Low temperature coefficient
- 5 busbar solar cell design
- Excellent low-light performance
- Silver frame, white back
Higher Efficiency 19.5%
JA Solar 390w Solar Panel provides higher power output and greater energy harvest due to high-efficient PERC cell technology. Moreover, the module includes five busbar cell design, which improves low light performance.
Great Performance at High Temperatures
Lower temperature coefficient (-0.3%/°C) allows the panel to perform at high levels even at extremely high temperatures, which means more energy throughout the day.
Quality and Reliability
JA Solar has been considered Top Performer over the last years according to the PVEL Scorecard. The company conducts long-term reliability tests (mechanical load, HAST, thresher, etc.) and environment endurance tests (ammonia resistance, salt mist spray, damp-heat climate, etc.) which guarantee reliability of the products.
According to the tests conducted by TÜV SÜD, JA Solar 390w Solar Panel demonstrated less than 1% power degradation after experiencing temperatures of 85 degrees Celsius, 85% relative humidity, and 1,000 volts of system bias voltage, for a duration of 96 hours.
72 High-Efficiency Cells
The panel is assembled with 72 (6 x 12) monocrystalline cells to ensure bigger solar energy yields.
Maximum 25-Year Warranty
JA Solar has an impressive 12-year product and 25-year performance warranty for all of their solar panels. The performance of JA Solar 390w S09 Mono PERC is warrantied for 83.1%.
