JA Solar modules for balcony power plants and photovoltaic systems

JA Solar is one of the world's leading manufacturers of solar modules and offers PV modules for a wide range of requirements. At PVundSO, you'll find JA Solar modules in power classes from 440 to 500 watts, suitable for balcony power plants as well as larger photovoltaic systems up to 20 kW. JA Solar modules feature bifacial cell technology, where both sides of the module contribute to power generation. JA Solar modules are available in various designs, including all-black versions with a black frame for an aesthetically pleasing roof installation.

Our product range includes complete sets with microinverters for direct connection, as well as individual JA Solar PV modules for building customized systems. JA Solar balcony power plant options start at just €249 and offer an easy entry into decentralized power generation. Larger PV systems with JA Solar modules achieve outputs of 3 to 20 kW and are equipped with string or hybrid inverters. All JA Solar module types undergo functional testing and comply with the current VDE standards for photovoltaic systems.

Reduce energy costs in the long term with JASolar solar modules

Investing in JA Solar PV modules pays for itself through continuous self-generated electricity over a period of 25 years or more. A JA Solar balcony power plant with two 445-watt modules generates between 800 and 1.000 kWh per year, depending on the location. At an electricity price of €0,35 per kWh, this equates to annual savings of €280 to €350. Larger solar systems with JA Solar PV module configurations of 3 to 10 kW reduce electricity costs even more significantly and typically pay for themselves within 8 to 12 years.

JA Solar technology solar modules impress with efficiencies of up to 21,5 percent and minimal power degradation of less than 0,45 percent per year. The bifacial JA Solar PV module variants utilize additional reflected light from the back, increasing the annual yield by 5 to 15 percent compared to monofacial modules. JA Solar panels with a nominal power of 500 watts enable compact system configurations with fewer modules while maintaining the same total output. All JA Solar modules come with a 15-year product warranty and a 30-year linear performance warranty guaranteeing at least 87,4 percent residual power. We deliver JA Solar modules free of charge within 5 to 8 business days.

High-quality PV modules from JA Solar for versatile applications

JA Solar PV modules are suitable for stationary rooftop installations as well as for mobile applications on motorhomes or garden sheds. The robust JA Solar solar panels withstand snow loads of up to 5.400 Pascals and wind loads of up to 2.400 Pascals, making them suitable for all climate zones in Germany. Bifacial JA Solar module designs achieve higher yields on light-colored surfaces such as gravel or concrete due to back-side light absorption. Full-black JA Solar modules blend harmoniously into dark roof surfaces and often meet even the strictest requirements for listed buildings.

We offer JA Solar module types in various system configurations. Our balcony power plant kits include not only the PV modules but also microinverters with 600 or 800 watts output power and the necessary connection cables with MC4 connectors. Complete PV systems with JA Solar modules include string inverters from Solis or Sofar with Wi-Fi monitoring, and optionally hybrid inverters with battery storage capacities from 4,8 to 20,48 kWh. For hot water applications, we combine JA Solar panels with DC heating elements from my-PV, which directly utilize excess solar power for thermal energy production. Our delivery includes all components for a fully functional system, including installation instructions.

High-performance JA Solar PV module technology with bifacial design

JA Solar's bifacial cell technology in PV modules is based on PERC cells with continuous aluminum back contacts. This design allows light to be captured on both sides of the module, increasing efficiency by up to 30 percent compared to front-side capture alone. JA Solar modules in the JAM54D40 and JAM60D41 series utilize half-cell technology with 144 and 160 cells, respectively, minimizing shading losses and reducing hot-spot risks. The 9-busbar connections between the cells lower ohmic losses and increase mechanical stability.

JA Solar PV modules with 445 watts achieve a module efficiency of 21,4 percent under standard test conditions of 1.000 W/m² and 25°C. The temperature-related power reduction is only 0,34 percent per Kelvin above 25°C, making JA Solar modules suitable even for sunny locations with high operating temperatures. JA Solar modules in the 500-watt class deliver more power with the same module area thanks to optimized cell geometry and improved anti-reflective coatings. The 3,2 mm thick tempered glass surfaces withstand hailstones up to 25 mm in diameter at an impact speed of 23 m/s. JA Solar panels meet the IEC 61215 and IEC 61730 certifications for PV modules, as well as fire protection class C according to EN 13501-1.

Yes, solar panels and accessories are available in various performance classes.

Our product range includes JA Solar modules with peak power outputs from 440 to 500 watts. Individual modules from the JAM54D41-LB series with 440 watts cost €79 and are suitable for the gradual expansion of existing systems. The 445-watt variant, JAM54D40-LB, offers a black frame design at the same price and allows for aesthetically pleasing installations. More powerful JA Solar modules with 500 watts, from the JAM60D41-LB series, are available for €99 and reduce the number of modules required and the installation time for larger projects.

For installation, we offer suitable mounting systems for tile roofs, flat roofs, bitumen roofs, and balcony railings. JA Solar solar panels are supplied with the necessary MC4 cables, ensuring a weatherproof and touch-safe connection. Complete JA Solar balcony power plant sets with two modules and a microinverter start at €249 and include all components for commissioning. PV systems with 3 kW, consisting of six 500-watt JA Solar PV modules and Solis string inverters, are available for €999. Larger systems with hybrid inverters and battery storage enable complete energy self-sufficiency and are configured as turnkey packages.

Frequently asked questions about JA Solar

What warranty do JA Solar modules offer?

JA Solar modules come with a 15-year product warranty on materials and workmanship. In addition, there is a 30-year linear performance warranty guaranteeing at least 87,4 percent of the nominal power output. After 25 years, the guaranteed minimum power output is still 84,8 percent.

What does bifacial mean in the context of JASolar solar modules?

Bifacial JA Solar PV modules generate electricity from both their front and back sides. The back side utilizes reflected light from light-colored surfaces such as gravel, concrete, or white roofs. This increases the annual yield by 5 to 15 percent compared to conventional monofacial modules.

Are JA solar modules suitable for balcony power plants?

Yes, JA Solar modules are ideal for balcony power plants. We offer complete JA Solar balcony power plant sets starting at €249, including two modules and a microinverter. The compact 445-watt modules are easy to install on balconies, terraces, or garage roofs and provide usable solar power immediately.
