PERC solar panels are solar panels manufactured with PERC cells (Passivated Emitter and Rear Cell). The additional layer on the back of PERC solar panels captures more sunlight, converting it into electricity, making PERC cells more efficient than traditional cells. PERC modules also reduce backside recombination and prevent longer-wavelength heat from affecting cell performance.

PERC solar panels

While PERC technology has been around since 1989, commercial implementation faced challenges due to light-induced degradation. However, with steady improvements over the years, PERC modules now have efficiency rates 1% higher than standard modules. Given that standard modules typically have around 20% efficiency, systems using PERC modules can generate approximately 5% more energy under similar conditions. Like other high-efficiency components, PERC modules are ideal for maximizing production in limited roof space. If you're installing on partially shaded small roof areas or buildings, PERC modules are a good choice.

Even if roof space isn't a primary concern, using more efficient PERC modules can save installation time and costs. Currently, a significant portion of the solar panels on the market belongs to the category of PERC solar panels.

Germany's Solar Panels

Germany, globally renowned as the pioneer in the energy transition, maintains a stellar record in the proficiency of solar energy technology. The photovoltaic industry in Germany began to snowball around 2010, which heralded the era of extensive photovoltaics public adoption. Despite facing challenges following the subsidy slash post-2014, the proportion of renewable energy generation in Germany sat at an impressive 43% of the total electricity generated in 2019, surpassing the initial 35% target set for 2020.

Roof-mounted photovoltaics, which make up for a staggering 80% of the total installations, are the primary methodology adopted for the promotion and popularization of solar energy in Germany, and are deemed as a critical element of the country's energy transition.

the most widely used photovoltaic panel components in the European market are solar panels made of crystalline silicon materials. These panels are primarily fixed using photovoltaic panel brackets, and users can choose different specifications of photovoltaic components based on their home load requirements.

 Solar panels available in the market offer various advantages, including power generation capability, high strength, strong safety features, water resistance, aesthetic design, energy efficiency, easy installation, long lifespan, minimal maintenance, excellent lighting, shading and cooling effects, as well as safety and reliability.

Characteristics of Solar Panels for Apartment Balconies

"Roof-mounted photovoltaics are the main means of promoting and popularizing solar energy in Germany, accounting for nearly 80%. It is considered a crucial component of Germany's energy transition and has formed a unique landscape in the country." In recent years, rooftop photovoltaic construction has reached a certain level, and Germany has introduced balcony photovoltaics. The balcony photovoltaic system is called "balkonkraftwerk" in Germany, which literally means installing photovoltaic system on the balcony. It belongs to the ultra-small distributed photovoltaic system. Due to the reduced installation area, the selection of photovoltaic panels for the balcony photovoltaic power station is stricter.

The following are the selection characteristics of Solar Panels for Apartment Balconies.

  • High Efficiency: Choose high-efficiency photovoltaic panels to effectively convert sunlight into electricity within the limited balcony space.
  • Compact Size and Lightweight: Balcony spaces are limited, so opt for relatively small-sized and lightweight solar panels that can better fit into the constrained installation space and reduce the burden on the balcony structure.
  • Durability and Long Lifespan: Choose durable solar panels with a longer lifespan to minimize maintenance and replacement needs. High-quality materials and manufacturing processes ensure excellent performance in outdoor environments.
  • Adaptability: Solar panels should demonstrate good adaptability, maintaining stable operation under different weather conditions. Factors such as wind resistance, moisture resistance, and temperature tolerance need to be considered.
  • Waterproof and Sunproof: Since solar panels will be exposed to outdoor elements for extended periods, having excellent waterproof and sunproof properties is crucial. This helps ensure the system operates normally under various weather conditions.
  • Ease of Installation and Maintenance: Choose solar panels that are easy to install and maintain, reducing installation costs and the complexity of post-installation maintenance.

How to Get Free Electricity Illegally: A Myth Debunked

Yes, the topic of "How to Get Free Electricity Illegally" must can only be a myth. However, we can indeed obtain electrical energy through alternative means, apart from purchasing electricity from the grid. Just like large-scale thermal storage for heat or wind power generation, we can generate electricity by harnessing solar energy.


You can establish your own rooftop solar and storage system. If the roof space is limited or if you are renting an apartment, you can also opt for a solution involving balcony solar panels with energy storage batteries. Despite the small size, balcony solar panels provide a convenient and cost-free way to obtain electrical energy.

If you are planning to install a balcony solar system on your roof or balcony, you can come here to find products that suit your home.
