High-Performance Solar Panels for Home & Business

Efficient PV modules for your photovoltaic system

Solar panels are the foundation of every photovoltaic system and enable you to generate your own solar power in an environmentally friendly and cost-efficient way. Homeowners who invest in solar panels can significantly reduce electricity costs, increase their independence from energy suppliers, and contribute to a sustainable energy future. Modern photovoltaic modules offer high efficiency, long service life, and attractive prices – making them ideal for residential rooftops and smaller solar installations.

In our online shop, you can conveniently buy solar panels, inverters, battery storage systems, and accessories online, all perfectly matched to a wide range of requirements. Whether you are looking for high-performance PV modules for limited roof space or particularly durable solar panels for long-term investments – you will find the right solution here.

Which solar panels should you buy? – The most important selection criteria

Choosing the right solar panels depends on several factors. In addition to the available roof space, your electricity consumption and the overall goal of the photovoltaic system are crucial – for example, maximizing self-consumption or achieving the highest possible system output.

When buying solar panels, you should pay particular attention to:

• the power output in watt-peak (Wp)
• the efficiency of the solar panels
• module size and appearance
• quality, warranty, and manufacturer

The power output in watt-peak (Wp) indicates how much electricity a solar panel can generate under optimal conditions and serves as an important reference value for the total output of your photovoltaic system. High efficiency ensures that more solar power can be generated on the same surface area, which is particularly important when roof space is limited. Module size and appearance are especially relevant for visible roof areas, as larger modules require more space and influence the overall visual impression. Quality, warranty, and the manufacturer are key factors for the longevity and reliability of solar panels, as high-quality modules deliver stable yields over many years and are backed by long warranty periods.

For particularly easy system planning, we also offer preconfigured PV complete systems from 6 to 16 kWp with perfectly matched solar panels, making the selection process much easier.

Types of solar panels – which technology is right for you?

Monocrystalline solar panels

Monocrystalline solar panels are among the most efficient PV modules on the market and have become the standard choice for residential applications. They are made from a uniform crystal structure and achieve particularly high efficiency levels. This makes them ideal for residential photovoltaic systems with limited roof space. In addition, monocrystalline solar panels offer a long service life and very low performance degradation over many years.

Glass-glass and glass-foil solar panels

Glass-glass solar panels are especially robust and durable. They are protected by glass on both sides and are highly resistant to environmental influences such as moisture and temperature fluctuations. Glass-foil solar panels are lighter and often more affordable, while still delivering very good performance. Both module types are well suited for residential solar installations.

Bifacial and full black solar panels

Bifacial solar panels can generate electricity from both the front and the rear side of the module, allowing for increased energy yields. Especially when installed above reflective surfaces or on elevated mounting systems, bifacial PV modules can achieve higher overall output compared to conventional solar panels. These modules are often designed as glass-glass solar panels and stand out due to their high efficiency and long service life.

Full black solar panels are primarily chosen for their uniform black appearance and are particularly popular for residential buildings where aesthetics play an important role. With their completely dark surface, these solar panels blend seamlessly into modern roof designs while still providing reliable performance for residential photovoltaic systems.

Power output and watt-peak – how much output do solar panels need?

The output of solar panels is specified in watt-peak (Wp). For residential photovoltaic systems, solar panels with 400 Wp, 430 Wp, or 450 Wp are especially popular. The higher the Wp rating, the more electricity a single panel can generate.

The required number of solar panels depends on:

• your annual electricity consumption
• the available roof space
• the desired total output of the PV system

High-performance solar panels make it possible to use even smaller roof areas efficiently while achieving high energy yields.

High-quality solar panels from well-known manufacturers

Quality plays a crucial role when purchasing solar panels. High-quality photovoltaic modules provide stable energy yields, a long service life, and comprehensive warranties. Many manufacturers back their solar panels with product warranties of 15 to 30 years, along with additional performance guarantees.

Our range includes solar panels from renowned manufacturers such as Trina Solar, JinkoSolar, LUXOR Solar, and many more. These brands stand for modern cell technologies, reliability, and high manufacturing quality – ideal for residential photovoltaic systems.

Frequently asked questions about solar panels

Frequently Asked Questions about Solar Panels

Which type of solar panel is the best?

For most residential photovoltaic systems, monocrystalline solar panels are considered the best choice today. They offer high efficiency, excellent use of available roof space, and a long service life. Especially when roof space is limited, monocrystalline PV modules are ideal, as they generate more solar power per square meter than other types of panels.

How long do solar panels last?

Solar panels typically have an average service life of 25 to 30 years. Even after this period, they continue to generate solar power, although with slightly reduced output. Over time, the performance of the modules gradually decreases, a process known as performance degradation. Modern photovoltaic modules usually lose only around 0.3 to 0.5% of their output per year and still deliver approximately 80 to 85% of their original power after 25 years. Many manufacturers further support this with long-term performance warranties.

How many solar panels do I need for a single-family home?

The number of solar panels required depends on electricity consumption, available roof space, and the desired output of the photovoltaic system.

Do solar panels require a lot of maintenance?

Solar panels are very low-maintenance. In most cases, an occasional visual inspection is sufficient to ensure consistently high energy yields.

How many solar panels do I need for a single-family home?

The number of solar modules required depends on electricity consumption, roof area, and the desired output of the photovoltaic system. It is therefore not possible to make a blanket statement here, as it depends heavily on the objectives pursued with the PV system.

How are solar panels mounted (pitched roof or flat roof)?

The mounting of solar panels depends on the type of roof. On pitched roofs, PV modules are typically installed using special mounting rails and roof hooks on tiled, concrete, or metal roofs. For flat roofs, mounting systems with angled frames are commonly used, positioning the panels at an optimal tilt angle and often secured with ballast. Both mounting methods are durable, stable, and specifically designed for the respective roof type.
