How do solar panel types differ?
How do solar panel types differ?
Solar panel types primarily differ in efficiency, technology, and application.
Previously widespread polycrystalline panels have now fallen out of favor due to their lower efficiency, especially in poorer light conditions.
Modern systems almost exclusively feature monocrystalline panels, which provide higher performance over a smaller area and offer a longer lifespan.
Within these, we distinguish between monofacial (producing only from the front) and bifacial panels. The latter also utilize light reflected from their back, thus enabling up to 10-20% greater energy production in appropriate installation environments.
Therefore, monocrystalline technology is now the best choice for most household systems.
Which solar panel should I choose for the inverter?
Which solar panel should I choose for the inverter?
When choosing solar panels, the most important aspect is compatibility with the inverter, but in practice, this is not complicated.
The panels are connected in series, so care must be taken to ensure that the voltage within a given MPPT input remains within the permissible range and does not exceed the inverter's maximum values.
However, in most cases, this is a readily manageable design issue and does not require significant compromises during selection.
The solar panels offered in our webshop are suitable for all inverters we sell, so you can freely choose based on performance, size, or price.
It is advisable to select the type that fits the available space and offers the best value for money.
What happens if one of the panels is shaded?
What happens if one of the panels is shaded?
If a solar panel is shaded, it can affect the performance of the entire system.
In a traditional (string) system, panels connected in series draw the same current, so a shaded panel can reduce the performance of the entire string.
However, this effect can be reduced or even eliminated by using optimizers. Optimizers regulate the operation of each panel individually, so a shaded panel does not significantly affect the performance of the others.
Therefore, if shading is expected during installation (e.g., chimney, tree, roof segmentation), it is worth considering an optimized system for more efficient operation.
How do tilt and orientation affect solar panel performance?
How do tilt and orientation affect solar panel performance?
The best production is achieved when sunlight hits the panels as perpendicularly as possible. In Hungary, a south-facing orientation and a tilt angle of approximately 35–40° generally provide the highest annual yield.
In the case of an east-west arrangement, the total production is typically 5–10% lower, but the energy distribution is more even throughout the day. This can be particularly advantageous in households where consumption is significant both in the morning and in the afternoon.
In practice, therefore, maximum peak production is not always the most important factor; rather, it is how well production aligns with consumption habits.
What kind of warranty comes with solar panels?
What kind of warranty comes with solar panels?
Most manufacturers provide a 12–15 year product warranty, covering manufacturing defects and reliable operation.
Additionally, a 25-year performance warranty is in effect, meaning that the panels retain a significant portion of their performance long-term, typically at least 80–85% even after two decades.
It is important to note, however, that the performance warranty is a long-term commitment that primarily serves as a safety net. In practice, technology evolves significantly over such a period, so in many cases, it may be a more economical solution to upgrade to a more modern panel than to go through the warranty claim process.
Therefore, when making a choice, it is advisable to prioritize the manufacturer's reliability and the current quality of the product.
