Seven common misunderstandings about household savings that you must know

1. Shadow influence:

Myth: Many people believe that shading has a minimal effect on solar panels.

Principle: Even a small area of ​​​​shading will significantly reduce the power generation efficiency of the panel, especially when the shading covers the short sides of the panel, which may cause the output power of the entire panel to decrease. Shadowing can cause uneven current flow, affecting overall system performance.

2. Panel orientation:

Myth: There is a view that solar panels should be installed facing west to match the peak power consumption in the afternoon.

Principle: The optimal orientation should be determined based on specific power usage patterns and geographic location. While west-facing panels can improve afternoon generation in some cases, south-facing panels generally provide more consistent generation year-round.

3. Best tilt angle:

Myth: A common saying is that panels should be tilted at the same angle as the local latitude.

Principle: The optimal tilt angle should be adjusted according to the season and power demand. In winter, when the sun is lower, a larger tilt angle may be needed to capture more sunlight.

4. Over-configuration of photovoltaic systems:

Myth: Thinking that over-provisioning PV systems will lead to wasted electricity.

Principle: Appropriate over-provisioning can ensure that power demand can still be met on cloudy days or high temperatures. Over-provisioning can provide additional power during times of high demand, especially during the summer.

5. Effectiveness of southbound panel:

Myth: South-facing panels are considered the only best option.

Rationale: In some cases, an east-west panel mix can provide a smoother generation curve, especially in areas with higher demand for own electricity. East-west panels better match daytime power usage patterns.

6. Standardization of connectors:

Misunderstanding: Thinking that solar connectors are standardized and all brands of connectors are interchangeable.

Principle: Connectors of different brands may be incompatible, and mixed use may lead to malfunctions and safety hazards. Standard regulations require connectors to be of the same type and brand to ensure safety and reliability.

7. The necessity of battery energy storage:

Myth: Thinking that all solar systems need to be equipped with battery storage.

Principle: Whether a battery is needed depends on the design of the system and the user’s power usage pattern. In many cases, it is more economical to use electricity generated directly from the sun, especially if it is connected to the grid.
