Can solar panels still provide good production on east- and west-facing roofs?

Many people believe that solar panels only work optimally on south-facing roofs, but modern panels are designed to produce efficiently even on east- and west-facing roofs. While south-facing is still ideal, the right installation can deliver an economically attractive output on other roof orientations.

How does the roof’s direction affect production?

An east- or west-facing system typically produces 80–90% of the energy compared to a south-facing roof. This is because the sun does not hit the panels as directly throughout the day, but today’s technology makes optimal use of the available light, even at lower sun angles.

Optimizing production

EcoRay always assesses the roof’s pitch, shading conditions, and other factors to place the panels as effectively as possible. Smart inverters and intelligent energy management ensure you get the most out of the electricity the panels generate, regardless of roof direction.

Economic and environmental benefits

Even with an east- or west-facing roof, you can significantly reduce your electricity bill and sell excess power back to the grid. At the same time, you actively contribute to the green transition and reduce your home’s CO₂ footprint.

Conclusion

Your roof’s direction does not have to be a barrier to investing in solar panels. With proper planning, intelligent control, and professional guidance, you can achieve both economic gains and environmental benefits—even on roofs that are not facing south.
