卡通风绿色能源房屋场景插画素材

Bright and cheerful environmental poster for residential solar power. High-key color palette: warm sunny yellow, sky blue, and crisp white. Central illustration: a simple house with shiny solar panels on roof, sun rays in pale yellow, all hand-drawn style. No 3D, no glossy photorealism. Matte, slightly textured paper feel but with much lighter and airier background. No dark shadows. Chinese text: main title "屋顶有光，账单不慌", statistics in clean box. Bottom right: QR code placeholder with light gray pattern and text "扫码测算收益". Overall feel like a positive community flyer, open and inviting. Aspect ratio 2:3.
