Rooftop Energy

Solar PV costs have fallen about 90% over the last decade. Modern home solar panels often exceed 20% efficiency, with typical residential systems of 5–10 kW. In the United States, over 4 million homes had solar panels by early 2024. Global rooftop PV adoption could reach about 100 million households by 2030. In the United States, the rooftop solar roofing market is projected to reach nearly $1 billion by 2025, as California mandates solar on almost all new homes starting in 2023. A Dutch startup unveiled the Blade X1 rooftop wind turbine at 1.4 meters tall, generating about 2,500–3,000 kWh
