Photovoltaic panels blown down in the desert

What would happen if we covered the Sahara Desert with solar panels

So, the idea is that if we could gather all that energy, we could power the world. In reality, we would harvest so much more energy than we could ever possibly need. According to Forbes, solar panels covering a surface of around 335km 2 would actually be enough to power the world – this would cover just 1.2% of the Sahara Desert. What would

Why Don''t We Cover The Entire Sahara Desert With Solar Panels?

By building such a battery pack under the solar panel, you can avoid taking up any more space. Each solar panel has its own small battery to keep it powered day and night. Approximately 4.2 kWh of storage battery should be added to each panel (12 hours at 350 W output). This adds about $900 to the cost of each panel.
