In an era increasingly focused on sustainable energy, solar panels have emerged as a prominent symbol of the clean energy transition.

You probably already know that solar panels use the sun's energy to generate clean, usable electricity. But have you ever wondered how they do it?

If you’ve been considering installing rooftop solar panels, you might have some unanswered questions about the process like how much solar do I need or what is the cost of installation. Finding answers can be difficult and confusing.

Solar panels respond to both direct sunlight coming straight from the sun and diffuse sunlight reflected from particles in clouds and the atmosphere. Solar panels are usually able to generate some electricity even on a cloudy day. However, most electricity is produced on clear days when direct sunlight hits the panels.
