Who found solar energy?
A solar cell is a device that converts light directly into electricity using the photoelectric effect. The first solar cell was constructed by Charles Fritts in the 1880s.
How do we convert solar energy into electricity?
When light energy from the sun strikes a photovoltaic solar cell, it energizes the cell and causes electrons to ‘come loose’ from atoms within the semiconductor wafer. Those loose electrons are set into motion by the electric field surrounding the wafer, and this motion creates an electrical current.
Can you clean solar panels on a hot day?
Solar panels can become incredibly hot in sunshine. Either clean your solar panels in the morning/afternoon, or pick a relatively cool day. Try using a garden hose first; that alone might handle the job. However, if a lot of dust and dirt has accumulated, you might need to give them a more thorough clean.
Do dirty solar panels generate electricity?
How Much Production Are You Losing with Dirty Panels? Anything that comes between your solar panels and the sun will have an impact on how much electricity the system produces. In the case of typical dirt build up on solar panels, the reduction in production is so small that it’s hardly ever worth taking action.
How often should solar panels be serviced?

What is the lifespan of a solar inverter?
around 10 years
Is it worth upgrading my solar?
There are many reasons an older (or even a recent) solar system might need an upgrade. While most grid-connected solar panels should have a long life of 20 to 25 years, panels can fail early. But, given that, it’s likely you’ll need to replace your solar system’s inverter at some point in the life of the system.
