How did solar energy develop?
It wasn’t until the 19th century that we began turning the sun’s light into electrical energy. In 1839, French Physicist Alexandre Edmond Becquerel discovered the photovoltaic (PV) effect. … The space race created a need for sustainable energy sources. It steered investments and development in the solar industry.

How many solar panels do you need to power a house?
How many solar panels do I need to power my house? The typical homeowner will need 28 – 34 solar panels to cover 100% of their energy usage (dependent on location and roof size). To get these numbers, we used high and low panel production ratios to calculate how many solar panels are needed on average.
