Are solar panels a viable option for domestic electricity production?

Solar panels are appearing on more and more rooftops around our suburbs as solar photovoltaics (PV) become an increasingly viable option for domestic electricity production. Photovoltaic solar cells, such as those in these rooftop panels, convert light directly to electricity. Image source: Marufish / Flickr. But how exactly does it work?

Are solar panels good at converting sunlight to electricity?

Solar panels are not very good at converting sunlight to electricity. Most solar panels are about 20% efficient. That means only 20% of the solar energy it collects is converted into electrical energy. But even this is a big improvement on how it was only ten years ago and there is more good news on the horizon.

What are solar energy systems & how do they work?

Solar energy systems come in all shapes and sizes. Residential systems are found on rooftops across the United States, and businesses are also opting to install solar panels. Utilities, too, are building large solar power plants to provide energy to all customers connected to the grid.

Is solar energy a viable alternative to fossil fuels?

Solar energy is likely to continue to exist so far into the future that we can think of it as being unending. Essentially, it's renewable, unlike fossil fuels which are running out as we use them. In addition, using solar energy doesn't cause air pollution or involve damaging the Earth's surface.
