Solar power for dummies

What is solar power and how does it work?

Solar power works through Photovoltaic (PV) cells, which convert light into usable electricity. This technology has been around since the mid-1800s and is not as complex as some people might think.

How do solar panels generate electricity?

Solar panels generate direct current (DC) energy. However, this DC power cannot be used to directly power your home. Therefore, it is sent to a power inverter, which is connected to the back of the solar panel. The inverter's job is to convert this DC power into alternating current (AC).

When will solar energy be a major source of electricity?

International Energy Agency is expecting solar energy to be a major source of electricity by 2050. They may not produce as much energy as a nuclear power plant, but the efficiency is improving. Cities all around the world are quickly adopting solar power.

What are the different types of solar power?

The most common type of solar power technology most of us are familiar with is photovoltaic, which uses sunlight. Solar panels rely on the photovoltaic effect to produce electricity. But there is a second type of solar power - concentrating solar-thermal power or CSP. CSP also harnesses sunlight, but converts it into heat instead of electricity.

Do solar panels go to waste?

One of the great things about solar power systems is that any excess power you generate doesn’t go to waste. Instead, it’s fed back into the main power grid. In many parts of Australia, you can receive credits on your power bill for this excess electricity. Solar panels only generate power during the day.

How efficient are solar panels becoming?

Solar panels are attached to satellites and launched into space, it IS space-age technology. They will last for a good 30-50 years when maintained properly. The efficiency is improving, but they may not produce as much energy as a nuclear power plant. Cities all around the world are quickly adopting solar power.
