Is solar energy more expensive than conventional energy?

In many countries, solar systems produce electricity at or close to the cost of electricity from other conventional sources, which continue to rise. When the cost of solar electricity matches the cost of conventional energy, we refer to this as “grid parity”. In NZ "grid parity" is only a few years away.

The more recent increases in electricity bills and the parallel reduction in the cost of solar power systems means that most home solar power systems are paid off in 5 to 7 years. A high quality solar panel can generate power for more than 25 years (Please consider that panels can last that long, but inverters likely require a replacement in such a time frame).

In the past governments around the world have provided financial support for solar energy in many countries in recognition of its important role and because it avoids reliance on fossil fuels.

Solar energy production costs have been reducing due to improvements in technology and economies of scale.
