Electricity prices in Australia are set to rise again, with the Australian Energy Regulator confirming a 20% increase coming into effect from July.

"The challenge for the electricity industry is the solar systems … if they are putting a lot of power back into the grid and nobody is really using much power in the middle of the day, there's the problem," Professor Sproul says.

"So, we need to balance supply and demand. That's why they're paying less for solar as time moves on."
