By answering trivia questions about renewable energy, players earn “solar panel” points that put them in the running for some great prizes – and learn a lot more about solar power along the way.
The more you learn, the more points you win and the more likely you are to win the top prize: a solar power system worth $25,000. This can be added to the winner’s home or gifted to a family member, friend or community building such as a school.
There are regular draws to win more than 60 smaller prizes, including video cameras, gift cards and gig tickets .
“Badges” can also be won and posted on to players’ Facebook walls.
Launched last month, the game and competition run until 14 September.
