At SunPower by South Coast Solar, we frequently hear this question: "Why should I invest in solar panels now? They will have something better next year right?" The answer is yes and no.
Yes, solar panel power ratings will continue to rise slowly and no, there is no "game-changing" solar panel technology just around the corner that's going to make solar "better than free." What's really exciting is today's technology is already changing the game!
The SunPower® solar cell design is fundamentally different from all other solar cells. The proprietary "back-contact" cell design allows all the electrical circuitry to be located on the back of the cell, thereby exposing more silicon to the sun's rays. All other cell designs feature electrical contacts on the front of the cell which block sunlight.
