A few months ago, Tesla unveiled a solar system that was built right into the roof tiles themselves, but if you're not looking to retile your entire roof, the company is now offering an after-market solar system. The announcement was quietly made this weekend when Tesla updated its website – a fitting reveal, since the new solar panels are designed to blend into an existing roof without causing a fuss.

While the energy-capturing tiles look like a great option for people building a new house, they don't really serve people who don't want to rip up their existing roof. Those customers could shop elsewhere, of course, but Tesla's new system is designed to integrate easily into the company's home battery, the Powerwall, and be particularly modest-looking in the process.
