In another extravagant launch, billionaire Elon Musk revealed Tesla's new solar roof that is designed to change the power sources of future homes. The solar roof panels' debut was done at Universal Studios in Los Angeles no less last Oct. 28.

Tesla solar roof was released along with Tesla's Powerwall 2 and Powerpack 2. The release of Tesla's Solar Roof is a result of the company's acquisition of Solar City. The Solar Roof is designed to replace conventional roofing systems with solar tiles capable of harnessing the energy from the Sun.

This means, if a home's roof is made up of solar panels, the home will be able to harvest energy from the sun and store it in Tesla batteries. In the long run, the household will get free energy from the sun making it a viable investment compared to paying for electricity bills on a monthly basis.

Musk said that the cost would be lesser than the combined price of contemporary roofing and electric bills. However, the billionaire did not give the exact retail price of Tesla's solar roofs just yet.

But one of the good things to note though is Tesla's plan to give direct access and selling system from the company to the homes eliminating homebuilders thus making the cost of the solar roofs even lower.

During the launch, Tesla showcased its solar roofing system installed on the Desperate Housewives home set. To the surprise of the audience, Musk revealed that the house was fitted with the Solar Roof to which no one noticed until Musk pointed it out. The solar roof tiles look normal but of course more functional with energy harvesting capabilities compared to the usual roof tiles.

Musk also pointed out that the solar roofs can be placed in specific areas of the home while letting homeowners keep their preferred roofing styles in many other areas of the home. "People love their homes and we want them to be better," Tesla CEO Elon Musk said during the launch.

The household-powering capability will then depend on the batteries installed in a home. Based on Tesla's computation, a two 14kWh Powerwall with lithium-ion batteries can power house lights, fridge and other appliances in a four-bedroom home for an entire day.

The renewable energy sources and the tycoon's plan to stop using fossil fuels for energy is part of Tesla's Master Plan Part 2 that Musk revealed earlier this year.
