How to save 92% on your electricity bill? [CASE STUDY]

Just about 4 months ago Tesla officially announced acquisition of SolarCityclick . Many people consider this as a giant leap towards bringing solar energy to the masses. Today we finally have a real-life case study of Tesla’s revolutionary solar system in use and it’s undeniable that Elon Musk’s company is on the right track to lead the solar energy revolution.

This week, a well-known consumer advocacy portal CHOICE – click, published an article describing the story of an Australian Tesla fan who used the Powerwall battery for the past year and experienced its saving potential.

Powerwallclick is a smart lithium-ion energy storage pack designed and produced by Tesla Inc. In short, this product is a battery pack for your home that stores energy from photovoltaic panels and delivers sustainable electricity, even when the sun isn’t shining. Powerwall is a great backup power device but it also gives the user the ability to sell excess of energy back to the grid. With its power management system, Powerwall is able to significantly decrease household energy bills spending.

 

The best proof for Tesla’s solar system cost cutting capabilities is the story of Nick Pfitzner described in CHOICE articleclick. Nick lives with his family in a four-bedroom home in Kellyville Ridge, Australia. This large residence is equipped with atelier, laundry, outdoor entertainment area and its own pool. Powering this home with electricity in 2015 cost Nick $2289 but in January 2015 Nick decided to invest in sustainable energy system. Nick invested $16,790 in buying 7kW Powerwall battery, a 5kWp solar array, a SolarEdge inverter and a Reposit monitoring system.

After implementation of this system Nick’s average quarterly bill dropped from $572 in 2015 to $45 in 2016. After a year of using his new power system Nick was able to save 92% on his annual electricity expenses. His annual electricity bill has dropped from $2110 in 2015 to $178.71 in 2016. This level of efficiency surprised the owner himself: “Before I crunched the numbers I was looking at what would be my return on investment. If it saved me 80% of my power bill, [I thought] it would be pretty good,” he says. Outstanding efficiency of Nick’s system topped original Tesla Inc projections estimating that their solar systems can pay itself off within 14 to 18 years. If Nick’s solar system will continue operating at this rate it will payback in just 8 years.

Isn’t it marvelous?

 

Remarkable results of Nick’s power system will undoubtedly ignite already booming market of solar power systems. This combined with Tesla’s progressing plan of building 3 more Gigafactiories – click in order to increase supply and lower costs of batteries and photovoltaic panels only amplifies the strong belief that solar will power our future.

THE ERA OF INTEGRATED SUSTAINABLE ENERGY JUST BEGUN!

TESLA OFFICIALLY AQUIRES SOLARCITY.

Couple weeks ago (28.10.2016) Tesla in cooperation with SolarCity presented new solar powered ecosystem for private houses and small businesses. Tesla’s new green energy system is entirely sustainable and more cost-effective than regular grid system.

 

Power generating Roof Tiles are more durable, less costly and almost indistinguishable from traditional roofs. With this design and cost-efficiency Tesla is undeniably a forerunner in emerging market of accessible photovoltaic roofs.

That day Tesla also announced Powerwall 2, energy storing lithium-ion batteries for private use. Powerwall 2 is capable of powering a two-bedroom house for 24 hours entirely without power from the grid. Tesla’s approach to product design is also very visible with this one. Powerwall 2 has very aesthetical design making it the most elegant home battery on the market.

Tesla’s solar system allows households to be more energy independent and save thousands dollars on their annual energy bill. According to Bloomberg New Energy Finance, the Powerwall 2 “may be the cheapest lithium ion battery for the home ever made.” This is making Powerwall 2 an approachable home battery system of now and today.

Solar Roof and Powerwall 2 combined with Tesla’s electric cars creates cost-efficient, zero-emission ecosystem of the future.

Tesla new ecosystem presentation caused widespread buzz in the media and was a first sign of upcoming event.

Last Monday (21.11.2016) Tesla acquisition of SolarCity was officially announced.

SolarCity is the biggest provider of commercial solar panels in the United States. It has its own direct sales force and the best installation team in the industry. Moreover, SolarCity has developed innovative financing options making solar energy more accessible and affordable.

 

Just one day after the acquisition Tesla published this mind blowing one-minute video showing their new solar-powered microgrid that can supply whole energy demand of beautiful Tau Island located in American Samoa.

Thanks to combined effort of Tesla and SolarCity Tau Island is able now to entirely abandon diesel generators and become sustainable, remote Island powered fully by renewable energy.

 

Acquisition of SolarCity made Tesla a truly integrated sustainable energy company. They are now able to produce energy (Solar Roofs), storage it (Powerwall 2) and efficiently use it for transportation (Tesla cars). With those resources Tesla is giving people possibility of living zero-emission, entirely sustainable, green lifestyle.

This is the beginning of revolution in the way we produce and consume energy and Tesla just made another big step towards the world free of fossil fuels.
