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.

Tesla Gigafactory 1 Grand Opening

gigafactory-roof-rear-motortrend

On July 29th Tesla held the grand opening of their new factory, the Gigafactory. When it will be finished in 2020 it is supposed to have the largest footprint of any building in the world. As of now, it has only 3 of the final 16 sections build (the 4th one consist of raw steel beam frame) this translates to 14 percent of the expected final factory size. By this time Tesla in partnership with Panasonic had spent $431 million on Gigafactory while the planned total investment is estimated to be around $5 billion.

The factory is being built in stages.

The first sector is fully operational with machines on one side (robotic arms and very big machines responsible for cathode or anode processing) and designers on the other (separated only by hip-height dividing wall).

section 1

The second sector consist of fully prepared space (painted walls in place) and machines being assembled.

The third section is construction site where walls are being painted and assembled.

The third as mentioned earlier consist only of raw steel beam frames.

What is so innovative in this factory is the pursuit of manufacturing perfection. The huge design team working on the site, next to robots, is planning how to space out everything as efficient as possible.

Elon Musk expressed that if the designer’s team would concentrate their efforts on improving batteries itself their success would be marginal but when they were used to improve the efficiency of production their impact improved the performance by a factor of 3.

This only shows that not only designing innovation is important but also its manufacturing process as it might decide whether it will be cost-effective or not and potentially by used even in marketing like it is in this caseJ.

What brings the progress, in this case, is not the fact of building batteries but rather building batteries with zero defects and best possible efficiency. Those processes are as much important as improving the quality of cars or rockets (the two other things managed by Musk).

The scale and efficiency of this project will decrease the cost of batteries and in turn, decrease the cost of electric cars. This might lead to the popularization of all electric cars as more and more people will find them affordable.

Ps. I used Gigafactory 1 in the title as Musk plans to open more of them around the world to cut the costs of transporting batteries.
