Two Years Riding my BMW C Evolution and 20,000 km

20/06/2014 - 20/06/2016 That's 2 years now
(Last year's post: http://www.myelifenow.com/2015/07/already-one-year-with-bmw-c-evolution.html)

This year I used only my C Evoultion to commute, no LEAF at all even in winter






During last fall, with my son's GoPro, we made some onboard videos, in Paris, on the freeway, and that was fun




More videos on my Youtube Channel : https://www.youtube.com/user/chris75sf/videos

I also got my grand father sitting on the scooter for a rare fun picture :)

Many colleagues are interested in buying one, and the price is still the problem for them, I usually answer that I did not have the money to buy it back then and got a loan and pay 252 EUR per month over 6 years; I do not regret it ...

I often tell them to get it used: You can now get one with 3,000 km for 2/3 of the retail price: It's a very good deal !

Ready for summer now :)

DIY ESS Update : 500 EUR of SAVINGS logged but 720 EUR since the beginning

Goods News for my DIY ESS - Energy Storage Sytem : Another step reached with 500 EUR of Savings logged by the online portal as of this weekend :)

Since I started logging usage + generation data with the EnergyHive hub in June 2014, it says 502 EUR has been saved on Imported Electricity

But my DIY ESS has been running with Solar Panels since July 9, 2013, and the additional savings figure for the first period should be close to 11 x 20 EUR/month = 220 EUR

So the total amount of Energy Saved on my Utility bill is today around 720 EUR ! after 2 years and 9 mobths of service
And since the price per kWh of Electricity is always going up, the savings will continue to increase faster with time !

Even if I do not care about ROI really, I can now say that 1/4 of the money spent to build my DIY ESS (3,000 EUR) has been payed back in Energy Bill Savings (720 EUR) over the 2 years and 9 months : 720 / 3,000 = 24%


Using cheaper Electricity rates to Charge at night (TOU) during winter, and Solar Surplus during the day, my Energy Storage System automatically tries to match the Power Consumption at home, in conjonction with Solar Generation when available, to have a Net Usage (Home Usage - Generated Power) close to 0W : No Import & No Export = Self Consumption of Solar Production

EnergyHive Free Online Portal enables instructive and user friendly graphs for real time and historical data display

I often checks that my ESS is working fine during the day, using my iPhone, Mac, PC on http://wattson.energyhive.com/dashboard/diyesskit

Another real time way of checking what's going on is through a Logitech Broadcaster Webcam displaying Live on Ustream 2 Wattson units : one with Generation (Solar + ESS), the other with Net Usage (Usage - Generation) : http://www.ustream.tv/channel/chris75sf
