Have you seen an all-electric commercial airplane before? Neither have we or anyone. But Luke Workman, a highly regarded battery designer, thinks that he has an idea that will make that become a reality in the not so distant future. He hopes to accomplish this through optimizing existing battery technology and designing the battery layouts in planes so that they become more efficient and effective for long distance travel.

Solar Impulse, the same company that flew 26,000 miles (40,000 km) without one drop of fuel, has just recently been on record stating their plans to develop and launch a solar-powered satellite that would provide affordable accessibility for Wi-Fi and GSM connections to the masses by leveraging the solar and battery tech in their plane.

In a new report released by SolarCity, we are seeing that solar power systems have a usable lifetime of at least 35 years – 40% longer than the market expects. The key finding of the report is that power degradation (annual efficiency loss) of solar panels supplied to SolarCity is as much as 35% lower than for a comparable industry-wide selection of non-SolarCity panels, which are typically expected to last for 25 years. SolarCity feels it is the implementation of a stringent and industry-leading “Total Quality Program” that has driven this. expand full story

Last week, Elon Musk announced his plan for Tesla to acquire SolarCity and fold the solar installer’s operations into Tesla’s own business. The offer is still contingent on board approval and shareholder votes at both companies,  but Electrek has now learned that the automaker is going ahead with trademark applications to sell solar products under its ‘Tesla’ brand. expand full story

Tesla’s energy division has had success in winning contracts for significant energy storage projects at educational institutions in California. Last year, we reported on Tesla installing battery packs at 3 high schools in the San Diego County school districts totalling 32 MWh of capacity. The company also signed a similar deal with the Temecula Valley district and last month, we reported on Tesla installing a 4 MWh project at the College of Marin in Marin County.

Now we learn that Tesla Energy won an important 12 MWh Powerpack contract with Cal State University (CSU). expand full story

Since Tesla announced its offer to buy SolarCity, which is still contingent on a vote by the shareholders, Wall Street has turned on the company with analysts issuing notes claiming that there’s little to no value in the deal. Barclays analyst Brian Johnson issued a note saying that he sees “little in the way of synergies and much in the way of cash burn.”

It’s not like Wall Street analysts have the best foresight, Johnson himself is ranked #2,713 out of 3,984 analysts on TipRank with an average return of -0.7%, but they represent the point of view of the financial sector.

As for the point of view from the actual customer offering/product side, a merger between Tesla and SolarCity will certainly open the door for some interesting product integrations and new distribution opportunities. expand full story

Today, Tesla (TSLA) announced that it submitted an offer to acquire SolarCity (SCTY), the leading solar installer in the US. Elon Musk is the largest individual shareholder of both companies. Due to his obvious interest in the deal, which is already being called a bailout by some shareholders, Musk decided to recuse himself from the vote at both companies and leave it to Tesla and SolarCity shareholders to decide on the possible consolidation of ‘Musk Industries’. expand full story

Yesterday, reported that Apple Inc has founded a new, fully owned, subsidiary known as Apple Energy and that this entity had applied to the Federal Energy Regulatory Commission (FERC regulates power companies) to be able to sell electricity and other power grid services to anyone that is not a public utility. Does this mean that you can now buy clean electricity made on the roof of the Apple Spaceship? Unless you are a large corporate electricity user within 10-30 miles, probably not. However if we step back and take a broader view, something interesting is happening – the likes of Apple, Google, Ikea and others including even Walmart are showing us a small piece of the future of much smarter electricity grid owned by many instead of the few.

Tuesday, SolarCity produced greater than 10GWh of solar electricity via its customer base. This doubles the 5GWh peak in 2015 and more than triples the 3GWh in 2014. SolarCity has over 280,000 customers and greater than 2.16GW installed as of the end of the first quarter – that volume is expected to grow 218MW in the second quarter and to be greater than 3GW before the end of 2016. The summer day peaks around June 20 – meaning we’ll probably see more records broken. expand full story

Much has been made about the coming SmartHome – it started with the Jetsons and their robots, however the reality has been a bit slow coming. Last week, EnergySage+WiseAir+Schneider launched an offer of $300 cash back if you install solar power and a smart thermostat. Back in February, SolarCity+Nest+Tesla introduced the “Smart Energy Home” that combines solar panels, battery storage, smart electric water heaters and the Nest Learning Thermostat. Vermont utilities are renting PowerWalls. It has become clear the home energy generation & management is on the path into powering the SmartHome.
