The announcement of Tesla’s solar products caught the media off guard, instantly capturing our attention with their draw-dropping beauty and simplicity. We held a collective breath—how much are these going to cost, exactly? Are they scalable? Endless Energy The sun is a free and relatively endless source of energy. The Tesla website reminds us that, “The sun provides more than enough energy in just one hour to supply our planet’s energy needs for an entire year.” Harnessing that power simply makes sense. To help consumers utilize that power, Tesla finalized the acquisition of SolarCity for roughly $2.6 billion in November 2016. Together, the entities aim to  “provide customers with full-stack solutions for owning their own energy production, storage and consumption.” To date, that stack includes solar tiles, Powerwalls and Powerpacks. Solar Tiles Tesla solar tiles create stunning, energy efficient roofs that are also affordable. Fortune estimates the solar cell costs to be $0.40 per watt, comparable to commodity solar panels. The difference comes in their efficiency: Tesla’s solar tiles are nearly 15 percent more efficient. The solar roofs can also be less expensive. Tesla CEO Elon Musk states that he aimed for an installed cost that is less than the cost of a conventional roof and the electricity bill for a home. Some of the cost savings come in the form of shipping. Tesla’s tiles are one-fifth the weight of similar products. That makes the lightweight and ultra durable material easier and less expensive to transport. They are also harder to break than asphalt shingles or terra cotta tiles, reducing the cost of wasted materials. The durable tiles will not need to be replaced or repaired as often as conventional roofing or competitors’ solar panels. Where traditional roofing shattered under impact, the Tesla glass...

Sports cars are beginning a new historical chapter with amazing Porsche focused on delivering their first 100 percent electrically powered car by the end of the decade. Many insist that the all-electric sedan is out for Tesla blood, and what’s clear is that the future of the sports car looks electrifying. It’s a big thing, the Mission E project; in Stuttgart-Zuffenhausen alone more that 1,000 new jobs are being created and the company announced it will be investing around 700 million euros in its main site there. Over the next few years, the company will build a new paint shop and a new assembly plant. The existing engine factory will also be expanded for the production of electric motors and the existing body shop is being enlarged. Porsche originally revealed the Mission E as a concept car at the International Motor Show in Frankfurt last September. At the time, the company revealed that it would have a range of 300 miles and include a number of innovative technologies. The high-tech features that will be included in the production model have not yet been revealed, but the Mission E concept that was presented last year kind of gives us an idea of what to expect in the final product. The four-door car with four individual seats has a system power of over 600 horsepower (440kW), which enables the vehicle to achieve acceleration of 0 to 62 miles per hour in just 3.5 seconds, behind Tesla’s Model S which can go from zero to 60 in 2.8 seconds with a Ludicrous Mode upgrade—the name represents an upgraded battery pack, from 85 to 90 kWh, which Tesla says is good for an extra 15 miles of range. Mission E is completely powered by advanced lithium-ion battery technology....

Institutions and regular citizens are transitioning from a fossil-fueled past to a cleaner energy future. The cost of installation for such systems has dropped considerably in recent years, making them more affordable for general use. Currently, one of the biggest wrinkles in this still young industry is storage. A study by EuPD Research shows that just 34 percent of photovoltaic installers in the U.S. offer storage solutions to customers. The company’s latest PV Installer Survey revealed that current pricing of batteries impedes demand, meaning margins are too low for installers and the “technological maturity” of the systems on the market is not currently convincing. But things are gradually changing—26 percent of survey participants say they are working on adding storage products sometime this year. However, across all sectors there is a growing trend for more storage globally—IHS forecasts as much as 900 MW of storage projects will come online in 2016, meaning a doubling of the current cumulative installed storage capacity globally. GTM found that in the U.S., the storage market more than tripled in 2015, growing 241 percent for the year, spurred by pro-storage policies in many solar states, as well as incremental price decreases for leading battery technologies like lithium-ion. The leader in the field is  Tesla’s Powerwall; the product scored top marks for “unaided brand awareness” in the EuPD Research survey, as installers discovered they had very little marketing to do to consumers. Another very popular battery brand is Trojan (solar & storage installations), but we want to talk about the new Orison home battery, the product of a San Diego-based startup. Launched on Kickstarter this year, Orison is going up against the biggest names in energy storage, an emerging area of technology of great importance. Orison’s stylish new product has...

It’s been all over the news – the real-life Tony Stark has unveiled Tesla Energy, an ambitious plan to power the world with a home battery which eventually will not only make the consumers less dependent on the grid, but take them off it entirely. Tesla founder Elon Musk has presented the Powerwall. And it makes complete sense. Tesla launched the home battery system and Tesla’s CEO Elon Musk is the chairman at SolarCity; SolarCity will handle the installation of the Powerwall. The Powerwall measures 51.2” x 33.9” x 7.1” and comes in different colors; its primary function is that of storage system for solar power, but will also work for non-solar energy consumers in cases of power outage and furthermore to avoid feeding from outside electricity during peak periods (evenings) when utility prices are highest. Up to 9 devices (totaling 90kilowatt hours) can be stacked per home. It is good to know that the typical American home consumes daily about 30 kWh, so in order to cover the entire power need, one would need several batteries. Additionally, Musk announced that there will also be the Powerpack, a similar device designed with industrial usage in mind, as well as a smaller 7 kWh Powerwall. Here are some specifications on the Powerwall: Models: 10 kWh $3,500 – For backup applications 7 kWh $3,000 – For daily cycle applications Warranty – 10 years Compatibility – Single phase and three phase utility grid compatible. Power – 2.0 kW continuous, 3.3 kW peak Operating Temperature: -4°F to 110°F / -20°C to 43°C Musk’s new baby is already promising to grow big and strong as there is major interest in the product – the company has announced that so far it has taken 38,000 reservations for the home battery, a number that made...
