Standaard Thuisbatterij: Powerwall 2 van Tesla domineert de markt

Toch minstens die van USA...

A recently-published report from EnergySage, an online comparison-shopping marketplace for rooftop solar and energy storage systems, has revealed something quite incredible. Despite Tesla Energy’s understated ramp, the Powerwall 2 has actually been dominating the United States’ residential battery storage market — and the competition is not even close.

Tesla Energy’s domination is due in no small part to the Powerwall 2’s pricing, which makes it the least expensive storage option on a per-kWh stored basis.

The findings about Tesla’s humble residential battery unit were shared by EnergySage in its eleventh semiannual Solar Marketplace Intel Report, which covers the 12-month period from July 2019 to June 2020. This time around, the company decided to look into transaction-level battery storage data from its Solar Marketplace. These included information about energy storage solutions that are usually being quoted to homeowners.

Based on EnergySage’s report, over half of the battery storage quotes in the platform included a Tesla Powerwall. This made Tesla’s humble residential battery unit the most-quoted battery storage option in the platform by a wide margin.

As noted in a report from PV Magazine USA, part of the reason behind the Powerwall 2’s domination of the energy storage segment is Tesla’s aggressive pricing, which undercuts competitors to a significant degree. On a cost per kWh stored basis, Tesla offers the cheapest battery storage option in EnergySage’s Marketplace, with its strongest competitor, LG Chem, offering alternatives that are over 30% more expensive. Other competitors are far more disadvantaged against the Powerwall 2 on a cost per kWh basis.

“To date, the two most widely quoted storage brands on the EnergySage Marketplace are Tesla and LG Chem, in line with installation data from California’s Self Generation Incentive Program (SGIP) over the last few years. Presently, over half of all quotes on EnergySage are for the Tesla Powerwall 2. Looking at installed costs, Tesla is also the lowest cost offering on a dollar per kilowatt-hour ($/kWh) basis. Interestingly, two companies who use lithium iron phosphate (LFP) battery chemistries–Enphase and sonnen–see the highest $/kWh costs in the Marketplace,” the report noted.

The Powerwall 2 may be Tesla’s most humble battery storage unit, but it holds a lot of potential. Boasting an integrated DC/AC converter, off-grid capabilities, and mobile app support, the Powerwall 2 has all the elements of a classic Tesla product. The battery unit, just like the company’s electric cars, receives over-the-air updates, optimizing its performance and adding new features. Among these is Storm Watch, which maximizes energy storage during inclement weather and other conditions that may threaten the power grid.

EnergySage reports on storage for the first time ever, Tesla dominates

In the newest edition of EnergySage’s Solar Marketplace Intel Report, data about energy storage solutions being quoted to homeowners through the platform has been included for the first time — with more than half of the quotes for Tesla’s Powerwall 2.

Tesla Solar Roof Installation Time Lapse: 40 Squares In 4 Days by Weddle and Sons Roofing!

Weddle And Sons Roofing vor 6 Stunden

Few good questions already that we'll answer here for visibility:

1) Weather was good--how does it work when there is rain during the install?

Once the Firestone underlayment is installed, the roof is 100% watertight. On this job, tearoff and underlayment was done in one day. We actually got heavy rains over the weekend after that first day and had no issues. Then going forward, the roof stays watertight throughout installation, it just is difficult to work on the roof when wet. A couple of nights we covered small sections with plastic so we could start early the next day without the moisture from overnight dew.

2) How does installation time compare to a conventional roof?

A standard shingle roof this size with one of our best crews would be 1-2 days. This was 5 days with a full team, plus some individual trips for material unloading, cleanup, misc. loose ends, etc. It's probably comparable in time to what a standing seam metal roof would take. We're still very early in the ramp-up process though, and we are working on lots of ideas for speeding up installation.

3) Can we post more about production and utility bill impact?

Yes, we will try to get to that after we have more data (and with some clients' permission). It probably won't happen for a couple months though (sorry). We'll try to at least cover more of the inverter/powerwall side of things soon.
