SolarCity Aiming To Produce Solar Modules With +20% Conversion Efficiency At 50¢/Watt

Originally published on Solar Love.

SolarCity’s goals for the Silevo solar module manufacturing facility under development in Buffalo, New York, are certainly not unambitious ones — based on the company’s recent SEC filing detailing the achievements needed via its performance-based compensation plan to vest tranches of shares.

Amongst these achievements, is the meeting of production costs of just 50¢/watt for solar modules with a +20% conversion efficiency — so, as stated above, the company certainly isn’t aiming low.

SolarCity Silevo Efficiency

Considering the scale of the facility, the target doesn’t sound that strange — the manufacturing facility will, after all, be one of the largest of its type in the world once completed. Altogether, SolarCity is aiming for an annual production output of 1 gigawatt of solar modules (1,000 megawatts).

If the 50¢/watt goal is met, the facility will then be in a highly competitive position with Chinese-produced solar modules — potentially making for some very interesting market happenings. When that will occur is currently unknown, though. The facility is expected to come online in 2016, but the ramp-up period is vague.

Worth a reminder here, as well, is that the solar modules produced by the facility are expected to be high enough in conversion efficiency (over 20% to 24%) that fewer modules will be needed for solar arrays or rooftop systems, thereby reducing space requirements, and presumably installation costs.


Electrek provides more:

20% efficiency would be great, but the company aims to eventually hit 24% with Silevo’s Triex technology. They think they could reduce the number of panels per installation by 25%. The breakthroughs would allow for 340 watt panels the size of current 250 watt high-efficiency panels.

These module cost improvements would help the co-founders achieve other milestones of their compensation plan, including the reduction of the total cost per watt, which was at $2.91 last quarter. According to the SEC filing, to vest the last tranche of their compensation plan, they would need to achieve a total cost of installation of $2.05 per watt. This could make residential solar energy more affordable than ever before.

Here are the achievements outlined in the recent SEC filing:

  1. Cost of Production of $0.50/Watt of solar modules with at least 20% efficiency
  2. 1 million Customers
  3. 3 million Customers
  4. 2,000 Cumulative Megawatts Installed
  5. 6,000 Cumulative Megawatts Installed
  6. PowerCo Available Cash of $170 million for Trailing Twelve Months
  7. PowerCo Available Cash of $600 million for Trailing Twelve Months
  8. Average Total Cost Per Watt of $2.75 as of the end of a fiscal quarter
  9. Average Total Cost Per Watt of $2.35 as of the end of a fiscal quarter
  10. Average Total Cost Per Watt of $2.05 as of the end of a fiscal quarter
I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it! We just don't like paywalls, and so we've decided to ditch ours. Unfortunately, the media business is still a tough, cut-throat business with tiny margins. It's a never-ending Olympic challenge to stay above water or even perhaps — gasp — grow. So ...
