Solarcity which is the largest US Solar Installer has got sued by Sunpower for stealing trade secrets. Note Sunpower which was recently bought by French Oil Giant Total is facing tough times. Sunpower which makes the most efficient solar panels in the world is facing tough competition from super cheap Chinese solar panels. In fact according to Total CEO the company would have been already bankrupt with Total support. Beside making solar panels, Sunpower is also one of the biggest solar integrators and developers. The company has been in the business of installing solar panels after it acquired solar system intstaller Powerlight.

Sunpower another of the biggest solar companies in the world too is surviving due to its big parent Total.Note the CEO of Total was candid enough to say that Sunpower would be facing Chapter 11 without its support.Total just increased stake in Sunpower as the company continues to make losses.Sunpower has a high cost structure which in these times means you are dead .Even the most cost efficient companies in the West like First Solar faces survival questions.Sunpower with its high cost and high efficiency solar panels would have been dead by now.Note Sunpower too has a bad balance sheet,contorted accounting (already faced a scandal).In fact there are similarities between Sunpower and LDK.

Solarcity has been the fastest growing solar installer in the USA rapidly expanding across the US geography entering new states. Now the company faces charges that former Sunpower employees stole confidential data and gave it to Solarcity.The lawsuit alleges top former officials like Tom Leyden, a Managing Director for the company’s East Operations  of  stealing highly confidential data from the company’s SalesForce database with information on the company’s major customers accounting for over $100 million in sales for 2011 .SunPower is holding five former employees criminally liable under California Penal Code § 502(c)

Silicon Valley-based solar panel giant SunPower sued five former employees and competitor SolarCity today, contending that shortly before they left SunPower, the employees connected USB drives to the company’s computer network, “and used them to steal tens-of-thousands of computer files” with confidential and non-confidential proprietary information.

In addition to civil damages and injunctive relief, SunPower also wants to hold the ex-employees criminally liable for violating a California lawprohibiting unauthorized computer data access and fraud.
