Lowry's Piccadilly Circus equals artist's 5.6m record at major auction

He is best known for his paintings of matchstick men walking against a  background of bleak northern mill towns.

But one of LS Lowry's few paintings of London became the most expensive of the artist’s work in the world yesterday after it was sold for a record 5.6million.

The 1960 oil painting of London’s bustling Piccadilly Circus, which had not been seen in public for nearly 30 years, was last night sold at Christie’s auction room just a stone's throw from the iconic junction.

It shares the record for the most expensive Lowry piece to be sold, matching the one set by ‘The Football Match’ when it was sold in May.

The artwork, which was part of hotel tycoon Lord Forte’s collection for almost  three decades and has never been auctioned before, was sold to a mystery telephone bidder.

It depicts Piccadilly's famous fountain, topped by the famous statue of Eros amid a throng of red buses and scurrying figures.

The painting shows advertisements for Coca-Cola, Bovril, Max Factor  and Wrigley’s on the famous hoardings overlooking the junction.

It was one of 14 Lowry oil paintings from the late Lord Forte’s collection to be sold for a total of 17.7million last night by his descendants.

The auction house described the selection as ‘undoubtedly the highest quality  group of works by the artist to come to the market’.

Three other paintings were auctioned off for more than a million pounds.
‘Fun Fair at Daisy Nook’ from 1953, which depicts mill workers in Lancashire  celebrating Good Friday, sold for 3.4million and ‘Saturday Afternoon’ from 1941, which shows figures playing football and cycling at the weekend in front of an imposing factory building, went for 2million.

An unnamed 24x36in industrial landscape sold for 2.6million.

Lowry painted only five London scenes, of which two depict Piccadilly Circus.

An earlier painting of the junction dating from 1959 was sold in June 1998 for 562,000, which was at the time a record price for the artist.

But at 20x24in, the artwork was much smaller than the 30x40in painting sold  yesterday.

Although the scene of Piccadilly Circus looks very familiar, much of what is in  the painting has changed in the past five decades.

The area underwent reconstruction in the late 1980s when the fountain at the  centre of the junction was moved to its present location on the south-west corner.

The only company depicted in the painting to be still advertising on the famous  hoardings, is Coca-Cola, which has now taken the place that Bovril takes in the  painting.

Lord Forte, who died in 2007, built up his worldwide leisure empire after opening a milk bar on London's Regent Street in 1935, at the age of 26.

The peer, who died in 2007, had held many of the paintings for decades.
Lowry lived in Greater Manchester, and became famous for painting industrial landscapes peopled by distinctive figures with thin bodies and large heads.

Lowry, who died in 1967, claimed to be a 'simple man' who could not understand  modern art, but is now treated as a major artist, with much of his work exhibited in a purpose-built museum in Salford.

He was a notoriously private man who hated publicity, and was secretive about his job at the Pall Mall Property Company, where he worked for decades to support his artistic career.

The sale comes at a buoyant time for the art market, which is seen as a relatively safe place to invest money during this period of turmoil in other markets.

Enphase Launches Solar IT Offensive

Enphase Energy has been creating a market for solar microinverters –distributed inverters that replace a central inverter for solar panels — since its initial product launch in the summer of 2008 and has now shipped more than 500,000 of them.

To keep its lead will not be easy, however. Not only is venture-backed Enphase facing competition from other microinverter developers, but it's also up against companies making alternative and more mainstream products, like the traditional central inverters. To remain competitive, the Petaluma, Calif., startup will be launching a series of products this year that are smaller, lighter and tailored to different customer types.
Enphase Offensive

In June, it plans to launch its third-generation technology that will boost its microinverter's average efficiency to 96 percent, a one percentage point improvement from the current version, Enphase's VP of products, Raghu Belur, told a group of reporters at the company's headquarters Tuesday. The company will also offer a new installation method that will help shave labor costs. Enphase CEO, Paul Nahi, also hinted at the possibility of offering a warranty that will be longer than the 15 years that it current provides.

In addition, the startup, founded in 2006, is working on a microinverter specifically designed for the larger, commercial installations, Nahi said. Until now, the company has offered the same microinverter for both residential and commercial installations. And, by the end of the year, Enphase is looking at rolling out yet another product that will feature three chips, which will reduce the number of components in its microinverter box and improve its efficiency at power conversion, Nahi said.

The three-chip design will be a departure from the use of a single chip, but Nahi was mum about how the three chips will divide up the core functions of power conversion, communication, control and command. He also declined to talk about the likely efficiency of this new design.
Microinverter Market

Inverters are electronic devices that accompany every solar energy system. They convert the direct current from the solar panels into alternating current for use onsite (at home or business) or for feeding into the grid. Microinverters are so named because they are much smaller than the centralized inverters that dominate the market today. A centralized inverter is larger and sits near the edge of a solar energy system and converts all the electricity flowing from the solar panels.

A microinverter, which is roughly the size of a half-piece of paper, is attached to each solar panel instead. It's a design that enables close monitoring of each solar panel's performance and circumvents the tendency of a solar array to drop its power output collectively even if only a few solar panels aren't able to perform optimally because of, say, shading or debris that blocks the sunlight from hitting the cells inside the panels.

“Our microinverters are generating more power than you would with a centralized inverter. That's just physics,” Nahi said.

Enphase executives say they've carved out a market for a type of technology that couldn't take off before Enphase's arrival, primarily because it was too expensive, inefficient, unreliable and lacked communication functions to effectively monitor performance. The company sells not only the microinverter but also software and services for monitoring the power production of each system. Both installers and system owners can check on the performance of each solar panel by logging into an Enphase portal, and the microinverters will alert them of significant drop in power production.

Microinverters have no shortage of critics, who contend that microinverters haven't proven their staying power because they are new to the market. They also argue that installing a bunch of microinverters could lead to frequent repairs and replacement. Microinverter advocates have countered that the failure of a centralized inverter will cripple the production of an entire solar array, whereas problems with a few microinverters will only handicap the performance of those few solar panels.
Future of Microinverters

Microinverters do remain more expensive than central inverters. Enphase executives say their gears are 15 percent more expensive, but they have come up with installation methods to cut labor costs. A new installation method, to be offered with the third-generation microinverter in June, will involve Enphase-provided cables with built-in connectors and clips to pin the cables to the racks underneath the solar panels. A single bolt will secure each microinverter, which will then plug into the connector on one side and solar panel on the other.

So, that 15-percent price premium will be offset by a lower installation cost and the extra 5-25 percent electricity production, Nahi said. This sales pitch could work well for installers who care more about the amount of energy to be produced over time than the upfront installation cost.

The majority of its microinverters have gone to residential systems. Enphase is keen to expand its reach in the commercial sector, where each installation is larger and therefore requires more microinverters. The company plans to launch a microinverter with a higher voltage to target the commercial sector, Nahi said. The largest project to date that uses Enphase's gear has 750KW of generation capacity, Belur said.
Enphase Wins Converts

The company sells its microinverters and services through distributors and solar panel makers such as Suntech Power, Canadian Solar and Siemens. A major installer who until recently wasn't an Enphase convert will use the microinverters as a result of snapping up businesses that were Enphase customers. That installer is SolarCity, based in San Mateo, Calif., which bought Clean Currents Solar and groSolar's residential installation business recently in order to expand its business to the East Coast, said Jake Whiteley, strategic account manager at Enphase.

Although Enphase is the largest microinverter supplier, it's not the only one and will face a growing competition from fellow microinverter developers. Competitors include SolarBridge Technologies in Texas and Enecsys in the United Kingdom. Its central inverter nemeses include SMA Solar Technology and Power-One.

Transphorm, a Google Venture-backed startup, also is eyeing the solar market with its power conversion technology. Instead of using silicon chips, as Enphase does, Transphorm is using gallium nitride. Enphase also is investigating the use of these more exotic materials, Nahi said, but has no plans to roll out products using them any time soon.
