SunPower ready to build 25 megawatt solar farm in Modesto (McHenry Solar Farm)

Building a solar electric power production plant is more than ordering panels from a panel manufacturer.  There is a whole lotta equipment required such as the frames to hold the solar panels, wiring, power distribution panels, monitoring equipment, monitoring software, training and support, installation, etc.  SunPower has developed a pre-packaged product, the "SunPower Oasis power plant", to provide all the components required to build solar electric power plants from 1.5MW to over 500MW in capacity.

A new project by SunPower in Modesto gives us a look at how this works.

The Oasis product is sold in "1.5 MW power blocks".  The customer then buys enough of these blocks to fill the area they have available, connect them up to the electric grid, and profit.  It sounds a bit like pouring Lego bricks out on the floor and building something out of them, but I'm sure it takes a bit more time.

Each power block includes these components

  • "Tracker" and "Solar panel":- This is solar panels held in a frame, held above the ground on posts, and able to tilt to follow the Sun as it rises in the morning passes overhead and sets in the evening.  Hence the panels must be installed on a north-south arrangement to follow the Sun as it passes from east to west.
  • "Smart Inverter":- Provides "grid interoperability" to massage electricity from the panels, sending it into the grid at the voltage required by the grid.
  • "DC Electrical distribution equipment":- The wires and junction boxes to bring power from the panels, to the inverter, and to the grid.
  • "Tracker Monitoring and Control System" and SCADA:- Hardware and software to monitor the system.

The McHenry Solar Farm is owned by the Modesto Irrigation District.  It's a 154 acre site in an agricultural area in the Central Valley south of Sacramento.  The MID will also build an electrical switching station adjacent to the solar farm.

Hence, this appears to be an example of converting farm land to industrial use.  One wonders whether that's a good idea, or whether we should be focusing on building solar electric production facilities on land that's already industrialized.

SunPower's 25-Megawatt McHenry Solar Farm Poised for Construction Start

Project to Create up to 144 Jobs and Inject $18.7 Million into Local Economy During Construction

SAN JOSE, Calif., Oct. 5, 2011 /PRNewswire-FirstCall/ -- SunPower Corp. (NASDAQ: SPWRA, SPWRB) today announced it expects to start construction on the 25-megawatt McHenry Solar Farm in Modesto, Calif. before the end of the year. The solar photovoltaic (PV) power project received unanimous approval by the Stanislaus County planning commission on September 15, 2011. During construction, it is expected to create up to 144 construction jobs and inject approximately $18.7 million into the local economy. Construction of the facility is contingent on the receipt of all remaining building permits, and is expected to be completed and operational by the second half of 2012.

Electricity produced by the solar PV project will serve the utility grid operated by Modesto Irrigation District (MID), helping the agency achieve California's 33 percent renewable portfolio standard.

"Solar power adds to the diversity of MID's power mix and is an excellent fit for our customers' energy needs," said MID Assistant General Manager of Electric Resources Roger VanHoy. "We have been impressed by SunPower's professionalism and knowledge to date, and are confident SunPower has the experience and technology to cost-effectively deliver a system that will reliably generate solar power for MID's customers for the next 25 years."

The plant will use the SunPower Oasis(TM) Power Plant product, a fully integrated, modular solar power block that is engineered to rapidly and cost-effectively deploy utility-scale solar projects while minimizing land use impacts. Each power block integrates the SunPower® T0 Tracker with SunPower's high-efficiency, E19 solar panel, pre-manufactured system cabling, the Oasis smart inverter, and the Oasis operating system. SunPower Oasis also features the SunPower advanced Tracker Monitoring and Control System (TMAC(TM)) for wireless control of the power plant. The power block kits are shipped pre-assembled to the job site for rapid field installation, and offer the highest capacity factor and the most reliable long-term performance.

"SunPower technology is fast to install, offers guaranteed performance, and is a competitively-priced choice for power," said Howard Wenger, president of SunPower's utility and power plant business group. "We commend MID for seizing the opportunity to help meet the state's growing energy demand and renewable energy goals."
