Optimizing PV Operations & Maintenance Crucial to Reducing LCOE in the US - PV Insider

The solar PV industry in the United States is expected to install 2.86GW of photovoltaic systems by the end of 2012. As the project pipeline continues to grow, and as more plants come online, experts predict that operations and maintenance will play an increasing role in reducing the Levelized Cost of Energy for utility scale systems.

London, UK September 28, 2012

Successfully operating PV plants and maximizing each facility's energy yield over their 20 year+ lifespan is vital if developers are going to deliver on projected output as part of their Power Purchase Agreement. In today's climate plant owners are focused on maximizing the return on investment, including assets such as facilities and O&M staff.

Once commissioned large scale plants require a stringent regime of continued monitoring, scheduled inspection and preventive maintenance. Consequently, developing an effective O&M strategy must incorporate a number of different elements, all aimed at reducing costs, while improving availability and increasing productivity.

In a recent interview with PV Insider Jennifer Granata, the PV reliability lead at Sandia National Laboratories, emphasized the importance of optimizing long term operations and maintenance, stating that "effective O&M strategies maintain a plant's uptime, improve the use of inventory, and optimize labor", all of which "certainly impacts the owner's bottom line".
Granata went on to highlight that "finding problems in the field before they become major issues, such as replacing inverter fans before the inverter derates or completely shuts down, can improve overall plant performance by reducing the downtime and maintaining more predictable plant performance".

Operations and maintenance cost concerns are now a top priority for asset owners in the United States, and based on the positive experiences gained in O&M, as more and more systems come online, experts believe that streamlining O&M will prove vital to reducing costs, and ultimately reaching grid parity.

This is why experts will meet in San Jose on 16 October at the 2nd Operations and Maintenance Training Workshop, to share their wealth of experience with operational plant data on a variety of issues. It was confirmed by PV Insider that participants from NRG Energy, SunPower, Black & Veatch, Sandia National Laboratories and Draker are set to discuss the very latest in pre-construction and plant design considerations for O&M, corrective and reactive maintenance techniques, energy and capacity forecasting, and effective plant monitoring to help the industry move forward in reducing on-going costs in the US.

Featured Product



You haven't installed a tile mount that is easier to install than the Solar Tile Mount manufactured by TRA Snow and Sun. Solar Tile Mount is used on all tile roof profiles: flat, mid, and high. It is made in the USA of aluminum alloy for strength and excellent corrosion resistance. Solar Tile Mount is built to allow more ease in installation with more rise from the tile surface to the rail for better air flow below panels. The adjustable base is longer than most allowing attachment 6" to the left or right to have the bracket in the base of the pan of the tile and still fasten to the rafter. Solar Tile Mount is adjustable for counter batten systems from ¾" to 3". The horizontal rail is directly above base fasteners giving greater uplift resistance than any other system. For superior waterproofing apply TRA Snow and Sun's butyl backed VersaFlash aluminum flashing. No tile flashing is needed on top of the tile for greater labor and material cost savings.
