Products

EPC Construcion Activity


EPC

Sun Roof provides EPC (Engineering, Procurement and Construction). We plan the actual layout of the solar park (Engineering), acquire components and services (Procurement), and build the photovoltaic plants including the necessary infrastructure (Construction). Our engineers optimize the solar plants for any given site. On request we also provide project financing and operational management.

Engineering

  • Preliminary design (basic planning and engineering)
  • Approval design
  • Construction design (detailed engineering)

Procurement

  • Specifications
  • Tendering/bid comparisons
  • Contract preparation
  • Purchase of modules

Construction

We provide a professional project management and controlling strategy during the entire lifespan of each project. Our engineers provide a detailed installation documentation, thus guaranteeing a smoothly coordinated construction and a completion on time. We have a proven network of reliable partners and suppliers with great practical experience. Our services include:

  • Preparation of installation and construction documentation
  • Specialist risk management
  • Specialist site management
  • Logistics co-ordination
  • Safety co-ordination
  • Commissioning and performance testing
  • Experienced project management and detailed documentation

O&M

O&M Approaches and Activities

Maintenance can be broken down in two parts:

  • Scheduled maintenance: Planned in advance and aimed at fault prevention, as well as ensuring that the plant is operated at its optimum level.
  • Unscheduled maintenance: Carried out in response to failures.

Another way to classify the PV O&M approaches is to break them down into three categories, each with different cost-benefit tradeoffs and risk profiles:

  • Preventative maintenance (PM) encompasses routine inspection and servicing of equipment — at frequencies determined by equipment type, environmental conditions, and warranty terms in an O&M services agreement — to prevent breakdowns and unnecessary production losses. Th is approach is becoming increasingly popular because of its perceived ability to lower the probability of unplanned PV system downtime. However, the upfront costs associated with PM programs are moderate and the underlying structure of PM can engender superfluous labor activity if not optimally designed.
  • Corrective or reactive maintenance addresses equipment repair needs and breakdowns after their occurrence and, as such, is instituted to mitigate unplanned downtime. The historical industry standard, this “break-fi x” method allows for low upfront costs, but also brings with it a higher risk of component failure and accompanying higher costs on the backend (perhaps placing a premium on negotiating extended warranty terms). Th ough a certain amount of reactive maintenance will likely be necessary over the course of a plant’s 20-year lifetime, it can be lessened through more proactive PM and condition-based maintenance (CBM) strategies.
  • Condition-based maintenance (CBM) uses real-time data to anticipate failures and prioritize maintenance activities and resources. A rising number of third party integrators and turnkey providers are instituting CBM regimes to offer greater O&M efficiency. The increased effi ciency, however, comes with a high upfront price tag given communication and monitoring software and hardware requirements. Moreover, the relative novelty of CBM can produce maintenance process challenges caused in part by monitoring equipment malfunction and/or erratic data collection.

Preventative Maintenance (PM) includes the following activities:

  • Panel Cleaning
  • Water Drainage
  • Vegetation Management
  • Retro-Commissioning (identifies and solves problems that have developed during the course of the PV system’s life.)
  • Wildlife Prevention
  • Upkeep of Data Acquisition and Monitoring Systems (e.g., electronics, sensors)
  • Upkeep of Power Generation System (e.g., Inverter Servicing, BOS Inspection, Tracker Maintenance)
  • Site maintenance (e.g., security, road/fence repair, environmental compliance, snow removal, etc.).

Corrective/Reactive Maintenance typically includes:

  • On-Site Monitoring
  • Non-Critical Reactive Repair (addresses production degradation issues)
  • Critical Reactive Repair (high priority, addresses production losses issues)
  • Warranty Enforcement

Condition-Based Maintenance (CBM) usually consists in Active Monitoring — Remote and On-Site Options Equipment Replacement (Planned and Unplanned) and Warranty Enforcement (Planned and Unplanned).
