![]() Aurora has allowed us to bridge that gap. When sales and operations are aligned, that ultimately allows us to sell more. When you’re selling as much as we’re selling, you have to be able to deliver build-ready projects to your operations team. The 3D models, sunpath, LIDAR, and other tools are very effective in a sale.Įxecutive Director of Sales, Semper Solaris The final product that we’re presenting to the homeowner is just so much more professional. Training & Development Manager, Semper Solaris Our team has already saved a ton of time with this service. Submitting the plan set was as smooth as can be and we had no issues with the AHJ. Project Engineer, Wellspring Components LLC The following reading will introduce the main principles of the design of very large PV systems.Interviews with installers using Aurora’s 3D modeling with shade and tilt analysis during the sales process found that its implementation resulted in as much as a 99 percent reduction in change orders. Engineering decisions require significant technical expertise and should be "informed" decisions based on both optimization models and practical experience. ![]() With many available choices of components and options for optimizing performance, it is important to strike a balance between cost savings and quality. The design of a utility scale PV plant is a complex endeavor. Further optimization of plant design would deal with such issues as shading, performance degradation, and economic trade-offs between increased complexity and energy yield. Key design features include such technical information as PV module type, tilting angle, mounting and tracking systems, module arrangement, and balance of system (BOS) components - inverters, connections, switches, and storage solutions. The feasibility stage also includes site measurements, topography mapping, environmental setting assessment, and social impacts. Then, the plant design is further improved taking into consideration other local limitations and constraints. Initially, the PV plant design is developed at the stage of feasibility assessment which includes estimation of solar resource and expected yield. This presents a great opportunity for emerging economies to effectively meet their growing energy demands, especially since many of those countries possess an excellent solar resource. One of the attractive factors of the utility PV plants is that those facilities can be built relatively quickly (within 6-12 months) due to modular structure, unlike major hydroelectric, geothermal, or fossil fuel facilities, which would be typically developed over 3-5 year span. ![]() The list of the world's largest PV plants is updated from year to year, and you can see that Topaz benchmark has been already beaten repeatedly now, and the top facilities currently exceed GW limit. This facility has the capacity to generate 550 megawatts (MW) of solar electricity using 5 million panels.Ĭredit: Pacific Southwest Region via Wikimedia The Topaz Solar Farm, located in San Luis Obispo County, California, is one of the largest solar photovoltaic power plant in the U.S. Industry experts predict that the trend will hold and perhaps even accelerate into the future as the demand for renewable energy resources escalates. The average and maximum size of the utility solar plants (typically 5 MW to 500 MW) increases as well. The trend really picked up after 2007, when the number of the more than 1 MW systems grew from 20 to over 100 within a few years. Since 2000, installation of MW-scale PV systems has been initiated in Germany, Spain, Italy, Greece, and further taken into even larger scale in U.S., China, India, and Brazil. Architecture of the large-scale PV systemsĭevelopment of large solar PV plants has been underway in a number of countries, especially where the government-backed incentives and legislation were in place to support renewables.
