Solar PV Balance-of-System Costs to Surpass Modules by 2012, According to GTM Research June 30 2011 - 10:29AM Business Wire As solar PV module prices continue to decline globally, balance-of-system (BOS) components will assume a majority share of a PV project’s total cost per watt within the next year, according to GTM Research. c. Systems that work seamlessly and dependably d. Increase training and development resources. The Most Important Cost in Solar Balance of System costs are becoming more important by the day. Eng. 253 Life cycle costing of PV generation system in the last decade as it shown in Fig 3 [9-10]. Solar photovoltaic (PV) electricity has significant potential to contribute to U.S. energy needs. I would like to include balance of systems in the cost model (like a charge regulator and solar panel rack in the PV module). So, it can be understood that the BOS components consist of majority of the items as needed for a Solar PV Plant and the account for 10-40% of the system cost with Installation & Commissioning. The report focuses specifically on soft costs, i.e., non-hardware costs… This article originally appeared on Lexology, and was written by Charles W. Malcomb | Hodgson Russ LLP. By 2012, a GTM article cited that it had dropped to 32 percent. Without these, the design and installation of solar can be not only complex, but components that are incompatible in the field lead to further cost increases and inefficiencies of labor. BOS applies to all types of solar applications. Although solar photovoltaic electricity has reached grid parity in select markets, the high cost of solar has hampered it from becoming a true game-changer. The price of residential solar power in the United States keeps dropping. Now, they are around 70% of total PV system costs. As the cost of PV modules becomes an increasingly smaller piece of the total solar project cost, balance of system (BoS) cost has become a focal point of efforts to increase feasibility.

The cost structure of any photovoltaic (PV) system comprises mainly two components: (1) the module, which converts sunlight to electricity, and (2) the balance of system (BOS) costs, which is an all-encompassing term representing everything else needed for the solar system to be erected and functional including, inverter(s), mounts, cables, bolts, labor, permitting, grid connection, etc. c. Electrical Components Balance-of-systems cost and efficiency can enable business growth by way of: a. Expansion into new sectors (i.e. The balance of system ( BOS) encompasses all components of a photovoltaic system other than the photovoltaic panels. Efforts have been made to coordinate and focus BoS reduction efforts. In reply to Thanks, Stuart - good by Pete Marsh. d. Interconnectivity / Equipment Compatibility. On average, a solar panel system pays for itself within eight years. BY. Identifying the required approvals and navigating the permitting processes can be time consuming and costly. To receive a Certificate of Public Good, the customer must register the system with the PSB. Balance of System (BoS): Cables, junction boxes, earthing equipment, lightning arrestors and conduits etc. Calculate ways to install a solar system to determine which balance-of-systems components will be optional and which will be necessary. This report provides estimates of baseline balance-of-system (BOS) soft costs for solar photovoltaic (PV) systems installed in New York State in 2016. What does balance-of-system mean? With the right knowledge, a solar PV systems provider can guide consumer interest where state incentives and federal rebates apply to total expenditure, lower costs where rebates and incentives are not applicable, and focus on BOS efficiency within design planning and implementation. Discuss your challenges with our solutions experts . Hardware innovations, volume manufacturing and competition made significant effects on hardware pricing, but now hardware costs are plateaud and a fundamental change is needed to continue that downward pricing trend. Summing Up OPPORTUNITY: Indias National Solar Mission: To set up a capacity of solar power generation of 20000 MW by 2022 Seen as the long term solution to Indias power deficit Total Capital Outlay at Todays Prices for adding 20,000MW Capacity is INR 4 lakh crores (USD 90 Billion)! Life Cycle Costing. The higher BOS cost is needed for standalone systems … Solar Balance-of-System Costs Account for 68% of PV System Pricing: New GTM Report Over the course of the past year, the solar PV balance of … In fact you can account for such costs in HOMER's cost tables. I. Introduction—The Case for PV Balance of System (BoS) Cost Reductions 10 BoS Costs Constitute a Barrier to Widespread Solar PV Adoption 10 Solar Energy Offers a Large Opportunity 10 Widespread Adoption Requires >50% Cost Reductions 10 Balance of System Costs Are an Important Issue 10 6. For example, if the PV array costs $7/W and the PV mounting hardware will cost $500 regardless of the size of the PV array, you can model that scenario as f Res. Contract: DE-SC0011823. 4. Cheaper batteries have made storage more affordable, but declines in balance-of-system costs are set for a much bigger role, Wood Mackenzie says. Solar PV Balance of System | Rocky Mountain Institute | RMI.org This RepoRT Solar photovoltaic (PV) electricity offers enormous potential to contribute to a low-carbon electrical system.
