A Solar PV Balance-of-System or BOS refers to the components and equipment that move DC energy produced by solar panels through the conversion system which in turn produces AC electricity. Most often, BOS refers to all components of a PV system other than the modules.
Using the NREL''s modeled market price, a 7.9 kW solar system would cost $23,305 and solar panel installation labor cost would account for just $1,264. So, while homeowners are used to labor being a notably expensive part of car repairs, landscaping, and other home improvement projects, it''s a relatively small piece of the puzzle for solar

However, what is interesting to see is that these cost reductions were led by hardware components, with modules and inverters accounting for 62% of the global weighted-average total installed cost decline between 2010 and 2019. Balance of systems costs costs are therefore an important contributor to the declining global weighted-average total
Heading into 2024, solar panels can account for about 13% of the total project cost, while inverters and balance of system (BOS) equipment account for 33% of the total cost of an average project. The majority of the project cost goes toward soft costs, including labor, permitting, overhead, and profit, which we''ll explore below.

2. Evolution of Residential Solar PV System Costs (2009-2017) Since 2009, the cost of solar panels has decreased by a whopping 60%. Combined with the 30% federal tax credit, this reduction in overall installation costs has been a major catalyst for the growth of the solar industry. Intense competition and economies of scale in the solar hardware market led to plummeting
While the upfront cost of solar panels may seem manageable, it''s important for consumers to understand that a complete solar power solution involves an entire ecosystem of components and considerations. What is Balance of Systems (BOS)? Balance of Systems refers to all the components of a solar power system other than the solar panels themselves.
The cost of the balance of system includes the cost of inverters, hardware, labor, sales tax, and overheads. It also covers permitting interconnection and inspection (PII) fees, land cost, buildings cost, and any other expenses that may apply. Like solar modules, the total cost of the balance of system has declined over time.
There are many factors that go into the cost of a solar PV system. Learn more about them, and how to explain them to customers. including modules, inverters, balance of system (BoS) components, optional batteries, Cost breakdown of PV systems. Source: B. Fiedman, et al, "Benchmarking Non-hardware BoS Costs for US PV Systems, Using a

A Comprehensive Look at BoS Costs and Energy Production in a Typical Commercial 208V Grade Application In the competitive solar landscape, optimizing the Balance of System (BoS) costs is crucial. BoS includes all solar system components—inverters, mounting systems, cabling, electrical elements, conduit, and installation labor.
For residential and small-scale systems, the BOS and installation costs comprise 55% to 60% of total PV system costs. The average cost of BOS and installation for PV systems is in the range of USD 1.6 to USD 1.85/W, depending on whether the PV system is ground-mounted or rooftop, and whether it has a tracking system (Bony, 2010 and Photon, 2011).
The cost of the electricity generated by a PV system is determined by the capital cost (CAPEX), the discount rate, the variable costs (OPEX), the level of solar irradiation and the eficiency of the solar cells.
