The analysis of total microgrid costs per megawatt shows that the community microgrid market has the lowest mean, at $2.1 million/MW of DERs installed; followed by the utility and campus markets, which have mean costs of $2.6 million/MW and $3.3 million/MW, respectively. Finally, the commercial market has the highest average cost, at $4 million/MW.
In commercial/industrial and utility microgrids, soft costs (43% and 24%, respectively) represent significant portion of the total costs per megawatt. Finally, energy storage contributes significantly to the total cost of commercial and community microgrids, which have percentages of 25% and 15%, respectively, of the total costs per megawatt.
The U.S. Department of Energy commissioned the National Renewable Energy Laboratory to complete a microgrid cost study and develop a microgrid cost model. The goal is to elucidate the variables that have the highest impact on costs as well as potential areas for cost reduction. This study consists of two phases.
The analysis shows that controller cost data as a percentage of total microgrid costs are relatively similar among the projects in our database and the NY Prize data despite the wide variety of system sizes, types, and uses. Controller costs per megawatt range from $3,500/MW to nearly $600,000/MW, excluding outliers, with a mean of $85,000/MW.
Despite the relative novelty of the microgrid market and the challenges faced when discussing microgrid costs, it is a very useful exercise to collect cost information from the microgrid community and better understand component costs and differences from one project to another. The principal goal in Phase I of the study was to collect data.
In DC microgrid configuration, there isonly one conversion stage between the PV arrays and the DCloads which decreases the power loss, while anAC microgridincludes two conversion stages. In both microgrids, The PVis sized such that the maximum supplied power does notexceed the load demand and is approximately equal to therequired power load.

Solar Air Conditioning Systems: Principles, Benefits, and Costs
Solar Panels: The cost of photovoltaic (PV) panels, which convert sunlight into electricity to power the air conditioning system. Prices vary based on panel efficiency, brand, and installation size. On average, expect to budget between $10,000 to $20,000 for panels in a typical residential setup. Inverters: These devices convert DC electricity produced by solar panels into …
