Department of Energy (DOE) Solar Energy Technologies Office (SETO) and its national laboratory partners analyze cost data for U. solar photovoltaic (PV) systems to develop cost benchmarks. These benchmarks help measure progress towards goals for reducing solar electricity costs and guide SETO research and development programs.
The benchmarks are bottom-up cost estimates of all major inputs to typical PV and energy storage system configurations and installation practices. Bottom-up costs are based on national averages and do not necessarily represent typical costs in all local markets.
The cost of solar panels ranges anywhere from $8,500 to $30,500, with the average 6kW solar system falling around $12,700. It's important to note that these prices are before incentives and tax credits are applied. We found that solar panel prices vary based on where you live, the size of the system, the type of solar panels and more.
The average cost for polycrystalline solar panels ranges from $0.90 to $1.50 per watt. Both polycrystalline and monocrystalline solar panels are photovoltaic (PV) solar panels. They convert sunlight into electricity.
Maintaining your solar panels costs anywhere from $140 to $180 annually or an average of $150 per year if you hire a pro to maintain your solar panels. At this cost, your pro will inspect the panels for signs of repairs.
The MMP results are $30.36 (residential), $40.51 (community solar), and $16.58 (utility-scale). The community solar O&M cost is higher than the O&M cost for a single-customer commercial PV system of similar configuration because of the community solar subscriber management cost, which accounts for about 40% of the total community solar O&M cost.
