Most homeowners spend between $12,600 and $33,376 to install a complete residential solar system in 2026, with the national average at $19,873 before incentives. Your actual cost depends on your home's energy needs, roof characteristics, location and other factors, all of which we'll break down in this guide.
These costs are for a typical 7 kW residential system ($19,873 average). Monocrystalline or polycrystalline panels are the most common types of solar panels. Most residential installations use monocrystalline photovoltaics (PV) panels, which offer up to 24% efficiency and perform better in limited space and extreme temperatures.
Monocrystalline solar panels are the most popular choice for residential installation (nearly all residential solar panels installed in 2022 were monocrystalline) because they have the highest efficiency rates from 17% to 22%. The average cost for these panels is between $1 and $1.50 per watt, but prices may differ depending on location.

By the most basic definition, they store energy for later use. While a simple concept, the execution can lean toward the complex. AZE's All-in-One Energy Storage Cabinet is a cutting-edge, pre-assembled, and plug-and-play solution designed to simplify energy storage deployment while maximizing efficiency and reliability.
Imagine an outdoor cupboard that houses all the elements needed for storing renewable energy, neatly packed in one easy-to-manage unit. That's exactly what an outdoor all-in-One energy storage cabinet is. Neat, right? Think of them as your personal mini power station. They store surplus energy and make it available whenever you need it.
Building a BESS (Battery Energy Storage System) All-in-One Cabinet involves a multi-step process that requires technical expertise in electrical systems, battery management, thermal management, and safety protocols.
Discover AZE's advanced All-in-One Energy Storage Cabinet and BESS Cabinets – modular, scalable, and safe energy storage solutions. Featuring lithium-ion batteries, integrated thermal management, and smart BMS technology, these cabinets are perfect for grid-tied, off-grid, and microgrid applications.
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.
Figure 9. Q1 2022 U.S. benchmark: 7.9-kWdc residential PV system cost (2021 USD/Wdc) This section describes our commercial PV model's structure and parameters in intrinsic units (Section 6.1) as well as its output (Section 6.2).
In the longer term, analysts expect the new rules to constrain PV-only deployment in California and ultimately spur the deployment of PV-plus-storage systems, which have higher upfront costs (Wood Mackenzie and SEIA 2022b). Our interviews also indicated market and policy trends affecting system costs between Q1 2022 and Q1 2023.
Benchmark PV operations and maintenance (O&M) costs are estimated using a model (Walker et al. 2020) that provides a line-item cost estimate of measures that correspond to the PV O&M services described in Best Practices for Operation and Maintenance of Photovoltaic and Energy Storage Systems, 3rd Edition (NREL et al. 2018).
