About Labor costs for connecting photovoltaic panels to small wires
NREL analyzes the total costs associated with installing photovoltaic (PV) systems for residential rooftop, commercial rooftop, and utility-scale ground-mount systems. This work has grown to include cost models for solar-plus.
U.S. Solar Photovoltaic System and Energy Storage Cost Benchmarks, With Minimum Sustainable Price Analysis: Q1 2023, NREL Technical Report (2023) U.S. Solar Photovoltaic System.
Watch this video tutorial to learn how NREL analysts use a bottom-up methodology to model all system and project development costs.NREL's PV cost benchmarking work uses a bottom-up approach. First, analysts create a set of steps required for system installation. Next, they calculate the hardware, equipment, direct labor, and indirect labor costs associated with each step for a given location and system design.

Based on 2022 average labor rates, solar panel installation cost accounts for roughly 5.5% of the total cost of a solar project, according to the National Renewable Energy Lab (NREL). To put that in perspective, using the a modeled market price (MMP) of $2.95 per Watt for residential solar, labor costs contributed just 16 cents per Watt of .
Mounting and Balance of System: This includes the cost of mounting equipment and other necessary components like wiring, switches, and a meter. Installation and Labor: The cost of professional installation, which can vary based on location, system complexity, and the installer’s rates.
When that happens, the utility or company has to pay labor costs for workers to go out and fix the damage and material costs for a new connector, PV wire, and other BOS parts. The company also loses money because the system isn’t generating as much power, leading to lower profits and potentially unhappy customers.
Labor costs vary from region to region, but total labor costs run about $0.27 per watt and can be 10 to 25 percent of the total system costs. Labor costs include electrician and non-electrician installation labor. For a standard 3 kW system of about 20 solar panels, the average installation time is 75 man-hours, Caldwell said.

6 FAQs about [Labor costs for connecting photovoltaic panels to small wires]
How much do solar panels cost?
The cost of solar panels and installation will vary depending on the company you use, your location, the type of system you choose, installation challenges, and other issues. However, the nationwide average is $20,650. Systems tend to range between $17,430 and $23,780. The three most popular types of solar panels are:
How much does solar installation cost?
According to the NREL data above, installation typically accounts for 5.5% of the total cost of a residential solar project, so this equation will get you a ballpark figure for labor costs. For example, if you receive a solar quote for $25,000, you can expect labor to make up around $1,375 of the all-in cost.
How to wire solar panels together?
Wiring solar panels together can be done with pre-installed wires at the modules, but extending the wiring to the inverter or service panel requires selecting the right wire. For rooftop PV installations, you can use the PV wire, known in Europe as TUV PV Wire or EN 50618 solar cable standard.
How much does a solar project cost?
For example, if you receive a solar quote for $25,000, you can expect labor to make up around $1,375 of the all-in cost. (Check out our solar calculator to estimate the cost of your project.)
How much does a 6kW Solar System cost?
A 6kW system will run between $5400 and $6000. Thin-Film: Thin-film solar panels are made by attaching one or more thin layers of photovoltaic material onto a glass, metal, or plastic substrate. They are the least efficient option. A 6kW system costs between $4200 and $6000. Labor typically costs around 25% of the system itself.
How to add Solar connectors to PV wires?
The steps to add solar connectors to PV wires are the following: Strip the wire. Place the connecting plate on it and use the crimping tool. Insert the lower components of the connector (terminal cover, strain reliever, and compression sleeve). Insert the upper components (safety foil, male/female MC4 connector housing, O-ring).
