How much does it cost to install solar panels?

According to our solar experts, solar panels cost about $19,000 to install in the United States, on average. While the price tag seems steep, incentives and payment options help make the cost of going solar easier to manage. The total cost of a solar installation depends on your location, energy usage, and even the type of equipment you use!

Do ground-mounted solar panels cost more?

Generally, ground-mounted solar panels will cost more to install than an equally sized roof-mounted system. This is partly due to the structure on which the solar panels are installed. A rooftop system is supported by the roof, and the building’s structure, meaning erecting a supporting structure is unnecessary.

How much does a solar module cost?

Although modules on average mean 30% of total installation costs (USD 357.9/kW), in some countries these prices might be quite different. In South Africa for instance, on average these costs may reach up to USD 557/kW which would account to 42.2% of total plant costs.

What financing options do solar installers have?

You’ll see four major financing options when dealing with a solar installer: cash purchases, solar loans, solar leases, and Power Purchase Agreements (PPAs). With a cash purchase, you’ll pay for everything right off the bat.

How are rooftop and ground-mounted PV systems modeled?

Both the rooftop and the ground-mounted PV systems are modeled with three-phase string inverters with an ILR of 1.23. Both use 20.3%-efficient monocrystalline silicon modules from a Tier 1 supplier (CA NEM 2022). Figure 10 is a schematic of our commercial-scale system cost model, and Table 5 details the modeled parameters in intrinsic units.

Do small-scale installers in the residential sector have a larger PV system?

We infer the predominance of small-scale installers in the residential sector using data on residential system financing (Wood Mackenzie 2022b). The higher efficiency of modules assumed for Q1 2022 (CA NEM 2022) results in larger residential PV system sizes compared with systems in Q1 2021.
