How much does a solar panel cost per m2?

Global cost per m² in 2025 varied immensely across regions because of labor, logistics, and policy support. In the United States, a typical solar panel cost per square meter in residential installations is between $280–$320 per m² because labor and permission expenses are higher.

How much does a 30m2 solar PV system cost?

A residential property in an urban region of South Africa installs a 30m² solar PV system featuring mid-range monocrystalline panels. The solar panel cost per square meter, including all labor and system components, is approximately $6,000.

What is solar energy per square meter?

Solar energy per square meter is the quantity of sunlight energy (or irradiance) that reaches a one square meter surface region over a specific time period. It is generally measured in watts per square meter (W/m²), and there are variations across several factors like the geographical site, time of the year, and local weather situations.

How much does a solar panel cost per watt?

Let’s use a polycrystalline panel as an example. An average polycrystalline panel offers 160 watts per m2 for $140. Thus, the cost per watt for that panel is $0.87. A high-efficiency PERC panel may offer 200 watts for an area of $180, thus accounting for about $0.90 per watt.

How much does a 400W Tier 1 solar panel cost?

A 400W Tier-1 panel is ¥320-¥520 ($45-$75) in China vs $200-$350 in the US. China produces 80% of global solar panels. Massive factories reduce unit costs. Local polysilicon production cuts supply chain expenses.

How much does a polycrystalline panel cost per watt?

Although the cost per square meter is typically used by engineers or system designers, buyers use the cost per watt to understand the investment costs. Let’s use a polycrystalline panel as an example. An average polycrystalline panel offers 160 watts per m2 for $140. Thus, the cost per watt for that panel is $0.87.
