Solar generation reaches new high
The IEA expects global PV module generation to increase by 1,800 TWh per year between 2025 and 2027, causing solar to become the second-largest renewable energy source after
28kW solar power systems are mostly suitable for SMEs with medium energy needs. This size of solar power system is classed as "Commercial". A 28kW solar system will certainly cost a different amount depending on the solar business you buy it from. Prices also vary from city to city due to logistics, taxes etc.
The cost of 28kW solar power systems varies. On the lower end, you might expect to get Chinese inverters such as Sungrow, Growatt, JFY, Goodwe etc. and Chinese (lower-tier) panels such as Hannover, Munsterland, ZN Shine etc. You might expect to pay$32,200.00 for such a system.
This is because as panels get large (in Watts) they also become a little bit more efficient. A 28kW system using 370W panels will require about133.3 square meters of roof to be installed. Each 370W panel measures about 1.75m x 1m. 28kW solar power systems are mostly suitable for SMEs with medium energy needs.
Electricity generation by the U.S. electric power sector totaled about 4,260 billion kilowatthours (BkWh) in 2025. In our latest Short-Term Energy Outlook (STEO), we expect U.S. electricity generation will grow by 1.1% in 2026 and by 2.6% in 2027, when it reaches an annual total of 4,423 BkWh.
