2. Solar-cell efficiency - Wikipedia

   en.wikipedia.org/wiki/Solar-cell_efficiency

   [1] [2] In a high-yield solar area like central Colorado, which receives annual insolation of 2000 kWh/m 2 /year, [3] a panel can be expected to produce 400 kWh of energy per year. However, in Michigan, which receives only 1400 kWh/m 2 /year, [3] annual energy yield drops to 280 kWh for the same panel. At more northerly European latitudes ...

   After years of cost reduction, the average US price per watt was between $2.51 to $3.31 in 2020 for 10 kW systems, [89] and $1.05/W for utility systems. [90] Another type of distributed generation implemented by a utility company was the world's first grid-connected pole-attached solar panels of Public Service Enterprise Group in New

4. Nominal power (photovoltaic) - Wikipedia

   en.wikipedia.org/wiki/Nominal_power_(photovoltaic)

   The nominal power of PV devices is measured under standard test conditions (STC), specified in standards such as IEC 61215, IEC 61646 and UL 1703. Specifically, the light intensity is 1000 W/m 2, with a spectrum similar to sunlight hitting the Earth's surface at latitude 35°N in the summer (airmass 1.5), the temperature of the cells being 25 °C.
