Standard test conditions include a solar irradiance of 1,000W per m² and a cell temperature of 25°C, and is the way manufacturers measure a solar panel''s output. The electricity generated by a 5kW system in the UK can still save you hundreds of pounds per year, but you won''t produce much beyond 5,000kWh per year, even in the sunniest regions.
The physical size of the solar panel can impact its power generation, too. Solar panels are made up of solar cells. Most residential solar panels have between 60 and 66 cells, while most commercial panels have at least 72 cells. 72-cell panels have more cells, so there is more surface area to turn sunlight into electricity.

The important thing to remember is that W (watts) is the instantaneous measure of power (it will constantly fluctuate as the sun moves through the sky and passes behind clouds, etc), while Wh (watt-hours, or kilowatt-hours) is the measure of the total electrical energy produced across a period of time–for example, 1 day.
The nominal power (kWp) is the power of the PV system under standardized conditions (solar irradiation of 1,000 watts per square meter at a temperature of 25 °C). This is measured in kWp (kilowatt peak). So here a …

To figure out how much solar power you''ll receive, you need to calculate solar irradiance. This can be calculated using: E = H * r * A. Where: ... For instance, if the inlet temperature is 75°C, ambient temperature is 25°C, solar radiation is 1000 W/m², and the collector area is 2m²: η = (75 - 25) / (1000 * 2) = 0.025 or 2.5%
It is important to realise that sensors in general will measure a temperature between air temperature and panel temperature. Badly designed and badly installed sensors will measure a temperature that is too low. PV panels have temperature coefficients in the order of – 0.4 %/K; at lower a temperature we expect PV panels to perform better.
