The total amount of electricity the system actually generates in a year is measured in kilowatt hours kWh. A typical domestic Solar roof array system is between 1kWp would typically generate to kWh per year depending on size, keeping tilt angle same as latitude angle.
By contrast an average home uses kWh of electricity per year on lights and appliances. However, an energy efficient home using A rated appliances and lighting could conceivably use half this value. You must be logged in to post a comment.
For any given location, you may have access to a number of weather files. In Figure 3, you can see that different sources of weather data report different irradiance values for the same location, and that the ranking of values reported by different weather file sources is not consistent from location to location.
Figure 3: GHI values from three source of weather data. Finally, design is usually the biggest driver of yield at your control. Table 2: Yield values for four representative designs in four representative locations. All of these designs have different impacts of shading, temperature and even plane-of-array orientation adjustments.
But not many appreciate how those will vary based on the location, the system type or even the weather file used. As with everything in solar, the devil is in the details! Therefore, you must take into account the specific conditions under which your panels are installed. Do you have a small roof? The number of kWp will help you evaluate the yield you could achieve if you cover it with photovoltaic panels.

Got a question about energy? Ask it here! Ask a question or search for an energy term. Home consumption and rates meters and meterreadings what is the kilowatt-peak? What is the kilowatt-peak? Indeed, there are many elements involved: the location panel orientation the direction of shade the weather the presence of clouds the temperature on the roof … The watt-peak Wp is therefore an indication based on a standard.
To choose your panels The Wp listed by manufacturers makes it possible to compare different photovoltaic panels. To calculate the required panel area Do you want to achieve a certain yield with your photovoltaic system?
