Example: If all appliances in a house are simultaneously turned on and consume a total of 6kW, then the peak load is 6kW. Seasonal load calculation accounts for varying power demands throughout different seasons of the year. Solar output can vary depending on the season, so this is crucial for your solar panel system design.
For space load calculations, EnergyPlus uses an integrated simulation methodology that utilizes a heat and mass balance program for calculating space loads and a building systems simulation at the same timestep. The integrated simulation method allows the zone, system and plant to provide feedback to each other for each time step of the simulation.
Equipment that uses electricity to operate is called a load. Loads are the largest single influence on the size of a PV system. It is better to supply some loads with power from other generating means to limit the size of a PV system. For example, powering an electric range in a home with a PV system can be cost-prohibitive.
When planning a residential solar project, a crucial part of the process is understanding and correctly calculating your energy needs. These calculations, known as solar load calculations or better known as just “ load calcs ” are fundamental to designing an efficient and effective solar system as well as better permit submittals.
The lifespan of a solar panel can be calculated based on the degradation rate. System loss is the energy loss in the system due to factors like inverter inefficiency, cable losses, dust, and shading. The amount of solar radiation energy received on a given surface area in a given time is called solar insolation.
In solar gain calculations, the variables in the simulation are less in number than the space load calculation. This is because when computing solar gain, the software requires user inputs like climate, location, building geometry, and fenestration data. The error (based on the standard deviation) associated with these steps is approximately 7-10%.
