Battery – Discharge, Solar
For systems with a back-up generator, the proportion of discharge that is based on solar
energy is given separately. The difference from the total discharge comes from the back-up
generator’s portion.
Battery - Losses
Battery losses come from the battery efficiencies during charge and discharge, and selfdischarge.
Battery - Performance Ratio
The battery’s performance ratio is the relationship between discharge and charge.
Charge Condition at Simulation Start/End
The battery’s charge condition at the start of simulation (defined in the system
configuration) and the calculated charge condition at the end of simulation is shown.
Consumption - Requirement
The requirement is the sum of the annual energy requirement of all defined Appliances.
If no appliances have been defined, this value is not given. You are also able to define
appliances if the ”Full Supply” to grid concept has been selected.
Consumption – Covered by Solar Energy
The consumption covered by solar energy is made up of direct energy use and the solar
portion of the battery charge.
Consumption – Not Covered
The consumption requirement that cannot be covered by the system is shown as the
amount of energy required that cannot be provided either by the PV array or by the battery.
Electricity Production Costs
The Electricity Production Costs are the annual costs divided by the amount of electricity
produced.
The annual costs result from the: Cash value of annual costs, One-off Payments, Loan
Payments, Self-Financing
Multiplied by the Annuity Factor.Energy Converter
This dimension is only shown if MPP tracking is going to be used. The losses that occur
when using an MPP tracker are subtracted from the generated energy.
Energy Requirement - Covered by PV Generator
This dimension is only given when the ”Own Use” concept is selected. It is the energy
generated by the solar system that is used to cover the energy requirement of the
appliances.
