Can energy toolbase accurately calculate exported energy?

Note: Energy Toolbase can only accurately calculate exported energy if a user references an ‘Energy Use Profile’ that has interval meter data. If you reference an ‘Energy Use Profile’ using monthly summary data, we simply assume that inputted kWh energy usage is evenly distributed throughout all intervals in a billing cycle.

How do I calculate the 'avoided cost' or 'value of solar'?

Calculating the ‘avoided cost’ or ‘value of solar’ requires calculating how much energy (kWh) gets exported to the grid. On the ‘Edit Proposal’ screen, users can reference how much energy is exported in % terms inside the ‘Meters’ section.

Is the exported energy value a good indication of exported energy?

Therefore, the exported energy value we calculate using monthly summary data is not a good indication of exported energy. Non-Bypassable Charges (NBC’s) NBC’s are volumetric based ($/kWh) charges that a customer must pay on all energy they ‘import’ from the grid. In other words, these charges cannot be offset by solar exports to the grid.

What is the difference between imported energy and exported energy?

During the day when the sun is shining, imported energy would occur when the facility is using more energy (kWh) than the PV system was generating. Exported Energy, measured in kWh, is energy that is back-fed to the grid. In other words, the solar system was producing more energy (kWh) than the facility was using, during a given interval.

Is energy use profile a good indication of exported energy?

If you reference an ‘Energy Use Profile’ using monthly summary data, we simply assume that inputted kWh energy usage is evenly distributed throughout all intervals in a billing cycle. Therefore, the exported energy value we calculate using monthly summary data is not a good indication of exported energy.
