Peak demand, wind, solar and back-up power / energy usage and storage capacity calculator

For the specification and design of renewable energy electricity generation systems which successfully smooth intermittent wind and solar generation to serve customer demand, 24 hours a day, 7 days a week and 52 weeks a year.

Adopting the recommendation derived from scientific computer modelling, the tables offer rows of previously successful modelled system configurations – row A, a configuration with no back-up power and rows B to H offering alternative ratios of wind and solar power to back-up power.

The recommended energy storage capacity is about 90% of one day’s average wind and solar energy generation.

The tables’ columns consist of power and energy variables.

A cell value can be adjusted according to the design criteria and then all the other table values will be recalculated, spreadsheet-style.

The wind and solar power generation Capacity Factor (C.F.) percentages can be adjusted too.

The energy generation percentages from wind and solar power can be adjusted, either directly or according to the latitude of the system.

A configuration text page for a row which has been adjusted and designed satisfactorily can be opened for text output by clicking on the row’s “TXT” icon in the “Open text page” column.

The recommendations derived from modelling are only specified to 2 significant figures so take with a pinch of salt any apparently third “significant” figures in the numbers output in the configuration text pages.
