What is this tool used for?
Compare the same daily energy and use one currency throughout. Prices stay fixed; financing, replacements and equal backup reliability are not modelled.
How this is calculated
Cɢ = C₀ɢ + n × (365 × E × f × c + Mɢ); Cₛ = C₀ₛ + n × Mₛ; C₀ɢ = Generator purchase cost; n = Analysis period · years; E = Daily energy demand · kWh; f = Fuel use · L/kWh; c = Fuel price per litre; Mɢ = Annual maintenance cost; C₀ₛ = Net upfront system cost · currency units; Mₛ = Annual solar maintenance
Before you use the result
