# Finacial Analysis/Economic Efficiancy Clculation

## Recommended Posts

Hello everyone,

I am hoping someone may be able to help with a few queries around the Financial Analysis & Economic Efficiency Tab and what each tab refers to.

The basic figures I am wanting to input are:

Cost to customer is £25,272.00

Cost per kWh for my customer is 0.34p

Annual kWh is 15,600kWh

Consumption to be used on site will be 90% (he is also having battery storage)

The remaining 10% will be sold back to grid at 7.5p kWh

When I am looking at the simulation results the annual yield is only at 990 kWh/kWp but the we know the yield will be circa 28,000 kWh

I am just just confused as to what I should be inputting where, any help will be very much appreciated.

I am trying to get my company to purchase the software and looking to show them an example using one of my directors properties.

Many thanks for any help

Dan

Hello Dan Ogden,

You did put this right, it is the investment costs of your customer.

You can create your own from-grid tariff with those 0.34p per kWh:

You have to put this value as Consumption. If you have measured values, perfect. If not, you have to estimate typical distributions.

You have to create your own feed-in tariff with the value of 7.5p per kWh:

The 990 is specific, which means 990kWh per kWp. Regarding you 32.4kWp generator output this yields to ~32,000kWh.

I hope this gives some hints into the right direction! If you have further questions, feel free to ask!

Kind regards,
Frederik
