Is a PV Prosumer system including heat and e-mobility a worthwhile investment for me?

The following calculation tool will answer this question by comparing the cost per kilowatt hour (kWh) PV electricity with your current grid electricity and heat generation costs. To achieve this, in a first step you will need to input a few key parameters for your location and project.

Location

Please search for your address or pinpoint your location on the map below. This tool supports Austria, Belgium, France, Germany, Italy, Portugal, Spain and the Netherlands. The location will be used to determine the yearly solar irradiation in your area.

Electricity Consumption

This section lets you set up key inputs for your current electricity consumption that will (partly) be replaced by solar PV. This also includes electricity consumed by an optional electric vehicle.

Yearly Electricity Consumption (kWh)

Please enter your total yearly electricity consumption.

Electricity Consumption Profile (Hourly)

Please select a profile that matches your daily cycle of electricity consumption over a year.

Yearly Distance (km)

Please enter the yearly distance traveled with the electric vehicle.

Electric Vehicle Charge Profile

Please select the daily profile for charging your electric vehicle.

Electricity Price (€/kWh)

Please enter your current grid electricity price (variable components only, excluding VAT).

Third Party Electricity Consumption

In case you are able to sell excess PV electricity to a nearby third-party, you can set this up in this section.

Yearly Electricity Consumption (kWh)

Please enter the total yearly electricity consumption of the consumer you are planning to sell electricity to.

Electricity Consumption Profile (Hourly)

Please select a profile that most likely matches the daily and seasonal cycle of electricity consumption of the third-party consumer over a year.

Electricity Sales Price (€/kWh)

Please enter a reasonable electricity sales prices, this maybe slightly lower than the grid electricity price of the consumer you are selling to (excluding VAT).

Feed-in Tariff (€/kWh)

Please enter the Feed-in Tariff that is applicable for your potential PV installation.

Heat Consumption

By adding a heat pump the PV system can (partly) replace your existing heat source to generate savings. This sections allows to set key inputs for your heat consumption.

Yearly Heat Consumption (kWh)

Please enter your total current yearly heat consumption.

Heat Source:

Please select your current heating source.

Heat Consumption Profile (Hourly)

Please select a profile that matches your profile of heat consumption over a day and a year.

Heating Costs (€/see JS function changeheatcosts())

Please adjust the heating costs for your selected heating source (excluding VAT).

PV System Parameter

In case you plan to install your PV system on a pitched roof, please adjust the inclination and orientation of the roof to match your roofs characteristics. Otherwise, you can leave the pre-entered inputs.

Available roof space (m²) for PV

kWp

Please enter the roof space that is available for the PV module installation.

Inclination PV-modules (pitch)

Please adjust the arrow to set the pitch of your roof. In case of a flat roof, 30° is a good value for Europe.

Orientation PV-Modules (azimuth)

Please adjust the arrow within the circle to set the orientation of your pitched roof.

Based on your inputs in Step 1, some key economic figures for your project are shown below. The main calculation results are displayed in the right box. In order to adjust the calculations to your individual case you need to answer some further key questions by adjusting the sliders below each chart. Your adjustments will directly influence the economic results in the box on the right.

Calculating tool data, this will take about 20 seconds. Processing step 1 of 2.

LCOE (EUR/kWh)
The Levelized Cost of Electricity (LCOE) is an economic assessment of the total cost to build and operate a power-generating asset over its lifetime divided by the total energy output of the asset over that lifetime.
Payback Period (Years)
The duration required for an investment to recover its initial outlay in terms of profits or savings.
Equity IRR (% p.a.)
The calculation of the internal rate of return (IRR) considering the cash flows net of financing gives us the equity IRR.
Project IRR (% p.a.)
The Project IRR is calculated without considering the financing structure (debt equity ratio) of a project. If the project is fully funded by equity, the project IRR and equity IRR will be the same.
Net Present Value (EUR)
Net-Present Value (EUR) is the difference between the present value of cash inflows and the present value of cash outflows. Present value (PV) is the current worth of a future sum of money or stream of cash flows given a specified rate of return. Future cash flows are discounted at the discount rate, and the higher the discount rate, the lower the present value of the future cash flows.

How much does your PV system cost per kWp?

If you have received an quote from a PV installer simply divide your total cost by the system size in kWp.

Cost of solar PV electricity (LCOE)

System Cost (€/kWp):

Which operating time of the system are you willing to use for the calculation?

20 years are commonly used for the system, and costs for replacing components with a shorter lifetime (inverters, batteries) are already considered in the calculations. Quality modules come with warranties above 20 years and will most likely operate up to 30 years under good maintenance conditions.

Cost of solar PV electricity (LCOE)

Duration of system operation (years):

What is the debt interest rate you are getting from your bank?

Individual interest rates for commercial loans apply if the system is based on self-consumption or on a supply contract without a feed-in tariff as fall back option.

Interest Rate (% p.a.):

What is the yearly average electricity price increase you expect for the operations period of the system?

The electricity price increase in % p.a. has a significant impact on a systems economics. In recent years we have seen steep increases in many countries. However, in the longterm this yearly increase will probably average in the range of the longterm inflation rate.
