Charge your Electric Car with your own Photovoltaic Electricity and enjoy 100% Emission-Free Driving
Charging an electric car with the power from your own photovoltaic system (PV system) is a rewarding experience. After all, a PV system with an output of 5 kWp can supply up to 5000 kWh (kilowatt hours) of electricity per year. If your electric car has an energy consumption of 17 kWh/100 km, then you are driving almost 2,500 km per month emission-free. So charging your electric car with PV power not only takes the strain off your ecological conscience, but your wallet too.
Charge with PV Power and save Money as you increase Consumption
Due to decreasing rates of remuneration for feeding power into the grid and increasing electricity costs, the private consumption of PV electricity is gaining in importance. Instead of selling on privately generated electricity at low prices (remuneration for new systems under the German Renewable Energy Sources Act stood at 12.3 cents/kWh in Sept. 2015), you should consume or temporarily store as much of this power as possible yourself. You can increase your own consumption for example by using PV power to charge your electric car and by implementing intelligent consumption regulators such as the smartfox Energy Manager. Today, the saving for every kilowatt hour you consume yourself is already up to 18 cents. This is because you do not need to draw any expensive power from the electricity grid (26-30 cents/kWh), or temporarily store the PV power you have generated in the electricity grid for higher costs. Our Self-Consumption Calculator helps you to estimate the potential savings from maximising the use of your self-produced energy.
Supply your Household, Electric Car and the Electricity Grid with at least 5 kWp of PV Electricity – here’s how:
When using PV power, the maximum charging power for your electric car depends on factors such as the size of your PV system and the consumption profile of other appliances in your household. The larger your PV system and the smaller the electricity consumption of your household appliances, the greater the maximum charging power available with PV electricity. With a system capacity of 5 kWp and domestic consumption of 1 kW, 3.7 kW will still be available for single-phase electric car charging at a charging station. There will also be 0.3 kW left over to be fed into the electricity grid.
Charge your Electric Car Emission-Free with PV Power one day, and use your Car as an Energy Storage unit the next – from Uni-Directional to Bi-Directional Charging
There are two basic ways to connect your electric car to a PV system:
