Solar Design Romania
Energy Usage
How much energy your Romania home uses daily directly impacts the solar system size you'll need. The average household uses around 15 kWh per day, whilst energy efficient properties may use only half that.
It's worth reducing your energy usage before going solar, as this can decrease the system size you need and improve payback. Focus on better insulation and energy efficient appliances.
Typical energy usage per person per day in Romania:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
Matching your daily energy needs requires approximately 3.9kW of solar capacity. Optimal sizing ranges from 5.9kW to 7.9kW to accommodate daily and seasonal generation variations.
A 6.6 kW system in Romania generates approximately 26.7 kWh daily on average, with seasonal variation from 2.78 kWh/kW/day in December to 4.73 kWh/kW/day in August.
Solar & Energy Savings
Calculate Heat Pump & EV Savings
Electrify your home by replacing gas heating, petrol vehicles, and other fossil fuel appliances with electric alternatives powered by clean solar energy. This delivers significant additional financial savings and substantial carbon emission reductions. Our calculator helps you compare costs and model the financial impact of switching to electric appliances and vehicles.
How Solar Reduces Your Electricity Bills
The calculations below show how your electricity bills change with solar. Your Old Bill of - per month (- annually) is calculated from your total energy consumption multiplied by the grid electricity rate. Your New Bill of - per month (- annually) accounts for solar generation, the percentage you use directly (self-consumption), remaining grid consumption, and feed-in credits for excess energy exported to the grid. This results in monthly savings of - (- annually).
Battery Storage Romania
Solar Battery Sizing
Without battery storage, a 6.6 kW system in Romania achieves approximately 50% energy self-sufficiency, with the remaining 50% supplied by the grid. With a 10 kWh battery added, energy independence increases to approximately 99% per year, whilst grid dependency falls to 1%.
The full Photonik tool provides detailed battery savings and return on investment calculations.

Solar & Battery System Cost Romania
Understanding Solar & Battery System Costs
A 6.6 kW solar system in Romania costs approximately lei47,524, while adding a 10 kWh battery increases the total to around lei77,594. Solar installations typically pay for themselves within around 10.9 years, whilst batteries extend payback but deliver significantly higher energy independence.
The breakdown covers equipment, installation, and taxes. Adjust the system size and battery sliders to see how different configurations affect your investment and payback timeline.
