Answers to our most frequently asked questions
When sunlight reaches your solar panels, each panel — made up of multiple solar cells — converts solar radiation into electricity. Inside every solar cell, the silicon layers generate a voltage that forms direct current (DC).
This current travels through cables to an inverter, which transforms DC into alternating current (AC) — the type of electricity used to power your home or business.
From there, the electricity flows into your electrical panel (fuse box) and is distributed to your outlets and appliances.
If your system produces more electricity than you use, the excess power is sent through your electricity meter back to the national grid. You can then sell this surplus electricity to your current electricity provider or another of your choice through a production agreement.
During sunny hours, your solar panels often generate more electricity than you can use immediately. Without storage, this excess energy is sent out to the grid — meaning that at night or on cloudy days, you’ll still buy electricity back, often at higher rates.
An energy storage system (solar battery) solves this. Connected through a hybrid inverter, it stores the surplus energy your panels produce during the day. Later, when the sun sets, the stored power can be used to run your home — maximizing your self-consumption and minimizing energy costs.
By using your own produced energy, you also avoid transmission fees and extra charges, making your solar investment more profitable and sustainable.
Additionally, private homeowners in Sweden can currently benefit from up to 50% tax deduction on the investment cost of installing an energy storage system.
As electric mobility continues to grow, efficient and safe charging solutions have become essential.
A smart EV charger allows your car to charge dynamically with power ranging from 1.4 kW to 22 kW (both single and three-phase)
Unlike standard wall outlets, smart chargers automatically balance your home’s total power load. A connected load-balancing system continuously monitors your household’s energy usage and directs the remaining available power to your EV — preventing blown fuses even if multiple appliances are running at once.
You can also schedule charging based on electricity prices or specific time slots, optimizing both cost and energy use.
Arka Energy provides complete EV charging solutions, seamlessly integrated with your solar and battery system.
After your system is installed and operational, you can freely choose which electricity provider to sign a production agreement with.
Simply contact your preferred supplier and inform them that you will start producing and selling solar electricity.
For more details about consumer rights and terms, visit your electricity provider’s website or the Swedish Energy Markets Inspectorate (Ei) for official guidelines.
Once your installation is complete, Arka Energy submits a completion report to your electricity company. They will then contact you to inspect the installation and verify that it’s ready to be connected to the grid.
During this process, your electricity meter will be checked to ensure it can measure both incoming and outgoing power.
If your current meter doesn’t support bidirectional measurement, the electricity company will replace it with a new one free of charge. You won’t need to cover any additional costs.
