Common Technology Questions
Estonia is transitioning rapidly to clean, distributed energy. Learn how system installations are handled, connected, and maintained in compliance with local specifications.
During mid-winter, daylight hours in Estonia are short, and snow may temporarily cover panels. We design solar arrays with optimized tilt angles (typically between 35° and 40°). This angle ensures that when the sun emerges, the dark silicon absorbing heat naturally triggers snow to slide off. Additionally, our mounting frames carry professional snow-load ratings, ensuring structural safety even under heavy snow cover.
When your solar array produces more electricity than your home consumes, the surplus is automatically fed back into the public grid via a smart bidirectional meter. You sell this electricity to your energy provider at the current Nord Pool spot price. To enable this, you need a grid connection agreement with Elektrilevi. Arton Solar OÜ handles all audit preparations and filings to finalize this connection for you.
Yes, in most Estonian municipalities (including Saku, Harjumaa), installing solar panels requires submitting a construction notice (ehitusteatis) and a project design blueprint to the national register (Ehitusregister). If your home is located in a protected heritage area, additional approvals are needed. We handle the drafting of architectural drawings and submit all necessary municipality requests on your behalf.
A hybrid inverter manages power input from solar panels, grid electricity, and home storage batteries simultaneously. Installing a hybrid inverter from the start allows you to connect a battery backup system later without having to pay for a costly replacement inverter. We install premium hybrid models by default to future-proof your investment.
EV chargers can draw significant current, posing a risk of tripping your home's main circuit breaker. To prevent this, we install smart EV chargers equipped with dynamic load balancing (DLB). This system monitors your home's real-time electricity consumption and adjusts the EV charging speed accordingly, prioritizing household appliances and preventing fuse overloads.
We believe that energy autonomy and digital privacy are closely linked. Our smart energy calculation tools and mobile configurations are designed to run in a secure, sandboxed local environment on your device. We do not track your energy profiles, location, or usage patterns. What happens in your home electrical loop should remain private to you.
