FAQs
What makes your solar installations in Athens innovative compared to conventional systems?
Our solutions combine high-efficiency N-type photovoltaic modules with smart micro-inverters and AI-driven energy management. This architecture maximises production in Greece’s intense summer heat, reduces shading losses common in urban Athens, and lets homeowners monitor each panel in real time via a mobile app. In addition, we integrate battery storage and EV-charging ready circuits so your system is future-proof from day one.
How do Athens’ climate and local regulations affect the design and permitting of a solar project?
Athens enjoys roughly 2,800 hours of sunshine annually, allowing us to size arrays for 1.2–1.4 kWh of yearly production per watt installed. However, high summer temperatures can lower panel output, so we use temperature-resistant modules and elevated racking for better airflow. Regarding permits, systems up to 10 kWp on a primary residence require a simple notification to DEDDIE (the Hellenic Electricity Distribution Network Operator); larger or commercial projects need an environmental and grid-connection study. We handle the entire paperwork chain, so clients sign only once.
Can your solar system integrate with my existing electrical infrastructure and future smart-home upgrades?
Yes. We carry out a load-analysis of your current electrical panel and install a dedicated solar sub-board with surge protection. All inverters are compatible with three-phase or single-phase supplies and can communicate over Wi-Fi, Ethernet or Modbus. If you later add a battery, heat pump, or EV charger, the same energy-management gateway can automatically prioritise self-consumption, minimising exports to the grid while keeping critical loads powered during outages.
How long does the installation take, and will my daily routine be disrupted?
Most residential projects (4–10 kWp) are completed in 1–2 days on the roof and half a day for electrical tie-in. Commercial systems may take 1–2 weeks depending on roof complexity. Our crews use non-penetrating mounts where possible, reducing noise and debris. Power is only shut off for about 30 minutes during the final grid connection, and we clean the site thoroughly before departure.
What savings and payback period can I realistically expect?
For a typical 6 kWp home array in Athens, annual production is around 9,000 kWh. At current retail tariffs (~€0.18/kWh), that equals €1,600 in yearly savings. Factoring in the new net-metering scheme and the 30 % state subsidy (if eligible), the simple payback ranges from 4.5 to 6 years. With electricity prices trending upward, lifetime internal rates of return of 12–15 % are common, and the system will continue generating for 25+ years.
What warranties, maintenance, and monitoring services are included after installation?
We provide a 25-year linear performance warranty (≥84 % output in year 25) and a 12-year product warranty on panels, extendable to 25 years. Micro-inverters carry a 25-year replacement guarantee, while mounting hardware is covered for 20 years against corrosion. Annual preventive maintenance—string inspection, thermal imaging, and IV-curve testing—is included for the first two years and optional thereafter. Clients receive lifetime access to a cloud portal that sends instant alerts if production drops, and our Athens service team can dispatch technicians within 48 hours.
