Solar Panels for Home – Installation & Design 2026
A residential solar panel system is the most profitable investment a household can make today. With proper design and installation, you can cover up to 80-100% of your energy needs, protect yourself from rising electricity prices, and recover your investment in 2-6 years.
What size solar system do you need?
- 🏠 3kW — 1-2 person household, low consumption (~4,000 kWh/year)
- 🏠 5kW — 3-4 person household, medium consumption (~6,500 kWh/year)
- 🏠 8-10kW — Large home, air conditioning, electric vehicle
- 🏠 10kW+ — Villa, apartment building, farm with high energy needs
Our engineers provide a free energy study to determine the exact system size based on your annual bill, roof orientation and any shading.
Net Billing & Zero Feed-In: how it works in Greece
In Greece, the current system is net billing — not net metering. The principle is simple: consume what you produce first, and the inverter is configured for Zero Feed-In so that no energy is exported to the grid.
- ⚡ Self-consumption first — the electricity you produce powers your appliances directly
- 🔋 Store the surplus — excess production (e.g. midday) is stored in a battery for nighttime use
- 🚫 Zero Feed-In — the inverter exports zero energy to the grid, maximising every kWh
- 📉 Minimal electricity bill — you only pay for consumption beyond your production
Correct system sizing (power + battery capacity based on your consumption profile) is the key to zero dependence on the grid. That is exactly what the Iliatoras design team delivers.

Frequently Asked Questions
Do I need a permit for rooftop solar panels?
For systems up to 10.8kW on a residence, no building permit is required — only a DEDDIE connection. Iliatoras handles all the paperwork.
What about maintenance?
Solar panels require minimal maintenance — mainly cleaning 1-2 times a year. Our telemetry system automatically detects any faults.
Can I add a battery later?
Yes — our systems are compatible with battery storage at any time. Adding storage significantly increases your energy independence.
How long does installation take?
Residential systems up to 10kW are installed in 1-2 days. DEDDIE connection follows within 2-6 weeks.
