Bask in the brilliance of Attica’s sunshine with HEP’s cutting-edge solar panels, engineered in Europe and perfectly tuned for the climate of Athens. Our technicians map every rooftop with precision drones, then pair high-efficiency PV modules with smart inverters that whisper instead of hum, ensuring seamless integration with your home’s electrical system. From the first sun-lit kilowatt to the final sleek cable run, each solar installation maximizes output while preserving the city’s timeless aesthetic.
Choose HEP and step into a future where your meter spins backward, your carbon footprint shrinks, and your energy bills all but disappear. We handle permits, net-metering paperwork, and real-time monitoring apps, so you simply enjoy guilt-free power and a return on investment that accelerates with every clear Mediterranean day. Join the Athens community already harvesting clean energy—because the sun doesn’t send invoices, and neither should your utility.
FAQs
How much solar electricity can I expect to generate in Athens?
Athens enjoys an average solar irradiation of 1,600–1,700 kWh/m² per year. A typical 5 kWp rooftop system will therefore produce roughly 7,500–8,000 kWh annually—enough to cover most households’ consumption. Because we use high-efficiency monocrystalline modules (over 22 % module efficiency), production is maximised even on hot summer days. Our design software models your exact roof orientation, tilt, and shading to give you a site-specific yield forecast before you sign any contract.
What does the installation process involve and how long will it take?
1. Technical survey (1–2 days after inquiry): We visit your property, assess roof condition, electrical panel, and meter location. 2. Engineering & permits (1–2 weeks): We create a customised system layout, single-line diagrams, and submit paperwork to ΔΕΔΔΗΕ for net-metering approval. 3. Equipment delivery & mounting (1–2 days): Aluminum racking is anchored to your roof and panels are fixed in place. 4. Electrical integration (1 day): DC cabling, inverter placement, AC connection to your distribution board, and smart meter installation. 5. Commissioning & grid sync (1 day): ΔΕΔΔΗΕ inspects and swaps the meter; we run performance tests and show you the monitoring app. For a standard residential project the on-site work takes 3–4 days, while the total timeline is typically 3–5 weeks, depending on permitting speed.
Are there financial incentives or net-metering schemes available in Greece?
Yes. Greece operates a nationwide net-metering program (Νet-Μetering 1 / 2023) that credits each kWh you feed into the grid against the kWh you import, rolling the balance for up to three years. You pay only the fixed grid fees on your bill. Additionally, the new "ΗΛΕΚΤΡΑ" program offers subsidies of 45–65 % for home PV plus battery storage, subject to income criteria. Businesses can also deduct 100 % of the investment as accelerated depreciation in the first year. We handle all application paperwork and keep you informed about upcoming funding calls.
How much maintenance do the panels require and what is their lifespan?
Solar PV is largely maintenance-free. Athens’ occasional rain keeps panels reasonably clean, but we recommend rinsing them once or twice a year to remove Saharan dust. Our service plans include an annual inspection: thermal imaging, IV-curve testing, and mounting-torque checks. The modules carry a 25-year performance warranty (at least 88 % output in year 25) and a 12-year product warranty. Inverters are covered for 10 years (extendable to 20). Expected system life exceeds 30 years.
Will the system work during cloudy days or power outages?
High-efficiency cells still generate 10–30 % of their rated power under heavy cloud cover, and our MPPT inverters optimise for low-irradiance conditions. However, for safety reasons a standard grid-tied PV system shuts down automatically during a grid failure (anti-islanding). If you want backup power, we can integrate a hybrid inverter and lithium battery pack that forms a local micro-grid, keeping critical loads (fridge, lights, router) running for several hours.
What warranties and after-sales support do you provide?
• 25 -year linear performance warranty on panels. • 12-year product warranty on panels (extendable to 25). • 10-year warranty on inverters and optimisers (extendable to 20). • 5-year workmanship warranty covering roof penetrations, cabling, and mounting structures. • Free online monitoring platform with lifetime access. • Priority customer support: on-site response within 48 hours in the Attica region and remote troubleshooting within 4 hours. Our Athens-based service team stocks critical spare parts, ensuring minimal downtime if an issue arises.
