Construction of solar PV systems (On-Grid, Off-Grid, Net Billing and Zero Feed-In), industrial UPS with batteries, Smart Home solutions and specialist installations. Efficient delivery, clean workmanship and proper technical documentation.
About us
The Green Action Energy delivers complete solutions in solar PV, battery storage and electrical installations for homes, businesses and industrial facilities. Our goal is a technically sound project: proper engineering, quality materials and clear documentation.
We serve Heraklion, Rethymno, Chania and, more broadly, Greece. Whether you need Net Billing, Zero Feed-In or Off-Grid (off-grid), we design the system around your consumption, objectives and available space.
For technology details and available options, see Services or send your details through the contact form for a tailored proposal.
Practical articles with examples and useful questions before your next installation.
Understand energy flows, the difference from Net Metering and the consumption, site and connection data needed for a solar PV assessment in Crete.

Illustrative calculator, not a quotation or performance guarantee. It uses fixed cost assumptions and annual generation of 1,700 kWh per kW, not a study of your property. Actual savings depend on self-consumption, shading, losses, tariffs and settlement terms. This is not a complete Net Billing financial analysis.
We have collected the questions we most often receive about residential and commercial installations in Crete and throughout Greece.
