Explore practical guides, understand your options and prepare the right questions for your installation.
Understand energy flows, the difference from Net Metering and the consumption, site and connection data needed for a solar PV assessment in Crete.
Read the guide: Net Billing in Greece: a self-consumption guideCompare the scope of Net Billing quotations and calculate simple payback using self-consumption, exports, operating costs and explicit assumptions.
Read the guide: Net Billing cost and payback: a calculation methodUnderstand zero-export metering, inverter control, curtailment and commissioning, and why Zero Feed-In is neither off-grid operation nor automatic approval.
Read the guide: Zero Feed-In: how solar export control worksDistinguish self-consumption from a billing arrangement, calculate two different energy ratios and understand the role of batteries and zero export.
Read the guide: Net Billing versus self-consumption: the distinctionPrepare supply information, site rights and technical documentation for a PV connection, using current HEDNO instructions rather than assumed deadlines.
Read the guide: Connecting solar PV through HEDNO: preparation guideAssess solar storage using daytime surplus, evening loads, round-trip losses, battery utilisation and the distinction between energy storage and backup.
Read the guide: Solar PV with batteries: when storage makes senseSize storage from energy demand, load power, usable capacity and required autonomy. A worked example explains the difference between kW and kWh.
Read the guide: How much solar battery capacity do you need?Compare LiFePO4 storage using BMS compatibility, usable energy, continuous power, temperature limits and warranty conditions rather than capacity alone.
Read the guide: LiFePO4 solar batteries: selection criteriaEvaluate a Huawei inverter using its exact model, MPPT limits, battery compatibility, monitoring and backup configuration rather than brand-level claims.
Read the guide: Huawei inverters: applications and selection checksUnderstand hybrid inverter energy flows, AC versus DC coupling, battery compatibility and why grid-output power can differ from backup capability.
Read the guide: Hybrid inverters: functions, limits and backupPlan off-grid electricity around measured loads, winter generation, battery reserves, inverter power and a practical strategy for low-sun periods.
Read the guide: Off-grid solar PV: a system design guidePlan an autonomous home around appliances, heating, seasonal occupancy, critical loads and simultaneous power rather than floor area alone.
Read the guide: Off-grid solar for a home: practical planningAssess a 10 kW solar installation using panel count, roof constraints, location-specific yield, quotation scope and battery requirements.
Read the guide: 10 kW solar PV: cost, roof space and generationWhen to assess a 15 kW PV system, how array size affects self-consumption and which electrical, roof and quotation details need checking.
Read the guide: 15 kW solar PV: sizing, generation and quotation checksEstimate PV yield in Crete using site-specific PVGIS inputs, shading, orientation and system losses, and distinguish generation from actual bill savings.
Read the guide: How much electricity does solar PV produce in Crete?Understand solar payback assumptions, operating expenses, replacement scenarios and the difference between simple payback and a complete cash-flow model.
Read the guide: Solar payback: from a simple ratio to cash flowChoose PV capacity from consumption timing, roof space, shading and future loads. A worked first estimate explains why annual bills alone are insufficient.
Read the guide: What size solar PV system do I need?Assess commercial PV using interval demand, weekends, seasonal operations, export control, storage requirements and a practical handover plan.
Read the guide: Solar for businesses: assessing the investmentPlan hotel solar around occupancy, cooling, pools, hot water and roof constraints, with a published 10 kW installation in Zaros as a project reference.
Read the guide: Hotel solar PV: seasonality and operating profilesAssess farm solar using seasonal demand, pump starting power, irrigation schedules, refrigeration continuity and actual water-service requirements.
Read the guide: Agricultural solar: pumping, refrigeration and storageWorked examples are explicitly labelled. Actual generation, connection terms and savings need a site-specific assessment.
