Solar System Size Calculator: Cyprus kWp Guide 2026

Why Sizing Matters More in Cyprus Than Almost Anywhere

Cyprus receives around 2,000 peak sun hours per year — among the highest in Europe. That is excellent news for solar yield, but it also means a system that is even slightly oversized will generate large summer surpluses that can expire at the end of your 12-month EAC net metering window. Precision sizing is financially important.

Step 1: Find Your Annual Consumption

Start with your EAC bills. Add up 12 months of consumption figures (in kWh) to get your annual total. If you do not have all 12 months, take a single recent bill, check how many days it covers, and extrapolate.

Typical Cyprus household annual consumption benchmarks:

Step 2: Decide Your Coverage Target

Most Cyprus homeowners target 80–100% solar coverage of annual consumption. However, if you have significant winter loads (electric heating, heat pump), a 100% coverage target will result in a large system that over-generates dramatically in summer.

A practical target for a typical Cyprus home is 70–85% annual coverage — this typically means the system breaks even on net metering credits across the year with minimal wastage.

Step 3: Apply the Cyprus kWp Formula

Use the PVGIS irradiance figures for your location. Cyprus averages:

• Nicosia (inland): 1,870–1,950 kWh/kWp/year
• Limassol (coastal): 1,800–1,880 kWh/kWp/year
• Paphos: 1,820–1,900 kWh/kWp/year
• Larnaca: 1,810–1,870 kWh/kWp/year

These figures assume a south-facing roof at 25–30° pitch and include system losses of around 14–16%.

Formula:

Required kWp = (Annual kWh target) ÷ (PVGIS yield for your location)

Example — 3-bedroom Nicosia house:

• Annual consumption: 7,200 kWh
• Coverage target: 80% = 5,760 kWh from solar
• PVGIS yield (Nicosia): 1,900 kWh/kWp/year
• Required kWp: 5,760 ÷ 1,900 = 3.03 kWp
• Practical system size: 3.3 kWp (rounding up to panel count)

Step 4: Cross-Check Against Roof Space

Modern 420–450 W monocrystalline panels measure approximately 1.72 m × 1.13 m (about 1.95 m²). A 3.3 kWp system needs roughly 8 panels, requiring about 16 m² of usable south-facing roof area.

For larger systems:

Step 5: Adjust for EV Charging or Battery Storage

If you plan to charge an electric vehicle from solar, add the EV energy load to your calculation. A typical EV driving 15,000 km/year in Cyprus consumes around 2,700–3,300 kWh annually at home (assuming 6–7 km/kWh). Add this to your base consumption before applying the formula.

If you are adding battery storage, you can slightly downsize the array because the battery captures midday surplus that would otherwise be exported at the lower EAC credit rate, increasing overall self-consumption.

Seasonal Split: Getting the Balance Right

Run your calculation for both summer (June) and winter (December) separately to check the seasonal extremes:

• In June, a 6 kWp system in Limassol generates approximately 900 kWh — well above typical monthly consumption
• In December, the same system generates approximately 330 kWh — often below monthly consumption

The 12-month net metering window smooths this out. The key metric to check is whether your total annual surplus (summer generation minus summer consumption) roughly matches your annual winter deficit.

Common Sizing Mistakes in Cyprus

• Using UK or German yield tables — Cyprus irradiance is 30–40% higher; this error leads to systematic undersizing
• Ignoring summer A/C loads — a home that runs air conditioning heavily in summer can self-consume much more solar than a winter-focused analysis suggests
• Sizing only for grant eligibility — the MECI grant maximum of 10 kWp per residential property should not constrain sizing if your loads justify a larger system
