How to size solar from a two-month electricity bill in Cyprus

Start with the full billing period

If your electricity bill covers two months, enter the whole amount in our calculator. There are six such periods in a year. An average bill of €360 per two-month period means €2,160 per year. It does not mean €4,320.

Actual billed kWh are more useful than the euro total for system design. Prices, fixed charges and adjustments can change while your appliances consume a similar amount of electricity. Collect all six bills and check the dates rather than assuming every period contains the same number of days.

Separate consumption from the price you pay

Write down the kWh for each period, the tariff code and any fixed charges. A simple euro-based estimate divides the variable part of your annual spend by an assumed import price. For example, €2,160 divided by an illustrative €0.30/kWh gives 7,200 kWh per year if no fixed charges are deducted. That assumption is deliberately visible in our calculator; it is not an official EAC rate.

Why annual generation is only part of the answer

A system that generates as much electricity as your annual use does not automatically eliminate the bill. Generation and consumption happen at different times. Air conditioning, a pool pump, working hours and evening cooking all affect how much solar electricity you use directly. A battery can shift some energy, but its additional cost also needs to be assessed.

The website's monthly chart is an illustrative seasonal profile. It helps explain the relationship between generation and demand. A project proposal needs the actual roof, orientation, shading, equipment, losses and your consumption pattern.

What to prepare for a tailored proposal

• Six two-month bills, with the kWh and tariff visible.
• Photographs of the roof, switchboard and proposed inverter location.
• Information about daytime occupancy, cooling, pool pumps and planned new loads.
• Your priorities: bill reduction, a battery, backup or a future expansion.

Then compare the proposed power in kWp, expected annual generation in kWh, direct use, exports and the assumptions behind any payback estimate. More panels are useful only when the full design and economics support them.
