A preliminary engineering estimate, not a quote. Real figures depend on the site, the bill, the equipment and the approval.

Assumptions and sources
  • A representative day of the chosen month, from long-term PVGIS averages. Clouds and heatwaves are not modelled. Months other than June and December blend the two day shapes.
  • Home use is an illustrative home profile scaled to the bimonthly consumption you entered. Every month uses the same daily use.
  • Battery: 88% round-trip efficiency, a 10% reserve, charged from solar surplus only, never from the grid. In evening-only mode it discharges 17:00 to 23:00.
  • Car: kWh per 100 km at the plug, charging losses included. The charger runs at full power from the start of its window.
  • Official tariffs from 1.7.2026, VAT included on consumption. The PV tariff is taken as paid, without VAT, for a private household. Fixed charges that are the same with and without a system are not shown.
  • The saving is measured against the bill today: no system, on the flat tariff. On TOU the fixed charge is higher, and the difference is added to the cost with the system: for a three-phase household connection below 3×100 A, ₪56.20 a month against ₪31.97 on the flat tariff, VAT included.
  • A PV owner pays an extra fixed charge of ₪23.28 a month, VAT included. It is added to the cost with the system under both arrangements.
  • Under the injection arrangement, a system tariff of 10.96 agorot per kWh, VAT included, is paid on every solar kWh that is not exported: what is used at once and what goes into the battery.
  • Arrangements for requests filed by 31.12.2026. Accelerated or CPI-linked tracks and the complementary payment for battery export are not modelled.
