A rooftop tariff proposal raises a question: what is solar electricity worth, and when?

A reported change for 2027 is a reason to examine payment rules and energy timing—not a confirmed new tariff.

Select an underlined term for a short explanation.

For someone considering panels on a roof, a price per unit of electricity can seem like the whole story. On 30 July 2026, Globes reporter Idan Eretz described a possible Israeli rooftop payment of NIS 0.35 per kilowatt-hour from 2027. His report presented an unsettled proposal, not a final regulatory decision. This article explains that dated report; it does not establish today’s applicable rate.

The equipment and the payment rule answer different questions. A photovoltaic cell converts incoming light into electricity: absorbed energy sets electric charges in motion. A rooftop installation brings panels together with other system components. None of that physical description tells a reader which contract applies. SPFI’s reading question is therefore simple: does a quoted figure describe what the equipment produces, or what someone has agreed to pay for it?

Timing adds another distinction. Solar output changes with sunlight, while demand follows its own pattern. Energy storage can move some energy from a period of generation to a later period of use. The US Department of Energy explains that this flexibility comes with conversion losses; electricity placed in a battery is not all returned as useful output.

Power and energy are also different quantities. A battery’s power rating concerns how quickly it can deliver energy; its energy capacity concerns how much it holds. Those measurements help explain why the mere presence of a battery says little about the length of service it can provide. A price comparison that ignores the service being compared leaves an important question unanswered.

The editorial conclusion is to keep three documents conceptually separate: the news report describing a proposal, the eventual regulatory decision, and the terms for a particular installation. The first cannot substitute for the other two. This is a guide to reading the announcement, not a calculation of household returns or a recommendation to sign before a deadline.
