Solar in Israel, explained for homeowners.

Rooftop solar uses the surface of your roof to generate electricity from sunlight. The roof plane, its orientation and how much of it stays unshaded during the day determine how much of that sunlight is usable.

In Israel, most residential roofs are flat or lightly pitched, often with a parapet, a solar water heater and other equipment already occupying part of the surface. Working around that equipment is a normal part of designing a system.

Photovoltaic panels sit on a mounting structure fixed to the roof. They produce direct current electricity.

An inverter converts that into the alternating current your home uses. Panels, mounting and inverter are the core of any rooftop system.

Electricity produced on the roof can be used by the household as it is generated — appliances, air conditioning, water pumps and everything else already connected.

How much of your production your household uses depends on when you use electricity, not only on how much the roof produces.

A rooftop system does not disconnect your home. Your home remains connected, and the arrangement that applies to you determines how electricity supplied to the grid is treated.

The specific arrangements available in Israel change over time. Bloom will present them here only with a source and a date.

Installing a rooftop system in Israel involves approvals and a grid connection process. This is the part that most often surprises homeowners who did not grow up with the Israeli system.

The exact sequence, and who is responsible for each step in a Bloom project, is being confirmed. We will set it out here once it is.

The economics of a residential system come down to what it costs to install, how much electricity the roof produces, how much of it your household uses, and the arrangement that applies to the rest.

Bloom does not publish a return figure. Any number that ignores your roof is a number about someone else's home.

Usable area, shading from trees and neighbouring buildings, existing roof equipment, and the condition and structure of the roof itself all affect what can be installed.

Bloom's specific roof requirements are being confirmed. Until then, each roof is assessed individually rather than against a published rule.

Panels and inverters carry manufacturer warranties, and a system needs occasional cleaning and checks. Bloom's own maintenance terms are being finalised and will be published here.
