Why Rooftop Solar Is Winning Over Consumers

Global Survey Shows 2‑in‑3 Back Solar and Storage

Two‑thirds of respondents in the 2026 Ipsos Energy Transition Barometer – a survey of 46,000 adults across 31 countries – now support renewable energy and storage investment. The same poll finds that 60 % back energy independence and 70 % are anxious about foreign‑energy dependency, signalling a clear shift from environmental motives to economic security.

Rising Energy Costs Drive the Switch

The barometer also reveals that three‑quarters of people worldwide worry about climbing energy bills, and half have already cut back on essentials to keep the lights on. With oil and gas markets volatile, households see rooftop solar as a hedge against price spikes that originate far from their homes.

Solar + Batteries Deliver Immediate Savings

By generating electricity on‑site and storing it for peak‑price periods, a typical home solar‑plus‑storage system can significantly reduce the electricity bill. The financial upside comes from avoiding the highest grid tariffs and from the continued decline in solar module costs.

Policy Momentum: Global Solar Council & Mayors Partnership

In response to the public’s appetite, the Global Solar Council has teamed up with the Global Covenant of Mayors on Energy & Climate to accelerate residential rooftop solar and storage in 14,000 cities worldwide. The partnership aims to streamline permitting, provide financing tools and share best‑practice guidelines, turning consumer demand into concrete projects.

What It Means for Israel

For Israeli households the economics are equally compelling. Using typical Israeli figures – a residential tariff of ₪0.48 /kWh, installation cost of ₪3,150 /kWp and an average yield of 1,700 kWh/kWp /year in the central region – a 10 kWp rooftop system would generate about 17,000 kWh annually, worth roughly ₪8,000 in avoided electricity purchases each year. At a total install cost of about ₪31,500, the simple payback period is just under four years, after which the system continues to produce cheap clean power for the remainder of its 25‑year life. This mirrors the global trend: Israeli owners can lock in low‑cost electricity, reduce exposure to volatile fuel prices and contribute to the nation’s 30 % renewable‑energy target for 2030.

Looking Ahead

As more cities adopt the council‑mayor framework and battery costs keep dropping, rooftop solar is set to become the default choice for energy‑independent households. Future developments are likely to focus on flexible solar solutions for shaded roofs and integrated storage that can be added to existing homes, further widening the market and deepening consumer resilience worldwide.

What It Means for Israel

Using the representative Israeli numbers, a homeowner in the central district who installs a 10 kWp rooftop system will see an annual electricity‑cost saving of about ₪8,000 and recover the upfront investment in under four years. Over the system’s 25‑year life it continues to provide low‑cost, clean electricity while helping the country meet its renewable‑energy goals.
