Sonce Energy — website concept for a solar installer

A solar system is an expensive and “invisible” purchase. People spend thousands of dollars on equipment they’ve never seen working and compare several companies that promise roughly the same. In Ukraine in 2026 the decision usually comes down to three reasons: energy bills, power outages and selling surplus power to the grid. The site has to answer each with numbers, not slogans.

The site had four goals:

• qualified requests for a free engineer visit — the main conversion, after which the company designs the system and prepares an estimate;
• self-service calculation — so before the call people understand the price range, the system size they need and the real payback with their own tariff;
• answering the main fear — “will the battery last when the power goes out on a winter evening?”;
• trust without fake reviews — through transparent stages, equipment types without a “favorite brand” and guarantees written into the contract.

The idea — the website as a sunny day. Every section has its own hour: 5:48 am in the hero, 10:30 am at the calculator, 12:30 pm — “peak generation” — at the packages, 7:40 pm for the blackout test, 9:15 pm at the site-visit request. A small “sundial” in the header moves the sun along an arc as you scroll.

Visual language. A bright, optimistic palette: sunny yellow, turquoise, white and a deep graphite green for contrast. Instead of stock photos — a custom SVG illustration system: a house with panels, an equipment diagram, a roof plan with the panel layout, a warehouse with rows of panels and a night street where only one house is lit.

Interactive selling points:

• a “living” house in the hero: the sky, sun, clouds and window lights change throughout the day, and a monitor card shows energy flowing between the panels, the house, the battery and the grid — including during a scheduled outage;
• a system calculator by consumption or roof area, with region and goal (savings, backup, selling surplus), that works out system size, number of panels, battery capacity, inverter type, a price range and payback; tariffs are editable, and there are no unverified government rates;
• monthly generation and 15-year cumulative savings charts that account for panel degradation;
• a blackout test that models battery charge hour by hour for the season, outage schedule and battery size, shows the hours without power and suggests the smallest battery that covers the schedule;
• 5/10/30 kW packages, an equipment diagram with component highlighting and a site-visit request that automatically pulls in the calculation, the blackout-test result or the chosen package.
