voltaconsolar.eu website review

14 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.4 s.

A phone's processor spends 4.3 s on main-thread work while loading, 891 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 3,897 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 81. Pages that score under 90 lose visitors before the first paint.

Shopify costs a phone 141 ms of main-thread work and 324 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

3 third-party services load with your homepage (Shopify, shop.app and porjs.com), adding 374 KiB and 150 ms of main-thread time.

5 images could be 90 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

2 long tasks block the main thread while loading, the longest for 73 ms. During a long task the page ignores taps.

About 47 KiB of JavaScript is downloaded but never used on this page.

About 27 KiB of CSS is downloaded but never applied on this page.

6 files are served with short cache lifetimes, so returning visitors download them again (17 KiB).

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Visually, the page fills in at 6.2 s (Speed Index). Good is under 3.4 s.

Your largest element takes 4.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

Real visitors wait 2.7 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 1.6 s to 2.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors see the first content after 2.1 s (75th percentile). Good is under 1.8 s.

The page becomes fully interactive after 6.4 s. Good is under 3.8 s.

3 images have no width and height attributes, so the layout jumps as each one loads.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 130 ms to 171 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.2 MB in 277 requests on a phone: other files 803 KiB (105), images 568 KiB (21) and scripts 532 KiB (105). Under 2 MB keeps phones on slow connections fast.

jA_Solar_High_Efficiency_Panel_Durable_Performance_Extended_ is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

1 image (47 KiB) is JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

By the Sustainable Web Design model, a visit to your homepage emits about 0.62 g of CO₂e: 74.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 element use ARIA attributes their role does not allow, which confuses screen readers.

Certain ARIA roles must contain particular children: 1 element on the page fails this check, rated critical by axe-core.

ARIA attributes must conform to valid values: 1 element on the page fails this check, rated critical by axe-core.

8 elements hidden from screen readers can still receive keyboard focus.

ARIA input fields must have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

Interactive controls must not be nested: 1 element on the page fails this check, rated serious by axe-core.

1 tap target is too small or too close together to hit reliably with a finger.

All page content should be contained by landmarks: 13 elements on the page fail this check, rated moderate by axe-core.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

2 form fields have no label, so screen readers announce an empty box and autofill guesses.

Elements marked as presentational should be consistently ignored: 1 element on the page fails this check, rated minor by axe-core.

Headings skip levels (h2 → h5), which makes the page harder to scan with a screen reader.

Your meta description is 197 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 237 pages on voltaconsolar.eu and 7 external pages.

Your Organization JSON-LD is missing logo, description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

Your homepage links to https://voltaconsolar.eu/collections/vendors, which answers with an error. Visitors hit a dead end and search engines drop it.

23 of 69 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

Social proof on the homepage: 2 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.
