titansolar.de website review

59 files are served with short cache lifetimes, so returning visitors download them again (404 KiB).

Your mobile performance score is 72. Pages that score under 90 lose visitors before the first paint.

About 103 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 460 ms faster on a phone.

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 550 ms.

8 third-party services load with your homepage (Shopify, adcell.com and ymq.cool and others), adding 1.1 MB and 259 ms of main-thread time.

The page has 2,456 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Shopify costs a phone 105 ms of main-thread work and 1,022 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.

Polyfills for old browsers add 45 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 200 ms faster on a phone.

8 images could be 228 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

4 long tasks block the main thread while loading, the longest for 110 ms. During a long task the page ignores taps.

11 KiB could be saved by minifying JavaScript.

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.

Your largest element takes 7.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Art. 5421 - 14Kw Titan Solar Mars Hybrid Inverter Wifi mit …”.

The page becomes fully interactive after 7.4 s. Good is under 3.8 s.

Visually, the page fills in at 4.6 s (Speed Index). Good is under 3.4 s.

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

1 image is downloaded at several times the size a phone draws it, for example Electricalservice_1_-12.jpg at 1,080 px wide, shown at 175 px. Resized copies would save about 69 KiB.

6 images (292 KiB) are 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 0.47 g of CO₂e: 56.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

12 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

4 tap targets are too small or too close together to hit reliably with a finger.

Heading levels should only increase by one: 1 element on the page fails this check, rated moderate by axe-core.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

1 form field has no label, so screen readers announce an empty box and autofill guesses.

Your title is 89 characters, so Google will cut it off around 60: “Titan Solar - Spezialist für PV Speichersysteme - auch zum Nachrüsten! – Titan Solar GmbH”.

Your meta description is 298 characters; Google truncates after about 160, so the end of your pitch is cut.

Your <h1> is empty.

The homepage links to 64 pages on titansolar.de and 2 external pages.

There is no https://titansolar.de/llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

https://titansolar.de/collections/balkonkraftwerke-und-zubehoer has no meta description, so Google writes the search snippet from whatever text it finds.

https://titansolar.de/collections/sets-mit-felicity-speicher, https://titansolar.de/collections/hochvoltspeicher, https://titansolar.de/collections/balkonkraftwerke-und-zubehoer, https://titansolar.de/collections/sets-mit-chisage-speicher, https://titansolar.de/collections/zubehor-und-gadgets and https://titansolar.de/pages/support and 2 others took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 38 found) and read each the way a search engine does.

4 errors were logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 404 ()”.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

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

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

The homepage shows no opening hours. If customers visit or call, show when.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

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

The homepage carries about 809 words of visible text.

No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.

Loading the homepage contacts 10 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
