This policy explains how SOLARFIELD uses cookies and similar technologies on this website (including the solar ROI / cost calculator), and how you can control them. In this policy, “cookies” also covers similar technologies such as analytics tags and browser local storage.
Cookies are small text files placed on your device when you visit a website. They are widely used to make sites work and to provide information to site owners. Some cookies are essential for the site to operate; others are optional and are only used with your consent.
When you first visit, we show a cookie banner. Necessary cookies are always active because the site cannot function without them. Analytics cookies are only set after you opt in — nothing is loaded before you choose. You can accept all, reject all, or manage your choice.
You can change or withdraw your consent at any time using the “Cookie settings” button at the bottom-left of every page. Withdrawing consent stops further use of analytics cookies.
Required for the website to function, including remembering your cookie choices. These are not used for tracking or advertising and do not require consent.

Google Tag Manager may also be used to manage these tags; it does not set its own cookies.
When you consent, the analytics tools above are operated by Google and Microsoft, who act as recipients of the related data. They may process data outside the UK/EEA under appropriate safeguards. Their own notices provide full detail: Google and Microsoft Clarity.
In addition to our banner, most browsers let you block or delete cookies through their settings. Blocking all cookies may affect how this and other sites work.
