FAQ

Common questions

Should I use this form or book a diagnostic?

If you have a solar system fault, use the booking form — the remote diagnostic is free under our no-fix-no-fee policy. If you have a general question, a commercial enquiry, a partnership request, an installer-support enquiry, or you're not sure whether you need a diagnostic, use this contact form. We'll always point you in the right direction.

Do you charge to answer questions?

No. Asking questions is free. The free remote diagnostic itself is also free under our no-fix-no-fee policy — you only pay if we resolve your fault. We don't charge for initial advice, pre-purchase questions, or signposting to the right service.

How quickly will you respond?

Within 4 hours during business hours. Business hours are Monday–Friday 09:00–19:00; closed weekends. Messages received outside hours are read the next working morning. For urgent solar emergencies (no power, sparks, burning smells), call directly on 07944 877 329 or use the emergency repair service.

Where are you based and do you cover my area?

STS is based in Cudworth, Barnsley. On-site work covers Yorkshire and the East Midlands as standard, with extended coverage by arrangement. Remote diagnostics are available nationwide and don't depend on where you are — anywhere in the UK with internet access.

Can I call you instead of using the form?

Yes. Phone: 07944 877 329 during business hours. If we don't pick up immediately we're likely on another call or on-site — leave a voicemail with your name, system brand, and what's happening, and we'll call back the same business day.

Are you independent?

Yes. STS Solar Tech Support is an independent diagnostic and repair service. We are not affiliated with any inverter or battery manufacturer. We don't sell new solar systems. Independence means we tell you whether your existing system can be saved, not whether a sale is in our interest.

I'm an installer — can you help with technical support?

Yes. We offer remote installer technical support for working solar installers — engineer-to-engineer, confidential, from £75 per session. Use this form with 'Installer support' selected and we'll respond same day with availability.

Press, media, or partnership enquiries?

Use this form with 'Press / partnership' selected. We respond to genuine media and partnership enquiries within one business day. Please include the publication or organisation name and a brief description of what you'd like to discuss.
