Questions we’re asked

Do I need MCS certification for solar?

MCS certification is required to access the Smart Export Guarantee and some grants. SEG is MCS-certified, so we can provide the certificate.

Is a battery worth it?

It depends on when you use electricity and the tariff you are on. We model your usage and say honestly whether it pays back in your case.

Can solar be combined with an EV charger?

Yes. Solar-aware chargers can prioritise surplus generation, and we install them as a pair regularly.

Need it done by a date?

Tell us the deadline. We’ll tell you honestly whether we can hit it — and we usually can.
