A practical checklist for comparing solar quotations on scope, equipment, warranties and assumptions.
Confirm the exact manufacturer and model for every major component. Check quantities, electrical ratings, compatibility and warranties. Establish whether the price includes VAT, delivery, mounting, protection, installation, certification, monitoring and additional electrical work. Ask what has been excluded and which site conditions may change the price. Generation, savings and backup-duration estimates should show the assumptions used. Compare complete scope and lifecycle support rather than choosing only on headline price.
