Frequently asked questions
Does Greenstar Solar handle Smart Export Guarantee (SEG) registration?
SEG registration is usually handled by your electricity supplier rather than your installer, but Greenstar Solar should provide the MCS certificate and inverter performance data your supplier will request. Ask Greenstar Solar whether they walk customers through the SEG paperwork as part of handover.
Is Greenstar Solar MCS Certified for solar PV?
MCS certification is the industry standard for UK solar installers. Check the live MCS register at mcscertified.com — search by company name. If Greenstar Solar is currently MCS Certified, their name and certificate number will appear. If not listed, ask why.
What warranty does Greenstar Solar typically offer?
UK solar workmanship warranties commonly run 5–10 years; panel performance warranties 25 years; inverter warranties 5–12 years. Ask Greenstar Solar specifically what's covered, who underwrites it, and what happens if they go out of business (an MCS Insurance Backed Guarantee — IBG — covers this scenario).
Does Greenstar Solar install battery storage as well as solar PV?
Yes — Greenstar Solar's listed services include battery storage installation. Common UK brands include Tesla Powerwall, GivEnergy, BYD, Solax and Fox ESS. Ask which brands Greenstar Solar typically specs and whether they're certified installers for that brand.
Are there other solar installers in Portsmouth I should compare?
Yes — three quotes is the UK standard. Use EnergyRanked's Portsmouth filter to compare Greenstar Solar against other local installers on rating, review count, and accreditation. Don't just chase the cheapest quote; compare warranty terms and brand specs side-by-side.
