Frequently asked questions
How long is the typical wait for an install with Jonstar Sustainable Technologies Ltd?
Lead times for Leicestershire renewables installers swing seasonally — late spring and early summer are peak demand. Ask Jonstar Sustainable Technologies Ltd directly for current scheduling once you've got a written quote. Plan for 4–12 weeks from deposit to install on a typical residential project; complex roofs or DNO upgrades can extend that.
What warranty does Jonstar Sustainable Technologies Ltd typically offer?
UK solar workmanship warranties commonly run 5–10 years; panel performance warranties 25 years; inverter warranties 5–12 years. Ask Jonstar Sustainable Technologies Ltd 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).
Is solar still worth it in Leicester given the climate?
Leicester gets enough annual sunlight for a typical 4 kW domestic system to produce roughly 3,200–3,800 kWh/year. Payback periods are typically 8–11 years at current electricity prices. Ask Jonstar Sustainable Technologies Ltd for site-specific yield modelling based on your roof orientation, pitch and shading.
How many Google reviews does Jonstar Sustainable Technologies Ltd have?
Review volume is limited at present. Ask Jonstar Sustainable Technologies Ltd for two or three customer references from their last 6 months of work; reputable installers will provide them. A small review count isn't disqualifying for a newer firm, but you should expect to see recent project photos.
Does Jonstar Sustainable Technologies Ltd handle Smart Export Guarantee (SEG) registration?
SEG registration is usually handled by your electricity supplier rather than your installer, but Jonstar Sustainable Technologies Ltd should provide the MCS certificate and inverter performance data your supplier will request. Ask Jonstar Sustainable Technologies Ltd whether they walk customers through the SEG paperwork as part of handover.
