Spectrum Energy Systems Ltd

Spectrum Energy Systems Ltd is a solar maintenance and repair company based in Nottingham, established in 2011 by Charles Fletcher, who serves as Managing Director and Project Lead. Fletcher holds PRINCE2 certification and has 15 years of solar and wind energy experience. It has over 10 MW installed and serves the East Midlands, including Nottinghamshire, Derbyshire, Leicestershire, Lincolnshire, South Yorkshire, and Staffordshire. Services include solar panel installations, battery storage, and EV charging solutions for homes and businesses.

The company designs, installs, commissions, and maintains every system themselves without subcontracting, and provides a QANW Insurance-Backed Guarantee on every install. It is fully insured with £10M Employers’ Liability, £5M Public Liability, and £1M Professional Indemnity, underwritten by QBE UK. It has a sister company, Spectrum Wind Services Ltd. The company uses Solis or SolarEdge hybrid inverters, Fogstar and Pylontech batteries, and tier-1 panels from JA Solar, Aiko, or Longi. It provides all-in pricing including scaffolding, DNO application, MCS certification, and commissioning paperwork, and returns quotes within 48 hours.

Theatre and home projects alike appear in the feedback for Spectrum Energy Systems Ltd, with customers describing solar panel, battery storage and EV charger installations, including a major sustainability scheme that brought a venue close to covering its own energy needs. Charlie is named repeatedly, thanked for keeping in touch from the first enquiry through to aftercare and for answering queries promptly. Accounts tell of challenging property layouts being surveyed and resolved with a workable, cost-effective design after earlier attempts had stalled, and of minor faults being put right quickly, among them a component issue attended to at short notice.

Something that features in review after review is the tidiness of the finished work, the courtesy of the engineers and the clarity with which systems and their monitoring app were explained. Praise for competitive quotations recurs, along with references to specific equipment such as Aiko panels, an LG battery and a Solar Edge inverter. More than one customer describes the process as straightforward and the pricing as fair, and a recurring theme is the thoroughness of the advice offered before any work began, with Charlie on hand to answer questions.
