Your solar questions
Most roofs are. South-facing is best, but east and west-facing roofs work well too, and we'll check for shading from trees, chimneys or neighbouring buildings. If your roof isn't a good fit, we'll tell you rather than sell you something that won't deliver.
It depends on the size of the system, which way your roof faces and any shading. As a rough guide, each kilowatt of panels on a good roof in our area produces around 850 to 1,000 kWh a year. Your Return on Investment Assessment shows the figure for your own roof.
Not a salesperson. If you decide to go ahead after your showroom visit, one of our team carries out the survey. On installation day you'll meet our electricians, along with the roofing and scaffolding teams we work with, and your project manager stays your single point of contact from start to finish.
Panels sit on aluminium rails fixed to the rafters with roof hooks that slip under your tiles or slates, so the roof stays watertight. Cables run neatly into the loft and down to the inverter. The layout is designed for your roof at the survey, so we know exactly where every panel goes.
Through the Smart Export Guarantee, your electricity supplier pays you for the power you send back to the grid. You'll need your MCS certificate, and we'll help you get set up. Grants for solar are limited for most homeowners, but if you might qualify for one, we'll point you in the right direction.
Getting the panels on the roof isn't the end of the job. If a question pops into your head six months later, about your app, your bills or adding a battery, ring us or drop into the showroom. You'll speak to people who answer the phone and know your system.
