Solar Panel Installation in Derby
Generate your own clean electricity with a properly designed solar PV system, installed by qualified electricians and backed by a dedicated office team from survey to commissioning.
Solar Panel Installation You Can Rely On in Derby
Solar panels are one of the most effective ways to take control of rising energy costs, but a system only performs well when it is correctly specified for the property and installed to electrical standards. As NICEIC Approved Contractors, we design and install solar PV systems using high-efficiency panels from AIKO, Longi, and Sigenergy, and we handle the full electrical integration so your installation is safe, certified, and ready to pair with battery storage or an EV charger.
“Give a Shit & Do The Right Thing” — our standard for every single customer emergency.
What Makes Up a Solar PV System
A solar installation is more than panels on a roof. We specify every component to work together, from the modules that capture daylight to the inverter that makes it usable in your home.
Every system we install is fully tested and certified, with generation monitoring set up so you can see exactly what your panels produce.
Solar PV Panels
High-efficiency monocrystalline modules from AIKO, Longi, and Sigenergy, selected for output, durability, and warranty performance on British roofs.
Inverter
A string inverter or hybrid inverter converts the direct current from your panels into usable alternating current, with monitoring so you can see generation in real time.
Mounting System
A weatherproof roof-fixing system secures the panels to your roof structure with correct spacing for ventilation and drainage, keeping the roof weathertight.
Generation Monitoring
An app or online portal shows live generation and consumption, so you can track performance and spot any drop in output quickly.
Is Your Home Suitable for Solar?
Not every roof is the same. During the survey we assess these four factors honestly and only recommend a system if it will genuinely perform for your property.
Roof Orientation
South-facing roofs generate the most energy, but east or west-facing roofs still produce a strong, worthwhile yield. We model expected generation before you commit.
Roof Condition
Your roof should be in sound condition with enough unshaded area for the panel array. We assess pitch, structure, and any shading from chimneys or neighbouring buildings.
Energy Usage
The right system size depends on how much electricity you use and when. Homes using more power during daylight hours see the fastest return on a solar investment.
Future-Proofing
If you plan to add a battery, an EV charger, or a heat pump, we size the system and inverter to integrate cleanly so you can expand without replacing equipment.
Your Solar System Options
From a straightforward rooftop array to a battery-paired or retrofitted setup, we design the system that fits how you use energy and where you want to take it next.
Rooftop Solar PV
Most Derby homes and businesses
Panels mounted on your existing roof using a weatherproof fixing system. This is the most common and cost-effective installation, suitable for pitched and some flat roofs.
Solar With Battery Storage
Homes wanting power after dark
Pairing your panels with a Sigenergy or Sunsynk battery stores surplus daytime generation for use in the evening, increasing self-consumption and protecting against power cuts.
Retrofit to Existing PV
Properties with panels already fitted
If you already have solar installed, we can add battery storage, upgrade your inverter, or integrate an EV charger so you get more value from your existing generation.
We find the right solution for your property, not just the quickest fix. Our office team will talk you through the options and arrange a survey before any work begins.
