Real installs. Real numbers. Real savings.
Every case study below is a real Djuka customer, real Trustpilot quote, and real install spec, verified with the customer where possible.
Our case studies are not stock photos and round numbers. Each one is a real Djuka install, with the actual system specification, the customer’s own words, and a verified first-year saving figure. We are MCS-certified and NAPIT-registered, and we hold a 4.9-star rating across 82+ Trustpilot reviews, so the proof of how we work is public, not just promised. Where a saving is quoted here, it has been checked with the customer.

What we install
What our installs typically include.
- Solar PV. MCS-certified rooftop panels sized to your roof and usage, the core of most installs.
- Battery storage. Tesla Powerwall, EcoFlow and others, storing daytime generation for the evening peak.
- EV chargers. Home charge points that can draw from your solar so the car tops up on your own power.
- Commercial solar. Rooftop and ground arrays for Midlands businesses, with payback projections.
- Domestic electrical work. Consumer-unit upgrades, rewires and fault-finding, often alongside a solar install.

FAQs
Common questions.
How much can I save with solar in the Midlands?
It depends on your roof, your usage and your tariff, but the installs in these case studies saved their owners in the region of £1,150 to £1,200 in the first year. Adding a battery to store daytime generation for the evening typically increases that. Savings estimates are based on typical usage and current energy prices, and actual savings vary.
Are your case study savings figures guaranteed?
No. The figures are real and verified with the customer where possible, but they reflect those specific homes, systems and usage patterns. Your own savings depend on your property and energy use, which is why every quote we give is modelled for your address rather than a generic average.
Can I see installs near me?
Very likely. We install across Redditch and the wider Midlands, including Worcestershire, Warwickshire and the West Midlands. Tell us your postcode and we can talk through the kind of system that suits homes in your area.
How do I get a quote like the ones in these case studies?
Send us your postcode and a few details and we will come back with a free, written, itemised quote with no hidden costs. Solar quotes do not need a home visit at the quote stage; we can work from your postcode and a few photos.
