Solar Panels in Cambridge
Cambridge represents the largest urban market in our core service area. The city's tech sector, university colleges, hospitals, and growing residential developments create enormous demand for solar panels, battery storage, and heat pumps. Cambridge receives excellent solar irradiance for England at approximately 1,040 kWh/m². The city's mix of Victorian terraces, modern developments, and commercial buildings all suit solar installation. Cambridge Biomedical Campus and the Science Park offer major commercial solar opportunities.

Get a quoteSmart Export Guarantee — Earn From Your Solar in Cambridge
The Smart Export Guarantee (SEG) requires energy suppliers to pay you for every unit of electricity you export to the grid. Available to all Cambridge homeowners with an MCS-certified solar installation, SEG adds £60–£300 per year in additional income. The best tariffs currently pay 5–15p/kWh (Octopus, E.ON Next, EDF). We register your system with your energy supplier as part of the installation.
How Solar Panel Installation Works in Cambridge
Free survey and roof assessment
We visit your Cambridge property to assess roof orientation, pitch, condition, available area, shading, and electrical connection point. We design your system and provide a detailed, fixed-price quote at no charge.
System design and paperwork
We handle all grid connection notifications (G99/G98), any required planning consent, and DNO applications on your behalf. Most systems are notified — not approved — meaning installation can proceed immediately.
Installation — typically 1–2 days
Our MCS-certified engineers mount the racking, install panels, run cable to the inverter location, and connect the system. We commission and test generation, export metering, and the monitoring app before leaving.
Smart Export Guarantee and monitoring setup
We register your system with your energy supplier for SEG payments and set up the monitoring app (Fox ESS, SolarEdge, or Huawei FusionSolar) so you can track generation and savings in real time.
Why Cambridge Is an Excellent Location for Solar
Cambridge receives 1,040+ kWh/m² — well above the UK average of ~900 kWh/m². The flat Fenland landscape north and east of the city means no horizon shading for most properties. East Anglia consistently records above-average sunshine hours compared to other parts of England, making Cambridge one of the best locations in the UK for solar energy generation.
