See the proofWhat makes solar different in London
London homes are a mix of Victorian terraces, 1930s semis, town houses, and newer infill developments. Roof shapes vary widely, and shading can change house by house. We design each system around these local patterns so it works properly for your property.
- Victorian terraces often suit optimisers because of chimneys, roof angles, and mixed shading.
- North London homes with mature trees often benefit from panel level optimisation to stabilise winter performance.
- Converted lofts in South London often create mixed pitch layouts that require careful inverter selection.
- West London flats and maisonettes often need specialist mounting for smaller roof areas.
- New builds in East London are typically ideal for battery ready systems because layouts are uniform.
Optimisers and Micro Inverters Explained for London
Roof layouts in London often create uneven sunlight because of chimneys, trees, roof lights, and extensions. Optimisers and micro inverters allow each panel to work independently so the entire system does not slow when one panel is shaded.
Optimisers are ideal for mid level shading, mixed roof angles, and homes that have chimneys or loft conversions that cast shadows.
Micro inverters are best for complex roofs, or when homeowners want panel by panel control and increased resilience. They provide reliable monitoring and consistent output.
For simple, clear roofs facing one direction, a standard string inverter often gives the best value.

Battery Payback Guidance for London Homes
Battery systems have become the most common upgrade in London because many homes have higher evening usage. Batteries store excess solar generated during the day so you use more of your own energy and buy less from the grid.
Even if you have limited roof space, a battery can still reduce your bills through off peak charging. You charge the battery cheaply overnight and use it through the day.
Most London homes with an average sized system see the strongest payback when pairing solar with a battery because usage profiles match the way households live and work.
