DPR typically carries a Solar photovoltaic (PV) overshadowing assessment alongside daylight and sunlight studies at the pre-application stage. They use advanced simulation techniques on an accurate and detailed 3D site models to simulate the development’s impact on sunlight reaching neighboring solar panels throughout the year. This allows DPR teams to measure potential energy losses and consider mitigation options before designs are finalised.​

These assessments are increasingly expected by planning officers—especially in areas like London where solar adoption is being actively promoted. They also support compliance with environmental standards such as BREEAM, LEED, and the UK Net Zero Carbon Building Standard.​

Solar PV Overshadowing Assessments at the Right Stage

DPR supports developers by integrating solar overshadowing assessments into the early stages of the design and planning process. This approach helps to avoid costly delays as it allows developers to respond to neighbour concerns, satisfy planning officers, or mitigate potential impacts during the design phase—reducing the likelihood of objections later.​

Carrying out a solar assessment early in the design process doesn’t just prevent planning issues it can also enhance the sustainability credentials of your own development. By optimising the orientation and placement of solar panels, developers can boost long-term energy performance, reduce operational carbon, and appeal to eco-conscious buyers and tenants.​

PV Overshadowing Assessment forms part of the scope of the Daylight, Sunlight an Overshadowing review required as part of the planning application process. Using detailed 3D modelling and sunlight analysis, we help identify potential conflicts with neighbouring solar installations before they become planning obstacles.​
