Solar Energy Consultants

Our ability to flex our renewables expertise and provide bespoke solar energy solutions means we can provide end-to-end solar consultancy and engineering for every aspect of a project, supporting you on feasibility/yield assessment, regulatory obligations, grid connection and environmental planning advice.

We can add multi-disciplinary value at every stage with electrical, mechanical and civil design solutions in addition to environmental and geotechnical consultancy. And with a wide network of partners, as well as global energy skills hubs across the Sweco group, we can also connect the right technology, suppliers and contractors for each specific business case.

With industry-leading skills, sector experience and solar energy consultancy portfolio we can support every aspect of a solar energy project, including consideration of regulatory sensitivities, grid connections, and environmental planning advice.

Feasibility, yield assessment & project investment appraisal

Investors and developers often require professional assessment and reporting of uncertainties related to the energy estimation and associated solar and meteorological data inputs. Our experienced consenting and environmental specialists provide relationship building with relevant planning authorities, statutory consultees and the local community, robust EIA reporting and management of consenting, licensing and permitting risks through project stages.

Sweco’s assessment tools are based on knowledge and leading-edge assessment tools derived from our long-term association with leading photovoltaics laboratories. Our unique capabilities and experience leads developers and investors globally to turn to us for reliable and independent assessment of long-term energy yield and related uncertainties.

Solar engineering & services grid connection consultancy

Grid connection is one of the key components to a successful solar project. Our experts can guide you throughout the solar PV system design to the grid integration process and offer an independent and flexible approach to enable successful delivery at every phase of the project.

From the early stages of site selection and feasibility, through to the project management of the construction phase, up to the project commissioning stage, we are here to help.

Multi-disciplinary support

With international skills hubs and proven multi-disciplinary collaboration in all sectors – from advisory & planning and infrastructure development to design implementation – Sweco can also advise on and review the electrical, and civil design of solar power projects, utilising a risk and cost-based approach from renewable power generation to energy storage and energy systems distribution.

Planning and permitting

Our specialists work closely with planning authorities, statutory consultees and the local community. We provide EIA reporting and management of consenting, licensing and permitting risks throughout the project lifecycle.
