Solar photovoltaic (PV) design becomes harder to accommodate once roof layouts, service routes and construction sequences have already been fixed. Bringing solar expertise into the project earlier allows panel positions, electrical connections and installation dates to develop alongside the wider build programme.
SWH Electrical Solutions works with housing developers across the North East and Teesside on new-build solar projects ranging from individual homes to larger estates. Its service combines feasibility work, computer-aided design (CAD), installation planning and on-site coordination so solar forms part of the development strategy from the beginning.
Set the Solar Strategy at Plot Stage
The first decisions concern the plots themselves. Orientation, shading from neighbouring buildings or trees, roof structure and available panel area can all affect the generation potential of each home.
SWH Electrical Solutions carries out feasibility studies that examine these factors before the installation layout is finalised. Energy-yield projections can then provide developers with plot-specific information rather than relying on one assumption across an entire site.
That early assessment can also highlight where different house types require different solutions. A development may repeat several standard designs, yet orientation and surrounding shade can still change from plot to plot.
Turn Feasibility Data Into Buildable Designs
A viable solar concept still needs to be translated into drawings that roofing and electrical teams can use. SWH Electrical Solutions uses CAD capabilities to create panel layouts around the development’s roof structures and construction details.
The design stage can establish panel positions, cable routes and suitable locations for inverters and related equipment before internal finishes or external works restrict the available options. These details can also feed into Standard Assessment Procedure (SAP) calculations and the wider energy-performance planning for the development.
Developers can use the resulting information during design reviews, procurement and coordination meetings. Clear drawings and performance estimates give each discipline a defined solar requirement rather than leaving the installation team to resolve major design questions after arriving on site.
Reserve Roof and Service Space Before It Disappears
Roof space competes with vents, rooflights, chimneys and architectural features. Internal service areas may also need to accommodate electrical equipment, cable routes and possible battery storage alongside heating and utility systems.
Addressing these requirements early allows the architect, engineer and solar designer to work from the same layout. Panel placement can then be coordinated with structural details and other roof elements while cable routes can be incorporated into the build rather than added visibly after completion.
Early planning also supports a cleaner finished property. Equipment can be positioned with access, appearance and future servicing in mind while the design team still has room to make practical adjustments.
Fit Installation Into the Main Programme
Solar installation has direct dependencies on roofing, scaffolding, electrical work and site access. A delay or sequencing conflict in any of these areas can affect plots that are approaching completion.
Each SWH Electrical Solutions new-build project is overseen by a dedicated project manager who coordinates with other trades. The installer’s in-house electricians, roofers and scaffolders allow related stages to be planned together rather than managed through several disconnected contacts.
The programme can identify when roofs will be ready, when scaffolding is available and when electrical connections can be completed. This gives the developer a clearer route from design approval to commissioning while reducing avoidable return visits.
Manage Repeated Plots Without Assuming They Are Identical
Volume developments benefit from repeatable specifications, but repetition should still account for real differences across the site. The same house type may face another direction, experience different shading or require adjustments because of its position within the construction programme.
A coordinated solar package can establish standard components and working methods while retaining plot-level checks. This balance supports efficient delivery without treating every roof as though it has the same generation conditions.
SWH Electrical Solutions supports both individual properties and full estates. Its feasibility, design and project-management capabilities allow the solar scope to be organised around the size and structure of the development.
Plan Around the Future Homes Standard
The Future Homes Standard was published in March 2026 and is scheduled to come into force on 24 March 2027, followed by a one-year transitional period. New homes will require high levels of energy efficiency and low-carbon heating, with solar panels included for the majority of properties.
For developers, this increases the value of treating solar as a design-stage workstream. Roof orientation, generation capability and electrical integration can be considered alongside the wider energy strategy instead of being left until compliance information and construction drawings are nearly complete.
The precise solution still depends on the development and applicable regulatory route. SWH Electrical Solutions designs new-build installations around UK building regulations and SAP requirements while coordinating the solar work with the project’s technical and programme needs.
Include Battery Storage Where It Supports the Brief
Battery storage may form part of the energy plan when the development specification calls for greater use of electricity generated on site. Including it during design allows storage location, electrical capacity, cable routes and access requirements to be assessed alongside the solar system.
This is more effective than selecting a battery after the main electrical design has been completed. The project team can consider how solar generation, household demand and any low-carbon heating or vehicle-charging provision will interact within the finished home.
SWH Electrical Solutions provides solar PV and battery-storage services within the same renewable-energy offering. That combined capability allows developers to explore an integrated specification where it suits the project rather than coordinating the two technologies separately.
Prepare Commissioning and Handover Early
A new-build solar project continues beyond mounting panels on the roof. Testing, commissioning, warranties and handover information all need to be ready as plots move towards completion.
SWH Electrical Solutions includes product and installation warranty protection within its new-build service and offers post-build maintenance programmes and performance monitoring. Planning these elements before handover gives developers a defined route for transferring system information and ongoing support to the homeowner.
Documentation should be organised around the individual property so the new owner can understand the installed system. Clear handover information also gives sales, customer-care and maintenance teams a consistent reference after completion.
Bring Solar Expertise Into the Project Before Designs Harden
Early solar planning gives developers more control over roof layouts, electrical routes, trade sequencing and handover preparation. It also allows feasibility findings and energy projections to influence the development while meaningful design changes are still possible.
SWH Electrical Solutions provides new-build solar feasibility, CAD-supported design, project management, installation and ongoing support across the North East and Teesside. Arrange a feasibility study or request a customised proposal to bring the solar scope into your next development from the planning stage.
Frequently Asked Questions
When should a solar installer join a new-build project?
A solar installer should ideally become involved while roof layouts, plot orientation and electrical plans are still being developed. Early input gives the project team more opportunity to coordinate panel placement, cable routes and construction sequencing.
Can SWH Electrical Solutions work across an entire housing estate?
Yes. SWH Electrical Solutions supports projects ranging from individual new homes to full estates across the North East and Teesside. Its service includes feasibility studies, design, installation and project management.
What does a new-build solar feasibility study assess?
The assessment can examine plot orientation, shading, roof structure, panel placement and projected energy yield. These findings help determine how the solar design should vary across different plots or house types.
Does SWH Electrical Solutions coordinate with other site trades?
Yes. A dedicated project manager coordinates the solar work with other trades, while SWH Electrical Solutions’ in-house electricians, roofers and scaffolders support delivery across related installation stages.
Can battery storage be included in a new-build solar design?
Yes. SWH Electrical Solutions provides solar PV and battery-storage solutions, allowing both technologies to be considered during the development’s electrical and energy planning.
