Our pre-design services help ensure your project's profitability early in the development process

LCOE Forecast Modeling

LCOE forecast modeling helps you analyze technology and project cost options before settling on a particular project configuration. Our process includes comparing LCOE and associated capital costs across different project technology types. The typical deliverable for this service is a brief report detailing which technology options are best suited to your project.

Project Design Optimization

Fundamentally, design optimization is the process of matching a project site with the right combination and placement of modules, inverters and racking and BOS. We begin by considering factors like site size and topography, available irradiance, and PPA structure where applicable. Based on these factors, we help you understand the range of relevant design options, the costs and benefits associated with each option, and provide actionable advice on which technology choices are optimal for your project.

Performance Modeling

Performance modeling provides you—whether you are a developer, EPC, or financier—with the right energy production number to plug into a project’s financial model. Our expert modelers provide clients with accurate and bankable energy forecast models for a wide range of site locations, climates, irradiance levels, and projects system configurations.

Site Services

When you engage our support siting your project, you simplify and streamline your project due diligence process. On your behalf, we identify the appropriate siting scope activities in order to control your project design and engineering costs. On your behalf, we manage the execution of various studies required to define and optimize site civil design including geotechnical studies, pile pull tests, and corrosion analyses.

SD+E offers turnkey design services for our commercial and utility scale projects. This reduces headaches for us and simplifies our design and approval process. We know that with SD+E, important design decisions are weighed with the whole project in mind.

Low Voltage Electrical Engineering

Our low voltage electrical engineers design the electrical system for your project from the modules to the grid (for net-metered projects) or from the modules to the inverter (for medium and high voltage projects). We draft multiple design scenarios for your team to compare and contrast in order to settle on a design that reduces capital cost and increases system energy output. In addition, our electrical engineering outputs include system grounding and system configurations that optimize the inverter’s loading to extract the most energy from your photovoltaic system.

Medium Voltage Electrical Engineering

Medium Voltage engineering is essentially what must happen to tie any power generation system to the grid. Our medium voltage electrical engineers design the wire and conduits needed to collect AC power after it is inverted and interface with the utility to make sure the grid protection design complies with NEC code and the utility’s standards. With over 20 years of experience designing utilty-scale PV systems, our engineers understand the protection schemes that properly isolate the system from the power grid and can work with utilities to optimize capital investment and code compliance.

Civil Engineering

Civil designs must comply with environmental permits and local codes and standards. Our engineers interface with civil surveyors and permit agencies to ensure a compliant design and to generate the civil details needed for ground mount project sites such as access roads, grading, erosion control and fencing.

Structural Engineering

Structural engineering includes creating a design that considers the all of site’s study inputs like the geotechnical and corrosion reports and the specific site conditions like wind loads and surrounding structures or terrain. This includes confirming a roof’s ability to support a solar array for rooftop projects and the foundation/ground’s capability to support a solar array for a ground-mounted project. Our experienced structural engineers expertly design code compliant and safe systems while considering install efficiency and capital costs.

Design Sets

The drawing set is the end product of the design and engineering process. A well-designed set reduces risk for the owner because the scope to the subcontractors is conveyed cleanly and accurately, thus the subcontractor can accurately bid the project without building in extra costs to protect their budget. Our sets are code compliant drawings sets that include all civil, structural, electrical and mechanical details required to plan and build the solar project as well as any supporting documents for permit approval and use during construction. Clients can influence the design package to reflect conditions and design approaches that are unique to their own projects like special wiring methods, communications equipment and site layout planning.
