Solar System Design and Shadow Analysis

Does a 15% increase in energy output from a solar installation sound appealing to you? Keep reading.

Before initiating the development of a solar installation, there are numerous factors that the developer must consider in order to ensure that the energy output is maximized. Not only this, but not all rooftops are capable of housing a solar installation, and therefore a careful analysis of the building must be conducted in order to ensure that the installation is feasible. Exactus Energy specializes in alternative energy design, and the use of our solar consulting services can result to a 15% increase in solar output from a given installation!

Evaluation of Building Sites

The most common location for the installation of solar panels is on rooftops; however, if a rooftop area is not available, panel modules can be pole-mounted, ground-mounted, wall-mounted or installed as part of a shade structure. When evaluating a building site as part of our solar design process, we primarily evaluate the underlying roof structure, required area, and orientation of the panels; then we optimize accordingly.

Here in Canada and the USA, conventional engineering wisdom dictates that solar panels are ideally oriented towards true south. However, this is not a hard-set rule as local weather patterns can also influence the ideal orientation panels. Exactus Energy has years of experience with design, and can help our clients determine the optimal orientation of their installation according to a variety of different factors.

The availability of roof space will also dictate the design of your renewable energy system, as different locations and panel types will require different amounts of space in order to produce equivalent amounts of power. Exactus Energy works with our clients to optimize the solar installation according to the available space, ensuring that all projects generate the highest possible ROI.

When it comes to the underlying structure supporting the solar installation, it is critical that no mistakes are made! We at Exactus Energy will physically inspect your proposed installation site as part of our solar solutions design process to ensure that it can support the added load of solar panels.

Sun Shadow Analysis

Well-designed solar installations need clear and unobstructed access to the sun’s rays for at least 6 hours per day in order to optimize their efficiency. Even small shadows can significantly reduce the power output of a solar module.

Shading from the building itself also must be accounted for. Exactus Energy has the technology to simulate where shadows will occur at any time of day or year and any geographic location, to make sure that the selected installation site has the greatest sunlight accessibility all year long.
