Service Introduction
A solar system assessment is the foundational step before any physical installation occurs. It involves a detailed, technical evaluation of a property to determine its physical and electrical suitability for solar energy generation. In Ontario, this assessment dictates system design, equipment selection, and overall project viability.
What the Service Involves
Professionals measure available roof or ground space, assess structural integrity, and analyze the property's main electrical service panel. Tools such as solar pathfinders are used to map shade obstacles throughout the year to calculate expected energy generation.
Suitable Applications
This is required for all new residential, commercial, rooftop, or ground-mounted projects to ensure safe and compliant system planning. No professional installation proceeds without a thorough prior assessment.
Planning Considerations
Focus is placed on current energy usage, local building codes, and identifying necessary preliminary upgrades, such as roof repairs or electrical panel replacements before solar can be introduced.
Equipment Considerations
Assessors determine which mounting hardware matches the roof type and which inverter topology best suits the site's shade profile to maximize energy harvest and meet grid compliance standards.
Installation Considerations
The data gathered informs the final installation blueprint, defining hardware layout, conduit pathways, connection points, and identifying potential hazards for the installation crew.
Maintenance Considerations
Initial assessments also plan for future maintenance access, ensuring panels are placed where they can be safely reached for cleaning or inspection without compromising safety.
Important Limitations
Assessments define constraints, such as structural weight limits, heavy shading that restricts system size, or utility limitations that dictate the maximum export capacity for the property.
FAQ
How long does an assessment take?
A physical site visit typically takes one to two hours, followed by technical design work off-site which can take several days to finalize into a proper proposal.
