Components Of A Solar Site Survey Checklist

By incorporating some considerations into your solar site surveys, solar installers can make informed decisions and provide accurate assessments of the suitability of a location for solar power installations. Here's a breakdown of all the components:

1. Local Climate

Average sunlight: Measure the amount of sunlight the location receives throughout the year. Tools like solar maps can help provide this information.

Average temperatures: Consider temperature variations and extremes, as they can affect solar panel efficiency and lifespan.

2. Site Assessment

• Size of the site: Evaluate the available space for installing the solar energy system. Larger sites may accommodate larger systems.

• Orientation: Determine the optimal orientation of solar panels based on the site's geography. South-facing solar installations generally receive the most sunlight.

• Shading: Identify potential sources of shading, such as trees or nearby buildings, as they can significantly impact azimuth solar exposure and therefore energy production.

• Availability of water and electricity: Ensure that the installation site has access to necessary resources for maintenance and operation.

3. Performance Evaluation

Assess the solar system's performance based on the collected data on the site survey form. Use software tools or models to estimate energy production.

Consider local regulations and permitting requirements, as they can impact the feasibility and timeline of the installation.

Also, evaluate the economic viability, including the cost of installation, potential savings, and available incentives or rebates.

4. Environmental Impact

Assess the environmental impact of the installation. Consider factors such as land use, potential disruption to local ecosystems, and disposal/recycling of materials.

5. Financial Considerations

Evaluate the return on investment (ROI) and payback period to determine the project's economic viability.

Solar Site Survey Report Requirements and Format

A solar site survey is an essential step in the process of planning and designing a solar energy system. It involves collecting data and analyzing various factors to determine the feasibility, efficiency, and overall success of a solar installation at a specific location.
