Community Resources: How Can Local Solar Groups Support Off-Grid?

Resource Sharing and Collaboration

Local solar groups can facilitate the sharing of resources, such as equipment, tools, and expertise. This can include the reuse of solar panels, inverters, and mounting hardware, reducing waste and minimizing costs. For example, a group member may have a spare inverter that can be used for a new installation, or a member may have experience with a particular type of solar panel that can be shared with others. By pooling resources, local solar groups can help make off-grid installations more accessible and affordable.

State-Specific Solar Potential

The solar potential of a location is a critical factor in determining the feasibility of an off-grid installation. Different states have varying levels of solar irradiance, measured in peak sun hours (PSH) per year. For example, states like Hawaii and Arizona receive an average of 5-6 PSH per day, making them ideal locations for solar energy production. In contrast, states in the northern United States, such as Minnesota and New York, receive an average of 2-3 PSH per day. Local solar groups can help members optimize their installations by taking into account the specific solar potential of their location.

Training and Education

Local solar groups can provide training and education on solar installation techniques and best practices. This can include hands-on training sessions, online webinars, and workshops on topics such as system design, installation, and maintenance. For example, a group may host a workshop on how to properly size a solar array for a given load, or provide training on how to inspect and maintain solar panels. By providing education and training, local solar groups can help ensure that off-grid installations are safe, efficient, and effective.
