Installing & Planning Solar Power Buildings

Conduct a Site Assessment

Whether residential, commercial or industrial, solar power systems offer buildings an efficiency and reliability that traditional systems cannot. The first step in the process is conducting a site assessment. Hire an expert in the field. This expert will provide a basic review of needs and evaluate the best resources. He will also provide a cost estimate. It is important for this person to be an independent, third-party consultant; that is, she should not have any affiliation with the installer. This is the best way to ensure a fair assessment.

Find a Reputable Installer

There are many full-service installers in the solar industry. Narrow the field by looking for a contractor who can provide a full-service package from design to equipment to installation and maintenance services. The contractor should be able to help with zoning and building codes of the county, and most will help to get the permit. Certain projects may also qualify for a grant or tax credit, so be sure the contractor is local and knows both the municipal and federal tax incentives associated. For a list of incentives, see Resources.

The Cost Estimate

Try to get at least three estimates and compare costs. If one varies greatly from another, understand the reasons why. It is OK to ask for specific details on the terms of service. Also, do not be afraid to share cost estimates. More than likely contractors will either reduce costs or explain why they cost more. A cost estimate should include installation, hardware, connecting to the utility grid, travel, shipping and sales tax. The lowest price is not always the best value.
