Multiple physical factors dictate the long-term efficiency of your system:

• Orientation: South-facing surfaces typically collect the most steady sunlight throughout the day, optimizing energy yield.
• Pitch: The slope of your roof impacts how directly panels face the sun, which impacts the total annual energy generation.
• Shading: Nearby trees, chimneys, or neighboring structures can cause intermittent shading, which significantly degrades the performance of modern solar arrays.
• Structural Condition: Your roof must be in satisfactory enough condition to support the weight of the hardware for the expected 25 to 30 years of system life.

Before you sign a contract, ensure your installer provides a detailed report on these variables. An contractor who skips a comprehensive physical examination or depends solely on satellite imagery may overlook structural issues or shading patterns that could compromise your investment. Ask prospective installers to give a precise explanation of how your roof’s specific geometry affected their system design.

Ask for a copy of the site survey report to evaluate how different installers factor in shading and roof integrity in their design logic.

In comparison, a workmanship warranty guards you against flaws arising from the setup procedure, such as roof penetrations, mounting failures, or wiring errors. When assessing an installer, verify the following protection components:

Some installers differentiate themselves by offering price-match guarantees, which require you to provide a comparable written proposal from a competitor to trigger a price adjustment. Always ensure that the work guarantee is clearly defined in your contract, as this document determines your remedy if the system requires repairs due to improper mounting or defective electrical linkages shortly after the installation is finished.

Ask for a copy of the installer's workmanship warranty document to confirm the precise duration and specific conditions under which labor costs for repairs are covered.
