Make & Model - Just like many products, solar panels come in a wide variety of makes and models. It's essential to pick a highly rated installer, given the brand preferences that installers may have. Higher grade makes and models typically result in an better long-term experience for the buyer.

Solar Panel Type - The standard in the industry is now monocrystalline panels, and rightly so. These panels are more expensive, yet they generate more energy. Many installers tend to work with panels constructed from this material.

Your Property - Each property and home has its own characteristics. Factors like trees, sloping terrain, or additional considerations can make the installation more challenging. Nowadays, most solar installers are able to leverage satellite images to evaluate your home and incorporate these factors for the preliminary cost estimate.

Labor Rates - Different companies offer different wages to their employees, and these costs are eventually passed on to the consumers. Businesses paying more to their employees typically garner higher reviews for their work and customer service.

Permitting & Interconnection - Local permitting and utility level interconnection fees change by area and will influence your final install price. Good local installers will build these figures into your preliminary estimates to avoid any surprises.
