Factors that Affect Solar Panel Costs in Lawrenceville

There are many criteria that can play into your solar system installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that performs the installation.

Solar Equipment

The cost of solar panel systems varies by thousands of dollars due to a variety of factors. One of the notable factors is the system size, which is measured in kilowatts (kW). Solar power systems that have greater efficiency or power generation need better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $2,770. There are several different solar panel brands and the one you pick also affects the cost. Generally speaking, the brands that are more efficient tend to also cost more. Plus, the type of equipment you want to install can affect your total cost. If you just need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

Solar panels can save you money on energy bills over time, but they can also be a significant investment. That's why many Lawrenceville homeowners decide to finance their solar panel systems to offset upfront costs. However, the interest on solar loans also increases your total costs, so it's important to take that into consideration as well. You can always bring down the total you pay in interest and sometimes even your APR by putting more money down.

Solar Panel Installation Company

The solar installer you opt for to handle your switch to solar energy can have an effect on your total costs. There are about 3 solar panel companies operating in Lawrenceville, and each can charge varying amounts for labor and equipment. Larger national companies typically have lower costs, but some local companies compete with them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or additional services like electric vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels

There are many solar installers to choose from, all of which offer different warranties, solar panel models and price points. To help you pick the right company for you, here are some tips to keep in mind:

  • Reputation: Your solar installer should have a good reputation as a company and have verifiable expertise in the field. A couple of ways to check this are to look for whether a company has technicians that hold a certification from the North American Board of Certified Energy Practitioners (NABCEP) and if it has satisfied reviews from past customers.
  • Installation Process: Make sure you're aligned with the installer with regard to how the installation process will go and what you need to do before your solar panels are installed, such as repairing your electrical system or roof.
  • Contract: Review the contract terms carefully to make sure you understand the total cost, project completion timeline rebates and warranties.
  • Solar Panel Brands: Different companies offer various brands and models of panels. If you prefer a specific brand, make sure the solar company you're considering has it.
