Factors that Affect Solar Panel Costs in Lawrenceville

For many Lawrenceville homeowners, the decision to install a solar energy system comes down to cost. However, the range of solar installation costs can be quite wide in Lawrenceville, with typical prices between $20,000 to $40,000. There are a few factors that greatly influence the price you’ll pay, which we'll go over below.

Solar Equipment

The cost of solar panels varies by thousands of dollars due to a few different factors. One of the most significant factors is the system size, which is measured in kilowatts (kW). Solar power systems with higher 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 $3,760.Some solar brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer higher efficiency. In a city like Lawrenceville, where sunlight is relatively abundant, efficiency can quickly pay off. In addition, if you have a small roof or you don’t have a lot of space for your panels, higher efficiency options will be a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

If paying for solar panels in cash is out of reach, solar loans are an affordable option because they lower your upfront costs and let you pay for your system over five to seven years on average.You’ll have to consider the long-term cost of financing options, including the amount of interest you’ll pay over the length of the loan. If you can only get a high-interest loan, then your total can be hundreds or even thousands of dollars more than the principal cost. Making a larger down payment or finding a solar loan with a low interest rate could reduce your costs considerably.

Solar Panel Installation Company

The solar installation company you select will impact your total cost to go solar. Different companies will bill different amounts for the equipment and labor.The size of the company can sometimes play the most significant role in the cost. Larger national companies, like SunPro and Sunrun, often have lower pricing due to access to greater resources and better pricing. Smaller local companies might be more costly, but they generally have better customer service and more customization options, and the occasional sale or promotion can bring their pricing down to compete with bigger companies.

How to Save on Solar Panels

The solar panel company you go with will affect not only your overall costs, but also the types of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are a few important things you should keep in mind, including:

  • Reputation: Companies that have been in business for many years likely have a good reputation. This is important because it ensures that it will not only see your solar project through, but will also provide quality aftercare and customer support, such as part repairs and replacements.
  • Warranty: If you’re worried about the durability of your solar energy system, verifying that your company offers a 25-year, all-inclusive warranty can help put you at ease.
  • Solar Panel Brands: The type of solar panel you want plays a role in which company you should choose, since different companies provide different panels.
  • Contract: Before signing a contract with a solar company, make sure to look it over completely so you understand the terms. Also, ask questions if you’re not sure about some of the terms, such as what the warranty covers and if there are any guarantees about energy production.
