Factors that Affect Solar Panel Costs in Northlake
The cost of installing a solar system in Northlake can vary by more than $10,000 from home to home. Your actual cost is determined by several factors. The biggest one is your system size, and other factors include the equipment you choose, financing options and the solar installer you choose.
Solar Equipment
One of the most significant factors to consider when it comes to the cost of installing solar panels is the size of the solar system, which is measured in kilowatts (kW). The more power your household uses, the larger your system will likely need to be. You can expect to spend around $3,760 per kilowatt in Northlake.The brand and kind of equipment you choose for your solar system can increase or decrease the price quite significantly. If you prefer a brand name like Tesla or SunPower, these often come at a higher price than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have limited roof space or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to greater savings over time. Plus, if you want additional equipment like an electric vehicle charger or solar batteries, this will also increase the cost.
Solar Financing Terms
If paying for a solar system in cash is difficult, solar loans are an affordable route because they lower your upfront costs and let you pay for your system over a term of, on average, between five and seven years.When considering your overall cost, you should also calculate the interest you’ll pay if you opt for a solar loan. Also, paying more on your down payment can lower the total interest paid over time.
Solar Panel Installation Company
The solar installation company you pick will impact your total cost to make the switch to solar . Different companies will charge different amounts for the equipment and labor.You may come across national solar installers that have lower prices due to their bigger brand name and access to bulk equipment prices, or you might see small, local installation companies offering deals or promotions to compete with those major players.

How to Save on Solar Panels
Since the type of solar panels and the installation company you choose has an impact on your costs and your system’s efficiency, production, and durability, it’s important to select the right ones for you. Here are some things to keep in mind to help with your decision:

- Reputation: Your solar installer should have a solid reputation as a company and have verifiable expertise in the field. Two 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 good reviews from past customers.
- Contract: Read the contract terms carefully to make sure you understand the overall cost, completion timeline incentives and warranties.
- Warranty: An all-inclusive, 25-year warranty can help keep your solar panel system running smoothly and save you money on part replacement and repairs.
