Factors that Affect Solar Panel Costs in Marietta
There are several criteria that can play into your installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar system.
Solar Equipment
The cost of solar panel systems varies by thousands of dollars due to a variety of factors. One of the major factors is the system size, which is measured in kilowatts (kW). Solar power systems with higher efficiency or power production require better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $3,410.The brand and kind of equipment you get for your solar system can raise or lower the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these often have a higher price tag than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have a small roof or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to more savings over time. Also, if you want extra equipment like an electric vehicle charger or solar batteries, this will also increase the cost.
Solar Financing Terms
Most solar installers in Marietta have solar loans, which reduce the initial cost of installing solar.When figuring out your overall cost, you should also calculate the interest you’ll pay if you choose to go with a solar loan. Also, paying more on your down payment can lower the total interest paid over time.
Solar Panel Installation Company
A final consideration when trying to evaluate the cost of solar for your home or business in Marietta is the company you get to install your solar system. As with choosing a company to install new cabinets, for example, there’s no shortage of solar installers that provide a range of services at different price points.Some companies only sell high-efficiency and high-priced products — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come at a higher cost. It’s best to do some research and go with the company that has the products, warranties and services you’re looking for and also is within your budget.

How to Save on Solar Panels
Since the kind of solar panels and the company you choose significantly affects your costs and your system’s durability and efficiency, it’s important to select the right ones for you. Here are some tips to keep in mind to help with your decision:
- Contract: Before you sign a contract with a solar company, make sure you read it through fully so you understand the terms. Also, ask questions if you’re unsure about some of the terms, such as what to do if a part breaks or malfunctions and what services you can expect from them.
- Solar Panel Brands: The brand of solar panel you’d like to get plays a part in which company you should opt for, since different companies offer different panels.
- Reputation: Your solar installer should have a sound reputation as a company and have proven 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 satisfied reviews from past customers.
- Warranty: If you care about the durability of your solar panels, checking if your company offers a 25-year, all-inclusive warranty can help put you at ease.
