Factors that Affect Solar Panel Costs in Cranbury
Cost is typically one of the most important factors for homeowners considering investing in solar. There are a few major factors that determine your overall cost in Cranbury: solar equipment and system size, financing options and the solar installation company you choose. We’ll cover each of these briefly below.
Solar Equipment
The cost of solar panels 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 greater efficiency or power generation need 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 $3,530.The brand and type 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 greater savings over time. Also, if you want add-ons like an electric vehicle charger or solar batteries, this will also increase the cost.
Solar Financing Terms
Most solar installers in Cranbury provide solar loans, which reduce your upfront costs of installing solar panels.You’ll have to consider the long-term cost of financing options, including the total 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 above the equipment and labor cost. Making a larger down payment or finding a solar loan with a low APR could reduce your costs considerably.
Solar Panel Installation Company
The solar panel installer you choose will impact your total cost to make the switch to solar power. Different companies will charge different amounts for the equipment and labor.The size of the company can sometimes play the most considerable role in the installation costs. Larger national companies, like SunPro and Sunrun, often have lower prices due to access to more resources and bulk pricing. Smaller local companies might be more costly, but they can sometimes have better customer service and more customization options, and the occasional sale or discount can bring their pricing down to compete with bigger names.
