Factors that Affect Solar Panel Costs in Londonderry

The cost of installing a solar system in Londonderry can vary by more than $10,000 from home to home. Your actual cost is determined by several factors. The most significant one is your system size, and other factors include equipment choices, financing options and the solar company you choose.

Solar Equipment Size

System size is one of the largest factors that affects the overall cost of installing solar panels. That's why it's crucial to accurately ascertain the size of the solar energy system needed for your home by figuring out your energy needs. The kind of solar panels and equipment you choose is another factor that will significantly affect costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to cost more. Plus, solar equipment consists of more than just the solar panels themselves. You'll also need to decide on the kind of racks used to mount the panels, inverters, solar batteries, etc. It's important to take all of this into consideration when researching a solar system that's in your budget.

Solar Financing Terms

If paying for a solar system in cash is out of reach, solar loans are a popular route because they decrease 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 loans, 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 getting a solar loan with a low APR could reduce your costs remarkably.

Solar Panel Installation Company

Lastly, the company you opt for to install your solar panels can affect the cost. Londonderry's solar companies all have different labor costs and add varying upcharges to equipment. Additionally, some companies in Londonderry know more about local solar incentives and can help you learn about additional rebates or tax exemptions. However, they may charge more for walking you through the whole process. Even if they cost more upfront, they could end up saving you more money in the long run.
