Factors that Affect Solar Panel Costs in Derry

There are several factors that can influence your total installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that does the installation.

Solar Equipment

The cost of solar panels varies by thousands of dollars due to some different factors. One of the main factors is the system size, which is measured in kilowatts (kW). Solar power systems with greater efficiency or power generation use 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 $4,220.The brand and kind of equipment you choose 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 come at a higher price 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 add-ons like an electric vehicle charger or solar batteries, this will also increase the cost.

Solar Financing Terms

If paying for a solar system out of pocket is too expensive, solar loans are an affordable option because they cut back your upfront costs and let you pay for your system over a term of, on average, between five and seven years.When figuring out 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

Finally, the company you get to install your solar panels can affect the cost. Derry’s solar companies all have different labor costs and add varying upcharges to equipment. Larger national companies generally have lower costs, but some local companies compete with them by offering sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or add-on services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels

There are a lot of companies available in Derry, and some homeowners feel overwhelmed considering their options. Choosing the right company for you can be difficult, so here are some tips to help you decide:

  • Installation Process: Get detailed information from your solar company about the installation process and what to expect, including when the site survey will be done and what the project timeline is.
  • Solar Panel Brands: Not all solar installers have the same brands of solar panels, so the brand and type of panel you want can play a considerable role in the company you hire.
  • Reputation: Make sure your solar company has a good reputation by verifying it has certifications and licenses, checking how long it's been in business and reading reviews by previous customers and solar experts like the EcoWatch team.
  • Warranty: Warranties that provide coverage for defective panels and repairs over a long period of time such as 25 years are the gold standard in the business, and offering that kind of warranty is one indication of a quality company.
