Solar Financing Terms

Solar panels can save you money on power bills over time, but they can also be a big investment. That’s why many South Londonderry homeowners opt to finance their solar panel systems to make going solar more affordable.It’s wise to include the interest you’ll pay in your final cost estimate. If you can afford to pay a higher down payment, you can reduce your total costs and how long it’ll take to pay back the loan.

Solar Panel Installation Company

The solar company you pick will affect your total cost to adopt solar power. Different companies will bill different amounts for the equipment and labor.You may see national solar installers that have lower prices because of their larger brand name and access to bulk prices, or you might see small, local installation companies offering deals or specials to compete with those larger companies.

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 pick the right ones for you. Here are some things to keep in mind to help with your decision:

  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for clean energy professionals. If your solar panel installer is NABCEP-certified, it likely has a good reputation and is qualified to do the job well. Another way you can verify your installer’s reputation is by reading reviews.
  • Contract: Before you sign a contract with a solar installer, be sure to look it over completely so you understand the terms. Also, ask questions if you’re not certain about some of the terms, such as what to do if a component breaks or malfunctions and what services you can expect from them.
  • Installation Process: Make sure you’re aligned with the company in regard to how the installation process will go and what needs to be done before your solar panels are installed, such as repairing your electrical system or roof.
  • Solar Panel Brands: Each solar panel brand and type offers varying levels of quality, longevity and energy efficiency. They will come at different costs as well. The company you choose plays a role in which solar panel brands you have access to.

EcoWatch's South Londonderry, PA Solar Cost FAQs

How much does it cost to install solar panels in South Londonderry?

This is a hard question to answer exactly, because the cost depends on a variety of factors. Broadly speaking, it costs about $17,750 for a 5-kW system and $35,500 for a 10-kW system after the ITC is applied. It will cost more if you want additional solar equipment or higher quality panels, or if you have above-average energy usage. On the other hand, you can spend less if you want a smaller solar panel system or less expensive solar panels.

Is it better to lease or buy solar panels in South Londonderry?

Leasing solar panels can be an appealing choice, as it commonly comes with low or $0 upfront payments. The drawback is that you won’t be able to save as much. If you lease, you don’t own the system, so you can’t claim any tax rebates and credits and your home value won’t increase. Buying solar panels is a better option if you want to get the most savings.

Can solar panels significantly reduce my energy bills?

It is possible to eradicate your electricity bills with solar panels, but for most homeowners throughout South Londonderry, that will require at least a 10-kW system. Not all homes can accommodate that size system, so you’ll want to contact a local solar installer to see how many panels can fit on your roof.

How long do solar panels last in South Londonderry?

On average, the lifespan of solar panels is about 25 to 30 years. Some even last up to 50 years, but their efficiency goes down by about 0.8% each year. You can choose to replace them sooner if you want to maintain a larger amount of energy production.
