Factors that Affect Solar Panel Costs in South Londonderry

While the average cost of a solar system in South Londonderry is $11,870, your actual cost may be higher or lower than that. There are quite a few factors that can have a sizable impact on the cost of a residential solar panel installation. Below are some of the more crucial things to take into consideration.

Solar Equipment

One of the most important factors to consider when it comes to the cost of installing solar panels is the size of the solar system, which is measured in kilowatts (kW). The more electricity your household consumes, the larger your system will likely need to be. You can expect to spend around $2,550 per kilowatt in South Londonderry. Some solar panel brands — like Maxeon from SunPower — are more costly upfront but also tend to offer higher efficiency. In a city like South Londonderry, where sunlight is relatively abundant, efficiency can quickly pay off. Also, if you have a small roof or limited space for your panels, higher efficiency options will be a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

Many homeowners find the average cost of solar in South Londonderry to be too steep, even if the investment pays off over time. Fortunately, almost every solar company in the area offers financing options. Solar loans remarkably decrease upfront costs in most cases, but they also lead to higher prices over time because of interest. 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're only able to 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 securing a solar loan with a low interest rate could reduce your costs remarkably.

Solar Panel Installation Company

The solar company you choose will impact your total cost to adopt solar energy. Different companies will bill different amounts for the equipment and labor. You may see national solar installers that have lower prices due to their larger brand name and access to bulk equipment prices, or you might see small, local installation companies offering deals or promotions to compete with those major players.

How to Save on Solar Panels

There are numerous companies to choose from in South Londonderry, 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:

  • Warranty: If you're concerned about the durability of your solar system, checking if your company offers a 25-year, all-inclusive warranty can help put you at ease.
  • Contract: Look through the contract terms closely to make sure you understand how much it will cost, project timeline incentives and warranties.
  • Reputation: Solar system installers that have great reviews from their customers and that have been operating for many years likely offer high-quality solar panel installation and expertise.
  • Solar Panel Brands: Different companies offer different brands and models of panels. If you know you want a specific brand, make sure the solar installer you're considering has it.

EcoWatch's South Londonderry, PA Solar Cost FAQs

What is the average cost of installing solar panels in South Londonderry?

This is a difficult question to answer precisely, because the cost depends on a variety of factors. Broadly speaking, it costs about $12,750 for a 5-kW system and $25,500 for a 10-kW system after the ITC is applied. You can expect to pay more if you want extra solar equipment or more efficient panels, or if you have higher-than-average energy consumption. Conversely, you can spend less if you choose a smaller solar panel system or less expensive solar panels.

Are solar panels free in South Londonderry?

You can't get solar panels for free in South Londonderry. However, you may still be able to get them on a lower budget. You can lease solar panels for a low upfront cost or, if you'd prefer to own your solar panels, you can finance them with a solar loan.

Does South Londonderry have a net metering program?

The majority of states have net metering programs of some kind. Through these, you can receive compensation for the extra power your system generates or or receive credits to put toward future electricity bills. Currently there are just three states that don't have any net metering laws: Alabama, Tennessee and South Dakota.

How many solar panels do I need to power my home?

To figure out what solar panel system size you need, you need to know how much energy your home needs and how much sunlight your home gets. For a general estimate, however, since each panel can generally produce about 250 to 400 watt-hours per hour, the average household will need 20 to 35 panels.
