Factors that Affect Solar Panel Costs in Harrisburg

For many Harrisburg homeowners, the decision to go solar rests on cost. However, the range of solar installation costs can be quite wide in Harrisburg, with typical prices between $20,000 to $40,000. There are numerous factors that greatly influence the price you’ll pay, which we'll go over below.

Solar Equipment

Solar system size, which is measured in kilowatts, is one of the largest factors that determines the overall cost of going solar. For that reason, it’s a priority to accurately ascertain the size of the solar energy system needed for your home by figuring out your average energy use.The type of solar panels and equipment you want is another factor that will significantly impact costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to be more pricey. Plus, solar equipment goes beyond just the solar panels themselves. You’ll also need to think about the kind of racks used to mount the panels, inverters, solar batteries, etc. It’s important to take all of this into consideration when looking for a solar system that falls within your budget.

Solar Financing Terms

Solar panels can save you money on power bills over many years, but they can also be a big investment. That’s why many Harrisburg homeowners decide to finance their solar panel systems to make paying for solar more affordable.However, the interest on solar loans also increases your overall costs, so it’s important to consider that as well. You can always bring down the total you pay in interest and in some cases even your APR by putting more money down.

Solar Panel Installation Company

Finally, the company you choose to install your solar panel system can play a role in determining how much it costs. Harrisburg’s solar companies all have different labor costs and add varying upcharges to equipment. Larger national companies typically have lower costs, but some local companies compete with them by promoting sales and discounts. While the smaller companies might not have access to 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

The solar panel company you go with will be a major factor in determining not only your overall costs, but also the types of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are several important things you should keep in mind, including:

  • Installation Process: Homeowners should understand how exactly the installation process will be carried out, as well as important factors like the project timeline.
  • Contract: It’s important to look over your solar installer’s contract fully to understand what services they will provide, what the warranty covers and what expectations you should have about your solar system’s energy production.

The average cost of solar panels in Harrisburg is about $18,800 for a 5-kW system and $37,600 for a 10-kW system before the ITC, but the actual cost will depend on stuff such as the kind of solar panels you want, what size system you need and how much energy you consume.

What other factors should I consider in addition to cost when buying solar panels?

The upfront cost is a crucial factor to consider, but whether it’s the most important for you depends on your reasons for going solar. In places where rooftop space is limited, efficiency can be more important than the cost. Other factors that are important to consider are the quality and durability of your solar panels.

Can you sell solar power back to the grid in Harrisburg?

Most states offer net metering programs of some kind. Through these, you can either get paid for the extra power your system produces or or receive credits to put toward future energy bills. Currently there are just three states that don’t have any net metering laws: Alabama, Tennessee and South Dakota.

How many solar panels should I get to power my home?

The exact number of solar panels you need depends on your household energy needs and the average daily sunlight your roof gets. You can look at your energy bills for the past year to get an idea of the solar system size you'll need. The average household has to buy between 20 and 35 panels to cover their typical energy usage.
