Factors that Affect Solar Panel Costs in Radnor
The cost of installing a solar system in Radnor can vary by more than $10,000 from home to home. Your actual cost is dependent on several factors. The most significant one is your system size, and other factors include equipment choices, financing options and the solar installer you choose.
Solar Equipment
When it comes to estimating the price of a solar panel system in Radnor, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are mainly based on your home’s energy usage, which you can determine by looking at past electricity bills. Your total cost can increase by around $3,760 for each additional kilowatt you need.The solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you opt for the most efficient solar panel brands, you’ll end up paying more upfront than if you opted for the most affordable panels. However, higher efficiency could save you more over time on your power bills. In addition, extra products, such as solar batteries, can bring your total well above the Radnor average.
Solar Financing Terms
Many homeowners find the average cost of solar in Radnor to be too steep, even if the investment pays off over time. Fortunately, almost every solar installer in the area provides financing options. Solar loans substantially decrease upfront costs for most homeowners, but they also result in higher prices over time due to interest.It’s wise to include the interest you’ll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and the amount of time it’ll take to pay off the loan.
Solar Panel Installation Company
A final consideration when trying to evaluate the cost of solar for your home or business in Radnor is the company you get to install your PV system. As with choosing a company to install new cabinets, for example, there are plenty of solar installers that provide a range of services at different costs.Companies that only sell products with high efficiency and therefore a higher price point — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come at a higher cost. It’s best to do some research and find a company that has the products, warranties and services you want and also is within your budget.

How to Save on Solar Panels
The solar company you go with will influence not only your total costs, but also the types of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are a few important things you should keep in mind, including:
- Reputation: Your solar installer should have a good reputation as a company and have proven expertise in the field. A couple of ways to check this are to look for whether a company has technicians certified by the North American Board of Certified Energy Practitioners (NABCEP) and if it has good reviews from past customers.
- Installation Process: Homeowners should understand how exactly the installation process will be carried out, as well as important factors like the completion timeline.
- Solar Panel Brands: Different companies have various brands and types of panels. If you want a specific brand, make sure the solar panel company you’re considering has it.
- Contract: Before you sign a contract with a solar company, make sure to look it over fully so you understand the terms. Also, ask questions if you aren’t sure about some of the terms, such as what the warranty covers and what services you can expect from them.
EcoWatch's Radnor, IL Solar Cost FAQs
What is the average cost of installing solar panels in Radnor?
This is a tough question to answer precisely, because the cost depends on a few different factors. Broadly speaking, it costs about $18,800 for a 5-kW system and $37,600 for a 10-kW system after the ITC is applied. It will be more expensive if you want other solar equipment or higher quality panels, or if you have above-average energy usage. Conversely, you can spend less if you want a smaller solar panel system or cheaper solar panels.
Is cost the most important thing to keep in mind when buying solar panels?
Cost is a key factor to consider, but whether it’s the most important for you depends on your goals for going solar. In places where rooftop space is limited, efficiency can be more important than the cost. Other factors that are important to be mindful of are the quality and durability of your solar panels.
Can you sell solar power back to the grid in Radnor?
Each state has some kind of net metering programs except Tennessee, South Dakota and Alabama currently. Some states allow you to sell power back to the grid, but others just offer you credit toward your future electricity bills.
How often do you have to replace solar panels?
Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable at that time. What this means is their energy production will have decreased significantly after that point. You can decide to replace them after having them for that long or you can keep using them at a lower efficiency.
