Factors that Affect Solar Panel Costs in Guilford
For many Guilford homeowners, the decision to adopt solar energy comes down to cost. However, the range of solar installation costs can be quite wide in Guilford, with typical prices between $20,000 to $40,000. There are various factors that greatly influence the price you’ll pay, which we'll go over below.
Solar Equipment
One of the most important factors to consider when it comes to the cost of adopting solar energy is the size of the solar system, which is measured in kilowatts (kW). The more power your household consumes, the larger your system will likely need to be. You can expect to spend about $3,750 per kilowatt in Guilford.The kind of solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you choose 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 energy bills. In addition, extra products, like solar batteries, can bring your total well above the Guilford average.
Solar Financing Terms
If paying for a solar system out of pocket is too expensive, solar loans are a popular route because they cut back your upfront costs and allow you to pay for your system over a term of, on average, between five and seven years.When trying to figure out your overall cost, you should also calculate the interest you’ll pay if you go with a solar loan. Also, paying more on your down payment can lower the total interest paid over time.
Solar Panel Installation Company
The solar company you select will affect your total cost to adopt solar power. Different companies will charge different amounts for the equipment and labor.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 additional services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels
Since the kind of solar panels and the company you choose significantly impacts your costs and your system’s efficiency, production, and durability, it’s important to pick the right ones for you. Here are some tips to keep in mind to help with your decision:
- Warranty: Each company may offer different types of warranties that cover different things. A 25-year, all-inclusive warranty is the gold standard.
- Contract: Look through the contract terms carefully to make sure you understand the cost breakdown, completion timeline incentives and warranties.
- 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 most likely has a good reputation and is qualified to get the job done well. Another way you can research your installer’s reputation is by reading reviews.
- Solar Panel Brands: Homeowners will have different preferences for panels based on their roof configurations and energy needs. Even though there are many options for which brand of solar panel you can get, not every company will have access to the exact one you may want or need, so make sure you peruse their list of options before deciding.
EcoWatch's Guilford, CT Solar Cost FAQs
How much does it cost to install solar panels in Guilford?
This is a hard question to answer precisely, because the cost depends on a few different factors. Generally speaking, it costs about $18,750 for a 5-kW system and $37,500 for a 10-kW system after the ITC is applied. It will be more expensive if you want extra solar equipment or more efficient panels, or if you have higher-than-average energy usage. On the flip side, you can spend less if you opt for a smaller solar panel system or cheaper solar panels.
Should I lease or buy solar panels in Guilford?
Leasing solar panels can be an option if you are unable to pay upfront or get a solar loan, but since you don’t own the system, you don’t have access to many solar incentives. Also your property value won’t increase, so you’ll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most bang for your buck from going solar.
How will having solar panels impact my home value?
Installing solar panels on your home can increase the value of your property by about 4%, according to research done by Zillow. The average home value in Guilford is currently $542,547, so you can look forward to a value of about $22,244 more than houses without a solar system. The exact figures will vary, but most experts agree that installing solar panels in Guilford is a worthwhile investment.
How many solar panels should I get to power my home?
To figure out how many solar panels you need, you should find out how much energy your home uses 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 house will need 20 to 35 panels.
