Factors that Affect Solar Panel Costs in Alton

The cost of installing a solar system in Alton can vary by more than $10,000 from home to home. Your actual cost depends on several factors. The biggest one is the size of the system you need, and other factors include equipment choices, financing options and the solar installer you choose.

Solar Equipment

The size of the solar energy system you need, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by nearly $2,910. The brand and type of equipment you want for your solar system can raise or lower the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these often come at a higher price than other brands. Efficiency also matters. Whether you're opting for high efficiency because you have limited roof space or just want maximum energy production, you can expect a higher equipment cost, but this can typically lead to greater savings over time. Also, if you want add-ons like an electric vehicle charger or solar batteries, this will also increase the cost.

Solar Financing Terms

Solar panels can save you money on utility bills over time, but they can also be a big investment. That's why many Alton homeowners choose to finance their solar panel systems to make going solar more affordable. Although solar loans make switching to solar energy more accessible for Alton homeowners, they can also raise the total you pay for your system, depending on your interest rate and how long you take to pay off the loan. If you put down a larger down payment, though, you can cut back on how much interest you have to pay.

Solar Panel Installation Company

The solar panel installer you pick will influence your total cost to go solar. Different companies will charge different amounts for the equipment and labor. Additionally, some companies in Alton are more knowledgeable about local solar incentives and can help you make good use of additional rebates or tax exemptions. Though, they may charge more for walking you through the whole process. Even if they cost more upfront, they could end up saving you more money in the long run.

How to Save on Solar Panels

The company that does your system installation will affect the warranties and brands available to you, and it will also have an impact on your total cost. Since selecting a company can be difficult, we have some tips to help you, such as:

  • Solar Panel Brands: Different companies will have different brands and models of panels. If you prefer a specific brand, make sure the solar panel installer you're considering has it.
  • Warranty: Warranties that provide coverage for replacement parts and repairs over around 25 years are the best you can get in the business, and offering such a warranty is one mark of a good company.
  • Contract: It's important to look over your solar installer's contract carefully to understand what services they will provide, what the warranty covers and what you can expect about the installation process.
  • Reputation: Long-standing companies likely have a high reputation. This is important because it ensures that it will not only see your solar installation through, but will also provide adequate aftercare and customer support, such as part repairs and replacements.

EcoWatch's Alton, NH Solar Cost FAQs

How much does it cost to install solar panels in Alton?

The average cost of solar panels in Alton is about $14,550 for a 5-kW system and $29,100 for a 10-kW system before the ITC, but the real cost will depend on certain factors like the kind of solar panels you want, what size system you need and how much energy you consume.

Should I lease or buy solar panels in Alton?

Leasing solar panels can be an option if you can't pay upfront or secure a solar loan, but since you don't own the system, you don't have access to many solar incentives. Also your home 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.

Is switching to solar power worth it?

Solar panels can be a great investment for a majority of homeowners, but they might not be worth it for everyone. If your home doesn't get enough sunlight and/or your power bills are already reasonably low, solar panels might not be for you.

How often do you have to replace solar panels?

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