Factors that Affect Solar Panel Costs in Winchester

Cost is usually one of the most important factors for homeowners wanting to invest in solar. There are a few primary factors that determine your overall cost in Winchester: solar equipment and system size, financing options and the solar installation company you choose. We'll go over each of these briefly below.

Solar Equipment

The cost of solar panel systems varies by thousands of dollars due to a few different factors. One of the major factors is the system size, which is measured in kilowatts (kW). Solar power systems with greater efficiency or power generation require better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $2,910. The model of solar panels and equipment you choose is another factor that will considerably impact costs. Solar panels that are more efficient, like monocrystalline panels, tend to come at a higher price. 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

Many homeowners find the average cost of solar in Winchester to be prohibitively costly, even if the investment pays off over time. Fortunately, almost every solar company in the area provides financing options. Solar loans remarkably decrease upfront costs for most homeowners, but they also result in a higher cost over time due to interest. When estimating your overall cost, you should also calculate the interest you'll pay if you choose to go with a solar loan. Also, paying more on your down payment can lower the total interest paid over time.

Solar Panel Installation Company

A final consideration when trying to estimate the cost of solar for your home or business in Winchester is the company you hire to install your solar panel system. As with choosing a company to renovate your kitchen, for example, there's no shortage of solar installers that provide a range of services for different budgets. Some companies only sell high-efficiency and high-priced products — 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 decide on the company that offers the products, warranties and services you're looking for and also is within your budget.

How to Save on Solar Panels

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

  • Installation Process: One of the most important things to understand when going solar is the installation process itself. Be sure to clarify any details you should know with your solar company, such as what permits you should acquire and what the project timeline is.
  • Warranty: If you're worried about the durability of your solar panels, checking if your company offers a 25-year, all-inclusive warranty can give you some peace of mind.
  • Contract: When reading over your solar installer's contract, ask questions about any terms you're not sure of and make sure you understand what happens in scenarios like a system part breaking or if the company goes out of business.
  • Solar Panel Brands: The model of solar panel you'd like to get plays a part in which company you should choose, since different companies offer different panels.

EcoWatch's Winchester, NH Solar Cost FAQs

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

This is a difficult question to answer exactly, because the cost depends on a few different factors. Generally speaking, it costs about $14,550 for a 5-kW system and $29,100 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 above-average energy consumption. Conversely, you can spend less if you want a smaller solar panel system or less efficient solar panels.

Is it better to lease or buy solar panels in Winchester?

Leasing solar panels can be an attractive choice, as it commonly comes with low or $0 upfront payments. The drawback is that you won't be able to save as much. If you lease, you don't own the system, so you can't claim any tax rebates and credits and your home value won't increase. Buying solar panels is a better option if you want to maximize your savings.

Does Winchester have a net metering program?

The majority of states have net metering programs of some kind. Through these, you can either 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 often do you have to replace solar panels?

Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they should be disposed of at that time. What this means is the amount of energy they produce will have decreased significantly after that point. You can replace them once you've had them for that long or you can continue to use them at a lower efficiency.
