Factors that Affect Solar Panel Costs in Sandown

Even though the average cost of a solar system in Sandown is $9,818, your final cost may differ. There are several factors that can have a sizable impact on the cost of a residential solar panel installation. Below are some of the more crucial things to consider.

Solar Equipment

The cost of solar panel systems varies by thousands of dollars due to some different factors. One of the notable factors is the system size, which is measured in kilowatts (kW). Solar power systems with greater efficiency or power production need 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. There are a lot of different solar panel brands and the one you pick also affects the cost. Generally speaking, the brands that are more efficient tend to also be more expensive. Additionally, the type of equipment you want to install can affect your total cost. If you just need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

Many homeowners find the average cost of solar in Sandown to be prohibitively steep, even if the investment pays off over time. Thankfully, nearly every solar company in the area offers financing options. Solar loans greatly decrease upfront costs for most homeowners, but they also lead to higher prices over time due to interest. However, the interest on solar loans also increases your overall costs, so it's vital to keep that in mind as well. You can always reduce the total you pay in interest and possibly even your APR by putting more money down.

Solar Panel Installation Company

The solar company you choose to handle your switch to renewable energy can play a role in your total costs. There are about 3 solar installation companies operating in Sandown, and each can charge varying amounts for labor and equipment. Larger national companies generally have lower costs, but some local companies undercut 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

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

  • Solar Panel Brands: The brand of solar panel you'd like to get plays a role in which company you should choose, since different companies offer different panels.
  • Contract: When looking over your solar company's contract, ask for clarification about any terms you're not sure of and be sure you understand what happens in scenarios such as a system part breaking or the company going out of business.
  • Installation Process: Homeowners should make sure they understand how exactly the installation process will go, as well as important factors like the project timeline.
  • Reputation: Long-running companies likely have a good reputation. This is important because it ensures that it will not only see your solar project through, but will also provide quality aftercare and customer service, such as part repairs and replacements.

EcoWatch's Sandown, NH Solar Cost FAQs

What is the average cost of installing solar panels in Sandown?

This is a difficult question to answer exactly, because the cost depends on a variety of 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. It will cost more if you want other solar equipment or more efficient panels, or if you have above-average energy consumption. On the other hand, you can spend less if you choose a smaller solar panel system or less efficient solar panels.

Is cost the most important consideration when buying solar panels?

Cost is without a doubt one of the most important things to bear in mind when buying solar panels, but other important factors include efficiency, durability, and quality.

How will solar panels impact my property value?

Solar panels can increase your property's value considerably as long as you buy or finance your panels and don't go for a solar lease or power purchase agreement (PPA). According to research done by Zillow, the average home value increases by about 4.1% after installing a solar system."

What solar power system size is right for my home?

To figure out what solar panel system size you need, you need to know how much energy your home requires and how much sunlight your home gets. For a general estimate, however, since each panel can usually produce about 250 to 400 watt-hours per hour, the average house will need 20 to 35 panels.
