Factors that Affect Solar Panel Costs in Lewiston

There are a number of factors that can affect your total installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar panels.

Solar Equipment

The size of the solar energy system you need for your home, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, your total will most likely increase by around $3,800. The kind of solar panels and equipment you choose is another factor that will largely affect costs. Solar panels that are more efficient, like monocrystalline panels, tend to cost more. Further, solar equipment consists of more than just the solar panels themselves. You’ll also need to make decisions 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’s in your budget.

Solar Financing Terms

If paying for a solar system out of pocket is too expensive, solar loans are a popular option because they reduce your upfront costs and allow you to pay for your system over a term of, on average, between five and seven years.However, the interest on solar loans also adds to your total costs, so it’s vital to consider that as well. You can always bring down the total you pay in interest and possibly even your APR by putting more money down.

Solar Panel Installation Company

Lastly, the company you choose to install your solar panels can affect the cost. Lewiston’s solar companies all have different labor costs and add varying upcharges to equipment. Larger national companies generally have lower costs, but some local companies keep up with them by offering sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or extra services like electric car charger installation, they might be cheaper overall.

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 selecting a company can be a challenge, we have some tips to help you, such as:

  • Reputation: Solar installers that have great reviews from their customers and that have been operating for many years most likely offer high-quality solar panel installation and expertise.
  • Solar Panel Brands: Each solar panel brand and kind has varying levels of quality, longevity and energy efficiency. They will come at different price points as well. The company you choose affects which solar panel brands you have access to.
  • Warranty: If you’re concerned about the durability of your solar panels, ensuring your company offers a 25-year, all-inclusive warranty can help put you at ease.
  • Installation Process: One of the most important things to understand when going solar is the installation process itself. Be sure to align on any details you should know with your solar company, such as what permits you should acquire and what the project timeline is.

EcoWatch's Lewiston, ME Solar Cost FAQs

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

The average cost of solar panels in Lewiston is about $19,000 for a 5-kW system and $38,000 for a 10-kW system before the ITC, but the real cost will depend on things like the kind of solar panels you want, what size system you need and how much energy you use.

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

Leasing solar panels can be an option if you are unable to pay upfront or secure a solar loan, but since you don’t own the system, you can’t take advantage of 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 financial benefits from going solar.

How will having solar panels impact my home value?

Solar panels can increase your property’s value remarkably 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?

The exact number of solar panels you need depends on your household energy consumption and the average daily sunlight your roof gets. You can take a look at your energy bills for the past year to get an idea of the solar system size you'll need. The average household has to buy between 20 and 35 panels to cover their typical energy usage.
