Factors that Affect Solar Panel Costs in Dennis

For many Dennis homeowners, the decision to install a solar energy system rests on cost. However, the range of solar installation costs can be quite wide in Dennis, with typical prices between $20,000 to $40,000. There are a few factors that considerably influence the price you’ll pay, which we'll go over below.

Solar Equipment

System size, which is measured in kilowatts, is one of the largest factors that influences the overall cost of installing solar panels. That’s why it’s crucial to accurately ascertain the size of the solar energy system needed for your home by figuring out your average energy use.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 opt for the most efficient solar panel brands, you’ll end up paying more upfront than if you opted for the most affordable panels. On the other hand, more efficient panels could save you more over time on your power bills. Additionally, extra products, like solar batteries, can bump up your total well above the Dennis average.

Solar Financing Terms

Many homeowners find the average cost of solar in Dennis to be too costly, even if the investment pays off over time. Fortunately, almost every solar company in the area offers financing options. Solar loans drastically decrease upfront costs in most cases, but they also result in paying more over time due to interest.Although solar loans make switching to solar energy more accessible for Dennis homeowners, they can also raise the total you pay for your system, depending on your interest rate. 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 installation company you pick will impact your total cost to adopt solar energy. Different companies will bill different amounts for the equipment and labor.Additionally, some companies in Dennis have more knowledge about local solar incentives and can help you learn about 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 help you save more money in the long run.

How to Save on Solar Panels

The company that does your solar panel installation will affect the warranties and brands you have access to, and it will also have an impact on your total cost. Because selecting 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 need to know with your solar company, such as what permits you should acquire and what the project timeline is.
  • Solar Panel Brands: Not all solar installers offer the same brands of solar panels, so the brand and type of panel you want can play a big role in the company you hire.
  • Contract: When reading through 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 the company going out of business.
  • Warranty: An all-inclusive, long-term warranty can help keep your solar panels running for a long time and save you money on repairs and maintenance.

EcoWatch's Dennis, MA Solar Cost FAQs

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

The average cost of solar panels in Dennis is about $20,300 for a 5-kW system and $40,600 for a 10-kW system before the ITC, but the actual cost will depend on things like the model of solar panels you want, what size system you need and how much energy you consume.

Should I lease or buy solar panels in Dennis?

Leasing solar panels can be an attractive choice, as it commonly comes with low or $0 upfront payments. The downside 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 incentives and your home value won’t increase. Buying solar panels is a better option if you want to maximize your savings.

Does Dennis have a net metering program?

Most states have net metering programs of some kind. Through these, you can get paid for the extra power your system generates or or receive credits to put toward future energy bills. Currently there are just three states that don’t have any net metering laws: Alabama, Tennessee and South Dakota.

What solar power system size is right for my home?

The exact number of solar panels you need depends on your household energy usage and how much 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 install between 20 and 35 panels to cover their typical energy usage.
