Factors that Affect Solar Panel Costs in West Greenwich

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

Solar Equipment

The size of the solar system you need to offset your energy usage, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by about $4,070. The brand and type of equipment you choose for your solar system can increase or decrease 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 a small roof or just want maximum energy production, you can expect a higher equipment cost, but this can typically lead to more savings over time. Plus, if you want add-ons like an electric vehicle charger or solar batteries, this will also raise the cost.

Solar Financing Terms

If paying for a solar system out of pocket is out of reach, solar loans are a solid route because they reduce your upfront costs and let you pay for your system over five to seven years on average.However, the interest on solar loans also adds to your total costs, so it’s important to include that in your estimate as well. You can always reduce the total you pay in interest and in some cases even your APR by putting more money down.

Solar Panel Installation Company

The solar panel installer you select will impact your total cost to make the switch to solar power. Different companies will bill different amounts for the equipment and labor.Larger national companies usually have lower costs, but some local companies compete with them by offering sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or add-on services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels

The solar company you opt for 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 take into account, such as:

  • Contract: Before you sign a contract with a solar installer, make sure you read it through carefully so you understand the terms. Also, ask questions if you’re not sure about some of the terms, such as what to do if a component breaks or malfunctions and if there are any guarantees about energy production.
  • Reputation: Make sure your solar system installer has a good reputation by confirming it has certifications and licenses, checking its work history and reading reviews by previous customers and solar experts like the EcoWatch team.
  • Installation Process: When making the switch to solar power, it’s essential to keep an open line of communication with your solar panel installer. Make sure you understand how the installation process works and the completion timeline.
  • Solar Panel Brands: Different companies carry various brands and types of panels. If you know you want a specific brand, make sure the solar panel company you’re considering has it.

EcoWatch's West Greenwich, RI Solar Cost FAQs

How much does it cost to install solar panels in West Greenwich?

The average cost of solar panels in West Greenwich is about $20,350 for a 5-kW system and $40,700 for a 10-kW system before the ITC, but the actual cost will depend on stuff such as the model of solar panels you want, what size system you need and how much energy you consume.

Is it better to lease or buy solar panels in West Greenwich?

Leasing solar panels can be an option if you can’t afford to 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 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.

Can you sell solar power back to the grid in West Greenwich?

The majority of states offer 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 utility bills. Currently there are just three states that don’t have any net metering laws: Alabama, Tennessee and South Dakota.

How long do solar panels last in West Greenwich?

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 how much energy they produce will have decreased significantly after that point. You can decide to replace them after having them for that long or you can continue to use them at a lower efficiency.
