Factors that Affect Solar Panel Costs in Swansea

Cost is usually one of the most important factors for homeowners wanting to invest in solar. There are a few primary factors that will push your cost above or below the average in Swansea: solar equipment and system size, financing options and the solar installation company you choose. We’ll discuss each of these briefly below.

Solar Equipment

Solar 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 important to accurately assess the size of the solar energy system needed for your home by figuring out your energy needs.The brand and kind of equipment you get 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 limited roof space or just want maximum energy production, you can expect a higher equipment cost, but this can typically lead to greater savings over time. Also, if you want extra equipment like an electric vehicle charger or solar batteries, this will also raise the cost.

Solar Financing Terms

Most solar companies in Swansea have solar loans, which reduce your upfront costs of installing solar.When considering your overall cost, you should also calculate the interest you’ll pay if you opt for a solar loan. Also, paying more on your down payment can reduce the total interest paid over time.

Solar Panel Installation Company

The solar company you hire to handle your switch to green energy can have an effect on your total costs. There are about 3 solar installation companies operating in Swansea, and each can charge different amounts for labor and equipment.Additionally, some companies in Swansea have more knowledge about local solar incentives and can help you take advantage of additional rebates or tax exemptions. However, they may charge more for walking you through the whole process. Even if they cost more upfront, they could end up saving you more money in the long run.

How to Save on Solar Panels

The solar installer you opt for will influence not only your overall costs, but also the kinds of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are a few important things you should consider, such as:

  • Reputation: Companies that have been operating for many years likely have a good reputation. This is important because it ensures that it will not only see your solar installation through, but will also provide quality aftercare and customer service, such as part repairs and replacements.
  • Warranty: If you care about the longevity of your solar panel system, verifying that your company offers a 25-year, all-inclusive warranty can help put you at ease.
  • Solar Panel Brands: Each solar panel brand and model has varying levels of quality, longevity and energy efficiency. They will come at different costs as well. The company you choose impacts which solar panel brands you have access to.
  • Contract: It’s important to read your solar installer’s contract closely to understand what services they will provide, what the warranty covers and what expectations you should have about your solar system’s energy production.

EcoWatch's Swansea, MA Solar Cost FAQs

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

This is a hard question to answer precisely, because the cost depends on a variety of factors. Broadly speaking, it costs about $20,300 for a 5-kW system and $40,600 for a 10-kW system after the ITC is applied. It will cost more if you want additional solar equipment or higher quality panels, or if you have higher-than-average energy consumption. On the other hand, you can spend less if you opt for a smaller solar panel system or less efficient solar panels.

Is cost the most important thing to think about when buying solar panels?

Cost is a crucial factor to consider, but whether it’s the most important for you depends on your goals for going solar. In places where rooftop space is limited, efficiency can trump the cost. Other factors that are important to consider are the quality and durability of your solar panels.

Can solar panels completely eradicate my power bills?

It is possible to eradicate your electricity bills with solar panels, but for most homeowners in Swansea, that will require at least a 10-kW system. Not all homes can accommodate that size system, so you’ll want to contact a local solar installer to see how many panels can fit on your roof.

How often do you have to replace solar panels?

On average, solar panels can last about 25 to 30 years. Some even last up to 50 years, but their efficiency decreases by about 0.8% each year. You can choose to replace them sooner if you want to maintain a larger level of energy production.
