Factors that Affect Solar Panel Costs in Portsmouth

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

Solar Equipment

When it comes to estimating the cost of a solar panel system in Portsmouth, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are primarily based on your home’s energy consumption, which you can gauge by looking at past power bills. Your overall cost can increase by around $4,070 for each additional kilowatt you need.Some solar brands — like Maxeon from SunPower — are more costly upfront but also tend to offer better efficiency. In a city like Portsmouth, where sunlight is relatively abundant, efficiency can quickly pay off. In addition, if you have a small roof or you don’t have a lot of space for your panels, higher efficiency options will be more impactful. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

Many homeowners find the average cost of solar in Portsmouth to be prohibitively expensive, even if the investment pays off over time. Thankfully, almost every solar company in the area offers financing options. Solar loans substantially decrease upfront costs in most cases, but they also result in paying more over time because of interest.It’s wise to add the interest you’ll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and how long it’ll take to pay back the loan.

Solar Panel Installation Company

A final consideration when trying to evaluate the cost of solar for your home or business in Portsmouth is the company you hire to install your solar system. As with choosing a company to build a deck or pool, for instance, there’s no shortage of solar installers that offer a range of services for different budgets.Additionally, some companies in Portsmouth know more about local solar incentives and can help you learn about additional rebates or tax exemptions. Though, they may charge more for that service. 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 choose will affect 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 several important things you should consider, such as:

  • Warranty: Each company may offer different kinds of warranties that cover different things. A 25-year, all-inclusive warranty is the gold standard.
  • Installation Process: Homeowners should make sure they know how exactly the installation process will be carried out, as well as important factors like the completion timeline.
  • Contract: When looking through your solar installer’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 if the company goes out of business.
  • Solar Panel Brands: Each solar panel brand and model has varying levels of quality, durability and energy efficiency. They will come at different costs as well. The company you choose plays a role in which solar panel brands you have access to.
