Factors that Affect Solar Panel Costs in Portsmouth

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

Solar Equipment Size

System size is one of the largest factors that determines the overall cost of going solar. That's why it's important to accurately assess the size of the solar energy system needed for your home by figuring out your typical energy use. There are many different solar panel brands and the one you choose also changes the cost. Generally speaking, the brands that have better efficiency tend to also cost more. Plus, the type of equipment you choose can affect your total cost. If you just need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

Most solar installers in Portsmouth have solar loans, which reduce your upfront costs of installing solar. However, the interest on solar loans also adds to your overall costs, so it's vital to consider that as well. You can always reduce the total you pay in interest and possibly even your APR by making a larger down payment.

Solar Panel Installation Company

The remaining key cost factor you should take into consideration is the installer you choose. Given the booming popularity of green energy solutions in Portsmouth, you'll have many options to choose from, but each comes at different price points for labor and equipment. The company's size can sometimes play the most considerable role in the installation costs. Larger national companies, like SunPro and Sunrun, often have lower pricing because of access to greater resources and bulk pricing. Smaller local companies might be more costly, but they generally have better customer service and more customization options, and the occasional sale or discount can bring their pricing down to compete with bigger names.

How to Save on Solar Panels

The solar panel company you choose will impact not only your overall costs, but also the kinds of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are some important things you should consider, including:

  • Solar Panel Brands: The brand of solar panel you need to get plays a role in which installer you should choose, since different companies have different panels.
  • Reputation: Companies that have been in business for many years likely have a solid reputation. This is important because it ensures that it will not only see your solar project through, but will also provide adequate aftercare and customer support, such as part repairs and replacements.
  • Installation Process: When going solar, it's essential to maintain an open line of communication with your solar panel installer. See to it that you understand how the installation process works and the project timeline.
  • Contract: Review the contract terms thoroughly to make sure you understand the cost breakdown, project timeline incentives and warranties.
