Factors that Affect Solar Panel Costs in Preston

There are several criteria that can influence your total installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that performs the installation.

Solar Equipment

The size of the solar panel system you need, 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 $2,600. The kind of solar equipment you choose can increase or decrease your cost 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. However, more efficient panels could save you more in the long run on your power bills. In addition, extra products, like solar batteries, can bring your total well above the Preston average.

Solar Financing Terms

For some homeowners, paying for a solar system out of pocket can be financially overwhelming. Solar loans are provided by most installers in Preston, which can reduce, or in some cases eliminate, your upfront costs to make solar more accessible. However, the interest on solar loans also adds to your overall costs, so it's crucial to take that into consideration as well. You can always bring down the total you pay in interest and in some cases even your APR by putting more money down.

Solar Panel Installation Company

Finally, the company you choose to install your solar panel system can influence how much you pay. Preston's solar companies all have different labor costs and add varying upcharges to equipment. Additionally, some companies in Preston know more about local solar incentives and can help you make good use of 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 end up saving you more money in the long run.

How to Save on Solar Panels

The company that does your system installation will affect the warranties and brands you have access to, and it will also have an impact on your total cost. Since picking a company can be a challenge, we have some tips to help you, such as:

  • Installation Process: Homeowners should make sure they know how exactly the installation process will go, as well as important factors like the project timeline.
  • Solar Panel Brands: Different companies have different brands and models of panels. If you prefer a specific brand, make sure the solar panel installer you're considering has it.
  • Warranty: A comprehensive, 25-year warranty can help keep your solar system running for a long time and save you money on part replacement and repairs.
  • Contract: Even though reading through a contract can take a lot of time, it's important to do it fully so you can make sure you understand how much the equipment and services will cost and how part repairs and replacements will be handled.

EcoWatch's Preston, ID Solar Cost FAQs

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

This is a hard question to answer precisely, because the cost depends on a few different factors. Generally speaking, it costs about $13,000 for a 5-kW system and $26,000 for a 10-kW system after the ITC is applied. You can expect to pay more if you want other solar equipment or more efficient panels, or if you have above-average energy needs. On the other hand, you can spend less if you choose a smaller solar panel system or less efficient solar panels.

What other factors should I consider in addition to cost when buying solar panels?

The initial cost is a key factor to consider, but whether it's the most important for you depends on your goals for going solar. In areas where rooftop space is limited, efficiency can trump the cost. Other factors that are important to think about are the quality and durability of your solar panels.

Does Preston have a net metering program?

Each state has some kind of net metering programs except Tennessee, South Dakota and Alabama currently. Some states let you sell power back to the grid, but others just give you credit toward your future electricity bills.

What solar power system size is right for my home?

To figure out what solar panel system size you need, you need to know how much energy your home requires and how much sunlight your home gets. For a general estimate, however, since each panel can usually produce about 250 to 400 watt-hours per hour, the average house will need 20 to 35 panels.
