Factors that Affect Solar Panel Costs in Johnston

Cost is typically 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 Johnston: solar equipment and system size, financing options and the solar installation company you choose. We'll cover each of these briefly below.

Solar Equipment Size

When it comes to estimating the cost of solar panels in Johnston, one of the most important 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 determine by looking at past energy bills. Your total cost can increase by about $2,840 for each additional kilowatt you need. The brand and kind of equipment you want for your solar system can raise or lower the price quite significantly. If you prefer a brand name like Tesla or SunPower, these often have a higher price tag 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 will be looking at 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 increase the cost.

Solar Financing Terms

If paying for a solar system out of pocket is too expensive, solar loans are an affordable option because they decrease your upfront costs and let you pay for your system over five to seven years on average. It's wise to include 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 the amount of time it'll take to pay off the loan.

Solar Panel Installation Company

The last major cost factor you should keep in mind is the installer you choose. Given the booming popularity of green energy solutions in Johnston, you'll have plenty of options to choose from, but each comes at varying price points for labor and equipment. Larger national companies usually have lower costs, but some local companies keep up with them by offering sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or add-on services like electric vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels

There are many solar installers to choose from, all of which offer different warranties, solar panel brands and price points. To help you select the right company for you, here are some tips to keep in mind:

  • Reputation: Your solar installer should have a sound reputation as a company and have verifiable expertise in the field. A couple of ways to check this are to look for whether a company has technicians certified by the North American Board of Certified Energy Practitioners (NABCEP) and if it has good reviews from past customers.
  • Solar Panel Brands: The model of solar panel you want plays a role in which company you should opt for, since different companies have different panels.
  • Contract: Review the contract terms carefully to make sure you understand the cost breakdown, project completion timeline rebates and warranties.
  • Installation Process: Get details from your solar installer about the installation process and what to expect, including when the site survey will be completed and what the project timeline is.

EcoWatch's Johnston, RI Solar Cost FAQs

How much does it cost to install solar panels in Johnston?

This is a difficult question to answer exactly, because the cost depends on a variety of factors. Generally speaking, it costs about $14,200 for a 5-kW system and $28,400 for a 10-kW system after the ITC is applied. It will cost more if you want other solar equipment or higher quality panels, or if you have above-average energy usage. Conversely, you can spend less if you opt for a smaller solar panel system or less efficient solar panels.

Can you get solar panels for free in Johnston?

You can't get solar panels for free in Johnston. However, you may still be able to afford them on a lower budget. You can lease solar panels for a low upfront cost or, if you'd prefer to own your solar panels, you can finance them with a solar loan.

Is switching to solar power worth it?

Solar panels can be a great investment for lots of homeowners, but they might not be worth it for everyone. If your home doesn't get enough sunlight and/or your power bills are already reasonably low, solar panels might not be for you.

How long do solar panels last in Johnston?

Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely at that time. What this means is the amount of energy they produce will have decreased significantly after that point. You can opt to replace them after having them for that long or you can continue to use them at a lower efficiency.
