Factors that Affect Solar Panel Costs in Johnston

While the average cost of solar panels in Johnston is $18,556, your final cost may be higher or lower than that. There are several factors that can have a major impact on the cost of a residential solar panel installation. Below are some of the more important things to take into consideration.

Solar Equipment

When it comes to estimating the cost of a solar system in Johnston, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are mainly based on your home's energy consumption, which you can figure out by looking at past power bills. Your overall cost can increase by about $2,770 for each additional kilowatt you need. The type of solar panels and equipment you get is another factor that will largely impact costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to come at a higher price. Furthermore, solar equipment is more than just the solar panels themselves. You'll also need to make decisions about the kind of racks used to mount the panels, inverters, solar batteries, etc. It's important to take all of this into consideration when looking into a solar system that falls within your budget.

Solar Financing Terms

Most solar companies in Johnston offer solar loans, which reduce the initial cost of installing solar. When figuring out your overall cost, you should also calculate the interest you'll pay if you decide on a solar loan. Also, paying a higher down payment can lower the total interest paid over time.

Solar Panel Installation Company

Finally, the company you opt for to install your solar panels can play a part in determining your pricing. Johnston's solar companies all have different labor costs and add varying upcharges to equipment. Larger national companies generally have lower costs, but some local companies compete with them by offering sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or additional services like electric vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels

There are numerous companies available in Johnston, and some homeowners feel overwhelmed considering their options. Choosing the right company for you can be difficult, so here are some tips to help you decide:

  • Contract: Look through the contract terms thoroughly to make sure you understand how much it will cost, completion timeline rebates and warranties.
  • Warranty: Each company may offer different types of warranties that cover different things. A 25-year, all-inclusive warranty is the gold standard.
  • Solar Panel Brands: Different companies will carry various brands and models of panels. If you want a specific brand, make sure the solar panel installer you're considering has it.
  • Reputation: Long-running companies likely have a solid reputation. This is important because it ensures that it will not only see your solar installation through, but will also provide adequate aftercare and customer support, such as part repairs and replacements.

EcoWatch's Johnston, IA 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 many factors. Generally speaking, it costs about $13,850 for a 5-kW system and $27,700 for a 10-kW system after the ITC is applied. It will be more expensive if you want additional solar equipment or higher quality panels, or if you have above-average energy usage. On the flip side, you can spend less if you opt for a smaller solar panel system or less efficient solar panels.

Is it better to lease or buy solar panels in Johnston?

Leasing solar panels can be an attractive choice, as it commonly comes with low or $0 upfront payments. The drawback is that you won't be able to save as much. If you lease, you don't own the system, so you can't claim any tax rebates and credits and your home value won't increase. Buying solar panels is a better option if you want to maximize your savings.

Can you sell solar power back to the grid in Johnston?

The majority of states offer net metering programs of some kind. Through these, you can be compensated for the extra power your system generates or or receive credits to put toward future energy bills. Currently there are just three states that don't have any net metering laws: Alabama, Tennessee and South Dakota.

What solar power system size is right for my home?

The exact number of solar panels you need depends on your household energy usage and the average daily sunlight your roof gets. You can take a look at your energy bills for the past year to get an idea of the solar system size you'll need. The average household has to get between 20 and 35 panels to cover their typical energy usage.
