Factors that Affect Solar Panel Costs in Johnston
While the average cost of a solar system 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.
