Factors that Affect Solar Panel Costs in Wentzville

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

Solar Equipment

The cost of solar panels varies by thousands of dollars due to some different factors. One of the most significant factors is the system size, which is measured in kilowatts (kW). Solar power systems with better efficiency or power generation need better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $3,370.The brand and type of equipment you get for your solar system can increase or decrease 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 a small roof 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 additional equipment like an electric vehicle charger or solar batteries, this will also increase the cost.

Solar Financing Terms

If paying for solar panels in cash is out of reach, solar loans are a solid choice because they lower your upfront costs and allow you to pay for your system over five to seven years on average.It’s a good idea to add the interest you’ll pay in your final cost estimate. If you can afford to pay a larger down payment, you can reduce your total costs and how long it’ll take to pay off the loan.

Solar Panel Installation Company

Lastly, the company you opt for to install your solar panel system can impact your pricing. Wentzville’s solar companies all have different labor costs and add varying upcharges to equipment. Larger national companies usually have lower costs, but some local companies undercut them by offering sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or extra services like electric vehicle charger installation, they might be cheaper overall.

EcoWatch's Wentzville, MO Solar Cost FAQs

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

This is a tough question to answer precisely, because the cost depends on a few different factors. Broadly speaking, it costs about $16,850 for a 5-kW system and $33,700 for a 10-kW system after the ITC is applied. You can expect to pay more if you want extra solar equipment or more efficient panels, or if you have higher-than-average energy usage. Conversely, you can spend less if you go with a smaller solar panel system or less expensive solar panels.

Is cost the most important consideration when buying solar panels?

Cost is certainly one of the most important things to bear in mind when buying solar panels, but other important factors include efficiency, durability, and quality.

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

Each state has some form 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 energy bills.

How many solar panels should I get to power my home?

The exact number of solar panels you need depends on your household energy needs and the amount of 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 install between 20 and 35 panels to account for their typical energy usage.
