Factors that Affect Solar Panel Costs in Wentzville

Cost is often one of the most important factors for homeowners who are considering investing in solar. There are a few major factors that affect your total cost in Wentzville: solar equipment and system size, financing options and the solar installation company you choose. We’ll go over each of these briefly below.

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 higher efficiency or power generation require better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $3,370.The brand and kind of equipment you want for your solar system can increase or decrease the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these are often more expensive 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 more savings over time. Plus, if you want extra equipment like an electric vehicle charger or solar batteries, this will also raise the cost.

Solar Financing Terms

If paying for solar panels out of pocket is difficult, solar loans are an affordable choice because they cut back your upfront costs and let you pay for your system over five to seven years on average.It’s a good idea 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 significant cost factor you should consider is the installer you choose. Given the booming popularity of sustainable energy solutions in Wentzville, you’ll have plenty of options to choose from, but each comes at different price points for labor and equipment.You may notice national solar installers that have lower prices due to their larger brand name and access to bulk prices, or you might see small, local installation companies offering deals or promotions to compete with those larger companies.

How to Save on Solar Panels

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

  • Contract: When looking over your solar installer’s contract, ask for clarification about any terms you’re not sure of and be sure you understand what happens in scenarios like a system part breaking or if the company goes out of business.
  • Solar Panel Brands: The brand of solar panel you want to install plays a role in which company you should opt for, since different companies have different panels.
  • Warranty: A high-quality company rises above other companies by providing the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
  • Reputation: Companies that have been in business for many years likely have a good reputation. This is important because it ensures that it will not only see your solar project through, but will also provide quality aftercare and customer support, such as part repairs and replacements.

EcoWatch's Wentzville, MO Solar Cost FAQs

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

This is a difficult question to answer precisely, because the cost depends on a variety of 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 additional solar equipment or higher quality panels, or if you have above-average energy needs. On the other hand, you can spend less if you go with a smaller solar panel system or cheaper solar panels.

What other factors should I consider other than cost when buying solar panels?

Cost is without a doubt one of the most important things to keep in mind when buying solar panels, but other important factors include efficiency, durability, and quality.

Does Wentzville have a net metering program?

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

How many solar panels do I need to power my home?

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