Factors that Affect Solar Panel Costs in Janesville

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

Solar Equipment

When it comes to estimating the price of a solar panel system in Janesville, one of the most important 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 usage, which you can determine by looking at past energy bills. Your total cost can increase by around $2,600 for each additional kilowatt you need. There are several different solar panel brands and the one you choose also affects the cost. In many cases, the brands that have better efficiency tend to also be more expensive. Additionally, the type of equipment you're looking to install can affect your total cost. If you only need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

If paying for solar panels out of pocket is out of reach, solar loans are an affordable choice because they reduce your upfront costs and let you pay for your system over five to seven years on average. When considering your overall cost, you should also calculate the interest you'll pay if you choose to go with a solar loan. Also, paying more on your down payment can reduce the total interest paid over time.

Solar Panel Installation Company

A final consideration when trying to evaluate the cost of solar for your home or business in Janesville is the company you get to install your solar panel system. Similar to choosing a company to build a deck or pool, for instance, you'll have no shortage of solar installers that provide a range of services for different budgets. You may come across national solar installers that have lower prices because of their larger brand name and access to bulk equipment prices, or you might see small, local installation companies offering deals or specials to compete with those major players.

How to Save on Solar Panels

There are a large number of companies to choose from in Janesville, and some homeowners feel overwhelmed considering their options. Selecting the right company for you can be tough, so here are some tips to help you decide:

  • Warranty: Warranties that provide coverage for replacement parts and repairs over a long period of time such as 25 years are the best you can get in the business, and offering that kind of warranty is one sign of a quality company.
  • Contract: Though reading through a contract can be tedious, it's important to do it fully so you can be sure you understand how much the equipment and services will cost and how part repairs and replacements will be handled.
  • Solar Panel Brands: Each solar panel brand and type offers varying levels of quality, durability and energy efficiency. They will come at different price points as well. The company you choose plays a role in which solar panel brands you have access to.
  • Reputation: Make sure your solar company has a good reputation by confirming it has certifications and licenses, checking how long it's been in business and reading reviews by past customers and solar experts like EcoWatch.

EcoWatch's Janesville, WI Solar Cost FAQs

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

The average cost of solar panels in Janesville is about $13,000 for a 5-kW system and $26,000 for a 10-kW system before the ITC, but the actual cost will depend on things like the kind of solar panels you want, what size system you need and how much energy you use.

Should I lease or buy solar panels in Janesville?

Leasing solar panels can be an option if you are unable to pay upfront or get a solar loan, but since you don't own the system, you can't take advantage of many solar incentives. Also your property value won't increase, so you'll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most bang for your buck from going solar.

How much can I save on energy bills after installing solar panels?

Solar panels can potentially eliminate your electricity bills depending on your location and how much sunlight your home gets. Even if it doesn't get rid of them completely, you can save a lot of money on your bills, about $1,011.47 per year.

What solar power system size is right for my home?

To figure out what solar panel system size 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 home will need 20 to 35 panels.
