Factors that Affect Solar Panel Costs in Greendale
There are a number of factors that can influence your total installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that does the installation.
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 greater 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 $3,880.The brand and type of equipment you get for your solar system can increase or decrease the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these often come at a higher price 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 can expect a higher equipment cost, but this can typically lead to greater savings over time. Plus, if you want extra equipment like an electric vehicle charger or solar batteries, this will also increase the cost.
Solar Financing Terms
For some homeowners, paying for solar panels out of pocket can be a challenge. Solar loans are available from most installers in Greendale, which can reduce, or in some cases completely eliminate, your upfront costs to make solar more affordable.It’s wise to factor 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 the amount of time it’ll take to pay off the loan.
Solar Panel Installation Company
The solar installation company you choose will impact your total cost to adopt solar energy. Different companies will bill different amounts for the equipment and labor.Additionally, some companies in Greendale know more about local solar incentives and can help you take advantage of additional rebates or tax exemptions. Though, they may charge more for walking you through the whole process. Even if they cost more upfront, they could end up saving you more money in the long run.

How to Save on Solar Panels
The solar panel company you opt for will affect not only your total costs, but also the kinds of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are some important things you should keep in mind, such as:
- Installation Process: Homeowners should understand how exactly the installation process will be carried out, as well as important factors like the project completion timeline.
- Warranty: An all-inclusive, 25-year warranty can help keep your solar panel system running for a long time and save you money on part replacement and repairs.
- Reputation: Solar system installers that have great reviews from their customers and that have been operating for many years in most cases offer high-quality solar panel installation and expertise.
- Solar Panel Brands: Not all solar installers offer the same brands of solar panels, so the brand and type of panel you want can play a considerable role in the company you go with.
