Factors that Affect Solar Panel Costs in West Allis
Cost is usually one of the most important factors for homeowners who are considering investing in solar. There are a few major factors that will push your cost above or below the average in West Allis: solar equipment and system size, financing options and the solar installation company you choose. We’ll discuss each of these briefly below.
Solar Equipment
The size of the solar energy system you need, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by about $3,880. The brand and type of equipment you get for your solar system can raise or lower 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 can expect a higher equipment cost, but this can typically lead to greater savings over time. Plus, if you want add-ons like an electric vehicle charger or solar batteries, this will also raise the cost.
Solar Financing Terms
Many homeowners find the average cost of solar in West Allis to be too expensive, even if the investment pays off over time. Fortunately, nearly every solar installer in the area offers financing options. Solar loans greatly decrease upfront costs in most cases, but they also result in a higher cost over time due to interest.Though solar loans make going solar more accessible for West Allis homeowners, they can also add to the total you pay for your system, depending on your interest rate. If you put down a larger down payment, though, you can avoid paying as much in interest.
Solar Panel Installation Company
A final consideration when trying to evaluate the cost of solar for your home or business in West Allis is the company you hire to install your PV system. Similar to choosing a company to build a deck or pool, for instance, there’s no shortage of solar installers that offer a range of services at different price points.Companies that only sell products with high efficiency and therefore a higher price point — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come at a higher cost. It’s best to do some research and decide on the company that offers the products, warranties and services you’re looking for and also fit into your budget.

EcoWatch's West Allis, WI Solar Cost FAQs
How much does it cost to install solar panels in West Allis?
This is a tough question to answer precisely, because the cost depends on many factors. Generally speaking, it costs about $19,400 for a 5-kW system and $38,800 for a 10-kW system after the ITC is applied. It will cost more if you want extra solar equipment or more efficient panels, or if you have higher-than-average energy usage. On the flip side, you can spend less if you opt for a smaller solar panel system or less expensive solar panels.
Is cost the most important consideration when buying solar panels?
Cost is a key factor to consider, but whether it’s the most important for you depends on your goals for going solar. In cities where rooftop space is limited, efficiency can trump the cost. Other factors that are important to think about are the quality and durability of your solar panels.
Is making the switch to solar worth it?
Solar panels can be a good investment for a majority of homeowners, but they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight and/or your power bills are already pretty low, solar panels might not be for you.
How long do solar panels last in West Allis?
Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable at that time. What this means is their energy production will have decreased significantly after that point. You can opt to replace them once you've had them for that long or you can keep using them at a lower efficiency.
