Factors that Affect Solar Panel Costs in Lake Wisconsin
For many Lake Wisconsin homeowners, the decision to install solar panels rests on cost. However, the range of solar installation costs can be quite wide in Lake Wisconsin, with typical prices between $20,000 to $40,000. There are several factors that greatly influence the price you’ll pay, which we'll go over below.
Solar Equipment
The cost of solar panels varies by thousands of dollars due to some different factors. One of the notable factors is the system size, which is measured in kilowatts (kW). Solar power systems with better efficiency or power production need 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 $3,880.There are a lot of different solar panel brands and the one you pick also affects the cost. In many cases, the brands that are more efficient tend to also cost more. Plus, the type of equipment you choose can affect your total cost. If you just need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.
Solar Financing Terms
Solar panels can save you money on energy bills over time, but they can also be a big investment. That’s why many Lake Wisconsin homeowners opt to finance their solar panel systems to offset upfront costs.However, the interest on solar loans also increases your total costs, so it’s important to consider that as well. You can always reduce the total you pay in interest and in some cases even your APR by making a larger down payment.
Solar Panel Installation Company
A final factor to keep in mind when trying to estimate the cost of solar for your home or business in Lake Wisconsin is the company you choose to install your PV system. Similar to choosing a company to install new cabinets, for instance, you’ll have no shortage of solar installers that provide a range of services for different budgets.Larger national companies typically have lower costs, but some local companies keep up with them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or add-on services like electric car charger installation, they might be cheaper overall.
