Factors that Affect Solar Panel Costs in Antioch
For many Antioch homeowners, the decision to adopt solar energy depends on cost. However, the range of solar installation costs can be quite wide in Antioch, with typical prices between $20,000 to $40,000. There are a few factors that considerably influence the price you’ll pay, which we'll go over below.
Solar Equipment
System size, which is measured in kilowatts, is one of the largest factors that determines the overall cost of installing solar panels. For that reason, it’s a priority to accurately assess the size of the solar energy system needed for your home by figuring out your typical energy use.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 often have a higher price tag 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 greater savings over time. Plus, if you want add-ons like an electric vehicle charger or solar batteries, this will also increase the cost.
Solar Financing Terms
Many homeowners find the average cost of solar in Antioch to be prohibitively steep, even if the investment pays off over time. Thankfully, almost every solar company in the area provides financing options. Solar loans drastically decrease upfront costs in most cases, but they also result in higher prices over time because of interest.However, the interest on solar loans also adds to your overall costs, so it’s important to include that in your estimate as well. You can always lower the total you pay in interest and possibly even your APR by making a larger down payment.
Solar Panel Installation Company
The solar installer you go with to handle your switch to solar energy can play a part in your total costs. There are about 3 solar panel companies in Antioch, and each can charge varying amounts for labor and equipment.You may notice national solar installers that have lower prices due to their bigger brand name and access to bulk pricing, or you might see small, local installation companies offering deals or promotions to compete with those larger companies.
