Factors that Affect Solar Panel Costs in Vallejo
For many Vallejo homeowners, the decision to install solar panels rests on cost. However, the range of solar installation costs can be quite wide in Vallejo, with typical prices between $20,000 to $40,000. There are several factors that significantly influence the price you’ll pay, which we'll go over below.
Solar Equipment
One of the most significant factors to consider when it comes to the cost of installing solar panels is the size of the solar system, which is measured in kilowatts (kW). The more energy your household consumes, the larger your system will likely need to be. You can expect to pay about $3,470 per kilowatt in Vallejo.The solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you choose the most efficient solar panel brands, you’ll end up paying more upfront than if you opted for the most affordable panels. On the other hand, more efficient panels could save you more over time on your electric bills. Additionally, add-on products, like solar batteries, can bump up your total well above the Vallejo average.
Solar Financing Terms
If paying for a solar system out of pocket is out of reach, solar loans are a solid route because they decrease your upfront costs and let you pay for your system over a term of, on average, between five and seven years.Though solar loans make adopting solar energy more accessible for Vallejo homeowners, they can also add to the total you pay for your system due to interest. If you make a larger down payment, though, you can cut back on how much interest you have to pay.
Solar Panel Installation Company
The last key cost factor you should take into consideration is the installer you choose. Given the massive popularity of sustainable energy solutions in Vallejo, you’ll have a great number of options to choose from, but each comes at different price points for labor and equipment.Some companies 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 choose a company that has the products, warranties and services you’re looking for and also fit into your budget.
