Factors that Affect Solar Panel Costs in Larkspur
The cost of installing a solar system in Larkspur can vary by more than $10,000 from home to home. Your actual cost depends on several factors. The most significant one is the size of the system your home needs, and other factors include equipment choices, financing options and the solar installer you choose.
Solar Equipment
The cost of solar panels varies by thousands of dollars due to a variety of factors. One of the key factors is the system size, which is measured in kilowatts (kW). Solar power systems with greater efficiency or power generation use 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 $3,470.There are a lot of different solar panel brands and the one you pick also affects the cost. Typically, the brands that are more efficient tend to also cost more. Additionally, the type of equipment you want to install can affect your total cost. If you only need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.
Solar Financing Terms
If paying for a solar system in cash is out of reach, solar loans are a popular route because they lower your upfront costs and let you pay for your system over five to seven years on average.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 how long it’ll take to pay off the loan.
Solar Panel Installation Company
The solar installer you opt for to handle your switch to sustainable energy can play a part in your total costs. There are about 3 solar installation companies in Larkspur, and each can charge different amounts for labor and equipment.Additionally, some companies in Larkspur have more knowledge about local solar incentives and can help you take advantage of additional rebates or tax exemptions. However, they may charge more for that service. Even if they cost more upfront, they could end up saving you more money in the long run.
