Factors that Affect Solar Panel Costs in Castroville
There are many criteria that can affect your total installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar panels.
Solar Equipment
When it comes to estimating the cost of a solar system in Castroville, one of the most important factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are primarily based on your home’s energy consumption, which you can figure out by looking at past energy bills. Your total cost can increase by about $3,470 for each additional kilowatt you need.The brand and kind of equipment you choose 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 come at a higher price 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 more savings over time. Plus, if you want extra equipment like an electric vehicle charger or solar batteries, this will also raise the cost.
Solar Financing Terms
If paying for solar panels in cash is out of reach, solar loans are a popular option because they cut back your upfront costs and allow you to pay for your system over a term of, on average, between five and seven years.However, the interest on solar loans also adds to your total costs, so it’s vital to include that in your estimate as well. You can always reduce the total you pay in interest and possibly even your APR by making a larger down payment.
Solar Panel Installation Company
Finally, the company you opt for to install your solar system can play a role in determining your pricing. Castroville’s solar companies all have different labor costs and add varying upcharges to equipment. You may notice national solar installers that have lower prices because of their larger brand name and access to bulk prices, or you might see small, local installation companies offering deals or specials to compete with those larger companies.
