Factors that Affect Solar Panel Costs in Altadena
There are several criteria that can determine your solar panel installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that does the installation.
Solar Equipment
The size of the solar panel system you need for your household, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, your total will most likely increase by nearly $3,470. The kind of solar panels and equipment you choose is another factor that will substantially influence costs. Solar panels that are more efficient, like monocrystalline panels, tend to come at a higher price. Further, solar equipment is more than just the solar panels themselves. You’ll also need to decide on the kind of racks used to mount the panels, inverters, solar batteries, etc. It’s important to take all of this into consideration when researching a solar system that’s in your budget.
Solar Financing Terms
Many homeowners find the average cost of solar in Altadena to be prohibitively steep, even if the investment pays off over time. Thankfully, almost every solar company in the area offers financing options. Solar loans greatly decrease upfront costs in most cases, but they also result in a higher cost over time due to interest.It’s a good idea to add the interest you’ll pay in your final cost estimate. If you can afford to pay a higher 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 pick will affect your total cost to make the switch to solar power. Different companies will charge different amounts for the equipment and labor.Additionally, some companies in Altadena are more knowledgeable about local solar incentives and can help you learn about additional rebates or tax exemptions. Though, they may charge more for walking you through the whole process. Even if they cost more upfront, they could help you save more money in the long run.
