Factors that Affect Solar Panel Costs in Westlake
For many Westlake homeowners, the decision to install a solar energy system comes down to cost. However, the range of solar installation costs can be quite wide in Westlake, with typical prices between $20,000 to $40,000. There are a number of factors that considerably influence the price you’ll pay, which we'll go over below.
Solar Equipment
The size of the solar energy system you need to offset your energy usage, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, your total will most likely increase by about $3,800. The type of solar panels and equipment you get is another factor that will considerably impact costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to come at a higher price. Plus, solar equipment is more than just the solar panels themselves. You’ll also need to consider the kind of racks used to mount the panels, inverters, solar batteries, etc. It’s important to take all of this into consideration when looking into a solar system that falls within your budget.
Solar Financing Terms
Solar panels can save you money on power bills over many years, but they can also be a big investment. That’s why many Westlake homeowners opt to finance their solar panel systems to offset upfront costs.You’ll have to consider the long-term cost of financing options, including the total interest you’ll pay over the length of the loan. If you can only get a high-interest loan, then your total can be hundreds or even thousands of dollars above the equipment and labor cost. Making a larger down payment or finding a solar loan with a low APR could reduce your costs considerably.
Solar Panel Installation Company
The last key cost factor you should consider is the installer you choose. Given the massive popularity of clean energy solutions in Westlake, you’ll have a great number of options to choose from, but each comes at varying price points for labor and equipment.Larger national companies generally have lower costs, but some local companies keep up with them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or add-on services like electric car charger installation, they might be cheaper overall.

EcoWatch's Westlake, LA Solar Cost FAQs
What is the average cost of installing solar panels in Westlake?
This is a difficult question to answer precisely, because the cost depends on a few different factors. Broadly speaking, it costs about $19,000 for a 5-kW system and $38,000 for a 10-kW system after the ITC is applied. You can expect to pay more if you want extra solar equipment or more efficient panels, or if you have higher-than-average energy consumption. On the other hand, you can spend less if you opt for a smaller solar panel system or cheaper solar panels.
Should I lease or buy solar panels in Westlake?
Leasing solar panels can be an appealing choice, as it often comes with low or $0 upfront payments. The downside is that you won’t be able to save as much. If you lease, you don’t own the system, so you can’t claim any tax rebates and credits and your home value won’t increase. Buying solar panels is a better option if you want to maximize your savings.
Is it worth going solar in Westlake?
Whether or not solar panels are worth it depends on a variety of factors like the cost of electricity near you and the amount of direct sunlight your roof gets.
How long do solar panels last in Westlake?
Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they should be disposed of at that time. What this means is how much energy they produce will have decreased significantly after that point. You can choose to replace them once you've had them for that long or you can continue to use them at a lower efficiency.
