Factors that Affect Solar Panel Costs in Lake San Marcos
Cost is typically one of the most important factors for homeowners considering investing in solar. There are a few key factors that will push your cost above or below the average in Lake San Marcos: solar equipment and system size, financing options and the solar installation company you choose. We’ll cover each of these briefly below.
Solar Equipment
The size of the solar panel 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, you can expect your total to increase by around $3,470. The type of solar panels and equipment you want is another factor that will significantly impact costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to cost more. Moreover, solar equipment consists of 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 looking into a solar system that falls within your budget.
Solar Financing Terms
If paying for solar panels out of pocket is out of reach, solar loans are a solid choice because they decrease your upfront costs and let you pay for your system over a term of, on average, between five and seven years.It’s wise to add 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 the amount of time it’ll take to pay back the loan.
Solar Panel Installation Company
A final consideration when trying to estimate the cost of solar for your home or business in Lake San Marcos is the company you hire to install your solar panel system. As with choosing a company to install new cabinets, for instance, there’s no shortage of solar installers that offer a range of services for different budgets.You may see national solar installers that have lower prices due to their bigger brand name and access to bulk prices, or you might see small, local installation companies offering deals or promotions to compete with those major players.

EcoWatch's Lake San Marcos, CA Solar Cost FAQs
How much does it cost to install solar panels in Lake San Marcos?
The average cost of solar panels in Lake San Marcos is about $17,350 for a 5-kW system and $34,700 for a 10-kW system before the ITC, but the actual cost will depend on certain factors like the model of solar panels you want, what size system you need and how much energy you consume.
Is it better to lease or buy solar panels in Lake San Marcos?
Leasing solar panels can be an option if you can’t afford to pay upfront or secure a solar loan, but since you don’t own the system, you can’t take advantage of many solar incentives. Also your property value won’t increase, so you’ll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most bang for your buck from going solar.
Is switching to solar power worth it?
Solar panels can be a great investment for most homeowners, but they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight and/or your energy bills are already pretty low, solar panels might not be for you.
What solar power system size is right for my home?
The exact number of solar panels you need depends on your household energy needs and how much sunlight your roof gets. You can look at your energy bills for the past year to get an idea of the solar system size you'll need. The average household has to buy between 20 and 35 panels to account for their typical energy usage.
