Factors that Affect Solar Panel Costs in Lake San Marcos
The cost of installing a solar system in Lake San Marcos can vary by more than $10,000 from home to home. Your actual cost depends on several factors. The biggest one is your system size, and other factors include the equipment you choose, financing options and the solar installer you choose.
Solar Equipment
When it comes to estimating the cost of solar panels in Lake San Marcos, one of the most important factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are largely based on your home's energy usage, which you can determine by looking at past electricity bills. Your overall cost can increase by around $2,730 for each additional kilowatt you need. Some solar panel brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer better efficiency. In a city like Lake San Marcos, where sunlight is abundant, efficiency can quickly pay off. Also, if you have a small roof or you don't have a lot of space for your panels, higher efficiency options will be a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.
Solar Financing Terms
For some homeowners, paying for a solar system out of pocket can be difficult. Solar loans are offered by most installers in Lake San Marcos, which can bring down, or in some cases completely eliminate, your upfront costs to make solar more affordable. However, the interest on solar loans also increases your overall costs, so it's vital to keep that in mind as well. You can always lower the total you pay in interest and in some cases even your APR by putting more money down.
Solar Panel Installation Company
A final factor to consider 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 PV system. Similar to choosing a company to build a deck or pool, for example, you'll have no shortage of solar installers that provide a range of services for different budgets. You may come across 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 promotions to compete with those larger companies.

How to Save on Solar Panels
The company that does your solar panel installation will affect the warranties and brands you have access to, and it will also have an impact on your total cost. Since selecting a company can be a tough decision, we have some tips to help you, such as:
- Reputation: Solar system installers that have great reviews from their customers and that have been in business for many years most likely provide good-quality solar panel installation and expertise.
- Solar Panel Brands: Different companies will carry various brands and types of panels. If you know you want a specific brand, make sure the solar panel installer you're considering has it.
- Warranty: A comprehensive, long-term warranty can help keep your solar panel system running smoothly and save you money on part replacement and repairs.
- Contract: Before signing a contract with a solar company, be sure to read it through completely so you understand the terms. Also, ask questions if you're not sure about some of the terms, such as what the warranty covers and if there are any guarantees about energy production.

EcoWatch's Lake San Marcos, CA Solar Cost FAQs
What is the average cost of installing solar panels in Lake San Marcos?
The average cost of solar panels in Lake San Marcos is about $13,650 for a 5-kW system and $27,300 for a 10-kW system before the ITC, but the actual cost will depend on things such as the kind of solar panels you want, what size system you need and how much energy you use.
Is it better to lease or buy solar panels in Lake San Marcos?
Leasing solar panels can be an attractive choice, because it commonly 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 incentives and your home value won't increase. Buying solar panels is a better way to go if you want to get the most savings.
Does Lake San Marcos have a net metering program?
The majority of states offer net metering programs of some kind. Through these, you can either get paid for the extra power your system generates or or receive credits to put toward future utility bills. Currently there are just three states that don't have any net metering laws: Alabama, Tennessee and South Dakota.
How often do you have to replace solar panels?
On average, solar panels can last about 25 to 30 years. Some even last up to 50 years, but their efficiency decreases by about 0.8% each year. You can choose to replace them sooner if you want to maintain a higher amount of energy production.
