Factors that Affect Solar Panel Costs in San Marino
There are a number of factors that can influence 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
System size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of going solar. That’s why it’s a priority to accurately assess the size of the solar energy system needed for your home by figuring out your typical energy use.The brand and type of equipment you want for your solar system can increase or decrease 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 will be looking at a higher equipment cost, but this can typically lead to greater savings over time. Plus, if you want additional equipment like an electric vehicle charger or solar batteries, this will also increase the cost.
Solar Financing Terms
Most solar companies in San Marino provide solar loans, which reduce the initial cost of installing solar panels.When considering your overall cost, you should also calculate the interest you’ll pay if you decide on a solar loan. Also, paying more upfront can reduce the total interest paid over time.
Solar Panel Installation Company
Lastly, the company you choose to install your solar system can affect your pricing. San Marino’s solar companies all have different labor costs and add varying upcharges to equipment. Larger national companies typically have lower costs, but some local companies undercut them by offering sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or add-on services like electric vehicle charger installation, they might be cheaper overall.

EcoWatch's San Marino, CA Solar Cost FAQs
How much does it cost to install solar panels in San Marino?
This is a tough question to answer exactly, because the cost depends on many factors. Broadly speaking, it costs about $17,350 for a 5-kW system and $34,700 for a 10-kW system after the ITC is applied. It will cost more if you want additional solar equipment or higher quality panels, or if you have higher-than-average energy consumption. Conversely, you can spend less if you choose a smaller solar panel system or less efficient solar panels.
Should I lease or buy solar panels in San Marino?
Leasing solar panels can be an option if you can’t afford to pay upfront or get a solar loan, but since you don’t own the system, you don’t have access to 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.
Can solar panels completely eradicate my electricity bills?
It is possible to eliminate your electricity bills with solar panels, but for most homeowners throughout San Marino, that will require at least a 10-kW system. Not all homes will have roofs that can accommodate that size system, so you’ll want to check with a local solar installer to see how many panels can fit on your roof.
How many solar panels should I get to power my home?
To figure out what solar panel system size you need, you should find out how much energy your home needs and how much sunlight your home gets. For a general estimate, however, since each panel can usually produce about 250 to 400 watt-hours per hour, the average household will need 20 to 35 panels.
