Factors that Affect Solar Panel Costs in San Lorenzo

Although the average cost of a solar system in San Lorenzo is $5,752, your actual cost may be above or below the average. There are many factors that can have a significant impact on the cost of a solar panel installation. Below are some of the more crucial things to keep in mind.

Solar Equipment

The size of the solar energy system you need for your home, 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 nearly $2,730. There are many different solar panel brands and the one you pick also changes the cost. Usually, the brands that offer higher efficiency tend to also be more expensive. Plus, the type of equipment you want to install can affect your total cost. If you only need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

Most solar installers in San Lorenzo have solar loans, which reduce the initial cost of installing solar. It's a good idea to include the interest you'll pay in your final cost estimate. If you can afford to put more money down upfront, 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 figure out the cost of solar for your home or business in San Lorenzo is the company you hire to install your solar panel system. As with choosing a company to renovate your kitchen, for instance, there are plenty of solar installers that provide a range of services at different costs. Additionally, some companies in San Lorenzo know more about local solar incentives and can help you make good use of additional rebates or tax exemptions. Though, they may charge more for that service. Even if they cost more upfront, they could help you save more money in the long run.

How to Save on Solar Panels

The solar panel company you choose will be a major factor in determining not only your total costs, but also the types of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are several important things you should take into account, such as:

  • Warranty: A comprehensive, long-term warranty can help keep your solar panels running smoothly and save you money on repairs and maintenance.
  • Reputation: Make sure your solar system installer has a good reputation by confirming it has certifications and licenses, checking its work history and reading reviews by previous customers and solar experts like the EcoWatch team.
  • Contract: It's important to look over your solar installer's contract fully to understand what services they will provide, what the warranty covers and what expectations you should have about the installation process.
  • Solar Panel Brands: The kind of solar panel you need plays a role in which installer you should choose, since different companies provide different panels.

EcoWatch's San Lorenzo, CA Solar Cost FAQs

What is the average cost of installing solar panels in San Lorenzo?

This is a tough question to answer exactly, because the cost depends on many factors. Generally speaking, it costs about $13,650 for a 5-kW system and $27,300 for a 10-kW system after the ITC is applied. It will be more expensive if you want additional solar equipment or higher quality panels, or if you have above-average energy needs. On the other hand, you can spend less if you choose a smaller solar panel system or less expensive solar panels.

Is it better to lease or buy solar panels in San Lorenzo?

Leasing solar panels can be an attractive choice, because it usually 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 get the most savings.

Can solar panels significantly reduce my electricity bills?

It is possible to eliminate your electricity bills with solar panels, but for most homeowners in San Lorenzo, 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 contact a local solar installer to see how many panels can fit on your roof.

What solar power system size is right for my home?

To figure out how many solar panels you need, you need to know how much energy your home requires and how much sunlight your home gets. For a general estimate, however, since each panel can typically produce about 250 to 400 watt-hours per hour, the average home will need 20 to 35 panels.
