Factors that Affect Solar Panel Costs in Lafayette
For many Lafayette homeowners, the decision to adopt solar energy comes down to cost. However, the range of solar installation costs can be quite wide in Lafayette, 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 cost of solar panels varies by thousands of dollars due to a variety of factors. One of the major factors is the system size, which is measured in kilowatts (kW). Solar power systems that have higher efficiency or power production use better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $2,730. The model of solar panels and equipment you choose is another factor that will largely affect costs. Solar panels that are more efficient, 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 make decisions about 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 for a solar system that falls within your budget.
Solar Financing Terms
Most solar companies in Lafayette have solar loans, which reduce the initial cost of installing a solar system. You'll have to consider the long-term cost of loans, including the amount of 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 interest rate could reduce your costs considerably.
Solar Panel Installation Company
The solar installer you go with to handle your switch to renewable energy can have an effect on your total costs. There are about 3 solar installation companies operating in Lafayette, and each can charge varying amounts for labor and equipment. The size of the company can sometimes play the most considerable role in your total costs. Larger national companies, like SunPro and Sunrun, often have lower prices because they have more resources and better pricing. Smaller local companies might be more costly, but they can sometimes have better customer service and more customization options, and the occasional sale or discount can bring their pricing lower to compete with bigger companies.

How to Save on Solar Panels
There are many companies to choose from in Lafayette, and some homeowners feel overwhelmed considering their options. Picking the right company for you can be tough, so here are some tips to help you decide:
- Warranty: A comprehensive, long-term warranty can help keep your solar panels running for years to come and save you money on repairs and maintenance.
- Reputation: Companies that have been in business for many years likely have a high reputation. This is important because it ensures that it will not only see your solar project through, but will also provide adequate aftercare and customer service, such as part repairs and replacements.
- Solar Panel Brands: The brand of solar panel you want to get plays a role in which company you should choose, since different companies provide different panels.
- Contract: When looking through your solar installer's contract, ask for clarification about any terms you're not sure of and make sure you understand what happens in scenarios like a system component breaking or the company going out of business.

EcoWatch's Lafayette, CA Solar Cost FAQs
How much does it cost to install solar panels in Lafayette?
The average cost of solar panels in Lafayette is about $13,650 for a 5-kW system and $27,300 for a 10-kW system before the ITC, but the real cost will depend on stuff like the kind of solar panels you want, what size system you need and how much energy you consume.
Should I lease or buy solar panels in Lafayette?
Leasing solar panels can be an option if you can't pay upfront or secure a solar loan, but since you don't own the system, you don't have access to many solar incentives. Also your home 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.
Does Lafayette have a net metering program?
Each state has some form of net metering programs except Tennessee, South Dakota and Alabama currently. Some states let you sell power back to the grid, but others just offer you credit toward your future energy bills.
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 uses 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 household will need 20 to 35 panels.
