Factors that Affect Solar Panel Costs in Lake Mathews

For many Lake Mathews homeowners, the decision to install a solar energy system comes down to cost. However, the range of solar installation costs can be quite wide in Lake Mathews, with typical prices between $20,000 to $40,000. There are numerous factors that considerably influence the price you'll pay, which we'll go over below.

Solar Equipment

System size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of installing solar panels. That's why it's crucial to accurately ascertain the size of the solar energy system needed for your home by figuring out your average 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 brand name like Tesla or SunPower, these are often more expensive than other brands. Efficiency also matters. Whether you're opting for high efficiency because you have limited roof space or just want maximum energy production, you can expect 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 installers in Lake Mathews provide solar loans, which reduce your upfront costs of installing solar. 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're only able to 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 securing a solar loan with a low interest rate could reduce your costs considerably.

Solar Panel Installation Company

A final factor to consider when trying to figure out the cost of solar for your home or business in Lake Mathews is the company you get to install your PV system. Similar to choosing a company to install new cabinets, for instance, you'll have no shortage of solar installers that provide a range of services for different budgets. The company's size sometimes plays the most considerable role in the cost. Larger national companies, like SunPro and Sunrun, often have lower pricing because of access to 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 names.

How to Save on Solar Panels

There are a lot of solar installers to choose from, all of which offer different warranties, solar panel models and price points. To help you pick the right company for you, here are some tips to keep in mind:

  • Reputation: Make sure your solar installer has a good reputation by confirming it has certifications and licenses, checking its work history and reading reviews by past customers and solar experts like EcoWatch.
  • Solar Panel Brands: Not all solar companies have the same brands of solar panels, so the brand and type of panel you want can play a considerable role in the company you go with.
  • Contract: Before signing a contract with a solar installer, make sure you read it through completely so you understand the terms. Also, ask questions if you're not certain about some of the terms, such as what the warranty covers and if there are any guarantees about energy production.
  • Warranty: Companies typically offer different types of warranties that cover different things. A 25-year, all-inclusive warranty is the gold standard.

EcoWatch's Lake Mathews, CA Solar Cost FAQs

How much does it cost to install solar panels in Lake Mathews?

This is a hard question to answer precisely, because the cost depends on a few different 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. You can expect to pay more if you want extra solar equipment or more efficient panels, or if you have higher-than-average energy usage. Conversely, you can spend less if you choose a smaller solar panel system or cheaper solar panels.

Is cost the most important consideration when buying solar panels?

The upfront cost is a key factor to consider, but whether it's the most important for you depends on your goals for going solar. In places where rooftop space is limited, efficiency can be more important than the cost. Other factors that are important to consider are the quality and durability of your solar panels.

Can you sell solar power back to the grid in Lake Mathews?

Most states have net metering programs of some kind. Through these, you can either get paid for the extra power your system produces 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 many solar panels do I need to power my home?

To figure out what solar panel system size you need, you should find out how much energy your home uses and how much sunlight your home gets. For a general estimate, however, since each panel can generally produce about 250 to 400 watt-hours per hour, the average house will need 20 to 35 panels.
