What Determines the Cost of Solar Panels in Mariposa County, California?

There are several possible factors that may influence the cost of one’s solar panels in the county. They range from size of the panel to the method in which they were installed. Some of these factors include:

Type of Panel

Most solar panels available today are of 3 different types. They include Monocrystalline solar panels, Polycrystalline solar panels, and thin film solar panels. Each of them have different features, making them vary in price. Some of them are more efficient than the others, but generally cost more. The type of solar panel you should get can depend on your energy needs and the peculiarities of your environment.

Brand of Panel and Solar Equipment

Naturally, some brands are more popular than others and have made a name for themselves in the market. This can often influence their pricing, causing their products to be sold at a premium compared to other brands. More popular panel brands are often more reliable, and are well known for a reason.

Levelized Cost of Energy

Levelized Cost of Energy (LCOE) in a nutshell, is a measure of all of the costs of a system. It includes costs such as buying the system, running the system, how long the system lasts, etc. It essentially measures all of the costs of a system in the long run. This allows you to compare the prices of different energy supply systems and determine which one will benefit you the most in the long term.

Price Per Watt

Price per watt is a more precise measure of the cost of a solar system. It is obtained by dividing the cost of the system by the amount of energy it produces. So for example, if a system is estimated to cost around $30,000 for 10kW (10,000 watts), then the cost of the system is $3 per watt. Cost per watt or price per watt, and Levelized cost of energy are similar, however, a major difference is that price per watt does not include the system’s maintenance costs.

Installation Company

The installation company that fixes your solar system up for you might influence your eventual markup. Installation companies have employees of different kinds, with some having more expertise and certifications than others. This allows them to charge a premium and can increase the costs by quite a bit.

Other factors which might increase the installation company’s prices are the size of the company, and the location.

The company or solar provider allows the customer to purchase the power generated at a fixed rate depending on their system’s energy output. These agreements often last for a period of 10 to 25 years, and the provider covers all maintenance and financing costs related to the system during this time.

What are Solar Leases?

A solar lease is another option that allows homeowners to utilize solar systems for little to no upfront costs. Solar leases bear some similarities to Solar Power Purchase Agreements. With solar leases, the solar provider retains ownership of their equipment as well. The difference between the two is that unlike in PPAs, the monthly payment rates do not depend on the value of the energy generated.

What are Solar Loans?

Solar loans are typically loans used to finance solar systems. A solar loan may be gotten from a bank, money lender, or a solar company.
