Incentives, Tax Credits & Rebates For San Jose Solar Panels


Undoubtedly, investing in solar panels is an important financial decision as it costs a lot. However, it is a good decision compared to how much can be saved from electricity bills.

There are incentives set up in San Jose and California to promote the switch from fossil fuels to solar panels and renewable energy. Here are five incentives for locals who plan to switch to renewable energy in San Jose.

Investment Tax Credit (ITC)

The most significant incentive to invest in solar energy is the 30% federal tax credit. This incentive allows you to deduct 30% of the cost of installing a system from your federal tax. The ITC was established in 2005. Despite challenges, its progress and impact have sustained it.


California Public Utilities Commission

These incentives come in two forms: ‘No Cost Solar For Low-Income Residents’ and a solar incentive for affordable multifamily housing. Property owners would have to apply on the waitlist to get funding for a solar energy system to get these incentives.

Property Assessed Clean Energy (PACE)

This is a loan option for property owners to finance their solar energy investments through property taxes. In this program, local or state governments work with financers to pay the bill of the solar system for the property owners upfront, and the owners would, in turn, pay an increased property tax bill for an average of 20 years as payback.

Property Assessed Clean Energy is available for Residential Properties (Residential PACE or R-PACE) and Commercial properties (Commercial PACE or C-PACE).

Single-family Affordable Solar Homes Program (SASH)

This program makes available incentives for low-income single-family owners to pay the cost of installing solar.

Solar Power Purchase Agreement (PPA)

With this incentive program, property owners only have to pay the cost of electricity installed panels generated every month but with $0 upfront to have the panels installed.

5 Things To Look Out For When Installing Solar Panels In San Jose


When installing solar panels, there are things to consider to ensure efficiency and optimum solar system use. They include


When installing a solar panel in any area, it is necessary to consider the weather. Since solar panels generate electricity from the sun, installing them in an area with more sunshine is better. Snow, rain, clouds, and fog hinder solar panels from working effectively. Having a battery bank is a good idea if the weather is not so favorable as it would help save excess power on sunny days.

Peak Hours

Peak Hours are the hours of the day when the sun shines the most. During these hours, the solar panel gets enough energy from the sun to generate heat. How long these peak hours last can also affect the electricity generation of the panels. In most places, while solar panels can trap heat in the morning and late afternoon, the peak hours are usually during noon.


Solar Panel Direction and Angle

If the solar panel is facing a direction or is at an angle where it cannot absorb energy from the sun, generating electricity could be a hassle. Usually, in the USA, solar panels are most effective when facing south due to the optimal azimuth angle in that direction.


Shading Elements

Another factor to consider when installing a solar panel is the presence of shading elements. Shading elements could be anything, such as chimneys that block sunlight from getting to the solar panel. If no sunlight gets to the panels, they won’t absorb heat to generate the needed energy.


Air pollutants, such as dust and other particulates, can affect the efficiency of solar panels. If the air pollutants are so intense, they could quickly stop the solar panels from getting sunlight.


Because San Jose is located in California, where the sun mostly shines, solar energy as a source of generating electricity is already being adopted by a high percentage of its over 1 million population. With an average of 257 sunny days and the advantages that solar panels come with, it is safe to say that solar energy is the next big turn for the city.
