Build a Sustainable Future

Why Commercial Solar in Los Angeles?

California is a prime location for businesses to reap the rewards of commercial solar power. Here’s why:

Significant Cost Savings

California has some of the highest electricity rates in the country. Solar panels dramatically reduce dependence on the grid, leading to substantial long-term savings on electricity bills.

Protection from Rising Rates

Electricity prices tend to fluctuate, but solar power provides a predictable energy source, shielding businesses from the impact of rising grid prices.

Increased Property Value

Commercial buildings with solar panels are increasingly attractive to tenants and potential buyers, which can boost property value.

Sustainability and Environmental Benefits

Solar power is a clean and renewable energy source, reducing a business’s carbon footprint and enhancing its reputation as environmentally conscious.

Energy Independence

While still connected to the grid, businesses with solar generate their own power, promoting a level of energy independence.

Financial Incentives

California offers a robust package of financial incentives to encourage solar adoption. This includes federal tax credits, property tax exclusions, and financing options like PACE which significantly reduce installation costs.

California Commercial Solar Incentives

Take a look at some of the incentives in place in California that make commercial solar power installations more affordable for businesses:

Federal Investment Tax Credit (ITC)

This federal tax credit currently stands at 30% of the total system cost, including installation and equipment. It significantly reduces your federal tax liability.

Self-Generation Incentive Program (SGIP)

This state program provides additional tax credits when a solar battery is installed in conjunction with solar panels. The exact credit amount depends on the system size and location.

Property Tax Exclusion

When solar panels are installed on a property, they increase its value. This added value is excluded for property tax calculation purposes through 2024.

Property Assessed Clean Energy (PACE) Financing

This commercial solar financing program allows property owners to finance solar installations through a voluntary property tax assessment, potentially making the project more affordable.

Renewable Energy Self-Generation Bill Credit Transfer (RES-BCT)

This program, designed specifically for local governments and college campuses that own or operate a qualifying renewable energy generation facility, to export excess power to Southern California Edison’s grid and receive bill credits in return.

Solar Billing Plan for Businesses

California Solar Billing Plan for businesses compensates commercial solar energy producers based on the time of day they export electricity to the grid, encouraging generation during peak demand hours. This shift aims to improve grid reliability while still offering businesses financial benefits from solar power.
