The Tesla Powerwall 2 is one of the best solar batteries available and has a capacity of 13.5 kWh. One benefit is that the Tesla Powerwall 2 is an AC-coupled battery.

Sunlux Warranty

Sunlux solar Cost

The best way to get a price on a Sunlux solar energy system is to contact the company for a solar bid. Prices vary in different markets and by equipment. For example, solar panel systems with battery storage will cost more than those without batteries.


Sunlux Payment Options

Sunlux offers solar PPAs, leases, pre-paid leases, and ownership. This means that there are various payment options, including cash and $0 down financing. 


If you purchase your solar energy system instead of leasing it or entering a PPA, you are eligible for the federal solar tax credit if it is on your primary or secondary residence. However, if you enter a solar PPA or lease, you are not eligible for the federal tax credit, most state incentives, or utility rebates.

In addition, many states, local governments, and utility companies in California and Texas offer solar incentives. Refer to the Database of State Incentives for Renewables and Efficiency (DSIRE) for more information.

For example, the Self-Generation Incentive Program (SGIP) provides rebates to California homeowners that install energy storage. This is an excellent way to have power during blackouts and promote resiliency.

How does Sunlux’s installation process work?

Going solar starts with a solar evaluation that includes roof measurements and shading analysis. Next, a Sunlux solar expert designs the solar panel system for maximum energy performance and utility bill savings. Then, Sunlux applies for all the necessary permits to move the project forward. Finally, the city inspects the solar system and ensures it is up to code. 

Sunlux Solar Customer Service
