FAQ | Solar Union SF

Got questions? We’ve got answers.

1. What does $0 down mean?

It means you can install your solar system without paying anything upfront. With Solar Union SF, you start benefiting from clean energy right away and choose a payment plan that fits your budget — all while reducing or even eliminating your electricity bill from day one.

2. How much can I expect to save when I go solar?

Savings vary depending on your location, usage, and system size. Most of our customers save between 20% and 40% on their energy bills in the first year and thousands over the life of the system. We’ll provide you with a personalized savings estimate before installation.

3. Is my home a good fit for solar?

Most sunny roofs with minimal shade work well. During our free consultation, we assess your roof’s angle, size, material, and condition, as well as your household’s energy needs, to design the perfect system for you.

4. What happens on cloudy or rainy days?

Your panels still generate electricity — just at a reduced rate. The rest of your energy comes from the grid or your battery backup, so you’ll have a seamless supply of power no matter the weather.

5. How does the battery backup work?

During the day, your solar panels power your home and store extra energy in the battery. If the grid goes down, the battery automatically activates in less than a second, keeping essential appliances and devices running.

6. Will my system work during a power outage?

Yes — with a battery backup. Without a battery, solar systems are required by law to shut off during outages for safety reasons. With a Solar Union SF battery, you stay powered day or night, even during emergencies.

7. What kind of maintenance is required?

Our systems are designed to be low-maintenance and long-lasting. We recommend an occasional rinse to remove dust or debris and a professional inspection every 2–3 years. All Solar Union SF systems come with a 25-year performance warranty for peace of mind.

8. What happens during installation?

We handle everything — permits, design, installation, and grid connection. The process usually takes 1–3 days on-site, depending on system size. Our installers are certified professionals who work quickly and leave your home clean

9. Do I need to change my roof?

Not always. If your roof is in good condition and has more than 10 years of life left, installation can proceed as-is. If repairs or replacement are needed, we’ll coordinate so your system is ready for decades of use.

10. What happens if I sell my home?

Solar can increase your home’s resale value. You can transfer your solar agreement to the buyer or pay off the system and include it in the home price. We assist with all the paperwork to make it smooth and stress-free.
