Solar Roof Tiles and Battery Storage: The Perfect Pair

Two Birds, One Solar Roof

You’re finally ready to go ahead and get that new roof.

But that’s not all.

You’re also ready to take the leap and completely change the way you power your home. Look at both solar roof tiles and batteries to make sure you see the best return on your investment.

Two birds, one solar roof.

We all know going solar is good for your power bill, but there’s no reason they shouldn’t be great with solar battery storage.

Solar Battery Storage: What, How, and Cost

What is solar battery storage?

Instead of sending all the generated energy to the grid, the surplus energy is stored in the batteries for later use, such as during periods of low solar generation or power outages. This allows homeowners to maximize self-consumption of solar energy and have a reliable backup power source when needed.

How does solar battery storage work?

Battery storage systems for solar tiles typically consist of lithium-ion batteries, charge controllers, and inverters.

The charge controller regulates the charging and discharging of the batteries, ensuring their longevity and optimal performance. The inverter converts the direct current (DC) energy stored in the batteries into alternating current (AC) electricity, which can be used to power household appliances. 

When solar panels or tiles produce more electricity than is being consumed, the excess energy charges the batteries. During times of low solar generation or high electricity demand, the stored energy in the batteries is discharged to power the home. Smart energy management systems can optimize the charging and discharging cycles based on energy usage patterns and electricity tariffs.

How much does solar battery storage cost?

The cost of battery storage for solar can vary depending on several factors, including the battery capacity, brand, technology, and installation requirements.

The cost of a residential solar battery storage system can range from a few thousand dollars to tens of thousands of dollars, including installation. However, it’s important to note that battery storage costs have been steadily decreasing over the years due to technological advancements and increased market competition.

Additionally, you need to consult with your trusted roofer about any local regulations on solar systems and products. They can also help you with some of the best financing options when it comes to installing a solar system with or without battery storage on your new roof.

The Perfect Complementary Technology

Benefits of Battery Storage in Your Solar Roofing System

Energy Independence: Battery storage allows homeowners to store excess solar energy generated during the day for use during nighttime or cloudy days.

By utilizing solar batteries in conjunction with solar roof tiles, individuals and households can become less reliant on outsourced utilities. They gain greater control over their energy production and consumption.

Backup Power: Even during outages, stored energy in the batteries provides a reliable and uninterrupted power source. Most grid-tied solar energy systems are designed to automatically shut down for safety reasons when the grid goes down. However, if you have a solar battery, it acts as a buffer.

Basic systems—lights, internet, refrigeration, other kitchen outlets, and garage—remain active for as long as possible based on the battery specifications and the home’s power requirements. Most last for 10-12 hours, but some can power a home for up to 18 hours. 

Time-of-use Optimization: By storing excess solar energy during off-peak hours and using it during high-demand periods, you can significantly reduce electricity costs. 

Standard electricity rates fluctuate on the supply-and-demand scale. You don’t want to fall victim to the price-guage.

Increased Self-Consumption: Traditionally, without battery storage, surplus solar energy would be fed back into the grid. 

This means homeowners would have to rely on the grid to meet their energy needs when their solar tiles couldn’t generate enough electricity during peak hours. If the excess is stored in the batteries, you can rely on your own power surplus without the extra bill.

Environmental Benefits: By reducing reliance on fossil fuel-based power plants, solar energy helps decrease the overall carbon footprint. Partnered with battery storage, which alleviates most reliance on the grid, energy has never been cleaner.

According to research, incorporating battery storage into solar systems could result in a significant reduction in carbon emissions, as high as 90% compared to traditional energy sources.

Long-Term Savings: While the initial investment might seem significant, the potential financial savings over the system’s lifespan make it a worthwhile endeavor.

With reduced reliance on the grid and lower electricity costs, you can recoup your investment in a relatively short period. 

Your property value will also see a boost as more and more homebuyers seek out eco-friendly features.

FAQ

What is solar battery storage?

Solar battery storage lets you store excess energy produced by your solar roof tiles for later use—like at night, during cloudy days, or during a power outage. It increases energy independence and reduces reliance on the utility grid.

---

How does solar battery storage work?

Your system includes lithium-ion batteries, a charge controller, and an inverter. When your solar roof generates more electricity than you use, the extra power charges the batteries. Later, that stored energy powers your home instead of drawing from the grid.

---

How much does solar battery storage cost?

Costs vary by battery size, brand, and setup—but expect anywhere from a few thousand dollars to over $10,000, including installation. The good news: prices are steadily dropping, and financing or incentives may be available through your roofer or local programs.

---

Why add batteries to a solar roof system?

Battery storage:

• Provides backup power during outages
• Helps you avoid high time-of-use electricity rates
• Increases self-consumption of your own solar power
• Reduces your carbon footprint
• Boosts your long-term savings and home value

---

Will solar batteries work during a power outage?

Yes—unlike grid-tied-only solar systems that shut off during outages, systems with battery storage can keep essentials running: lights, fridge, internet, and more. Runtime depends on your battery size and what you power—usually 10 to 18 hours.

---

Is battery storage worth the investment?

If you want energy independence, protection from outages, and lower long-term electricity bills, yes. Plus, you’re adding value to your home and contributing to a cleaner environment.
