At SMVA Solar Company Houston, we understand the importance of reliable backup power solutions, especially in areas prone to power outages or for individuals seeking energy independence. One of our flagship products is a range of solar batteries designed to provide seamless backup power when you need it the most. We'll explore the various types of solar batteries we offer and help you make an informed choice for your backup power needs.


  1. Lithium-Ion Batteries: Lithium-ion batteries are renowned for their high energy density, long lifespan, and rapid charging capabilities. They are an ideal choice for homeowners looking for a dependable and efficient backup solution. Our lithium-ion batteries come in various capacities to suit your specific requirements.

  2. Lead-Acid Batteries: While not as advanced as lithium-ion batteries, lead-acid batteries are a cost-effective option for backup power. They are durable and can handle repeated charge and discharge cycles. These batteries are available in both flooded and sealed varieties.

  3. Flow Batteries: Flow batteries are gaining popularity due to their scalability and ability to store vast amounts of energy for extended periods. They are excellent for off-grid applications and areas with unreliable grid access.

  4. Nickel-Iron Batteries: Nickel-iron batteries are known for their longevity, with a lifespan of up to 30 years. They are highly robust and can withstand extreme environmental conditions, making them a favorite for remote and rugged locations.

  5. Saltwater Batteries: Saltwater batteries are an environmentally friendly option, utilizing non-toxic materials. They are safe, easy to maintain, and have a relatively long lifespan.


At SMVA Solar Company Houston, we offer a diverse range of solar batteries to cater to your backup power needs. Our expert team can help you choose the best solution based on your energy requirements, budget, and environmental preferences. With our solar batteries, you can enjoy uninterrupted power during outages while contributing to a sustainable energy future.

To size your solar battery backup system accurately, start by evaluating your energy consumption patterns. Analyze your past electricity bills to understand your daily and seasonal energy usage. This data will serve as a foundation for estimating the battery capacity required to keep your home powered during cloudy days or power outages.


Next, consider your solar panel system's capacity. The size of your solar array influences how quickly your battery can recharge. A larger solar array can replenish your battery more rapidly, reducing the need for excessive battery capacity.


Factor in your desired level of energy independence. If you want to be completely self-sufficient during extended power outages, you'll need a larger battery bank. On the other hand, if you're content with partial backup power, a smaller battery may suffice.


Evaluate the climate in your area, as it impacts solar generation. Locations with frequent overcast skies may require larger batteries to compensate for reduced solar input.


Consult with a reputable solar installer or use online calculators to fine-tune your battery size calculation, considering factors like battery chemistry, depth of discharge, and efficiency losses.


Sizing your solar battery backup system appropriately ensures you have adequate energy reserves when you need them, promoting energy efficiency, cost savings, and peace of mind.

How to Size Your Solar Battery Backup System

Integrating Solar Battery Backup with Grid-Tied Solar Panels

The integration of solar battery backup systems with grid-tied solar panels represents a significant advancement in the realm of renewable energy technology. This innovative approach combines the benefits of traditional grid-tied solar systems with the reliability and energy resilience of energy storage.


At its core, a grid-tied solar panel system generates electricity from sunlight and feeds excess power back into the grid, offsetting energy costs and reducing dependence on non-renewable sources. However, this reliance on the grid means that when the grid experiences outages or disruptions, solar panels alone cannot provide power to the home. This is where solar battery backup systems come into play.


By seamlessly integrating solar batteries with grid-tied panels, homeowners can store excess solar energy during the day and use it during the night or during power outages. This setup not only maximizes self-consumption of solar energy but also provides a reliable source of backup power, ensuring that critical appliances and essential systems remain operational when the grid is down.

Such integration promotes energy independence and reduces reliance on fossil fuels, making it a sustainable choice for homeowners looking to minimize their carbon footprint. Additionally, these systems often offer smart energy management features, allowing users to optimize their energy usage, further reducing electricity bills.


The integration of solar battery backup with grid-tied solar panels represents a dynamic shift towards a more resilient, sustainable, and cost-effective energy future. This technology empowers homeowners to harness the full potential of solar energy while ensuring uninterrupted power supply, fostering a greener and more reliable energy landscape.
