Top Reasons Why You Should Use Solar-Powered Batteries

If you’ve recently installed a solar power system in your home or business, or are considering solar power options, then some of the questions you’ve faced include, ‘should I include a solar-powered battery, and if so, why?’  Here are a few reasons why you should use solar-powered batteries:


  1. Solar-powered batteries maximize access to your solar power.

  • During peak sun times, your solar power system will make more energy than you need. A battery lets you keep any excess energy for use when it’s overcast and in the evening.

  1. Solar-powered batteries provide a clean power back-up plan.

  • When the power goes out, you can draw stored energy not only from your solar power system but also from your battery.

  • Unlike gas generators, solar-powered batteries deliver energy without greenhouse emissions.

  1. Solar-powered batteries help control utility costs.

  • The power grid is usually busiest between 4 pm and 10 pm and utility companies may charge higher rates based on these use times. Batteries can be used during peak times to avoid using higher-priced energy.

  • And if needed, batteries can charge from the grid overnight when rates are usually cheapest.

  1. Solar-powered batteries are reliable and safe.

  • Initially, solar-powered batteries were susceptible to shifts in temperature, losing functionality in very cold or very hot weather. But the development of lithium and vanadium flow batteries for solar power systems now allows use across temperatures ranging from below zero to desert heat.

  • The structure of these newer batteries, particularly the vanadium flow options, eliminates risks associated with lead-based or lithium-ion batteries. Lithium is performing badly in charging and discharging at below freezing. Our batteries have a built-in system to keep temperatures within an ideal range. But lithium ion is required to be installed in a temperature controlled environment.

  1. Solar-powered batteries are lasting, making them cost-effective.

  • Batteries can lose the ability to charge and recharge, requiring a new battery or additional batteries to get needed capacity. But battery storage capabilities have improved, with new developments helping batteries deliver up to 100% of their capacity over time. Lithium batteries still suffer from fast decay and loss in capacity over time (e.g., your mobile phone). The good news is that vanadium flow, a type of rechargeable flow battery, does not decay. 

  • Technological advancements in structure and design have extended battery life to up to 25 years. While this statement is true for vanadium flow vanadium flow, lithium suffers from decay. The life of lithium can be in excess of 10 years but with a big loss in capacity. Vanadium can last for 25 years with no loss in capacity. 

When you commit to clean, solar energy, don’t miss out on the benefits of solar-powered batteries. Rest a little easier, and manage your energy expenses knowing you’ll have access to power whenever you need it – at night, during storms, and for all the years ahead.
