Become self-sufficient by storing the Sun

Control where you get your power, when you use it, and how much you pay for it.

The Solar Battery Curve

Understanding the basics behind solar storage


Solar data has showed that the highest household consumption is reached during the early morning and evening hours. However, solar systems generate most of its energy during the day, PEAKING at mid-day under ideal conditions. Adding batteries to your solar system will allow you to store energy during the day and use it during the PEAK hours to offset high electricity prices, especially during the evening hours.

Storage Sweet Spot

Within the storage world, there is only one absolute: there is no "one-fits-them-all" solution.

 

The purpose and further outcome of each application will dictate what type of batteries best suits each particular situation. There are batteries better suited for those wanting to go off-the-grid completely versus some that are better suited for grid connected systems. For grid connected systems, batteries can be tailored to avoid demand or time-of-use charges , extend your solar window down into the evening hours and/or provide back-up to some loads during a grid outage.

 

Energy storage systems (ESS) are designed to provide a level of energy independence and savings that battery-less-solar-systems cannot accomplish alone.

The Hybrid Storage Solution

What is a hybrid system?

A hybrid system is basically a grid connected storage system that comes in a variety of names like energy storage systems (ESS), home-battery-storage, solar-backup. They all describe a range of home storage solutions for your home. They also might differ on how they're coupled and which battery technology is utilized, but they all have one thing in common, they are designed to give you a level of energy independence and control that solar alone cannot provide.

There is not a straight answer on how much storage you might need until some questions are answered:

  • Are you comfortable storing the excess energy during the day and use it to offset some evening demand? Are you OK with the grid supplying that which was not supplied by your batteries?
  • Or are you more comfortable with a storage system that provides enough power for the the full night?
  • Would you like the system to perform during a power outage?
  • Or would you prefer a modular system that can see expansion towards a full backup or even off-the-grid?

How much storage do I need?

What's your storage sweet spot?

Every storage solution out there is designed for a specific purpose. For example, we have the Lithium-ion Tesla Powerwall that operates at a high voltage versus the Iron Edison or Adara solutions that can operate at the low 12V, 24V and 48V ranges. Furthermore, what type of loads would you be running during storage operation dictates if your system needs to be built with energy or power consumption capabilities. It all boils down to the right technology, for the right application, at the right price.

The Off-Grid Solution

What is an off-grid system?

Off-the-grid systems, normally known as standalone power systems (SAPS), are systems disconnected from the local utility grid. The main purpose of these systems is to provide reliable power to complete households, businesses and even communities. They're able to store energy for multiple days (days of autonomy) to supply dedicated loads during periods where the Sun is unable to shine bright. These systems are coupled normally with natural gas or propane generators to accommodate high power consumers (i.e. furnace, AC)

Off-grid systems are by nature unique since each case is different from the next. The following steps are needed for a successful off-grid design

  • Load Profile: a detailed study of the loads to be powered by the off-grid systems needs to happen to understand the daily energy demand (Wh) the system will cover.
  • Days of Autonomy: how many cloudy days can the system support in a row without Sun?
  • System Main Voltage: a system voltage needs to be chosen. This are normally 12, 24 or 48V.
  • Storage Battery Capacity (Ah): after daily energy is calculated and system voltage is chosen, the amount of ampere-hours can be obtained to chose the right battery system.
  • Solar Panels: after the battery bank size has been calculated, number of solar panels needed are calculated based on winter sun-hours for your specific location.
