Batteries and other emerging technologies are dramatically expanding the effectiveness of a typical solar energy system by giving homeowners and business the flexibility to create and use power when and how they want.
Between 2007 and 2014, there was an estimated $17.4 billion in private R&D investment for energy storage technology alone. Advancements are happening quickly, and prices are dropping.
When it comes to batteries, price and capacity are key. You must be able to store enough electricity to power your home or business around the clock (capacity), at a price on par, or lower than you can buy that same amount of power from your local utility.
Determining how much capacity you need requires a detailed examination of many variables, including: physical structures, efficiency of major power loads, consumption patterns, as well as how many systems you wish to take off-grid and for how long. It’s an extensive set of variables that can have a dramatic impact on how many batteries you need to buy.
What’s more, businesses use power very different than home owners. As such, energy storage systems are somewhat different for each application.
It's almost a year later now and my summer bills have gone from $425 at the highest summer month a year ago to $180 at my highest summer month now. On average I'm saving about 65% off my old bills.
Storing energy in batteries is just one way to expand the potential of your solar energy system and save money.
A demand manager is a smart device that stabilizes your overall energy consumption by carefully cycling a pre-selected list of large electric loads on and off during peak pricing hours. This process – known as peak shaving - allows you to better control your energy costs by avoiding the demand spikes that occur when numerous, high-energy devices cycle on at the same time.
Demand managers are particularly effective at squashing monthly demand fees—such as those introduced by SRP in 2015.
