Peak demand charges can cause 50% of your energy costs .*
These energy spikes are avoidable. They can cost you hundreds to thousands of dollars every month.
*Power companies meter electricity in two ways:
• Consumption. This is your total energy use during the month (like the total number of miles you drove).
• Demand. This is the largest capacity you required over the month at any given time (like the highest speed you drove).
The consumption meter, the odometer, measures in kilowatt-hours. You pay X cents per kWh. The demand meter, the speedometer, measures in kilowatts. You pay X dollars per kW. Your utility's rate for both consumption and demand can vary. The rate depends on time of day, season, tiers of capacity/use and so forth.
If the printer kicks in at the same time as the air conditioner, you have a spike in demand. The utility company charges you based on that peak demand. This holds true even if you don't need that much power again the rest of the month. The utility exacts a fee for the overhead of ensuring this large amount of power is available to you at any time during the month. This extra fee is the peak demand charge.
An advanced energy storage and management system (AES or smart battery system) counteracts this. An AES evens out your demand from the utility. It draws power from the grid during the night and deploys power when your demand spikes. A smart battery system keeps instantaneous power in reserve to handle these spikes. It pushes your demand down to a monthly average, capping your demand charge.
When you combine AES with a solar PV system, you reduce your consumption from the utility. This manages your demand charges, something that solar can't do on its own.
The price tag? Less than you might think. And it pays for itself in as little as 18 months.
The payoff? Much greater control and much greater savings.
Advanced energy storage and management systems work in money-saving ways. They integrate lithium ion batteries with predictive learning load controllers. They use real-time data on your power demand and consumption. They charge or discharge in strategic ways.
When the grid is working, the batteries charge at night and release at peak times during the day. This evens out demand peaks. When there is a grid outage, the solar PV powers the building and charges the batteries. The batteries then deploy at night to provide power to essential systems until sunrise.
AES evens out your demand from the grid. This, in effect, cuts off the peaks.
Your solar PV system will take a big bite out of your demand during daylight hours. This reduces your energy demand charges significantly.
We selected SmartStorage from Sharp as our smart battery system of choice. Why? Because it's, well, smarter than the rest.
This smart battery system has a 10-year performance guarantee. It also offers Sharp's 100+ years as a product innovator. This system uses sophisticated predictive controls to manage the release of energy. It increases efficiency and saves you money.
SmartStorage keeps instantaneous demand power in reserve. As your demand starts to spike, SmartStorage load controllers trigger a rapid power discharge. This offsets the spike and caps demand.
SmartStorage from Sharp doesn't just store energy for use as backup. It also manages energy using precise and efficient methods. SmartStorage from Sharp is superior to systems like the Tesla Powerwall. As a backup power source, Powerwall and the like are not much different from a generator. By contrast, our AES advanced battery products use real-time data. They use this data to determine when to charge and when to discharge. And when comparing cost, don't forget Powerwall's price tag. Powerwall has installation costs. It also needs a special inverter to connect the DC Powerwall with your home's AC. With SmartStorage, you won't need any other equipment.
State-of-the-art equipment: Lithium ion batteries from Samsung.
Open customer access: Real-time Internet access and monthly performance reports. Online monitoring enables you to watch your system's performance. Automatic reports send to Sharp 24/7 status updates for maintenance.
Guaranteed performance: All equipment is under warranty for 10 years. Sharp also provides free maintenance and service. Sharp promises customers an annual demand charge reduction. If customers do not get this, Sharp will pay the difference!
SmartStorage can be used on its own or with a solar PV installation.
SunGreen can help you find the smart battery system that's best for you as a stand-alone. At your option, you can choose to add one to a solar PV system, to get an even greater return.
