Environmental concerns

Disposable batteries contain harmful chemicals like nickel, lead and mercury that could pollute the environment. Rechargeable batteries also contain harmful elements but the reusability of these batteries prevents the frequent disposal of the same compared to that of disposable ones.

Longer lifespan, no maintenance, no gas emissions, deep lifecycles and less environmental impact definitely makes rechargeable batteries better than your old batteries.

These solar batteries are rated to deliver 5 kilo-watt hours kWh per cycle. Check your power bills to find the actual kWh consumption for your home or business. Find the average per day and the peak daily kWh consumption. We have solar battery packs available that provide power storage from 1kWh to more than 100 kWh.

What is a Kilo-Watt Hour?

A kilo-watt hour is a measure of 1,000 watts during one hour. The abbreviation for kilo-watt hour is kWh. So 1,000 watts during one hour is 1 kWh. The power company measures energy in kWh in order to calculate your monthly bill. 5kwh is basic for a small home. 5 kwh battery bank is scalable for 10kwh, 15kwh, 20kwh or even more.

How Many kwh Do You Need for your house?

The average home uses 900 kWh per month, or 10,800 per year, according to the U.S. Energy Information Agency EIA. That means the average power required per day is 30 kWh. Now, when sizing a grid-tied solar battery system for daily usage, you will want a system that can deliver up to 30 kWh, or possibly more for peak usage days. However, if you also want the system to provide off-grid backup battery storage, then you will typically choose 3X to 5X the daily average, or 90 to 150 kWh. This should provide ample storage for complete system autonomy in case of an extended power outage of 3 to 5 days. Combine the battery storage with a PV solar panel system to ensure that you will have a renewable power source to keep the batteries charged.
