Solar Battery Storage Calculator – Characteristics and Storage
The solar battery storage is a device that stores up energy for later use and is charged using a solar system; the stored energy is used during electric power outage or high energy demand. A solar storage is important as it stores trapped sunlight during the day to be used as energy when there is no sun, i.e. at night or during cold seasons. Those who do not have adequate solar storage facilities will be forced to feed excess power straight to the grid, which they would later buy at a higher rate. The solar battery is mostly used in residential and commercial buildings. Solar batteries are chosen based on certain factors such as: how much power it can provide and how long it would last. The capacity and power of a solar battery is important depending on the facility you want the solar battery to run; the capacity of the battery tells you the amount of energy in kilowatt hours, kwh, your battery can store while its power rating in kw, gives you the picture of how much energy can be provided. In most cases, people use multiple battery storage batteries to get maximum energy. Another important factor to be considered in selecting a battery storage type is the rate of discharge; you certainly do not want a battery that would dissipate energy faster than it should, the retaining capacity of the battery is key. This also boils down to efficiency, a solar battery with high efficiency will serve you much longer. The battery life represents the number of cycles a battery can go, as much as the depletion of a battery’s performance is inevitable, you still want to use one with a high life cycle to serve for a long period.

What are the characteristics of solar battery?
Solar batteries generate power from the sun and converts it into useful electric energy; these batteries have the general properties of a battery as well as its unique characteristics, these characteristics define the maximum power derived from a solar battery, here are a few:
- Short circuit current, Isc – this represents the current flowing through a solar battery when the voltage across it is zero. It is also the largest current a solar cell can provide, and it is dependent on the area of the solar cell, the number of photons, optical properties, spectrum of incident light and collection probability of the cell
- Open circuit voltage, Voc – this is the PD, potential difference across two disconnected terminals of a solar battery, i.e. it is the amount of voltage needed to stop current flow in a solar battery. The open circuit voltage is also referred to as the electromotive force of a solar battery and is dependent on factors like illumination, charge and temperature.
- Fill factor, FF – the fill factor of a solar cell is a measure of the quality of a solar cell.
- Efficiency, η – this is a measure of the amount of useful electrical energy produced by a solar battery compared to the solar energy gotten. Remember, solar cells convert solar energy to electrical energy, therefore the amount of electrical energy for use gotten from the conversion process at standard conditions is the efficiency of the solar battery. The efficiency of a solar battery is mostly affected by band gap energy, which is the minimum energy needed to remove a photon from the sun.
- How do you store a solar battery properly?
- Cold can be a hazard to solar batteries; most are designed to function at 77oF, with a minimum operating temperature of 50 oF and a maximum of 85 oF, at extreme temperatures below or above the standard, batteries decrease in their functionality. Heat is also referred to as an enemy of batteries, as they destroy batteries faster. Solar batteries are best kept in properly insulated environment away from direct sunlight (heat) and with sufficient room to absorb or store heat. If batteries are to be installed outside a building or underground, it is necessary to avoid a location with direct sunlight. The use of sensors on batteries to indicate a deviation from the normal temperature as well as charge controllers to adjust voltage of solar cells to a 100% charge state based on temperature is also a safe way of storing these batteries. For commercial solar batteries, a commercial grade battery enclosure is a more secure way of protecting the solar batteries.
