Choosing the right size depends on the level of energy independence that a renewable energy owner wants. It may simply boil down to what you can afford. These levels range from 100 percent or completely off the grid (the most costly), to a simple energy backup for emergencies.

100% energy independence or completely off the grid: this requires a huge investment in terms of generation and storage. In addition, it may require other power sources such as fossil fuels or wind generators.

High energy independence: This requires a solar system with enough batteries to last a few days or even through the winter. PV systems are sized to enable the owner to have surplus energy to store during summer and be self-sufficient through winter without relying too much on the grid. The customer will still rely on the grid for backup just in case there are prolonged days of bad weather.

Summertime independence: Customer installs just enough panels and storage capacity to get through a normal summer day but will have to draw power from the grid during the winter.

Peak time independence: Battery size should be large enough to supply power during peak times when electricity rates are highest.

Reduced reliance on the grid during peak times: Some customers cannot afford to install enough storage to cover their entire peak time usage. In such a case, some will install a system that will enable them to at least reduce part of their grid usage during these times.

Emergency power backup: This requires smaller energy storage, enough to cover a short power outage. Some customers use this together with fuel generators. Battery storage is only required for the short duration from the time grid power goes out, to when the alternative power becomes available.

Even though a solar energy system is a great investment that reduces your electricity bills, it is not possible to completely get off the grid without investing in large storage systems. However, adding modest battery storage to a grid connected to solar systems is a better way of increasing your independence from the grid without spending too much.

Most marketers have online tools that can help you get the right size battery based on various factors. However, it is advisable to consult professionals for the best advice.

Customers with solar systems are increasingly adding battery storage to reduce their electricity costs or become independent from the grid. With better technology and prices getting lower every day, battery storage is becoming an appealing component to many solar power system owners.

This type of storage allows the customer to charge their batteries during the day and then discharge them when there is no generation. This permits homeowners and businesses to have a backup power source and save on electricity bills. In addition, you can sail through cloudy periods or other times when power generation is low.

The National Safety Council Electrical Safety Facts & Tips can help minimize electrical hazards and cut down the risk of accidents through education.

Electricity is nature’s most versatile form of energy.  The power of electricity can be dangerous if it is not used correctly. Electrical energy can damage property and ignite fires. It is important to ensure your safety around “Hot” electricity. The hazard of electricity cannot be eliminated, but it can be controlled. The more you understand about electrical energy, the safer you will be at work and home:

What causes electric shock?You can get an electric shock if you touch a grounded surface and hazardous electrical equipment at the same time. The shock happens when the flow of electric current (amperage) from the electrical equipment goes through your body to the ground.  Just a small amount of amperage can hurt or be fatal.
