The increasing demand for energy has prompted several research groups to evaluate different renewable energy resources as a whole or as a share. Undoubtedly, solar energy is one of the cheapest and easiest way to generate electricity to mitigate the energy crisis. However, generating electricity from solar energy is not continuous but an addition of an energy storage system changes the system dynamics.
In renewable energy systems, standalone solar photovoltaic (PV) power systems are doing great, but a hybrid system (Solar PV + Battery) are more capable of providing uninterruptible power. An adequate storage option coupled with solar PV system resulted not only in an uninterrupted supply, but also resulted into reduce level of CO2 emission. Furthermore resulting into net savings as well.
A study by EUPD Research shows that a residential solar PV system coupled with a battery storage system enables a CO2 reduction of up to 85% compared to purchasing from the grid alone. Without storage, however, only a 45% reduction can be achieved.
Conclusion of the study can be understood with the help of the example below:
A private household with a common heat pump and an electric vehicle is confronted with around 10,000 kWh of annual electricity consumption. To meet enhance consumption and significantly reduce CO2 emissions in the future, the conventional 7.5 kWp solar system* is hardly sufficient. While the system with 10 kWp solar power equipped with 12 kWh storage able to save up to 59% of the CO2 compared to the purchase of electricity from grid generating electricity from non-renewable sources. A standalone solar PV system without storage can achieve just less than half of it i.e., only 28%. However, with a 15-kWp PV system and a 15-kWh battery storage, CO2 savings of 68% can be achieved by private household.
The electrification of heat generation and electromobility are significantly increasing electricity consumption in private households. With your own photovoltaic system, you can cover a large part of the electricity demand. Addition of an energy storage system would be icing on the cake.
Don’t wait! Solar has never been so affordable with up to 50% off the cost. Call Staten Solar for your hybrid (Solar+Storage) system for your household or for your business.
