There are three vital reasons that people invest in solar energy systems: solar power is environmentally friendly, a great way to become less reliant on the national grid, and it can actually make you money. With energy costs liable to the influence of external factors, this means they can fluctuate and rise often. 

Instead, if you are reliant on your own home battery storage system, you do not need to depend on the national grid. This means you are more self-sufficient and financially secure, especially if you only use your stored solar energy during peak hours when traditional electricity is more expensive.
