Battery Powered Solar Dream

Its common knowledge to reap the most benefit from one’s investment. Solar system without batteries is beneficial at day time but we cannot reap its benefits at night. To enhance its capabilities we can add battery storage. Addition of batteries will

Store excess solar energy generated during the day for use at night, increasing self-reliance and grid independence.
Even benefit during day time by allowing users to utilize stored energy during peak pricing periods thus lowering electricity bills.
Even benefit during day time by allowing users to utilize stored energy during peak pricing periods thus lowering electricity bills.
Economic analyses indicate that the payback period for solar systems with battery storage can be reduced from 13 years to 11.7 years when considering peak demand pricing

What is a Solar Battery?

A battery is a device which converts electrical energy into chemical energy and vice versa. It is like a tiny chemical factory where electrons are produced and pushed through a wire to power something like a light bulb; think of it like a “chemical fuel” that can be used to create electricity on demand, with the positive and negative terminals acting as the “outlet” to access that power.

How Does a Battery Work?

Just like a rubber band if one stretches it energy is stored in it. This stored energy can be released back one string is released similarly a battery works by storing chemical energy inside itself, and when you connect it to a device, it releases that energy as electricity through a chemical reaction.

Maximize solar generation and utilization effeciency.

Why Invest in Battery

Battery backup can be an incremental upgrade tp ypur existing solar system because:

Electricity tariff is forecasted to increase by 56% in next two years.
Gap between feed in tariff and electricity tariff is too large to reap benefits from feed in tariff. (Feed in Tariff: 5 cents vs Grid Tariff: 33 Cents on peak)
Global warming and sudden weather changes have increased chances of natural disasters and it is imperative to build capacity to face these challenges.
