If you wish to put money into renewable vitality, then understanding how a photo voltaic battery system works is essential.

A photo voltaic system will assist your property harness green energy, plus you’ll be able to retailer electrical energy generated for later use.

Below now we have compiled a step-by-step information on the workings of a photo voltaic battery.

How a Solar Battery Works

Step 1: Solar Panels and Solar Power

The course of begins with a photo voltaic panel system in an space uncovered to the solar, largely positioned on the roof. When daylight hits the photo voltaic panels, seen mild is transformed into {an electrical} present.

The Direct Current (DC) electrical energy technology of the system will be transformed to Alternating Current (AC) or stored as DC present – relying on the kind of battery storage you employ.

Step 2: Supplying Electricity and Charging the Solar Batteries

Your house’s electrical system will take first precedence for the ability generated by the photo voltaic panels. Electricity produced by the panels will feed instantly into the home’s electrical panel.

This will present electrical energy for lights and home equipment.

Often instances a photo voltaic system will produce extra electrical energy, particularly on summer time days when no heating is required and the solar is out.

Without a photo voltaic vitality storage system, this unused electrical energy will circulate again into {the electrical} grid via web metering.

However, owners can set up house vitality storage methods to seize and retailer the electrical energy produced by the panels.

Solar vitality will circulate into the battery and cost it. The pace that the battery fees will rely on the quantity of additional electrical energy being produced, in addition to the present electrical energy use of the house.

Step 3: AC and DC Charging

Homes run on AC, whereas most batteries (like our laptops) require DC for charging – nevertheless you do get AC batteries.

An AC battery can settle for AC energy and converts the ability to DC utilizing an inverter. The battery is then charged this manner.

When the battery storage is used to energy the house, the inverter re-converts the vitality again to AC energy.

Most photo voltaic vitality methods use AC batteries. AC batteries are appropriate with many forms of photo voltaic methods and will be paired with any inverter that may settle for AC output.

These batteries are very simple to put in into an current photo voltaic PV system.

DC batteries wouldn’t have built-in inverters and should be charged by DC energy. These batteries require a particular inverter that instantly feeds the DC energy produced by the photo voltaic powers into the battery.

To energy the house, these batteries require an exterior inverter to transform the ability into AC energy.

DC photo voltaic batteries are far more energy-efficient than AC batteries, as every time present is transformed via an inverter, roughly 5% is misplaced as warmth.

A DC photo voltaic battery price lower than an AC battery.

Step 4: Discharging the vitality storage

Once the battery is charged, it’ll retailer energy till there may be an electrical energy demand for the house.

If there’s a disruption within the energy grid, the batteries will mechanically activate and supply energy to the circuits they’re related to.

Homeowners can even select to manually discharge their photo voltaic battery storage.

Types of Solar Batteries

There are 4 forms of photo voltaic batteries:

  • Lithium-Ion batteries can deal with excessive vitality, cost quick, however are nonetheless comparatively costly.
  • Lead Acid batteries are probably the most reasonably priced batteries. They take a very long time to recharge and require frequent upkeep.
  • Nickle Based batteries are a superb selection as they recharge pretty fast, require little upkeep, and might stand up to temperature extremes.
  • Flow batteries are giant and costly. They use an electrolyte liquid to retailer electrical energy. 


Solar battery methods are usually not difficult, and all of it begins once you set up photo voltaic panels.

These battery methods generate electrical energy utilizing a renewable useful resource – the solar – and might present your property with electrical energy even when there is no such thing as a energy on the grid.
