How Much Power Does a 800W Solar Panel Produce?

The average 800-watt solar panel will produce between 230 and 256 amp hours per day. This can vary depending on the quality of the panel, the amount of sunlight it receives, and the efficiency of the solar cells.

The average home uses about 30 amp hours per day, so a system this size would be able to power most homes completely. Solar panels are a great way to reduce your reliance on the grid and lower your carbon footprint.

What Size Charge Controller Do I Need for 800 Watts of Solar?

As the use of solar energy becomes more prevalent, those considering solar panel installation may find themselves wondering what components they need.

One important component is the controller, which regulates the flow of electricity from the solar panel to the battery.

The size of the controller needed depends on the number of panels and how they are wired.

A 60-100A controller is typically required for an 800-watt solar panel setup, depending on the number of panels and how they’re wired.

This guide will help you select the right size controller for your needs.

How Do I Choose the Right Size Solar Charge Controller for 800W Solar System?

As the popularity of solar energy systems increases, so does the number of solar charge controllers on the market.

Solar power is a great way to save on your energy bill, and with the right solar charge controller, you can maximize your savings.

With so many options available, it can be difficult to know which one is right for your 800w solar system. But how do you choose the right size solar charge controller for your 800w solar system?

Here Are a Few Things to Consider when Choosing a Solar Charge Controller for Your System:

  • The first is the size of the solar panel array. The solar charge controller must be able to handle the maximum output of the solar panel array.
  • Also, the type of controller that you need. There are two main types of controllers; MPPT and PWM.
  • Follow by the type of batteries you are using. Lead-acid batteries are the most common, but if you are using lithium-ion batteries, you will need a different solar charge controller.
  • Finally, you need to consider the features you want in a solar charge controller. Do you want a simple on/off switch, or do you want a controller with a display that shows you the status of the charge?

How Many Batteries to Run 800 Watts Solar System?

In order to run an 800-watt solar system, you will need at least 4 batteries. This will allow you to store enough energy to power your system when the sun is not shining.

You may need more batteries if you live in an area with long periods of cloudy weather.

First, the battery bank capacity is 200Ah at 24V and 400Ah at 12V. This allows for a maximum charge/discharge rate of 8C/16C.

We can use the batteries in a wide variety of applications, including renewable energy storage, backup power, and grid-tied systems.

By calculation;

Our battery capacity (Ah) = Average daily energy production (Ah) ÷ (battery bank voltage x battery depth of discharge).

Meaning if you can run 2 pcs of 200 Ah AGM or GEL batteries connected in parallel, you will get 12V or 3 pcs of 100 Ah Lithium batteries, you still have a 12V battery bank.

However, for a 24V battery system, you can use 4 pcs of 200 Ah AGM or GEL batteries, meaning you have to connect 2 strings of the two batteries in parallel. Or, still, you can run 4 pcs of 100 Ah Lithium batteries and connect the 2 strings of the two batteries in parallel.

The main advantage of using Lithium batteries is that they have a higher energy density than AGM or GEL batteries. This means that for size and weight, a Lithium battery will have a higher capacity than an AGM or GEL battery.

What Size of Inverter to Use with A 800 Watt Solar System?

When determining what size of an inverter to use with an 800-watt solar system, it is important to consider the specific needs of your home or business.

The size of the inverter will determine the amount of power that can be generated, and the 800-watt system is capable of generating a meaningful amount of power.

An 800-watt solar system will require a minimum of a 1,000 to 1,600-watt inverter. However, it is recommended to use a 3,000-watt inverter for a system of this size to ensure that you have enough power to run appliances and electronics.


In conclusion, an 800-watt system generally will produce between 3 to 4 kWh of energy daily. This can offset a significant portion of your monthly energy costs and help you become more energy independent. With solar power, you can produce your own electricity, and help reduce your carbon footprint.

We can store the generated energy using 4 pcs of 200 Ah AGM or GEL batteries, or 4 pcs of 100 Ah Lithium batteries on a 24V battery system. This will ensure that the energy is available when needed and can be used to power appliances or devices.

And lastly, the charge controller is one of the most important components in a solar power system. It regulates the flow of electricity from the solar panels to the batteries and prevents the batteries from being overcharged.

A higher current-rated charge controller can be used if you plan to increase the size of the solar system. This will allow you to safely increase the amount of electricity that flows into the batteries and prevent damage to the system.
