in short, On average a 40-watt solar panel will produce 160-200 watt-hours of power in a full day. 40w solar panels are designed to produce 40 watts of power per hour under standard test conditions (STC) which include radiation of 1 kW/m2, a cell temperature of 25°C, and no wind. .
By knowing how much power can a 40w solar panel produce will let you know the actual worth of your solar panel and also this will determine what you can run on your. .
To calculate the value of amps or current use this formula (Amps = Watt/Volts) Under ideal sunlight conditions, a 12v 40W solar panel will produce 18 volts, 2.2 amps, and 40-watt voltage output will depend on the intensity of the sun so which means it will fluctuate a lot so does the current. .
So you'll need a charge controller or regulator to manage the flow of voltage so you can charge your 12v battery. To calculate the size of the charge controller or regulator for your solar panel use this formula you'll need a 5A charge controller with a 40W solar panelbut I would recommend a 10A charge controller which will give you a room.

Here are some charts on what size solar panel you need to charge 12v and 24v 200ah lead acid or lithium (LiFePO4) battery. .
The maximum charging current for a 200Ah lithium battery is usually 100A and the ideal charging current for a lead-acid or AGM battery is. To charge a 200Ah battery (2,400Wh), use a solar panel with at least 600 watts. This is based on 4 hours of daily sunlight (2,400Wh ÷ 4 hours = 600W). Remember to account for efficiency losses; a less efficient panel will need more wattage to reach the same charging goal. [pdf]

To recharge your battery from time to time you would need the right size solar panel to do the job! Read the below article to find out the suitable solar panel size for your battery bank .
Note!The battery size will be based on running your inverter at its full capacity Assumptions 1. Modified sine wave inverter efficiency: 85% 2. Pure sine wave inverter efficiency:90% 3. Lithium Battery:100% Depth of discharge limit 4. lead-acid. .
To calculate the battery capacity for your inverter use this formula Inverter capacity (W)*Runtime (hrs)/solar system voltage = Battery Size*1.15 Multiply the result by 2 for lead-acid type. .
You would need around 24v150Ah Lithium or 24v 300Ah Lead-acid Batteryto run a 3000-watt inverter for 1 hour at its full capacity .
Here's a battery size chart for any size inverter with 1 hour of load runtime Note! The input voltage of the inverter should match the battery voltage. (For example 12v battery for 12v. A 2-3kW inverter is pretty standard for a 24V system. Just keep in mind that you don't want to pull over 100A from your battery if you can avoid it, as that can lead to higher costs for wiring and equipment. [pdf]
