Compatibility with Inverter


Like the battery, solar panel should also be compatible with the rating of the inverter. For example, a 12V solar panel should be paired with a 12V inverter and a 24V solar panel should be used with a 24V inverter. Inverters are available in different ratings like 12V, 24V, 48V, etc.

Application

A 12V solar panel can be used for different applications like street lights, tourist van, shops, small homes, home lighting, mobile charging, solar bag, science project, solar water pump, office, fishing boats, etc.

 

A 24V solar panel can be used in big homes, hospitals, banks, offices, on grid applications like factories, apartments, parking, parks, government building, solar parks, etc. To see our case studies.

 

Range Pricing

12V solar panel is available in 10W, 20W, 40W, 50W, 125W, 160W and 180W, whereas 24V is available in 330W and 350W.

 

Price of a 12V solar panel can vary in between Rs. 2,400 and Rs. 15,000. Price of a 24V solar panel can vary in between Rs. 11,000 and Rs. 24,000.

 

Solar Panel Buying Guide

Customers are often confused as to how much load can be supported by solar panels. One important point to highlight here is that the function of a solar panel is to charge the battery and not to make appliances work. Let’s talk more about this in detail.

 

Must read this example, a small home needs a minimum of 300 W to run a fridge, fan, and light which can be easily supported by a 1 kVa inverter. Let’s calculate and see what is the load of the house in use in case of a Power failure. Now, the time for which appliances will work on back up depends on the battery’s capacity. Typically a 150Ah battery with 12V rating can store upto 1800 W of power.

 

Simple Calculation is 150 AH battery * 12V = 1800 W

 

Taking a lead acid battery with 70% efficiency only 1400 W load should be available and will work for 4-5 hours. Considering a small home needs a minimum of 300 W.

 

This blog is dedicated for readers to decide as to how many solar panels they should buy to support the normal functioning of their house, in case of a power cut, what voltage of solar panel - 12V or 24V is suitable for you, and for how many hours my fan and lights will work on solar in case of a load shedding. A lot of this depends upon the ratings of the battery, inverter and charge controller. We hope we were able to help you to some extent. You can keep writing to us for more such queries in comment section.

 

Do Solar Panels Work At Night?

Normal solar panels don’t work at night. But scientists at Stanford University have figured out a way to use an experimental solar panel’s radiative cooling to generate a small amount of electricity at night. It might be enough to run an LED light bulb or partially charge a cell phone. Further studies are being conducted to see if there are broader applications.
