[Abstract]

With the popularity and development of solar energy, solar air conditioners can not only save money, but also save energy and protect the environment. They are especially popular. In particular, 100% solar air conditioners are suitable for areas with unstable voltage, no electricity, and areas with relatively high electricity bills. One-time investment can bring long-term benefits.


The following is a design example of 100% solar air conditioners for reference.

[Main body]

1. Basic requirements:

An Allen from Botswana works in a local suburb and lives in two 20㎡ bedrooms and a 30㎡ living room. The voltage is not stable, but the weather is hot in summer and requires air conditioning, so the configuration is required His case of solar air conditioning programs.


2. Design ideas:

Applicable installation area according to 100% solar air conditioner:

12000btu 100% solar air conditioner: 12 ~ 22㎡

18000btu 100% solar air conditioner: 20 ~ 35㎡

 

So, according to Allen's living conditions, there are the following configurations:

2pcs 20㎡ bedroom, equipped with 2 sets of 12000btu100% solar air conditioner;

1PC 30㎡ living room, equipped with a set of 18000btu 100% solar air conditioner.

100% solar air conditioner design

Product List:

12000btu 100% solar air conditioner:

12000btu DC 48V 100% Solar Air Conditioner * 2sets

4pcs 340W solar panels * 2sets

4pcs 125AH GEL solar battery * 2sets

Solar charge controller * 2sets

And other accessories.

 

18000btu 100% solar air conditioner:

18000btu DC 48V 100% Solar Air Conditioner

4pcs 350W solar panels

4pcs 150AH GEL solar battery

Solar charge controller

And other accessories.

 

3. Design Features:

In a 100% solar air-conditioning system, solar panels convert light energy into electricity and provide a DC voltage of 48V for the air-conditioning system to operate.


When the air conditioner is used under light conditions, the electricity generated by the solar panels will be directly used for the operation of the air conditioning system. Excess power will be stored in the battery.


If the air conditioner is not used under light conditions, the electricity generated by the solar panel will be stored in the battery for use when the air conditioner is running.

 

1 set 12000btu 100% solar air conditioner. The electricity generated by the solar panel every day is enough to provide the air conditioner to run for 8 hours. The excess power will be stored in the battery. When the battery is fully stored, it can be used for 8 hours when the air conditioner is running.

 

1 set 18000btu 100% solar air conditioner. The electricity generated by the solar panel every day is enough to provide the air conditioner to run for 5.6 hours. The excess power will be stored in the battery. When the battery is fully stored, it can be used for 6.3 hours when the air conditioner is running.

 

Considering the area of Allen's two bedrooms and living room, the 2 sets of 12000btu 100% solar air conditioner and 1set 18000btu 100% solar air conditioner are configured.

 

4.  Allen is very satisfied with the design of this scheme, but there are still some doubts about 100% solar air conditioners:

 

① Can the running time of the air conditioner be longer? For example, run for ten hours a day.

Yes, we can adjust and reconfigure the number of solar panels and batteries according to the working hours or time periods you require.

 

② Can it use 2pcs indoor units and 1pc outdoor unit for the solar air conditioner?

We do not recommend using this type of air conditioner, it will reduce the startup speed of the air conditioner, affect the air conditioner performance and operating effect, and consume more power.

 

③ Can it still be used in the event of a power outage or rainy day?

Yes, as long as there is electricity stored in the battery, the air conditioner can still be used as usual, even if there is a power outage or a rainy day.

[Conclusion]

100% solar air-conditioning is not only energy-saving but also safe and pollution-free, which saves expenses and produces good economic benefits for many families. It is suitable for areas with unstable voltage, no electricity, and relatively expensive electricity. This 100% solar air conditioning solution is suitable for most homes, but it still needs to be designed according to actual conditions. There are many design factors, and the seasonal distribution of sunlight in different regions is uneven. The specific configuration scheme product details need to be configured according to the situation of different families to avoid unnecessary waste.
