What is solar air conditioner advantage?
off grid dc inverter solar air conditioner can be driven by 100% on solar power run on DC power. solar battery power solar air conditioner doesn't require power from the utility company. An example of this type are solar-powered wall-mounted air-conditioning units. They operate on Solar DC power only, and use external battery backup (Normally for 8-10 hours battery power is economical), so that the unit will continue to function even when the sun is not shining, like at night. A wall-mounted unit is expensive – $700-1000 – but since it operates totally “off-grid” which means there are no energy costs during operation.
The new generation 100% solar DC AC adopts perfect inverter controller technology. In sunshine day, the solar panel produce the DC48V Power to charge the battery to storage the power at the same provide the power to DC48V compressor and fan motor, then will cooling or heating the room.
The indoor motor, compressor, outdoor motor in the new generation 100% solar air conditioner system all adopt brushless DC motor.It greatly improved the stability and efficiency of system.
①9000 / 12,000 / 24,000 BTU Capacity with or without a heat pump;
②Direct PV 48V powered, no conversion process.(off grid);
③Easy installation, very similar like the traditional AC;
④No limited by power supply and climate, apply for world wild use.(Suitable for T3 tropical area)
⑤Full DC 3D Control( adopt world well know DC compressor, DC indoor fan motor, DC outdoor Fan motor), reliable running and high efficiency.
Cost of solar AC and Conventional AC– an overview of cost-effectiveness
As regards to the price, conventional air conditioning system is surely damn cheap and affordable in terms of one-time investment but for a longer period of usage, it becomes costlier than Solar AC.
For example, if you buy a regular 1 ton AC , the price is about of USD$ 200 – USD$ 300 and will connect with the electric power and will start enjoying cooling.
Contrary to this, solar ac unit cost is a bit expensive and will demand you to make a sizable amount of investments, especially for off-grid unit. The Solar AC Unit + Batteries + Solar Panels + Solar controller around 1950 USD$ - at a time, but it will pay you off during 3-4 years and you can start enjoying cooling system completely free of cost later on. For acdc hybrid solar inverter air conditioner, the AC Unit + Solar panel about 950USD$, it will pay you off during 1 years.
Let us say if 1 TR AC consumes 2 unit of electricity for USD$ 0.11 per unit, the calculation can be as below;
USD$. 0.22per hour ( USD$.0.11*2)
USD$ 3.23/- per day if used for 15 hours on an average a day ( USD$.0.22*15).
USD$. 96.84/- per month ( 3.23*30)
USD$. 774/- for 8 months in a year ( USD$ 96.84*8) if 4 months excluded for winter.
USD$. 2324/- in 3 years excluding 12 months for winter of 3 years ( USD$. 774.68*3)
In a span of 3 years, the one time investments seem to be coming back and no further expenses required although expenses for payment of electric bills even after 3 years in case of using conventional AC will continue.
If a person uses solar AC for 6 years and another person uses conventional AC for 6 years, USD$ 2800 can be saved in case, solar AC is used.
