Trina and Yingli are among the top 5 Chinese Solar Manufacturers, Canadian Solar is no where in the top ten list. If not Trina then instead of Canadian Solar, I would rather go with Sharp which costs about Rs.110 per watt.
I have been planning for a 3KW solar setup and measuring power consumption of electrical appliances to see how much load to put on solar.
I have a Dawlance fridge that I want to put on solar, but I am concerned about the start-up load of the fridge. Upon compressor start-up it uses 7.1 amps for a second and the running amps are 1.24. Is there a way to reduce the start-up current? I was told it can be done by replacing the fridge's capacitor with one that has a higher microfarad rating. It will help reduce the momentary spike in current. Is it possible to do this just by replacing the capacitor?
I was also measuring the start-up current of my 1 ton Mitsubishi split. Surprisingly, it started at about 2.9 amps, and then in a few seconds it was at 5.5amps. From what I know most solar installers say you need an inverter based AC if you want to run it on solar, because non-inverter ACs have a high start-up current. But it seems like my non-inverter AC can run on solar. If my ACs start-up current is low, can I run it safely on solar power?
If you do go for Sharp, make sure they are Japanese made e.g this model seems to be japanese made http://solaergy.com/shop/pvmodules/sharp-nu200-ab/
There is a video on youtube, where a guy is using a small fridge for than 9 days with 500W Solar panels and Morningstar's prostar 30. here is a link to his 290W video, watch the one in which he has installed 500W panels
Will it be a Grid tied system or a Grid interactive or Off grid system ? For the off-grid use you will need a large battery bank preferably at 48V or even higher voltage.
