Why this Blog?

The purpose of creation of this new blog was to add all my work that will solely related to my DIY Solar and wind electricity generation system. I will also add here the adventure of my DIY micro-hydro turbine (PAT) unit that has been planned to be implemented in the beautiful Kalam valley. In the recent past i unintentionally got attraction toward the green energy and studied a lot about.

My last visit to Karachi home was the turning point to divert all my intentions and resources toward getting into hybrid solar+wind electricity system. The 12 hours shedding at Karachi was really a mental shock to me. The 2Hours alternate load shedding scheme was so pathetic that for three nights i had only 6 hours of sleep in total. The Starting/Stopping the generator (located at the third floor) was a real muscular exercise especially the last part of the night.

The ready made solution requires a handsome amount of money. Here i will post my DIY approach to get the job done considering the advantage of being low cost, worth of experience and as per my requirement and quality. I intend to work on both Solar and wind turbine simultaneously so that to give the relief to my family.

Lets see will i have success in this endeavor?

MPPT from Hong Kong to Pakistan in 8 Days.

I have ordered the following MPPT from a Chinese supplier through the website Aliexpress (http://www.aliexpress.com).

China (Mainland) (Zhejiang)

45A Tracer 4215RN EP MPPT Solar Controller with MT-5 Remote Meter, FREE SHIPPING BY DHL

This MPPT cost me around 289 US dollar+ custom duty.The ordering date was 01-June-2012 and as can be seen in the order tracking it just touched down Lahore today on 8th June, 2012. Wow pretty fast delivery...

Maximum PV input power of this MPPT  is 24V /1170W. My current solar panels can generate 540W, However, I have ordered this MPPT because in future i want to double the quantity of solar panels (1080W) so no need of purchasing the new MPPT.
