Solar Project

A solar PV installation has been a dream from the start of this farm project but HIGH cost and lack of funds has always forced us to just grit our teeth an pay the electric bill. a couple of months ago I came across an offer to sell used panels in bulk an a very low price. These were removed from a 10 year old PV power plant that was being upgraded to increase it’s production and take advantage of tax law changes. This model of Sanyo panels are guaranteed to produce 90% after 10 years and 80% after 20 years. It appears to me that there may be a lot of used Solar equipment that will be available soon.

To do a simple system, gridtie, was selected to get the most bang for the buck in reducing the Utility costs that are scheduled to increase even more from their present high rate.

         The Enphase Energy Microinverter System solves solar power challenges by performing Maximum Power Point Tracking (MPPT) at each solar module. MPPT is an algorithm used to calculate and respond to temperature and light changes detected on a solar power system, and to determine how much power to draw from the module.
The SANYO HIT-HIP (Heterojunction with Intrinsic Thin Layer) solar panel is made of a thin single crystalline silicon cells surrounded by ultra-thin amorphous silicon layers.  The unique structure produces highly efficient cells capable of achieving more than 18% module efficiency while producing more power even at higher temperatures

These panels leads are terminated in MC connectors for a massive series- parallel DC grid so I needed to convert them to MC-4 connectors that would match the micro controllers input leads.
These controllers are becoming available in bulk, as well. They are too small for more modern higher output panels of commercial system upgrades.
