More efficient models of solar panel are being held back from release by firms struggling to cope as price of existing stocks continue to plummet. P-type technologies are the most mainstream solar product being sold on the market, but competitive pricing and manufacturing has meant that the industry cannot afford to invest in research for new, more effective N-type technology.

This page will show the step-by-step instructions for assembling the circuitry associated with current monitoring. Current monitoring is controled by IC1 (on the schematic), with supporting hardware. The ability to monitor its own current draw is what allows the maximum power point tracking (MPPT) algorithm to adapt and adjust as the peak efficiency point changes. […]
This post assumes that you have already tested the power circuitry to verify the unit draws about 100 mA (1000 milli-Amps = 1 amp) or less (see the picture below). The Aruino should draw about 60 mA and the shield circuitry should draw about 30 mA when unloaded, but active. That’s how I’m getting 90 […]
