Web Connected - PWM Solar Charger

I have already build a PWM solar controller, mainly with P-MOSFET  and arduino-nano. And N-MOSFET to switch on some lights when night falls.

Following a few snaps of it. It uses 10W /12V solar panel with 7Ah 12V Lead Acid battery.

Following is a realtime battery voltage using ESP8266 and  thingspeak platform.

Got a New 80W solar panel for Rs.9000. Plan is to build PWM Solar charger with Web interface so i can see the statistics of the Solar Charger System, Battery Condition via Internet and within Wi-Fi.

Following the Plan for new PWM solar charger (Web Enabled).

A Sample sketch for the webpage. Running on ESP8266 in Access Point Mode.
