The real deal
Log from Open source Solar system
So after some research i decided on 2* 300w 24v solar panels. I also bought a Mppt solar charger from Victron energy. There is a lot of other version and prices, but this was the best and cheapest that fit my specs that i wanted with my budget.

PV Peltier Water Collector
Hacker page by David Scholten
Using 45 Watts of PV power (~18V MPP), two 30W Peltiers (0-9V), anMPPT buck converter (IV-matching) and a temperature switch (anti-frost),water is slowly collected at the cold-side heat sink where it falls througha funnel and into a bottle.

DIY Little.Big MPPT Solar charger
Details from DIY Little.Big MPPT Solar charger
By using MPPT technology, solar power systems can operate at peak efficiency, maximizing the energy harvest from the solar panels and improving the overall performance of solar energy systems. Different MPPT algorithms and techniques can be employed,...

Instructions from ARDUINO MPPT SOLAR CHARGE CONTROLLER
This project is consists of 40 steps.So for simplicity I divided the entire project in to small sections.Click on the link which you want to see.1. Basics on MPPT charge controller2. Buck circuit working and design calculation3. Testing the Buck Circuit4....

Solar harvesting into Li-ion battery
Details from Solar harvesting into Li-ion battery
I designed it because I took part in the HackadayPrize2018 Power Harvesting challenge with a 1x1 inch Tiny Solar Energy Module and found a lot of interest in selling it. However since most projects have different power demands and people want...

Experiments in Off The Grid Solar
Details from Experiments in Off The Grid Solar
Going to be a very simple setup, most likely two of my three panels, and MPPT charge controller and a nice deep cycle lead acid battery. The system only needs to run a few hundred watts of 12V DC hardware (lights and water pumps) so a simple charge controller...

Solar panel maximum power point setting
Instructions from Solar UPS Power Supply
The MPPT charger settings as follows:Connecting laboratory power unit to DCINSetting laboratory power unit to solar panel "voltage at max power"Measuring JP1 voltageSetting POT1 while JP1 voltage will be 2,75VDefault settings: 17.0-17.5V solar panel...

Open MPPT
Details from Open MPPT
The MPPT design is based on the IC by TI, this is mostly to serve as either a nice generic unit for people to use, or as an open source reference design.I'm no expert is designing these things, however I feel like the design is OK :)The design is made...

Misunderstandings - 2
Log from The AEMLIC Solar Harvesting board - My Journey
TO DOThis will be about selecting the right solar cell.I assumed I could use the 6 or 7 volt solar cell that I already had, as long as the light was only bright enough to provide an actual voltage of only 2V or 3V. It seems that this assumption is incorrect....

Trying the PowMr
Log from Airwave Inspector
I found out the hard way that the PowMr was not putting out a small regulated DC voltage like most MPPT controllers claim to, and the output was in fact the whole 25V of the battery pack.The cable for the screen for it is also wayyyy to short to make...

Solar Boat Controller
Details from Solar Boat Controller
GoalsInputSeamlessly charge the LiFePO4 battery from both solar panels with MPPT and dockside charger.The battery came with a 120V charger so the transistion stage could look something like...Detect dockside powerDisable MPPT chargerRelay to connect...

Choosing the right resistors
Log from Flexible wearable power harvester
The BQ25504 have the ability to provide undervoltage and overvoltage charging regulation, which ensures that the storage component doesn't get damaged. For programming this threshold certain resistor values are required. There's a formula on the datasheet,...

Micro generator platform for water and wind energy
Details from Micro generator platform for water and wind energy
Controller is being designed with three specific operating topologies in mind. Current state: We have a working software for the 1.) and 3.) topology. Next, custom HW design and software support for 2.) topology is planned. 1.) Generator is connected...

Home Made Arduino Based MPPT Charge Controller
Details from Home Made Arduino Based MPPT Charge Controller
How MPPT works? Why 150W solar panel does not equal to 150 w?For example, you bought a new solar panel from the market which can deliver 7 amps current, under charge the setting of a battery is configured to 12 volts: 7 amps times 12 volts = 84w...

First Stabs at the RT8299 Hack
Log from $1/W True MPPT
In a previous project log I talked about using the RT8299 buck regulator and PWMing the enable pin to simulate a MPPT. While this isn't necessarily a textbook MPPT solution, it is an appealing one due to the high level of integration and low cost offered...
