Low Cost 10kW Solar System - One Year Later

Tags: Electronics, Finland, Hardware, Solar

A little over a year ago I published an overview of my off-grid solar system consisting of 10kW of panels and 28kWh LiFePo4 battery. The set-up consisted of all the components to run this solar system - including charge controllers, inverter, BMS, etc. The target goal was a cost of under €10K, which I managed to achieve with some cash to spare. Now that it has been in operation for a year, let's see how well the system held up, any issues that were encountered, and what the current price of the system would be were we to build it again today.

Building an off-grid 10kW solar system with 28kWh LiFePO4 battery, inverter, BMS and charge controllers for under €10K

Over the past decade or so I've been working on off-grid solar installations big enough to power a house, even during the long, cold (and dark) winter months here in Finland. While November, December and January remain challenging, it can actually be done - and pretty well. The issue in the past has been that doing this was quite expensive. The first implementations I built for this ran in the multiple tens of thousands of Euro and required quite some attention to keep going. These first systems relied on expensive components and difficult to manage and heavy lead-acid batteries. Over the past few years however, the landscape has changed and there are possibilities that I could only dream of even as little as a year ago. The post below details the components, where to get them, requirements, and the cost to get an off-grid solar system with several days of autonomy running for under 10K Euro.

Midsummer

Tags: Finland, Other

Last weekend, we celebrated Midsummer in Finland. It's one of those highlights in a Finnish calendar year, but we missed it for many years in a row due mostly to work related travel. This year was different. Midsummer is the celebration of the summer solstice, and marks the day with the longest period of daylight. Where we are, this is 24 hours - the sun never sets. We spent the day in a typical Finnish manner: get out, enjoy nature, the quietness, family, with food and drinks.
