At the end of August 2022, we had 19 panels installed (7.2kW), a Solax hybrid inverter, and batteries.
The panels are located at the rear of the house, because we’re in the UK (facing roughly SE 138 °). The two 5.8kW batteries are located in a utility room, so they shouldn’t get too hot or too cold.
The panels were been successful from day one. By 11am, batteries are full and we’re exporting electricity to the grid. On our electricity providers usage graph above, it’s obvious to see when the solar panels were installed.
However, now that we’re in winter the solar production has been reduced. To compensate, we’ve changed our electricity provider to access a six hour cheap overnight tariff (10p), which means we can recharge the batteries (peak price is 44p) run some appliances overnight.
We’re considering increasing the solar array to ~ 10kW) and to increase battery storage (we can add up to four batteries to our Solax hybrid inverter).
