In this article, we release real data from a solar installation with only 8 solar panes on a mid-terrace house in the UK. We collecting data for 12 months starting in January 2020 until December 2020. Our research is useful for the consumers because they can evaluate how much energy they can generate from solar panels and how much they can save if they install energy storage.
The installation under rigorous examination has a 5kW Solis Hybrid Inverter, lithium-ion energy storage, and 285W solar panels.
It might sound like a small number of panels but on sunny days there is enough electricity to offset 100% of the cost of electricity. The diagrams below illustrate the total energy production Vs consumption. It is important to take into account that part of the energy consumed (energy drawn from the national grid) was purchased at an “economy tariff ” £0.05/kWh.
