How much electricity does a photovoltaic system produce a year?
Annual electricity production is measured in kWh (kilowatt hours). One kilowatt of peak photovoltaic power generates nearly 1,000 kilowatt-hours of electricity per year. If you are interested in this topic, you may be asking yourself: What performance should the system provide in the best case scenario?
How many kWh does a 4 person household consume a year?
A four-person household consumes an average of about 4,000 kWh per year. With an average PV output of 1,000 kWh per kW, this corresponds to a peak output of 4 to 5 kW of PV. In our example, we assume an annual consumption of 4,000 kWh. You can determine this average by looking at your electric bill for the past few years.

They also contribute to reducing the reliance on the main power grid and have a positive impact on the environment.
Micro Inverters
Micro inverters offer a unique advantage in solar power systems. Unlike traditional string inverters, each micro inverter is connected to a single solar panel, allowing for individual panel optimization. This means that even if one panel is shaded or has a lower performance due to some reason, it won't affect the overall output of the entire system. They are easy to install, highly efficient in converting DC to AC power, and provide better flexibility in system design, making them suitable for both residential and small commercial solar installations.
Roof - Integrated Photovoltaic Power Stations
Roof - integrated photovoltaic power stations combine the functionality of solar power generation with the aesthetics of building design.
